Machine Introduction

Symmetrically adjustable 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, 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.

4、 Main body organization

The main structure of the equipment consists 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. Sliding bearings are installed on the bearing seats at both ends of the upper roller. The upper roller lifting is driven by a 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, 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 active 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, etc.

4. Overturning device

It is mainly composed of a reverse handle, a flip head body, a movable hinge, etc. The function of the flipping device is to facilitate the removal of the finished product.

5. Left and right racks, base

The left and right side frames and bases are welded steel plates and undergo aging treatment after welding.

5、 Electrical control system

The equipment electrical control system consists of an electrical control cabinet and a power supply. The main switch has short-circuit protection and overload protection functions for the main motor. The forward and reverse rotation of the motor is controlled by AC contactors, and 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.

6、 Main features of the equipment

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