2. Description:

The main transmission part of this machine is composed of universal jointer, gear reducer, cycloid gearbox and hydraulic motor .When bottom straighten roller making whole elevating action , it must be adopt joint of universal jinter 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.

3. Structure Characteristics

This equipment adopts the structure of YZJ-800 mechanic straightening machine, which use the two upper rectifying wheels to straighten flange plate downward. The difference is oil cylinder replaced reducer as power source.

a. The two sides of flange plate can be rectify solely, which can control rectifying effect and make sure the straightened flange and web plates reach vertical.

b. No lifting for roller, cost reduced and convenient operation.

c. Straightened flange plate width has increased from 800 to 1000, or even more.

d. The shortcoming is automation degree is not higher than YJZ60B; the moving of upper pressing roller needs manpower, waste time and labor.
