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
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.
