Calibration device for processing thin-walled cylindrical parts

Abstract

The invention discloses a calibrating device for processing thin-walled cylindrical parts. A hinged pressing rod is arranged in a base body, a punching part for applying punching force is arranged on the pressing rod, and a punch and a first A positioning block is used as a die and a punch. When using, place the part to be processed on the first positioning block, and make its outer ring surface fit with the outer ring mating surface of the first positioning block, and then insert the punch through the flanging inner hole of the part and the first positioning block in turn Then hold the operating end of the pressing rod, so that the pressing rod hits the top surface of the punch through a rotary motion, and generates a component force along the flanging direction of the flanging convex cylinder, so that the forming part on the punch matches the forming hole. Pressure is applied to the inner and outer surfaces of the part, which in turn causes the part to plastically deform for flanging, so as to meet the processing needs.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a type calibration device used for processing thin-walled cylindrical parts. Background technique [0002] Flanging is a common form in the stamping process. Through the cooperation of punches and dies, the sheet metal parts to be processed are plastically deformed at specific positions, thereby being bent into various shapes. [0003] The flanging correction of the side wall holes of thin-walled cylindrical parts is for the long-term use or processing of the cylindrical parts, and the size of the flanged convex cylinder does not meet the requirements for use, so that it can be re-calibrated to make it meet the use again. need. However, for the flanging of the side wall holes of thin-walled cylindrical parts, the flanging direction is along the radial direction of the part cylinder, and the concave and convex die processing also needs to apply punching force to the...

AI Technical Summary

Problems solved by technology

However, for the flanging of the side wall hole of thin-walled cylindrical parts, the flanging direction is along the radial direction of the part cylinder, and the concave and convex die processing also needs to apply punching force to the radial direction of the part cylinder, but due to the rotation of the part itself characteristics, the cylinder wall will interfere with the configuration of the concave and convex molds, making it impossible to process

In this way, the conventional concave-convex die design cannot flang the side wall holes of cylindrical parts
