The cutting pliers is a shearing device specially used for cutting slender materials such as cables and links. It is a large-sized scissors and is designed by using the principle of "lever" and "inverse ratio of pressure to area". Cutting pliers are widely used in ports, electric power, steel, shipbuilding, petrochemical, mining, railway, construction, metallurgical and chemical, automobile manufacturing, plastic machinery, industrial control, highway, large-scale transportation, pipeline auxiliary, slope tunnel, well treatment Protection, marine assistance, offshore engineering, airport construction, bridges, aviation, aerospace, stadiums and other important industries as well as the mechanical equipment required for various infrastructure projects. The usual cutting pliers are equipped with high carbon steel tungsten alloy steel blades, which can quickly cut cables, links, etc., and are durable.

In order to strengthen the strength and convenience of the cutting pliers, the cutting pliers developed the ratcheting pliers from the traditional manual pliers, and hydraulic shearing pliers, electro-hydraulic shearing pliers and all-electric cutting pliers appeared one after another. Also, for the convenience of transportation and maintenance, a split type pliers has been developed which can be used with an independent drive source such as a hand pump, an electric pump or the like. The two split cutters currently widely used are hydraulic/pneumatic cutters and electric cutters.

The hydraulic/pneumatic cutting pliers usually include a clamp on which the card slot, the link groove, the movable knife guiding groove and the static knife guiding groove are processed, and the hydraulic cylinder with the flange is stuck in the card slot, and the hydraulic cylinder body is There is a plunger, the left end of the movable blade is coupled with the right end of the plunger through the return disk, and then the hydraulic cylinder is inserted into the slot of the clamp through the flange thereof, and the movable blade is placed in the movable blade guiding groove of the clamp, stationary The blade is placed in the stationary blade guide slot of the clamp. when using it, Firstly, the cut cable (or link) is placed in the cutting tank, and then the high pressure liquid/gas is injected into the cylinder. Under the action of the hydraulic pressure/gas pressure, the plunger pushes the movable blade to move, and cooperates with the stationary blade. Shear forces are formed to shear the cable/link.

The electric cutting pliers uses a lithium battery as the power source. There are multiple sets of gears inside the machine. The multi-group gears rotate to drive the knife opening and closing. This electric cutting pliers can easily cut off large cables.

Applicants have found that there are some problems with the current cutting pliers. For example, the hydraulic pump/air pump may be overloaded, so that the blade continues to shear after the cable is cut, causing excessive shearing; there may be a force application during the shearing process. Balance, causing the blade to skew during the shearing process, and so on. These problems may cause the shear to fail to complete smoothly, or shorten the life of the cutting pliers.

Therefore, there is a need to design a new type of cable cutter that overcomes at least some of the problems of the prior art described above.

The actual use of the orientation is the same. In actual use, the orientation of the shearing device will be based on The operation changes.

A shearing apparatus and an application thereof according to an embodiment of the present invention will be described below with reference to Figs. 1a to 10 .

Referring first to Figures 1a, 1b, 1c, 2 and 3, a shearing device in accordance with one embodiment of the present invention is illustrated. Specifically, FIG. 1a shows an exploded perspective view of the shearing device, and FIGS. 1b and 1c show an assembled side cross-sectional view and a front cross-sectional view of the shearing device, wherein the configuration of the shearing device can be clearly seen, FIG. 2 shows An assembled perspective view of the shearing device in an unclosed state, and FIG. 3 shows an assembled perspective view of the shearing device in a closed state.

The shearing device of this embodiment can be used not only for shearing cables, links, but also for shearing steel bars, metal strands, and any other elongated material. The configuration of the shearing device according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Figures 1a to 1c clearly show the structure of the various components of the shearing device and the manner in which they are assembled. The shearing device is generally indicated at 10 and includes the following major components: support device 100, engagement device 200, linkage 300, and shearing member 400. The support device 100 serves as a basic support portion of the shearing device 10 for supporting and accommodating other components of the shearing device. The main function of the engaging device 200 is to connect the shearing device 10 to a driving source (not shown) to actuate the shearing device 10 by the driving force of the driving source. The linkage 300 is a transmission portion in the shearing device 10 that is operatively coupled to the engagement device 200 for transmitting driving force from the drive source to the shearing member 400. As can be seen from FIGS. 1a to 1c and 2, the joining device 200 is coupled to the lower portion of the supporting device 100, the linkage device 300 is disposed within the supporting device 100, and the shearing member 400 is supported on the upper portion of the supporting device 100 and is operable with the interlocking device 300. The ground connection is performed, whereby the shearing member 400 is connected to the engagement device 200 via the linkage device 300, and is further connected to the drive source, thereby realizing the transmission of the driving force from the drive source to the shearing member 400.

