Problems solved by technology

Existing cold-rolled pipe mills usually use steel cam rows to guide the tube embryos. The distance between the cams cannot be adjusted, and the tube embryos are prone to fall off during the guiding process, causing workers to be injured.
In addition, this kind of cam is also easy to wear, and the noise is also very loud

Abstract

The invention discloses a tube blank guiding device of a tube cold-rolling mill. The tube blank guiding device of the tube cold-rolling mill comprises a fixed pin shaft, the middle of the fixed pin shaft is provided with a suspension rack, the suspension rack is provided with an adjusting long through hole, both ends of the fixed pin shaft are respectively provided with an adjustable fixing ramp board, the middle of the bottom of each adjustable fixing ramp board is provided with a pair of fixing wheel shafts which are provided with detachable guide cams. According to the tube blank guiding device of the tube cold-rolling mill, by means of the adjustable fixing ramp at both ends of the fixed pin shaft, a user can adjust the gap between the fixing ramp boards according to the size of a tube blank and accordingly change the distance between the guide cams, so that dropping of the tube blank can be effectively avoided and the guiding speed can be improved. Besides, both ends of the bottom of each fixing ramp board are provided with limiting bends and can automatically scrape impurities on the surface of the tube blank. The tube blank guiding device of the tube cold-rolling mill is compact in structure, easy to assemble and high in practicality.

Description

technical field [0001] The invention relates to a pipe-making equipment, more precisely, a pipe blank guiding device 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. It has good blanking performance and can also roll non-ferrous metal seamless pipes with ordinary precision. Existing cold-rolled pipe mills usually use steel cam rows to guide the tube embryos. The distance between the cams cannot be adjusted, and the tube embryos tend to fall off during the guiding process, causing workers to be injured. In addition, this kind of cam is also easy to wear, and the noise is also very loud. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a pipe blank guiding device of a cold rolling mill. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technica...
