Description

The stamping-out composite die

Technical field

The utility model relates to the Stamping Die Technology field, particularly a kind of stamping-out composite die.

Background technology

Punch forming process (Punch Forming Process) is to apply external force by forcing press to being fixed on sheet material in the mould, tubing etc., makes it produce distortion or separates, thereby make the method for processing forming of the workpiece of required form, size and performance.Punch forming process has the advantages that speed is fast, batch is big, therefore needs equipment (comprising mould) to possess higher automaticity and continuable machining accuracy.

Stamping-out (Blanking) is a kind of in the punch forming, is the stamping procedure that a part and another part with sheet material are separated from each other along the sealing lines, and it utilizes the cutting edge of punch die to make sheet material produce detrusion and realize separating along outline line.The stamping-out that obtains the endoporus of definite shape, size is called punching; The stamping-out that acquisition has the product of certain appearance profile, size then is called blanking, and its employed mould is called blanking die (Blanking Die).After stamping-out was finished, product swept away along closed outline is separated, and waste material is stayed in the blanking die.

Diel (Punch Mould) is to be used for stamping forming mould, and in batch process at a high speed, the design of diel can have a direct impact with quality and the production efficiency made stamping parts.Diel has stronger specificity, for baroque part, often needs number cover single die (only finishing the mould of one stamping procedure in the forcing press single stroke) to finish processing; By adopting compound die (finishing the mould of multi-step forming processes in the forcing press single stroke), can when reducing station, realize the automated production of a plurality of operations, thereby raise the efficiency, reduce cost.

In the correlation technique, adopt a plurality of single dies will be with material to be processed into product, not only technology loaded down with trivial details, influence production cost and efficient, and can cause the accumulation of error of repetition, thereby cause the product precise decreasing, and the surface has mass defects such as burr; On the other hand, employed blanking die only carries out the processing of product of the same type at a band material in the correlation technique, and can not process at the multi-ribbon material simultaneously, perhaps process dissimilar products simultaneously, be restricted with regard to the production efficiency that makes punching process like this.

The utility model content

Adopt a plurality of single dies at existing blanking die, and only carry out that the production efficiency that product of the same type processing caused is low, cost is high at a band material, and the product precision is low, the surface is jagged above-mentioned defective and problem, the purpose of this utility model provides a kind ofly can improve the product precision, improve surface quality, the stamping-out composite die of raising the efficiency simultaneously, reducing cost.

In order to achieve the above object, the utility model provides following technical scheme: a kind of stamping-out composite die, it is characterized in that, and comprise the upper bolster and the die shoe of relative installation, and be installed in the compound decompressor between upper bolster and the die shoe;

Preferred as technique scheme, the quantity of described compound decompressor is no less than two groups.

Preferred as technique scheme describedly respectively organized compound decompressor and processes dissimilar products respectively.

Preferred as technique scheme describedly respectively organized compound decompressor and processes different band material respectively.

Preferred as technique scheme, described blanking die also comprises push rod, pushing block, and the top of described push rod is connected on the lower surface that re-packs, and its bottom is connected with pushing block, and the cross section of described pushing block is annular, it is arranged between the sword wall of piercing punch and blanking die.

Preferred as technique scheme also comprises die shank, and the bottom of described die shank is positioned at upper bolster, and the upper surface that upper bolster is passed on its top stretches out vertically upward, and ring is located at beats the rod outside.

Preferred as technique scheme also comprises guide pin bushing, and the guide pillar that is complementary with it, and described guide pin bushing vertical fixing is in the lower surface of upper bolster, and described guide pillar vertical fixing is in the upper surface of die shoe.

Preferred as technique scheme, the quantity of described guide pillar is two, it is fixed on the upper surface both sides of die shoe symmetrically.

The stamping-out composite die that the utility model provides, blanking die, shaping mould are integrated, utilize the subtend setting on same axis of piercing punch, punch-die, realized once finishing of blanking, molding procedure, not only simplify technology, raise the efficiency, and the no burr in products obtained therefrom surface, dimensional accuracy raising.On the other hand,, therefore can process multi-ribbon material or polytype product simultaneously in mould, therefore improve the production efficiency of punching process, reduce cost because the compound decompressor of many groups can be set.
