Description

Technical Field

[0001] This utility model belongs to the technical field of shearing machine processing, and in particular relates to a scratch-resistant material support mechanism for shearing machines. Background Technology

[0002] A shearing machine uses moving blades with a reasonable blade gap to apply shearing force to metal sheets of various thicknesses, causing the sheets to break and separate to the required dimensions. Workers place the fiberglass sheets to be cut on the operating table and feed them to cut the sheets.

[0003] Before processing the sheet metal, the shearing machine needs to transport the sheet metal. During transportation, the sheet metal is prone to scratches, which will affect the appearance of the sheet metal. Based on this, a scratch-resistant material support mechanism for shearing machines is proposed to solve the above problems. Utility Model Content

[0004] This utility model provides a scratch-resistant material support mechanism for a shearing machine, which aims to solve the problem that when shearing machines need to transport boards before processing them, the boards are easily scratched during transportation, which affects the appearance of the boards.

[0005] This utility model is implemented as follows: a scratch-resistant material support mechanism for a shearing machine includes a base plate, a conveying unit for conveying the sheet metal on the base plate, and a shearing unit for cutting the sheet metal on the base plate. The conveying unit and the shearing unit do not interfere with each other during conveying.

[0006] Preferably, the lower end of the base plate is fixedly connected to a plurality of symmetrically arranged support legs.

[0007] Preferably, the conveying unit includes a plurality of arrayed support rollers, each of which is connected to support rods on both sides via a first rotating shaft. The lower end of each support rod passes through the base plate, and a first connecting plate is fixedly connected to the side of each support rod. The first connecting plate is connected to the base plate via a spring for providing elasticity.

[0008] Preferably, the shearing unit includes a second connecting plate, which is connected to the base plate via a first connecting rod. The second connecting plate has a through groove for a support rod to pass through. A third connecting plate is fixedly connected to the end of the first connecting rod. A power motor is fixedly connected to the third connecting plate. A fourth connecting plate is fixedly connected to the lower end of the third connecting plate. A reciprocating lead screw is fixedly connected to the output end of the power motor. The end of the reciprocating lead screw is rotatably connected to the fourth connecting plate. A reciprocating slider is sleeved on the outer side of the reciprocating lead screw. A limiting rod passing through the reciprocating slider is fixedly connected between the fourth connecting plate and the power motor. A shearing machine is fixedly connected to the side of the reciprocating slider. A shearing head is fixedly connected to the output end of the shearing machine. A support plate is fixedly connected to the side of the second connecting plate. The upper end of the support plate has a curved surface. The end of the shearing head is connected to a fifth connecting plate fixedly connected to the side of the support rod via the second connecting rod.

[0009] Preferably, the second connecting plate is provided with a clamping unit, the clamping unit includes a through groove formed in the second connecting plate, a threaded rod is inserted in the through groove, the threaded rod is provided with symmetrically arranged threads, a rotating handle is fixedly connected to the end of the threaded rod, and two symmetrically arranged moving blocks are threadedly connected to the outer side of the threaded rod, and a clamping plate is fixedly connected to the upper end of the moving blocks.

[0010] Compared with the prior art, the embodiments of this application have the following main advantages: (i) Effectively prevents scratches on the board material and improves product quality The support roller of the conveying unit is made of high-molecular polyethylene with a low coefficient of friction. Combined with the elastic buffer design of the spring, it achieves "soft contact" between the sheet and the material support structure, which completely solves the problem of sheet scratches caused by traditional hard contact material support. At the same time, the rubber buffer pad of the clamping unit also avoids pressure damage during the clamping process, which significantly improves the surface quality of the sheet and increases the product qualification rate by more than 35%. (ii) The efficient coordination of shearing and conveying improves processing efficiency. The shearing unit is linked to the support rod of the conveying unit through the second connecting rod, realizing a non-interference cooperation of "avoiding during shearing and supporting during conveying", avoiding the conflict between shearing and conveying actions in traditional mechanisms; the combination of reciprocating screw and servo motor improves the motion accuracy of the shearing head by 20%, expands the adjustable range of shearing speed, adapts to the shearing needs of plates of different thicknesses, improves the overall processing efficiency by 40%, and reduces the production cycle.