In particular, referring to Figure 4, there is shown a specific structure of a support device 100 in accordance with the present invention. As clearly shown in FIG. 4, a limiting portion 101 is provided within the support device 100 to define a maximum travel of the linkage 300. Preferably, the designing principle of the limiting portion 101 is such that its setting position matches the shearing action of the shearing member 400, which is arranged to allow the shearing member 400 to complete the cutting at the end of the stroke of the linkage device 300, Or slightly excessively shearing, at which time the moving part of the linkage 300 contacts and abuts against the limiting portion 101. Since the limiting portion 101 is provided, when the moving member of the linkage 300 (for example, the bracket 301 described later) is in the branch When the inside of the receiving device 100 is moved (the moving member is disposed below the limiting portion 101, which will be described later in detail), the moving member will contact and abut against the limiting portion 101 after moving a certain distance, thereby stopping the movement. In this way, the driving stroke of the driving source can be restricted by limiting the stroke of the interlocking device 300, whereby the excessive loading of the driving source can be prevented to cause premature failure of the driving source. Under this principle, the specific position of the limiting portion 101 can be adjusted according to the specific size and configuration of the moving member of the linkage 300 and the shearing member 400 without departing from the scope of the present invention.

Specifically, the configuration of the interlocking device 300 of the shearing device 10 of the present embodiment will be described with continued reference to FIGS. 1a, 5a to 5c, and 6a and 6b. In particular, the linkage 300 in the shearing device of the present invention has an anti-offset construction and arrangement to prevent eccentric loading during shearing, resulting in shear failure or shear component 400 damage. This is described in detail below.

The linkage 300 mainly includes a bracket (first coupling member) 301 and two links (second coupling members) 302, 312 that are coupled to the bracket 301 as shown in FIG. 1a. The bracket 301 is operatively coupled to the underlying engagement device 200 for receiving a driving force from the drive source through the engagement device 200. The links 302, 312 are coupled to the shearing member 400, whereby the bracket 301 and the shearing member 400 are operatively coupled to transmit the driving force to the shearing member 400 for the cutting operation.

In particular, the lower portions of both links 302, 312 each include a slot (not shown in the following description 302e) through which the links 302, 312 are operatively coupled to the bracket 301, as shown in Figure 1a. Figure 1b shows. This particular structure and arrangement is effective in preventing eccentric loads from occurring. The eccentric load problem usually occurs during the shearing process. When the drive source drives the shearing device, the sheared cable exerts a reaction force (torque) on the shearing device. This reaction force may cause the shearing device to occur. Offset, thereby causing the shearing device and the components connected thereto to twist. However, this can be avoided by the structural design of the present invention. According to the present invention, during the shearing process, the links 302, 312 are subjected to the torque applied by the shearing member 400, thereby tending to rotate. Since the connecting rods 302, 312 are coupled to the bracket 301 through the lower notch, the notch can firmly clamp the bracket 301, so that the links 302, 312 are not easily displaced and twisted in the lateral and lateral directions, thereby Effectively prevent eccentric loading from occurring. The structure of the links 302, 312 themselves will be described in more detail below.

Referring to Figures 5a, 5b and 5c, the structure of the bracket 301 is shown in more detail. As shown, the bracket 301 includes a horizontal connection portion 301a for connecting the lower engagement device 200 and a vertical connection portion 301b extending upward from the center of the horizontal connection portion 301a for connecting the link 302, 312. The specific manner of attachment of bracket 301 to engagement device 200 and links 302, 312 will be described in greater detail below.

Referring to Figures 6a and 6b, the structure of one of the links 302 is shown in detail. Since the structure of the link 312 is identical to the structure of the link 302, a detailed description thereof will be omitted. The link 302 has a laterally extending engagement portion 302a that is located centrally of the link 302 as a whole. The first connecting portion 302b extends upward from one end of the engaging portion 302a, and the shearing member 400 is pivotally coupled to the first connecting portion 302c (as shown in Fig. 1b). Further, a third connecting portion 302d and a second connecting portion 302c are extended downward from the one end and the opposite end of the engaging portion 302a, and the notch 302e is formed in the second connecting portion 302c and the third connecting portion 302d. The notch 302c is fitted to the bracket 301, and the second connecting portion 302c and the third connecting portion 302d are connected to the bracket 301.

