For some parts with stable orders and large batches in the sample stage, the process capability analysis is carried out in advance one by one. Reasonably categorize parts that are complex in structure and require a variety of mold structures for forming, long processing hours, and affect subsequent production beats and normal processing structures. Through pre-structure screening and combing and optimization of reasonable mold matching, obstacles were cleared for mass production.
In the process of bending processing, it is often encountered that it is not easy to control and position, and there are certain hidden processing hazards in the process. A single batch of large and low production efficiency of small-size parts is optimized by customizing special forming molds on the press brake. Compared with the previous hard mold processing through a press, the special forming mold is matched with the press brake, which is more flexible in mold switching, debugging, and processing links, and the return on mold investment is higher. Processing on the press brake has improved the production efficiency more significantly and the product quality is more stable, effectively avoiding the safety hazards of the previous small-size parts in the 100 Ton Hydraulic Press Brake processing process.
1. Adjustment of the slow motion of the slider of the hydraulic press brake: When the slider moves down, the collision block "I" touches the stroke switch to make the slider move slowly. The length of the slow stroke time is adjusted by the adjustable potentiometer.
2. Adjustment of the upper limit of the slider of the 100 Ton Hydraulic Press Brake : adjust the position of the striker Ⅱ, so that the rising slider can stay at the required top dead center position, which can shorten the stroke interval of the slider and reduce the working cycle time, thereby improving Consumption rate.
3. Adjust the gap between the upper and lower die of the Electric Hydraulic Press Brake 100 ton Metal Steel Bending Machine (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. You can also use the handwheel 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 rotating connection, turn to the handwheel (up or down) to change the interval of one end of the mechanical limit, and reach the fine adjustment The purpose of the angle of the workpiece end. Note: After adjusting, set 18 back to its position and tighten the support 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 the guideline) and then the upper adjustment block of the middle section (slightly knock left or right). At 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.
4. 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 calculation formula of the bending force, and calculate the indicated pressure P value according to Table 1, and then adjust the relief valve 8 With the hand wheel, the force generated is slightly larger than the kN value of the folded plate.
5. Adjust the interval of the back gauge of the hydraulic press brake: the back gauge is used for positioning in the length direction when bending the sheet. The button on the front button box controls the motor to adjust, and the adjustment value can be turned from the button box. It is read from the number table, the conversion value of the number table is 0.1mm/revolution, and there is a handwheel to stop fine adjustment.
6. The foot switch of the hydraulic press brake can make the slider move up or down, and the operation is cumbersome.