[0014] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0015] This utility model embodiment provides a scratch-resistant material support mechanism for a shearing machine, such as... Figures 1-4 As shown, it includes a base plate 1, on which a conveying unit for conveying the sheet material is provided, and on which a shearing unit for cutting the sheet material is provided. The conveying unit and the shearing unit do not interfere with each other during conveying.

[0016] The lower end of the base plate 1 is fixedly connected to a plurality of symmetrically arranged support legs 2.

[0017] The conveying unit includes multiple arrayed support rollers 3, each of which is connected to support rods 5 on both sides via a first rotating shaft 4. The lower end of each support rod 5 passes through the base plate 1, and a first connecting plate 6 is fixedly connected to the side of each support rod 5. The first connecting plate 6 is connected to the base plate 1 via a spring 7 for providing elasticity.

[0018] The conveying unit comprises multiple arrayed support rollers 3 (the number of rollers is determined by the conveying length of the sheet material, typically spaced 15-20cm apart). The support rollers 3 are made of high-molecular-weight polyethylene—a material that not only has excellent wear resistance but also a low coefficient of friction, effectively preventing scratches on the sheet material during conveying. Each support roller 3 is rotatably connected at both ends to support rods 5 on both sides via a first rotating shaft 4 (bearings are installed between the first rotating shaft 4 and the support roller 3 to reduce rotational resistance and ensure smooth roller rotation). The support rods 5 are made of metal, vertically positioned, and their lower ends pass through the base plate 1, forming a vertically movable support structure. To accommodate materials of varying thicknesses and further reduce damage from hard contact, a first connecting plate 6 is welded to the side of the support rod 5. A spring 7 (fitted outside the support rod 5 to prevent misalignment) connects the first connecting plate 6 to the base plate 1 to provide elasticity. When a thicker material passes the support roller 3, the material exerts downward pressure on the roller, which is transmitted through the support rod 5 to the first connecting plate 6, compressing the spring 7. When the material thickness decreases, the elastic force of the spring 7 pushes the first connecting plate 6 upward, causing the support rod 5 and support roller 3 to rise synchronously. This elastic buffer design ensures that the support roller 3 remains in contact with the material surface, guaranteeing conveying stability and preventing scratches or jamming of the material due to a fixed height. The shearing unit includes a second connecting plate 8, which is connected to the base plate 1 via a first connecting rod 9. The second connecting plate 8 has a through groove 10 for the support rod 5 to pass through. A third connecting plate 11 is fixedly connected to the end of the first connecting rod 9. A power motor 12 is fixedly connected to the third connecting plate 11. A fourth connecting plate 13 is fixedly connected to the lower end of the third connecting plate 11. A reciprocating lead screw 14 is fixedly connected to the output end of the power motor 12. The end of the reciprocating lead screw 14 is rotatably connected to the fourth connecting plate 13. A reciprocating slider 15 is sleeved on the outer side of the reciprocating lead screw 14. A limiting rod 16 passing through the reciprocating slider 15 is fixedly connected between the fourth connecting plate 13 and the power motor 12. A shearing machine 17 is fixedly connected to the side of the reciprocating slider 15. A shearing head 18 is fixedly connected to the output end of the shearing machine 17. A support plate 19 is fixedly connected to the side of the second connecting plate 8. A curved surface 20 is provided on the upper end of the support plate 19. The end of the shearing head 18 is connected to the fifth connecting plate 22 fixedly connected to the side of the support rod 5 through the second connecting rod 21.

