Points to note when bending the profile bending machine
Profile bending machine is also called profile rolling machine. It can be divided into two types: flat bending and vertical bending. It is an ideal equipment for bending flat steel, square steel, round steel, angle steel, I-shaped steel, H-shaped steel, square tube, rectangular tube, round tube and other profiles.
Working principle of profile bending machine
The profile bending machine is an arc-down adjustment profile rolling machine. The two side rollers of the machine are the main drive rollers, and the three working rollers can also be the main drive rollers. The upper roller position is fixed, and the two side rollers move up and down in an arc around the fixed rotation center. Hydraulic control and displacement LCD display are conducive to controlling the profile forming process. There are roller devices on both sides, which are conducive to ensuring the rolling quality of asymmetric cross-section profiles.
Points to note when bending the profile bending machine
- Fix the upper die first, so that the center of gravity of the die and the center of the pressure head are in a straight line; the upper and lower die planes must match closely and evenly, and check that the upper die has sufficient travel.
- Start the profile bending machine, test the pressure, check whether there are any abnormal conditions, and whether the lubrication is good. For workpieces that are difficult to remove from the mold, add some lubricant or lubricating oil to reduce friction and make it easier to demold.
- Before formal bending, it is necessary to check again whether the workpiece number and size are consistent with the drawing, and whether the blank has burrs that affect the pressing quality. For workpieces with large batches, it is necessary to install a stopper that can adjust the positioning. If deviation is found, the stopper position should be adjusted in time.
- It is forbidden to take and place workpieces directly on the mold of the profile bending machine by hand. For larger workpieces, they can be taken and placed outside the mold. For workpieces smaller than the mold, other tools should be used for taking and placing.
Conclusion
The profile bending machine has a reasonable structure, stable performance, and significant energy-saving and material-saving effects. It is an ideal profile bending equipment.
