Abstract
The present invention discloses a stainless-steel tee-pipe moulding process, cutting out a main pipe and a secondary pipe from the stainless-steel pipe to replace the copper tee-pipe to resolve the problem that the copper tee-pipe is easy to corrode and causes water pollution; meanwhile, the moulding process of the stainless-steel tee-pipe of the invention is different from the traditional integral forming process, and saves more materials and reduces the production cost compared with the traditional integral forming process.
Claims7
A stainless-steel tee-pipe moulding process, wherein it comprises the following steps:
- S1, by taking a stainless-steel pipe as a processing raw material, cutting out a main pipe and a secondary pipe from the stainless-steel pipe;
- S2, flaring the bodies of the main and secondary pipes with a flaring apparatus;
- or necking two ports of the main pipe and one port of the secondary pipe with a necking apparatus;
- S3, carrying out thread treatment on the two ports of the main pipe and one port of the secondary pipe with a thread forming apparatus to form connecting threads;
- S4, forming a T-branch port on the body of the main pipe obtained after treatment in S3, meanwhile, cutting the other port of the secondary pipe to obtain a docking port matched with the T-branch port, and then welding the docking port of the secondary pipe with the T-branch port of the body of the main pipe to form a tee-pipe blank;
- and
- S5, carrying out surface electroplating on the tee-pipe blank obtained after treatment in S4 to form a tee-pipe end product.
