Description

Technical Field

[0001] This utility model relates to the field of steel shearing, and in particular to a shearing machine for automotive stamping parts. Background Technology

[0002] The first key process in the production of automotive stamping parts is shearing—cutting rolled metal sheets (coils) or whole flat sheets into "blanks" that meet the requirements of subsequent stamping processes (such as blanking, deep drawing, and bending) using a shearing machine.

[0003] For example, patent document CN222059625U discloses a shearing machine for automotive stamping parts, including a worktable and an automatic feeding mechanism. The automatic feeding mechanism includes a housing, a mounting frame, a motor, a mounting block, a first connecting rod, a spring, a fixed rod, a linkage component, and a push plate. The motor drives the mounting block and the first connecting rod to rotate, causing the spring to deform and compress. At the same time, the first connecting rod drives the linkage component to move horizontally in the direction of the fixed rod. The linkage component drives the push plate to move, and the push plate enters the slot in the housing, pushing the sheet metal in the housing. This solution solves the problem that manual handling of sheet metal is time-consuming and labor-intensive, increasing the workload of operators and reducing production efficiency.

[0004] In the existing technology, the raw material is in the form of steel coils. After being extended by a leveling machine, it enters a shearing machine. Some shearing machines use traction components to pull the metal sheet into the space between the upper and lower shears. However, most of the current traction components complete the clamping and traction work through multiple power components and control systems. This type of control and manufacturing costs are relatively high. Utility Model Content

[0005] The purpose of this utility model is to provide a shearing machine for automotive stamping parts in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A shearing machine for automotive stamping parts includes a conveying mechanism. A traction mechanism is located at the top front end of the conveying mechanism, comprising two traction hydraulic rods with a first inlet connector fixedly connected to each rod. A clamping mechanism is located at the top rear end of the conveying mechanism, comprising two clamping hydraulic rods with a second inlet connector fixedly connected to each rod. A shearing mechanism is located at the rear side of the conveying mechanism, including a lifting frame. A hydraulic linkage mechanism is located at the lower rear end of the conveying mechanism, comprising two cylinder supports with two symmetrically arranged linkage piston cylinders fixedly connected to each support. The two linkage piston cylinders are slidably connected to the same bidirectional piston rod, which is fixedly connected to the lifting frame via a linkage rod. The lower linkage piston cylinder is connected to the second inlet connector via a fixed hydraulic pipe, and the upper linkage piston cylinder is connected to the first inlet connector via a hydraulic hose.

[0008] Preferably, the conveying mechanism includes a rear support, a feeding platform is fixedly connected to the top of the rear support, and several evenly distributed rotating rollers are rotatably connected to the feeding platform. The rear support is fixedly connected to two cylinder supports.

[0009] Preferably, a feeding clamping roller is rotatably connected to the top front side of the rear support, and two elastic telescopic columns are fixedly connected to the top front side of the rear support. Movable frames are fixedly connected to the elastic telescopic columns, and another feeding clamping roller is rotatably connected between the two movable frames.

[0010] Preferably, the traction mechanism further includes two translation screws rotatably connected to the left and right sides of the rear support. The two translation screws are connected to a synchronous belt and a synchronous pulley. A power motor is fixedly connected to the lower front end of the rear support. The power motor is connected to one of the translation screws via a chain and sprocket. A translation bracket is threaded onto the translation screw. The translation bracket is slidably connected to the rear support. A traction hydraulic rod is fixedly connected to the upper end of the translation bracket. An upper clamping plate is fixedly connected to the output end of the traction hydraulic rod. A lower clamping plate is fixedly connected to the translation bracket. The lower clamping plate is correspondingly set to the upper clamping plate.

[0011] Preferably, the clamping mechanism further includes a fixed bracket fixedly connected to the top of the rear end of the rear support, a clamping hydraulic rod fixedly connected to the fixed bracket, a pressure plate slidably connected to the output end of the clamping hydraulic rod, and a return spring fixedly connected between the pressure plate and the clamping hydraulic rod.

[0012] Preferably, the shearing mechanism further includes a front support fixedly connected to the rear side of the rear support, an upper support fixedly connected to the top of the front support, a lifting frame slidably connected to the upper support, a pressure lever rotatably connected to the top of the upper support, one end of the pressure lever being hinged to the lifting frame via a connecting rod, and the other end of the pressure lever being provided with a straight through groove, a hydraulic drive rod fixedly connected to one side of the front support, the output end of the hydraulic drive rod being hinged to the straight through groove on the pressure lever, a lower cutting blade fixedly connected to the top of the front support, and an upper cutting blade fixedly connected to the lifting frame.

