Description

HIGH SPEED CUTTER BAND DESCRIPTIVE MEMORY This invention relates in general to cutter devices and, in particular, to a high speed cutter structure and band for cutting various natural and mixed aggregate and non-aggregate rock construction materials, which has reinforcement of steel or other material. A saw chain is commonly used to fell, saw and trim trees. The saw chain, the power head and the coupling components that make up a chainsaw for cutting wood have been highly developed. The steel cutting links of the saw chain slide along a steel guide bar at a high speed, driven by a drive sprocket that is connected to the drive shaft of the power head. The guide bar is a plate-shaped member with an oval guide edge provided with a guide groove flanked by guide rails. The chain of saw is made of pairs of central and lateral links. The center links include a dependent spigot that slides in the guide grooves and the side links have lower edges that slide over the guide rails. The cutting links, which are usually provided as one of the side links of each pair of side links, have an extended upward or outward portion formed toward the cutting edges that are directed forward. These cutting edges are attached to the body of the wood and cut chips of it. The complete process of cutting wood with a chain saw includes the sliding of metal over the patter of metal on the metal that is in reaction with the fast moving chain that attaches to the wood and removes the chips. The problem of wear is extremely acute, however, it has been largely overcome thanks to metal processing technologies that provide hard metal where wear resistance is desired, ductile metal where fatigue resistance is desired, etc. All this allows the production of a commercially possible wood cutting tool, that is, a chain saw with a reasonable average life at a reasonable cost. Cutting concrete, rock and other hard brittle materials requires a different type of cutting edge than that used to cut wood. Typically, such materials are cut with small cutting blocks composed of a metal matrix having graded industrial diamond particles impregnated therein. The blocks are attached to the cutting tool, that is, to the periphery of a round blade or to a steel cable. Circular knives are the most commonly used.

Chain saws have several problems that circular saws do not involve. The chain saw and the guidance system involve numerous parts sliding against each other. The side and center links rotate one relative to the other on rivets or bolts, the lower edges of the side links slide on the guide bar rails and the impulse extensions of the center links slide into the groove of the guide bar. Although the technology developed up to now allows this sliding relationship for the felling of wood, this is not the case for cutting aggregate material. When cement and rock are cut, fine particles of the aggregate medium are formed creating a powder that stays in the chain of the saw and its components. This powder gets between the sliding parts of the bar and the links of the chain and acts as an abrasive that quickly wears away the hardest part of the steel surfaces. Also, the heat generated when cutting the hard aggregate materials is so much that the similar sliding steel to steel creates an "adhesive" type of wear between the coupling parts. This is an inherent welding action that occurs due to the extensive heat that is generated between the parts. In this welding process pearls of the material are formed, which are broken into particles. The coupling surfaces wear out quickly over a period of time. However, the aforementioned problems are secondary. The main problem is the provision of a cutting element with sufficient duration. Obviously, if the chain of the saw can not retain the cutting element for any time, the fact that the movable or sliding parts wear out quickly is of little importance. The cutting element that is desired to cut aggregate material is a metal matrix impregnated with diamonds. It is not practical to make the cutting links with this material completely. Using a chain saw also limits the working area of the cutting surface since the size of the metal components of the chain determines the narrowest possible cut. Several patents of the prior art have attempted to solve the aforementioned problems. The U.S. Patent No. 4,603,678 to Fish discloses a device for cutting rock that includes a continuous flexible band of cutter to make a groove to a rock that is in the ground. The device includes a main frame, a boom mounted on the main frame by means of a pivot, aligned pulleys rotatably mounted to the main frame and the boom, a continuous flexible cutting band that extends around the driven coupling pulleys, and a means to rotate at least one of the pulleys. The continuous flexible cutting band includes a plurality of separate abrasive cutting elements that extend between the upper part and the sides of the band. The strength of the band is provided by means of a flexible cable that extends along the band. The patent of E.U.A. No. 4,679,541 to Fish is a continuation-in-part of Fish 4,603,678 and includes claims made to a embodiment having a groove in the upper and lower edges of the boom and an opening of outlet means in the groove, which allows water to be expelled. between the groove and the band to provide lubrication and reduce vibration as the band passes through the groove. During operation, the water thus expelled from the boom passes out of the groove into the cutting slot and washes the rock cuttings for improved performance. The patent of E.U.A. No. 4,920,947 of Scott et al. Discloses a chain saw for cutting aggregate materials that includes a chain saw with interconnected central links and pairs of side links composed of heat-treated steel. Certain pairs of the side links hold the cutting blocks of the matrix impregnated with diamonds that are laser welded to the side links in a procedure where the laser beam is centered and rotated along the joint to avoid voltage risers in the steel material of the support side links. The guide bar is provided with a pattern of adjoining channels to direct the water to the groove of the guide bar at spaced positions on the periphery of the edge of the guide bar to wash the aggregate powder that generated the cutting process.

