Novel combined type horizontal roller of H-shaped steel universal mill and manufacturing method of novel combined type horizontal roller

Abstract

The invention provides a novel combined type horizontal roller of an H-shaped steel universal mill and a manufacturing method of the novel combined type horizontal roller. The roller comprises a roller ring and a roller shaft. The roller ring is detachably assembled on the roller shaft. The roller ring is sequentially divided into a left roller ring segment, a middle roller ring segment and a right roller ring segment in the axial direction of the roller shaft. The left roller ring segment and the right roller ring segment comprise side bevels, and the middle roller ring segment comprises a horizontal roller surface. The manufacturing method comprises the steps that the horizontal roller is designed; the roller ring is segmented in the axial direction of the roller shaft to obtain the leftroller ring segment, the middle roller ring segment and the right roller ring segment, the left roller ring segment and the right roller ring segment comprise the side bevels, and the middle roller ring segment comprises the horizontal roller surface; the roller shaft is fixed, and the left roller ring segment, the middle roller ring segment and the right roller ring segment are detachably assembled on the roller shaft according to a hole pattern figure; and the two ends, in the axial direction of the roller shaft, of the roller ring are provided with thrust-prevention mechanisms arranged onthe roller shaft in a sleeving manner so that the segments of the roller ring can be prevented from axially move. By means of the scheme, repairing or scraping, caused by local reasons, of the whole novel combined type horizontal roller can be avoided, the service life of the whole roller is prolonged, and the utilization rate of metal is increased.

Description

technical field [0001] The present invention relates to the technical field of steel rolling equipment, and more specifically relates to a novel combined horizontal roll of an H-beam universal rolling mill and a manufacturing method thereof, as well as an H-beam universal rolling mill with the horizontal roll. Background technique [0002] The rolling mill is the main equipment for metal rolling, and the roll is a part of the rolling mill, which is the main working part in the rolling process. During the rolling process, the rolls are in direct contact with the rolled piece, and the rolled piece is processed to realize the plastic deformation of the rolled piece. [0003] see figure 1 , The H-beam universal rolling mill includes an upper horizontal roll 4 and a lower horizontal roll 5 set up and down oppositely, and a left vertical roll 6 and a right vertical roll 7 set oppositely left and right. Since each roll will be worn during the rolling process, after rolling for a ...

AI Technical Summary

Problems solved by technology

[0005] In order to at least solve the technical problems of low roll service life, low metal utilization rate, high processing cost and high energy consumption of the rolls in the prior art, the present invention provides a new combined horizontal roll of H-beam universal rolling mill on the one hand. The manufacturing method includes: designing a horizontal roll, the horizontal roll includes a roll shaft and a roll ring; segmenting the roll ring along the axial direction of the roll shaft according to the working state of the roll, and sequentially obtaining the left roll ring segment, The middle roll ring section and the right roll ring section, the left roll ring section and the right roll ring section both include the side wall slope of the horizontal roll, and the middle roll ring section includes the horizontal roll surface of the horizontal roll; first fix well the roller shaft, and then detachably assemble the left roller ring section, the middle roller ring section and the right roller ring section on the roller shaft according to the pass pattern; The two ends of the roller shaft in the axial direction are respectively provided with thrust mechanisms sleeved on the roller shaft to prevent the axial movement of each section of the roller ring
