[0002] Cold rolling mill is an important equipment for stainless steel seamless pipe processing. It usually consists of multiple rollers for cold rolling metal materials. These rollers can be configured and designed in different ways to meet the processing needs of various stainless steel pipes. The main function of the cold rolling mill is to roll and shape the stainless steel billet at room temperature to change its size, shape and surface quality. By gradually reducing the cross-sectional size of the material, the cold rolling mill can achieve high-quality surface finish and strict dimensional control, thereby producing high-precision stainless steel seamless pipes. The cold rolling mill usually includes components such as the feeding system, the rolling mill unit, the shaping mechanism, the cutting equipment and the discharging system. During the operation, the stainless steel billet is first pre-treated and then fed into the rolling mill unit. After multiple rolling and shaping, it finally forms a stainless steel seamless pipe with the required specifications.

[0027] Specifically, the mounting groove 6 fixes the motor 7 so that the motor 7 can operate stably. The controller 15 is electrically connected to the motor 7 so that the controller 15 can control the motor 7 to operate. The mounting groove 6 limits the threaded rod 8 so that the threaded rod 8 can rotate stably. The mounting groove 6 limits the piston 9 so that the piston 9 will not deviate when moving.

[0030] Working principle: When it is necessary to spray oil on the outside of the core rod 4 and the material, the motor 7 is started to operate, thereby driving the threaded rod 8 to rotate, and then driving the piston 9 to move to the left, so as to squeeze the lubricating liquid in the installation groove 6 and discharge it from the oil spray head 10 to the core rod 4 and the material;

[0031] When the rolling process needs to be cooled, the water pump 1303 is started to drive the delivery pipe 1304 to draw water from the collection box 1301, and then the material in the rolling process is sprayed out through the sprinkler head 1305, so that the water returns to the collection box 1301 again, and then the water is filtered through the filter net 1302, thereby forming a water circulation, and then the cooling of the rolling process is completed again through the water pump 1303.
