Description

Technical Field

[0001] This utility model belongs to the field of hardware processing technology, specifically relating to a punching device for hardware sheets. Background Technology

[0002] Sheet metal refers to standard-sized, flat, rectangular building material panels used in the construction industry for wall, ceiling, or floor components. It also often refers to metal sheets produced by forging, rolling, or casting. Sheet metal is categorized into thin, medium, thick, and extra-thick sheets, typically made into standard-sized, flat, rectangular building material panels. Sheet metal processing includes sheet cutting and punching, among other things.

[0003] Currently, in the production process of metal sheet, it is necessary to punch holes in the sheet. However, the punching equipment cannot guarantee the stability of the metal sheet during processing, which can easily affect the processing accuracy of the sheet. Furthermore, the punching device lacks a buffer mechanism, which can lead to the punch head breaking off due to rapid contact with the sheet without any buffer space during the punching process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a punching device for metal sheets. This addresses the problem mentioned in the background art that, in the current process of metal sheet production, punching is required for the sheet, but the punching device cannot guarantee the stability of the metal sheet during processing, which can easily affect the processing accuracy of the sheet. Furthermore, the punching device lacks a buffer mechanism, which can lead to the punch head breaking off due to rapid contact with the sheet without buffer space during the punching process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a punching device for metal sheets, comprising a processing table, with guide rods symmetrically slidably connected to both sides inside the processing table, a limit plate fixedly connected to one end of each guide rod, an L-shaped positioning seat fixedly connected to the other end of each guide rod, a spring fixedly connected between the L-shaped positioning seat and the processing table, an electric push rod fixedly connected to the top of the L-shaped positioning seat, a clamping block fixedly connected to the output end of the electric push rod, a support base fixedly connected to one side of the top of the processing table, a contact sensor fixedly connected to one side of the support base, a bracket fixedly connected to the top of the processing table, and a punching mechanism provided on the top of the bracket.

[0006] Preferably, a power distribution box and a controller are fixedly connected to one side of the bottom of the processing table.

[0007] Preferably, a handle is fixedly connected to one end of the limiting plate.

[0008] Preferably, the inner side of the L-shaped positioning seat is symmetrically provided with inclined sides, and the inner side of the L-shaped positioning seat is rotatably connected with rollers.

[0009] Preferably, the punching mechanism includes a hydraulic push cylinder, the output end of which is fixedly connected to a punching head, a fixed seat is symmetrically fixedly connected to the upper end of one side of the punching head, a limit rod is fixedly connected to the top of the fixed seat, and a damping mechanism is symmetrically arranged at the lower end of one side of the punching head.

[0010] Preferably, the limiting rod is slidably connected inside the bracket, and a limiting plate is fixedly connected to the top of the limiting rod.

[0011] Preferably, the damping mechanism includes a buffer box, a damping spring is fixedly connected to the upper end of the buffer box, a buffer rod is fixedly connected to the bottom of the damping spring, and a buffer seat is fixedly connected to the bottom of the buffer rod.

[0012] Preferably, the buffer rod is slidably connected inside the buffer box, and a buffer pad is fixedly connected to the bottom of the buffer seat.

[0013] Compared with the prior art, this utility model provides a punching device for metal sheets, which has the following beneficial effects:

[0014] 1. This utility model provides a punching device for metal sheets. During use, the metal sheet is placed on the top of the processing table and pushed forward. The front end of the metal sheet contacts the inclined edge inside the L-shaped positioning seat, causing the L-shaped positioning seat to be pressurized and the spring to move outward. Then, the metal sheet contacts the surface of the roller. Since the roller is rotatably connected, the metal sheet can be smoothly pushed into the next L-shaped positioning seat. Finally, the metal sheet contacts the surface of the contact sensor, generating a signal to control the electric push rod to push the clamping block to squeeze and position the metal sheet. This left-right clamping and top positioning method effectively improves the stability of the metal sheet during the punching process, thereby improving the processing accuracy of the sheet.

