Description
Technical field
The invention belongs to forging equipment component, particularly relate to the ejecting device of a kind of oil hydraulic press forging and stamping blank.
Background technique
After wheel Pressesforging forging and stamping steel billet, need to use knockout to be separated steel billet and mould.Current use knockout, cylinder body is the moved cross beam of oil hydraulic press, oil inlet and outlet is all located in moved cross beam, plunger front end flange is connected with moved cross beam by the screw of 12 M64, and backing plate is installed in the outside of plunger flange, and punch pad is connected with moved cross beam by the screw of 20 M48, the plunger of stripping tank passes the endoporus of punch pad, the ouput force of plunger acts on demoulding push rod, and power is delivered to the upper kink in punch set by demoulding push rod again, realizes the demoulding.The defect existed is, this knockout complex structure, great inconvenience is brought to maintenance, when needs change stripping tank sealing or plunger, first the punch pad of 17 tons of weighing must be removed, and then the cylinder flange assembled with moved cross beam is removed, final could replacing seals or plunger, cause whole maintenance process for up to more than 16 hours, inefficiency, impact is normally produced; Maintenance process is entirely by manual operation, and labor intensity is large, there is potential safety hazard.
Summary of the invention
In order to overcome the defect that prior art exists, the object of this invention is to provide a kind of wheel oil hydraulic press stripping tank, shortening engineering time, increasing work efficiency, reduce labor intensity, eliminate safe hidden trouble.
Wheel oil hydraulic press stripping tank, comprises moved cross beam and punch pad, and groove is established in the moved cross beam lower end being characterized in described, and groove vicinity establishes tapped hole, and moved cross beam establishes oilhole, docks with the oilhole of stripping tank; Described punch pad establishes step hole, and the groove center line of step hole and moved cross beam, with point-blank, all establishes through hole and tapped hole around step hole, and the corresponding threaded holes on through hole and moved cross beam closes, and is fixed on moved cross beam by bolt by punch pad; Stripping tank is placed in step hole, and upper end withstands in the groove of moved cross beam, and be bolted on punch pad, plunger is loaded in cylinder body.
The present invention improves further, and described stripping tank is made up of cylinder body and plunger, and cylinder body upper end establishes oilhole to be connected with oilhole set by moved cross beam, and pressure oil enters stripping tank inner chamber; Plunger is at least established 2 grooves, guidance tape is placed in groove, guidance tape and inboard wall of cylinder block Spielpassung; Establish pressure oil through hole in plunger, link up rod chamber and rodless cavity, keep upper and lower cavity pressure balance; Internal thread is established in cylinder body lower end, and gland is threaded with cylinder body, and plunger is longitudinally fixing by gland, ensures that plunger moves up and down in cylinder body.
The present invention improves further, and described cylinder body establishes convex shoulder, and cylinder body is placed in the step hole of punch pad, and convex shoulder establishes through hole, corresponding with tapped hole set on step hole, is bolted on punch pad.
The present invention improves further, and described gland establishes outside thread, matches with the internal thread of cylinder body, and gland spinning is on cylinder body; Establish static seal and inboard wall of cylinder block interference fit on outside gland, gland inside upper part establishes guidance tape and plunger Spielpassung, and gland lower inside establishes motive sealing and plunger interference fit.
The present invention improves further, establishes static seal outside described cylinder body and between the groove of moved cross beam, and static seal is distributed in the both sides of cylinder body oilhole and moved cross beam oilhole symmetrically.
During the demoulding, pressure oil enters stripping tank by moved cross beam oilhole, oil hydraulic cylinder oilhole, and stripping tank is under the effect of upper and lower cavity difference in areas, and plunger moves downward, and promotes the action of demoulding push rod, realizes the demoulding; After the demoulding, when suppressing next block steel billet, by demoulding push rod, plunger is promoted upwards action, plunger gets back to top, waits for next stripping action.
Compared with prior art, advantage is novel, and structure letter is gathered, rationally; Stripping tank is independently made, and position is displaced downwardly in punch pad, can under the prerequisite of not removing press machine punch pad, realize integral installation and the dismounting of stripping tank, reduce to 2 hours engineering time, reduce the labor intensity of staff, greatly improve the operating rate of oil hydraulic press, eliminate the potential safety hazard of dismounting, fit on backing plate.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
