DETAILED DESCRIPTION
[0030] The present application will be further described in detail below with reference to the accompanying drawings.
[0031] The present application will be further described in detail below with reference to the accompanying drawings.
[0032] The present application will be further described in detail below with reference to the accompanying drawings. Figures 1-3 , comprising: an upper die assembly 100, a lower die assembly 200, a side punching assembly 300 and a driving assembly 400.
[0033] Wherein, the upper side of the upper die assembly 100 is equipped with a stamping driving device (not shown), which is used to provide the necessary power to enable the upper die assembly 100 to be accurately depressed and reset. The lower die assembly 200 is located below the upper die assembly 100, which cooperates with the upper die assembly 100 to complete the final stamping action, while the lower die assembly 200 is the basic platform for carrying the workpiece 500, ensuring that the workpiece 500 is fixed in position during the stamping process to avoid displacement. The side punching assembly 300 is assembled between the upper die assembly 100 and the lower die assembly 200, and the side of the side punching assembly 300 towards the upper die assembly 100 is buckled with the workpiece 500. Further, the side punching assembly 300 includes: a clamping plate stopper 310, a clamping plate group 320, a stripper plate group 330, a concave die group 340, a concave die stopper 350 and a punching piece 360. Wherein, the clamping plate stopper 310 is used to limit the position of the clamping plate group 320 to ensure its stability during the stamping process. The clamping plate group 320 is arranged on one side of the clamping plate stopper 310, and the clamping plate group 320 is connected with the punching piece 360 and moves towards the inner side wall of the workpiece 500 under the action of the driving assembly 400, prompting the punching piece 360 to penetrate the inner side wall of the workpiece 500. The stripper plate group 330 is arranged on the side of the clamping plate group 320 away from the clamping plate stopper 310, specifically between the clamping plate group 320 and the concave die group 340, which supports the workpiece 500 on one hand and facilitates separation from the workpiece 500 after punching on the other hand, preventing the workpiece 500 from adhering to the stripper plate group 330 mold. The concave die group 340 is arranged on the side of the stripper plate group 330 away from the clamping plate group 320, and the concave die group 340 works with the concave die stopper 350 to tightly abut against the outer side wall of the workpiece 500 under the action of the driving assembly 400, providing a stable reaction force surface for punching. The concave die stopper 350 is arranged on the side of the concave die group 340 away from the stripper plate group 330, which is used to fix the position of the concave die group 340. One end of the punching piece 360 is fixedly assembled on the clamping plate group 320, and the other end is movably arranged on the stripper plate group 330, which is a key component for performing the punching operation. Specifically, the side punching assembly 300 is also provided with a sliding shaft 390 movably arranged on the clamping plate group 320, the stripper plate group 330 and the concave die group 340, and the two ends of the sliding shaft 390 are fixedly connected between the clamping plate stopper 310 and the concave die stopper 350, respectively. The sliding shaft 390 is used for the axial movement of the clamping plate group 320, the stripper plate group 330 and the concave die group 340 under the action of the driving assembly 400. The driving assembly 400 is assembled on the side of the lower die assembly 200 towards the side punching assembly 300, which is used to drive the side punching assembly 300 to punch the workpiece 500, and is responsible for coordinating the actions of each component.Thus, when the punch driving device drives the upper die assembly 100 to press down, the driving assembly 400 drives the inner side wall of the workpiece 500 to be clamped on the stripper plate assembly 330, providing a stable base for the punching operation. The driving assembly 400 drives the concave die assembly 340 to resist the outer side wall of the workpiece 500, providing the required reaction force for punching. At the same time, the clamping plate assembly 320 is driven to move towards the inner side wall of the workpiece 500, so that the punching element 360 punches the inner side wall of the workpiece 500. In the above punching process, the punching is realized from the inside to the outside, avoiding the generation of burrs on the inner surface of the workpiece 500, thus avoiding the burr grinding or processing not in place. Punching from the inside to the outside makes the burrs generated on the outer surface of the workpiece 500, which is more convenient for grinding or processing, and also avoids the burrs causing scratches on the product, thus reducing the impact on the product quality and reducing the cost of later processing.
[0034] In the present embodiment, with reference to Figure 7 , the stripper plate assembly 330 is provided with a protruding part 331 for clamping the workpiece 500. The protruding part 331 can better contact the inner side wall of the workpiece 500, ensuring that the workpiece 500 is tightly fitted on the stripper plate assembly 330 during the entire punching process. It helps to prevent the workpiece 500 from shifting or sliding during punching. In particular, the clamping plate baffle is provided with a positioning protrusion (not shown) for fixing the workpiece 500. The positioning protrusion can achieve good positioning effect when the workpiece 500 is clamped on the side punching assembly 300, and will not shift to affect the accuracy of the punching position.
[0035] In the present embodiment, with reference to Figures 3-4The driving assembly 400 comprises a first driving insert 410, a second driving insert 420 and a third driving insert 430. The first driving insert 410 is arranged on the side of the stripper plate set 330 away from the die set 340, and is used to place the protruding part 331 into the inner side wall of the workpiece 500. During the stamping process, the first driving insert 410 is responsible for pushing the protruding part 331 on the stripper plate set 330 to accurately enter the inner side wall of the workpiece 500, thereby ensuring that the workpiece 500 is tightly attached to the stripper plate set 330 during the stamping process. The second driving insert 420 is arranged between the die set 340 and the die block 350, and is used to push the die set 340 against the outer side wall of the workpiece 500 to provide the required reaction force for punching, ensuring the stability during punching and further reducing the deformation or deviation of the workpiece 500 caused by external force. The third driving insert 430 is arranged between the clamp block 310 and the clamp plate set 320, and is used to push the clamp plate set 320 towards the inner side wall of the workpiece 500 to cause the punch 360 to penetrate the inner side wall of the workpiece 500, ensuring the efficiency of force transmission during the punching process. Through the coordinated work of the three driving inserts, it is further ensured that each step in the punching process can be accurately performed, thereby improving the positional accuracy and dimensional consistency of the punching.