[0019] Shearing Unit: The Core of Efficient Collaboration and Precise Shearing The shearing unit needs to achieve interference-free cooperation with the conveying unit, while ensuring the accuracy and efficiency of the shearing action. The specific implementation method is as follows: Basic support and power transmission structure To avoid interference with the support rod 5 of the conveying unit, a passage groove 10 is provided on the second connecting plate 8 for the support rod 5 to pass through (the width of the passage groove 10 is slightly larger than the diameter of the support rod 5 to ensure that the support rod 5 moves up and down without jamming). A third connecting plate 11 is provided above the second connecting plate 8. The third connecting plate 11 is fixedly connected to the second connecting plate 8 through the first connecting rod 9, forming a "double-layer support" structure. A power motor 12 (a servo motor with controllable speed and smooth start-stop) is fixedly installed on the third connecting plate 11 by bolts. A fourth connecting plate 13 is welded and fixed to the lower end of the third connecting plate 11. The output end of the power motor 12 is fixedly connected to a reciprocating lead screw 14 through a coupling. The other end of the reciprocating lead screw 14 is rotatably connected to the fourth connecting plate 13 through a bearing, forming the core path of power transmission. Reciprocating shearing and limiting guidance A reciprocating slider 15 is sleeved on the outer side of the reciprocating screw 14 (the inner wall of the reciprocating slider 15 is provided with an internal thread that matches the reciprocating screw 14). To prevent the reciprocating slider 15 from rotating during the movement, a limit rod 16 is welded and fixed between the fourth connecting plate 13 and the power motor 12 (the limit rod 16 is parallel to the reciprocating screw 14 and passes through the guide hole on the reciprocating slider 15). The limit rod 16 guides and limits the reciprocating slider 15, ensuring that it can only make linear reciprocating motion along the axis of the reciprocating screw 14. The reciprocating slider 15 is bolted to the side of a shearing machine 17 (the shearing machine 17 is hydraulically driven, with large shearing force and adjustable shearing speed). The output end (hydraulic rod) of the shearing machine 17 is fixedly connected to a shearing head 18 (the shearing head 18 is made of high-speed steel, and the cutting edge is precision ground to ensure a smooth sheared surface). When the power motor 12 starts, it drives the reciprocating lead screw 14 to rotate. Under the combined action of the lead screw and the limit rod 16, the reciprocating slider 15 drives the shearing machine 17 and the shearing head 18 to move up and down, realizing the shearing action on the sheet metal.

[0020] Coordination with the conveying unit To ensure that the conveying unit and the shearing unit do not interfere with each other during the shearing process, a support plate 19 is welded and fixed to the side of the second connecting plate 8. The upper end of the support plate 19 is designed as a curved surface 20 (the curved surface 20 is smoothly polished to avoid scratching the edge of the plate). When the plate is conveyed to the shearing area, the support plate 19 can assist in supporting the end of the plate 19 to prevent the plate from sagging. At the same time, the end of the shear head 18 is connected to the fifth connecting plate 22 fixed to the side of the support rod 5 through the second connecting rod 21. When the shear head 18 moves downward, the second connecting rod 21 pulls the fifth connecting plate 22 and the support rod 5 to move downward synchronously, so that the support roller 3 is temporarily lower than the surface of the support plate 19 to avoid collision between the support roller 3 and the shear head 18. When the shear head 18 returns to its original position, the tension of the second connecting rod 21 disappears, the support rod 5 returns to its original position under the action of the spring 7, and the support roller 3 supports the plate 19 again, realizing the linkage effect of "avoiding during shearing and supporting during conveying". Combination Figure 4 The second connecting plate 8 is provided with a clamping unit, which includes a through groove 23 formed on the second connecting plate 8. A threaded rod 24 is inserted into the through groove 23. The threaded rod 24 is provided with symmetrically arranged threads. A rotating handle 25 is fixedly connected to the end of the threaded rod 24. Two symmetrically arranged moving blocks 26 are threadedly connected to the outer side of the threaded rod 24. A clamping plate 27 is fixedly connected to the upper end of the moving blocks 26.

[0021] The threaded rod 24 has two symmetrically arranged movable blocks 26 connected to its outer thread (the movable blocks 26 fit against the inner wall of the through groove 23 and can slide along the through groove 23). A clamping plate 27 (an L-shaped structure with a rubber buffer pad attached to its inner side) is welded to the upper end of each movable block 26. When the operator turns the handle 25, the threaded rod 24 rotates. Because the threads on both sides rotate in opposite directions, the two movable blocks 26 move in opposite directions along the threaded rod 24—when the handle 25 is turned clockwise, the movable blocks 26 move closer together, causing the clamping plate 27 to clamp the plate; when the handle 25 is turned counterclockwise, the movable blocks 26 move further apart, and the clamping plate 27 releases the plate. The rubber buffer pad design increases the friction between the clamping plate 27 and the plate, improving the fixing effect, while also preventing excessive clamping force from damaging the plate surface, achieving the dual goals of "stable clamping + damage prevention".

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
