Detailed Implementation

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1 to 3 As shown in the figure, a stamping device for producing new energy vehicle parts according to an embodiment of the present invention includes a stamping machine 1, a lifting seat 11 slidably connected to the upper part of one end of the stamping machine 1, a hydraulic telescopic rod 12 installed inside the lifting seat 11, the top end of the hydraulic telescopic rod 12 being fixedly connected to the stamping machine 1, an upper die seat 41 installed at the bottom end of the lifting seat 11, a base 2 installed at one end of the stamping machine 1 below the lifting seat 11, a second slide groove 211 opened at the top end of the base 2, an mounting plate 222 slidably connected inside the second slide groove 211, a lower die seat 4 installed at the top end of the mounting plate 222, a first slide groove 21 opened below the second slide groove 211, and a moving block 22 rotatably connected to one side of the mounting plate 222, the moving block 22 being slidably connected inside the first slide groove 21;

[0038] During the process of the hydraulic telescopic rod 12 driving the lifting seat 11 to rise and fall, the moving block 22 is driven to slide inside the first slide groove 21, thereby causing the mounting plate 222 to drive the lower mold seat 4 to move away from below the upper mold seat 41, and causing the mounting plate 222 to drive the lower mold seat 4 to rotate.

[0039] In the production of new energy vehicles, multiple components need to be assembled together. During component production, some components require stamping. During stamping, the metal sheet to be stamped is cut to the required size. Initially, the hydraulic telescopic rod 12 drives the lifting seat 11 to rise to the highest point inside the stamping machine 1. At this time, the lifting seat 11 pulls the upper die seat 41 to its highest position. (See reference...) Figure 1-2 In this state, the hydraulic telescopic rod 12 is then activated to push the lifting seat 11 downwards a certain distance. At this time, the lifting seat 11 will drive the moving block 22 to move to the middle of the base 2, and the lower mold base 4 will rotate and be in a horizontal state. (See reference...) Figure 3 In this state, a certain space is still maintained between the lower mold base 4 and the upper mold base 41. The sheared metal sheet is then placed into the lower mold base 4. After the metal sheet falls into the lower mold base 4, the hydraulic telescopic rod 12 is activated to continue pushing the lifting seat 11 downwards. The lifting seat 11 pushes the upper mold base 41 downwards. When the upper mold base 41 is pushed into the lower mold base 4, it compresses the metal sheet. The shape of the bottom of the upper mold base 41 and the shape inside the lower mold base 4 can compress the metal sheet into the desired shape. After the metal sheet is formed, the hydraulic telescopic rod 12 is activated to lift the lifting seat 11. During the lifting process, the upper mold base 11 is lifted. 41 is moved out from the inside of the lower mold base 4. After the upper mold base 41 is separated from the lower mold base 4, the lifting seat 11 will drive the moving block 22 to slide towards one side of the base 2 inside the first slide groove 21. When the moving block 22 slides to the end of the first slide groove 21, the mounting plate 222 will drive the lower mold base 4 to rotate 160°. At this time, the top opening of the lower mold base 4 will be in a downward state. At this time, the molded part inside the lower mold base 4 will fall out of the lower mold base 4 due to gravity. The workpiece collection basket is placed in advance at the position where the lower mold base 4 is flipped. The molded part that falls out of the lower mold base 4 will fall into the collection basket. Repeating the above steps can realize the automatic removal of the molded part.

[0040] like Figures 1 to 4 As shown, a first lead screw 221 is rotatably connected inside the first slide groove 21. The first lead screw 221 is threadedly connected to the moving block 22. A pulley is fixed to one end of the first lead screw 221 near the mounting plate 222. Two second gears 112 are fixed to the bottom end of the lifting seat 11. Two gears 224 are rotatably connected inside the base 2 near the second gears 112. A pulley is also fixed between the two gears 224. A belt is sleeved on the outside of the two pulleys. The two gears 224 are respectively meshed with the two second gears 112.

[0041] The second rack 112 has teeth only in its lower half, and the upper half of the second rack 112 is not meshed with the gear 224.

[0042] During the lifting process of the lifting seat 11, the moving block 22 will move. Initially, the lower mold base 4 and the upper mold base 41 are in the mold-closing state. Then, as the lifting seat 11 rises, it will drive the second gear 112 to rise. During this process, the toothless part of the second gear 112 will first pass through the gear 224. Because the second gear 112 has no teeth, it will not drive the gear 224 to rotate. Therefore, during this process, the upper mold base 41 and the lower mold base 4 separate, and the lower mold base 4 remains in its original position. When the second gear 112 continues to move upward, the toothed part contacts the gear 224. When the second rack 112 drives the gear 224 to rotate, the gear 224 drives the first lead screw 221 to rotate through the pulley and belt. At this time, the first lead screw 221 drives the moving block 22 to slide away from the gear 224 inside the first slide groove 21. The moving block 22 drives the mounting plate 222 to drag the lower mold base 4. When the lifting seat 11 moves to the highest position, the moving block 22 moves to the end of the first slide groove 21. At this time, the mounting plate 222 drives the lower mold base 4 to rotate. After the lower mold base 4 rotates, the opening faces downward. At this time, the molded part inside the lower mold base 4 can be poured out.

