High-speed rolling mill

Abstract

The invention discloses a high-speed rolling mill, and belongs to the field of pipe machining equipment. According to the high-speed rolling mill, the machining speed of a pipe is improved. The high-speed rolling mill comprises a frame, a rolling machine head installed on the frame and used for rolling the pipe, a core rod arranged on the frame and used for guiding pipe conveying, a core rod supporting piece arranged on the frame and used for supporting the core rod, a pipe supporting piece arranged on the frame and used for supporting the pipe, a jacking trolley slidably arranged on the frameand used for pushing the pipe to be conveyed to the rolling machine head, and a plurality of core rod holding devices used for limiting the axial displacement and the radial displacement of the corerod during conveying and machining the pipe. The jacking trolley can push the core rod supporting piece so that the core rod supporting piece can overturn in the axial direction of the pipe, and eachcore rod holding device comprises a clamping jaw capable of clamping or loosening the core rod, and a lifting oil cylinder for controlling the lifting of the clamping jaw, so that the influence on themovement of the jacking trolley is avoided.

Description

【Technical field】 [0001] The invention relates to the field of pipe material processing equipment, in particular to a high-speed rolling mill. 【Background technique】 [0002] When the pipe is rolled, the head of the rolling mill usually drags the pipe while processing. The processing speed of the pipe is low. If the head produces a large traction force on the pipe, the quality of the pipe will be affected during the rolling process. . For this reason, the feeding speed of the pipes on the frame can be increased, but it is necessary to keep the pipes stable during the feeding process. 【Content of invention】 [0003] The technical problem to be solved by the invention is to overcome the deficiencies of the prior art and propose a high-speed rolling mill to increase the processing speed of the pipe. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A high-speed rolling mill ...
