Description

Technical Field

[0001] The utility model belongs to the technical field of punching machines for multi-station machines, and particularly relates to a punching needle structure for a multi-station machine punching machine. Background Art

[0002] For an ordinary punching needle of a multi-station machine, the head is flat, as Figure 1 shown, and it is a solid head. After the mold is made, burrs will appear during the mold trial process, and it is not durable, resulting in unqualified molds. When punching a sheet material, it is easy to punch through the sheet material, causing the overall scrapping of the sheet material mold, wasting processing materials and increasing production costs. Summary of the Utility Model

[0003] An object of an embodiment of the utility model is to provide a punching needle structure for a multi-station machine, which can avoid burrs on the sheet material during punching and improve the durability.

[0004] The embodiment of the utility model is implemented as follows:

[0005] A punching needle structure for a multi-station machine for punching a sheet material, comprising:

[0006] A needle base, a needle body and a needle end. One end of the needle body is fixed to the needle base. The needle body and the needle base are integrally formed, and both the needle body and the needle base are cylindrical. The end face diameter of the needle base is larger than the end face diameter of the needle body. The other end of the needle body is the needle end. The periphery of the needle end is higher than the center of the needle end, forming an arc shape with a concave middle and a convex circumference. The radius length of the arc is the diameter length of the needle body.

[0007] Multiple punching needles of the punching needle structure are arranged on the multi-station machine, and are arranged in parallel at intervals.

[0008] The needle end is hollow.

[0009] Through the designed punching needle of the multi-station machine in the embodiment of the utility model, these adverse phenomena occurring during the mold trial process are effectively solved. Burrs will not appear, the punching needle is sharp and durable, and the customer satisfaction is improved. Since in the punching needle structure of the utility model, the head of the punching needle is an arc structure, the head remains sharp, is easy to punch holes and does not form burrs. The radius length of the arc is the diameter length of the needle body, making the arc surface of the punching needle head smoother, ensuring sharpness and durability at the same time. On the other hand, when the arc structure is punching, the sheet material in contact with the arc part is forced to bend to form a buffering effect, so the sheet material is not easily damaged, the yield rate of sheet material punching is improved, and the production cost is reduced. In addition, when the needle end is hollow, during punching, the buffering of the sheet material is greater, further reducing the damage to the sheet material during punching and further improving the punching quality. Brief Description of the Drawings

[0010] Figure 1It is the structural diagram of the punching punch of a multi-station machine in the prior art;

[0011] Figure 2 It is the overall structural diagram of the punching punch of the multi-station machine of the present invention;

[0012] Figure 3 It is the end face structural diagram of the punching punch of the multi-station machine of the present invention. Specific embodiments

[0013] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0014] The following describes the specific implementation of the present invention in detail with specific embodiments:

[0015] As Figure 2 and Figure 3 shown, a punching punch structure of a multi-station machine for punching a sheet material includes:

[0016] A needle base 1, a needle body 2 and a needle tip 3. One end of the needle body is fixed to the needle base. The needle body and the needle base are integrally formed, and both the needle body and the needle base are cylindrical. The end face diameter of the needle base is larger than the end face diameter of the needle body. The other end of the needle body is the needle tip. The peripheral edge of the needle tip is higher than the center of the needle tip, forming an arc with a concave middle and a convex circumference. The radius length of the arc is the diameter length of the needle body.

[0017] Multiple punching punches are arranged on the multi-station machine, and are arranged in parallel at intervals.

[0018] The needle tip is hollow.

[0019] In the embodiment of the present invention, through the designed punching punch of the multi-station machine, these bad phenomena occurring in the trial die process are effectively solved. There will be no burrs, the punching punch is sharp and durable, and the customer satisfaction is improved. Since in the punching punch structure of the present invention, the head of the punching punch is an arc structure, the head remains sharp, is easy to punch holes and does not form burrs. The radius length of the arc is the diameter length of the needle body, making the arc surface of the head of the punching punch smoother, ensuring sharpness and durability at the same time. On the other hand, when the arc structure is punching, the sheet material contacted by the arc part is forced to bend to form a buffering effect, so the sheet material is not easily damaged, the qualified rate of sheet material punching is improved, and the production cost is reduced. In addition, when the needle tip is hollow, during punching, the buffering of the sheet material is greater, further reducing the damage to the sheet material during punching and further improving the quality of punching.

[0020] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
