When the roll forming machine is working, push the profile steel to be processed by the roll forming machine between the two active rollers by the door bracket of the auxiliary system, and start the hydraulic system to make the hydraulic cylinder push the dovetail groove and the cold-formed roller to cold-press the profile steel. , When the required radian is reached, the hydraulic system is turned off, and the mechanical transmission system is started, so that the driving roller rotates and drives the profile steel to move forward smoothly and slowly depending on the friction force, so as to realize the continuous cold bending operation.
Twisting solution of roll forming machine:
1. The calculation of the neutral layer in the deformation zone is accurate, the calculation of the material used in the deformation zone is accurate, and the roller processing symmetry is good.
2. The non-deformed area should not be pressed as much as possible (such as the bottom of the slide rail), and the gap between the upper and lower rollers should be consistent during assembly.
3. Before the material is bitten, the guiding inclined opening should be set according to the rolling state of the previous road. Before the material is stably pressed, the material slides smoothly in the rolling.
4. The accuracy of the roller processing is the key. For this reason, a special tool is specially made under the projector and magnified 20 times for inspection.
5. On the main transmission side, the roller taper bearing is used to ensure that the radial runout of the main shaft is within 0.04MM and that the main shaft will not move left and right. There is a gap in the ordinary ball bearing itself, and the axial movement cannot be avoided in the precise transmission.
6. The problem of bending and twisting in production is mainly caused by unbalanced force, unbalanced left and right force, left and right bending, unbalanced upper and lower force, resulting in distortion. Solution: The design is balanced in force, accurate in processing, and convenient in installation and adjustment.
At the end of the cold bending work, close the transmission system of the bending machine, and start the hydraulic system at the same time, so that the hydraulic cylinder is retracted. Simply place the cold-formed steel on the door bracket of the auxiliary system.
This cold bending forming machine operation not only ensures the strength of the material, improves the quality of the supporting steel arch, greatly improves the work efficiency, and the operation steps are simple and easy to understand.
