What is Steel Plate Rolling Machine?

The steel plate rolling machine is a device that uses work rolls to bend and shape the sheet metal. It can form parts with different shapes such as cylindrical parts and tapered parts. It is very important for processing equipment. The working principle of the sheet metal roller for sale is to make the work roll move by the action of external forces such as hydraulic pressure and mechanical force so that the plate is bent or formed by bending. According to the rotational movement and position change of work rolls of different shapes, elliptical parts, arc parts, cylindrical parts, and other parts can be processed.

Working principle

The upper roller which is in the symmetrical position of the center of the 2 down rollers of plate rolling machine, can provide a torque of bending plate, by the hydraulic oil in the hydraulic cylinder acts on the piston for vertical movement. The flat plastic metal plate of the metal rolling machine for sale passes between the three work rolls (two lower rolls and one upper roll) of the plate rolling machine, and the metal plate passes through multiple passes by the lower pressure of the upper roll and the rotational movement of the lower roll Continuous bending (the inner layer is compressed and deformed, the middle layer is unchanged, and the outer layer is stretched and deformed), resulting in permanent plastic deformation, rolled into the required cylinder, cone or part of them.

Structural features

The automatic feeding equipment of the steel plate rolling machine is mainly composed of a plate trolley, an actuator, a plate transmission mechanism, and an auxiliary mechanism. The sheet trolley is used to place the sheet to be rolled. The main function of the actuator is to transport the plate to be rolled on the sheet trolley to the feeding platform. The plate's handling operation is mainly applied to the rectangular coordinate manipulator and vacuum suction cup pick-up device. In industrial automation systems, it is often necessary to pick up and transport workpieces. Vacuum suction cups are widely used as suction cup robots.

The transmission methods of the rectangular coordinate manipulator mainly include mechanical transmission (gear and rack transmission, synchronous belt transmission, ball screw transmission), linear motor transmission, and pneumatic transmission. The sheet material transmission mechanism is mainly used to transmit the sheet material to be rolled, and the roller shaft transmission and the universal ball transmission are common. The main function of the auxiliary mechanism is to improve the accuracy of sheet rolling. Common auxiliary mechanisms include a sheet center alignment device, pushing device, and displacement detection device.

Classification

Due to the different fields of use, the sheet metal rolling machines for sale is also different. It is divided into a 3 roller plate rolling machine and four-roller plate rolling machine from the number of rollers. The 3 roller is divided into a symmetrical 3 roller plate rolling machine, a horizontal downward-adjusting 3 roller plate rolling machine, an arc downward-adjusting plate rolling machine, an upper-roller universal 3 roller plate rolling machine and a hydraulic numerical control plate rolling machine. From the transmission, it is divided into the mechanical plate rolling machine and hydraulic rolling machine. In terms of the development of the plate rolling machine, the universal type of the upper roller is the most backward, the horizontal downward adjustment is slightly advanced, and the arc downward adjustment is the most advanced.

The 3 roller plate rolling machine has a mechanical and hydraulic rolling machine.

1. The mechanical 3 roller rolling machine is divided into symmetric and asymmetric.

A. Mechanical 3 roller symmetrical steel plate rolling machine

Performance characteristics: The structure of the steel rolling machine is a 3 roller symmetrical type. The upper roller is vertically moved at the symmetrical position of the center of the two lower rollers. Rotating motion, through the output gear of the reducer, meshes with the lower roller gear to provide torque for the rolled sheet. The disadvantage of this machine is that the end of the sheet needs to be pre-bent by other equipment.

B. Mechanical 3 roller asymmetric steel plate rolling machine

Performance characteristics: The structure of the sheet metal rolling machine is a 3 roller asymmetrical type. The upper roller is the main drive, and the lower roller moves vertically to clamp the plate and mesh with the upper roller gear through the lower roller gear, at the same time as the main drive; the side roller for tilting movement, with dual functions of pre-bending and rolling. The machine has compact structure, easy operation and maintenance.

2. Hydraulic 3 roller symmetrical rolling machine

Performance characteristics: the upper roll of the machine can be vertically lifted. The hydraulic drive for vertical lifting is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston rod. The lower roller is driven by rotation and meshed with the output gear of the reducer to provide torque for the coil plate. The lower roller has a supporting roller and can be adjusted. The upper roller is in the shape of a drum, which improves the straightness of the product and is suitable for cans of various cross-sectional shapes with extra-long specifications.

The upward-adjusting symmetrical three-roll plate rolling machine can roll metal plates into the circular, arc, and conical workpieces within a certain range. The two lower rollers of this hydraulic rolling machine are driving rollers, and the upper roller is driven rollers. Steel plate roller is widely used in shipbuilding, boiler, aviation, hydropower, chemical industry, metal structure, and machinery manufacturing industries.

The hydraulic plate bending machine is suitable for the bending and deformation of metal plates. It can roll around, arc and conical workpieces within a certain range, and has the function of pre-bending the end of the plate. The hydraulic rolling machine can be moved horizontally. The upper roller is driven roller and can move up and down. The moving methods are mechanical and hydraulic. The transmission shafts are connected by universal couplings.