The patent of E.U.A. No. 4,971,022 to Scott et al. Is related to No. 4,920,947, indicated above, and includes details of a cutting chain for aggregate materials. The structure of the cutting link is a bent plate-like member constituted by spaced portions of the side plate and an upper connecting network. The portions of the side plate function as side links on a conventional saw chain and go over the rails of a guide bar. The patent of E.U.A. No. 5,184,598 to Bell discloses an articulated saw chain for cutting aggregate material. The chain of the saw has sharp blocks stuck to pairs of side links and protectors formed or joined to pairs of side links that are placed between the successive cutting blocks. The protective portions extend substantially at the same height of the cutting block to prevent the edge of the cutting blocks from striking an object. The patent of E.U.A. No. 5,215,072 to Scott discloses a cutting element and a saw chain for cutting aggregate material comprising a saw chain having a right and left support link carrying the diamond mesh through the inclined support surfaces relative to the axis of travel of the chain. the chain of the sierra. The mesh impregnated with abrasive particles makes contact with the material that will be cut only adjacent to its trailing edge. There is a consumable material between the impregnated mesh and the support surface. The impregnated mesh can extend down the side of the support link to maintain a constant cutting width. The present invention is a high speed abrasive belt for cutting various natural and mixed rock construction materials, aggregates and non-aggregates, which has reinforcement of steel or other material. Designed to be used as a manual and / or assembled tool, it will contain a high percentage of plastic compounds. The main component of the system is a guide bar. A comprehensive water distribution system will help the conveyor to slide in the form of a belt, cooling and washing as well as keeping the wear associated with the adhesive and friction to a minimum, as well as the resulting power losses. The band comprises a wire rope, forming one or more endless turns, and will have segments impregnated with diamond mechanically tied to the wires. The driving pulley will be a metal molded and processed to accept a thermal spray tractive coating. Fig. 1 is a top perspective view of the cutting system of the invention, based on a band.

Referring to Fig. 1 of the drawings, a cut-off system based on a band is generally indicated with the number 10. Fig. 1 is a top perspective view of the system 10 showing the guide bar 27, the band of cutter 28, mounted on the guide bar 27, on the projection of the bar 30 and on the drive pulley 29. The drive pulley 29 will have a tractive coating (not shown) on the "V" shaped pulse or contains an insert ( not shown). The cutting system 10 based on a band of the invention are the consumable articles and finally the replacement components for the chain system of the prior art. The hydraulic motor and the related hydraulic system that is used to drive the cutting system 10 based on a belt are part of a Power Head manufactured and sold by RGC Corporation, P 0. Box 681, Buffalo, NY 14240 and will be described only in general terms. In the preferred embodiment, a modified C150 HYDRA CUTTER (not shown) was used. The hydraulics required to operate the system is 16 hp / 8GP / 1757 kg / cm2 and the water required is 1-2GPM / 281 kg / cm2. The previous version of the cutter used a segmented diamond chain saw for the cutting system. The names of the components are: one to three cutter band selections 28, one to three selections of bar nose 30, one to two guide bars 27 and one drive pulley 29. Due to an integral feature, the cutting system based in band 10 it requires this head of power to be able to work. This feature will control the band during start / stop and the cutting portion of the tool. The self-tensioning system senses the energy of the operator and temporarily tensiones the band 28. The identical parts that were observed in the preferred embodiment will first be put into use in the present model power head model C150 for retro-fitting purposes. The band-based cutting system 10 consists of consumable articles of a similar type and will replace the components of the chain-based cutting system in the present power head. The band can be made of thermoplastic polyurethane elastomer with polyether base, with fillers to intensify the properties, or thermoset polyurethane elastomer with polyether base, with fillers to intensify the properties. For making the band 28, injection molding or centrifugal molding methods can be used. The guide bar can be made of a thermoplastic polyurethane elastomer with a polyether base, with a matrix compound. The carbon fibers will be centered to give strength and overlap in order to obtain the mechanical properties that are required. The pultrusion procedure will also be used. In addition, an extruded aluminum guide bar can be used, having a hard / smooth