Description

Technical Field

[0001] This invention relates to the field of stamping technology, specifically to a stamping machine for producing battery covers for three-wheeled electric vehicles. Background Technology

[0002] A mold is a tool that shapes a blank into a part with a specific shape and size under external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics, and other products. A mold has a specific contour or internal cavity shape. Using a contour shape with a cutting edge allows the blank to separate along the contour line. Molds are precision tools with complex shapes, bearing the expansion force of the blank. They have high requirements for structural strength, rigidity, surface hardness, surface roughness, and machining accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing. Stamping is required in the production process of battery covers for three-wheeled electric vehicles.

[0003] According to Chinese Patent Publication No. CN211027677U, a stamping die for producing battery covers for electric vehicles is disclosed. The die includes a base, a mounting frame below the base, a screw jack on the mounting frame, and a servo motor threadedly connected to the mounting frame. A frame is located above the base, a lower support plate at the bottom of the frame, and a worktable above the lower support plate. Support shafts are located on both sides of the worktable. The design is reasonable; the screw jack can precisely control the rise and fall of the worktable, and the high-pressure cylinder enables the power head to perform stamping. It is highly practical, and the frame prevents impurities from splashing after stamping, ensuring high safety. Currently, existing battery cover stamping machines require demolding after stamping the battery cover, a process that requires manual intervention, affecting stamping efficiency. Therefore, a stamping machine for producing battery covers for three-wheeled electric vehicles is proposed to solve the aforementioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a stamping forming machine for producing battery covers for three-wheeled electric vehicles, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a stamping forming machine for producing battery covers for three-wheeled electric vehicles, comprising a machine body, a base provided on the machine body, a lower mold fixedly connected to the base, a guide post fixedly connected to the upper surface of the machine body, a top plate fixedly connected to the upper end of the guide post, a first hydraulic cylinder fixedly connected to the upper surface of the top plate, a hydraulic plate fixedly connected to the bottom of the first hydraulic cylinder, a top mold mechanism provided on the base, and a removal mechanism provided on the base;

[0006] The top mold mechanism includes a limiting cylinder and a lifting column. The lifting column is inserted into the inside of the limiting cylinder. A limiting plate is fixedly connected to the lower end of the lifting column. An abutment plate is fixedly connected to the lifting column. A spring is sleeved on the limiting cylinder. A top block is fixedly connected to the upper end of the lifting column. A top frame is fixedly installed on the abutment plate of the lifting column. A top column is fixedly connected to the upper surface of the top frame. After the workpiece is placed on the top block inside the lower mold, the first hydraulic cylinder is activated to lower its hydraulic plate, causing the upper mold at the bottom of the hydraulic plate to press down on the workpiece in the lower mold. The top block and four top columns move downward under pressure, compressing the spring. When the workpiece is stamped into a battery cover, as the hydraulic plate is raised, the top block and four top columns are raised under the action of the spring, thereby lifting the battery cover in the lower mold, making it easier to demold the formed battery cover.

[0007] The removal mechanism includes a fixed base and a sliding rod. The sliding rod is fixedly connected to the fixed base, and a movable base is slidably connected to the sliding rod.

The first through hole facilitates the lifting and lowering of the top block, and the second through hole facilitates the vertical movement of the top column.

[0010] Preferably, there are four top pillars, which are fixedly connected to the four corners of the upper surface of the top frame. By setting four top pillars, the four corners of the battery cover can be lifted, thereby facilitating the quick demolding of the battery cover.

The setting of the first limiting rod and the first limiting hole can play a limiting and guiding role for the fixed plate, so that the fixed plate can be stably raised and lowered under the action of the second cylinder.

[0012] Preferably, the fixed plate is provided with a second limiting hole, and a second limiting rod is inserted into the second limiting hole. The second limiting rod is fixedly connected to the fixed frame. The base is provided with a discharge groove. The second limiting hole and the second limiting rod can play a limiting and guiding role for the fixed frame, so that the fixed frame can move stably left and right under the action of the third cylinder.

[0013] Preferably, the fixed frame is provided with an adjustment mechanism, which includes a bearing and a bidirectional screw. The bearing is fixedly connected to the fixed frame, and the bidirectional screw is fixedly connected to the inner wall of the inner ring of the bearing.

