Description

Technical Field

[0001] The utility model relates to the technical field of tapping inside a stamping die, in particular to a tap chuck assembly with a fast-forward function. Background Art

[0002] In the prior art, there is often a problem: due to the requirements of the stamping forming process, there will be a process surface with a height difference before and after the tooth hole, and the difference is greater than 5mm. In order to avoid the raised part, the tap needs to be quickly raised after the in-mold tapping machine completes the tapping, so as to avoid these raised parts in the shortest time and facilitate the forward feeding of the workpiece material strip. The current method to achieve rapid up and down movement is to use a cylinder or elastic mechanism to make the in-mold tapping machine move up and down as a whole to achieve rapid lifting and lowering of the tap.

[0003] However, during the above movement, there are the following problems: the whole or part of the lifting is complicated in structure, and a larger mold space is occupied. If it is a large stamping part, the corresponding in-mold tapping machine is larger, and the up and down movement easily makes the in-mold tapping machine unstable, reducing the service life of the whole machine. In view of this, a tap chuck assembly with a fast forward function is provided to overcome the above defects. Utility Model Content
