Abstract

The invention relates to an inlet guiding device of a planet pipe mill. The inlet guiding device comprises a bracket and three groups of guiding rolls, wherein the three groups of guiding rolls are arranged in an equilateral triangle shape; each guiding roll is arranged on the bracket through a rotating shaft and a pair of bearings, and each guiding roll can be rotated around the rotating shaft. According to the inlet guiding device of the planet pipe mill disclosed by the invention, the three groups of guiding rolls are arranged, so that the contact area of the guiding rolls and a pipe billet is increased, and the outer surface scratch of the pipe billet can be effectively avoided.

Description

technical field [0001] The invention relates to a composition system of a planetary pipe rolling mill, in particular to an inlet guide device of a planetary pipe rolling mill, and belongs to the technical field of pipe processing equipment. Background technique [0002] The planetary pipe rolling mill is a kind of equipment that pulls out the tube blank to form a pipe. Before the tube is pulled out, it needs to support and guide the tube blank into the rolling area accurately. [0003] The entrance guide device of the prior art planetary pipe rolling mill conveys the tube blank through a row of conveying rollers arranged side by side. Due to the small contact area between the tube blank and the conveying roller, it is easy to scratch the outer surface of the tube blank, thereby affecting the quality of the product. [0004] Therefore, in order to solve the above technical problems, it is indeed necessary to provide an inlet guide device of a planetary rolling mill with an i...
