The profile bending machine adopts electromagnetic force clamping so that the pressing plate can be made into a variety of workpiece requirements, and it can process workpieces with sidewalls, and the operation is very simple.

What are the precautions for using the hydraulic bending machine?

The center of gravity of the whole hydraulic bending machine is relatively high, and the front is heavy and the rear is light. Therefore, you must pay attention to the position of the center of gravity during the lifting, handling, and installation process to avoid the hydraulic bending machine turning over. When lifting, the angle of the lifting wire should be as small as possible to ensure the accuracy of the machine constant!

 

What is the advantage of a profile bending machine?

Profile bending machine control the oil pump directly, bringing fast braking and substantially improved production efficiency;

Servo motor may stop if flow or pressure is unneeded, which reduces noise and energy consumption so that working environment gets better and operating costs are minimized;

Low heat balance temperature lowers the risk of oil leakage, no need for a cooling device, nor traditional bulky oil tank, highly stable, hydraulic system and oil cylinder will last for a longer time.

 


How to adjust the profile bending machine?

1. Adjustment of the upper limit of the slide block: adjust the position of the hit block Ⅱ, the profile bending machine can make the rising slide block stay at the required top dead center position, which can shorten the stroke interval of the slide block, reduce the working cycle time, and increase consumption Rate.

2. Adjust the gap between the upper and lower molds (the slider must stop at the top dead center).

a. Operate the button on the button box at the bottom right of the workbench and operate in the direction indicated by the label. The initial adjustment gap should be greater than the plate thickness, and the gap should be trimmed according to the angle of the folded workpiece. The handwheel can also be used to stop the fine adjustment. The adjustment value is displayed by the calculator. Each increase or decrease of a single digit is 0, 1mm (0, 1mm/revolution).

b. If the two ends of the workpiece angle are not divergent, you can loosen the nails, move the connecting rod to the left, disconnect the left and right rotation, turn into the handwheel (up or down) to change the interval of one end of the mechanical limit, and achieve fine adjustment The purpose of the angle of the workpiece end. Note: After adjusting, set 18 back to profile bending machine’s position and tighten the supporting nails, otherwise a mechanical accident will occur.

c. If the two ends of the workpiece angle are divergent, and the middle angle (large or small) is not divergent, this allows the upper mold to be fine-tuned and installed. When fine-tuning is used, the upper mold is close to the lower mold slot, and the middle-upper mold connection template and adjustment block are slightly relaxed. The upper screw, (the upper mold does not fall as a guideline) and then the upper adjustment block of the middle section (slightly knock left or right). In the center of the small middle angle, make the upper die protrude appropriately, tighten the supporting nails, and try to fold until the full-length angle of the workpiece reaches the allowable value.

3. The adjustment of the bending force of the hydraulic press brake: calculate the kN value of the sheet bending force in the table or according to the bending force calculation formula, and calculate the indicated pressure P-value according to Table 1, and then adjust the relief valve 8 With the handwheel, the force generated by it is slightly larger than the kN value of the folded plate.

 

Because of its simple operation and high efficiency, the profile bending machine is very popular in the international market, and the demand is increasing every year.
