Problems solved by technology

At present, the existing technology uses high-frequency welding to process copper-aluminum composite structure products similar to the tank type container, but the weld formed by high-frequency heating is composed of brittle welds, which are brittle and cannot resist high-pressure damage. Structurally vulnerable under pressure, not used in practice

Embodiment Construction

[0040] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0041] This embodiment is a production implementation case of a copper-aluminum composite structure resistant muffler. The resistant muffler is composed of an aluminum tube 6 as a muffler shell, a copper muffler pipe 7 and an outlet copper joint 1. It is used as a muffler. The aluminum tube 6 of the device shell is a drum-shaped aluminum tube that shrinks at both ends and bulges in the middle after being squeezed inside; the copper silencer tube 7 is a concentric copper tube with the same inner diameter; one end of the outlet copper joint 1 and copper One end of the muffler tube 7 is respectively inserted into the two shrink ends 8 and 9 of the aluminum tube 6 as the muffler shell; the contact section 10 between the copper and aluminum tubes is welded by pressing and inserting while being energized and heated to form a copper and aluminum tube ...

Abstract

The invention relates to a manufacture method for copper-aluminum composite structure metal cans, belonging to metal composite structure processing technology field, which comprises an aluminum tube, an inlet copper tube and an outlet copper tube joining together. The invention adopts the steps that: firstly, the middle part of the aluminum tube is squeezed by hydraulic pressure to an enlarged drum aluminum tube, which has invariant diameter on both ends and a raised middle part; secondly, one port of the inlet copper tube and the outlet copper tube is mechanically processed into a conical surface; finally, the conical surface port of the inlet copper tube and the outlet copper tube is inserted into the taper end of the drum aluminum tube. As the conical surface port is pressured into the taper end while being electrically heated, a fixed metallic bond joint of copper-aluminum tube is formed at the contacting segment.

Description

technical field [0001] The invention relates to a method for manufacturing a copper-aluminum composite structure metal tank body. Specifically, it processes an aluminum tube or an aluminum alloy tube into a tank structure with thin ends and a raised middle through extrusion. The copper tube is processed into a structure that is easy to be welded to form a firm metal bond connection, and then the thin openings at both ends of the copper tube and the aluminum tube are welded together. The production method of the copper-aluminum composite structure metal tank body. The device made by the invention can be easily connected with other copper pipelines, thereby reducing product cost. The invention is suitable for making tank shells such as accumulators, filters, filters, temporary storage tanks, energy storage tanks, liquid storage devices, mufflers, etc., and belongs to the technical field of metal composite structure processing. Background technique [0002] Usually, when desig...
