Abstract
The utility model discloses an extrusion device which comprises an extrusion rod, an extrusion cylinder, an extrusion die, a die cushion, a forging hole, a shell and a blank. The extrusion cylinder is arranged in the shell in a penetrating mode. One end of the extrusion cylinder is provided with the extrusion rod and the other end of the extrusion cylinder is provided with the die cushion. The die cushion is provided with the extrusion die. The blank is arranged in the extrusion die. The forging hole is formed in the die cushion in a penetrating mode. The extrusion device has the advantages of decreasing influence of friction, being homogenous in transformation, reducing additive tensile stress and apparently improving organization and performance of a forge piece.
Description
Technical field
The utility model relates to a kind of pressurizing unit.
Background technology
Form and part dimension differ, shape, material and the structure of part commonly used are different, method for metal working is also varied, and forge the continuity that processing can guarantee metal fibrous tissue, and the fibr tissue of forging and forging profile are consistent, metal streamline is complete, can guarantee that part has the service life of good mechanical property and length, so forging has very important status in metal working process, but with some inductile materials when forging, just be not easy processing.
The utility model content
Goal of the invention: the purpose of this utility model is in order to solve the deficiencies in the prior art, to provide a kind of simple in structure, and working stability is reliable, and distortion evenly and can significantly improve the tissue of forging and the pressurizing unit of performance.
Technical scheme: in order to realize above purpose, a kind of pressurizing unit described in the utility model, it comprises: pressure ram, recipient, extrusion die, die-cushion, forging hole, housing and blank, be equipped with recipient in the described housing, one end of recipient is provided with pressure ram, and the other end of recipient is provided with die-cushion, and described die-cushion is provided with extrusion die, be provided with blank in the extrusion die, be equipped with the forging hole on the described die-cushion.
Be provided with liquid in the described recipient.
One side of described pressure ram is provided with pressure gauge.
The radial skew face of described pressure ram is provided with pad, also is provided with pad on the radial skew face of described extrusion die.
Beneficial effect: a kind of pressurizing unit that the utility model provides, by pressure ram liquid is compressed, thereby so that the static pressure of liquid acts on the blank, make blank pass through the forging hole and produce plastic deformation, thereby obtain the forging of required form, this pressurizing unit has reduced the impact of friction, and distortion evenly, reduce additional potential stress, and can significantly improve tissue and the performance of forging.
Description of drawings
Fig. 1 is full sectional view of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
As shown in Figure 1, a kind of pressurizing unit described in the utility model, it comprises: pressure ram 1, recipient 3, extrusion die 4, die-cushion 5, forging hole 6, housing 8 and blank 9.
Be equipped with recipient 3 in the described housing 8, an end of recipient 3 is provided with pressure ram 1, and the other end of recipient 3 is provided with die-cushion 5, and described die-cushion 5 is provided with extrusion die 4, is provided with blank 9 in the extrusion die 4, is equipped with forging hole 6 on the described die-cushion 5.The radial skew face of described pressure ram 1 is provided with pad 7, also is provided with pad 7 on the radial skew face of described extrusion die 4.
When using the utility model, the hydraulic fluid 2 of in recipient 3, packing into, the pressure ram 1 that then gasket seal 7 will be housed moves downward, liquid 2 is compressed, in recipient 3, producing very large hydrostatic pressure acts on the blank 9, make blank 9 produce plastic deformation by forging hole 6, obtain the forging 11 of required form, and a side of pressure ram 1 is provided with the force value that pressure gauge 10 is used for showing liquid 2, with the flowing velocity of reflecting liquid blank 9, prevents the energy sudden outburst of extrusion die 4 interior storages, liquid blank 9 and liquid 2 times sprays from forging hole 6 with high speed, with assurance safety.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalents or modifications of having done according to the utility model Spirit Essence all should be encompassed within the protection domain of the present utility model.
