Scrap-edge-free automatic stamping die for producing long-tail ticket holder

Abstract

The invention discloses a waste-edge-free automatic stamping die for producing a long-tail ticket holder. The waste-edge-free automatic stamping die comprises an upper die, a lower die, an ejection fixing device, a trimming device and a discharging device, a mounting groove is formed in the upper die, the mounting groove is shaped like a Chinese character 'tu ', a die cavity and a mounting cavity are formed in the lower die, the mounting cavity is located below the die cavity and communicates with the die cavity, and the upper die is slidably inserted into the die cavity. The ejection fixing device is used for ejecting and fixing a long strip, the ejection fixing device is movably mounted in the mounting groove, the trimming device is used for rotatably polishing peripheral burrs on the long strip, the trimming device is movably mounted in the mounting cavity, and the discharging device is used for discharging the trimmed long strip. The discharging device is movably mounted in the trimming device. The invention discloses the waste-edge-free automatic stamping die for producing a long-tail ticket holder, and can solve the problems that waste edges generated when the long strip is formed through stamping in the prior art need to be removed for the second time, and time and labor are wasted.

Description

technical field [0001] The invention relates to the technical field of long-tail ticket holder production, in particular to an automatic stamping die without waste edge for the production of long-tail ticket holders. Background technique [0002] In the production of long-tailed bill clips, it is necessary to stamp the plate to form a long strip, and then bend and curl the long strip to form a steel clip. Since the plate has a certain thickness during stamping, the mold will tear the plate when it is matched with stamping, which is easy Waste edge, also called burr, refers to the part of the edge of the metal workpiece that is not smooth and uneven. [0003] At present, burrs are generated around the long strips. The burrs cause unevenness around the product, which seriously affects product quality. It is necessary to remove the burrs from the long strips a second time, which is time-consuming and laborious, and increases production costs. Contents of the invention [000...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention discloses an automatic stamping die without waste edges for the production of long-tailed ticket holders, which can solve the problem that the waste edges generated when stamping into long strips need to be removed twice, which takes time and effort.
