Abstract
The invention relates to a one-time casting forming mold for a prop flange used for a transformer station. The one-time casting forming mold of the prop flange used for the transformer station is characterized by comprising a female die base plate, a female die, a lower punch, a male die, a pressing ring, a pretightening ring, a lower base plate and a lower die holder, wherein the female die base plate is arranged on the lower die holder; stepped through holes are formed in the center of the female die base plate; the female die is arranged on the upper surface of the female die base plate; a spigot structure for preventing misplacement is arranged between the female die base plate and the female die; a cavity is formed in the center of the female die; and the lower punch is formed by connecting the lower end of a mold column with a base of a circular disk. The female die, the male die and the lower punch as well as cushion rings are matched so that the prop flange used for the transformer station is cast and formed for one time. The manufactured prop flange used for the transformer station has high compactness and a good mechanical performance, and the safe coefficient is greatly increased. The pretightening ring in interference fit with the female die is sleeved outside the female die so that the female die can be prevented from being propped up and damaged when being extruded by materials; and through the application of the forming mold with the structure, the casting forming of the prop flange used for the transformer station can be finished for one time, and the mold is hard to damage.
Description
Technical field
The present invention relates to a kind of transformer station pillar flange molding mold, particularly a kind of transformer station pillar flange forging molding mould.
Background technology
Transformer station with pillar flange as shown in Figure 1, mainly comprise ring flange a, cannula portion b and reinforcement c, the center of ring flange a arranges the cannula portion b of interior pore area gradient, between cannula portion b and ring flange a, arrange four reinforcement c, current production transformer station pillar flange adopts the method for casting, and it exists shortcoming and is: interior tissue is loosened, there is the defect such as shrinkage cavity, crackle, can't meet the quality requirement, there is larger potential safety hazard, and scrap more.
The method of forging can also be adopted, during forging, by great tonnage hydraulic machine by blank punch forming, its existing problems are: due in the process material at supporting base center being stamped into top formation monaural, mould can receive extruding and expansive force greatly, very easily damages, even if the size strengthening mould also cannot be avoided, production cost is remained high, does not possess the market competitiveness.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of working (machining) efficiency is high, cost is low and transformer station's pillar flange forging molding mould that product quality is high.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of transformer station pillar flange forging molding mould, and its innovative point is: comprise die backing plate, die, low punch, punch, trim ring, pre-collar, lower bolster and die shoe; Die backing plate, die backing plate is placed on die shoe, and the center of die backing plate has stepped throughhole, and this stepped throughhole is overlapped by upper hole and lower opening and forms, and the diameter in upper hole is greater than the diameter of lower opening; Die, die is placed in the upper surface of die backing plate, arranges the fixing structure preventing from misplacing between die backing plate and die; The center of die has cavity, the side wall profile profiling of pillar flange of the upper portion side wall shape of cavity and transformer station; Low punch, low punch is made up of type post lower end clutch disk base, and disc base just can embed in the upper hole of die backing plate, the casing tube internal hole profiling of pillar flange of type post and transformer station.Packing ring, is sleeved on the type post of low punch, and lower end props up the disc base upper surface of low punch; Punch, is arranged on directly over die, is arranged on upper bolster, form after punch and die, packing ring, low punch matched moulds one with the die cavity of transformer station's pillar flange profiling; Pre-collar, pretension snare is contained in outside die, and with die interference fit, be provided with trim ring outside pre-collar, trim ring is connected and fixed by screw rod and die shoe.
Also comprise moon block teeth and lower push rod, the moon block teeth have a pair, its cross section is arc, the moon block teeth be built in the stepped throughhole of die backing plate, its extrados is close to the inwall of aperture in stepped throughhole, the moon upper end of block teeth prop up packing ring through the chassis of low punch; Lower push rod is arranged in die shoe, drives vertical lift by demoulding oil jar; The top external diameter of lower push rod is slightly less than the lower opening internal diameter of die backing plate, and the top of lower push rod props up the lower end of moon block teeth.
The invention has the advantages that: utilize die, punch and low punch and packing ring to coordinate, one time forging molding goes out transformer station's pillar flange, and obtained transformer station is high by pillar flange compactness, and good mechanical property, substantially increases safety coefficient.Because die overcoat has the pre-collar with die interference fit, die effectively can being avoided to crack damage when being subject to material extruding, adopting the mould of this structure, one-shot forming can complete the forging molding of transformer station's pillar flange, and mould be not fragile.
During the demoulding, the bimester of utilizing lower push rod to promote, block teeth are through low punch, and making packing ring rising eject transformer station also can pillar flange.
Accompanying drawing explanation
Fig. 1 is transformer station's pillar flange structural representation.
Fig. 2 is transformer station's pillar flange forging molding mould structure schematic diagram in the present invention.
Detailed description of the invention
As shown in Figure 2, die backing plate 1, die shoe 2, die 3, low punch 4, packing ring 5, punch 6, upper bolster 7, pre-collar 8, trim ring 9, swing link 10 and lower push rod 11 is comprised.
Die backing plate 1, die backing plate 1 is placed on die shoe 2, and the center of die backing plate 1 has stepped throughhole, and this stepped throughhole is overlapped by upper hole and lower opening and forms, and the diameter in upper hole is greater than the diameter of lower opening.
Die 3, die 3 is placed in the upper surface of die backing plate 1, arranges the fixing structure preventing from misplacing between die backing plate 1 and die 3; The center of die 3 has cavity, the side wall profile profiling of pillar flange of the upper portion side wall shape of cavity and transformer station.
Low punch 4, low punch 4 is made up of type post lower end clutch disk base, and disc base just can embed in the upper hole of die backing plate 1, the casing tube internal hole profiling of pillar flange of type post and transformer station.Packing ring 5, is sleeved on the type post of low punch 4, and lower end props up the disc base upper surface of low punch.