A vertical connection portion 301b of the bracket 301 is disposed in the notch 302e and is pivotally coupled to the second connection portion 302c and the third connection portion 302d of the link 302 through the pin 303. The same is true for the link 312. Specifically, as shown in FIGS. 5a, 5b, 6a, and 6b, a pin hole 301d is formed in the vertical connecting portion 301b of the bracket 301, and the first connecting portion 302b and the third connecting portion 302d of the link 302 are formed. A corresponding pin hole 302f is formed in the upper portion. Thereby, the link 302 can be pivotally moved relative to the bracket 301.

With the notch 302e and the second connecting portion 302c and the third connecting portion 302d on both sides thereof, when the connecting rod 302 is subjected to an external deflecting force, the third connecting portion 302d is pressed against the deflection force. The side portion of the vertical connecting portion 301a can thereby further prevent the occurrence of deflection, and further improve the mounting stability and the anti-offset effect.

Preferably, as shown in Figures 5c and 6b, the bracket 301 has an inverted "T" shaped cross section and the link 302 has an "h" shaped cross section. In this case, the blade of the shearing member 400 is disposed inside the first connecting portion of the links 302, 312 as shown in Fig. 1b. On the one hand, this design is more compact and on the other hand ensures a good connection. Also, in this case, the two links 302, 312 are connected to the bracket 301 in opposite directions such that the respective first connecting portions of the links 302, 312 are located at two of the vertical connecting portions 301b of the bracket 301. On the side, this is also to ensure the balance of the force of the interlocking device 300 as a whole.

It should be noted that the link 302 is designed to be "h" type only to realize one side of the link 302. The link 302 can take any other form as long as the design principles of the present invention are met. For example, the connecting rod 302 can be designed as a simple cylindrical structure, which is formed with a notch below or above, and the upper notch is used to provide the shearing member 400, which can also achieve the technical effect of preventing the eccentric load, and has Relatively better stability. In addition, the bracket 301 can also have various designs, for example, for the horizontal connection portion 301a, it can adopt various shapes such as a circle, an ellipse, a rectangle, a square, or the like. Of course, in general, an axisymmetric shape is preferred in view of the eccentric load problem.

Further, the joining device 200 according to the present invention will be described with reference to Figs. 1a, 7a, 7b, 8, 9, and 10. In the illustrated embodiment, the engagement device 200 primarily includes a coupling component 201 and a transmission component 202 built therein. One end of the connecting member 201 is connected to the support device 100 in an assembled state, and the other end is connected to a drive source. The connecting member 201 is mainly used to connect the main body portion of the shearing device 10 with a driving source. At the same time, the transmission member 202 provided in the connecting member 201 is connected to the linkage device 300, and the driving source (specifically, the driving shaft) acts on the transmission member 202 via the connecting member 201, thereby transmitting the driving force to the transmission member 202 through The associated linkage 300 is in turn transferred to the shearing member 400 for the shearing operation. As described above, since the transmission member 202 is disposed in the connecting member 201, the connecting member 201 also functions as an outer casing of the transmission member 202 at the same time.

One embodiment of the connecting member 201 is shown in Figures 7a, 7b. In this example, the connecting member 201 includes an upper connecting portion 201a for connecting the main body portion of the shearing device 10 (specifically, the supporting device 100), and a lower connecting portion 201b, the lower connecting portion 201b is used to connect the drive source below. Further, a through hole 201c is formed in the connecting member 201, and the transmission member 202 is disposed in the through hole 201c and is movable therein. At the same time, the through hole 201c is also sized such that the drive shaft of the drive source can pass therethrough. More specifically, in the illustrated example, the upper connecting portion 201a may be fixedly coupled to the support device 100 by a tight fitting manner, and the lower connecting portion 201b is formed with a screw threadedly engaged with the driving source by a screw connection. Of course, any other suitable connection manner can be adopted. For example, the upper connecting portion 201a is connected to the supporting device 100 by means of a snap connection, a screw connection, a bonding, a welding, etc., and the lower connecting portion 201b can be connected according to the connected driving source. Type to choose the appropriate connection method.

Referring again to FIG. 1a, preferably, the engagement device 200 can further include an elastic member 203, The elastic member 203 functions as an elastic returning means to automatically reset the linkage 300 after the cutting operation is completed. Specifically, the resilient member 203 is configured to transmit a force between it and the transmission member 202 to enable the transmission member 202 to move. Since the transmission member 202 is coupled to the linkage 300 as described above, the elastic member 203 can thereby move the linkage 300 via the transmission member 202, thereby achieving elastic reset of the linkage 300. Further, according to the present invention, the elastic member 203 is disposed between the support device 100 and the connecting member 201. Specifically, one end of the elastic member 203 is adjacent to the lower end of the transmission member 202, and the other end abuts against the lower side of the support member 100. Therefore, when the transmission member 202 is subjected to the action of the driving source (specifically, the driving shaft), the elastic member 203 moves accordingly, and since one end abuts against the supporting member 100, the elastic deformation occurs due to the pressure, thereby After the driving force is removed, the elastic restoring force of the elastic member 203 causes the transmission member 202 and the linkage 300 connected thereto to be reset. The specific mode of operation of the transmission member 202 and the resilient member 203 will be described in greater detail below.

