Rolls design and manufacturing features of cold bending machine

Understanding of cold bending machine, although there are some in front, but not very much, not enough to summarize the cold bending machine. Therefore, we have to continue to understand that we cannot stand still, or we will fall behind. Based on the above reasons, we will continue to explain the knowledge of cold bending molding machine, so as to achieve this goal.

The roll in the cold bending machine is an important part. Its design and manufacturing features are as follows:

(1) Each pass shall be evenly stressed so as to wear evenly and extend the service life of the roll.

(2) Generally, GCr15 material is used for roller, because this material has good wear resistance, but attention should be paid to the hardness and strength, so it should be handled properly.

(3) The upper and lower rollers or horizontal wheels shall be protected by effective tube bundle, otherwise, problems may occur in the use process. For example, the track of the slide rail will be fuzzy, deformed and other phenomena, and the force will be uneven, so as to shorten its service life.

(4)In the rolling process of the cold bending machine, the rolling stability should be considered. If the material is skewed to the left and right in the raceway, then we should take corresponding measures. For example, when assembling, keep the gap in each area of the roller consistent. And before the material is bited in, the guide ramp can be set to avoid the problem.

(5) In the production process, if there is bending and twisting phenomenon, the main reason is the unbalanced force, so we should balance the force in the design, so as to be able to process accurately.
