In order to avoid the distortion of cold-formed steel machinery, the calculation of the neutral layer in the deformation zone is accurate, the material calculation in the deformation zone is accurate, and the symmetry of the roller processing is good;
The non-deformable area should be free from pressure as much as possible, and the gap between the upper and lower rollers should be kept consistent during assembly; and before the material bites in, the guide slope should be set according to the previous rolling state, and the material will slide smoothly in the roller before it is stably under pressure .
The processing accuracy of the roller of cold-formed steel machinery is the key. For this reason, a special tool is specially made to inspect it under a projector and magnify it by 20 times. The main transmission side adopts roller tapered bearings to ensure that the radial runout of the main shaft is within 0.04MM, and the main shaft will not move left and right.