[0015] 2. By setting a damping mechanism, during the punching process of the punching equipment, the punching head first contacts the surface of the metal sheet with the buffer seat. The buffer pad located at the bottom of the buffer seat can initially play a buffering role. Then, the buffer seat drives the buffer rod to move upward to compress the damping spring inside the buffer box. Since the damping mechanism is composed of a damper, the vibration amplitude is reduced, thereby improving the buffering effect.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a scientific and reasonable structure, is safe and convenient to use, and provides great help to people. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1-6This utility model provides a technical solution: a punching device for metal sheets, including a processing table 1. Guide rods 4 are symmetrically slidably connected to both sides inside the processing table 1. One end of each guide rod 4 is fixedly connected to a limit plate 5, and the other end is fixedly connected to an L-shaped positioning seat 7. A spring 10 is fixedly connected between the L-shaped positioning seat 7 and the processing table 1. An electric push rod 11 is fixedly connected to the top of the L-shaped positioning seat 7, and a clamping block 12 is fixedly connected to the output end of the electric push rod 11. A support seat 13 is fixedly connected to one side of the top of the processing table 1, and a contact sensor 14 is fixedly connected to one side of the support seat 13. A bracket 15 is fixedly connected to the top of the processing table 1. The top of the 15 is equipped with a punching mechanism. The front end of the metal sheet contacts the inclined edge 8 inside the L-shaped positioning seat 7, so that the L-shaped positioning seat 7 is pressed and the compression spring 10 moves outward. Then the metal sheet will contact the surface of the roller 9. Since the roller 9 is rotatably connected, the metal sheet can be smoothly pushed into the next L-shaped positioning seat 7. Finally, the metal sheet will contact the surface of the contact sensor 14, thereby generating a signal to control the electric push rod 11 to push the clamping block 12 to squeeze and position the metal sheet. In this way, the stability of the metal sheet during the punching process can be effectively improved by using left and right clamping and top positioning, so as to improve the processing accuracy of the sheet.

[0027] In this utility model, preferably, a distribution box 2 and a controller 3 are fixedly connected to one side of the bottom of the processing table 1, a handle 6 is fixedly connected to one end of the limiting plate 5, a symmetrically provided inclined side 8 is provided on the inner side of the L-shaped positioning seat 7, a roller 9 is rotatably connected to the inner side of the L-shaped positioning seat 7, the punching mechanism includes a hydraulic push cylinder 16, a punching head 17 is fixedly connected to the output end of the hydraulic push cylinder 16, a fixed seat 18 is symmetrically fixedly connected to the upper end of one side of the punching head 17, a limiting rod 19 is fixedly connected to the top of the fixed seat 18, and a damping mechanism is symmetrically provided at the lower end of one side of the punching head 17.

[0028] In this utility model, preferably, the limiting rod 19 is slidably connected inside the bracket 15, the top of the limiting rod 19 is fixedly connected to the limiting plate 20, the damping mechanism includes a buffer box 21, the upper end of the buffer box 21 is fixedly connected to a damping spring 22, the bottom of the damping spring 22 is fixedly connected to a buffer rod 23, the bottom of the buffer rod 23 is fixedly connected to a buffer seat 24, the buffer rod 23 is slidably connected inside the buffer box 21, and the bottom of the buffer seat 24 is fixedly connected to a buffer pad 25.

[0029] The working principle and usage process of this utility model are as follows: During use, a metal sheet is placed on the processing table 1, with its front end contacting the inclined edge 8 inside the L-shaped positioning seat 7. When the L-shaped positioning seat 7 is subjected to pressure, it compresses the spring 10 and moves it outward. At this time, the metal sheet will contact the surface of the roller 9. Since the roller 9 is rotatably connected, the metal sheet can be smoothly pushed into the next L-shaped positioning seat 7. During the movement, the metal sheet will contact the surface of the contact sensor 14, thereby generating a signal. This signal is received and processed by the controller 3, which then controls the electric push rod 11 to push the clamping block 12, squeezing and positioning the metal sheet. In this way, the stability of the metal sheet during the punching process can be effectively improved by using left and right clamping and top positioning, thereby improving the processing accuracy of the sheet. During the punching process, the punching mechanism plays a role, including a hydraulic push cylinder 16. The output end is fixedly connected to a punching head 17. A fixed seat 18 is symmetrically fixedly connected to the upper end of one side of the punching head 17. A limit rod 19 is fixedly connected to the top of the fixed seat 18. A damping mechanism is symmetrically arranged at the lower end of one side of the punching head 17, including a buffer box 21, a damping spring 22, a buffer rod 23, and a buffer seat 24. When the metal sheet is pushed to the punching position, the hydraulic push cylinder 16 is controlled to make the punching head 17 punch the metal sheet and complete the punching operation. During this process, the damping mechanism can play a shock absorption role and ensure the stability of the punching process. In addition, for convenient operation and maintenance, a power distribution box 2 and a controller 3 are fixedly connected to one side of the bottom of the processing table 1, and a handle 6 is fixedly connected to one end of the limit plate 5 to facilitate the operator to adjust the limit position. In summary, this metal sheet punching equipment achieves efficient and high-precision sheet processing through a series of precise positioning, clamping, and punching operations.
