Abstract
The utility model relates to a valve body blank formed by stamp forging, which comprises a left connection portion, a right connection portion and a middle connection portion, wherein the left connection portion and the right connection portion are connected, two ends of the left connection portion and the right connection portion are respectively provided with a convex rib extending outwards along the outer periphery, and the top end of the middle connection portion is provided with a convex rib extending outwards along the outer periphery. By arranging the convex ribs at different positions of the valve body blank, the valve body blank is easy to produce. Furthermore, a die for producing the valve body blank is long in service life and not easy to crack so that production cost is saved, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of valve body blank, the valve body blank that particularly a kind of die forging of oil well head high pressure valve forms.
Background technique
Produce at present the manufacturing enterprise of oil well head high pressure valve, adopt open die forging production mostly, such result is that the materials consumption of blank is very big, and the following process cycle is long, and it is low to pay punctual rate, and cost of production is bigger.High pressure valve chaeta base preferably adopts the die forging manufacturing, but in actual production process, because forging is the heavy forging of dark die cavity; As shown in Figure 1, all there are insufficient phenomenon in various degree in the two ends of left and right sides joint 1,3, the top of center joint 2; And since this to locate local fillet size less; Mould exists bigger stress to concentrate at this position, very easily ftractures, for production is made troubles.
The model utility content
The utility model problem to be solved provides the valve body blank that a kind of die forging that is easy to produce forms, and overcomes the problems referred to above that exist in the existing technology.
The valve body blank that a kind of die forging of the utility model forms; Comprise continuous left and right sides joint and center joint; In the said left and right sides two ends of joint respectively be provided with outward extending convex tendon along the outer periphery, and the top of joint also is provided with the outward extending convex tendon along the outer periphery at the center.
The said convex tendon of the utility model is formed by the respective groove in the mould in the die forging.
Through above technological scheme, the valve body blank that the utility model die forging forms is provided with convex tendon through the diverse location at the valve body blank; Make the valve body blank itself be easy to produce, and it is long to produce die life of this valve body blank, is difficult for breaking; Save cost of production, improved manufacturing efficiency.
Description of drawings
Fig. 1 is the structural drawing of known valve body blank.
Fig. 2 is the structural drawing of the utility model valve body blank.
Embodiment
As shown in Figure 2; The valve body blank that a kind of die forging of the utility model forms; Comprise continuous left and right sides joint 1,3 and center joint 2; In the left and right sides two ends of joint respectively be provided with outward extending convex tendon 4,5 along the outer periphery, and the top of joint 2 also is provided with the outward extending convex tendon 6 along the outer periphery at the center.Through the setting of convex tendon, make this valve body blank be easy to manufacture.
Above-mentioned convex tendon 4,5,6 is formed by the respective groove in the mould in the die forging.For making the valve body blank of the utility model; The place that the inherent corresponding difficulty of employed stamp forging mould is full of is provided with groove; Form the convex tendon on the valve body blank through this groove; Groove is set following several beneficial effects can be arranged: (1) can be contained in the forging process because scale, and graphite is piled up the rubbish that produces, and avoids owing to the operator removes untimely being full of of forging that influence; (2) groove can have the effect of the air storage instructed, and is equivalent to the effect in air storage hole in the mould, avoids damaging owing to there be being full of of excessive effects of air pressure forging in this place and cause that mold stresses is excessive; (3) because the fillet of anti-groove generally than the big one magnitude of forging fillet of normal design, can avoid making owing to fillet is too small mould to produce stress at this place concentrates but ftracture, thus the working life of raising mould.
Claims (2)
1. valve body blank that die forging forms; Comprise continuous left and right sides joint (1,3) and center joint (2); It is characterized in that; The two ends of the joint in the said left and right sides (1,3) respectively be provided with along the outer periphery outward extending convex tendon (4,5), and the top of joint (2) also is provided with the outward extending convex tendon (6) along the outer periphery at the center.
2. valve body blank according to claim 1 is characterized in that, said convex tendon (4,5,6) is formed by the respective groove in the mould in the die forging.
