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 tube manufacturing process, which comprises the following steps: selecting a copper tube blank that has been stretched in series; putting the copper tube blank into a coil drawing machine, injecting lubricating oil into the inner wall of the copper tube, and stretching ; After the stretching is completed, the copper tube is finished and wound; annealed; the finished product is put into storage. The production process 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 tube production, in particular to a copper tube production process. 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 production 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 cleaning. make. On the one hand, this process prevents the continuous production of the production process, prolongs the working cycle, and reduces product...
