Description
Technical field
The present invention relates to technical field of mold, is specifically a kind of drawing die for the manufacture of axial lock case.
Background technology
Have a kind of lockset being called as axial lock at present, this lockset comprises axial lock case, is thin-wall part, concrete structure as marked shown in 26 in Fig. 1 or 2, although utilize more existing technology also can produce, such as machining, but stability of the production process is poor, yield rate is lower.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of stability of the production process good, the drawing die for the manufacture of axial lock case that yield rate is higher.
Technical scheme of the present invention is, the present invention is for the manufacture of the drawing die of axial lock case, and it comprises die shank, cope match-plate pattern, upper die plate, be provided with the upper mounted plate of punch, first elastomer, stripper plate, lower bolster, counterdie backing plate, bottom plate, dynamic model cover, counterdie, dynamic model, described cope match-plate pattern, upper die plate, upper mounted plate, first elastomer, stripper plate sequentially connects from top to bottom, described lower bolster, counterdie backing plate, bottom plate, dynamic model cover, counterdie sequentially connects from bottom to top, described punch and the first elastomer, the first hole sliding fit that the described punch of the confession arranged in stripper plate passes to enable punch bottom stretch out outside the first hole and to enter in the forming hole arranged in counterdie in matched moulds process, this forming hole sliding fit one dynamic model, the second hole sliding fit that the described dynamic model of confession that described dynamic model is arranged in also overlapping with dynamic model passes, the lower end of described dynamic model is arranged in the 3rd hole for dynamic model described in axial limiting being arranged on bottom plate, described lower end and described 3rd hole sliding fit, described lower end and is through lower bolster, counterdie backing plate offsets with the one end entering the knock-pin in described 3rd hole, the below of the knock-pin other end arranges a supporting plate, second elastomer is set between supporting plate and knock-pin, second elastomer one end and the knock-pin other end offset, the second elastomer other end and supporting plate offset, be provided with at least three suspension rods of the spacing for changing supporting plate and lower bolster between supporting plate and lower bolster, each suspension rod one end is connected with supporting plate, and each suspension rod other end is connected with lower bolster.
Operation principle of the present invention is, die shank, cope match-plate pattern, upper die plate, be provided with the upper mounted plate of punch, first elastomer, stripper plate forms part of the upper die, remaining part forms part of the lower die, first raw material are placed on counterdie, then, part of the upper die and part of the lower die matched moulds, stripper plate, first lower bolster contacts, then the first elastomer is compressed, cause the first elastomer, stripper plate entirety is upwards retracted, simultaneously punch bottom to be stretched out outside the first hole and is entered in the forming hole arranged in counterdie, punch bottom enters in the forming hole process arranged in counterdie, can raw material be headed in forming hole, and dynamic model is headed on downward rollback, due to the second elastomeric effect, punch bottom, raw material, dynamic model will move downward with certain speed and dynamics together, the whole process that moves downward is the process that a speed and strength all changes, the dynamics that fast but the second elastomer of speed in early stage provides is little, the great efforts that slow but the second elastomer of later stage speed provides, by regulating suspension rod, debug out different speed and strengths, and the state that final acquisition one is comparatively stable, the described process that moves downward is exactly forming process, described speed and strength ensures that stability of the production process is good just, the reason that yield rate is higher, when after shaping completing, die sinking, punch bottom, product, dynamic model moves upward together, and product ejects forming hole the most at last, thus complete product stripping.
After adopting said structure, the present invention compared with prior art, have the following advantages: in conjunction with technique scheme and operation principle known, the mutual cooperation of each parts can realize the drawing and forming of axial lock case, and it is good except having stability of the production process, outside the advantage that yield rate is higher, also have the advantage that processing is simple, raw material are comparatively economized, production efficiency is high that drawing die has concurrently.
As improvement, each suspension rod one end is connected with supporting plate and refers to that each suspension rod one end is exposed outside and nut of screwing on through supporting plate, and supporting plate can move axially along suspension rod under nut regulates; Each suspension rod other end is connected with lower bolster and refers to that each suspension rod other end and lower bolster are spirally connected fixing, like this, easy to adjust, fixing firm again after regulating.
As improvement, the second elastomer runs through at least one guide post, the second elastomer and guide post sliding fit; One end and the knock-pin other end of guide post are spirally connected fixing, the other end of guide post is through supporting plate and expose outside and nut of screwing on, and supporting plate can move axially along guide post under nut regulates, like this, there is provided guiding to the second elastomer motion, make the second elastomer motion more stable.
As improvement, it also comprises upper end and is pressed abd fixed on lead on cope match-plate pattern by upper die plate, its underpart is sequentially through exposing outside after upper die plate, upper mounted plate, the first elastomer, stripper plate, run through counterdie, dynamic model cover, bottom plate pilot hole in matched moulds process with described bottom sliding fit, like this, provide a kind of lead of compact conformation, not only make view picture mould structure compacter, and make folding mould more stable, be more conducive to that stability of the production process is good, yield rate is higher.
