Abstract
The invention discloses a flange shaft forging method. The flange shaft forging method includes steps of (1) manufacturing a special composite die composed of an outer die, an inner die, a press block and a drain plate; (2) placing the inner die into the outer die and pressing to form a complete die; (3) placing a heated blank into an inner die cavity; (4) placing the pressing block on the blank and in the die cavity; (5) forging and pressing the press block into the die cavity so as to allow the blank to deform and fill with the die cavity; and (6) lifting the integral die to place on the drain plate, stamping the press block to enable the press block and the inner die to separate from the outer die, separating the press block and the inner die, and taking out the forged blank. Compared the prior art, the flange shaft forging method is easier in demoulding, reverse rotation dies are omitted, demounting way is changed, time and labor are saved, and speed and efficiency are high. The inner die is light in weight and easy to carry and cool. Further, multiple inner dies can be used by turns, the service live of the die is prolonged, and forging cost is reduced. The flange shaft forging method is convenient to operate, low in consumption and applicable to forging and forming of circular and special-shaped flange shafts.
Description
Technical field
The invention belongs to the forging field, specifically a kind of forging method of flange shaft.
Technical background
Flange shaft is automobile, agricultural machinery and the important parts of other plant equipment.Along with the continuous development of China auto manufacturing, agricultural machinery manufacturing industry and other machinery manufacturing industry, increasing to the demand of forging parts, specification requirement is more and more higher.In known technology, the forging method of flange shaft is the method that adopts single mode to forge, process a die cavity that conforms to the geomery of required flange shaft forging at a mould exactly, in forging process, blank after the heating is put into die cavity, make the blank modification be full of die cavity through forging and pressing, mould then overturns, the punching press depanning from mould of flange shaft forging, finish the forging process of a flange shaft.This forging method has some not enough: 1. operator's labour intensity is big, because forging of every satin needs mould of upset, need pay more manual labor, and the time spent is more, inefficiency.2. forging demoulding difficulty is big, and the axial region of general flange shaft is longer, and forging is difficult to hold from the mould the inside punching press required dynamics of coming out, and must use less power to divide punching press depanning several times.3. the mold cools down inconvenience is amassed greatly because one-piece moule is concrete, and heavier, cooling velocity is slow, can not work continuously, if work continuously, the die cavity internal temperature rises, and hardness descends, and cooling die at this moment must stop, otherwise the inner local modification of die cavity gently then needs to repair, and heavy then mould is scrapped.In sum, the big inefficiency of this forging method operator labour intensity, it is very necessary studying a kind of new forging method.
Summary of the invention
Purpose of the present invention is to overcome the deficiencies in the prior art part, and a kind of forging method of improved flange shaft is provided, and the labour intensity that it has reduced the operator has improved efficiency, has reduced the forging cost.
For achieving the above object, the present invention takes following technical scheme: at first prepare the specific complex mould, this composite die includes: external mold, internal mold, briquetting, drain cap, external mold are round busses that tapered endoporus is arranged, and the external shape size of internal mold is consistent with the endoporus of external mold, inside offers endoporus, internal mold is two to open or open more, the supporting use of briquetting and internal mold, and profile is consistent with the shape suitable for reading of internal mold, drain cap is circular, and is supporting with the external mold bottom; Forge then, take following technology: 1. internal mold is put into external mold and compress, form a complete mould; 2. the blank after the heating is put into the internal mold die cavity; 3. briquetting is placed on the blank, within the die cavity; 4. forging and pressing are pressed into briquetting in the die cavity, make blank deformation be full of die cavity; 5. mention a whole set of mould, be placed on the drain cap, the punching press briquetting makes briquetting and internal mold deviate from external mold, separates briquetting then, and internal mold takes out the satin base and gets final product, and finishes a forging stock program.
The present invention takes technique scheme, has following beneficial effect: the present invention is easy than the prior art demoulding, and the mould that need not reverse has changed the mode of the demoulding, saves labor, and speed is fast, the efficient height.Because internal mold is in light weight, easily carrying, easily cooling, and can do several cover internal molds and use in turn, prolonged the service life of mould, reduced the forging cost.The present invention is easy to operate, and low consumption is applicable to the forging molding of round and special-shaped flange shaft.
The specific embodiment
Describe in detail below in conjunction with the present invention of embodiment.
Embodiment
The present invention is a kind of forging method of flange shaft, takes following steps:
1. at first prepare the specific complex mould, this composite die includes: external mold, internal mold, briquetting, drain cap, external mold are round busses that tapered endoporus is arranged, and last hole is little, and following hole is big, and inwall has the tapering of 2～3 degree, and such design is convenient to external mold and internal mold and is thrown off; The external shape size of internal mold is consistent with the endoporus of external mold, and inside is an endoporus the same with required flange shaft blank type shape size, and internal mold is two to open or open more, looks the external type shape of flange shaft and determines; The supporting use of briquetting and internal mold, profile is consistent with the shape suitable for reading of internal mold, and drain cap is circular, and is supporting with the external mold bottom, plays the effect that external mold makes things convenient for internal mold to deviate from from external mold of raising;
2. internal mold is put into external mold and compress, form a complete mould;
3. the blank after the heating is put into the internal mold die cavity;
4. briquetting is placed on the blank, within the die cavity;
5. forging and pressing are pressed into briquetting in the die cavity, make blank deformation be full of die cavity;
6. mention a whole set of mould, be placed on the drain cap, the punching press briquetting makes briquetting and internal mold deviate from external mold, separates briquetting, internal mold then, takes out the satin base and gets final product.
Claims (2)
1. the forging method of a flange shaft is characterized in that it may further comprise the steps:
(1) preparation specific complex mould, this composite die includes: external mold, internal mold, briquetting, drain cap, external mold is a round buss that tapered endoporus is arranged, the external shape size of internal mold is consistent with the endoporus of external mold, and inside offers endoporus, and internal mold is two to open or open more, the supporting use of briquetting and internal mold, profile is consistent with the shape suitable for reading of internal mold, and drain cap is circular, and is supporting with the external mold bottom;
