Abstract
New type tandem mill triangle guide device featuring integrated guide device. Bottom of the guide device is triangle guide block and top of the guide device is round bar connecting rod. They are fastened with bolts. The cross section of guide block with guide trough is almost an isosceles triangle, two symmetrical and same arc curved surfaces along guide trough with the radius a little larger than that of roller. Another one surface is plane. Viewing from vertical section, guide trough, top surface and bottom surface are in parallel with each other. Guide trough, size and guide block height can match with original separate triangle guide. During the installation, fasten the combined guide block and connecting rod to fixed yokes on the side wing of 3rd and 4th frame roller of RSM and align round guide trough hole to roller hole trough. Then, during the working, the rolling stock can bite into roller hole trough through the guiding of guide trough hole. The utility model features rational design, easy installation and maintenance, low producing cost and can basically avoid roller explosion during the rolling. Production cost of hot rolling metal wire is low and the efficiency is high.
Description
Technical field
The utility model relates to the auxiliary equipment of metallurgy industry tandem mill, refers in particular to the rolling mill guide and guards that is used for the metal wire rod hot rolling line.
Background technology
Metal wire rod is common metallurgic product.The production procedure of hot-rolling metal wire rod is: after the steel billet heating, under the guiding of guide and guards (guide red base rolled piece can correctly nip the pass slotted eye of rolling mill roll), enter tandem rolling unit (roughing unit, mm finishing mill unit) thermal processing distortion, be rolled into the straight little pole of size up to specification, arrive Laying head at last, become metal wire rod dish circle.
The RSM of U.S. MORGAN company subtracts that to decide unit be common wire rolling tandem mill, its guide and guards that subtracts 3,4 frames of deciding unit is the triangle guide and guard, its design feature is: these triangle guide and guard are split-type structural, mainly are made up of 2 guide and guard parts (guide and guard components A and guide and guard part B) and 1 connecting rod; Guide and guard components A, B are " the isosceles triangle bulks that upper surface and lower surface are parallel to each other ", 2 sides of triangle drift angle are that (in the middle of the curved surface is circular arc line to symmetrical curved surface, two ends are straight tangent lines), 1 side is plane (perpendicular bisector on this plane is exactly the line of symmetry of 2 curved surfaces) in addition, and position, 2 triangle base angles has 1 bolt connecting hole respectively; The upper surface of guide and guard components A has the semicircle guide and guard groove A of 1 indent, and guide and guard groove A is consistent with line of symmetry; The lower surface of guide and guard part B has the semicircle guide and guard groove B of 1 indent, and guide and guard groove B is consistent with line of symmetry, and upper surface has 1 to protrude piece; Connecting rod is other shaped, and top is 1 small cylinder, and the bottom is 1 block triangle that mates with the guide and guard part dimension, and block triangular base has 1 breach that mates with guide and guard part B upper surface protrusion piece size; 2 bolts pass bolt connecting hole, and 2 guide and guard parts (guide and guard components A and guide and guard part B) and 1 connecting rod are joined together, constitute triangle guide and guards (Fig. 4), and semicircle guide and guard groove A and semicircle guide and guard groove B constitute 1 circular guide and guard slotted eye.During work: the triangle guide and guards is arranged in the flank (small cylinder on other shaped connecting rod top of two rolls of tandem mill frame, be fixed on the fixed mount of roll 3 flanks), circular guide and guard slotted eye is aimed at the roll Pass slotted eye, guide correctly the nip pass slotted eye of rolling mill roll of red base rolled piece, finish the hot-working rolling deformation of rolled piece.
In the actual production, being arranged in the RSM of MORGAN company subtracts and decides machine the 3rd, the above-mentioned triangle guide and guards of 4 breast roller flanks, because the requirement of installing space position and the correct guide and guard of rolled piece, the interval of guide and guards and roll is very little, average about 2.5mm, and the tiny difference of triangle guide and guard and roll shape (roll is circular, in the middle of the guide and guard curved surface is circular arc line, two ends are straight tangent lines), make only 0.685mm of minimum interval, and triangle guide and guard parts adopt be casting of metals spare (in general, organizing of casting of metals spare is more loose, crystal grain is thicker, the metal obdurability is relatively poor), therefore, easily cause the triangle guide and guard of the 4th frame to bring the roll Pass slotted eye in the operation of rolling, cause that (just quick-fried roller: triangle guide and guard and rolled piece impact roll or roll Pass slotted eye in the collars explosion, make roll, the pass explosion, distortion), cause roll, the triangle guide and guards damages (1 quick-fried roller, can cause the loss from spoilage of 1～2 roll and triangle guide and guards) direct economic loss, and the economic loss (processing time of 1 quick-fried roller spends 45 minutes approximately) that descends of milling train production capacity; Have a strong impact on the RSM of MORGAN company and subtracted the ordinary production of deciding machine.
Summary of the invention
The purpose of this utility model provides a kind of novel tandem mill triangle guide and guards, at first adopt " overall structure that guide and guard parts, connecting rod join together " replacement " split-type structural of 2 guide and guard parts, 1 connecting rod ", improve the obdurability of triangle guide and guard; Secondly, make the curved surface of triangle guide and guard into circular arc line, with the form fit of roll 3, eliminate the minimum interval of guide and guards and roll 3, reduce the generation of quick-fried roller phenomenon, enhance productivity, reduce production costs, satisfy the production requirement that the tandem mill production line runs well.
The novel tandem mill triangle guide and guards that the utility model provides is characterized in that: guide and guards is 1 monolithic construction, and the bottom is a triangle guide and guard piece 1, and top is round bar shape connecting rod 2, and both are fixedly connected; Guide and guard piece 1 bulk triangular in shape, guide and guard piece 1 upper surface and lower surface are parallel to each other, height H=(0.5～1.2) * (h1+h2+h3), and H 〉=h1+h2, the triangular cross section of guide and guard piece 1 is 1 approximate isosceles triangle, and 2 sides of isosceles triangle drift angle are arc-shaped surfaces symmetrical, that equate, the radius R=r+ of arc-shaped surface (2～5) mm, r is the radius of roll 3, and 1 side is plane in addition; Circular guide and guard groove is arranged in the triangle guide and guard piece 1, from cross section, the line of symmetry of guide and guard groove and isosceles triangle is overlapping, from the longitudinal section, guide and guard groove and guide and guard piece 1 upper surface (or lower surface) are parallel to each other, the distance H 1=h1 of guide and guard groove and guide and guard piece 1 lower surface; Be fixed on the connecting rod 2 on guide and guard piece 1 top, length L=(h1+h2+h3-H)+L1, h1, h2, h3, L1 are respectively guide and guard components A, guide and guard part B, the height of connecting rod 2 lower triangle bulks and the length of top small cylinder of architomia formula structure triangle guide and guards; Above-mentioned in conjunction with constituting the utility model.
Triangle guide and guard piece 1 is fixedly connected with round bar shape connecting rod 2, and can adopt bolt to connect: the upper surface center of triangle guide and guard piece 1 is provided with the bolt hole of 1 indent, and the end of round bar shape connecting rod 2 is bolt shape, and both size couplings are fixedly connected.
