What Are the Vulnerable Parts of the Sheet metal rolls and How to protect them?

Sheet metal rolls is a special equipment for plate forming production and processing. Because of its simple structure, reliable work and easy maintenance, it is widely used in the production of medium and heavy plate cylinder. The upper working roll is the key part for production. When the bearing force in cold rolling coil is very large, it will cause deflection and uneven pressure distribution on thick plate, How to reduce the deflection caused by defective products.

The key to the current mode is that the upper working roller design scheme is waist drum shape. In the design scheme, the diameter of a part of the working roll is gradually reduced from this to both sides. The two lower rollers of the rolling machine are active rolls, and the parts of the upper roller are fixed and the upper roller is a moving roll, which can move left and right.

Depending on the clutch upper roller, the upper roller can be adjusted to a flat or slanted part, To integrate into the production of circular or cone type products, three rollers are installed on the upper and lower sound card frame to form the main body of the equipment.

The drive device of the rolling mill is set on the right side of the right sound card frame. Part of the sound card frame and transmission system is set on the overall welding welding base, which constitutes the main body of the equipment.

When the upper roll is cold rolled, the upper roller is subject to upward tension strain due to the upward rolling force, which is exactly in line with the middle part of the waist drum shape, so that the upper roller foundation tends to be vertical, This kind of method is widely used in the rolling machine, and is selected by most designers. Although the design scheme can have certain compensation effect, it is difficult to calculate and manufacture, Krrass added support for the upper working middle roll. The support beam and supporting roller were added for the upper working middle roll.

According to the adjustment of the ratio of height to width of the support roller, the upper working roll can cause certain pre deformation, which is exactly in line with the upward deformation caused by the upper working roll during cold rolling, so as to achieve the goal of compensation for deflection value, This kind of method is mainly used for the production of the plate rolling machine with a large size and overall width, such as the ship rolling machine and the crude oil storage and transportation tank.

What are the easily damaged parts of the sheet metal rolls?

1. The sliding bearing of the lower roll, the firm seat and the overturned seat is commonly known as the composite sleeve. As usual, we accept copper alloy, and its wear resistance is higher than the force. However, due to the large amount of fighting, the composite sleeve is easy to wear in the process of utilization. We encourage customers to refuel without shift, increase the oil quantity of their battle surface, and increase the service life of sliding bearing;

2. Electrical configuration is the control system of plate bending machine. As a part of some electrical parts, the vulnerability can be seen. However, the wiring is usually too detailed, so as to guard against wiring errors and discard the relay, warfighter and other components;

3. Lead screw, worm, turbine, nut, the main force of transmission, due to friction and war, is easy to destroy. When leaving the factory, the company took part in a large amount of butter, eliminated its friction damage, and reminded the customer that it was too fine. As usual, it was necessary to remove the cover and take part in the proper butter in about one month.
