Abstract

The utility model discloses a combined type flange forming forging die. The combined type flange forming forging die consists of an upper die and a lower die; an axial through hole for assembling an upper mandrel is formed in the center of an upper die seat of the upper die; another axial through hole for assembling a lower mandrel is formed in the center of a lower die seat of the lower die; an inwards concave upper die cavity is formed in the bottom end surface of the upper die seat; the downward shaft end of the upper mandrel passes through the upper die cavity to expose from the bottom end surface of the upper die seat; an inwards concave lower die cavity is formed in the upward end surface of the lower die seat; the upward end surface of the lower mandrel is positioned in the lower die cavity; the upper mandrel is coaxially opposite to the lower mandrel, and the space between the upper mandrel and the lower mandrel is shown as H1=3-5mm; the space H2 between the end surfaces of the upper die seat and the lower die seat is 1 to 2mm less than that between the end surfaces of the upper mandrel and the lower mandrel. According to the combined type flange forming forging device, the die cavities and the mandrels are combined, which is beneficial to smooth die releasing of a forging stock, and thus the production efficiency is raised.

Description

Modular flange becomes swage die
Technical field
The utility model relates to a kind of semi-open type forging die, and specifically, the utility model relates to a kind of modular flange and becomes swage die.
Background technology
Suitability for industrialized production steel flange mainly contains two kinds of forming methods, and a kind of is open die forging, and another kind is die forging.Traditional free forging process condition is easy, is convenient to tissue and produces.Shortcoming is the real core moulding of forging stock, and allowance is large, causes stock utilization low, and production efficiency is poor.The forging shape standard of die-forging forming, reserved chipping allowance is few, and stock utilization is high, and this kind of one-tenth swage die is widely used in batch production.Because of flange regular shape, the flange forming forging die that the industry is used is divided into upper die and lower die two parts, and upper and lower mould structure is identical, is all die cavity and core rod integral structure.This kind of integrally-built forging die is simple in structure, easily manufactures, and forges processing ease, and its deficiency is that the forging stock demoulding is not smooth, has directly reduced production efficiency.
Utility model content
The utility model is mainly for the not smooth problem of the forging stock demoulding of prior art, propose a kind of simple in structure, moulding is accurate, the demoulding is easy to modular flange and becomes swage die.
The utility model is achieved through the following technical solutions technical goal.
Modular flange becomes swage die, and it consists of jointly upper die and lower die.The upper bolster of described patrix is provided with the equipped upper mandrel of axially extending bore between two parties.The die shoe of described counterdie is provided with the equipped lower mandrel of axially extending bore between two parties.Its improvements are: described upper bolster bottom face is provided with the upper cavity of indent, and upper mandrel axle head down exposes from upper bolster bottom face through upper cavity.Described die shoe end face is upward provided with the lower mode cavity of indent, and lower mandrel is towards upper end surface among lower mode cavity, and upper mandrel is coaxially relative with lower mandrel, alternate H between both end faces 1=3~5mm, phase spacing H between upper bolster and die shoe end face 2than the little 1~2mm of phase spacing between upper mandrel and lower end face of mandrel.
In said structure, the axis of cone section that described upper mandrel is 1:20~1:50 towards lower shaft end, and make circular arc chamfering.
The utility model compared with prior art, has following good effect:
1, die holder join core shaft structure simple, make easily;
2, the built-in mandrel of die cavity forms the endoporus of forging, and this structure, when saving material, is also saved follow-up amount of machining greatly;
3, upper and lower mandrel coordinates with die holder for bascule, and the upper mandrel end of adding configuration is taper shaft, makes the forging stock demoulding easy.
Accompanying drawing explanation
Fig. 1 is the utility model structural profile schematic diagram.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Modular flange shown in Fig. 1 becomes swage die, and it consists of jointly upper die and lower die, and patrix is arranged on press ram servo-actuated, and counterdie is arranged on press bench.The upper bolster 1 of described patrix is provided with the equipped upper mandrel 2 of axially extending bore between two parties, and the die shoe 4 of counterdie is also provided with the equipped lower mandrel 5 of axially extending bore between two parties.Upper bolster 1 bottom face is provided with the upper cavity 3 of indent, and upper mandrel 2 axle head down exposes from upper bolster 1 bottom face through upper cavity 3.Die shoe 4 end face is upward provided with the lower mode cavity 6 of indent, and lower mandrel 5 is arranged in die shoe 4 and runs through lower mode cavity 6, and lower mandrel 5 end face is upward lower than die shoe 4 end face upward.Upper mandrel 2 is coaxial relative with lower mandrel 5, the alternate H of both end faces 1=3~5mm, phase spacing H between upper bolster 1 and die shoe 4 end faces 2than the little 1~2mm of phase spacing between upper mandrel 2 and lower mandrel 5 end faces.The present embodiment is the flange forming forging die of Φ 200mm * 18mm, and little because of specification, shape standard, forges and presses surplus little, therefore alternate 3mm between upper mandrel 2 and lower mandrel 5 opposing end surfaces, between upper bolster 1 and die shoe 4 end faces, distance is 2mm.This kind of forging die is semi-open type, and during forging and stamping, swollen mould metal charge overflows formation overlap from gap, so greatly reduces the impact of forging force to die cavity, and die life is improved a lot.Because die cavity and mandrel are combining structure, be conducive to the smooth demoulding of forging stock on the other hand, can save unproductive time thus, enhance productivity.
