1. Definition of the cold roll forming machine

The cold roll forming machine is a machine that continuously bends sheet metal, coils, strips and other metal plates and strips horizontally through multiple-pass forming rolls arranged in sequence to form a plastic processing technology for specific cross-section profiles.

In English: cold roll forming machine

Other names: roll forming machine

How to use: Multi-pass forming rolls arranged in sequence

Object: sheet metal, coil, strip and other metal strip

Category: Processing Technology

Significance: New processes and technologies that save materials, energy, and efficiency

2. Cold roll forming machine - design of slide rail machine roll

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

b: The non-deformed area should not be stressed as much as possible (such as the bottom of the slide rail), and the gap between the upper and lower rollers should be kept consistent during assembly.

c: Before the material bites in, the guide slope should be set according to the rolling state of the front track, and the material will slide smoothly in the roll before the stable pressure.

d: The problem of bending and twisting in production is mainly caused by unbalanced force, unbalanced force on left and right, bending left and right, unbalanced force on top and bottom, resulting in distortion. The solution is to balance in force when design while the processing should be accurate, and the installation and adjustment be convenient.

e: The accuracy of the roller processing is the key. For this purpose, special tools are made to detect under the projector and magnify 20 times.

f: The main drive side adopts roller cone bearings to ensure that the radial runout of the main shaft is within and outside 0.04MM to ensure that the main shaft will not move from side to side. There is a gap in the ordinary ball bearing itself. Thus, axial movement cannot be avoided in precise transmission.

3. The important significance of the cold roll forming machine

The cold roll forming machine is a kind of material-saving, energy-saving and efficient sheet metal forming machine with new technology. Using this technology, not only can produce high-quality steel products, but also can shorten the product development cycle and improve production efficiency, thereby improving the market competitiveness of the enterprise.

In the past half century, cold roll forming has developed into the most effective sheet metal forming technology. 35% to 45% of the strip steel rolled in North America is processed by cold forming, which is more than the steel used in the automotive industry.
