Abstract

A punching assembly includes a die base, a sleeve, an adjusting screw, a pull portion, a latching block, an elastic element, a fixing ring and a stop member. A top of the die base is received in the sleeve. The adjusting screw includes a contact end, a mounted end inserting into the sleeve and connecting to the top of the die base, and a latching portion located between the contact end and the mounted end. The pull portion is disposed around the sleeve. The latching block engages the latching portion. The elastic element is disposed around the adjusting screw, supporting the latching block. The fixing ring surrounding the adjusting screw is fixed on the sleeve. The stop member, contiguous with the fixing ring, prevents axial movement of the adjusting screw.

Dependent claims

A punching assembly, comprising:

a die base, comprising at least one pin thereon;
and
a base adjusting device for adjusting a base level of the die base, comprising:
a sleeve comprising a first end defining at least one first guiding hole, a second end defining at least one second guiding hole and a stage on an inner wall thereof, the die base partially received in the sleeve, the pin and the at least one second guiding hole cooperatively guiding the die base movable along the second guiding hole;
an adjusting screw comprising a contact end and a mounted end received in the sleeve from the first end and connected to the die base via screws, and a latching portion configured between the contact end and the mounted end;
a latching block disposed around the adjusting screw and adapted for engaging with the latching portion;
