Description

Technical Field

[0001] This application relates to workpiece processing, specifically a rapid stamping equipment for irregularly shaped workpieces. Background Technology

[0002] In the industrial manufacturing sector, irregularly shaped workpieces (such as automotive irregularly shaped connectors, electronic precision irregularly shaped parts, and irregular medical device accessories) have complex structures (often containing curved surfaces, irregular holes, and asymmetrical contours). Their forming processes demand extremely high precision, efficiency, and adaptability. Stamping, with its high forming speed and material utilization, has become a core technology for the mass production of irregularly shaped workpieces. Existing stamping equipment for irregularly shaped workpieces is mostly based on a "fixed mold + single power" model. Its core structure includes a stamping power module (hydraulic / pneumatic drive), a fixed cavity mold, and a sheet metal positioning mechanism. Through the cooperation of the punch and the mold, metal or non-metal sheets are pressed into a pre-set irregular structure. However, this type of equipment has significant technical challenges in practical applications.

[0003] Due to the complex structures of irregularly shaped workpieces, such as curved surfaces, irregular holes, and asymmetrical contours, the positioning stability of these workpieces has always been a core challenge in stamping. The positioning mechanisms of existing equipment are mostly based on rigid planar clamping or single-point limiting designs, which cannot adapt to the irregular surfaces of workpieces. Planar clamping can only achieve partial contact with curved workpieces, and uneven distribution of clamping force can easily lead to "virtual clamping" of the workpiece. Single-point limiting, on the other hand, has only one point of force application, and the workpiece is prone to slight displacement due to axial impact force during stamping. This displacement directly triggers a chain reaction of problems. At the same time, frequent manual adjustments severely slow down the production pace and restrict the efficiency of mass production. Utility Model Content

[0004] In view of the aforementioned related technologies, the purpose of this application is to provide a rapid stamping equipment for irregularly shaped workpieces, which solves the problem of insufficient positioning stability for irregularly shaped workpieces. Existing equipment has weak limiting ability for irregularly shaped workpieces, and is prone to displacement due to force during stamping, resulting in out-of-tolerance machining dimensions, contour deformation, and low pass rate.

[0005] This application provides a rapid stamping equipment for irregularly shaped workpieces, employing the following technical solution: It includes a main body, with a fixed plate fixedly connected to the top edge of the main body. A crossbar is slidably connected to the middle of the fixed plate. A handle piece is fixedly connected to one end of the crossbar, and a hook piece is rotatably connected to the top of the handle piece. A grooved plate is fixedly connected to the top of the fixed plate, the grooved plate being inclined upwards at a 45-degree angle, and having multiple clockwise slots on its upper surface, with the hook pieces adapted to it. A side plate is fixedly connected to the middle of the outer wall of the crossbar, with a first telescopic spring fixedly connected to one side of the side plate, and the other end of the first telescopic spring fixedly connected to the fixed plate. A wide-mouth support rod is fixedly connected to the end of the crossbar away from the handle piece. The top of the wide-mouth support rod has two through-slots, and a sliding block is slidably connected to each slot. One end of one sliding block is fixedly connected to a first gripper frame, and the other end of the sliding block is fixedly connected to a second gripper frame. The middle of the first gripper frame has a slot adapted to the second gripper frame, and the two interlock. By adopting the above technical solution, through the arrangement of the hook claw plate, slotted plate, wide-mouth support rod, sliding block, first gripper frame, and second gripper frame, during use, a person can push the handle plate, causing the crossbar to move horizontally. The first telescopic spring stretches as the crossbar moves, thus storing force. Then, the person pulls the hook claw plate, causing it to bend and hook onto a slot in the slotted plate, locking the crossbar in place. Simultaneously, the wide-mouth support rod moves forward with the crossbar, pushing the first and second gripper frames. The first and second gripper frames interlock and close together as they are pushed, thus clamping the arc-shaped clamping plate. This achieves rapid clamping and locking of irregularly shaped workpieces, preventing them from shifting during stamping due to force, ensuring the processing quality of irregularly shaped workpieces. Furthermore, the operation is simple and easy to learn, and the clamping and locking mechanism can accommodate irregularly shaped workpieces of various sizes and shapes.

[0006] Preferably, a processing table is fixedly connected to the middle of the main body, and a plurality of second telescopic springs arranged in a ring array are fixedly connected to the inner wall of the processing table.

[0007] By adopting the above technical solution and utilizing the characteristics of springs, the initial positioning and clamping of irregularly shaped workpieces can be achieved.

[0008] Preferably, one end of each of the plurality of second telescopic springs is fixedly connected to an arc-shaped support piece, the plurality of arc-shaped support pieces are arranged in a ring array to form a circular shape, and a push block is fixed to one bottom side of each spring.

