Further, the technical solution of the utility model can also be:
Gap between the die cavity wall of the periphery wall of described drift and described binder block is 5 μ m.
Gap between the perisporium of the periphery wall of described die plate insert and the stamping space of described die is 5 μ m.
Described drift is made by the powder carbide alloy of high rigidity.
Described die is made by the powder carbide alloy of high rigidity.
Described irregularly-shaped hole has 6.
A kind of high accuracy blanking punching structure of the present utility model only namely can satisfy size and the status requirement of irregularly-shaped hole simultaneously with a step Sheet Metal Forming Technology, also only with satisfying the requirement of product plane degree once the step Sheet Metal Forming Technology, yield rate is high, good product quality, stock utilization increases substantially, and reduces cost.

Fig. 3 is the schematic diagram of the forming punching head of high accuracy blanking punching structure of the present utility model.
The figure number explanation
1, drift 2, binder block 3, die 4, workpiece 5, push rod 6, die plate insert 1.1, hemisection drift 1.2, forming punching head 6.1, hemisection insert 6.2,1.2.1, bulge loop 1.2.2, horizontal ring portion 1.2.3, boss 1.2.4, centre bore 1.2.5, irregularly-shaped hole are inserted in moulding
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Of the present utility model a kind of high accuracy blanking punching structure as Figure 1-3, comprise drift 1, binder block 2 and die 3 from top to bottom, workpiece 4 and is pressed on the die by binder block between binder block and die, the center of binder block is die cavity, and drift passes the die cavity stamped workpieces.Wherein, the stamping space of the center of die formation up/down perforation recessed down.Punching structure of the present utility model also comprises push rod 5 and die plate insert 6; Push rod upwards holds out against the bottom surface of die plate insert from the bottom of stamping space; The end face of the die plate insert top tight workpiece that makes progress; The downward stamped workpieces of punching press end face enters stamping space.
Totally 2 groups of drift of the present utility model and die plate inserts.Drift of the present utility model has two, is respectively hemisection drift 1.1 and forming punching head 1.2; To punching press end face rounding off, and the punching press end face of hemisection drift is tabular surface to the hemisection drift after its punching press top external diameter slightly shrinks; Forming punching head forms bulge loop 1.2.1 behind the inner recessed certain depth of drift after its punching press top external diameter taper slightly shrinks, the inwall bottom of bulge loop more horizontal bottom center to drift extends to form horizontal ring portion 1.2.2, horizontal ring portion extends near once more giving prominence to after the bottom center of forming punching head and forms annular boss 1.2.3, and the center of boss has centre bore 1.2.4; Be provided with symmetrically irregularly-shaped hole 1.2.5 around centre bore on the horizontal ring portion; Punching press end face at forming punching head sequentially forms the stamping surface that is comprised of bulge loop 1.2.1, horizontal ring portion 1.2.2 and boss 1.2.3 certainly outside to inside; Die plate insert has two, be respectively hemisection insert 6.1 and moulding insert 6.2; The shape corresponding matching of the end face shape that hemisection is inserted and the punching press end face of hemisection drift; The shape corresponding matching of the punching press end face of the end face shape that moulding is inserted and forming punching head.
In this example, the gap between the die cavity wall of the periphery wall of drift and binder block is 5 μ m.
In this example, the gap between the perisporium of the periphery wall of die plate insert and the stamping space of die is 5 μ m.
In this example, drift is made by the powder carbide alloy of high rigidity.The drift material hardness is high, and wearability is good, can guarantee that the size of the perforate on the product that is obtained by centre bore and irregularly-shaped hole punching press after the punching press and precision are in control range.
In this example, irregularly-shaped hole has 6.
Utilize high accuracy blanking punching structure of the present utility model as follows to the operation that billot carries out punch process:
The hemisection stamping procedure is done in the first cooperation that utilizes hemisection drift and hemisection to insert at billot according to the development size of accurate Calculation, the distortional stress of material in the time of can eliminating subsequent forming on the one hand, can when doing hemisection, put down material on the other hand, also have simultaneously the effect of convenient last blanking.Also reduced simultaneously the deformation extent that blanking causes owing to have half cutting process, blanking power greatly to reduce.Then the moulding punching press is carried out in the cooperation that utilizes forming punching head and moulding to insert, and in order to prevent the appearance of work hardening, drift and die are all preferably made by carbide alloy, the flatness machining deformation of product can be controlled at minimum.When discharging, owing to pass through half cutting process, the actual coupling part of product and strip is less, and less blanking power can realize blanking, the deformation effect of product is not had substantially, thereby guarantee in the requirement of discharging process product flatness.
Above-mentionedly only several specific embodiments in the utility model are illustrated; but can not be as protection domain of the present utility model; every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should think to fall into protection domain of the present utility model.
