Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a punching machine ejection and discharging mechanism. Background Art

[0002] A stamping machine is a device used to implement stamping processing. It applies external force to materials such as plates, strips, and pipes through a press and a die to cause plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. The ejector mechanism of the stamping machine is an important part of the stamping process. It is responsible for pushing the processed parts out of the die. The ejector mechanism plays a vital role in the stamping machine. It ensures that the processed parts can be discharged from the die smoothly and efficiently, thereby ensuring the continuity and automation level of the entire production process.

[0003] In the prior art, the ejection mechanism of a punching machine disclosed in the patent publication number CN214349195U mainly realizes the manual ejection of the material from the mold cavity by setting an elastic support rod.

[0004] It is known from the technology in related fields that for the ejection mechanism of the stamping machine, most of the mechanisms have poor cleaning effect on the mold cavity when ejecting the material after stamping. During stamping, it is inevitable that metal debris will adhere to the inner wall of the mold cavity, thereby affecting the subsequent stamping effect. The self-cleaning ability is poor, and the effect is poor when used continuously. Utility Model Content

[0011] Blowing unit: It is arranged on the belt coil. While ejecting the workpiece to clean the inner wall of the mold cavity, it can further blow air to the inner wall of the mold cavity to improve the cleaning effect of the inner wall of the mold cavity.

Since the distal end of the rotating drum rod 14 is always located in the spiral guide rod groove 13, the column 11 can rotate while moving upward, and then rotate with its circumferential cleaning brush 12. While ejecting the workpiece, the inner wall of the mold cavity 5 is thoroughly cleaned to prevent the adhesion of metal debris, etc., with stronger self-cleaning ability, better effect of continuous use, and higher work efficiency.

[0028] Blowing unit: It is installed on the coil 8.
