Technical Field
[0001] This utility model relates to the field of metal sheet shearing technology, specifically a sheet shearing device for processing bimetallic rolled bushings. Background Technology
[0002] Bimetallic bearings are a type of oil-free lubricated bearing. This product uses high-quality low-carbon steel as the base material, with lead-tin bronze alloy sintered on the surface. It is made of bimetallic strip that integrates copper and steel through several high-temperature sintering and dense rolling processes. It is suitable for various applications such as bushings and thrust washers that bear medium-speed and high-impact loads. Before the metal sheet needs to be rolled into a bushing, it needs to be cut by a sheet shearing device.
[0003] Existing sheet metal shearing devices for bimetallic rolled bushings can shear metal sheets, but after a period of use, the shearing blades wear down, causing the sheared sheet to curl. Therefore, the shearing blades need to be disassembled and polished regularly to prevent the cutting edge from becoming dull. This results in infrequent maintenance of the shearing blades and slow polishing, leading to low overall efficiency and inconvenience for the sheet metal shearing device. Therefore, we propose a sheet metal shearing device for bimetallic rolled bushings. Utility Model Content

A controller is installed on the outside of the bracket, and a material feeding groove runs through the shearing table near the top.
[0008] Preferably, the base is rotatably connected to the top of the support near the bracket, and a fixed frame is symmetrically fixedly connected to the top of the base corresponding to the top of the support. A second hydraulic rod is installed on the fixed frame, and a support frame is installed at one end of the second hydraulic rod near the middle of the base. A limit roller is rotatably connected to the support frame.
[0009] Preferably, the top height of the conveying support roller is equal to the height of the bottom of the inner side of the material feeding trough.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This invention, when shearing metal sheets with a shearing blade, uses a drive mechanism to move a bracket and its grinding mechanism to one end of a support plate, thus misaligning the bracket and grinding mechanism with the shearing blade to avoid obstructing the shearing blade's movement. When the shearing blade's edge needs grinding, a first hydraulic rod lifts the shearing blade, and the drive mechanism moves the bracket back and forth. When the bracket, along with the grinding plate, presses against the end of the shearing blade, the inclined side of the grinding plate forces the grinding plate and mounting plate to overcome the spring force and move towards the support plate. The grinding plate, through the spring, presses against both sides of the shearing blade. This movement of the grinding plate grinds the shearing blade's edge. This sheet metal shearing device allows for maintenance of the shearing blade without disassembly, effectively shortening maintenance time and improving sheet metal shearing efficiency.
[0015] This invention uses two sets of staggered mounting plates and grinding plates to avoid mutual interference between the bottoms of the grinding plates on both sides. Rectangular columnar guide rods and guide rod grooves guide the movement of the mounting plates and grinding plates, preventing them from deflecting when grinding the shearing blade. At the same time, the grinding plates are detachably connected to the mounting plates by bolts, allowing the grinding plates to be replaced, thus ensuring the grinding effect on the shearing blade.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a sheet metal shearing device for processing bimetallic rolled bushings, comprising a base 1, a bracket 2 fixedly mounted on the top of one side of the base 1, and first hydraulic rods 3 symmetrically mounted on the top of the bracket 2, wherein...
[0022] The first hydraulic rod 3 is equipped with a lifting plate 4 at the bottom of the inner side of the bracket 2. A shearing blade 5 is installed at the bottom of the lifting plate 4. A shearing table 11 is installed on the base 1 at the top of the shearing blade 5. A support 12 is installed inside the bracket 2 near the top. A bracket 13 is slidably provided on the side of the support 12 near the shearing blade 5. The bracket 13 is driven by the drive mechanism to slide along the support 12.
[0023] Support plates 18 are fixedly installed on the top of both sides of the support 12. A guide rod groove 19 is passed through the support plate 18. A guide rod 20 is passed through the guide rod groove 19. A baffle 21 is fixedly connected to the end of the guide rod 20 away from the shearing blade 5. A mounting plate 22 is fixedly connected to the end of the guide rod 20 near the shearing blade 5. A grinding plate 23 is installed on the side of the mounting plate 22 away from the guide rod 20. A spring 24 is sleeved on the guide rod 20 between the mounting plate 22 and the support plate 18. A controller 25 is installed on the outside of the bracket 2. A material passage groove 26 is passed through the shearing table 11 near the top.
[0024] When shearing metal sheets with the shearing blade 5, the drive mechanism moves the bracket 13 and its grinding mechanism to one end of the support plate 18, causing the bracket 13 and its grinding mechanism to be misaligned with the shearing blade 5, thus avoiding obstruction to the lifting and lowering of the shearing blade 5. When the cutting edge of the shearing blade 5 needs to be ground, the first hydraulic rod 3 drives the shearing blade 5 to rise, and the drive mechanism drives the bracket 13 to reciprocate. When the bracket 13 drives the grinding plate 23 to abut against the end of the shearing blade 5, the inclined side of the grinding plate 23 causes the grinding plate 23 and the mounting plate 22 to be forced against the spring force of the spring 24 and move towards the support plate 18. The grinding plate 23 abuts against both sides of the shearing blade 5 through the spring 24. The movement of the grinding plate 23 grinds the cutting edge of the shearing blade 5. With this sheet metal shearing device, the shearing blade 5 can be maintained without disassembly, effectively shortening the maintenance time of the shearing blade 5 and thus improving the shearing efficiency of the sheet metal.