[0013] The beneficial effects are as follows: by setting up a hydraulic linkage mechanism, during the lifting process of the lifting frame, the two linkage piston cylinders and the bidirectional piston rod work together to drive the pressing hydraulic rod and the traction hydraulic rod to move asynchronously, thereby realizing the pressing and traction of the steel plate. This avoids the use of complex control systems and too many power components, reduces the cost of the device, and facilitates the promotion of the device.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-8As shown, a shearing machine for automotive stamping parts includes a conveying mechanism. A traction mechanism is located at the top front end of the conveying mechanism, comprising two traction hydraulic rods 204, each with a first inlet connector 207 welded to it. A clamping mechanism is located at the top rear end of the conveying mechanism, comprising two clamping hydraulic rods 302, each with a second inlet connector 303 welded to it. A shearing mechanism is located at the rear side of the conveying mechanism, comprising a lifting frame 406. A hydraulic linkage mechanism is located at the lower rear end of the conveying mechanism, comprising two cylinder supports 506, each with two symmetrically arranged linkage piston cylinders 502 welded to it. The two linkage piston cylinders 502 are slidably connected to the same bidirectional piston rod 501, which is bolted to the lifting frame 406 via a linkage rod 503. The lower linkage piston cylinder 502 is connected to the same bidirectional piston rod 501 via a connecting rod 503. The fixed hydraulic pipe 504 is connected to the second inlet connector 303. The upper linkage piston cylinder 502 is connected to the first inlet connector 207 through the hydraulic hose 505. In use, after the steel falls onto the conveying mechanism, the lifting frame 406 rises. The lifting frame 406 drives the linkage rod 503 to rise, and the linkage rod 503 drives the bidirectional piston rod 501 to rise. As a result, the space inside the upper linkage piston cylinder 502 becomes smaller, and hydraulic oil is introduced into the traction hydraulic rod 204 through the hydraulic hose 505. Then, the traction hydraulic rod 204 extends to clamp the steel plate, and can then move the steel plate. At the same time as the bidirectional piston rod 501 rises, the space inside the lower linkage piston cylinder 502 becomes larger. The hydraulic oil inside the pressing hydraulic rod 302 is drawn into the linkage piston cylinder 502 through the fixed hydraulic pipe 504. Then, the pressing hydraulic rod 302 retracts, canceling the clamping and fixing of the steel plate. Thus, the steel plate can move under the action of the traction mechanism.

[0030] The conveying mechanism includes a rear support 101, a feeding platform 102 is fixedly connected to the top of the rear support 101, and several evenly distributed rotating rollers 103 are rotatably connected to the feeding platform 102. The rear support 101 is fixedly connected to two cylinder supports 506. The arrangement of several rotating rollers 103 ensures that the steel plate can move smoothly on the feeding platform 102 and avoids hard friction.

[0031] A feeding clamping roller 106 is rotatably connected to the top front side of the rear support 101. Two elastic telescopic columns 105 are fixedly connected to the top front side of the rear support 101. Movable frames 104 are fixedly connected to the elastic telescopic columns 105. Another feeding clamping roller 106 is rotatably connected between the two movable frames 104. In use, the steel material that has passed through the leveling device enters the device between the two feeding clamping rollers 106. The two feeding clamping rollers 106 play a guiding role, and the setting of the elastic telescopic columns 105 enables the two feeding clamping rollers 106 to automatically adapt to steel materials of various thicknesses.

[0032] The traction mechanism also includes two translation screws 201 rotatably connected to the left and right sides of the rear bracket 101 by bearings. The two translation screws 201 are connected to a synchronous belt and a synchronous belt pulley. The synchronous belt drive here is a model with a large load capacity. A power motor 202 is bolted to the lower front end of the rear bracket 101. The power motor 202 is connected to one of the translation screws 201 via a chain and sprocket. A translation bracket 203 is threaded onto the translation screw 201. The translation bracket 203 is slidably connected to the rear bracket 101. A traction hydraulic rod 204 is bolted to the upper end of the translation bracket 203. The traction hydraulic rod 204 outputs... The upper clamping plate 206 is fixedly connected to the end bolt, and the lower clamping plate 205 is fixedly connected to the upper bolt on the translation bracket 203. The lower clamping plate 205 is set correspondingly to the upper clamping plate 206. In use, the power motor 202 drives the translation screw 201 on one side to rotate. The translation screw 201 drives the other translation screw 201 to rotate synchronously through belt transmission. The translation screw 201 drives the translation bracket 203 to move. The translation bracket 203 drives the traction hydraulic rod 204 to move. The traction hydraulic rod 204 extends and drives the upper clamping plate 206 to move. The lower clamping plate 205 clamps the steel plate with the upper clamping plate 206. Thus, the movement of the translation bracket 203 can drive the steel plate to move.

