Description
Technical field
This utility model relates to metal stamping processing technique field, has the stamping die of side channel structure stamping parts particularly to a kind of low cost, in high precision processing.
Background technology
Fig. 1 is that I takes charge of the stamping parts 1 accepted on die sinking a door lock producing, has a side channel 11 in the side of its structure.It is used for processing this stamping parts 1 and there are two kinds of techniques:
Method one is the agent structure that tablet rounded for main region is first drawn into rotation body structure, goes out side channel 11 the most again.Because side channel 11 is on the side, so needing when being processed to use complicated side blow structure, this will increase the cost of diel.
Method two is the tablet 1 ' (as shown in Figure 2) first cutting out and having breach 11 ', and then twice Pressing Deformation becomes desired structure.This method diel low cost, but new problem can be brought.The deformation of side channel 11 breach 11 ' to be passed through obtains, but tablet 1 ' is along ring 12 ' drawing process, and breach 11 ' can affect tablet 1 ' material respectively to the uniformity of flowing, and the consequence brought is that last side channel 11 deepens.
Owing to client is very tight to stretching side channel 11 size tolerance requirements, so the most often using first method, but being because cost increase, lacking competitiveness.
Therefore, it is necessary to provide a kind of new stamping die to solve the problems referred to above.
Utility model content
Main purpose of the present utility model is the stamping die providing a kind of low cost, high accuracy processing to have side channel structure stamping parts.
This utility model is achieved through the following technical solutions above-mentioned purpose: a kind of processing has the stamping die of side channel structure stamping parts, including the male model being oppositely arranged and master mold, described male model has the through movable holddown in middle part and the draw punch through described movable holddown, described master mold includes just to the fixed stop of described movable holddown and just leveling drift to described draw punch, the both sides of described draw punch are respectively provided with a groove, contain telescopic active block stop between described movable holddown and described groove.
Concrete, described active block stop is set to arcs of recesses towards the medial surface of described draw punch.
Concrete, the side of described draw punch is provided with R angle step.
Further, the top of described active block stop has internal projection.
Concrete, described fixed stop is provided with the escape groove of two described active block stops of correspondence.
Using technique scheme, technical solutions of the utility model provide the benefit that:
1, this stamping die can ensure formed precision in the case of being added without side blow structure, saves die cost, but has reached higher formed precision；
2, R angle step can strictly control the deflection outside tablet, prevents contoured edge R angle the least and brings the problem easily broken；
3, internal projection can provide the oblique contact of turning point, R angle material, and such thrust is more reliable；
4, escape groove is avoided that barrier activity block, it is ensured that compress material near breach, it is ensured that precisive shaped degree.

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described in further detail.
As shown in Fig. 2, Fig. 3, Fig. 5 to Fig. 7, a kind of processing of the present utility model has the stamping die of side channel structure stamping parts, including the male model 1 being oppositely arranged and master mold 2, male model 1 has the through movable holddown 21 in middle part and the draw punch 22 through movable holddown 21, master mold 2 includes just to the fixed stop 31 of movable holddown 21 and just leveling drift 32 to draw punch 22, the both sides of draw punch 22 are respectively provided with a groove (mark), contain telescopic active block stop 23 between movable holddown 21 and groove.During matched moulds, movable holddown 21 can first push down the periphery of tablet 1 ', tablet 1 ' position is made to fix, so latter two active block stop 23 pushes down the upper material near breach 11 ' position of tablet 1 ', subsequently tablet 1 ' is made to deform near ring 12 ' by draw punch 22, in the process, leveling drift 32 can coordinate draw punch 22 to clamp tablet 1 ' mid portion material, makes Pressing Deformation put in place.Because active block stop 23 and movable holddown 21 phase are independent, thus ensuring that the pressure of material inner to breach 11 ', reducing the flowing of breach 11 ' region material during this Pressing Deformation, so when next step molding side channel, structure precision is the highest.Utilize this stamping die can ensure formed precision in the case of being added without side blow structure, save die cost, but reached higher formed precision.
As shown in Figure 6, active block stop 23 is set to arcs of recesses towards the medial surface of draw punch 22.The border deformed due to tablet 1 ' is rounded, therefore active block stop 23 and the contact portion boundary shape to be fitted of tablet 1 '.
As it is shown on figure 3, the side of draw punch 22 is provided with R angle step 221.Owing to tablet 1 ' outside to be also deformed into tubular structure in next step, so the deflection in outside is also required to strictly control, prevents contoured edge R angle the least and bring the problem easily broken.
As it is shown on figure 3, the top of active block stop 23 has internal projection 231.Tablet 1 ' always has R angle at the boundary of deformation, and internal projection 231 can provide the oblique contact of turning point, R angle material, and such thrust is more reliable.
As it is shown in fig. 7, fixed stop 31 is provided with the escape groove 311 of two corresponding active block stops 23.Always can be thinning after material flowing, but fixed stop 31 is rigid member, and upper surface will not follow material thickness variation, so it is likely to be formed the obstruction to active block stop 23, if this thing happens, active block stop 23 just loses and compresses the function of material near breach 11 ', brings the failure of precision controlling；Escape groove 311 is just avoided that barrier activity block 23, it is ensured that compress material near breach 11 ', it is ensured that precisive shaped degree.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, on the premise of creating design without departing from this utility model, it is also possible to making some deformation and improvement, these broadly fall into protection domain of the present utility model.
