Description

Technical Field

[0001] This utility model relates to the field of punching processing technology, and in particular to a punching device for metal product processing. Background Technology

[0002] Metal products refer to various items made of metal materials, which are widely used in various fields. Metal products are usually manufactured by forging, casting, mold forming and cutting. After the basic product is formed, further fine processing is required. The most common of these processes is drilling and punching, which involves punching holes of a certain size at designated locations on the metal product to achieve its specific function.

[0003] A metal punching device is used when punching metal products. This device transmits power to the punch through a mechanical transmission mechanism, such as a crank-slider mechanism or a cam mechanism, to achieve the punching action. It is widely used in the machinery manufacturing, automobile manufacturing, electronics and electrical appliances, building decoration and hardware products industries.

[0004] In existing technology, this device utilizes a punch driven by a power mechanism to impact a metal workpiece at a certain speed and force. This causes the workpiece to undergo plastic deformation and fracture under the action of the punch and die, thereby forming the required hole. During the punching process, the cutting edge of the punch first contacts the surface of the workpiece. As the punch presses down, the cutting edge gradually cuts into the metal material. When the punching pressure reaches a certain level, the material is broken, forming a hole. Different punching pressures are required for metal materials of different thicknesses and materials. If the punching pressure is insufficient, punching cannot be completed, resulting in poor hole wall quality. A punching device with adjustable punching pressure is used, with a pressure sensor installed on the punching device to monitor the punching pressure in real time and automatically adjust the punching pressure based on feedback information. However, the die is not securely fixed during installation and use, and it will shift under the action of punching pressure, affecting the positional accuracy of punching. Utility Model Content

[0012] The door panel has handles fixedly connected to the left and right ends of the front side of the outer wall, and anti-slip sleeves are rotatably connected to the outer sides of the two handles.

[0014] An electrical wire is installed on the right side of the outer wall of the control panel, and a controller is installed at the end of the electrical wire.

[0015] As a further description of the above technical solution:

The punching action causes the mold to vibrate, and the mold transmits the force to the spring and damping rod. The spring is compressed, and its elastic deformation absorbs some of the kinetic energy generated by the mold and the punch, reducing the transmission of vibration and thus reducing the generation and propagation of noise.

[0031] 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.

[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a metal product punching device, comprising a base 1, an operating table 5 fixedly connected to the middle of the top wall of the base 1, fixed posts 10 fixedly connected to the four corners of the top wall of the base 1, a protective shell 11 fixedly connected to the top of the fixed posts 10, a mounting block 2 19 fixedly connected to the rear side of the top wall of the operating table 5, a motor 2 18 mounted at the bottom of the mounting block 2 19, a gear 1 20 fixedly connected to the output end of the motor 2 18, and the gear 1 20 rotatably connected to the top wall of the mounting block 2 19. In the middle, gears 21 are rotatably connected to the left and right sides of the top wall of mounting block 2 19. Gear 3 27 is meshed with the rear side of gear 1 20. Gear 21 on the left meshes with gear 3 27, and gear 21 on the right meshes with gear 1 20. During rotation, gear 3 27 also transmits power to gear 21 on the left, thus achieving synchronous rotation of the two gears 21. This allows the two gears 21 to rotate inward or outward as needed. A slide rail 24 is installed at the front end of the top wall of mounting block 2 19. A clamping block 13 is slidably connected to the outer wall, and the clamping block 13 meshes with the gear 21. A rubber plate 25 is installed on the inner side of the clamping block 13. The clamping block 13 can slide freely on the slide rail 24. Therefore, when the gear 21 rotates, it will drive the clamping block 13, enabling the clamping block 13 to perform clamping and opening actions. In this way, the clamping block 13 can clamp the mold and hold it in place, preventing the mold from shifting under the action of punching pressure, thus improving the positional accuracy of punching. The top wall of the mounting block 19 is equipped with a mounting plate 25. Block 14, a processing plate 12 is fixedly connected to the middle of the top wall of the operating table 5, a support column 15 is fixedly connected to the right side of the top wall of the processing plate 12, a shock-absorbing mechanism 2 is installed on the upper left side of the support column 15, the shock-absorbing mechanism 2 is used to reduce the impact force during punching, thereby reducing noise and vibration, two hinges 6 are installed on the left and right ends of the front side of the outer wall of the operating table 5, a door panel 7 is fixedly connected to the rear side of the multiple hinges 6, a handle 8 is fixedly connected to the left and right ends of the front side of the outer wall of the door panel 7, and an anti-slip sleeve 9 is rotatably connected to the outer side of the two handles 8;

[0033] Specifically, motor 218 rotates and drives gear 120. Gear 120 rotates and drives gear 21 and gear 327 on the right side to rotate. Gear 327 rotates and drives gear 21 on the left side, so that both gears 21 can rotate inward or outward at the same time. Clamping block 13 is engaged with gear 21 and slides on slide rail 24. Therefore, gear 21 drives clamping block 13, so that clamping block 13 can clamp and open, thus clamping and fixing the mold, so that the mold will not be displaced under the action of punching force, and improving the positional accuracy of punching.

