Machine Introduction
This machine belongs to the mechanical transmission three roll plate rolling machine, which is used to roll steel plates into cylindrical, curved, and conical shapes.
The upper roller presses down and is driven by an attached motor through a reducer to transmit power to the worm gear, screw and nut pair, causing the plate to bend and deform. The rolling transmission is driven by the main motor through the main reducer and open gear to rotate the lower roller, and becomes the main power source during plate rolling.

四、 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 lifting of the upper roller is driven by a worm gear and worm gear, and the pressing device is powered by an attached motor. The torque is transmitted through the mechanical linkage of the reducer, worm gear and worm gear, and screw nut to move the upper roller up and down.

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 brake.

4. Overturning device

It mainly consists of a reverse handle, a reverse body, a movable hinge, 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.

六、electric control system

The electronic control system of the equipment consists of an electrical control cabinet and a power supply. The main switch has short-circuit protection and overload protection function for the main motor. The forward and reverse rotation of the motor is controlled by AC contactors, and the high-voltage control components including circuit breakers, fuses, contactors, thermal relays, buttons, switches, indicator lights, etc. are all selected from the national standard series products.

七、The main characteristics of the equipment

The equipment is made of steel plate welded parts, with high mechanical strength, high accuracy, and strong practicality. The adjustment and operation of parallelism between the upper and lower rollers are simple, and the equipment maintenance is convenient.
