Features of Cold roll forming machine design and manufacturing process:

  1. The principle of average force for each pass is that the average force of the entire wheel is balanced, wear is even, and the service life of the roll is prolonged.

  2. The orbital arc is the core of the slide rail, and the arc positions after the first several presses are formed. In the next time, the circular arc is formed and the formed circular arc is protected by the upper and lower rollers or the horizontal wheel.

  3. Rolling stability problems, often encountered in the production of materials in the raceway around the issue of deflection, in fact, is a single wheel by the asymmetry, the left side of the force, the material to the right side swing; the right side of the force, material Swing to the left. The solution is:

  a: The calculation of the neutral layer in the deformation zone is accurate, the calculation of the material in the deformation zone is accurate, and the symmetry of the roller processing is good.

  b: The non-deformation area is not pressed as much as possible (such as the bottom of the slide rail), and the gaps between the upper and lower rollers in the assembly are kept the same during assembly.

  c: Before the material bites into, according to the rolling state of the front road, the guiding inclined mouth should be set. Before the stable pressure, the material slides smoothly in the rolling.

  4. The problem of bending and twisting in production is mainly caused by unbalanced force, left and right force imbalances, left and right bending, unbalanced forces from top to bottom, and distortion. Solution: Balanced force design, accurate processing, easy installation and adjustment.

 5, the accuracy of the wheel processing is the key, for this purpose, special tools for the production of a special projector under the magnification of 20 times for testing.
