Description
Technical Field
The invention relates to a hydraulic device for jacking a die forging machine, which can be widely applied to the hot die forging forming process of the die forging machine.
Background
The ejector on the die is one of special devices for ejecting materials in die forging production, and particularly one of indispensable auxiliary devices for dies for large-scale die forging machines. Because most of die forgings with concave cavities can be stuck in the upper die during forging, if the die forgings cannot be taken out in time, the production efficiency is reduced, and the performance of the die forgings is influenced. At present, the material loading device of the die forging machine generally adopts a mechanical cam type material loading device, and the principle is as follows: the connecting rod swings left and right to drive the cam to rotate to realize downward movement of the ejection beam and drive the ejection rod to move downward, so that the forge piece adhered to the lower surface of the sliding block is ejected out. However, the following problems exist:
firstly, in long-term use, because the continuous friction between cam and the liftout roof beam leads to the wearing and tearing of cam, liftout roof beam to precision when the greatly reduced liftout can not realize the liftout function even. Thus, the mould is possibly blocked or damaged, the cost is improved, and the production efficiency is reduced. Secondly, the mechanical material lifting device is complex in structure and high in processing cost. Thirdly, the structure belongs to a combined device, an ejection part of an upper die cavity is composed of an ejection plate and an ejection shaft through bolts or interference fit, and the problem of insufficient strength of a die cavity connecting part is easy to occur. Fourthly, the pneumatic material ejecting device pushes the material ejecting shaft to eject materials by means of gas. The structure is easy to cause low production efficiency due to gas discharge or insufficient pressure of the air compressor.
Disclosure of Invention
The invention aims to provide the upper material ejection hydraulic device of the die forging machine, which has the advantages of simple transmission chain, high transmission precision, flexible operation, suitability for automatic production, high production efficiency, long service life and stable material ejection effect.
In order to achieve the purpose, the hydraulic jacking device on the die forging machine comprises a jacking oil cylinder body which is convex and is arranged on the bottom surface of a sliding block of the die forging machine through a fastening bolt, a cylinder cover which is provided with an oil inlet and is arranged on the top surface of the jacking oil cylinder body, a pipe joint which is provided with an oil inlet and is arranged on the cylinder cover through threaded connection, a piston which is arranged in the jacking oil cylinder body, a jacking shaft which is arranged on the piston, a cylinder plug which is sleeved on the tail end of the jacking shaft and is arranged on a central threaded hole of the jacking oil cylinder body through threaded connection, and a return spring which is sleeved on the jacking shaft and is arranged between the piston and the.
The invention discloses a hydraulic device for ejecting material on a die forging machine, which has the following ejection working principle: during the liftout, the oil inlet of the oil inlet hole is ejected out of the liftout shaft integrated with the piston, and when the liftout is finished, the liftout shaft automatically resets through the reset spring in the hydraulic cylinder, so that the operation is flexible, and the automatic lifting device is suitable for automatic production.
Compared with the prior art, the hydraulic material jacking device for the die forging machine disclosed by the invention has the advantages that hydraulic material jacking is adopted, and the production efficiency is high.
According to the hydraulic device for pushing the material on the die forging machine, the material pushing shaft extends out of the upper die cavity only when the material is pushed and pushes the die forging piece, so that the material pushing shaft does not rub the die forging piece, and the service life of the hydraulic device for pushing the material on the die forging machine can be prolonged.
The hydraulic device for ejecting the material on the die forging machine can ensure the stable material ejecting effect for a long time because the material ejecting shaft has no friction and wear.
Compared with the traditional mechanical material ejecting mechanism, the material ejecting device on the die forging machine adopts an integrated structure of the piston and the material ejecting shaft, pushes the material ejecting shaft to eject the material in the same central axis direction, namely the power direction is consistent with the material ejecting direction, and has the advantages of short transmission chain, simple transmission chain and high transmission precision.
In conclusion, the hydraulic device for ejecting the material on the die forging machine has the advantages of simple transmission chain, high transmission precision, flexible operation, suitability for automatic production, high production efficiency, long service life and stable material ejecting effect.
