H-beam Hydraulic Straightening Machine

H-beam Hydraulic Straightening Machine Structure principle:

This machine is used for straightening the deformation of H beam flange plate.

The straightening principle : two upper straightening roller press two side of flange plate ,one bottom roller support the center of flange , through the pushing of oil cylinder then up-press to the center of flange that reach to straightening the deformation of flange plate.

It is composed of machine frame , upper straightening roller , web plate clamp device , assistant support roller , lift oil cylinder , bottom straight roller , main transmission part ,input/output elevating roller, hydraulic system and electrical control system .

The machine frame is the carrier of all installation parts . It adopt thick steel plate whole welding , which have good structure rigidity and beautiful shape .

The two upper straighten roller install on top side of machine frame , it adopt shaft box structure , so it have big loading capacity . There have hydraulic cylinder in shaft box , it can adjust the distance of two upper straighten roller .The upper straighten roller is composed of straighten roller , straighten shaft , shaft box and bearing. Upper roller material is 35CrMo，it is treat by quench and grinding so that have good abrasive resistance .

Web plate clamp device adopt manual positioning , the other side adopt hydraulic oil cylinder push holding , adjusting the clamp position according to web thickness ,making the web plate in the center of bottom straightening roller . There have scroll bear in web clamp wheel that keep moving when clamping , which make sure the continuous working .

Assistant support roller is a transitions when beam from roller conveyor to straightening roller. When working on the bottom straightening roller , the beam will leave away the assistant support roller.

Lift oil cylinder install under the machine frame, there have bottom straighten roller on its top. It have big cylinder diameter, so it can make big lifting force that can support the weight of the beam.

Bottom straighten roller is composed of bottom straighten roller, bearing, bearing base, joint bottom plate and guide base .Bottom roller adopt forging structure , material is 40Cr，and process by quenching and grinding . So it has good abrasive resistance and anti-bending rigidity. The bearing base is on the joint bottom plate, the bottom is connecting with piston rod of lift oil cylinder. The guide base is install on the machine frame and connect with bearing base. When guide the bottom straighten roller , it also can increase whole rigidity .

Main transmission part is composed of universal jointer, gear reducer, cycloid gearbox and large power motor .When bottom straighten roller making whole elevating action , it must be adopt joint of universal jointer and reducer .

Roller conveyor adopt hydraulic elevating roller conveyor, it also can support the beam after bottom roller lift it .

Hydraulic system is composed of hydraulic station and pipeline system. It can supply the power for lift oil cylinder , web clamp oil cylinder , shaft box moving oil cylinder and elevating roller conveyor oil cylinder .

Electrical control system is composed of electrical control box and control cable, it is not only control the forward/reverse turning of main transmission motor , but also the electromagnetic valve of hydraulic station. Through hydraulic station to control the elevating of lifting oil cylinder , expansion of web plate clamp oil cylinder , forward /backward of shaft box moving oil cylinder , forward /backward of elevating roller conveyor oil cylinder .