[0025] Please see Figures 1 to 3 A conveyor support roller 6 is rotatably connected to the top of the base 1 near the support 2. A fixed frame 7 is symmetrically fixed to the top of the base 1 corresponding to the conveyor support roller 6. A second hydraulic rod 8 is installed on the fixed frame 7. A support frame 9 is installed at one end of the second hydraulic rod 8 near the middle of the base 1. A limit roller 10 is rotatably connected to the support frame 9. The top height of the conveyor support roller 6 is equal to the height of the bottom of the inner side of the material passage 26. When the metal sheet is fed, the conveyor drives the metal sheet to move. The metal sheet is supported by the conveyor support roller 6. The distance between the limit rollers 10 on both sides can be adjusted by the second hydraulic rod 8, thereby guiding the feeding of the metal sheet and preventing the metal sheet from deviating during feeding. After the metal sheet passes through the material passage 26, the shearing force of the shearing blade 5 and the end profile of the shearing table 11 completes the shearing of the metal sheet.
[0026] Please see Figures 1 to 3 The drive mechanism includes a slide groove 14. The support 12 has a slide groove 14 on the side near the bracket 13. A slider 15 is fixedly connected to the side of the bracket 13 near the slide groove 14. A lead screw 16 is rotatably connected to the slide groove 14 and threadedly connected to the slider 15. A motor 17 is installed on the outer side of the bracket 2 corresponding to the end of the support 12. The shaft end of the motor 17 is fixedly installed to the shaft end of the lead screw 16. When the motor 17 drives the lead screw 16 to rotate in the forward and reverse directions, the lead screw 16 drives the slider 15 to move back and forth in the slide groove 14 through the threaded connection. In turn, the slider 15 drives the bracket 13 and the grinding structure on it to move back and forth so as to grind the cutting edge of the shearing blade 5.
[0027] Please see Figures 1 to 3The guide rod 20 is a rectangular column, and its external dimensions match the internal dimensions of the guide rod groove 19. The mounting plate 22 and the grinding plate 23 have the same shape as the bottom of the shearing table 11. The mounting plates 22 and the grinding plates 23 on both sides of the bracket 13 are staggered, and the mounting plates 22 on both sides of the bracket 13 are fixedly connected by bolts. The staggered mounting plates 22 and the grinding plates 23 prevent the bottoms of the grinding plates 23 on both sides from affecting each other. The rectangular column guide rod 20 and the guide rod groove 19 guide the movement of the mounting plates 22 and the grinding plates 23, preventing the mounting plates 22 and the grinding plates 23 from deflecting when grinding the shearing blade 5. At the same time, the grinding plate 23 is detachably connected to the mounting plate 22 by bolts, which allows the grinding plate 23 to be replaced, thereby ensuring the grinding effect on the shearing blade 5.
[0028] Working Principle: This sheet metal shearing device for processing bimetallic rolled bushings operates by moving the support 13 and its grinding mechanism to one end of the support plate 18 via a drive mechanism when shearing the metal sheet with the shearing blade 5. This misaligns the support 13 and its grinding mechanism with the shearing blade 5, preventing obstruction to the lifting and lowering of the shearing blade 5. When the cutting edge of the shearing blade 5 needs to be ground, the first hydraulic rod 3 drives the shearing blade 5 upward, and the drive mechanism drives the support 13 to move downward. The device moves back and forth. When the bracket 13 drives the grinding plate 23 to abut the end of the shearing blade 5, the inclined side of the grinding plate 23 causes the grinding plate 23 and the mounting plate 22 to move towards the support plate 18 under the force of the spring 24. The grinding plate 23 abuts against both sides of the shearing blade 5 through the spring 24. The movement of the grinding plate 23 grinds the cutting edge of the shearing blade 5. With this plate shearing device, the shearing blade 5 can be maintained without disassembly, which effectively shortens the maintenance time of the shearing blade 5 and improves the shearing efficiency of the plate.
[0029] When feeding metal sheets, the conveyor drives the metal sheets to move. The metal sheets are supported by the conveyor support rollers 6, and the distance between the limit rollers 10 on both sides can be adjusted by the second hydraulic rod 8, thereby guiding the feeding of the metal sheets and preventing them from deviating during feeding. After the metal sheets pass through the feeding groove 26, they are sheared by the shearing force of the shearing blade 5 and the profile at the end of the shearing table 11. When the motor 17 drives the lead screw 16 to rotate forward and backward, the lead screw 16 drives the slider 15 to move back and forth in the slide groove 14 through the threaded connection, thereby moving the slider... 15 drives the bracket 13 and its grinding structure to reciprocate, so as to grind the cutting edge of the shearing blade 5. The two sets of mounting plates 22 and grinding plates 23 are staggered to prevent the bottoms of the two grinding plates 23 from affecting each other. The rectangular columnar guide rod 20 and guide rod groove 19 guide the movement of the mounting plate 22 and grinding plate 23 to prevent the mounting plate 22 and grinding plate 23 from deflecting when grinding the shearing blade 5. At the same time, the grinding plate 23 is detachably connected to the mounting plate 22 by bolts, so that the grinding plate 23 can be replaced, thereby ensuring the grinding effect of the shearing blade 5.