[0043] Next, the hydraulic telescopic rod 12 pushes the lifting seat 11 downward. At this time, the lifting seat 11 drives the gear 224 to rotate in the opposite direction through the tooth section of the second gear 112. The gear 224 drives the first lead screw 221 to rotate in the opposite direction, which can drive the moving block 22 to move towards the upper mold seat 41. During this process, the mounting plate 222 first drives the lower mold seat 4 to rotate in the opposite direction and reset. Then, driven by the moving block 22, the mounting plate 222 drives the lower mold seat 4 to move below the upper mold seat 41. During this process, there is a large space between the lower mold seat 4 and the upper mold seat 41. The rotation of the lower mold seat 4 will not interfere with the lower mold seat 4 and the lifting seat 11. After the lower mold seat 4 and the upper mold seat 41 are aligned, the tooth section of the second gear 112 separates from the gear 224, and the hydraulic telescopic rod 12 stops pushing the lifting seat 11. At this time, a new metal plate can be placed. Then, the hydraulic telescopic rod 12 can be started to continue to drive the lifting seat 11 to push the upper mold seat 41 and the lower mold seat 4 to close the mold. By continuing to run this process, the stamping can continue.

[0044] like Figures 3 to 4 As shown, two toothed plates 212 are provided on one side of the second slide groove 211, and toothed rings 223 are fixed on both sides of the mounting plate 222 near the moving block 22. The toothed rings 223 can mesh with the toothed plates 212.

[0045] During the process of moving the mounting plate 222 driven by the moving block 22, the toothed ring 223 meshes with the toothed plate 212 to drive the mounting plate 222 to rotate.

[0046] When the moving block 22 moves away from the gear 224, it causes the mounting plate 222 to move to contact the toothed plate 212. The toothed plate 212 will drive the mounting plate 222 to rotate through the toothed ring 223. When the moving block 22 drives the mounting plate 222 to reset, the mounting plate 222 can be automatically rotated in the opposite direction to reset through the action of the toothed plate 212 and the toothed ring 223. This can automatically enable the lower mold base 4 to rotate to discharge the molded part and automatically reset.

[0047] like Figures 1 to 7 As shown, a storage box 3 is provided on one side of the stamping machine 1, and a pusher 241 is provided above the storage box 3. An electric telescopic rod 24 is installed inside the base 2, and the end of the electric telescopic rod 24 is fixedly connected to the pusher 241. A top plate 32 is slidably connected inside the storage box 3. An opening is provided on one side of the top of the storage box 3, and a guide shell 31 is provided on the side of the storage box 3 near the opening.

[0048] Among them, the top plate 32 lifts the metal sheet, and the electric telescopic rod 24 drives the pusher 241 to push the metal sheet into the interior of the lower mold base 4.

[0049] Before stamping, the metal sheets to be stamped are stacked layer by layer into the storage box 3. At this time, the top plate 32 supports the metal sheets inside the storage box 3. Then, when the metal sheets need to be placed into the lower die base 4, the electric telescopic rod 24 is activated to pull the pusher 241 to move. When the pusher 241 passes over the top of the storage box 3, it will move the topmost metal sheet inside the storage box 3. The metal sheet moves out of the opening of the storage box 3 and is guided by the guide shell 31 to the direction of the lower die base 4. Then the metal sheet enters the lower die base 4. Subsequently, the electric telescopic rod 24 pushes the pusher 241 to reset. Then the top plate 32 rises up to push the metal sheet below to fill the gap, which can realize automatic loading.

[0050] like Figures 1 to 7 As shown, a lifting column 311 is fixed to the bottom of the guide shell 31, a connecting seat 313 is sleeved on the outside of the lifting column 311, a second spring 312 is fixed to the bottom of the lifting column 311, the bottom of the second spring 312 is fixedly connected to the connecting seat 313, and the bottom of the connecting seat 313 is fixedly connected to the top of the base 2.

[0051] When the lifting seat 11 pushes the upper mold seat 41 and the lower mold seat 4 to close, it may interfere with the guide shell 31. At this time, the guide shell 31 is pushed down by the lifting seat 11. The guide shell 31 pushes the lifting column 311 to squeeze the second spring 312 inside the connecting seat 313, which can achieve automatic descent. At the same time, when the lifting seat 11 rises, the elastic force of the second spring 312 pushes the guide shell 31 to automatically reset through the lifting column 311.

[0052] like Figures 1 to 6As shown, a second lead screw 33 is rotatably connected to one side of the storage box 3. A worm gear 331 is fixed to the top of the second lead screw 33. One side of the top plate 32 is threadedly connected to the second lead screw 33. A worm 332 is meshed with one side of the worm gear 331. The worm 332 is rotatably connected to one side of the storage box 3. The end of the worm 332 away from the storage box 3 is connected to a toothed sleeve 333 through a ratchet and ratchet structure. A first toothed rod 111 is fixed to the bottom of the lifting seat 11 near the storage box 3. The first toothed rod 111 can mesh with the toothed sleeve 333.

