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.
