Correcting device for machining thin-wall cylinder parts

Abstract

The invention discloses a correcting device for machining thin-wall cylinder parts. The correcting device is characterized in that a hinged pressing rod is arranged in a base body, a punching part forapplying punching pressure is arranged on the pressing rod, and a punch and a first positioning block are arranged to be used as a female die and a male die respectively. When in use, the parts to bemachined are placed on the first positioning block, the outer ring surfaces of the parts to be machined are attached to the outer ring matching surface of the first positioning block, then the punchis sequentially inserted into flanging inner holes of the parts and a forming hole of the first positioning block, and then the operating end of the pressing rod is held with hands, so that the pressing rod hits the top surface of the punch through rotary motion, component force in the flanging direction of flanging convex cylinders is generated, consequently, the forming part on the punch is matched with the forming hole to exert pressure on the inner surfaces and the outer surfaces of the parts, then the parts are subjected to plastic deformation for flanging, and thus the machining requirement is met.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a calibration device for processing thin-walled cylindrical parts. Background technique [0002] Flanging is a common form in the stamping process. Through the mutual cooperation of the punch and die, the sheet metal parts to be processed are plastically deformed at specific positions, and thus are bent into various shapes. [0003] The flanging calibration of the side wall holes of thin-walled cylindrical parts is to recalibrate the size of the flanging convex cylinder if the cylindrical parts do not meet the use requirements during long-term use or processing, so that they can meet the use requirements again. need. 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 dire...

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
