Cold bending molding machine is a sequential configuration of multi-pass molding roll, the coil, strip and other metal strip continuous transverse bending, to make a specific section profile of the plastic processing technology machinery.
1, the average force principle of each road, the entire rolling wheel average force, wear balance, prolong the service life of the roll.
2, roll using C12mov material is the use of its wear resistance, but the specific strength and hardness is contradictory, heat treatment to use C12mov red hard, quenching, two or even three times tempering to achieve hardness. 3, the orbital arc is the core part of the rail, the first several pieces of the arc after forming, in the back of the rolling folding edge, the shape of the arc, through the roll or transverse wheel, effective tube bundle protection, otherwise, the material in the tensile process of the arc will change, R becomes a small triangle, the ball is not in the end, two
When R becomes large, the coordinate rail is shaken, the track is blurred when used, the force is uneven, the rail is deformed, and the life is shortened.
4, rolling stability problems, often encountered in the production of materials in the raceway in the left and right deflection of the problem, in fact, a single group of rollers by the asymmetric, the left side of the force, the material to the right side pendulum; the right side of the force, the material to the left side pendulum.
