Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a shock-absorbing stamping die. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing separation or plastic deformation to obtain the desired parts. Buffer-type stamping dies often rust, affecting their surface quality and necessitating structural improvements. In commercially available stamping dies, lubricating oil penetration between dies is difficult, leading to jamming and rust on the product surface. This also reduces the production efficiency of buffer-type stamping dies, causing wear between parts. Furthermore, buffer-type stamping dies are prone to vibration and stamping deviations during operation, and surface dust cleaning is cumbersome, potentially causing internal mechanical failures. Utility Model Content

[0003] The purpose of this invention is to provide a shock-absorbing stamping die to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A shock-absorbing stamping die includes a stripper plate with mounting holes at each of its four corners. Guide sleeves are installed in the mounting holes, and a guide post passes through each guide sleeve. A rubber sleeve is fitted onto the top of each guide post. The rubber sleeve includes a first collar, a second collar, and a return spring. The first and second collars are spaced vertically on the guide post, and their inner diameters are both interference-fitted with the guide post. A plurality of first round rods are axially and evenly arranged on the top of the first collar, and a plurality of second round rods are axially and evenly arranged on the bottom of the second collar. The top of the return spring is fixedly connected to the second round rods, and the bottom of the return spring is fixedly connected to the first round rods. The guide post, guide sleeve, first collar, second collar, and return spring are all coaxially arranged.

[0005] By adopting the above technical solution, the rubber sleeve can absorb the kinetic energy on the guide post and reduce the resonance of the guide post. During use, the unloading plate needs to move up and down, and during the unloading process, the unloading plate will suddenly lose its blocking force, thereby impacting the guide post and causing the guide post to vibrate. Long-term internal micro-vibration will cause the fasteners of the entire upper mold structure to loosen. Therefore, it is necessary to absorb the kinetic energy of the vibration, extend the service life, and reduce the frequency of maintenance.

[0006] In a further embodiment, the outer diameter of the first collar is smaller than the outer diameter of the second collar.

[0007] By adopting the above technical solution, the energy is absorbed in stages through the first and second sets of rings, achieving a better recycling effect.

[0008] In a further embodiment, multiple return springs are provided, with one return spring provided between each of the first and second round rods.

[0009] In a further embodiment, rubber pads are provided at the four corners of the bottom of the unloading plate.

[0010] The above technical solution is used to absorb the impact kinetic energy of the unloading plate that suddenly loses its obstruction force.

[0011] In summary, this utility model has the following beneficial effects: 1. The rubber sleeve can absorb the kinetic energy on the guide pillar and reduce the resonance of the guide pillar. During use, the stripper plate needs to move up and down, and during the unloading process, the stripper plate will suddenly lose its blocking force, thereby impacting the guide pillar and causing it to vibrate. Long-term internal micro-vibration will cause the fasteners of the entire upper mold structure to loosen. Therefore, it is necessary to absorb the kinetic energy of the vibration, extend the service life, and reduce the frequency of maintenance. Attached Figure Description

[0015] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to the attached figures. Figure 1 In this specification, the terms "bottom surface" and "top surface," "inner" and "outer" refer to the direction toward or away from the geometry of a specific component. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this specification, "a plurality of" means two or more, unless otherwise explicitly and specifically defined by the direction of the center.

[0016] Example 1: like Figure 1 As shown, a shock-absorbing stamping die includes a stripper plate 1. Mounting holes are provided at each of the four corners of the stripper plate 1. Guide sleeves 2 are installed in the mounting holes, and guide posts 3 are inserted into each guide sleeve 2. A rubber sleeve 4 is fitted onto the top of each guide post 3. The rubber sleeve 4 includes a first collar 41, a second collar 42, and a return spring 43. The first collar 41 and the second collar 42 are spaced vertically onto the guide posts 3, and their inner diameters are both interference-fitted with the guide posts 3. Multiple first circles are evenly distributed axially on the top of the first collar 41. The bottom of the second ring 42 is axially and evenly provided with multiple second round rods. The top of the return spring 43 is fixedly connected to the second round rod, and the bottom of the return spring 43 is fixedly connected to the first round rod. The guide post 3, guide sleeve 2, first ring 41, second ring 42, and return spring 43 are all coaxially arranged. The outer diameter of the first ring 41 is smaller than the outer diameter of the second ring 42. Multiple return springs 43 are provided. There is a return spring 43 between each first round rod and second round rod. Rubber gaskets are provided at the four corners of the bottom of the unloading plate 1.

[0017] Specific implementation process: The rubber sleeve can absorb the kinetic energy on the guide pillar and reduce the resonance of the guide pillar. During use, the unloading plate needs to move up and down, and during the unloading process, the unloading plate will suddenly lose its blocking force, thereby impacting the guide pillar and causing it to vibrate. Long-term internal micro-vibration will cause the fasteners of the entire upper mold structure to loosen. Therefore, it is necessary to absorb the kinetic energy of the vibration, extend the service life, and reduce the frequency of maintenance. The first and second sets of rings are used to absorb the kinetic energy in stages to achieve a better recycling effect.