[0036] Further, with reference to Figure 4 The height of the first driving insert 410 and the second driving insert 420 is higher than the height of the third driving insert 430. Specifically, the height of the first driving insert 410 is equal to the height of the second driving insert 420. Since the first driving insert 410 and the second driving insert 420 are located higher, they act first during the stamping process, causing the protruding part 331 on the stripper plate set 330 to be tightly buckled against the inner side wall of the workpiece 500; at the same time, the die set 340 also tightly abuts against the outer side wall of the workpiece 500 to provide stable support for subsequent punching. The third driving insert 430 is slightly lower to ensure that the action of the clamp plate set 320 occurs slightly later, and the punching operation is performed only after the workpiece 500 is firmly fixed, thereby improving the accuracy of the punching.
[0037] Specifically in this embodiment, the side of the first driving insert 410 abutting against the stripper plate set 330 is provided with a first guide slope 411, the side of the second driving insert 420 abutting against the die set 340 is provided with a second guide slope 421, and the side of the third driving insert 430 abutting against the clamp plate set 320 is provided with a third guide slope 431. The three first guide slope 411, second guide slope 421 and third guide slope 431 are arranged to reduce the friction force of the abutting plate during the insertion driving process, making the action smoother and reducing the wear of the equipment and materials.
[0038] In this embodiment, with reference toFigures 2-3 The first elastic member 370 is arranged on the side of the clamp block 310 away from the clamp set 320. Specifically, the first elastic member 370 comprises a first fixed shaft 371 movably arranged in the clamp block 310 and fixedly connected with the clamp set 320, and a first spring member 372 sleeved on the end of the first fixed shaft 371 away from the clamp set 320. During the stamping process, when the third driving insert 430 pushes the clamp set 320 to punch the inner side wall of the workpiece 500, the first spring member 372 is compressed and stores energy. After the punching is completed, the third driving insert 430 is withdrawn, the first spring member 372 releases the energy, and the clamp set 320 is quickly reset to the initial position, preparing for the next punching operation, thereby improving the automation degree and work efficiency of the equipment.
[0039] In the embodiment, the second elastic member 380 is arranged on the side of the die block 350 away from the die set 340. The second elastic member 380 comprises a second fixed shaft 381 movably arranged in the die block 350 and fixedly connected with the die set 340, and a second spring member 382 sleeved on the end of the second fixed shaft 381 away from the die set 340. During the stamping process, when the second driving insert 420 pushes the die set 340 to abut against the outer side wall of the workpiece 500, the second spring member 382 is compressed and stores energy. After the punching is completed, the second driving insert 420 is withdrawn, the second spring member 382 releases the energy, and the die set 340 is quickly reset to the initial position, preparing for the next punching operation, thereby improving the automation degree and work efficiency of the equipment.
[0040] In the embodiment, referring to Figure 3 The die set 340 is provided with an avoiding hole 341 on the side facing the stripper plate set 330 for avoiding the punching of the punching member 360. The avoiding hole 341 provides sufficient space for the punching member 360 to avoid collision or interference with the die set 340 during the punching process. The avoiding hole 341 can also serve as a guide channel for the punching member 360 to ensure that the punching member 360 accurately penetrates the side wall of the workpiece 500.
[0041] In the embodiment, referring to Figures 3-6 The side punching assembly 300 is further provided with a through hole 210 penetrating the die set 340 and the lower die assembly 200 and communicating with the avoiding hole 341. The through hole 210 communicates the avoiding hole 341 and the lower die assembly 200, forming a complete waste discharge path, so that the waste (such as metal chips) generated by punching can be directly discharged through the through hole 210, avoiding the waste to be retained in the mold. At the same time, since the waste can be directly discharged through the through hole 210, the subsequent cleaning workload is reduced, and the production efficiency is improved.
[0042] Further, the lower die assembly 200 comprises a waste conduit 220 arranged in the through hole 210 and a waste box 230 arranged in communication with the through hole 210. The waste conduit 220 further guides the waste from the through hole 210 into the waste box 230, ensuring that the waste can be smoothly discharged and avoiding blockage. Specifically, the lower die assembly 200 is further provided with a lower stripper plate 240 for carrying the side punching assembly 300 and a lower clamping plate 250 arranged on the lower side of the lower stripper plate 240. After completing a punching process, a gap is generated between the lower stripper plate 240 and the lower clamping plate 250 due to the arrangement of an elastic member (not shown) therebetween, and the waste conduit 220 arranged at this gap avoids the waste from being blocked in the gap. However, when the punching process is completed, the arrangement of the elastic member causes the driving insert of the driving assembly 400 to be separated from the side punching assembly 300. The waste box 230 is used to collect the waste discharged from the through hole 210, facilitating centralized treatment. Specifically, the bottom of the waste box 230 is provided with a waste suction port 231 for connecting an external waste suction device.
[0043] The above is only used to illustrate the technical solutions of the present application and is not limited. Other modifications or equivalent replacements made by those skilled in the art to the technical solutions of the present application should be covered in the scope of the claims of the present application as long as they do not deviate from the spirit and scope of the technical solutions of the present application.
