Punch with pressing device

Abstract

The invention discloses a punch with a pressing device, and belongs to the field of stamping die manufacturing. The fixed seat is mounted on an upper die or a wedge of the stamping die and is locked by a bolt and positioned by a pin, and the concave die is fixed on a lower die of the stamping die; the small-diameter shaft at one end of the guide column penetrates into the fixing seat, the fixing seat and the small-diameter shaft at one end of the guide column are locked together through a bolt, the spring is sleeved on the large-diameter shaft in the middle of the guide column and is limited through the spring chuck, and the spring chuck is sleeved on the small-diameter shaft at the other end of the guide column and is positioned through a shaft shoulder of the guide column. The punch and a small-diameter shaft at the other end of the guide column are locked together through a bolt, the punch is tightly attached to the spring chuck, the pressing head is installed on a guide face, used for guiding and positioning the pressing head, on the side face of the punch, the vertical stroke stop point of the pressing head is limited through a limiting bolt installed on the side face of the punch, and the jigger pin is installed on the punch. The die is simple in structure, high in general interchangeability, small in occupied space and stable in punching force, an independent material pressing core can be omitted, and the die manufacturing cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of cold stamping die manufacturing, in particular to a punch with a self-contained material pressing device. Background technique [0002] The punching process often requires pressing before punching, and the conventional practice is to design a separate pressing core. The traditional press core needs to use nitrogen cylinder as pressure source and guide plate or guide post as guide device. These devices usually require a lot of installation space. The punching is completed in multiple processes, so that new molds need to be added to complete the punching, resulting in an increase in the cost of workpiece tooling and subsequent production costs. SUMMARY OF THE INVENTION [0003] In order to overcome the shortcomings that the traditional pressing material occupies a large space and the pressing material cannot be arranged in a small space, the purpose of the invention of the present invention is to provide...
