Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] refer to figure 1 , a preparation process of bimetallic thin-wall composite pipe, comprising the following steps:

[0023] 1), billet treatment, the surface of the billet 3 bar and the metal pipe 8 is treated respectively to make the surface free of oxide layer, clean and pollution-free,

[0024] 2), the continuous extrusion blank 3 and the metal pipe 8 are compounded, referring to figure 2 , the continuous extrusion machine is composed of an extrusion roller 1, a compacting wheel 4, an extrusion shoe 6, a plug 10, a punch 7 and a die 11, and two extrusion rollers 1 of the continuous extrusion machine are symmetrically distributed, The two extrusion rollers 1 are controlled by servo motors. There is a groove 2 on the extrusion roller 1. The billet 3 is pressed into the groove 2 on the extrusion roller 1 by the compaction wheel 4. With the rotation of the ex...

Abstract

The invention relates to a process for manufacturing a bimetal thin-wall composite pipe, which comprises the following steps of: processing a blank; continuously extruding the blank to compound the blank with a metal pipe, and feeding the processed blank bar and the metal pipe into a continuous extruder for compounding, wherein the continuous extruder is provided with two extrusion rollers which are symmetrically arranged and are controlled by a servo motor; keeping the metal pipe not deformed in the extrusion process, pressing the blank in grooves on the extrusion rollers, making the blank enter an extrusion cavity under the drive of friction force, raising the temperature of the blank under the double action of the friction force and extrusion deformation, and making the blank subjected to plastic deformation, extruded to a cavity and coated on the surface of the metal pipe along two symmetrical surfaces; drawing, namely feeding the bimetal composite pipe formed by continuous extrusion into drawing equipment, and designing the deformation size of a coating layer and the metal pipe in the drawing process to make the coating layer and the metal pipe synchronously deformed and have the same deformation; and sawing and finishing. The prepared bimetal thin-wall composite pipe does not have any weld seam, and is short in process flow and high in production efficiency.

Description

technical field [0001] The invention belongs to the technical field of metal plastic forming, and in particular relates to a preparation process of a bimetallic thin-walled composite pipe. Background technique [0002] Automobile radiators are necessary auxiliary heat exchange equipment for automobile air conditioners and engines. In the field of automobile lightweight research, the lightweight of automobile radiators is a major research field. Due to its high heat dissipation efficiency, the aluminum alloy advective condenser is widely used in automobile engine radiators and automobile air conditioners, and is gradually developing into the field of household air conditioners. The aluminum alloy composite tube coated with brazing material is the key equipment required for the manufacture of flat-flow condensers. [0003] At present, the production process of aluminum alloy composite pipes for air conditioners is to firstly roll brazing materials and aluminum plates to obtai...
