It's well-known that hydraulic press brake machine can only use bending mould for plate length bending processing, stamping die can only be used in power press punching machine as single mode, but if we can combine plate length bending and stamping die single molding effectively; For some products that are processed on line (such as profiles), it means that the production efficiency is several times higher. Substantial improvement in product quality; The sharp decrease in labor intensity. It has an inestimable effect on reducing the production cost.
For the products of online processing, most of them are mainly punch holes. If we can make the bending machine similar to the punching machine, it will be better.
That is to make the press brake bending machine mold unloading workbench as workbench suitable for fixed stamping die, and as long as change the mould of the waste discharge to the back side (bottom row material for machine tool under the front board, is difficult.). The press brake bending machine upper die is changed to inverted "T" type pressing plate, and then choose the suitable tonnage of machine tool, the opening height of sliding block and the length of machine tool. The solution is feasible in theory.
Make necessary adjustment to the hydraulic bending machine, mould, and other factors related:
1. Machine tool adjustment
2. Remove mould, stop gauge from plate bending machine. It could reduce the purchase cost.
3. Make another slider on the "T" type moulding board, and flip leveling. Main functions: press the mould, but should be pressed to the upper die stamping center.
4. To remove the lower die workbench, and make a widening and smooth "U" type with "T" type slot workbench. "U" type workbench main effect: limit the mould string before and after the shift, and make the mold to along the length direction of the sliding table. "T" type slot to fix mold use.
5. Make adjustable stroke block at each end of the bending machine workbench. Adjustable stroke block limit die working stroke effect and protect the mould.
6. Adjust the sheet metal bending machine stroke switch, and put time relay to the appropriate location. Bending machine stroke can be slightly greater than or equal to the adjustable stroke block, time relay must be lowered below (1s), for the purpose of improving the working frequency and get the corresponding working pressure.
7. The height of the empty stroke of the bending machine is as short as possible.
8. According to the requirements of section to choose and buy cnc press brake, take consideration of length, slider opening height, and processing tonnage; Tonnage larger than to ton and the length selected longer or equal to 1500 mm.
Mould adjustment
1. Frame with uniform size of self-made rear mold, template width shall be with the "U" type table width slip. The function of the mold is adjusted according to the requirements of the profile.
2. The mold frame guide column has a uniform length of compression spring, which plays the role of automatic bouncing after stamping.
3. The stamping die is mainly for punching hole, blanking failure mainly because of the front plate (in the center of U workbench)under the machine.
4. Discharge of material, generally used side discharge, the work process needs to pay attention to the flow smoothly.
5. Shape pressing plate shall be close to but not covered with die guide hole. In case the overstroke damage dies.
6. The lower die height must be consistent. That is, the uniform sharpener, true in the unitary, also need to use copper skin, paper almost flat. To prevent the workpiece from being deformed by stamping on the same plane.
7. The opening height needs to be consistent and the "T" type press can always be pressed on the upper plate. In order to prevent the die from spring suddenly, the top die makes the upper and lower dies out quickly.
8. Make standard accessories for convenient maintenance and replacement.
9. The material hole spacing is short, the mold is not fit, can be a mold of the porous mold, or the split hole bit punch.
10. The position arrangement on the work table should not be used to make the sliding block of the machine work, that is, the center of gravity of the sliding block of the machine tool should be the same as the punching center of the profile hole.
With the combination of hydraulic bending machine and stamping die, the production efficiency and product quality are improved. The requirement of individual quality, labor intensity and safety is irreplaceable.
