H Beam Flange Straightening Machine for Carbon Steel Q235A/SS400

1. Specifications:

2. Description:

This H beam flange straightening machine is widely used in welding works for the purpose of correction of the steel flange and straightening the flange plates. In the working process, when the H beam is in the process of welding and heating, the flange plate must be bent and deformed. This flange straightening machine has a large scope of application and powerful working capacity. 

The machine is composed of machine machine, roller conveyor and electrical control system. The machine is composed of base, upper frame, upper straightening roller mechanism, upper frame moving device and main transmission mechanism.

The base and the upper machine frame are welded by plate and section steel, and then do the process of stress relief.

Upper straightening roller is the main part for doing straightening work, it is composed of upper press roller, straightening shaft, shaft box, down press screw-bar, bevel gear and motor speed reducer. The material of upper roller is 35CrMo, the wear risistance has been improved after the process of heat treatment and grinding. The contact part, where the bottom of the screw-bar and the shaft box, is sphere structure. It can aviod the influence of shaft box to the screw-bar.

The relationship of flange thickness and width is as following chart:
