Description
Technical field
The utility model relates to machining apparatus technical field, is specifically related to a kind of all-welded ball valve valve body shaping jig.
Background technology
The valve body part of traditional cast steel ball valve is bolted by valve body and valve gap and forms, the two ends of valve body mostly are flange arrangement, also with bolts, but after long-term engineering application, find that the phenomenon of leaking often appears in bolt junction, thus affect the safe operation of pipe-line system.People had invented all-welded ball valve afterwards, all-welded ball valve adopts all-welded structure, valve body by girth joint by main valve body and lateral body integrally welded, the inside and outside sealing of valve is greatly improved, valve weight obtains very large reduction, make the installation of valve become more convenient, not only reduce the cost of engineering construction, also save the time.Therefore all-welded ball valve just at fast fetching for traditional cast steel ball valve, market prospects are very good.Valve body adopts steel pipe through mould hydroforming, and because Design of Dies is unreasonable, shaping dies does not have positioning function, homogeneity of product is not strong, and needing operator's righting very dangerous in production process, the not high reason of production efficiency causes the shaping learies of valve body large, and production cost is high.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of all-welded ball valve valve body shaping jig; the utility model efficiently solves existing all-welded ball valve in hydraulic press die molding process; homogeneity of product is poor; and in forming process; need operating personnel to carry out manual righting to product, often valve body can be pressed askew, compressive strain; cause valve body scrappage high potential safety hazard in forming process large, valve stem sleeve postwelding cannot use the problem of unitary mould die mould.
The utility model is achieved through the following technical solutions:
A kind of all-welded ball valve valve body shaping jig, comprise the upper flange (1), the lower flange (2) that are fixedly connected with the upper table of hydraulic press, lower table, upper flange (1), lower flange (2) are provided with installs through hole (3), upper flange (1), lower flange (2) are fixedly connected with upper table, lower table respectively by installing through hole (3), it is characterized in that: described upper flange (1) is fixed with mold (4), lower flange (2) is fixed with bed die (5), and the lower flange (2) of bed die (5) bottom is provided with valve body jack-up core (6).
The further Technological improvement plan of the utility model is:
Described mold (4) free end sidewall is provided with semi-circular through hole A(41), bed die (5) free end sidewall is provided with semi-circular through hole B(51), semi-circular through hole A(41), semi-circular through hole B(51) be combined into valve pocket installing hole (7).
The further Technological improvement plan of the utility model is:
Be provided with valve body jack-up core (6) in the through hole (52) of described bed die (5) installation lower flange (2) side, through hole (52) upper end is provided with retention Hp limit (53) and mates clamping with valve body jack-up core (6) base (61).
The utility model compared with prior art, has following obvious advantage:
1, the utility model arranges Sphere orientation core in bed die, and in hydraulic press operation process, mould accurate positioning makes the homogeneity of product of shaping strong, product quality significantly improves, product does not need human assistance after putting into mould, improves the security of production, enhances productivity.
2, the utility model is provided with valve rod installing hole in junction, top and bottom, before hydraulic press operation, first valve ball, valve rod can be loaded in advance in valve body, not only save operation, but also improve assembly precision.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
As shown in Figure 1, the utility model comprises the upper flange 1, the lower flange 2 that are fixedly connected with the upper table of hydraulic press, lower table, upper flange 1, lower flange 2 are provided with installs through hole 3, upper flange 1, lower flange 2 are fixedly connected with upper table, lower table respectively by installing through hole 3, described upper flange 1 is fixed with mold 4, lower flange 2 is fixed with bed die 5, the lower flange 2 bottom bed die 5 is provided with valve body jack-up core 6.
Described mold 4 free end sidewall is provided with semi-circular through hole A41, and bed die 5 free end sidewall is provided with semi-circular through hole B51, and semi-circular through hole A41, semi-circular through hole B51 are combined into valve pocket installing hole 7.
Be provided with valve body jack-up core 6 in the through hole 51 that described bed die 5 installs lower flange 2 side, through hole 52 upper end is provided with retention Hp limit 53 and mates clamping with valve body jack-up core 6 base 61.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