[0053] When the first rack 111 moves downward, it can drive the worm 332 to rotate through the gear sleeve 333; when the first rack 111 moves upward, it cannot drive the worm 332 to rotate through the gear sleeve 333.

[0054] During the descent of the lifting seat 11, the lower mold base 4 requires two strokes to reset. After the first stroke, the lifting seat 11 stops and waits for the lower mold base 4 to be filled with material. During the first stroke, the first toothed rod 111 does not contact the toothed sleeve 333. After the material is filled, the pusher 241 resets. At this time, the lifting seat 11 continues to move downward and enters the second stroke. During the second stroke, the lifting seat 11 drives the upper mold base 41 to press the metal sheet inside the lower mold base 4. At the same time, the lifting seat 11 drives the first toothed rod 111 to contact the toothed sleeve 333 and drive the toothed sleeve 333 to rotate one revolution. The toothed sleeve 333 drives the worm gear 332 to rotate through the ratchet and ratchet structure. The worm gear 332 drives the worm wheel 331 to rotate, which can make the second lead screw 33 rotate. At this time, the second lead screw 33 drives the top plate 32 to rise to a height that matches the thickness of the metal sheet, which can realize the automatic filling of the metal sheet inside the storage box 3 for the next filling.

[0055] When the lifting seat 11 drives the first gear 111 to rise, the gear sleeve 333 is not connected to the worm gear 332 due to the ratchet and ratchet structure, and will not drive the worm gear 332 to rotate in the opposite direction.

[0056] like Figures 1 to 6 As shown, a crank handle 334 is provided at the end of the worm gear 332 near the gear sleeve 333, and the crank handle 334 is fixedly connected to the connecting disc of the ratchet and ratchet structure.

[0057] After all the metal sheets inside the storage box 3 have been processed, the top plate 32 will be at the top of the storage box 3. Further processing requires filling the storage box 3 with new sheets. At this time, the top plate 32 needs to be reset after filling. During the filling process, the metal sheets are stacked on top of the top plate 32. At the same time, turning the crank 334 in the opposite direction can drive the second lead screw 33 to rotate in the opposite direction. At this time, the second lead screw 33 drives the top plate 32 to descend, and the metal sheets stacked on top of the top plate 32 enter the storage box 3. When the top plate 32 contacts the bottom of the storage box 3, the filling is completed. During this process, the first toothed rod 111 does not contact the toothed sleeve 333.

[0058] like Figures 1 to 9 As shown, the top of the base 2 is rotatably connected to the clamping plate 23 on both sides of the lower mold base 4 via connecting blocks. The clamping plate 23 is fixed with a telescopic column 232 on the side near the storage box 3. The telescopic column 232 has a guide groove 233 on its outer side. The telescopic column 232 is fitted with a moving rod 235. The moving rod 235 has a protrusion 236 fixed inside. The protrusion 236 is slidably connected inside the guide groove 233. A connecting plate 237 is fixed between the two moving rods 235. The bottom of the push frame 241 is fixed with a push rod 242.

[0059] When the metal sheet is pushed from inside the guide shell 31 into the lower mold base 4, it may shift, requiring correction of the metal sheet. Initially, the two clamping plates 23 are in an open state, as can be referenced. Figure 8-9 In this state, the pusher 241 drives the push rod 242 to move. The push rod 242 pushes the connecting plate 237, causing the two protrusions 236 to slide inside the guide groove 233. Under the guidance of the guide groove 233, the telescopic column 232 is driven to rotate 90°. At this time, the two clamping plates 23 are attached to both sides of the lower mold base 4. The clamping plates 23 can push the metal plate pushed by the pusher 241 towards the center line, which can play a corrective role for the metal plate.

[0060] like Figures 8 to 9 As shown, a roller 231 is rotatably connected to the top of the clamping plate 23, and the roller 231 can fit tightly against the side of the metal plate.

[0061] When the clamping plate 23 is pressed against the side of the metal plate, in order not to hinder the forward movement of the metal plate, a roller 231 is provided to allow it to roll, which can reduce the friction between the metal plate and the clamping plate 23.

[0062] like Figures 8 to 9 As shown, a first spring 234 is fixed to the end of the moving rod 235 near the clamping plate 23, and the other end of the first spring 234 is fixedly connected to the connecting block. The first spring 234 is sleeved on the outside of the telescopic column 232.

[0063] When the electric telescopic rod 24 drives the pusher 241, it will simultaneously drive the push rod 242. At this time, the connecting plate 237 loses its thrust, and the first spring 234 can push the moving rod 235 to reset. At this time, the protrusion 236 slides inside the guide groove 233, causing the telescopic column 232 to rotate 90° in the opposite direction. At this time, the clamping plate 23 can be reset by the telescopic column 232.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
