Description

Technical Field

[0001] This utility model relates to the field of punching machine technology, specifically a punching machine for processing locking washers. Background Technology

[0002] A punching machine is a mechanical device that uses mechanical transmission and hydraulic system to punch holes in materials such as metal plates through a rapidly moving punch.

[0003] In the production of metal products, some require punching operations. The metal parts are placed on the punching equipment and punched. When the metal parts are subjected to external forces, they are prone to displacement, which affects the accuracy of punching. Therefore, it is necessary to manually fix the metal parts for punching. Currently, during the punching process, the metal parts cannot be quickly positioned and pressed, which affects the stability of the punching process.

[0004] To address the aforementioned issue of "affecting the stability of metal punching," a search revealed: Application No. CN202420384129.6 discloses a metal punching device capable of rapid positioning. This device includes a fixed plate, a reverse lead screw movably connected between two fixed plates, and a motor with its output end fixedly connected to the reverse lead screw mounted on the front end of the front fixed plate. The outer wall of the reverse lead screw is threadedly connected to two movable frames that are slidably connected to the bottom of a through groove. A positioning plate is positioned below each movable frame, and a screw movably connected to the positioning plate via a bearing is threadedly connected to the upper end of each movable frame. By bringing the movable frame close to the metal punching position and rotating the screw, the screw pushes the positioning plate downwards, pressing and fixing the metal part. This achieves rapid positioning and pressing of the metal part, thereby improving punching efficiency and stability. Furthermore, the punching debris is adsorbed onto a receiving mesh tray within the cavity for centralized collection, avoiding the need for manual cleaning and reducing work efficiency.

[0005] However, when the above-mentioned punching equipment is used, the positioning plate is pushed down by the screw to press and fix the metal parts. It is impossible to process only one metal part, which leads to a large number of repeated fixing and unfixing, thus affecting work efficiency. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] Please see Figures 1 to 5 This utility model provides a technical solution:

[0030] A punching machine for processing locking washers, comprising:

[0031] An operating table 1 is provided, with a base 2 mounted on its upper surface. The upper surface of the base 2 has a worktable 201. The two sides of the base 2 are connected to a top plate 202 via guide rods 203 and a bracket. A lifting cylinder 3 is fixedly connected to the upper surface of the top plate 202. The lower surface of the lifting cylinder 3 has a first piston rod 301 that penetrates the top plate 202 and reaches below it. A sliding plate 4 is fixedly connected to the lower surface of the first piston rod 301 via a connecting plate 302. The two ends of the sliding plate 4 are sleeved on the guide rods 203 on both sides of the base 2. A motor 5 is fixedly connected to the upper surface of the sliding plate 4. The motor is located below the connecting plate 302. An upper mold 7 is provided on the lower surface of the sliding plate 4. A lower mold 8 is provided on the upper surface of the worktable 201, which is perpendicular to the upper mold 7.

[0032] In this embodiment, the locking washer is circular. However, the punching pressure of the punching machine is relatively high, requiring a fixing device. Since the locking washer is small in size, it is inconvenient to use traditional fixing methods. Therefore, a feeding ring 801 and a limiting ring 802 are provided in the lower mold 8. The locking washer can be placed on the feeding ring 801 between the outer side of the limiting ring 802 and the lower mold 8. When the punching operation starts, the upper mold 7 descends. Since the outer diameter of the upper mold 7 is smaller than the inner diameter of the lower mold 8, the upper mold 7 can descend into the lower mold 8, so that the edge of the upper mold 7 presses against one ring of the locking washer, thereby conveniently completing the fixing without the need for additional fixing components.

[0033] Specifically, the upper mold 7 is circular, and the front end of the upper mold 7 has a notch. A punch 701 is fixedly installed in the notch, and the upper mold 7 is rotatably connected to the motor 5 through a rotating shaft 6.

[0034] In this embodiment, the lifting cylinder 3 drives the sliding plate 4 to slide up and down along the guide rod 203 to achieve lifting. At the same time, the drilling of the locking washer often requires drilling holes around the entire locking washer. Setting multiple punches 701 will reduce the fixing structure, making the locking washer easy to lift up, resulting in defective products. Alternatively, the locking washer can be manually rotated and drilled, which is inefficient and prone to accidental damage. Therefore, a motor 5 is set above the sliding plate 4, and the upper mold 7 is driven by the motor 5 to rotate, thereby achieving fast and safe drilling of the entire locking washer.

[0035] In this embodiment, material can be discharged immediately after punching is completed. The lifting cylinder 3 raises the sliding plate 4, and the second piston rod 1001 of the discharge cylinder 10 lifts the material discharge ring 801 and the limiting ring 802 (as shown in the image). Figure 5 Then the locking washer can be directly removed from the feeding ring 801, thus eliminating the step of unlocking the fixing structure and allowing the locking washer to be safely removed.

[0036] In this embodiment, when the upper mold 7 is lowered, the lower mold 8 can completely cover the edge of the upper mold 7 (e.g., ...). Figure 4 When the punching machine is punching, waste material will splash out. Therefore, the lower die 8 wraps around the upper die 7 to form an outer protective sleeve, thereby preventing waste material from splashing out and injuring the surrounding workers.

[0037] Specifically, the lower mold 8 has a feeding ring 801 inside, the upper end face of the feeding ring 801 is fixedly connected to a limit ring 802, and the lower end face is fixedly connected to a second piston rod 1001.

[0038] Specifically, the second piston rod 1001 passes through the worktable 201, the base 2 and the operating table 1 and is connected to the discharge cylinder 10.

[0039] Specifically, the outer diameter of the lower mold 8 is smaller than the inner diameter of the lower mold 8.

[0040] Specifically, a waste box 9 is installed at the front end of the workbench 201.

[0041] Specifically, the lower mold 8 has a through hole at the bottom of its front end, and the through hole is located above the waste box 9.

[0042] Specifically, the front end of the waste box 9 has a handle.

[0043] In this embodiment, the lifting cylinder 3 and the motor 5 can be automatically controlled by a PLC. A PLC (Programmable Logic Controller) is a digital computer control system specifically designed for industrial automation control. It can perform tasks such as logical operations, sequential control, timing, counting, and arithmetic operations. By automatically controlling the lifting cylinder 3 and the motor 5 through the PLC to punch holes and discharge materials, work efficiency can be improved.

[0044] The lifting cylinder 3 and the motor 5 can also be manually controlled by a switch. Manual control provides relatively good flexibility, and the operator can adjust the control strategy at any time according to the actual situation on site.

[0045] In use, the locking washer is placed on the feeding ring 801, and then the lifting cylinder 3 is activated to drive the sliding plate 4 to move downward along the guide rod 203. The upper mold 7 is placed into the lower mold 8 and the locking washer is punched by the punch 701. Then, according to the required number of holes, the upper mold 7 is rotated by the motor 5 and the rotating shaft 6 to punch holes in one ring of the locking washer. The waste generated by punching enters the waste box 9 through the through hole at the front end of the lower mold 8, waiting to be collected and processed.

[0046] After punching is completed, the sliding plate 4 and the upper mold 7 are raised, and then the discharge cylinder 10 is started to push the discharge ring 801 and the limit ring 802 upward to discharge the material, thus completing one punching process of the locking washer.

[0047] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