[0014] Preferably, the first clamping block is threadedly connected to the bidirectional screw, and the first clamping block has an internal threaded hole. The bidirectional screw is threadedly connected to the inside of the internal threaded hole, and a second clamping block is threadedly connected to the bidirectional screw. A throttle is fixedly connected to the bidirectional screw. By rotating the throttle, the operator can drive the bidirectional screw to rotate, thereby adjusting the distance between the first clamping block and the second clamping block, which is convenient for clamping battery covers of different sizes.

[0015] Preferably, the base has a storage slot, and the inner wall of the storage slot has a limiting groove. A limiting block is slidably connected inside the limiting groove, and the limiting block is fixedly connected to the side wall of the base.

The telescopic end of the second hydraulic cylinder is fixedly connected to a connecting plate. The connecting plate is fixedly connected to the bottom of the base. By activating the second hydraulic cylinder, the connecting plate can be pushed to move the base, making it easier to move the base out of the hydraulic plate and allowing the staff to easily maintain the structural components on the base.

[0017] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0018] 1. The stamping forming machine for producing battery covers for three-wheeled electric vehicles uses the cooperation between the limiting cylinder, lifting column, top block, abutment plate, spring, top frame, top column, spring groove, first through hole, second through hole and limiting plate to place the workpiece on the top block inside the lower mold. Then, the first hydraulic cylinder is activated to lower the hydraulic plate, causing the upper mold at the bottom of the hydraulic plate to press down on the workpiece in the lower mold. The top block and four top columns move downward under pressure, compressing the spring. When the workpiece is stamped into a battery cover, as the hydraulic plate rises, the top block and four top columns are lifted under the action of the spring, thereby lifting the battery cover in the lower mold, which facilitates the demolding of the formed battery cover.

[0019] 2. The stamping machine for producing battery covers for three-wheeled electric vehicles utilizes the cooperation between a fixed seat, sliding rod, first cylinder, moving seat, mounting seat, second cylinder, fixed plate, third cylinder, fixed frame, first clamping block, sliding hole, first limiting hole, first limiting rod, second limiting hole, second limiting rod, and discharge groove. When the battery cover is lifted by the top mold mechanism, the second cylinder is activated to raise the fixed plate to a suitable position. Then, the third cylinder pushes the fixed frame closer to the battery cover, allowing it to be clamped by the clamping blocks on both sides. After completion, the second cylinder raises the fixed plate again, completely detaching the battery cover from the lower mold. The first cylinder then pushes the mounting seat along the sliding rod, moving the clamped battery cover above the discharge groove. At this point, the third cylinder drives the clamping blocks to reset, allowing the battery cover to fall onto the discharge groove for unloading. The process requires no manual intervention, achieving automated demolding and unloading, thus improving the production efficiency of battery covers for three-wheeled electric vehicles.

[0020] 3. The stamping machine for producing battery covers for three-wheeled electric vehicles, through the cooperation of bearings, a double-acting screw, a second clamping block, an internal threaded hole, and a throttle, allows the double-acting screw to rotate according to the size of the battery cover. This adjusts the distance between the first and second clamping blocks, ensuring they abut against appropriate clamping points on the battery cover. This makes the battery cover more stable during demolding and removal, preventing instability and potential drops, and facilitating the clamping of battery covers of different sizes.

[0021] 4. The stamping machine for producing the battery cover of this three-wheeled electric vehicle, through the cooperation between the base, storage groove, limiting groove, recess, second hydraulic cylinder, connecting plate and limiting block, allows the connecting plate to be pushed to move the base along the direction of the limiting groove when maintenance and repair of the structural components on the base are required. This facilitates moving the base out of the hydraulic plate and avoids the inconvenience of maintenance and repair of the structural components on the base being under the hydraulic plate, further improving the practicality of the stamping machine.

[0035] Please see Figure 1-6 One embodiment of the present invention is: a stamping forming machine for producing battery covers for three-wheeled electric vehicles, comprising a machine body 1, a base 10 provided on the machine body 1, a lower mold 5 fixedly connected to the base 10, a guide post 6 fixedly connected to the upper surface of the machine body 1, a top plate 7 fixedly connected to the upper end of the guide post 6, a first hydraulic cylinder 8 fixedly connected to the upper surface of the top plate 7, a hydraulic plate 9 fixedly connected to the bottom of the first hydraulic cylinder 8, a top mold mechanism 2 provided on the base 10, and a removal mechanism 3 provided on the base 10;