[0009] By adopting the above technical solution, the bottom of the irregular workpiece is reinforced so that the middle part of the workpiece is not affected during stamping.

[0010] Preferably, a plurality of support rods are slidably connected to the middle of the processing table, and the bottom ends of the plurality of support rods are fixedly connected to a common base plate.

[0011] By adopting the above technical solution, the weight-adding components can be placed or fixed, thereby facilitating the repositioning of the support rod.

[0012] Preferably, the bottom of the base plate is provided with weighted sandbags.

[0013] By adopting the above technical solution, when it is necessary to remove irregularly shaped workpieces, a person pushes the support rod up and down to lift the workpiece.

[0014] Preferably, the top of the main body is provided with a collection box, and the collection box is fixed with limiting pieces on both sides, and the collection box is attached to one side of the processing table.

[0015] By adopting the above technical solution, it is convenient to pick up the collection box and prevent the collection box from falling out of the device.

[0016] Preferably, a mounting bracket is fixedly connected to the top edge of the main body, and an electric telescopic rod is fixedly connected to the top of the mounting bracket.

[0017] By adopting the above technical solution, rapid stamping and processing of irregularly shaped workpieces can be achieved.

[0018] Preferably, the output shaft of the electric telescopic rod is fixedly connected to a stamping head, and the stamping head corresponds to the center of the processing table.

[0019] By adopting the above technical solution, the middle part of the irregular workpiece is stamped to quickly remove the uneven edges of the irregular shape.

[0020] In summary, this application includes at least one of the following beneficial technical effects: This rapid stamping equipment for irregularly shaped workpieces, through the arrangement of hook claw plates, slotted plates, wide-mouth support rods, sliding rod blocks, first gripper frames, and second gripper frames, allows for operation by pushing a handle plate, which moves a crossbar. A first telescopic spring stretches as the crossbar moves, storing energy. The hook claw plate is then pulled, bending and hooking onto a slot in the slotted plate, locking the crossbar in place. Simultaneously, the wide-mouth support rod moves forward with the crossbar, pushing the first and second gripper frames. These frames interlock and converge, clamping the arc-shaped workpiece and preventing displacement during stamping, thus ensuring processing quality. The equipment is simple to operate and adaptable to various sizes and shapes of irregularly shaped workpieces.

[0021] This rapid stamping equipment for irregularly shaped workpieces, through the arrangement of a support rod, a weighted sandbag, a second telescopic spring, arc-shaped holding plates, and a collection box, allows irregularly shaped workpieces to be inserted between multiple arc-shaped holding plates during use. Simultaneously, the elasticity of the second telescopic spring causes a pusher block on one side of the arc-shaped holding plate to hold the bottom of the irregularly shaped workpiece, thus achieving initial positioning. When it is necessary to remove the irregularly shaped workpiece, the operator simply pushes the support rod up and down, lifting the workpiece so that it slides off the processing table and falls into the collection box. This device can adapt to holding the outer surface of irregularly shaped workpieces, provide initial positioning, and allow for rapid workpiece collection by the operator pushing the support rod.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: A rapid stamping equipment for irregularly shaped workpieces, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The device includes a main body 1, a fixed plate 2 fixedly connected to the top edge of the main body 1, a crossbar 3 slidably connected to the middle of the fixed plate 2, a handle piece 4 fixedly connected to one end of the crossbar 3, a hook piece 5 rotatably connected to the top of the handle piece 4, a groove plate 6 fixedly connected to the top of the fixed plate 2, the groove plate 6 being inclined upwards at a 45-degree angle, and having multiple clockwise slots on its upper surface, with the hook piece 5 fitting into them; a side plate 7 fixedly connected to the middle of the outer wall of the crossbar 3, and a first telescopic spring 8 fixedly connected to one side of the side plate 7; and the first telescopic spring 8... The other end of the compression spring 8 is fixedly connected to the fixed plate 2. The end of the crossbar 3 away from the handle plate 4 is fixedly connected to a wide-mouth support rod 9. The top of the wide-mouth support rod 9 has two through-slots, and each of the two slots has a sliding block 10 slidably connected to it. One end of one sliding block 10 is fixedly connected to a first gripper frame 11, and the other end of the other sliding block 10 is fixedly connected to a second gripper frame 12. The first gripper frame 11 has a slot in the middle that matches the second gripper frame 12, and the two interlock with each other. The crossbar is connected to the hook plate 5, the slot plate 6, and the wide-mouth support rod 9. The arrangement of the support rod 9, sliding block 10, first gripper frame 11, and second gripper frame 12 allows for operation by pushing the handle plate 4, which in turn moves the crossbar 3. The first telescopic spring 8 stretches as the crossbar 3 moves, storing energy. Then, the hook plate 5 is pulled, bending and hooking onto a slot in the groove plate 6, locking the crossbar 3 in place. Simultaneously, the wide-mouth support rod 9 moves forward with the crossbar 3, thus securing the first... The first gripper frame 11 and the second gripper frame 12 are pushed simultaneously. As the first gripper frame 11 and the second gripper frame 12 are pushed, they interlock and move closer together, thereby clamping the arc-shaped clamping piece 15. This achieves the goal of quickly clamping and locking irregularly shaped workpieces, preventing them from shifting due to force during the stamping process, thus ensuring the processing quality of irregularly shaped workpieces. The operation is simple and easy to learn, and the clamping and locking can adapt to irregularly shaped workpieces of various sizes and shapes.

