Technical Field
[0001] This utility model relates to the field of mechanical processing equipment technology, specifically to a punching device for mechanical parts equipped with reciprocating alternating processing. Background Technology
[0002] Punching is a common processing technique in the machining of mechanical parts. With the continuous development of industry, the requirements for the precision, efficiency and diversity of mechanical parts are getting higher and higher. Many mechanical products, such as automotive parts, electronic equipment housings, and metal furniture, need to be punched to meet various needs such as assembly, heat dissipation, weight reduction or appearance. Traditional punching equipment is mostly a single-station, single-processing mode. When faced with large-scale, high-precision production tasks, some limitations have been gradually exposed.

[0014] Preferably, the centers of the first and second limiting rings are aligned with the center of the circular hole on the inner wall of the mounting box.
[0015] By adopting the above technical solution and aligning limit ring one and limit ring two, the displacement accuracy of the displacement table pushing the equipment is improved.

[0018] Preferably, the stamping limiting component includes:
[0019] A stamping template is installed at the output end of the stamping column.
[0020] A limiting clamp is installed inside the processing table, and the limiting clamp consists of a rectangular plate and two U-shaped sliding plates.

[0030] Compared with the prior art, the beneficial effects of this utility model are: it is equipped with a punching device for mechanical parts with reciprocating alternating processing.
[0031] 1. The device is equipped with a displacement stage installed perpendicular to the first and second stamping columns, allowing the first and second stamping columns to reciprocate up and down. The corresponding workpieces are clamped by the first and second limiting clamps, which are positioned vertically. As the first and second stamping columns reciprocate up and down, the workpieces are punched. This achieves reciprocating alternating processing. Compared with traditional single-station single-punching equipment, there is no need to stop processing for complex repositioning and clamping operations after each punching, which greatly reduces the idle time during processing and significantly shortens the overall processing cycle of the parts. When mass-producing thin metal sheet parts with multiple punches, the processing efficiency can be increased several times.
[0032] 2. By using stamping die one in conjunction with limiting clamping plate one, and stamping die two in conjunction with limiting clamping plate two, the number of working times and time of stamping die one and stamping die two are halved. This reduces the risk of rapid wear of various parts of the mold due to prolonged concentrated stress. During the alternating punching process, the impact force acts on different areas of the mold in turn, allowing the mold time to release stress and self-adjust, thereby effectively reducing local fatigue damage to the mold and significantly extending the service life of the mold.

