Application of Hardware Stamping and Drawing Die Made by Die Manufacturer in Hydraulic Bending Machine

The metal stamping and drawing dies of die manufacturers are widely used in many fields. Now, the die manufacturers will explain in detail how the metal stamping and drawing dies are used on the hydraulic bending machine.

Generally, the metal die can only be used as a single die on the press, while the hydraulic bending machine can only use the bending die to bend the length of the sheet. If we can process the length of the bending machine and the single processing of the stamping die is an effective combination; For some online stamping products (such as aluminum profiles), this means several times of production efficiency; The product quality has been greatly improved; The labor intensity is greatly reduced. It has an inestimable impact on reducing production costs.

For online processing products, most of them are perforated. If we can make the bending machine work like a punch, we can put the lower die table of the bending machine into. Fix the worktable of the stamping die, and change the waste liquid discharge of the die to the side and back row (because of the existence of the front vertical plate of the machine tool, the lower discharge is more difficult). Change the die on the bending machine to the inverted "T" type pressing plate, and then select the appropriate machine tonnage Slide opening height, machine length. This is theoretically feasible.

However, this method requires adjustment of the hydraulic bending machine, dies and other relevant factors:

1. Machine adjustment

2. The bending machine removes the upper and lower moulds and the rear stopper. It can reduce the purchase cost of machine tools.

3. Make another "T" type upper die plate for the slider of the bending machine, and install it upside down for leveling. Main function: press the upper die, but press it to the punch center of the upper die.

4. The bending machine removes the lower mold workbench, and makes another widened and smoothed "U" type middle belt "T" type groove workbench. The main function of the "U" type worktable is to limit the forward and backward serial movement of the die and make the die slide along the length of the worktable. "T" slot is used to fix the die.

5. An adjustable travel stop is made at both ends of the bending machine workbench. The adjustable stroke stop plays the role of limiting the working stroke of the mold and protecting the mold.

6. Adjust the travel switch and time relay of the bending machine to the proper position. The stroke of the bending machine must be slightly greater than or equal to the stroke of the adjustable stroke stop, and the time relay must be lowered (generally less than 1s) to increase the working frequency and obtain the corresponding working pressure.

7. The empty stroke height of the bending machine shall be as short as possible.

8. The length of the machine tool, the opening height of the machine tool slider, and the tonnage of the machine tool shall be selected according to the requirements of the profiles; The tonnage is generally greater than or equal to 40T, and the length is greater than or equal to 1500mm.
