Comparison of the advantages and disadvantages ...

1. The friction press has a simple structure and low price. However, the transmission efficiency is low, the slider is about 0.65 when going down, and the slider returning is about 0.35. Friction belts are prone to wear and need to be replaced frequently. Strike energy is not easy to control accurately. The electric screw press's striking energy can be precisely controlled, and the forging forming tolerance is small.

2. The friction press relies on the manual operation of the workers, the labor intensity is large, the quality of the forgings is not easy to control, and the quality of the workers is relatively high. The electric screw press has low requirements on the quality of the workers. After setting the required striking energy for forging forming, the computer controls the striking process without manual intervention.

3. The electric screw press can accurately control the striking energy, and no excess energy is released on the mold. The life of the mold is greatly improved. According to statistics, the life of the friction press die is generally below 4,000, while the life of the electric screw press is generally They are all over 15,000 pieces, and some even exceed 50,000 pieces.

4. electric screw press can be programmed for forging, can automatically hit multiple times according to the preset multi-step energy.

5. When the slider of the electric screw press is stationary, the motor does not work and the power consumption is low. More than 20% power saving than friction presses.

6. the electric screw press has no fixed bottom dead center, no need to adjust the mold height, easy to change the mold. It is easy to adjust the stroke height and the return position is accurate.