[0033] The clamping mechanism also includes a fixed bracket 301 fixedly connected to the top of the rear end of the rear support 101. The clamping hydraulic rod 302 is fixedly connected to the fixed bracket 301. The output end of the clamping hydraulic rod 302 is slidably connected to a pressure plate 304. A return spring 305 is fixedly connected between the pressure plate 304 and the clamping hydraulic rod 302. When shearing, it is generally necessary to clamp and fix the steel plate near the shearing mechanism to prevent the steel plate from moving during shearing. Therefore, a clamping mechanism is provided. When the lifting frame 406 descends, the clamping hydraulic rod 302 is driven to drive the pressure plate 304 to descend. The pressure plate 304 abuts against the steel plate. Then the lifting frame 406 continues to descend, but the pressure plate 304 does not move. Therefore, the return spring 305 contracts and generates a reaction force.

[0034] The shearing mechanism also includes a front support 401 fixedly connected to the rear side of the rear support 101. An upper support 402 is fixedly connected to the top of the front support 401. A lifting frame 406 is slidably connected to the upper support 402. A pressure lever 404 is rotatably connected to the top of the upper support 402. One end of the pressure lever 404 is hinged to the lifting frame 406 via a connecting rod 405. The other end of the pressure lever 404 is provided with a straight through groove. A hydraulic drive rod 403 is fixedly connected to one side of the front support 401. The output end is hinged to the straight through slot on the pressure lever 404. The lower cutting blade 408 is fixedly connected to the top of the front bracket 401, and the upper cutting blade 407 is fixedly connected to the lifting frame 406. In use, the hydraulic drive rod 403 drives the pressure lever 404 to rotate. The pressure lever 404 amplifies the force and transmits it to the connecting rod 405. The connecting rod 405 pushes the lifting frame 406 to descend. The lifting frame 406 drives the upper cutting blade 407 to descend. The upper cutting blade 407 and the lower cutting blade 408 cooperate to cut the steel plate.

[0035] Working Principle: Steel, after passing through the leveling device, enters the device between two feeding rollers 106. Several rotating rollers 103 ensure smooth movement of the steel plate on the feeding platform 102, avoiding hard friction. After the steel falls onto the feeding platform 102, the lifting frame 406 rises, driving the connecting rod 503 to rise. The connecting rod 503 then drives the bidirectional piston rod 501 to rise. This reduces the space inside the upper connecting piston cylinder 502, allowing hydraulic oil to flow through the hydraulic hose 505 into the traction hydraulic rod 204. The traction hydraulic rod 204 then extends to clamp the steel plate. Subsequently, the power motor 202 drives one side of the translation screw 201 to rotate. The translation screw 201 drives the other translation screw 201 to rotate synchronously via belt transmission. The translation screw 201 drives the translation bracket 203 to move, which in turn drives the traction hydraulic rod 204 to move. Thus, the movement of the translation bracket 203 moves the steel plate. As the bidirectional piston rod 501 rises, the space inside the lower linkage piston cylinder 502 increases. Hydraulic oil inside the clamping hydraulic rod 302 is drawn into the linkage piston cylinder 502 through the fixed hydraulic pipe 504. As a result, the clamping hydraulic rod 302 contracts, releasing the clamping and fixing of the steel plate. Thus, the steel plate can move under the action of the traction mechanism. The hydraulic drive rod 403 drives the pressure lever 404 to rotate. The pressure lever 404 amplifies the force and transmits it to the connecting rod 405. The connecting rod 405 pushes the lifting frame 406 to descend. The lifting frame 406 drives the upper cutting blade 407 to descend. The upper cutting blade 407 and the lower cutting blade 408 cooperate to cut the steel plate. As the lifting frame 406 descends, it simultaneously drives the clamping hydraulic rod 302 to drive the pressing plate 304 to descend. The pressing plate 304 abuts against the steel plate. Then the lifting frame 406 continues to descend, but the pressing plate 304 does not move. As a result, the return spring 305 contracts, generating a reaction force to press the steel plate tightly.