[0041] Please see Figure 1-6This utility model provides a technical solution: a punching device for mechanical parts with reciprocating alternating processing, including a mounting box 1, a limiting ring 1 2, a limiting ring 2 3, a displacement table 4, a limiting post 1 5, a stamping post 1 6, a stamping template 1 7, a limiting clamping plate 1 8, a positioning plate 1 9, a processing table 10, a hydraulic post 1 11, a hydraulic post 2 12, a limiting post 2 13, a stamping post 2 14, a stamping template 2 15, a limiting clamping plate 2 16, a positioning plate 2 17, and a processing table 2 18;
[0042] Among them, the mounting box 1 is configured as a rectangular box structure, and the interior of the mounting box 1 is provided with a through chamber;
[0043] The stamping column 6 has its output end penetrating the top of the mounting box 1;
[0044] The stamping column 14 has its output end penetrating the bottom of the mounting box 1.
[0045] Both the upper and lower walls of the chamber of the mounting box 1 have circular holes. A second limiting ring 3 is installed on the upper wall of the chamber, and a first limiting ring 2 is installed on the lower wall. The bottom end of the second limiting ring 3 is slidably connected to the upper opening of the displacement stage 4, and the lower opening of the displacement stage 4 is slidably connected to the upper end of the first limiting ring 2. A first limiting post 5 is installed in the upper opening of the displacement stage 4, and a second limiting post 13 is installed in the lower opening of the displacement stage 4. The upper part of the mounting box 1 is covered by liquid... Hydraulic column 11 is penetrated and installed at the lower end of machining table 10. Hydraulic column 2 12 penetrates the lower end of mounting box 1 and is installed at the upper end of machining table 2 18. The centers of limiting ring 1 2 and limiting ring 2 3 are aligned with the centers of the circular holes on the inner wall of the mounting box 1. The displacement table 4 is a circular plate structure, and the annular protrusions on the side wall of the displacement table 4 are connected to the output ends of hydraulic column 11 and hydraulic column 2 12, respectively.
[0046] The output end of the limiting post 5 is equipped with a stamping post 6, and the limiting post 5 passes through the mounting box 1 and the processing table 10, and the processing table 10 is installed on the top of the mounting box 1.
[0047] The output end of the second limiting post 13 is provided with a second stamping post 14, and the second limiting post 13 passes through the mounting box 1 and the second processing table 18. The second processing table 18 is installed at the bottom of the mounting box 1. The second processing table 18 and the first processing table 10 are respectively provided with a set of stamping limiting components. The stamping limiting components inside the first processing table 10 assist the first stamping post 6 in punching parts, and the stamping limiting components inside the second processing table 18 assist the second stamping post 14 in punching parts.
[0048] Referring to the attached diagrams in the instruction manual Figure 1-6As shown, the machining tables 10 and 18, installed on the upper and lower parts of the mounting box 1, provide a platform for alternating up-and-down punching operations. A sealing plate is installed on the surface of the through-hole of the chamber of the mounting box 1, as shown. Figure 1 As shown, hydraulic cylinders 11 and 12, installed inside the mounting box 1, operate alternately. The alternating operation of hydraulic cylinders 11 and 12 enables the displacement table 4 to reciprocate up and down inside the mounting box 1. The upper circular opening of the displacement table 4 is slidably connected to the limiting ring 3, and the lower circular opening is slidably connected to the limiting ring 2, maintaining the stability of the displacement table 4's vertical movement. During the upward movement of the displacement table 4, the stamping cylinder 6, located at the upper end of the displacement table 4, synchronously moves and pushes the stamping template 7 to perform the first stage stamping of the workpiece held by the limiting clamping plate 8. Simultaneously, the displacement table 4 rises and stops when the stamping template 7 contacts the limiting clamping plate 8. After the stamping column 16 pushes the stamping template 17 for stamping, the stamping column 16 and the displacement table 4 are reset in sequence. When the displacement table 4 descends and pushes the stamping column 24 and the stamping template 25 to process the workpiece below, the workpiece is directly inserted between the limiting clamp 18 and the stamping template 17. With the help of the external air inflation device, the residue between the limiting clamp 18 and the stamping template 17 is quickly cleaned. When the stamping template 25 contacts the limiting clamp 26, the displacement table 4 descends and stops. Then the stamping column 24 pushes the stamping template 25 for stamping. The reciprocating processing operation is achieved by the alternating operation of the stamping column 16 and the stamping column 24.
[0049] The stamping limit assembly includes:
[0050] Stamping template 7 is installed at the output end of stamping column 6;
[0051] The limiting clamp 8 is installed inside the processing table 10, and the limiting clamp 8 is composed of a rectangular plate and two U-shaped sliding plates.
[0052] Positioning plate 9 is set inside processing table 10 and is located below limiting clamping plate 8. Positioning plate 9 is penetrated by the output end of stamping column 6.
[0053] The stamping template 7, the limiting clamping plate 8, and the positioning plate 9 are installed inside the processing table 10, and the rectangular plate of the limiting clamping plate 8 has a hole through which the stamping template 7 passes.
[0054] The stamping template 215 is installed at the output end of the stamping column 214;
[0055] Limiting clamp 2 16 is installed inside processing table 2 18, and limiting clamp 2 16 is composed of a rectangular plate and two U-shaped sliding plates;
[0056] Positioning plate 2 17 is set inside processing table 2 18 and is located above limiting clamping plate 2 16. Positioning plate 2 17 is penetrated by the output end of stamping column 2 14.
[0057] The stamping template 2 15, the limiting clamping plate 2 16 and the positioning plate 2 17 are installed inside the processing table 2 18, and the rectangular plate of the limiting clamping plate 2 16 has a hole through which the stamping template 2 15 passes.
[0058] Referring to the attached diagrams in the instruction manual Figure 1-6 As shown, stamping template 17, limiting clamping plate 18, and positioning plate 19 are installed inside processing table 10, and stamping template 215, limiting clamping plate 216, and positioning plate 217 are installed on processing table 218. Figure 3 As shown, the stamping template 1 7 and stamping template 2 15 are double-layer stamping dies. During use, dies with different punching diameters can be adjusted and replaced according to the workpiece punching requirements. For replacement, the positioning plate 1 9 and positioning plate 2 17 are disassembled to facilitate adjustment and installation of stamping templates 1 7 and 2 15. Distance scales are engraved on the side walls of the limiting clamping plates 1 8 and 2 16, assisting the U-shaped sliding plate in limiting the workpiece's position on the surface of the limiting clamping plates 1 8 or 2 16. During use, the internal structure of the processing table 1 10 and the processing table 2 18 operate alternately, and stamping templates 1 7 and 2 15 are installed vertically, aligned with the centerline of stamping columns 1 6 and 2 14. Figure 3 As shown, during the continuous punching process, the structural stability of the device and the positioning accuracy of the punching head can always be maintained at a high level, ensuring the consistency of the dimensional and positional accuracy of each punch.
[0059] Working principle: When using this mechanical parts punching device with reciprocating alternating processing, the workpiece to be punched is pushed into the limiting clamp 8 and the limiting clamp 16 respectively. The position of the workpiece is restricted by the U-shaped clamps on the surface. The size and position of the stamping template 7 and the stamping template 2 15 need to be changed according to the number and position of punching. The workpiece is fixed in the punching position of the stamping template 7 and the stamping template 2 15 by moving the U-shaped clamps. The displacement table 4 is pushed alternately by the hydraulic column 11 and the hydraulic column 2 12, so that the displacement table 4 moves up and down reciprocally. In this process, the stamping columns 16 and 14, located at the upper and lower ends of the displacement table 4, perform alternating processing operations. During processing, the stamping template 7, located at the output end of the stamping column 16, comes into contact with the workpiece, and the stamping column 16 pneumatically pushes the stamping template 7 to further process the workpiece. The stamping template 15, located at the output end of the stamping column 14, processes the workpiece synchronously. Through alternating reciprocating processing operations, the force on the mold is more evenly distributed, increasing the overall practicality.
