Background

The cold rolling deformation processing of the seamless steel pipe is to convey a blank pipe into a rolling deformation tool through mechanical power, perform metal deformation processing on the blank pipe of the seamless steel pipe through a closed circular ring space (consisting of a plurality of continuous closed circular rings with different diameters from large to small) formed by a pass arranged on a roller device and a top arranged at the front end of a mandrel, change the physical state of metal (usually reducing deformation) through extrusion (rolling), the change degree (the outer diameter, the inner diameter, the wall thickness and the like of the steel pipe) depends on the size of the deformation tool, and a plurality of deformation processing modes can be adopted when the deformation amount is large until the appearance and the technical requirements of a finished product pipe are met.

In the process of cold rolling steel pipes, a rotary feeding mechanism is required to drive the steel pipes to rotate through the core rods in each extrusion (rolling) process, so that the aim of uniformly rolling all parts of the steel pipes is fulfilled. At present, most of the existing full-automatic cold pilger mills have certain deviation between the rotation frequency and the roller frequency, and have certain influence on the quality of pipe materials.

Most of steel tubes fed by the cold-rolling steel tube mill have straightness deviation, most of the existing full-automatic cold-rolling steel tube mills do not have a deviation correcting device, and the follow-up deviation correction consumes working hours. Therefore, a new type of fully automatic cold pilger mill is needed to overcome the above-mentioned drawbacks.
