1. The structure of the power press is simple and the price is low. But the transmission efficiency is low, about 0.65 when the slider goes down, and about 0.35 when the slider returns. The friction belt is easy to wear and needs to be replaced frequently. Strike energy is not easy to control.
2. The power press is manually operated by the workers, and the labor intensity is large, the quality of the forgings is not easy to control, and the quality of the workers is required to be high.
3. The impact energy of the electric screw press can be controlled, and the forming tolerance of the forging is small. The quality of the workers is not high, only need to set the strike energy required for forging forming, and the strike process is controlled by the computer without manual intervention.
4. Due to the control of the impact energy, the electric screw press has no excess energy released on the mold, and the life of the mold is greatly improved. According to statistics, the service life of the power press mold is generally below 4000 pieces, and the service life of the electric screw press mold is generally Over 15,000, some even exceed 50,000.
5. The electric screw press can be forged by program, and can automatically strike multiple times according to the preset multi-step energy.
6. 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 power press.
7. The electric screw press has no fixed bottom dead center, it is not necessary to adjust the height of the mold, and it is easy to change the mold. It can easily adjust the stroke height and the return position is accurate.
8. The electric screw press has a striking force display to protect the host from overload.