coating thermally sprayed in the "V" groove 48. The projection of the rod 30 will be made of a polyether-based thermoplastic or thermoset elastomer with polyether base, with fillers to intensify the properties that are required. Injection molding and pressure molding processes will also be used. The drive pulley 29 will be made of alloyed aluminum to support the aforementioned tractive lining. The power is transmitted to the band 28 by means of a high coefficient of friction with the aforementioned tractive lining or insertion, with many "positive" coupling points, thus also eliminating the problems with the pitch change of the drive links 76 of the chain and the drive sprocket that has 14 teeth. The one-piece bar non-rotating projection with high wear resistance 30 will eliminate most of the problems currently encountered with the prior art system. Replace the bearings of the bar nose, the guide ring and the drive sprocket of the chain saw bar by a single replaceable spare part, will help in all other aspects of the cutting system, under some of the most severe operating conditions. The guide bar 27 is another consumable item in the system and offers an integral water distribution system consisting of double tanks to provide the water required by the band 27 below. The water distribution system comprises the water inlet 35, plugs 36 of the reservoirs, water reservoirs 32 and water outlets 33. The extensions 31 of the bar projection, which fit within the reservoirs 32, provide water through the water outlets 33 to the groove "V" 51 of the bar projection 30 and retain the bar projection 30 paired with the guide bar 27. The segmented band 28 is encased with a high wear resistance polymer material 43, such such as the urethane, which will make contact with the tool during the cutting process and also guide the band 28 through the groove "V" 48 in the guide bar 27 and the bar protrusion 30, resulting in a very cutting tool operation. uniform, very straight and very stable. The guide bar is another consumable item in the system and offers an integral water distribution system consisting of 32 double water tanks to supply the water that is required. The two reservoirs 32 make the guide bar 27 a bar different from all the other guide bars and allows a minimum pressure drop between the water supply and the water outlet orifices, water outlets 33. The water coolant and lubricant 46 it will disperse towards the rail surfaces (90 * "V") of the groove "V" 48 of the guide bar 27 from the reservoirs 32 to float the band 28 around the guide bar 27 during cutting. The hydrodynamic float of the band 28 under pressure makes this guide bar different from all other guide bars on the market. The water outlets 33 will be adjusted to distribute the water stream at a working pressure of at least six holes by means of which the current percentages of the tanks 32 will be adjusted to 50 to 75% of that current to the bar projection 30. This will allow the band to float freely around the projecting bar 30 with minimal power losses, while continuing to cool and wash the system. Figures 6 to 14 show details of the band 28. A first embodiment shown in Figures 6-8 uses a flat steel tape tension member 42 as the base for manufacturing the band 28. A second embodiment shown in Figures 9- 11 uses a cable tension member 44 as the basis for the manufacture of the band 28. The loss of segments is avoided with the use of a single tension member attached with a connection point, for a minimum of two times the average life of the cable. design. Both ends are joined, either by inserting them into a stop connector using a high strength / low temperature melted metal to cover and join within the stop connector, or by press fitting cable connectors at predetermined intervals for the integrity that is required. The tension members 42 or 44 are tensioned prior to the molding process to ensure proper "sizing" of the strips 28. In a first specific example of the web 28, the tension member 42 was a flat strip of wide stainless steel. 0.025 cm x 0.521 cm (.010"x .205") with 100 matrix segments 40 welded on top of band 28, in equal spaces, A abrasive segments of matrix 40 were given a spacing of 0.521 cm (.250") between each 100 segments In a second specific example of the band 28, the tension member 44 was a continuous rope cord ring, with a diameter of 0.159 cm (1/16"), with 100 matrix 40 segments glued to the anchors 45 and welded to the tension member 44 with thin brass material. The segments of the matrix 40 can be formed, for example, with a composition of cobalt, iron, nickel, carbide and industrial diamonds. The set of tension members 42 or 44 is then put into tension in a mold. Then the urethane 43 is molded over the whole. The reliefs 41, for the removal of particle material, are molded and centered between the segments. In a specific example, reliefs 41 were 0.318 cm (.125 inches) long x 0.0521 cm (.205 inches) wide x 0.0762 cm (.030 inches) deep, with 50 reliefs 41 per band 28. The initials of the The