Abstract
The present invention relates to a forging preparation method of thick-wall thin-bottom basin-like component, and is aimed at salving the problem of that existent forging equipment can not manufacture large-diameter basin-like component. Said forging preparation method includes the following steps: (1), blanking raw material into circular disk blank; (2), placing the circular disk blank into a heating furnace, heating temperature is 1180deg.C-1250deg.C; (3), placing the heated circular disk blank into a mould, forging and forming by utilizing a rotary forging machine; (4), placing the formed component into a normalizing furnace and making soakage and normalizing, normalizing temperature is 890deg.C-950deg.C; and (5), machining the formed component to required component size.
Description
Technical field:
The present invention is relevant with forging and molding method, and is especially relevant with the preparation for processing of big shape dishware part.
Background technology:
The external diameter of basin is greater than 600mm at the bottom of the bridge pad, and existing forging equipment is difficult to forge forges base, processes basin at the bottom of the bridge pad if large-scale forging equipment is made in investment, and then investment is very big, the production cost height.As preparing through machining with strand, then stock utilization is low, and the product bad mechanical property can not satisfy the specification requirement of the bridge pad of railway, highway.
Summary of the invention:
The purpose of this invention is to provide a kind of reduced investment, low cost of manufacture, production efficiency height, good product quality, the spreading preparation method of dishware part at the bottom of the high thick-walled and thin of stock utilization.
The present invention is achieved in that
The spreading preparation method of dishware part comprises the steps: at the bottom of the thick-walled and thin of the present invention
(1) the raw material blanking is become discoid blank,
(2) discoid blank being put into the heating furnace heating-up temperature is 1180 ℃-1250 ℃,
(3) the discoid blank after will heating is put into mould, roll milling forming on the swing type rivet bucker,
(4) with drip molding normalizing after the soaking in normalizing furnace, temperature is 890 ℃-950 ℃,
(5) drip molding that is up to the standards is machined into part.
Mould is made up of patrix 10 and counterdie, patrix 10 is connected to form by concentric large and small cylinder, on the die holder 4 of counterdie bosh 11 is arranged, the big disk of the internal diameter of die cavity 7 and patrix 10 movingly, the internal diameter of the external diameter of die cavity 7 and die holder 4 movingly, having heaters 5 between die cavity 7 and the die holder 4, die-cushion 6 are positioned on the base plate of die holder 4, some push rods 1 are positioned at the through hole of base plate, and the sidewall thickness of end basin blank is more than 2 times of bottom wall thickness in the die cavity.
Raw material in the step (1) is a bar, be heated to 1200 ℃-1250 ℃ after its blanking in heating furnace, with forging hammer it is swaged into discoid blank.
Raw material in the step (1) is a plate, is cut to discoid blank.
The upper and lower mould of mould has the metalworking coolant ejiction opening.
The present invention uses the swing type rivet bucker of big pure position to replace traditional forging equipment to make basin at the bottom of the bridge pad first, equipment investment only is 1/4 of conventional forging equipment investment---1/5, the part internal fiber direction of producing is consistent with the part profile, part metallic gold phase constitution is the same with forging, the mechanical performance height, can work continuously, each production beat only needs 3 minutes.The special mould of the present invention is provided with preheating device and water circulation cooling device, make the preceding shape cavity temperature of beginning rotary forging reach 250 ℃～300 ℃, to reduce the thermal stress of mould, mould when work temperature remain on 350 ℃, mould upper and lower has the metalworking coolant ejiction opening, with the cooling that guarantees die cavity and patrix and lubricated, mould is provided with push rod, can reduce the vexed mould time of workpiece, reduce the heat transfer of workpiece to die cavity, said structure can make every die life reach more than ten thousand.
Waste heat after the utilization of rotary forging drip molding is shaped, normalizing after the normalizing furnace heating, the comprehensive mechanical performance of raising workpiece, but and energy savings.
Description of drawings:
Fig. 1 is a die structure dwg of the present invention.
The specific embodiment:
The bar Metal Cutting is become former plate-like blank, blank is heated to 1230 ℃ in heating furnace, the cake of on 5-10 tons of flat-die hammers, upsetting, send into for the second time heating furnace heat to 1200 ℃ while hot, deliver to 12500KN swing type rivet bucker, pendulum roll over to be shaped in mould, deliver to while hot be heated to 900 ℃ in the continous way soaking normalizing furnace after normalizing.Blank after the normalizing is delivered to machining processes processing parts size after the assay was approved.
The die holder 4 of mould is positioned on the backing plate 2, recirculated cooling water groove 11 is arranged on the die holder 4, by the fastening bolt sealing, have through hole to cooperate on the base plate of die holder 4 with push rod 1 by pressing plate 3, die-cushion 6 in push rod 1 and the die cavity 7 contact, is basin blank 9 at the bottom of the bridge pad of processing on the die-cushion 6.Having heaters 5 between die cavity 7 sidewalls and the die holder 4, die cavity 7 is connected by pressing plate 8 usefulness bolts with die holder 4, and patrix 10 and die cavity 7 have the metalworking coolant ejiction opening.Earlier die cavity is preheating to 250 ℃-300 ℃ during use.Hydrologic cycle cooling system makes mold temperature keep 350 ℃, and the cooling fluid ejiction opening is the metalworking coolant of base to the mould graphite spraying, the cooling of assurance mould and lubricated.
