Abstract

The utility model relates to a machinery forges technical field, concretely relates to forge closed mould of flange, the closed mould includes mould and lower mould, and upward the mould encloses to establish with the lower mould and forms into the die cavity, becomes the shape of die cavity and the shape of flange and suits. Use the utility model discloses a manufacturing cost has been saved to the utilization ratio problem of the flange product quality and raw and other materials that the very big promotion of flange technology has been made in the closed die forging, makes the product have more competitiveness.

Description

The closed mould of forged flange
Technical field
The utility model is related to mechanical technical field of forging and in particular to a kind of closed mould of forged flange.
Background technology
How automobile intake and exhaust flange, as the representative of shaped piece product, is realized by this mode of cold punching.Because Automobile intake and exhaust flange shape is irregular, and mesopore is big, and waste material wastes seriously, and stock utilization is low, leads to cold drawing production cost one Directly it can be in any more, and the product plane of disruption is irregular, unsightly, lack industry competition.
It is imperative that the product in a lot of fields is realized using this mode of forging, and in industry, more than 80% product can be with holding Realizing, open die is that raw material are put into die cavity to this mode of formula mould, extrudes slitter edge, is then sliced out slitter edge, obtains wanting Shape, such stock utilization raising is inconspicuous, and product edge density is unstable, and working environment is very poor, is not perfect forging Make the mode of production.
Utility model content
The purpose of this utility model is to provide a kind of closed mould of forged flange, and the processing technology using closed mould is great Improve flange product quality and the utilization rate problem of raw material, save production cost, make product have more competitiveness.
For achieving the above object, the utility model be employed technical scheme comprise that:Described closed mould includes upper die and lower die, Upper mould and lower mould enclose and set formation forming cavity, and the shape of forming cavity is adapted with the shape of flange.
Preferably, described flange includes body, and body is provided with mesopore, mesopore be respectively arranged at the two ends with an installing hole.
Preferably, the length of described installing hole and the aperture ratio of installing hole are 1.3-1.5:1.
Preferably, the operating pressure of described closed mould forged flange is 750-850T.
After technique scheme, the utility model has the positive effect that:
(1) preparation technology of the closed mould forging automobile intake and exhaust flange in the utility model solves automobile intake and exhaust method Easily occur in blue forging slitter edge, lack material, cracking, intensity unstable the problems such as, the forging method of traditional open die, to finished product The ambient intensity of flange periphery slitter edge, cracking and flange has a significant impact, and easily produces cracking phenomena;The utility model is using circle The process by closed mould for the rod material, directly in forming cavity, punching press is obtained, for the forging of the especially thick flange of flange Make, be greatly improved product quality and the utilization rate problem of raw material, make the utilization rate of material reach more than 80%, improve Product quality, has beautified product appearance, saves production cost, makes product have more competitiveness;
(2) in the utility model, closed mould is forged compared with open-die forging flange, few operation excising slitter edge together, from And so that operating efficiency is greatly improved, class's yield is up to 5500, and open-die forging automobile intake and exhaust flange at most can only achieve 3000, class's yield improves 83.3%, improves operating efficiency.
Brief description
Fig. 1 is the structure chart of the automobile intake and exhaust flange in the utility model;
Fig. 2 is the structure chart of the closed mould of forged flange in the utility model.
Wherein:1st, body, 2, mesopore, 3, installing hole, 4, upper mould, 5, lower mould, 6, forming cavity.
Specific embodiment
With reference to the accompanying drawings and detailed description the utility model is described in further detail.
In the utility model, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection ", " Gu Fixed " etc. term should broadly understood, for example, it may be being fixedly connected or being detachably connected or integral;Can be It is mechanically connected or electrically connect;Can be to be joined directly together it is also possible to be indirectly connected to by intermediary, can be two The connection of element internal or the interaction relationship of two elements.For the ordinary skill in the art, can basis Concrete condition understands concrete meaning in the utility model for the above-mentioned term.
Embodiment 1
As shown in figure 1, being automobile intake and exhaust flange of the present utility model, described flange includes body 1, and body 1 is provided with Mesopore 2, mesopore 2 be respectively arranged at the two ends with an installing hole 3.The length of installing hole 3 is 1.3-1.5 with the aperture ratio of installing hole 3:1, Be this flange be thick flange.
As shown in Fig. 2 being closed mould of the present utility model, described closed mould includes mould 4 and lower mould 5, upper mould 4 and lower mould 5 enclose and set formation forming cavity 6, and the shape of the shape of forming cavity 6 and described flange is adapted.
A kind of closed mould production technology of automobile intake and exhaust flange, comprises the following steps:
(a) blanking:With blank cutter or band mill, rod raw material are sawn into the standby blank of technological requirement size;
