The invention discloses a closed height compensation device of a die forging machine, which has the working principle that: the hydraulic motor drives the spline shaft to rotate to drive the driving gear on the spline shaft to rotate, the convex driven gear in meshing transmission with the driving gear rotates, then the convex driven gear rotates to drive the worm connected with the convex driven gear to rotate, the eccentric worm gear is in meshing transmission with the worm, the worm transmission is provided for the eccentric worm gear inside the die forging machine slider, and the change of the die forging machine slider position is realized. Meanwhile, the rotation motion of the worm is transmitted to the encoder rotating shaft through the middle connecting shaft and the connecting sleeve. The encoder is an absolute value encoder, and is characterized in that a counter is not needed, and the absolute angle position is identified through a position sensor of an optical signal, so that the anti-interference and data reliability of the encoder can be greatly improved. The outgoing signal is directly controlled by the PLC, and digital compensation is carried out on the touch screen operation interface to realize the adjustment of the sealing height.
The closed height compensation device of the die forging machine has a simple transmission structure, utilizes an encoder digitization technology, has high precision, realizes closed height adjustment by digital compensation, and is accurate in adjustment.
According to the die forging machine sealing height compensation device, the die forging machine sealing height is directly and digitally displayed, reading on a traditional scale by naked eyes is not needed, and the device is extremely small in error, high in accuracy and strong in intuition.
In conclusion, the closed height compensation device of the die forging machine has the advantages of simple transmission structure, high accuracy and accurate adjustment.
