Abstract
Description
Technical field
The invention belongs to hot precision forming device in machine industry, the specifically a kind of pair I-shaped stainless steel valve of flange The multidirectional precision forming device of body.
Background technology
During double I-shaped stainless steel bodies of flange are extensively using oil, gas extraction, refinement and pipe-line transportation system, Because it works long hours in adverse circumstances, high temperature, high pressure, corrosive medium etc., this performance to valve body are proposed more Requirement high, to ensure the reliability and security during valve use.
Shaped using casting method more than foreign countries' the type stainless steel body at present, the blank of casting method production, casting is very The casting flaw such as easily there is loose, shrinkage cavity, be mingled with so that the mechanical property of its product is far below forging.Except casting method Outside, domestic some producers produce valve body blank using cold-drawing process, using the valve body blank any surface finish of the technique productions Degree is higher, without secondary operation, but complex manufacturing, expects that valve body blank needs 8-9 passage cold drawings, per pass from former material Operation will carry out phosphorus saponification process, solution treatment and more mold exchange, and this results in its low production efficiency, high cost.Except this it Outward, every time blank also needs to carry out pickling processes, and this will necessarily cause larger environmental pollution.
The content of the invention
The present invention is just being directed to the weak point in the presence of above-mentioned prior art and to provide a kind of pair of flange I-shaped not The rust multidirectional precision forming device of steel valve body.The device can realize the I-shaped stainless steel body forging of single pass hot forging forming, profit Shaping double I-shaped stainless steel bodies of flange with the present apparatus has the advantages that energy-saving material-saving, high efficiency, environmental protection.
Building mortion of the invention is from horizontal X direction, vertical Y-direction extrusion billet into shape Forging, installed in four directions On shaping press.Concrete technical scheme is as follows：
The of the invention pair of multidirectional precision forming device of the I-shaped stainless steel body of flange includes left extrusion die component, right extrusion die Tool component, upper extrusion die component, the lower part of extrusion die component four；Left extrusion die component includes left drift extension bar, Zuo Chong Head；Right extrusion die component includes right drift extension bar, right drift；Upper extrusion die component is from top to bottom sequentially connected by including Upper padding plate, ram block, the upper punch for connecing；Lower extrusion die component includes being sequentially connected from the bottom to top die holder, the lower mould for connecing, with And it is installed on ejector beam extension bar, ejector beam in die holder and lower mould central through hole successively from the bottom to top；Wherein, left and right extrusion die Tool component is installed on the horizontal direction of four direction shaping presses, and left drift extension bar is connected with the left oil cylinder of press, right drift extension bar and The right oil cylinder connection of press；Upper and lower extrusion die component is installed on the vertical direction of four direction shaping presses, and upper padding plate is connected to pressure Machine top shoe, die holder is installed on press level table, and ejector beam extension bar is installed on press liftout tank, and push rod is installed on liftout On bar extension bar.
Heretofore described ram block is connected by the dovetail groove on upper padding plate with upper padding plate, ram block and upper padding plate Finger setting is positioned by the ram block being installed in the vertically oriented hole processed on ram block and upper padding plate；The left punching Linked together by dovetail groove between head and left drift extension bar, right drift and right drift extension bar, and in left drift and Zuo Chong Head extension bar, right drift and right drift extension bar connection end are separately installed with for limiting left drift and right drift vertical direction moves Left punch press platen, right punch press platen；The upper punch is connected with ram block by dovetail groove, upper punch front and back position difference It is fixed on ram block by fixed block and screw after fixed block, upper punch before the upper punch of L-shaped structure.Upper punch is direct High temperature blank is acted on, it is higher to material requirements, upper punch and ram block are designed as split mechanism and are effectively reduced mould Cost.
Heretofore described lower mould is installed in the groove of die holder, is anchored on die holder by screw, in die holder groove, Front pods, rear cushion block are provided with the front and rear shoulder of lower mould, the front pods, rear cushion block are combined by dovetail groove with die holder, And be provided with for limiting foremast block pressur plate, rear cushion block that front pods, rear cushion block vertical direction are moved by screw on die holder Pressing plate.
Forming technology principle of the invention is as follows：
By the right drift on the left drift that controls the left and right oil cylinder of press to be installed on left drift extension bar, right drift extension bar it Between distance be adjusted to heating after blank length, blank after heating is positioned on lower mould, press top shoe is moved downward, band The dynamic upper padding plate being installed on press top shoe, ram block, upper punch are moved downward, and are extruded after upper punch contacting metal blank Blank, stops after being expressed to forging desired size, then left drift and right drift is extruded metal base by controlling left and right oil cylinder Material, stops after being expressed to forging desired size, and control press top shoe, left and right oil cylinder move back upper punch, left drift, right drift Afterwards, press liftout tank is moved upwards, ejector beam extension bar is acted on ejector beam ejection forging, is placed into blank and is repeated dynamic above Make.
Beneficial effects of the present invention are as follows：
The of the invention pair of flange multidirectional precision forming device of I-shaped stainless steel body can realize forging needed for single pass shaping, its Forming effect is good, efficiency high, and each part of building mortion is installed and changes simple, and mold materials cost, low processing cost, device are simultaneous Capacitive is strong, by changing the formable other shapes complex forging of mold shape.