manufacturer 38 and the identification of the type of band 39 are molded on the upper surface of the band 28. Each of the segments of the matrix 40 and the tension members 42 and 44 will be completely encapsulated with urethane 43. In the two specific examples described previously, the width of the segments of the matrix was 0.521 cm and the length was 1435 cm from edge to edge. The width of the segments of the matrix 40 can be within a range of 0.470 to 0.521 cm in width. The height of the segments of the matrix 40 from the abrasive surface 37 and the bottom of the urethane band in the form of "V" 28 was 0.447 cm. In the second example of the web 28, with the tension member 44, the web 28 has a 0.051 cm urethane thickness common to both sides of the bottom of the anchors 45. In this application, the use of urethane or polyurethane is synonymous. Figures 12 to 14 describe a third embodiment using tension members 44 of wire ropes wrapped in a continuous loop and thus forming a double wrapping with the anchors 45 having two wire ropes moving therethrough, side by side, and bent inward towards the anchors 45. The ends of the two wire cables 44 are roll and overlap heights (not shown), in one example of a preferred embodiment, the overall height of the web 28 was 0.630 cm, the width of 0.521 cm, the length of the anchor 45 was 0.635 cm and the width of the anchor 45 was 0.521 cm. Reliefs 41, not shown in Figs. 12 to 14, can also be provided. In addition, manufacturer's initials 38 will be provided in a space between the segments of die 40. Shaped band 28 will generally be produced in at least three versions , General Purpose (PG), Green Concrete (CV) and Heavy Steel (AP). The identification of the type of band 39 will indicate the purpose of the band. The band-based cutting system 10 of the invention is a versatile and efficient cutting tool and can be used in construction, remodeling, maintenance, demolition and rescue. The system will cut through reinforced concrete (prestressed cable, pre-obstruct or wire), natural stone, tile for construction, concrete block, pumice block and stone mixtures. It will be used for: piston cutting to a total depth of 40.64 cm; corner cut - square corner cuts for doors, windows and air conditioners, eliminates perforation and over cuts, bottom cut - light portability and ease of manual handling allow for clean cuts at the bottom or base of the wall; Slotted Impact Cut - Any size slotted slotted cut is achieved cleanly and easily including corners and angles spliced; and finishing cut or expansion joint cuts to a total of 40.64 cm of increased versatility of a tool. Below is a comparison of the band-based cutting system 10 of the invention with the chain-based and table-saw devices of the prior art, which are described below: Comparison between Band / Chain Table Saws / Stone a. A reduced mass / inertia reduction allows the web 28 to move 40% faster than the prior art devices. b. A reduction of centrifugal effects / the movement of the band is minimized since it remains in guide rails in the form of "V" at 90 °. c. A reduced width / less material removal means less cleaning without horsepower. d. A segment height / reduced band height for the width aspect ratio stabilizes the band. and. A reduced cost / makes the system more convenient and more profitable. F. A reduced aspect ratio / allows better control of the dynamics of the band. g. The reduced premature loss of lateral space / provides means to limit and control. h. Reduced choices / reduces field problems when "bad" band is used. i. Frequent low voltage requirements / designed self-tensioning system. j. Designing a known life expectancy for each of the designs of band / cross-sectional design and plastics created will produce known quantities through extensive testing. k. Color coder in the design and part number system / band manufacturing will allow to mold bands in the desired colors with the part numbers, etc., as part of the procedure. Guide Bar / Chain Guide Bar / Band Guide Bar a. They reduce the total weight / the lighter the tool, the more comfortable it will be. b. They reduce the width of the bar / this allows a narrower cutter component. c. Increase the stability of the band / the top and bottom of the bar 27 are changed to a configuration of the groove in the form of "V" 48 to 90 °. d. Decrease water pressure drop / all enlarged supply paths. and. They introduce water control means / the bar has double water tanks, distribute the water with more uniformity than the systems of the prior art, without "leaving it without feeding". F. They introduce a constant water supply system / allow any water supply to connect to the tool and supply the correct flow and working pressure. g. They reduce the wear of the rail of bar / the trip of the band on the rails offers some resistance to the pressurized water that is escaping. h. They eliminate the problem of the projection area / projection bar 30 consumable, it is designed without rotation, for the multi-part rotating sprocket projection.