[0034] Reference Figure 1 , Figure 2 and Figure 5The damping mechanism 2 includes a limiting block 202, which is equidistantly installed on the upper left side of the support column 15. A hydraulic rod 201 is installed on the top of the limiting block 202, and a fixing block 203 is fixedly connected to the bottom end of the hydraulic rod 201. Multiple sliding rods 204 are equidistantly fixedly connected to the bottom of the fixing block 203, and the sliding rods 204 are slidably connected to the inner side of the limiting block 202. A connecting plate 205 is fixedly connected to the bottom end of the sliding rod 204, and multiple damping rods 207 are equidistantly installed on the bottom of the connecting plate 205. A spring 206 is installed on the outer wall of the damping rod 207, and a connecting plate 208 is installed on the bottom end of the damping rod 207. A spring 209 is installed on the outer wall of the connecting plate 205 and the connecting plate 208. When the hydraulic rod 201 is activated, the hydraulic rod 201 drives the fixing block 203 through transmission. When the fixed block 203 descends, it presses against the mold and comes into close contact with the mold through the connecting plate 208. During the stamping process, the punch 16 will cause the mold to vibrate, and the mold will transmit this vibration force to the spring 209 and the damping rod 207. The spring 209 is compressed under the action of vibration and absorbs part of the kinetic energy generated by the mold and the punch 16 through its elastic deformation, thereby reducing the transmission of vibration. This effect of reducing vibration transmission can significantly reduce the generation and propagation of noise. The right side of the outer wall of the operating table 5 is equipped with an electric wire 4, and the end of the electric wire 4 is equipped with a controller 3. Multiple threaded holes 22 are equally spaced on the top walls of the mounting block 14 and the mounting block 29. Bolts 23 are threaded on the inner side of the threaded holes 22, and the bolts 23 fix the mounting block 14 to the mounting block 29.

[0035] Specifically, the punch 16 reciprocates to punch holes in the mold on the processing plate 12. Then, the hydraulic rod 201 is activated, which drives the fixed block 203 to descend, causing the connecting plate 208 to press against the mold. The punch 16's punching causes the mold to vibrate, and the mold transmits the force to the spring 209 and the damping rod 207. The spring 209 is compressed, and through the elastic deformation of the spring 209, it absorbs part of the kinetic energy generated by the mold and the punch 16, reducing the transmission of vibration and thus reducing the generation and propagation of noise.

[0036] Reference Figure 2 , Figure 3 and Figure 5 A motor 17 is installed in the middle of the left side of the support column 15. A crank assembly 26 is installed at the output end of the motor 17. A punch 16 is installed at the end of the crank assembly 26.

[0037] Specifically, motor 17 drives crank assembly 26, which in turn powers punch 16, causing punch 16 to reciprocate and punch holes in the mold on processing plate 12.

[0038] Working principle: Motor 218 drives gear 20 to rotate. The rotation of gear 20 further drives the rotation of gear 21 and gear 327 on the right side, which are meshed with it. While rotating, gear 327 transmits power to gear 21 on the left side, thus achieving synchronous rotation of the two gears 21. This synchronous rotation mechanism allows the two gears 21 to rotate inward or outward as needed. Clamping block 13 is connected to gear 21 through meshing. Clamping block 13 can slide freely on slide rail 24. Therefore, when gear 21 rotates, it will drive clamping block 13, enabling clamping block 13 to perform clamping and opening actions. In this way, clamping block 13 can clamp the mold and hold it in place. In this way, the mold can remain stable under the action of punching force and will not be displaced, thus significantly improving the positional accuracy of punching.

[0039] Motor 17 drives crank assembly 26, which transmits power to punch 16, enabling it to reciprocate. This reciprocating motion is used to punch holes in the mold on processing plate 12. After punching, hydraulic rod 201 is activated, which drives fixed block 203 to descend via transmission. When fixed block 203 descends, it presses against the mold and makes close contact with it through connecting plate 208. During the punching process, punch 16 causes the mold to vibrate, and the mold transmits this vibration to spring 209 and damping rod 207. Spring 209 is compressed under the action of vibration and absorbs part of the kinetic energy generated by the mold and punch 16 through its elastic deformation, thereby reducing the transmission of vibration. This reduction in vibration transmission can significantly reduce the generation and propagation of noise, making the working environment quieter.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
