Copper pipe shrinking equipment

Abstract

The invention relates to a necking device for copper pipes. The necking device comprises a machine table, and a feeding mechanism, a pushing mechanism and a necking mechanism arranged on the machine table, wherein the feeding mechanism is used for sorting the copper pipes and then conveying the copper pipes to the pushing mechanism one by one; the pushing mechanism is arranged on one side of the feeding mechanism and is used for pushing the copper pipes, which are conveyed to the pushing mechanism through the feeding mechanism, to the necking mechanism; the necking mechanism comprises a copper pipe fixing device and a necking rotary disc which are arranged on the machine table; the copper pipe fixing device is arranged close to the pushing mechanism and is used for fixing the copper pipes pushed by the pushing mechanism; the necking rotary disc is arranged on the machine table through a movable supporting base; the necking rotary disc is rotationally matched with the supporting base; the necking rotary disc comprises a disc-type base, a plurality of necking pipes arranged on the outer circumference of the base and a rotatable rotating knife assembly; and a necking mould penetrating through the outer end of a necking head part is arranged at the head part of the necking pipe.

Description

Technical field [0001] The invention relates to the field of copper pipe machining, in particular to a necking device for copper pipes. Background technique [0002] In the existing industrial products and daily-use products, it is often encountered that pipes of different pipe diameters are connected. Generally, joint connection is used, and joint connection will cause leakage problems. In many cases, leakage is not allowed. It is only possible to add a tapered tube in the middle of the tubes of different diameters, and then weld the tubes of different diameters into one body by welding at both ends. [0003] In order to meet the process requirements, it is often necessary to shrink the copper tube during the deep processing of the copper tube to make the copper tube reach an outer diameter that meets the process requirements. [0004] The shrinking machine in the prior art is usually a processing machine that shrinks the end face of a pipe fitting. In the prior art, the copper pip...

Problems solved by technology

[0004] The necking machine in the prior art is usually a processing machine for shrinking the end face of the pipe fittings. In the prior art, the copper pipe necking is mostly performed by knocking type necking equipment, stamping type necking equipment or clamping on a drilling machine or a lathe. Rotary compression mouth, the above necking process often has the defects of low degree of automation and unsatisfactory necking quality
