Pit slot 41 is rushed, second concave template 11 is provided with for rushing aluminium film second to rush pit slot 112 in advance.Described second rush pit slot 112 by
Bottom wall and the side wall upwardly extended from bottom wall surround, and the side wall is aduncate circular arc type from top to bottom, the exhaust outlet
111 are set to the described second bottom wall for rushing pit slot 112.
Second flexible adjustment mechanism 10 is identical as the structure of the first flexible adjustment mechanism, and working principle is also identical, herein not
It repeats again.First concave template 4 is provided with first and rushes pit slot 41, and first to rush pit slot 41 be through slot, and the second concave template 11 is provided with the
Two rush pit slot 112, and second rushes the side wall that pit slot 112 includes bottom wall and upwardly extends from bottom wall, and the exhaust outlet 111 is set to institute
It states the second bottom wall for rushing pit slot 112 aluminium film is placed between top board and concave template when rushing shell in advance, by the second pressing plate
Air inlet 91 be passed through compressed air, under the action of compressed air, force the aluminium film being compacted to the concave template below aluminium film
On open up second rush 112 Direction distortion of pit slot, second rush air in pit slot 112 by aluminium film deformable squeeze from exhaust outlet
It is discharged in 111, the position for making aluminium film rush pit slot 112 second is rushed out a plastic deformation pit, and the deflection of aluminium film can be with
The pressure and duration of ventilation of the size for rushing pit slot 112 by second and the compression control being passed through control, and by second rush pit slot 112
The size being dimensioned to no more than the first punching slot, effect is to eliminate pre- rush in shell operation the casing forming that liquidates as far as possible
Influence.Aluminium film after rushing shell operation in advance carries out rushing casing forming through overshooting shell molding device C, uses the first punching mechanism 2
Drawing is carried out to aluminium film, that completes aluminium film rushes casing forming, rushes casing forming and needs aluminium film position accurate, compresses aluminium film, eliminates pre- punching
The trace of shell.The second punching mechanism in the present embodiment is the air ram structure used, can also be adopted in other embodiments
With other impact styles.
Rouno Cormer Pregrinding Wheel surdimensionnement is set by the side wall that second rushes pit slot 112, avoids generating during rushing shell in advance obvious
, be not easy the plastic deformation trace eliminated.
Embodiment two.
As shown in fig. 6, the present embodiment the difference from embodiment 1 is that: in the present embodiment, the first pressure regulating mechanism
It further include the first lower platen 7 being set between first concave template 4 and the first flexible adjustment mechanism 5, described first pushes
The bottom surface of plate 7 is provided with multiple for positioning the locating slot of the power output bar 52.
The first concave template 4 is stainless steel material in the present embodiment, to make the first concave template 4 have certain deformation behavior, then
The thickness of first concave template 4 is smaller, only 3-8mm, then causes the depth in aluminium film punching hole only limited, when needing to deepen aluminium film
When scour hole depth, need to increase the first lower platen 7, the shape of the first lower platen 7 is approximate with the first concave template 4, opens up among it
There is third to rush pit slot 71, the first lower platen 7 is located between the first concave template 4 and the first flexible adjustment mechanism 5 for deepening aluminium
The scour hole depth of film.It is (not shown) for positioning power output bar 52 that the bottom of first lower platen 7 is provided with multiple locating slots.First
Lower platen 7 designs simply, select the above material the first lower platen 7 that be to meet the easily deformable spy of the first lower platen 7
Property, cooperate the first concave template 4 and the first flexible adjustment mechanism 5 to eliminate between the first top board 3, aluminium film and the first concave template 4
Parallelism error, uniform and dispersion compression aluminium film.
Above-described embodiment is the preferable implementation of the present invention, and in addition to this, the present invention can be realized with other way,
Do not depart under the premise of present inventive concept it is any obviously replace it is within the scope of the present invention.