[0026] Example 2: A rapid stamping equipment for irregularly shaped workpieces, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The main body 1 includes a processing table 13 fixedly connected to its center. Multiple second telescopic springs 14 arranged in a circular array are fixedly connected to the inner wall of the processing table 13. One end of each of the multiple second telescopic springs 14 is fixedly connected to an arc-shaped supporting plate 15, which, arranged in a circular array, form a circle. A push block is fixed to the bottom of each arc-shaped supporting plate 15 on one side. Multiple support rods 16 are slidably connected to the center of the processing table 13. The bottom ends of the multiple support rods 16 are fixedly connected to a common base plate 17. A weighted sandbag 18 is provided at the bottom of the base plate 17. A collection box 19 is provided at the top of the main body 1. Limiting plates are fixed to both sides of the collection box 19, and the collection box 19 is attached to one side of the processing table 13. A mounting bracket 20 is fixedly connected to the top edge of the main body 1. An electric telescopic rod 21 is fixedly connected to the top of the mounting bracket 20. A stamping head 22 is fixedly connected to the output shaft of the electric telescopic rod 21. The impact head 22 corresponds to the middle of the processing table 13. Through the arrangement of the support rod 16, the weighted sandbag 18, the second telescopic spring 14, the arc-shaped support plate 15, and the collection box 19, irregularly shaped workpieces can be inserted between multiple arc-shaped support plates 15 during use. The elastic force of the second telescopic spring 14 causes the bottom push block on one side of the arc-shaped support plate 15 to support the bottom of the irregularly shaped workpiece, thereby achieving the initial positioning of the irregularly shaped workpiece. At the same time, when it is necessary to remove the irregularly shaped workpiece, the person pushes the support rod 16 up and down, causing the support rod 16 to lift the irregularly shaped workpiece, so that the irregularly shaped workpiece slides out of the processing table 13 and falls into the collection box 19. This device can adapt to the outer surface of irregularly shaped workpieces and can perform initial positioning of irregularly shaped workpieces. At the same time, when the person pushes the support rod 16, the support rod 16 lifts the irregularly shaped workpiece and collects it, thereby achieving the purpose of quickly collecting workpieces.

[0027] The implementation principle of this application embodiment is as follows: First, the collection box 19 is placed on top of the main body 1, so that the collection box 19 is in contact with the processing table 13. Then, the irregularly shaped workpiece to be processed is placed on top of the processing table 13. At the same time, the irregularly shaped workpiece is inserted between multiple arc-shaped holding plates 15, and the elastic force of the second telescopic spring 14 is used to push the bottom of one side of the arc-shaped holding plate 15 to hold the bottom of the irregularly shaped workpiece, thereby achieving the initial positioning of the irregularly shaped workpiece. At the same time, when it is necessary to remove the irregularly shaped workpiece, the person pushes the support rod 16 up and down, so that the support rod 16 lifts the irregularly shaped workpiece, so that the irregularly shaped workpiece slides off the processing table 13 and falls into the collection box 19. After the person releases the support rod 16, the weight of the sandbag 18 at the bottom of the base plate 17 resets the support rod 16. Then the person pushes the handle plate 4. During the movement of the handle plate 4, the crossbar 3 is driven to move horizontally. The first telescopic spring 8 is stretched as the crossbar 3 moves to store force. Then, the person pulls the hook plate 5, and after bending, the hook plate 5 hooks onto a slot in the slot plate 6 to lock the crossbar 3 which has changed position. At the same time, the wide-mouth support rod 9 moves forward as the crossbar 3 moves, so that the wide-mouth support rod 9 pushes the first gripper frame 11 and the second gripper frame 12 simultaneously. The first gripper frame 11 and the second gripper frame 12 interlock and come closer together as they are pushed, thereby clamping the arc-shaped clamping plate 15. The two sliding blocks 10 slide in the two sliding grooves of the wide-mouth support rod 9, thereby providing a limit for the first gripper frame 11 and the second gripper frame 12.
