The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done concrete introduction.

Shown in Fig. 1 to 3, the continuous stamping die that is applicable to the mobile phone cam assembly of the utility model mainly comprises: go up module and following module.

Last module comprises: a plurality of extruding drifts 1 that are used to accomplish the thin process of bat; The train wheel bridge 2 that is used for clamping and fixed press drift 1, as continuous stamping die, extruding drift 1 all is fixed on the train wheel bridge 2; Be fixedly mounted on the upper bolster 3 of train wheel bridge 2 tops; Be used to be installed in the upper padding plate 4 between train wheel bridge 2 and the upper bolster 3; Being arranged at train wheel bridge 2 belows is slidingly connected with extruding drift 1 and supplies its baffle plate that passes 5 and stripper plate 6, baffle plate 5 to be used for backstop train wheel bridge 2 control punching strokes; Stripper plate 6 is positioned at baffle plate 5 belows, is used for contacting with material and when the extruding drift lifts, pushing down material and realize taking off material; Be provided with rebound spring 7 between upper bolster 3 and the baffle plate 5, be used for realizing resetting, for punching press is next time prepared.

Following module comprises: the lower bolster 8 of upper face level; Lower bolster 8 is formed with a plurality ofly goes into piece with extruding drift 1 corresponding counterdie; Counterdie is gone into piece and is comprised that a plurality of bats approach to return into piece 10 and one and put in order into piece 11, is successively set on the lower bolster 13 and die shoe 14 of lower bolster 8 belows.

A plurality of bats approach a plurality of bats that all are formed with the preprocessing groove of the vertical sidewall of having of depression into piece 10 and approach into piece 10; Bat approach into piece 10 be positioned at its forming pockets around be formed with the compressive plane 12 that becomes certain inclination alpha with horizontal plane; The bat that compressive plane 12 is used to material is carried out gradually approaches; As shown in Figures 2 and 3, the gap size between the sidewall of forming pockets is promptly clapped and is approached into the cutting edge gap size f of piece 10 with the reducing and reduce of inclination alpha, and it is identical that final sum is returned the cutting edge gap size of putting in order into piece 11; Return and put in order the forming face that has processing final goal shape into piece 11, with processing final size and profile.Bat with different angle approaches to return into piece 10 and one and puts in order into piece 11 combinations; The target size that purpose is to make the size of the middleware 16 that processes to approach final products 15 gradually; Make it finally add man-hour returning to put in order in the piece 11; The size of boss peripheral structure 15b increases machining accuracy near final size.

In addition; Following module comprises that also being used to increase counterdie goes into the pressure-plate-force of piece and nitrogen spring 9 one to one with it; The nitrogen spring volume is little, elastic force is big, elastic force pressure is constant, and having guaranteed has enough big pressure-plate-force when the stamping-out profile, makes product have good flatness.In addition, the above-mentioned part material of going up module and following module all can adopt high-speed steel SKH-9 to process.

A plurality of bats approach into piece 10 with return all identical that is to say of the height put in order into all forming pockets of piece 11 and just directly boss be worked into size when the first time preprocessing.

As a kind of preferred version, to clap to approach and be provided with 6 into piece 10, the number of degrees of the inclination alpha that their compressive plane 12 is become with horizontal plane are followed successively by 8 degree, 6 degree, 4 degree, 3 degree, 1 degree, 0 and spend.The cutting edge gap size f that bat approaches into piece 10 becomes arithmetic progression; The tolerance of arithmetic progression is d, as preferred version, if calculate according to the monolateral of cutting edge gap; Tolerance d equals 0.025mm; The bat that the inclination alpha number of degrees are more little approaches into the cutting edge gap size f of piece 10 more little, returns the cutting edge gap size f put in order into piece 11 and equals to clap and approach into the minimum cutting edge gap size of piece 10, that is to say that the minimum bat of cutting edge gap size f approaches into piece 10 and do not have surplus.

The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the utility model.
