AI Technical Summary

Technical Problem

In existing hot forging press die height adjustment devices, the drive unit is mounted on the slide block, which is susceptible to strong vibrations and has poor reliability. Furthermore, there is a lack of effective adjustment detection and limit control methods, resulting in insufficient equipment stability and safety.

Method used

The drive mechanism is detached from the slider and fixed independently to the machine body. The vertical movement of the slider is achieved through the cooperation of the eccentric transmission mechanism and the telescopic rod assembly. Combined with the detection mechanism for real-time monitoring and limit control, vibration is avoided and precise adjustment amount is displayed.

Benefits of technology

It significantly reduces motor wear and seal aging issues, improves equipment stability and safety, and ensures precise adjustment of mold height and long-term reliable operation.

Abstract

A device and method for adjusting the die height of a hot forging press, belonging to the field of press technology, is disclosed. The device includes a slider and a drive mechanism. An eccentric transmission mechanism is installed inside the slider. The drive mechanism is fixedly mounted on the press body via a bracket. The output shaft of the drive mechanism is connected to a telescopic rod assembly via a first ball joint. The end of the telescopic rod assembly away from the first ball joint is connected to a third screw via a second ball joint. The third screw is threadedly connected to the eccentric transmission mechanism to transmit the rotational motion of the drive mechanism to the eccentric transmission mechanism, which in turn drives the slider to move vertically. The drive mechanism is detached from the slider and independently fixed to the press body, no longer moving and vibrating with the slider. This avoids the high-frequency impact loads of forging conditions, significantly reducing motor wear, loosening, and seal aging problems, and extending the service life of the drive components.
