Saint Fighter (Shandong) Machinery Co., Ltd.

1.Symmetrical up regulation three roll plate rolling machine
This machine belongs to the mechanical transmission three roll plate rolling machine, which is used to roll steel plates into cylindrical, arc-shaped, and conical shapes.
The upper and lower rollers transmit power through hydraulic motors, hydraulic cylinders, and hydraulic stations, causing bending deformation of the sheet metal. The rolling drive is driven by the main motor through the main reducer and open gear to rotate the lower roller, and becomes the main power during the rolling process.

2.Main body
The main structure of the equipment is composed of an upper roller device, a pressing device, a lower roller device, a main transmission device, a flipping device, left and right side frames, and a base.
（1）Upper roller device and pressing device
The upper roller device consists of an upper roller, an upper roller bearing seat, etc. Install sliding bearings on the bearing seats at both ends of the upper roller. The upper roller lifting is driven by hydraulic cylinders, and the power is provided by the hydraulic station. The pressing device is powered by a hydraulic motor.
（2）Lower roller device
The lower roller device consists of a lower roller, a lower roller bearing seat, a lower roller gear, and sliding bearings. The lower roller is the driving roller, and the gear on the output shaft of the main transmission reducer drives the lower roller gear to transmit torque to the lower roller.
The material of the upper and lower rollers is 45 # steel, and the processing sequence is rough machining, quenching and tempering, precision machining, and surface heat treatment
（3）Main transmission device
The main transmission device consists of a main motor, a gear reducer, and a hydraulic station.
（4）Overturning device
Mainly composed of hydraulic station, hydraulic motor, inverted body, flipping handle, etc., the function of the flipping device is to facilitate the removal of finished products.
（5）Left and right side racks and bases
The left and right frames and bases are made of steel plate welded parts, which are subjected to aging treatment after welding.
