Description
Technical field
The present invention relates to machining equipment field, especially a kind of contiguous block forging mold.
Background technology
In the prior art, the forging for the contiguous block on compressor all uses cold forging pattern, and the thick embryo of use is with being connected
The shape of block is substantially similar, simply carries out the dimension limitation of size each side in cold forging processes to contiguous block；But forging
Cheng Zhong, due to needing larger extruding force, big pressure can be diffused to upper mold core, lower mold core respectively from die cavity, can cause,
Larger contraction can occur for lower mold core, ultimately cause die life lowly, production cost is high.
The content of the invention
There is provided a kind of simple in construction the invention aims to solve the deficiency of above-mentioned technology, can effectively improve
The ability of pressure is born during forging, it is ensured that the contiguous block forging mold of die life.
In order to achieve the above object, a kind of contiguous block forging mold designed by the present invention, it includes upper bolster, lower mould
Seat, is respectively arranged with cushion block on upper bolster and die shoe, is provided with upper bolster on upper mold core, die shoe and is provided with lower mould
Core, is respectively arranged with die cavity, upper mold core and the die cavity and the shape of contiguous block after lower mold core cooperation in upper mold core and lower mold core
Unanimously；Described upper mold core is at least two layers of nested structure, and described die cavity is arranged on the center of nested structure, described
Lower mold core be at least two layers of nested structure, and described die cavity is arranged on the center of the nested structure；In lower mold core
Die cavity is provided centrally with jogger hole straight down, in the through hole being provided centrally with straight up of the cushion block of die shoe, described
Through hole cover whole jogger hole, push rod enters jogger hole through through hole.
Above-mentioned technical proposal, upper mold core and lower mold core, can be in forging processes by multilayer nest structure, will be upper and lower
When core rod is extruded, contiguous block can carry out the scattered of power to the extruding force of die cavity by multilayer nest structure, so that capable diffusion
More stablize, it is ensured that the service life of upper and lower core rod.Even and if after die cavity is damaged after a long time use, also only needing to
One piece of center for changing multilayer nest structure just can be to greatly reduce replacement cost.
Described upper mold core includes core print seat, the middle collar and outer sleeve, in three layers of nested structure；Wherein described die cavity is set
On core print seat, and core print seat is truncated cone shape, and described die cavity is arranged on the less end face of core print seat diameter, each portion of the middle collar
The consistency of thickness of position, and the medial surface of the middle collar fits with the lateral surface of core print seat；The medial surface of described outer sleeve and the middle collar
Lateral surface laminating.Described lower mold core equally includes core print seat, the middle collar and outer sleeve, in three layers of nested structure；It is wherein described
Die cavity be arranged on core print seat, and core print seat is truncated cone shape, and described die cavity is arranged on the less end face of core print seat diameter, middle set
The consistency of thickness at each position of ring, and the medial surface of the middle collar fits with the lateral surface of core print seat；The inner side of described outer sleeve
Fitted with the lateral surface of the middle collar in face；Described jogger hole is located at core print seat centre position.Upper and lower core rod passes through three layers of nested knot
Structure, can be more uniform by pressure dissipation when forging contiguous block, and stability is higher.
Limited block is provided between described upper bolster, die shoe.Limited block be avoided that above and below core rod when forging
Collide and damage.
The material that described upper mold core, lower mold core are selected pulls out material for the upsetting three of electroslag remelting three.Described upper mold core, lower mould
The cavity surface of core is handled by physical vaporous deposition.The structure can improve above and below core surface hardness and anti-wear performance,
Performance and service life are more long.
A kind of contiguous block forging mold obtained by the present invention, it to upper mold core, lower mold core using three layers of nesting by being tied
Structure, the pressure in forging process greatly can be disperseed, be avoided that pressure is excessive and causes the destruction of die cavity one by one, be improved
The mold use life-span, while ensuring the quality of product forging.
