Background technology
The mode that tradition is manufactured valve body adopts casting, welding, Die Forging Hammer, hydraulic press no-draft forging etc. more, and these technology all have some limitations and defect.For example: foundry goods mechanical performance is low; The product of Die Forging Hammer technique manufacture is because heart portion is not fully out of shape overall mechanical properties is under some influence, and stock utilization is lower; Vertical hydraulic press forming technology can forge valve body inner bore, but can not be shaped for the triple-valve body with flange simultaneously, and efficiency is not high.Multi-ram forging can improve plasticity and the forging mechanical performance of metal; Complex contour, true-to-size hollow forging can be forged, thereby stock utilization and production efficiency can be significantly improved.In recent years, multi-ram forging has obtained development rapidly, and large-scale triple-valve body increases year by year in the demand of the industries such as nuclear power, oil, chemical industry.Multiway forging technique multi-ram forging die tool used has multiple die joints, and each die joint must be closed reliably in the time forging, otherwise there will be forge scrap, or even equipment and industrial accident.The large valve body required load that is shaped is large, and adopts the clamping system of common press, and mold clamping force is generally the more than 2 times of workpiece load.In addition, the selection of mold clamping force is also most important, and choosing mold clamping force need to increase equipment tonnage when excessive, thereby causes bad economic consequences; And in the time that mold clamping force is less than required numerical value, in die forging process, will produce die sinking phenomenon, thus cause forging to produce overlap, affect forging forming and reduce forging quality.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of clamping apparatus for multi-ram forging hydraulic press, and this mechanism can make die joint reliably closing in forging process.
The technical scheme that the utility model adopts is: the clamping apparatus of multi-ram forging hydraulic press comprises can be mutually closed Upper Die-sleeve and lower die-sleeve, two locked mode circles and Level Promoting bar, it is characterized in that: Upper Die-sleeve and lower die-sleeve have respectively protuberance, Level Promoting bar is connected with locked mode circle and promotes locked mode circle and engages with the protuberance of described Upper Die-sleeve and lower die-sleeve.
Preferably, described protuberance and described locked mode circle madial wall are the wedge type cooperatively interacting.
Preferably, utilize hydraulic cylinder to act on described Level Promoting bar and promote locked mode circle.
Preferably, this clamping apparatus can be used for horizontal parting, can be used for again vertical parting.
A locked mode method for multi-ram forging hydraulic press, Level Promoting bar promotes locked mode circle and engages with the protuberance having respectively on Upper Die-sleeve and lower die-sleeve, so that Upper Die-sleeve and lower die-sleeve are fixed.
By above-mentioned multi-ram forging hydraulic press clamping apparatus be applied to the method for triple-valve body structure multiway forging, it comprises the steps:
(1) to promote patrix 9 descending for vertical catch bar 7, realizes patrix 9 and counterdie 11 matched moulds, the blank after heating, scale removal and base inserted in the mold cavity of multi-cored forging press;
(2) hydraulic cylinder of the left and right sides acts on Level Promoting bar 10 locked mode circle 4 is pushed to Upper Die-sleeve 5 with the interconnective two ends of lower die-sleeve 2 and is fixed;
(3) vertical core pin 8 goes downwards to precalculated position, then stops, and the descending compacting of master cylinder pressure head 6 of multi-cored forging press is to setting stroke, after completing in packing state;
(4) horizontal core pin 3 inwardly extruding simultaneously, completes left and right side position endoporus and Flange Forming;
(5) horizontal core pin 3 resets, and locked mode circle 4 resets, and vertical core pin 7 resets, master cylinder backhaul;
(6) upper and lower die sinking, ejector beam 1 ejects workpiece.
Compared with prior art, the beneficial effects of the utility model are: can realize die joint reliably closing in the time forging by described clamping apparatus, press need not be considered mold clamping force at work, greatly reduce energy consumption, after completing, forging facilitates die sinking, and described clamping apparatus is simple in structure, be easy to realize low cost of manufacture.
