Description

Closed height compensation device of die forging machine

Technical Field

The invention relates to a closed height compensation device of a die forging machine, which can be widely applied to the die forging machine.

Background

According to an existing die forging machine sealing height adjusting system, a lead screw and a nut are used for transmission, a pointer moves linearly, and sealing height adjustment is achieved according to scale reading of the pointer on a scale. The transmission structure of traditional technique is complicated, and the reading is marked by the mechanical scale, has great error, and the accuracy is low, has more not realized the digital adjustment.

Disclosure of Invention

The invention aims to provide a die forging machine sealing height compensation device which is simple in transmission structure, high in accuracy and accurate in adjustment.

In order to achieve the above object, the closed height compensation device of the die forging machine of the present invention comprises a hydraulic motor mounted on the side of a die forging machine slide block through a fastening bolt, a spline shaft located in a die forging machine slide block hole and mounted on the hydraulic motor, a driving gear mounted on the middle portion of the spline shaft, a tail bearing located between the tail of the spline shaft and the die forging machine slide block hole and mounted on the die forging machine slide block hole, a convex driven gear in meshing transmission with the driving gear, a worm rod located in a die forging machine slide block horizontal hole and having one end connected with the convex driven gear, an eccentric worm wheel mounted in the die forging machine slide block hole and in meshing transmission with the worm rod, an intermediate connecting shaft mounted inside the central hole of the tail end of the worm rod and rotating with the worm rod, a coupling sleeve connected with the intermediate connecting shaft through a left fastening bolt and functioning, the encoder is connected with the support plate through an encoder fastening bolt, the flange sleeve is connected with the support plate through a flange sleeve fastening bolt and used for supporting and positioning the encoder, and the encoder rotating shaft is connected with the connecting sleeve through a right fastening screw.

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.
