Abstract
The invention discloses an extrusion device, which comprises an extrusion rod, a container, an extrusion die, a die pad, a forge piece hole, a shell and a blank, wherein the container penetrates through the shell, the extrusion rod is arranged on one end of the container, the die pad is arranged on the other end of the container, the die pad is provided with the extrusion die, the blank is arranged in the extrusion mould, and the forge piece hole penetrates through the die pad. According to the extrusion device, the influence of friction is reduced, deformation is uniform, the additional tensile stress is reduced, and structure and performance of a forge piece are remarkably improved.
Description
Technical field
The present invention relates to a kind of pressurizing unit.
Background technology
Form and part dimension differ, shape, material and the structure of part commonly used have nothing in common with each other, 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 good mechanical performance and long service life; So forging has critical role in metal working process, but with some inductile materials when forging, just be not easy processing.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of simple in structure in order to solve the deficiency of prior art, and working stability is reliable, and distortion evenly also 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 of the present invention, 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 present invention provides, compress liquid through pressure ram, thereby make the static pressure of liquid act 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 influence of friction, and distortion evenly; Reduce additional potential stress, and can significantly improve the tissue and the performance of forging.
Description of drawings
Fig. 1 is a full sectional view of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention.
As shown in Figure 1, a kind of pressurizing unit of the present invention, 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 use is of the present invention, the hydraulic fluid 2 of in recipient 3, packing into, the pressure ram 1 that gasket seal 7 will be housed then moves downward; Liquid 2 is compressed, in recipient 3, produce very big hydrostatic pressure and act on the blank 9; Make blank 9 produce plastic deformation, 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 through forging hole 6; Flowing velocity with reflecting liquid blank 9; The energy that prevent storage in the extrusion die 4 discharge suddenly, and liquid blank 9 and liquid 2 times sprays from forging hole 6 with high speed, with assurance safety.
The foregoing description only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
