Description

Multi-station ejection feeding and ejecting device

Technical Field

The invention relates to an upper material pushing device for multi-station ejection, which can be widely applied to screw presses, in particular to large screw presses.

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 rod 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 rod 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.

In order to achieve the purpose, the multi-station ejection upper ejection device comprises a hydraulic cylinder body arranged in a central hole of a sliding block, an upper oil inlet pipeline, a lower oil inlet pipeline, a piston rod, a flange plate, a baffle disc, a base, a baffle disc countersunk head bolt, a guide sleeve, a lower oil inlet pipeline, a piston rod, a baffle disc countersunk head bolt, a baffle disc countersunk head bolt, a guide sleeve and a lower oil inlet pipeline, wherein the upper oil inlet pipeline is connected with the upper end side face of the hydraulic cylinder body, penetrates through a horizontal hole of the sliding block and extends out of the side face of the sliding block, the piston rod is arranged in the piston rod, the flange plate is fixedly arranged on the outer side face of, The ejector device comprises a concave guide post, an ejector base plate and a plurality of ejector rods, wherein the concave guide post is matched with a guide sleeve and is arranged at the end part of a piston rod through a horizontally arranged connecting pin, the ejector base plate is arranged on the end face of the tail end of the concave guide post through an ejector base plate countersunk head bolt, and the ejector rods are connected with the ejector base plate through threads.

The invention relates to an upper ejection device for multi-station ejection, which is provided with 2 connecting pins.

The invention relates to an upper material pushing device for multi-station ejection, which has the working principle that: when the material is ejected, the upper oil inlet pipeline takes oil to drive the piston to move downwards, the piston drives the piston rod to move downwards, the piston rod drives the guide column to move downwards, the guide column drives the ejection chassis to move downwards, the ejection rod is driven to eject downwards, and the ejection action is finished. When the lower oil inlet pipeline takes oil, the piston rod returns and resets to complete a working cycle.

Compared with the prior art, the multi-station ejection upper ejection device has the advantages that hydraulic ejection is adopted, ejection force is large, action response is fast, operation is stable, and production efficiency is high.

According to the multi-station ejection upper ejection device, the ejection rod extends out of the upper die cavity only during ejection and ejects the die forging, so that friction with the die forging is avoided, the ejection stability is guaranteed, and the service life is long.

Compared with the traditional mechanical material ejecting mechanism, the multi-station ejecting material ejecting device provided by the invention adopts an integrated structure of the piston and the material ejecting rod, pushes the material ejecting rod to eject materials in the same central axis direction, namely the power direction is consistent with the material ejecting direction, and is short in transmission chain and simple in transmission chain. And the guide sleeve is adopted for guiding, so that the ejector rod runs accurately and the ejection precision is high.

The multi-station ejection upper ejection device adopts a plurality of ejection rods and guide sleeve structures, has good guidance quality and strong anti-unbalance loading capability, and is suitable for multi-station forging occasions.

According to the multi-station ejection upper ejection device, due to the adoption of the multi-ejection rod structure, the ejection force on the forging blank is greatly increased, the relatively large forging blank can be ejected smoothly, the ejection rods can operate accurately, and the ejection precision is high.
