What are the core components and vulnerable parts of the CNC four-roller bending machine?
CNC plate rolling machine is a special equipment for plastic production and processing of plates. Because of its simple structure,
reliable work and easy maintenance, it has more common applications in the manufacture of medium and thick plate tubes. The middle roll is
a key component for production. When the cold-rolled coil bears a very large force, it will cause deflection, which will cause uneven pressure
distribution on the thick steel plate, resulting in defective products. How to reduce deflection.

The key to the current method is that the upper working roller is designed into a drum shape. In the design, the diameter of the working part of the working
roller is gradually reduced from this to the two sides. The two lower rollers of the bending machine are positive rollers. Its position is fixed, the upper roller
is a movable roller, which can move left and right, and the upper roller can be adjusted to be parallel or skewed by the clutch for the lower roller to integrate
into the whiskers of the production of circular or cone-shaped products. The three rollers are installed on the upper and lower sound cards. On the rack,
it constitutes the main body of the equipment.
The transmission device of the coiling machine is all set on the right side of the right sound card rack. The sound card rack and part of the transmission system
are set on the overall electric welding welding base, which constitutes the main body of the equipment. The rolling force produces upward tensile strain,
which happens to be offset by the middle part of the waist drum shape, which makes the upper roll foundation tend to be vertical. This type of method is
commonly used in plate bending machines and is used by most designers. Selection, although this design scheme can have a certain practical effect of compensation,
it is difficult to calculate and produce.
Primapress company adds support for the upper working middle roll. This method adds support beams and supporting rolls to the upper working middle roll.
Adjusting the height-to-width ratio of the backing roll can cause the upper working middle roll to cause a certain pre-deformation downward.
The upward deformation caused by the roll during the upper work of the coiling is exactly offset, and the purpose of compensation for the deflection value is achieved.
This type of method is mostly used to dictate the rolling machine with a large total width specification, such as ship rolling machine and crude oil storage,
transportation and storage. Production of cans.
What are the easily damaged parts of the rolling machine?
1. The sliding bearing between the lower roller and the firm seat and the overturned seat is commonly known as the composite sleeve. As usual,
we use copper alloys, which have high wear resistance. However, due to the large amount of warfare, the composite sleeve is being used. In the process,
it is relatively easy to wear. We advocate that customers do not work to refuel, increase the amount of oil on the surface, and increase the service life of sliding bearings;
2. Electrical configuration, the control system of the bending machine. It is a part of some electrical parts, and the vulnerability is visible.
However, it is usually too fine to wire, and beware of wiring errors to discard components such as relays and warriors;
3. Lead screws, worms, turbines, nuts, and the main driving force of the transmission, due to friction and more battles, they are also easy to destroy.
When leaving the factory, the company takes a lot of butter to eliminate the frictional damage and remind the customer that it is too thin.
It is usually necessary to remove the cover for about 1 month to take the proper butter.
