Current production requirement.FMT is to apply pressure to metal stock using metal forming machinery, it is produced plastic deformation to obtain
There must be the processing method of certain mechanical performance, definite shape and size forging, can eliminate metal by forging was smelting
The defects of caused as cast condition is loose in journey, optimize heterogeneous microstructure；Simultaneously because saving complete metal streamline, therefore forge
The mechanical performance of part generally to be preferred over the casting of same material.And the warm forging carried out below the recrystallization temperature of steel and higher than normal temperature
Technique is highly effective for the precision and quality for improving forging, does not have cold forging plastic force big like that, applies in general to confront
The forging molding of amount and the higher part of required precision.But even with such technique, for the precision of some parts
Still suffer from problem, such as a kind of axle sleeve of long size as shown in Figure 1 during forging processing, its overall length typically in more than 250mm,
And the wall thickness of axle sleeve is smaller, typically in 10mm or so, the forging processing for this axle sleeve, using current warm forging technique
When being forged, due to the descending stroke length of mould, the speed that mould pushes should not control, and be easy to cause to produce on part and split
The problems such as line, interlayer, folding, fraction defective is very high, causes the significant wastage in production.
Therefore, in order to improve the quality of forging, it is necessary to improve to existing production equipment and process, a kind of forging is designed
The forging process equipment that part quality is higher, yield rate is higher.
Utility model content
The problem of in existing forging processing technology, the purpose of this utility model is to provide a kind of long size axis tube cavity
Fine forging forming die, the yield rate of the relatively thin long size axis tube components of wall thickness can be greatly improved, ensure the quality of part, reduced
Waste.
To reach the purpose of this utility model, a kind of long size axis tube cavity fine forging forming die of the present utility model includes
The fill block that mould and workbench are fixed, fill block central position set the push rod being connected with hydraulic system, are arranged on fill block
The constrained system guard ring of side, its inner side are provided with constrained system；Cavity plate is set above constrained system guard ring, and it includes die sleeve, mould
Benevolence and die cavity, die are provided with guide groove；Described constrained system includes the bottom plate fixed with fill block, top plate, with guide groove
The lead of cooperation and the spring being arranged between bottom plate and top plate, the top plate are provided with the pressure pin coordinated with die cavity, institute
State push rod to be connected with top plate, described pressure pin is to be coaxially disposed with die cavity.
Preferably, described spring is to be symmetrical arranged a pair or two pairs.
Further preferably, described spring is set on lead.
The beneficial effects of the utility model are the long size axis tube cavity fine forging forming die, to set in a mold about
Beam system, the punch-pin downstream rate in forming process is reasonably controlled, can be effectively prevented from producing in forming process
Crackle, interlayer, the defects of being even broken is folded, greatly improve the yield rate of shaping, reduced and waste, improve production efficiency.

S3：It is anti-to squeeze, above-mentioned belt restraint ssytem is formed according to the suitable spring of the selections such as the material, size, wall thickness of central siphon
Mould, by forge it is thick after material be put into it is counter in mould squeezed, carry out central siphon shaping；
S4：Go to take, by the lower end closure scrap (bridge) excision by the central siphon of the anti-extrusion forming of mould；
S5：Finishing, to going the central siphon after taking to carry out finishing, ensure the performance and surface quality of part.
Above-mentioned moulding process of the present utility model, before the anti-extrusion forming of central siphon, according to the material and size of material, including
The factor such as overall length and wall thickness selects suitable spring to form the constrained system of mould, in this way, working as forging and stamping punch-pin to mould type
When the blank of intracavitary carries out anti-crowded central siphon, the lower end of blank abuts with the pressure pin of constrained system, utilizes the spring in constrained system
Elastic force the downstream rate of punch-pin is controlled, avoid punch-pin downstream rate is too fast from causing to crack during anti-squeeze, press from both sides
Layer, fold the defects of being even broken.The specifically chosen of spring can be carried out tentatively according to central siphon material and the different of specific size
Calculating and carrying out limited experiment to draw, the utility model is not described in detail and limited to this.
Long size axis tube cavity fine forging forming die of the present utility model and moulding process, constraint system is set in a mold
System, is reasonably controlled the punch-pin downstream rate in forming process, can be effectively prevented from producing in forming process many
The defects of, the yield rate of shaping is greatly improved, reduces and wastes, improves production efficiency.
The utility model is not limited to described embodiment, those skilled in the art do not depart from it is of the present utility model
In the i.e. open scope of spirit, it can still make some amendments or change, therefore rights protection scope of the present utility model is with claims
The scope of restriction is defined.