In the embodiment shown in FIG. 1 a , the connecting part 201 is embodied in the form of a threaded joint, the transmission part 202 is embodied in the form of a sleeve, and the elastic part 203 is embodied in the form of a helical spring. In the following, for the sake of brevity, the specific elements of the above-described components will be denoted by the same reference numerals. In this example, the sleeve 202 is disposed within the threaded joint 201, and the coil spring 203 is sleeved outside the sleeve 202 and abuts the lower end of the sleeve 202. Specifically, as shown, the coil spring 203 abuts the lower end of the sleeve 202 through the collar 204 and the washer 205. This connection facilitates the disassembly and assembly of the coil spring 203 and the sleeve 202. Of course, other connections are also possible, such as welding, bonding, and the like.

A view of the sleeve 203 is shown in FIG. It can be seen that both ends of the sleeve 203 are formed with annular grooves 202a and 202b. The lower end groove 202a is used to mount the collar 204 and the washer 205. The collar 204 is caught in the recess 202a, and the washer 205 is sleeved on the sleeve 202. Due to the blocking action of the collar 204, the washer 205 is held at the lower end of the sleeve 202, and the coil spring 203 can pass through the washer 205. The lower end of the sleeve 202 abuts. The upper end groove 202b is used to connect the linkage, specifically, the bracket 301. As shown in Fig. 5b, the lower side of the bracket 301 is formed with a recess 301c in which the upper end of the sleeve 202 can be disposed. At the same time, the lower side of the bracket 301 is also formed with a card slot 301d. After the upper end of the sleeve 202 is disposed in the recess 301c, the upper end of the sleeve 202 is fixed in position by the profile spring 304 in the recess 301c. A profiled spring 304 for securing is shown in Fig. 1a, as shown in the figure, the profiled spring 304 has an intermediate section 304a and two side sections 304a which, when fixed, engage the sleeve in the sleeve 202 In the upper end recess 301c, the side sections 304a on both sides are caught in the card slot 310d on the lower side of the bracket 301, thereby achieving a fixed connection of the sleeve 202 to the bracket 301. As can be seen in Figure Ia, the intermediate section 304a is formed with an arc corresponding to the annular recess 301c.

Of course, in addition to the connection by the profile spring 304 used in the present embodiment, the sleeve 202 may be adjacent to the bracket 301 by press fitting, welding, bonding, etc., which are all included in the scope of the present invention. Further, in addition to the sleeve 202 and the coil spring 203 used in the embodiment shown in the drawings, any other form of connecting member and elastic member may be employed. For example, the connecting member may be a rod member, and the elastic member may be surrounded. Any form of elastic member provided by the rod member, such as a sheet, strip, or other profiled elastic member, is also included within the scope of the present invention.

Next, the structure of the support device 100 according to the embodiment of the present invention will be described with reference to Fig. 4 . In the embodiment of FIG. 4, the support device 100 includes an interior space 102 for receiving a portion of the linkage 300, and in particular, a portion of the bracket 301 of the linkage 300 is received within the interior space 102. Moreover, as shown in FIG. 4, a limiting portion 101 for restricting the stroke of the interlocking device 300 (specifically, the bracket 301) is disposed at the top of the internal space 102, thereby passing through the internal space 102 and the limiting portion 101. The stroke of the bracket 301 is defined. The lower portion of the support device 100 further includes an opening portion 103 which is formed at the bottom of the internal space 102 as shown in FIG. 4, and a portion of the engagement device 200 (specifically, the transmission member 202) can pass through the opening portion 103.

Next, the configuration of the shearing member 400 of the shearing device 10 according to the present invention will be described with reference to Fig. 1a. The shearing member 400 includes a first blade 405 and a second blade 406 that are cut by a closure of the first blade 405 and the second blade 406 to cut a cable or the like. As shown in FIG. 1a, each of the first blade 405 and the second blade 406 includes a support portion 104 for use with the support device 100. The first connection of the connection. Taking the first blade 405 as an example, it includes a first connecting portion 401 that is pivotally mounted and supported on the support portion 104 by a screw 403 and a nut 408. To this end, the first connecting portion 401 and the supporting portion 104 are formed with corresponding mounting through holes. By pivotally supporting, the shearing member 400 is capable of pivotal movement relative to the support portion 104.