Outgoing Bar / Outgoing Gear Wheel a. Eliminate the problems of the sprocket ledge / the reduced part functions to guide the strip below the "V" shaped slot 51 and reduce the wear related to the sliding friction of the strip 28 on the bar boss 30 b. Design for consumable life expectancy / testing of various plastics and designed metals, and will allow to determine the properties required for a known life. c. Design to be recyclable / each plastic will be recyclable for environmental reasons. In addition to the mechanical advantages of the present invention, there are many safety advantages over chain-based cutting systems: a. The parts are designed for specific work in this cutter system to do the intended function. This results in the ability to determine the life expectancy of each part in the system independent of the other parts, thus providing a reliable safety design factor for the tension member (flat steel belt 42, cable 44). b. The very small number of parts reduces the number of potential failure points in the cutter system. This is by far the most important safety aspect addressed with this web-based cutter system, namely, the total reduction of the number of parts. c. The very small mass of cutter component reduces the centrifugal forces acting on the tensor member, this ultimately results in increased fatigue and reduced overall life expectancies. d. The removal of material during the cutting process is reduced by narrowing the cutter component, resulting in reduced slippery working surface conditions to which operators are constantly subjected. and. The limited interruption top surface of the abrasive resistant polymer web virtually eliminates the potential for it to "snag" during the cutting operation, which results in a smooth cutting action and reduces the deformation of the tension member. f. It eliminates having to re-tension the cutter component frequently due to the automatic tensioning system. Cutting systems of the prior art offer a means to manually adjust the tension to an interval dictated by the tool operator, which subjects the cutter component to uneven segment wear and may result in a tendency to throw the chain from the tool , when it is not stressed again regularly. In addition to the safety advantages of a belt system over a chain-based cutter system, there are many mechanical advantages: a. The most consumable item will be by far the 28 band and the 30 bar ledge. Cutting a wide variety of aggregates with a limited selection of bands 28, using a link / segment 40 matrix "General Purpose" to satisfy 20-80 % of the possible cutting applications of the tool. b. Cutting of soft concrete and abrasive aggregate, made by man such as, brick, paving stone, pre-cast hollow core floor and roof panels, etc., using a second bond / segment type "abrasive" to satisfy 10-30 % of these applications. c. Cutting of hard aggregates with or without steel content, using a third link / matrix of segment type "hard aggregate and steel" to satisfy the balance of 10-50% of these applications. d. Cutting of concrete products loaded with rod (up to 2.54 cm in diameter and including this diameter) and products that have high strength steel cable pretensioned inside them. and. The smaller selection of three "Bands" to cut a wider variety of materials will help simplify the band selection procedure by the customer. (An application overlap of 10-20% is designed) f. The web-based cutter system 10 of the invention has been developed to offer a direct wear relationship between each of the consumable components. g. The band 28 slides through its travel around the guide bar 27 using the water inlet 46 to cool, wash, and band 28 is floating hydrodynamically during the operation. h. The energy of the web 28 is transmitted by a high pulley coefficient 29 without many positive attachment points, furthermore eliminating the problems with the change in inclination in the driving and chain sprocket teeth. i. The segmented band 28 is completely covered with a wear-resistant polymeric material that will come into contact with the workpiece during the cutting process and will also guide the band down the "V" -shaped groove 48 of the guide bar 27, resulting in a very stable, very straight and very smooth cutting tool operation. j. The one-piece, non-rotating, high-wear-resistant bar nose 30 will eliminate most of the problems that are now experienced with prior art systems. Replacing the bar nose bearings, the inner race and the sprocket of the chain saw bar, with a single replaceable part will help the other aspects of the cutter system 10. k. The guide bar 30 is another consumable article in the system and offers an integral water distribution system 46 consisting of double tanks 32 to supply the necessary water. These two reservoirs 32 make the guide bar 27 distinctly different from the other guide bars, and allow a minimum pressure drop between the water supply and the water outlet doors, water outlets 33. 