Refer to shown in Fig. 1 and Fig. 2, triple-valve body with large scale ring flange is the version that Cemented filling industry is commonly used, it mainly adopts forging method to produce at present, when adopting the triple-valve body forging of free forging method shaping large scale ring flange, the method through machining is needed to remove the flange plate structure of a large amount of material acquisition valve bodies, not only reduce stock utilization, and goods metal streamline is discontinuous, and then affects the service life of workpiece; When adopting unidirectional die forging method to forge, above-mentioned defect can be improved, but due to its goods side flange dish diameter comparatively large, impression is full of difficulty, easily produces fold defect; Cannot be shaped endoporus, and stock utilization is also lower, and profile can produce larger overlap, need increase trimming operation.
Therefore, need a kind of multidirectional coextrusion method of new large scale ring flange triple-valve body to solve the problem.
Summary of the invention
The object of the invention is the defect for prior art, provide one can effectively improve material Filling quality, reduce the multidirectional coextrusion method of the large scale ring flange triple-valve body of valve body forming defects.
For achieving the above object, the multidirectional composite extrusion die of large scale ring flange triple-valve body of the present invention can adopt following technical scheme:
A kind of multidirectional composite extrusion die of large scale ring flange triple-valve body, comprise upper cavity die, lower cavity die, side flange dish, upper extruding disk, horizontal pecker, middle impression and side flange impression, described upper cavity die is provided with the first impression running through described upper cavity die, the bottom of described lower cavity die is provided with the second impression, the side of the first impression and described upper cavity die described in described second impression UNICOM, described lower cavity die is respectively arranged with three impression corresponding with described first impression and the second impression and the 4th impression, described first impression and the 3rd impression form middle impression, described second impression and the 4th impression form side flange impression, described upper extruding disk is provided with in described middle impression, described side flange dish is provided with in described side flange impression.
Further, described upper extruding disk is provided with pecker.Can endoporus be gone out, improve stock utilization.
Further, described side flange dish is provided with horizontal pecker.Can endoporus be gone out, improve stock utilization.
Beneficial effect: the multidirectional compound extruding die lamps structure of large scale ring flange triple-valve body of the present invention is simple, easy to use, without the need to base, mould impression is divided into middle impression and side flange impression, metal Rational flow in forming process can be controlled, effectively avoid fold defect, improve the quality of products.
The invention also discloses a kind of multidirectional coextrusion method of large scale ring flange triple-valve body, utilize the multidirectional composite extrusion die of the large scale ring flange triple-valve body described in any one of claim 1-3, comprise the following steps:
1), first by mould and die preheating, lower cavity die is fixed on the table, puts into lower cavity die by after blank heating, and upper cavity die and lower cavity die are closed;
2), upper extruding disk and side flange dish are put into middle impression and side flange impression respectively;
3), under the effect of upper extruding disk, blank is made first to be full of described middle impression;
4), side flange dish backs away, and upper extruding disk continues to lower feeding, and under the acting in conjunction of upper extruding disk and side flange dish, blank flows into described side flange impression, until blank is full of described side flange impression, forms ring flange.
Beneficial effect: the multidirectional coextrusion method of large scale ring flange triple-valve body of the present invention utilizes middle impression and side flange impression, can control metal Rational flow in forming process, effectively avoid fold defect; Lower extruding disk first retreats the control method of extruding disk feeding again, effectively can improve ring flange impression metal Filling quality; Adopt control method of the present invention, effectively can improve the forming quality of material.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
Refer to shown in Fig. 3, the multidirectional composite extrusion die of large scale ring flange triple-valve body of the present invention, comprises upper cavity die 1, lower cavity die 2, side flange dish 3, upper extruding disk and upper extruding disk 4; Impression is surrounded middle impression 6 and side flange impression 7 by mold portions.
embodiment 1:
Mould of the present invention is arranged on to have vertically bores a hole on the multidirectional Compound Extrusion forcing press of cylinder and level perforation cylinder, lower cavity die 2 is fixed on the workbench of forcing press, upper cavity die 1 is fixed on moved cross beam, upper extruding disk 4 is arranged on the vertical perforation cylinder plug of forcing press, and side flange dish 3 and lower extruding disk 5 are arranged on the horizontal cylinder of multidirectional Compound Extrusion forcing press and the plunger of level perforation cylinder respectively; Mold portions can realize self-movement under the control of forcing press.
In extrusion process, first extrusion die is preheating to 300 DEG C, then will puts into fixing lower cavity die 2 on the table after suitable dimension pole blank heating 1230 DEG C, upper cavity die 1 is descending to be closed with lower cavity die 2.Now, lower extruding disk 5 is positioned at workpiece neck portion centre position, surrounds middle impression 6 with upper cavity die and lower cavity die acting in conjunction.Upper extruding disk 4 goes downwards to appointment stroke with a suitable speed, makes blank be full of middle impression, as shown in Figure 4.Then extruding disk 5 and side flange dish 3 is descended to retreat, now side flange impression 7 communicates with middle impression 6, and along with upper extruding disk 4 is descending further, metal is extruded to side flange impression 7 from the passage in the middle of two impressions, until upper extruding disk 4 reaches predetermined stroke stop motion, as shown in Figure 5.Side flange dish 3 and horizontal pecker 5 coordinated movement of various economic factors, extrude extruding part blank, make blank be full of impression, shaping ring flange, as shown in Figure 6 subsequently.
In extrusion process, guarantee that ring flange impression is full of, avoid the generation folded, can effectively improve the quality of products.
