Extrusion equipment and production process of conductive stainless steel plate lateral feeding type composite conductive track

Abstract

The invention discloses extrusion equipment and a production process of a conductive stainless steel plate lateral feeding type composite conductive track. The extrusion equipment comprises a forming mold plate, a through mold and a feeding plate mold. A method comprises the following steps: fixing the forming mold plate, the through mold and the feeding plate mold; producing a wear-resistant conductive stainless steel plate according to the regulations, and inserting the wear-resistant conductive stainless steel plate into a feeding channel of the through mold; heating and softening a conductive track base material, sequentially extruding the heated and softened conductive track base material into a base material feeding opening, a base material feeding channel and a conductive track cavity through an oil cylinder, physically combining the conductive track base material and the wear-resistant conductive stainless steel plate at set temperature and under set pressure, and extruding from the conductive track cavity; performing conventional thermal treatment and surface treatment on a crude composite conductive track product to obtain a finished composite conductive track product. The extrusion equipment is simple in structure; the tensile strength and the mechanical strength of the product produced by adopting the method are greatly improved, and the resistance of the conductive track is reduced.

Description

technical field [0001] The invention discloses an extrusion equipment for a conductive stainless steel plate side-feed type composite conductive track. The invention also discloses an extrusion production method for a conductive stainless steel plate side-feed type composite conductive track. The invention belongs to the mobile Technical field of production of power supply devices. Background technique [0002] The trolley line is a mobile power supply device, and its function is to contact the brush to supply power to the brush. It is mainly used for lifting in workshops, assembly line production, and mobile power supply for various bridge cranes, door cranes and trams at stations and docks. When the current trolley line composite conductive track is produced, the aluminum rail and the stainless steel strip are pre-formed, and then the aluminum rail and the stainless steel strip are rolled and formed at room temperature. This method makes the manufactured trolley line comp...

AI Technical Summary

Problems solved by technology

When the current trolley line composite conductive track is produced, the aluminum rail and the stainless steel strip are pre-formed, and then the aluminum rail and the stainless steel strip are rolled and formed at room temperature. This method makes the manufactured trolley line composite conductive track have a contact surface Disadvantages such as not tight enough and poor conductivity

[0003] Later, it applied for "a single-cylinder extrusion equipment and production method for trolley line composite conductive track" and "a double-cylinder extrusion equipment and production method for trolley line composite conductive track", and their application numbers are 201310120449.7 respectively and 201310118178.1, when these two schemes are actually implemented, the existing equipment must be greatly modified, which undoubtedly increases the production cost of the enterprise, and the structure of the modified extrusion equipment is also relatively complicated
