The roll in the cold-formed steel machine is a very important part, and its design also reflects its uniqueness.
Each pass of the roll in the cold-formed steel machine should be evenly stressed so that the wear can be balanced, thereby prolonging the service life of the roll.
Generally, the roll is made of C12MoV material, because this material has good wear resistance, but attention should be paid to the relationship between hardness and strength, so it must be handled properly.
The upper and lower rollers or horizontal wheels should be effectively protected by tube bundles, otherwise problems will easily occur during use. For example, the track will be blurred, deformed, etc., and the force will be uneven, which will shorten its service life. During the rolling process of cold-formed steel machinery, the rolling stability must be considered. If the material is deflected left and right in the raceway, then we have to take corresponding measures.
For example, it is possible to keep the gaps in each area of the roller consistent during assembly. And before the material bites in, the guide bevel can be set, so as to avoid this problem. In the production process, if there is bending and twisting, the main reason is that the force is unbalanced, so we should balance the force in the design so that the processing can be accurate.
