Description

technical field [0001] The invention belongs to the technical field of cold-rolled pipe mills, and in particular relates to a buffer and damping device for a crankshaft transmission system of a cold-rolled pipe mill. Background technique [0002] The cold-rolling mill is a process equipment for cold-rolling raw pipes by using ring holes. This machine has good blanking performance, and can also roll non-ferrous metal seamless pipes with ordinary precision. The biggest feature of the cold-rolled pipe mill is the high material utilization rate, and the precision and surface roughness are better than cold-drawn pipes. [0003] The existing cold-rolled pipe mill cannot complete the processing at one time. It is necessary to use a rotary mechanism to rotate the tube blank, so as to reprocess the tube blank. The processing efficiency of this processing method is low, and the rotary mechanism is running. A large vibration will cause the cold-rolled pipe to vibrate and reduce the q...
