Embodiment 1

[0019] Select qualified copper pipe blanks after series stretching, put the copper pipe blanks into the coil drawing machine, inject lubricating oil into the inner wall of the copper tube, so that the inner wall of the copper tube is covered with lubricating oil; start the machine to pull Stretching; After the stretching is completed, the copper tube is finished and wound, and then directly annealed and packaged to obtain a smooth copper tube. The lubricant used in the above steps is composed of: 60-80% of naphthenic base oil, 10-30% of polyalphaolefin, and 10-20% of polyethylene glycol ether.

Embodiment 2

[0021] Select qualified copper pipe blanks after series stretching, put the copper pipe blanks into the coil drawing machine, inject lubricating oil into the inner wall of the copper tube, so that the inner wall of the copper tube is covered with lubricating oil; start the machine to pull Stretching; After the stretching is completed, the copper tube enters the online annealing process for direct annealing. After the annealing is completed, the inner thread is formed. The lubricant used in the above steps is composed of: 60-80% of naphthenic base oil, 10-30% of polyalphaolefin, and 10-20% of polyethylene glycol ether.

Abstract

The invention discloses a copper pipe processing technology, which comprises the following steps: selecting a copper pipe billet stretched in series; putting the copper pipe billet into a coil drawing machine, injecting lubricating oil into the inner wall of the copper pipe, and drawing Stretching; after the stretching is completed, the copper tube is finished and wound; annealed; the finished product is put into storage. The processing technology of the invention eliminates the generation of cleaning waste liquid and waste, improves production efficiency, and realizes high efficiency, cleanness and environmental protection in the production process of copper pipes.

Description

technical field [0001] The invention relates to the field of copper pipe processing, in particular to a copper pipe processing technology. Background technique [0002] At present, in order to meet the requirements for the cleanliness of the inner wall of the copper pipe, when producing internally threaded copper pipes and various types of smooth copper pipes at home and abroad, the inner wall of the copper pipe must be cleaned with metal cleaning agents, sponges or similar media before annealing. . The commonly used processing process is to add a suitable cleaning agent and the number of sponge balls to the copper tube according to the weight of the copper tube, and then use medium-pressure nitrogen to blow the inner wall to clean the inner wall of the copper tube, anneal after cleaning, and then carry out subsequent deep processing . On the one hand, this process prevents the continuous production of the processing process, prolongs the working cycle, and reduces the pro...
