[0002] A punch press is a stamping press. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that cannot be achieved by mechanical processing through various mold applications. Therefore, its use is becoming more and more extensive.

[0003] The prior art discloses a punching machine with a protective function with an application number of 202121271739.8, including a punching machine body and a shock absorbing mechanism, wherein the punching machine body includes a base, a workbench and an upper body, and the workbench is fixedly installed above the base. The utility model relates to a technical field. By setting an adjustment rod, the staff can adjust the spacing between the two splash guards according to the size of the processed steel plate during operation, thereby ensuring the stability of the clamping. The top plate is used to prevent the bending of both sides of the steel plate during the punching process, prevent the steel plate from deforming, and thus ensure the quality of the punching. The splash guard enables the punch to effectively protect the workpiece placed on the die base during operation, and prevent the processed material from splashing out during the pressing process, thereby improving the safety of using the punching machine, protecting the operator, and enabling the operator to be more assured when operating the punching machine, thereby improving the processing efficiency of the punching machine. However, the existing technology still has the problem of inconvenience in taking the workpiece after stamping. Generally, it is very troublesome to manually reach into the stamping groove to take the workpiece, and it is necessary to use tools to clamp the workpiece and take it out. This is not only troublesome to take out the mold, but also easy to cause safety hazards. For this reason, we propose a new type of punching device for punching machines to solve the above problems. Utility Model Content

[0004] In view of the shortcomings existing in the above problems, the utility model provides a novel punching device for a punching machine, which can eject the workpiece from the punching groove by adjusting the ejector plate to move upward after the punching process is completed, so as to facilitate the demoulding of the workpiece and facilitate manual picking.

[0005] In order to solve the above problems, the technical solution provided by the utility model is as follows:

[0007] Furthermore, the protective assembly includes a protective pull plate and a protective transparent plate, the protective transparent plate is slidably inserted into the interior of the top plate, the upper end of the protective transparent plate is fixedly connected to the protective pull plate, and there is an interference fit between the protective transparent plate and the top plate.

[0008] Furthermore, the protective transparent plate is a tempered glass plate.

[0009] Furthermore, the number of the push rods is four, and the four push rods are distributed at four corners of the upper end surface of the push plate.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. During the stamping operation, the stamping cylinder pushes the punch installed under the mounting plate downward, so that the punch punches the workpiece placed in the stamping groove;

[0012] 2. A protective component is provided on the top plate to play a certain safety protection role, preventing waste from splashing during the stamping operation, and improving the safety of using the punch press. During the stamping operation, the protective transparent plate is pulled so that the protective transparent plate is located in front of the operator, so that the protective transparent plate can prevent waste from splashing onto the operator's body and avoid causing harm to the operator;

[0013] 3. After the workpiece is stamped, the motor is turned to drive the screw to rotate. When the screw rotates clockwise, the screw drives the push plate to rise, and then drives the ejector plate to rise. The ejector plate ejects the workpiece from the stamping slot, and the operator does not need to reach into the stamping slot to take out the workpiece, which is convenient for taking out the workpiece. At the same time, it also avoids the safety risks of the operator reaching into the stamping slot to take out the workpiece.

[0014] In summary, this new type of punching device for punching machines has wide practicality, and can solve the problem that the prior art proposed in the above background technology still has the problem of inconvenience in taking the workpiece after stamping. Generally, it is very troublesome to manually reach into the stamping groove to take the workpiece, and it is necessary to use tools to clamp the workpiece and take it out. This mold removal is not only troublesome, but also easily causes safety hazards. It has wide promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
