Secondary precision extrusion forming process system and method for electric vehicle head pipe

Abstract

The invention discloses a secondary precision extrusion forming process system and method for an electric vehicle head pipe. The secondary precision extrusion forming process system comprises a base,a clamping table and a punch forming device, wherein the clamping table is arranged on the base in a sliding mode and driven by a first air cylinder to move; a clamping pipe for accommodating a head pipe is arranged on the upper surface of the clamping table, an ejector rod is arranged in the clamping pipe, and the ejector rod is in transmission connection with a second air cylinder below the clamping table; the punch forming device comprises a main plate, a sliding plate and two punching drill bits; the main plate is horizontally arranged above the clamping table in a spanning mode and is driven by a hydraulic cylinder to vertically move; the sliding plate is arranged below the main plate and driven by a third air cylinder to slide, and the sliding direction is consistent with the slidingdirection of the clamping table; the two punching drill bits are vertically fixed below the sliding plate and arranged in the sliding direction of the clamping table. The head pipe can be rapidly assembled and disassembled, and the safety performance is good.

Description

technical field [0001] The invention relates to the technical field of electric head tube processing, in particular to a secondary precision extrusion forming process system and a forming process method for an electric head tube. Background technique [0002] The head pipe is one of the important parts in the electric vehicle frame, and the upper and lower ends of the head pipe are respectively connected to the steering handle and the front fork of the electric vehicle. In the forming process of the head tube, it is necessary to press and form the end of the head tube so that the end of the head tube can be formed into a desired shape so as to be connected with the steering handle or the front fork. The end of the head tube of some electric vehicles cannot be formed by a single stamping process, and needs to be transformed into the required shape after two stampings. Therefore, it is necessary to provide a continuous forming device for the end of the head tube with good safe...

AI Technical Summary

Problems solved by technology

The end of the head tube of some electric vehicles cannot be formed by a single stamping process, and needs to be transformed into the required shape after two stampings. Therefore, it is necessary to provide a continuous forming device for the end of the head tube with good safety performance and high production efficiency.
