Metal rolling device with sufficient and uniform cooling function

Abstract

The present invention discloses a metal rolling device with a sufficient and uniform cooling function. The device comprises a box body, the left end wall of the box body is provided with a metal material groove with identical left and right portions, pressing roller grooves with openings facing the metal material groove are symmetrically formed in the upper and lower end walls of the left side ofthe metal material groove, roller mechanisms are arranged in the pressing roller grooves, a first bevel gear is located within a bevel gear cavity, second bevel gears symmetrically mesh with the frontand rear portions of the first bevel gear, and the ends, away from the first bevel gear, of the second bevel gears are fixedly connected with cam shafts. The cam shafts are rotationally connected with the box body, and cam mechanisms are symmetrically arranged at the ends, away from the bevel gear, of the left and right cam shafts. Cooling liquid mechanisms which are located on the upper and lower sides of the metal material groove and located on the right sides of the pressing roller grooves are symmetrically arranged on the upper and lower portions in the box body. Quick return mechanisms which are symmetric front and back are symmetrically arranged on the upper and lower sides of the metal material groove. A rolled metal material can be sufficiently and uniformly cooled, the influenceof residual stress caused by uneven cooling is reduced, and the quality and machining speed of the metal material are improved.

Description

technical field [0001] The invention relates to the technical field of metal rolling, in particular to a fully uniform cooling metal rolling device. Background technique [0002] Metal rolling is a pressure processing method in which the metal blank passes through the gap between a pair of rotating rolls, and the cross-section of the material is reduced and the length is increased due to the compression of the rolls. This is the most commonly used production method for the production of steel, mainly used to produce profiles and plates. , Pipe. [0003] The residual stress caused by uneven cooling after rolling has a certain influence on the performance of steel components under the action of external force, and the metal at this stage needs to wait for a long time for cooling due to insufficient cooling after rolling, which prolongs the processing time and reduces the efficiency. Contents of the invention [0004] Aiming at the deficiencies of the above-mentioned techno...
