How to adjust the bending force of the press brake ?

        Before using the bending machine to bend the material, you need to adjust its various data, including the bending force, the distance of the back gauge, the upper limit of the slider, the speed of the slider, and the adjustment of the upper and lower mold gaps, etc., to make it reach Actual operation requirements. How to adjust these parameters?

        Regarding the adjustment of the bending force of the press brake, it is mainly to calculate the kN value of the bending force of the sheet metal according to the calculation formula, and calculate the value of the indicated pressure P according to Table 1, and then adjust the handwheel of the overflow valve to produce The force is slightly greater than the kN value of the folded plate.

       The adjustment of the back gauge distance of the bending machine needs to be used for positioning in the length direction when the sheet is bent. The button on the front button box controls the motor adjustment. The adjustment value can be read from the revolution table on the button box. , The conversion value of the revolution table is 0.1mm/revolution, and there is a handwheel for fine adjustment.

      The adjustment of the upper limit of the slide block of the bending machine needs to be realized by adjusting the position of the striker Ⅱ, so that the rising slide block can stay at the required top dead center position, which can shorten the stroke distance of the slide block and reduce the working cycle time, thereby increasing Productivity. The adjustment of the slow motion of the slider is related to the striker I. The stroke switch is touched to make the slider perform a slow motion, and the length of the slow stroke time is adjusted by the adjustable potentiometer.

      The adjustment of the gap between the upper and lower molds in the bending machine is completed by the button on the button box at the bottom right of the operating table. Operate according to the direction indicated by the label of the bending machine. The initial adjustment gap should be greater than the thickness of the plate, depending on the angle of the workpiece. Size to trim the gap. Of course, the handwheel can also be used to make fine adjustments. The adjustment value is displayed by the calculator. Each increase or decrease of a single digit is 0.1mm. If the two ends of the workpiece angle are inconsistent, you can loosen the nails, move the connecting rod to the left, disconnect the left and right rotating connection, and turn the handwheel to change the distance of the mechanical limit at one end to achieve the purpose of fine-tuning the angle of the workpiece end.
