Embodiment

[0024] According to the standard cross-sectional drawing of channel steel, make a single-piece roll ring 1 with corresponding thickness and slope, see figure 1 , figure 2 ; When straightening, according to the size of the channel steel model, reasonably stack and assemble the single roll ring 1 on the roll cover 2, and fix the roll cover 2 with a fastening washer 4 at the end of the roll cover 2 to limit the roll ring 1. The combined channel steel straightening roller is integrally installed on the main shaft 5 of the straightener, and then the combined channel steel straightening roller is fixed on the main shaft 5 by the hydraulic device with the roller cover 2 and the locking device. If the length of the working face of the straightening roller is not enough, a spacer can be added between the roller rings 1 for fine adjustment, and the spacer is made of a steel plate with a thickness of 1 mm or 5 mm. The chamfer angle α=6° of the edges on both sides of the roll ring 1 arr...

Abstract

The invention relates to a combined box iron straightening roller. The combined box iron straightening roller comprises an upper roller and a lower roller; each of the upper and lower rollers comprises a roller sleeve, a plurality of roller rings, and a fastening washer, wherein each roller ring is of a circular ring structure, the roller rings and the roller sleeve are fixedly connected through the fastening washer, and gaskets are arranged between the roller rings. The combined box iron straightening roller has the advantages that the manufacturing cost of the straightening roller is reduced, and the straightening quality is improved; existing box iron has a total of 10 varieties, each variety contains 10 roller rings, but by adopting the combined straightening roller, the requirements can be met only by manufacturing one set of single-piece roller rings; meanwhile, if the local of the straightening roller is damaged, the corresponding roller ring can be replaced, and the maintenancecost is reduced; by increasing or decreasing the number of the roller rings, the straightening roller can adapt to box iron with multiple models; and the outer diameter of the roller rings arranged at the two ends of the upper roller are large, the position of the box iron can be limited during box iron straightening, the deviation is prevented, meanwhile, the two sides of the ox iron can be straightened once, and the straightening efficiency is improved.

Description

technical field [0001] The invention relates to a channel steel straightening device, in particular to a straightening roller suitable for straightening various channel steels. Background technique [0002] Channel steel straightening rollers were originally used, and the corresponding straightening workers were selected according to the variety of channel steel. There are many types of channel steel, and there are 10 straightening rollers for each variety. Production costs are under great pressure. In order to solve the above problems, a straightening roller suitable for straightening various channel steels is needed. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a combined channel steel straightening roller, which adopts a combined structure to form channel steel straightening suitable for various types. [0004] To achieve the above object, the present invention is achieved ...
