Description

Technical Field

[0001] This utility model relates to the field of pneumatic punching machine technology, and in particular to a pneumatic punching machine for processing rubber parts. Background Technology

[0002] The processing of rubber parts involves multiple stages, among which punching is one of the key steps. The punching process aims to precisely cut rubber materials into predetermined shapes and sizes to meet the specifications of different products. This process requires the use of specialized punching equipment. By applying sufficient pressure, the mold and the rubber material can fully interact to achieve precise molding. Therefore, it is necessary to design a pneumatic punching machine for processing rubber parts.

[0003] In traditional pneumatic press operations for rubber parts processing, the feeding and unloading processes largely rely on manual operation. This is not only inefficient but also easily affected by factors such as worker skill level and fatigue, leading to inaccurate feeding and unloading positions. Consequently, this affects stamping accuracy and product quality. Installing an automatic feeding and unloading structure can complete the corresponding actions quickly and accurately, significantly shortening the production cycle of a single product and increasing output per unit time. During press operation, high-frequency or high-pressure stamping can cause the die to shift or shake due to vibration and impact, resulting in stamping position deviations. This makes it difficult to guarantee the dimensional accuracy of rubber parts, increasing the defect rate. Installing a specialized rubber die clamping structure can effectively solve the problems of unstable die fixation and inaccurate positioning, improving the stamping accuracy of rubber parts, reducing the defect rate, and enhancing product quality. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The purpose of this utility model is to provide a pneumatic punch for processing rubber parts, which solves the problems mentioned in the background art, such as reliance on manual operation, low efficiency, and susceptibility to factors such as worker skill level and fatigue, which affect stamping accuracy and product quality, and unstable mold fixing and inaccurate positioning, making it difficult to guarantee the dimensional accuracy of rubber parts and increasing the defect rate.

[0008] As a further embodiment of this utility model, limit holes are provided on both the left and right sides of the stamping table, and limit rods pass through the inside of the limit holes. The setting of the limit rods plays a role in preventing the stamping table from deviating during stamping.

[0009] As a further embodiment of this utility model, a base plate is fixedly connected to the bottom of the stamping table, and columns are fixedly connected to both the left and right sides of the base plate. The columns provide support.

[0010] As a further embodiment of this utility model, a pneumatic platform is slidably connected to the outside of the column, and a stamping block is fixedly connected to the bottom of the pneumatic platform. The stamping block facilitates stamping into a specified size and shape.

[0011] As a further embodiment of this utility model, the bottom of the air jet machine is equipped with a base, and the bottom of the base is fixedly connected with a support leg, which provides support at the bottom.

[0012] As a further embodiment of this utility model, a control console is fixedly connected to the upper right side of the base, and control buttons are installed on the surface of the control console. The control console enables manual control of the device's operation.

[0013] As a further embodiment of this utility model, a clamping pad is installed on the inner side of the clamping plate. The clamping pad is made of soft rubber. The clamping pad helps to prevent the external mold from loosening.

[0014] (III) Beneficial Effects

[0015] This utility model provides a pneumatic punch for processing rubber parts, which has the following advantages:

[0016] 1. The pneumatic punching machine for processing rubber parts, through the setting of the feeding mechanism, when the device is to be used, the drive motor is turned on, driving the slider inside the bottom rod to move back and forth outside the lead screw and limit rod. Since a punching table is installed on the top of the slider, the punching table can move back and forth with the slider, which facilitates the automatic feeding and picking of materials by the punching table. This avoids relying on manual operation, which is not only inefficient, but also easily affected by factors such as the worker's skill level and fatigue, resulting in inaccurate feeding and picking positions, thus affecting the stamping accuracy and product quality.

[0017] This pneumatic punch for processing rubber parts, through the setting of the clamping mechanism, first places the external rubber mold on the punching table when the device is to be used. Then, according to the size of the external mold, the telescopic hydraulic rod on the inner side of the top of the support rod is adjusted so that the clamping plate at the top can clamp the two sides of the external mold, fixing the external mold. Since a clamping pad is also installed inside the clamping plate, it can prevent the mold from sliding and reduce the clamping force while clamping. It plays a role in facilitating clamping and fixing, preventing displacement and movement, and avoiding the mold from being easily displaced or shaken by factors such as vibration and impact, which would lead to stamping position deviation, making it difficult to guarantee the dimensional accuracy of the rubber parts and increasing the defect rate.