[0036] The top mold mechanism 2 includes a limiting cylinder 201 and a lifting column 202. The lifting column 202 is inserted into the inside of the limiting cylinder 201. A limiting plate 211 is fixedly connected to the lower end of the lifting column 202. An abutment plate 204 is fixedly connected to the lifting column 202. A spring 205 is sleeved on the limiting cylinder 201. A top block 203 is fixedly connected to the upper end of the lifting column 202. A top bracket 206 is fixedly installed on the abutment plate 204 of the lifting column 202. A top column 207 is fixedly connected to the upper surface of the top bracket 206. The workpiece is placed in the lower mold 5. After the top block 203 inside is in place, the first hydraulic cylinder 8 is activated to lower its hydraulic plate 9, causing the upper mold at the bottom of the hydraulic plate 9 to press down on the workpiece in the lower mold 5. The top block 203 and the four top pillars 207 move downward under pressure, compressing the spring 205. When the workpiece is stamped into a battery cover, as the hydraulic plate 9 is raised, the top block 203 and the four top pillars 207 are raised under the action of the spring 205, thereby lifting the battery cover in the lower mold 5, making it easier to demold the formed battery cover.

[0037] The removal mechanism 3 includes a fixed base 301 and a slide rod 302. The slide rod 302 is fixedly connected to the fixed base 301. A movable base 304 is slidably connected to the slide rod 302. A mounting base 305 is fixedly connected to the movable base 304. A second cylinder 306 is fixedly connected to the mounting base 305. A fixed plate 307 is fixedly connected to the telescopic end of the second cylinder 306. A third cylinder 308 is fixedly connected to the fixed plate 307. A fixed frame 309 is fixedly connected to the telescopic end of the third cylinder 308. A first clamping block 310 is provided on the side of the fixed frame 309. A first cylinder 303 is fixedly connected to the fixed base 301. The mounting base 305 is fixedly connected to the telescopic end of the first cylinder 303. When the battery cover is removed by the top mold mechanism... After the first cylinder 306 is lifted, the second cylinder 306 is activated to raise the fixing plate 307 to a suitable position. Then, the third cylinder 308 is activated to push the fixing frame 309 closer to the battery cover, so that the battery cover is clamped by the clamping blocks on both sides. After completion, the second cylinder 306 lifts the fixing plate 307 again, so that the battery cover is completely separated from the lower mold 5. The first cylinder 303 is activated to push the mounting base 305 to move along the slide bar 302, so that the battery cover is clamped and moved above the discharge groove 316. At this time, the third cylinder 308 drives the clamping blocks to reset, so that the battery cover falls onto the discharge groove 316 for discharge. The process does not require manual intervention and can realize automated demolding and discharge, improving the production efficiency of battery covers for three-wheeled electric vehicles.

[0038] A spring groove 208 is provided on the base 10. The limiting cylinder 201 is fixedly connected inside the spring groove 208. The upper end of the spring 205 abuts against the bottom of the abutment plate 204, and the lower end of the spring 205 abuts against the inside of the spring groove 208. The abutment plate 204 facilitates the spring 205 to lift the lifting column 202, thereby causing its top block 203 to lift the formed battery cover from the lower mold 5.

[0039] The bottom of the hydraulic plate 9 is fixedly connected to the upper mold. The bottom of the lower mold 5 has a first through hole 209 and a second through hole 210. The top column 207 passes through the interior of the second through hole 210. The first through hole 209 allows the top block 203 to be raised and lowered, and the second through hole 210 allows the top column 207 to be moved up and down.

[0040] There are four top pillars 207, which are fixedly connected to the four corners of the upper surface of the top frame 206. By setting the four top pillars 207, the four corners of the battery cover can be lifted, which facilitates the quick demolding of the battery cover.

[0041] The movable seat 304 has a sliding hole 311, and the sliding rod 302 passes through the interior of the sliding hole 311. The fixed seat 301 is fixedly connected to the upper surface of the base 10. The bottom of the fixed plate 307 is fixedly connected to a first limiting rod 313. The mounting seat 305 has a first limiting hole 312, and the lower end of the first limiting rod 313 passes through the interior of the first limiting hole 312. There are two first limiting rods 313, and the two first limiting rods 313 are respectively fixedly connected to the bottom ends of the fixed plate 307. The setting of the first limiting rod 313 and the first limiting hole 312 can play a limiting and guiding role for the fixed plate 307, so that the fixed plate 307 can be stably raised and lowered under the action of the second cylinder 306.