1. Water 46 will be dispersed in the surfaces of the slot 48 of the guide bar 27 so that the band 28 floats around the guide bar 27 during cutting. The band 28 that floats hydrodynamically under pressure on the guide bar 27 and on the bar projection 30 makes this system uniquely of the prior art guide bars on the market. Furthermore, by using the hydraulic principle of "raising" the band 28 of the bar projection 30, it also eliminates the need for a rotating projection wheel. m. The water outlet doors, water outlets 33 are "adjusted" to the water flow rate at a working pressure to at least six outlets 33, hence the flow percentages of the tanks will be adjusted to disperse 50- 75% of the flow to the rod ledge 30. This will allow the band 28 to rotate freely around the bar 30 ledge with minimal losses of horsepower, while cooling and washing the system continues. n. The color coding of all molded parts will eliminate the problems associated with poor identification of similar components. or. Each consumable will be clearly identified with its respective part number for inventory control purposes. p. Each consumable will have its respective recycling symbol molded into it, so that it can be returned to the manufacturer for a "partial credit" in the purchase of new replacement components. The operating advantages of the band-based cutter system 10 of the invention are: a. Horsepower requirements at the cutting edge are reduced by 20% and are proportional to the reduction in width by 20%. b. Cutting speed increased by 20% making the width of the cutter component narrower from 0.635 to 0.508 cm and 0.45 cm possible. c. Cutting speed increased by 18% running the band 28 to 1525 meters of surface per minute against 1251 mspm. d. Resulting functionality increased by 38% calculated. This is directly equivalent to an increase in the productivity and value of the product. and. Band 28 of the cutter component stabilized by a belt tensioner system sensitive to the pressure of the operator. The more effort the operator exerts during cutting, the more the band will tighten until it jams. This binding is an indicator for the operator to "back off" and let the tool do the work. F. The known wear ratios between the drive pulley components 29, the guide bar 27, the bar projection 30 and the band, allow the "end user" to be able to repeat a cutting job with confidence and at the same time be able to take advantage of the precise repetition. g. The silent operation of the friction drive system further improves the noise suppression problems of the chain-based cutter system of the prior art. h. The absence of articulation joints in the band 28 further stabilizes the matrix segments 40. This reduces the patterns of excessive wear occurring in those joints as the segment "tilts" upward when it comes into contact with the workpiece and loses Cutting diamonds potential for premature wear. i. The total length of the matrix segment 40 has been adjusted to the ratio of its new cutting width to help stabilize the diamond cutting component which also reduces premature wear of the segments. j. The profile of the matrix segment 40 has a radius at both ends to further prevent it from "snagging" on the material being cut. While the present invention has been designed in relation to the preferred embodiments thereof, it will be understood that those skilled in the art can make many changes and modifications of this invention without departing from the true spirit and scope thereof. For example, other types of materials can be used instead of polyurethane for each of the sub-assemblies. Accordingly, the appended claims seek to cover all such changes and modifications so as to be within the true spirit and scope of the present invention. The reader is asked to determine the scope of the invention by the appended claims and their equivalents, and not by the examples given.
