Mechanical Symmetry W11 8X2000MM 3 Roller Plate Bending Roll

Upper and lower rollers

upper and lower rollers are important parts of the plate bending machine, the material is 45# refined forgings, there is a machining allowance for rough turning forming, after quenching and tempering, then finishing, and finally the roller surface is quenched.

Frame

It is divided into one frame on the left and right frame. After the steel plate welded structure, after removing the welding stress, the frame is equipped with lower roller bearings. There is a square buckle screw rod inside the frame, and the upper end of the screw rod is hinged with the bearing seats at both ends of the upper roller. A worm gear pair and a screw pair are installed in the lower part. The upper roller is raised or lowered by the rotation of the nut in the worm gear.

Main transmission device

Main transmission device consists of main motor, gear reducer and brake. It can rotate forward and reverse to provide power for sheet material rolling. Both main and auxiliary reducers adopt cylindrical gear reducers. Installed on the working base together with the pad.

Unloading balance device

Unloading balance device installed on the side of the reducer to balance the upper roller during unloading.

Overturning mechanism

Overturning mechanism installed on the inverted head side for the inverted head’s turnover and recovery.

Base

It is an integral base, which is easy to install and lift. It is welded by section steel and steel plate, and has undergone stress removal treatment. Mount the frame, reducer, motor, etc. on it to form a whole.

Electrical part

Electrical part using a three-phase 380 V/50 Hz AC power supply, a main motor drives the lower roller to rotate, and a secondary motor drives the upper roller to lift. The control appliances of this machine are all installed in the control box with short circuit and overheat protection. The electric cabinet can be placed according to operation needs, and the operation is convenient.
