The needs of the Flexible Productions such as change, small lot, especially in the production of the complex partses of some varying dimensions, such as style
Different the automobile even sample car of small lot, automobile body covering piece is produced using conventional ones process, die cost compared with
For costliness, the production cycle is more very long, and in other manufacture fields such as kitchen tools industry, medical industry and electrical apparatus industry etc. generally need
Some small lots and the complex product of appearance and size are wanted, using traditional production technology not only forming difficulty and production cost
It is higher；
3. multiple working procedure is generally required using traditional Sheet Metal Forming Technology and more molds can stamp out it is satisfactory
Product, during stamping, mould directly contacts with plate, mutually extruding, greatly reduces the rigidity of formed product
And intensity, the reduction of sheet material is increased, or even cause the corrugation and rupture of product；
4. by the way of manual metal plate, although cost can be reduced, the cycle is oversize and the quality of product is difficult to ensure that.
Utility model content
The purpose of this utility model be to provide it is a kind of it is being used with hydraulic expanding type complete sets of Techniques, can adapt to flexible metaplasia
The metal sheet forming mould of production demand is insufficient existing for above-mentioned prior art to overcome.
The utility model adopts the technical scheme that：A kind of metal sheet forming mould, including upper die and lower die, under described
Mould is pattern, and upper mould is empty mould, and the lower mould is inverse-T-shaped structure, including lower mold body and is connected at left and right sides of lower mold body
Lower-left picks up the ears to pick up the ears with bottom right, and the lower surface picked up the ears under left and right and the lower surface of lower mold body are in same plane, and lower mold body protrudes
The upper surface picked up the ears under left and right, is provided with lower mode cavity in the middle part of lower mold body, and the lower mode cavity is and plate parts shape pair to be produced
The cavity plate answered, lower mode cavity bottom are provided with steam vent, and the upper surface of lower mold body is provided with symmetrically arranged alignment pin；
The upper mould is " T " shape structure, including upper die body is picked up the ears with the upper left being connected at left and right sides of upper die body and upper right
Pick up the ears, it is left and right on the upper surface picked up the ears and the upper surface of upper die body be in same plane, upper die body protrudes what is picked up the ears on left and right
Lower surface, be provided with upper cavity in the middle part of the upper die body, be provided with upper cavity respectively with the oil inlet on front side of upper die body and rear side
The through hole that oil-out communicates, the annular mounting groove for being used for installing sealing ring, upper die body are provided with around the periphery of upper cavity die cavity mouth
Lower surface be provided with symmetrically arranged dowel hole, dowel hole is corresponding with the alignment pin on lower mold body face during upper and lower mould matched moulds
Coordinate, upper cavity is relative mouth to mouth with lower mode cavity, and upper cavity forms the liquid room for irrigating high-voltage oil liquid during use.
Its further technical scheme is：The oil inlet and oil-out are shoulder hole, and shoulder hole periphery is provided with for pacifying
The screwed hole of ring flange is filled, oil inlet and oil-out are connected by shoulder hole and ring flange with external oil pipe during use.
Further：The upper die and lower die are made of die steel material.
Due to taking above-mentioned technical proposal, a kind of metal sheet forming mould of the utility model has below beneficial to effect
Fruit：
1. the utility model is the mould used with hydraulic expanding type complete sets of Techniques, smoothly slowly connect with plate by fluid
Touch, continuously load hydraulic pressure, can not only effectively improve the rigidity and intensity of shaped sheet, reduce being thinned for sheet material, suppress sheet material
Corrugation and rupture, ensure the quality of shaping, and the complex-shaped surface mould that conventional ones technology can not process can be processed
Part, it is suitable for the demand that product small lot, variation, physical dimension are complicated in modernization of industry development；
2. production process only needs one set of die once to complete to process（Traditional Sheet Metal Forming Technology processed complex part is past
Multistep process is carried out toward more molds are needed）, so as to substantially reduce the production cycle of the process-cycle of mould and part, reduce
The cost of production；
3. the oil inlet and outlet of the utility model is located at front and back sides, above pick up the ears to be in same plane with upper die body upper surface,
Can be bonded with the working face of forcing press, under pick up the ears to be in same plane with lower mold body lower surface, can with forcing press install table top patch
Close, not only contribute to that upper/lower die is fixed on forcing press acting surface by stationary fixture, implementation is provided by external pressure machine
Controllable pressure-pad-force, so as to provide more accurately processing technology and parameter, improve the forming quality of part；And can have
The position of the fixed upper/lower die of effect, prevents off-centring occur during matched moulds；
Coordinated 4. the utility model enters oil outlet by shoulder hole and ring flange, enter oil outlet periphery and be provided with four screw threads
Hole, flange is fixed by screw, good airproof performance；
5. the upper and lower mould of the utility model by one group of positioning finger setting, is compressed by forcing press and applies pressure-pad-force, without
Clamping screw separately is set, uniform flanging can either be ensured so that the sheet material of flanging part uniformly can internally flow feed supplement, again
Drawback caused by bolt connection can be avoided：
（1）Bolt connection because flanging it is uneven caused by product defects；
（2）Matched moulds and die sinking process need to carry out bolted installation and removal, be delayed the time of process, production effect
Rate is low（This mould need to only control external pressure machine top acting surface to drive upper mould to be lifted up separating realization die sinking with lower mould）；
（3）The tensile strength of bolt is limited, and the thread damage of bolt easily occurs when needing to provide larger hydraulic coupling
Bad the problems such as, flanging and follow-up dismounting are influenceed, or even bolt fracture occurs, trigger security incident（This mould can adapt to compared with
The production of product under big hydraulic coupling operating mode, and security is more preferable）.
The technical characteristic of metal sheet forming mould of the utility model a kind of is made with reference to the accompanying drawings and examples into
The explanation of one step.