[0042] The fixed plate 307 has a second limiting hole 314, and a second limiting rod 315 is inserted into the second limiting hole 314. The second limiting rod 315 is fixedly connected to the fixed frame 309. The base 10 has a discharge groove 316. The setting of the second limiting hole 314 and the second limiting rod 315 can play a limiting and guiding role for the fixed frame 309, so that the fixed frame 309 can move stably left and right under the action of the third cylinder 308.

[0043] Working principle: After the workpiece is placed on the top block 203 inside the lower mold 5, the first hydraulic cylinder 8 is activated to lower the hydraulic plate 9, causing the upper mold at the bottom of the hydraulic plate 9 to press down on the workpiece in the lower mold 5. Under pressure, the top block 203 and the four top pillars 207 move downward, compressing the spring 205. When the workpiece is stamped into a battery cover, as the hydraulic plate 9 rises, the top block 203 and the four top pillars 207 are lifted by the spring 205, thereby lifting the battery cover in the lower mold 5, facilitating demolding of the formed battery cover. After the battery cover is lifted by the top mold mechanism 2, the second cylinder 306 is activated to fix the plate. 307 rises to the appropriate position, and then the third cylinder 308 is activated to push the fixing frame 309 closer to the battery cover, so that the battery cover is clamped by the clamping blocks on both sides. After completion, the second cylinder 306 lifts the fixing plate 307 again, so that the battery cover is completely separated from the lower mold 5. The first cylinder 303 is activated to push the mounting base 305 to move along the slide bar 302, so that the battery cover is clamped and moved above the discharge groove 316. At this time, the third cylinder 308 drives the clamping blocks to reset, so that the battery cover falls into the discharge groove 316 for discharge. The process does not require manual intervention and can realize automated demolding and discharge, improving the production efficiency of battery covers for three-wheeled electric vehicles.

[0044] Please see Figure 6-7 Based on the above embodiments, in another embodiment of the present invention, an adjustment mechanism 4 is provided on the fixed frame 309. The adjustment mechanism 4 includes a bearing 401 and a bidirectional screw 402. The bearing 401 is fixedly connected to the fixed frame 309, and the bidirectional screw 402 is fixedly connected to the inner wall of the inner ring of the bearing 401. The bidirectional screw 402 can rotate inside the fixed frame 309 by the arrangement of the bearing 401.

[0045] The first clamping block 310 is threaded onto the bidirectional screw 402. The first clamping block 310 has an internal threaded hole 404. The bidirectional screw 402 is threaded into the internal threaded hole 404. The bidirectional screw 402 is threaded onto the second clamping block 403. A throttle 405 is fixedly connected to the bidirectional screw 402. By rotating the throttle 405, the operator can drive the bidirectional screw 402 to rotate, thereby adjusting the distance between the first clamping block 310 and the second clamping block 403, which is convenient for clamping battery covers of different sizes.

[0046] Working principle: By rotating the handle 405, the operator can drive the bidirectional screw 402 to rotate, thereby adjusting the distance between the first clamping block 310 and the second clamping block 403. This allows the first clamping block 310 and the second clamping block 403 to abut against the appropriate clamping points on the battery cover, making the battery cover more stable when demolding and removing it. This avoids the problem of unstable clamping and falling of the battery cover, and facilitates clamping battery covers of different sizes.

[0047] Please see Figure 2 , 3 8. Based on the above embodiments, in another embodiment of the present invention, a storage groove 11 is provided on the base 10, and a limiting groove 12 is provided on the inner wall of the storage groove 11. A limiting block 16 is slidably connected inside the limiting groove 12, and the limiting block 16 is fixedly connected to the side wall of the base 10. The storage groove 11 can be conveniently stored on the body 1.

[0048] The storage slot 11 has a groove 13 on its inner bottom wall. A second hydraulic cylinder 14 is fixedly connected inside the groove 13. A connecting plate 15 is fixedly connected to the telescopic end of the second hydraulic cylinder 14. The connecting plate 15 is fixedly connected to the bottom of the base 10. By activating the second hydraulic cylinder 14, the connecting plate 15 can be pushed to move the base 10, making it easier to move the base 10 out of the hydraulic plate 9, so that the staff can easily maintain the structural components on the base 10.

[0049] Working principle: When it is necessary to maintain and repair the structural components on the base 10, the second hydraulic cylinder 14 can be activated to push the connecting plate 15 to move the base 10 along the direction of the limiting groove 12, so that the base 10 can be moved out of the hydraulic plate 9. This avoids the inconvenience of maintenance and repair of the structural components on the base 10 under the hydraulic plate 9, and further improves the practicality of the stamping forming machine.
