According to the Metal Profile Roll Forming Machine Factory, when the roll forming machine is working, the steel profile processed by the roll forming machine is pushed between the two active rollers by the gantry bracket of the auxiliary system, and the hydraulic system is activated to make the hydraulic cylinder Push the dovetail groove and cold-bent rollers into cold-pressed steel. When the required arc is reached, turn off the hydraulic system and start the mechanical transmission system to make the active roller rotate and rely on friction to drive the steel to move forward slowly and smoothly, thereby achieving continuous cold bending.
Rolling Molding Machine distortion solution:
1. Accurate calculation of neutral layer in deformation zone, accurate calculation of materials used in deformation zone, and good symmetry of roller machining.
2. The non-deformed area should not be compressed as much as possible (such as the bottom of the slide rail). During assembly, the gap between the upper and lower rollers should be consistent.
3. Before the material bites in, the guide bevel should be set according to the state of the previous rolling, before the material is stably pressed, the material slides smoothly in the roller.
4. The accuracy of the roller processing is the key. For this purpose, special tools are specially made under the projector, which are magnified by 20 times for testing.
5. The main drive side adopts roller cone bearings to ensure that the radial runout of the main shaft is within 0.04MM and to ensure that the main shaft will not move left and right. There is a gap in the ordinary ball bearings, and axial movement cannot be avoided in precise transmission.
6. The problem of bending and twisting in production is mainly caused by unbalanced force. The left and right forces are unbalanced, the left and right bending, and the up and down forces are unbalanced, causing distortion. Solution: Balanced design force, accurate processing, and easy installation and adjustment.
Steel Door Frame Roll Forming Machine
At the end of the cold bending work, turn off the transmission system of the bending machine and start the hydraulic system at the same time to make the hydraulic cylinder retract. Place the cold-formed steel on the door bracket of the auxiliary system.
The operation of this cold bending and bending machine not only ensures the strength of the material, but also improves the quality of the supporting steel arch frame, greatly improving the work efficiency, and the operation steps are simple and easy to understand.
