Problems solved by technology

[0002] At present, the quick-connect pipes used for water heaters and plumbing fittings generally consist of two parts, the installation part and the pipe part. The sealing groove; its production process is to process the pipeline part and the installation part separately, and then weld them to form a finished product. The steps are cumbersome, which increases the production cost; second, the finished products formed by welding are prone to defective products. After a long period of use, the welding points are easy to be damaged and the service life is short

Embodiment Construction

[0025] The present invention will be further described below with specific embodiment, see Figure 1-8 :

[0026] A production process for quick-connect pipes, comprising the following steps:

[0027] 1) One-time flaring: one end of the round pipe is flaring, and the round pipe becomes a large-diameter round pipe 2 at one end and a small-diameter round pipe 1 at the other end;

[0028] 2) One-time shaping: the round tube made in step 1) is shaped, and two sections of round tubes with different diameters are adjusted in place according to the length requirements;

[0029] 3) Tube shrinking: shrink the right side of the large-diameter circular tube 2a made in step 2) according to the diameter of the small-diameter circular tube 1a to form a tube-shrinking section 2b, and the left side of the large-diameter circular tube 2a has an outward protrusion The large convex ring 3;

[0030] 4) secondary shaping: carry out secondary shaping to the circular tube made in step 3), and adj...

Abstract

The invention discloses a production technology for a quick coupling tube, and belongs to the technical field of coupling tubes. The production technology comprises the following steps of: 1) primary flaring; 2) primary shaping; 3) pipe contraction; 4) secondary shaping; 5) secondary flaring; 6) forming convex rings. The product produced by the production technology has an integral structure, and has the advantages of even tube wall, high firmness, attractive appearance, low cost, convenient and reliable use and long service life; therefore, the production technology for the quick coupling tube is applicable to quick coupling tubes of water heaters and plumbing pipe fittings.

Description

Technical field: [0001] The invention belongs to the technical field of connecting pipes, in particular to a production process of quick connecting pipes. Background technique: [0002] At present, the quick-connect pipes used for water heaters and plumbing fittings generally consist of two parts, the installation part and the pipe part. The sealing groove; its production process is to process the pipeline part and the installation part separately, and then weld them to form a finished product. The steps are cumbersome, which increases the production cost; the second is that the finished product formed by welding is prone to defective products. After the product is used for a long time, the welding point is easy to be damaged and the service life is short. Invention content: [0003] The object of the present invention is to provide a production process of quick-connect pipes with low cost, convenient use, reliability and long service life. [0004] The present invention...
