Specific embodiment
For the ease of the understanding of those skilled in the art, below with reference to examples and drawings 1-5 to the utility model make into
The explanation of one step, the content that embodiment refers to not are the restriction to the utility model.
See Fig. 1-3, one kind rushing pit device in advance, including punching mechanism, the top board 1, concave template set gradually from top to bottom
2, the elevating mechanism 4 of pressure regulating mechanism 3 and lift-up pressure regulating mechanism 3, the punching mechanism is air ram structure, described
Top board 1 offers venthole 11, and the concave template 2 offers clearance position 21.
Rushing pit device A in advance includes rack 5, and the rack 5 is provided with top mold holder 51 and lower template 52, and top board 1 is fixed on
The bottom of top mold holder 51, pressure regulating mechanism 3 are set to the top of lower template 52, and elevating mechanism 4 adjusts machine for lift-up pressure
Structure 3.When work, top mold holder 51 and top board 1 are fixed, aluminium film are passed through between top board 1 and concave template 2, and make aluminium
Film is close to top board 1, and 4 lift-up pressure regulating mechanism 3 of elevating mechanism cooperates top board 1 and pressure regulating mechanism 3 and compresses aluminium
Then film inputs compressed air by venthole 11 and carries out punching press, complete an aluminium film and rush hole process in advance.
The pre- of the utility model rushes pit device, and venthole 11 is opened up on top board 1, and it is empty to be passed through compression by punching mechanism
Gas, 21 Direction distortion of clearance position for forcing the aluminium film being compacted to open up on concave template 2 form deformation pit.Deflection passes through
21 size of clearance position of concave template 2 and the pressure of compressed air, gassing time are designed to control.The clearance position 21 of concave template 2
Shell size practical less than aluminum hull should be rushed when size design, effect rushes shell to the shadow for finally rushing shell in advance also for elimination as far as possible
It rings.
The pre- pit device that rushes of the utility model with syzygies shell molding device, make aluminium film first carries out rushing in advance hole processing later again into
Row it is final rush casing forming, rush in advance hole processing has the basis of aluminium film once drawing, rushes casing forming process subsequent
In can reach than in the prior art using once rushing the deeper depth of casing forming, in addition, carrying out rushing shell again after rushing hole in advance and handling
Forming processes so that aluminium film be plastically deformed during rushing casing forming it is opposite without pre- punching hole processing when it is few, be able to achieve more rapidly
Rush casing forming.Aluminium film thickness is concentrated to reduce and be mostly occurred in four angular regions of the aluminum hull of formation, due to having in rushing shell drawing process
Primary pre- punching hole carries out the basis of drawing, and when rushing casing forming, four angular region material flow of aluminum hull loses less, four aluminum corner brace of aluminum hull after stretching
Thickness degree is thicker.
In the present embodiment, the clearance position 21 is surrounded by bottom wall and the side wall upwardly extended from bottom wall, the side wall be from
The aduncate circular arc type under, the bottom wall are provided with exhaust outlet 22.
Rouno Cormer Pregrinding Wheel surdimensionnement is set by the side wall of clearance position 21, avoids generating significantly, no during pre- punching hole
The plastic deformation trace easily eliminated.Under the action of compressed air, force the aluminium film being compacted on the concave template 2 below aluminium film
The clearance position 21 opened up deforms, and the air in clearance position 21 is discharged from exhaust outlet 22 by aluminium film deformable squeeze, makes
Aluminium film is rushed out a plastic deformation pit in the position of clearance position 21.
As illustrated in figures 4-5, in the present embodiment, there are the pressure regulating mechanism 3 multiple elasticity to go out force, and the elasticity goes out
Force acts on the concave template 2, and the concave template 2 can be made to deform.
It is of the invention it is pre- rush pit device, aluminium film is compressed by top board 1 and concave template 2, pressure is provided with below concave template 2
Power regulating mechanism 3, there are the pressure regulating mechanism 3 multiple elasticity to go out force, and during compressing aluminium film, elasticity goes out force
The concave template 2 is acted on, is made by pressure regulating mechanism 3 and the cooperation of concave template 2 tight between top board 1, aluminium film and concave template 2
Closely connected conjunction, to uniformly compress aluminium film, effectively eliminated top board 1, aluminium film and concave template 2 during compressing aluminium film it
Between parallelism error, greatly improve quality and speed that aluminium film rushes casing forming.Pressure regulating mechanism 3 of the invention has
Multiple elastic forces out, can uniformly and the output pressure of dispersion, concave template 2 of the invention have morphotropism, easily deformable, energy
Enough offset the parallelism error bring adverse effect in compaction process between top board 1, aluminium film and concave template 2.Of the invention
Pressure regulating mechanism 3 and concave template 2 cooperate, and convert surface pressure for the point pressure that pressure regulating mechanism 3 exports, then to aluminium film into
Row compresses.
In the present embodiment, the pressure regulating mechanism 3 includes pedestal 31, is movably set in pedestal 31 and through pedestal 31
Multiple power output bars 32 are used for positioned at 31 bottom of pedestal and the gas circuit cylinder manifold 33 that connect with pedestal 31 and at the top of pedestal 31
The limit plate 34 of limit power output bar 32.
Gas circuit cylinder manifold 33 is located at 31 bottom of pedestal and connect with pedestal 31, and 33 external gas source of gas circuit cylinder manifold will simultaneously pass through
Uniform output to pedestal 31 is that power output bar 32 provides pneumatic drive, is subjected to displacement power output bar 32 in a certain range, gas
Dynamic drive force power output bar 32 is subjected to displacement upwards, and jacking concave template 2 is that concave template 2 provides pressing force, when top board 1, aluminium
There are when parallelism error between film and concave template 2, different floating displacements can occur for the power output bar 32 of corresponding position, make concave template
2 compression aluminium films are close to top boards 1 and eliminate parallelism error, simultaneously because the power of power output bar 32 not by the variation of floating displacement and
Variation, keeps the power for acting on concave template 2 uniform and dispersed distribution, and the force for spending force of any one power output bar 32 is all the same.
In the present embodiment, the gas circuit cylinder manifold 33 be hollow form structure, the gas circuit cylinder manifold 33 be provided with it is multiple into
Stomata 331 and multiple ventholes 332；The pedestal 31 offers multiple through slots 311, and the power output bar 32 is installed on the through slot
311；The top of the gas circuit cylinder manifold 33 be provided with it is multiple with the one-to-one groove 333 of the through slot 311, described in each
At least one described venthole 332 is provided in groove 333, the venthole 332 is connected to the through slot 311.