Further, with continued reference to FIG. 1a, the first blade 405 and the second blade 406 each include a second connection for connection to the links 302, 312 of the linkage 300. Still taking the first blade 405 as an example, it includes a second connecting portion 402 that is pivotally coupled to the link 302 of the linkage 300 by a pin 404. Similarly, the second connecting portion 402 and the connecting rod 302 are formed with corresponding mounting through holes.

As shown in FIG. 1a, the top of the first blade 405 is provided with a guiding block 407. When the first blade 405 and the second blade 406 are closed, the top of the second blade 406 enters the guiding block 407, thereby preventing the cable from being cut due to the process. The reaction of the blade causes the blade to tilt. It should be noted that, as can be seen from FIG. 1a, the inside of the first blade 405 and the second blade 406 are formed into a concave arc shape, when the first blade 405 and the second blade 406 are just joined, due to the inner concave The arcuate shape provides a space between the first blade 405 and the second blade 406 that is designed to just accommodate the cable therein without being cut into the cable. When the first blade 405 and the second blade 406 are further engaged with each other, the cutting starts, while the tip end of the second blade 406 starts to enter the guiding block 407 at the top end of the first blade 405. In this way, the blade can be skewed in an efficient manner as the shearing proceeds.

Furthermore, as shown in FIG. 1a, the shearing device 10 according to the present invention may further include a housing member 500 that may be used to protect the support device 100 and the shearing member 400. Specifically, the housing member 500 is disposed outside the support device 100, and the top is formed with notches 503, 504 for receiving the first blade 405 and the second blade 406 of the shearing member 400. The slots 503, 504 can allow the first blade 405 and the second blade 406 to pivotally move therein.

Specifically, in the illustrated embodiment, the housing member 500 includes a first half-shell 501 and a second half-shell 502 that are respectively disposed on both sides of the support device 100, and It is fixed to the support device 100 by screws 505. Of course, other fixing methods can also be used, such as snap-on bonding, bonding, welding, welding, and the like. The housing member 500 can be made of any suitable material, plastic is relatively common, its quality is light, and it has a certain hardness. Degree, can play a certain protective effect.

The above is a specific configuration of the shearing device 10 according to an embodiment of the present invention, and its mode of operation will be described below.

After the assembly is completed, the shearing device 10 is connected to an external driving source (for example, a hydraulic pump, a gas pump, an electric motor, etc.). The cutting is required to open the drive source, and the drive shaft (not shown) of the drive source pushes the transmission member 202 upward, and the transmission member 202 in turn pushes the bracket 301 connected thereto upward. During this process, the lower end of the elastic member 203 is also moved upward by the transmission member 202. Since the upper end of the elastic member 203 abuts against the lower side of the support device 100, the elastic member 203 undergoes compression deformation. At the same time, as the bracket 301 moves upward, the connecting rod 302 connected thereto will perform a pivotal movement, and at the same time, the connected first blade 405 and the second blade 406 are driven relative to the support portion 104 of the supporting device 100 and the connecting rod 302. Pivoting movement. The pivotal movement of the first blade 405 and the second blade 406 are brought close to each other for shearing. When the bracket 301 moves upward and abuts against the limiting portion 101, the bracket 301 will stop moving, and the driving source will also receive feedback to stop pushing the driving shaft to advance, thereby achieving excessive loading of the driving source. At this time, according to the design of the present invention, the shearing member 400 also completes the shearing operation, the cable is completely cut, and the shearing member 400 performs the cutting. Referring to FIG. 3, the first blade 405 and the second blade 406 are completely closed. And the concave curved portions are completely staggered with each other. At this point, the cutting process is complete. After the cutting is completed, the driving source will retract the driving shaft. At this time, the sleeve 202 is no longer subjected to the pressing force, the compressed elastic member 203 starts to recover, and the sleeve 202 is driven to move downward, and the sleeve 202 drives the upper end to be connected. The bracket 301 and the connecting rod 302 connected thereto move downward, and the link 302 also performs pivotal movement at the same time, and the downward movement and the pivoting movement of the link 302 cause the shearing member 400 to also reverse (open direction). In the pivotal movement, the first blade 405 and the second blade 406 are separated from each other to be fully opened. When the bracket 301 reaches the bottom of the internal space 102 of the support device 100, the downward movement is stopped, at which time the shearing member 400 is fully opened. Thus, a complete cutting operation process is completed.

Further, according to the present invention, there is also provided a shearing apparatus comprising a shearing device according to the present invention, and a corresponding external device capable of being coupled to the shearing device of the present invention to drive it Cutting operation.
