Embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples：

Band handle flanged ball valve valve body forging with reference to shown in Fig. 1, Fig. 2, mainly by left flange a, right flange b, osculant Chamber c and handle flange d compositions.Intermediate cavity c abuts left flange a, and handle flange d is located at intermediate cavity c surface, the forging Intermediate cavity need completed in forging and molding.

Firstly the need of making base mould and finisher.

As shown in Figure 3, Figure 4, base mould is mainly made up of base upper male mould 1, base lower cavity die 2, ejector beam 3 and backing plate 4.

Base upper male mould 1 includes mounting of roof plate plate 1a, intermediolateral column and conical lower portion 1c compositions, three in one shaping, top plate Installing plate 1a is used to be connected with power section, and power section drives base upper male mould 1 to move up and down.Intermediolateral column include cylinder 1b and In the pillar 1d that cylinder 1b outer walls extend laterally, and cylinder 1b flushes with pillar 1d bottom surface.Cylinder 1b and pillar 1d bottom surface Matched with the upper surface of preformed workpiece, preformed workpiece carries the blank of handle flange.Conical lower portion 1c is used for preform work The intermediate cavity of part.

The inner chamber of base lower cavity die 2 is divided into die cavity top 2a and die cavity bottom 2b, die cavity top 2a sections and intermediolateral column Bottom surface is matched, and the workpiece of handle flange blank is carried for preform.Die cavity top 2a height is more than conical lower portion 1c height Degree, die cavity bottom 2b is cylindrical hole, and cylinder 1b, conical lower portion 1c, cylindrical hole are coaxially disposed, cylinder 1b, cylindrical hole, conical bottom Portion 1c, pillar 1d cross-sectional area successively decrease successively.Backing plate 4 is located at the intracavity bottom of base lower cavity die 2, and ejector beam 3 is from bottom to top It is against through lower cavity die 2 on backing plate 4, base upper male mould 1 moves towards base lower cavity die 2, until under the bottom surface and base of intermediolateral column The inner chamber top surface of cavity plate 2, which flushes, realizes matched moulds, and after component shaping, base upper male mould 1 moves upwards, and ejector beam 3 promotes backing plate 4 simultaneously Drive workpiece to move upwards, realize the demoulding.

As shown in Fig. 5-Fig. 7, finisher is mainly by finish-forging upper male mould 5, finish-forging lower punch 6, die holder 7, left half module 8 and the right side Half module 9, finisher is integrally symmetrical.Finish-forging lower punch 6 is in shaft-like, stretches into left half module 8 and right half through die holder 7 from bottom to top In the cavity that mould 9 surrounds.After left half module 8 closes up with the right move toward one another of half module 9, while finish-forging upper male mould 5 moves downward, finish-forging Lower punch 6 moves upwards, final forming belt handle flanged ball valve valve body forging.

Left flange a is shaped by finish-forging upper male mould 5, left half module 8 and right half module 9, and right flange b, handle flange d are by left half module 8 Shaped with right half module 9, intermediate cavity c is shaped by finish-forging lower punch 6, and after component shaping, finish-forging upper male mould 5, finish-forging lower punch 6 are same When return to initial position after, left half module 8 and right half module 9 return to initial position.

Preferably, the top of die holder 7 of finisher is additionally provided with cushion block 10.

As shown in figure 8, a kind of forging forming method with handle flanged ball valve valve body forging, is comprised the following steps that：

The first step：Make mould, including base mould and finisher.

Second step：Blanking, by blanking dividers lattice.

3rd step：Heating, will be put into heating furnace by bar good under specification, is come out of the stove after being heated to initial forging temperature.

4th step：Base, the bar come out of the stove is put into the base lower cavity die 2 of base mould, base upper male mould 1 is towards under base Cavity plate 2 is moved, until the bottom surface of intermediolateral column flushes with the inner chamber top surface of base lower cavity die 2 and realizes matched moulds, bar is pressed into base After expecting shape, base upper male mould 1 moves upwards, returns to initial position, and ejector beam 3 moves upwards, promotes backing plate 4 and band is started building Part is moved upwards, and workpiece is ejected into lower cavity die, takes out workpiece, completes a working cycles.

5th step：Sub-material, also known as have a waistline, the workpiece of base will be made, be put into axis horizontal in two halves circle clamp, work Part rotate, complete sub-material, i.e., had a waistline in workpiece loins position, make the material of workpiece left-right parts evenly distributed, be easy to finish-forging into Material can be full of whole die cavity during shape.It is the process often having in forging forming to have a waistline, and be will not be repeated here, in conventional belt handle method Also there is the step in the forging and forming technology of blue ball valve body forging.

6th step：Finish-forging shapes, and the workpiece that sub-material is completed is put on the finish-forging lower punch 6 of finisher, stamp forging hydraulic press Left and right die cylinder to intermediary movements, drive left half module 8 to close up with the right move toward one another of half module 9, left half module after closing up, right half Mould is locked.Afterwards, while stamp forging hydraulic press master cylinder drive finish-forging upper male mould 5 moves downward, oil cylinder under stamp forging hydraulic press Drive finish-forging lower punch 6 to move upwards, final forming belt handle flanged ball valve valve body forging, left flange a by finish-forging upper male mould 5, Left half module 8 and right half module 9 are shaped, and right flange b, handle flange d are shaped by left half module 8 and right half module 9, and intermediate cavity c is by finish-forging Lower punch 6 shapes, and after component shaping, first returns to initial position simultaneously by finish-forging upper male mould 5, finish-forging lower punch 6, then by left half Mould 8 and right half module 9 return to initial position, finally take out workpiece, complete a working cycles.
