Abstract

The invention provides a blanking composite die which comprises an upper die seat and a lower die seat which are oppositely placed and a composite stamping device which is placed between the upper die seat and the lower die seat. The composite stamping device comprises a blanking die and a forming die. The blanking die comprises a punching stick, a punching plate, a blanking concave die and a punching convex die. The top end of the punching stick extends upwards from the upper die seat and the bottom end of the punching stick is connected with the punching plate. The blanking concave die is fixed on the lower portion of the punching plate. The punching convex die is placed inside the concave die, wherein the top end of the punching convex die is mutually and tightly compressed with the punching plate. The forming die comprises a punch-die, a discharging plate and a spring. The punch-die is placed above the lower die seat, and is in the same axial line with the punching convex die. The discharging plate connected with the lower die seat through the spring is fixed above the punch-die. The blanking die and the forming die are integrated by the blanking composite die. The blanking composite die ensures that blanking and forming working procedures are finished at a time, not only processing is simplified, but also the surface of a product has not burrs and the size accuracy of the product is improved. In addition, because a plurality of sets of composite stamping devices are set, and a plurality of belt materials or work pieces can be simultaneously processed, production efficiency is improved and cost is reduced.

Description

The stamping-out composite die

Technical field

The present invention 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 mould, tubing etc., makes it produce distortion or separate, thereby makes 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 large, therefore needs equipment (comprising mould) to possess higher automaticity and continuable machining accuracy.

Stamping-out (Blanking) is a kind of in 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 is called blanking, and its mould that uses is called blanking die (Blanking Die).After stamping-out was completed, product swept away along closed outline is separated, and waste material is stayed in blanking die.

Diel (Punch Mould) is for stamping forming mould, and in batch production 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 completing the mould of one stamping procedure in the forcing press single stroke) to complete processing; By adopting compound die (completing the mould of multi-step forming processes in the forcing press single stroke), can realize the automated production of a plurality of operations when reducing station, thereby raise the efficiency, reduce costs.

In correlation technique, adopt a plurality of single dies will be with material to be processed into product, not only technique loaded down with trivial details, affect production cost and efficient, and can cause the accumulation of error of repetition, thereby cause Product Precision decline, and the mass defect such as surface band is jagged; On the other hand, the blanking die that uses in correlation technique only carries out the processing of product of the same type for a band material, and can not process for the multi-ribbon material simultaneously, perhaps process simultaneously dissimilar product, be restricted with regard to the production efficiency that makes punching process like this.

Summary of the invention

Adopt a plurality of single dies for existing blanking die, and only carry out for a band material that the production efficiency that product machining of the same type causes is low, cost is high, and Product Precision is low, the surface is jagged defects and problem, the purpose of this invention is to provide and a kind ofly can improve Product Precision, improve surface quality, the stamping-out composite die of raising the efficiency simultaneously, reducing costs.

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

Described compound punching device comprises blanking die, shaping mould, described blanking die comprise play rod, re-pack, blanking die, piercing punch, describedly beat excellent bottom and be positioned at upper bolster, stretch out vertically upward on its top, the described upper surface that re-packs with beat the rod be connected, described blanking die is fixed on the below that re-packs, and described piercing punch is positioned at blanking die inside, its top with re-pack compression;

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

Preferred as technique scheme, the described compound punching device of respectively organizing is processed respectively dissimilar product.

Preferred as technique scheme, the described compound punching device of respectively organizing is processed respectively different band material.

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 vertically is fixed in the lower surface of upper bolster, and described guide pillar vertically is fixed 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.

Stamping-out composite die provided by the invention, blanking die, shaping mould are integrated, utilize the subtend setting on same axis of piercing punch, punch-die, realized once completing of blanking, molding procedure, not only simplify technique, raise the efficiency, and improve without burr, dimensional accuracy on the products obtained therefrom surface.On the other hand, due to many group compound punching devices can be set, therefore can process simultaneously multi-ribbon material or polytype product in mould, therefore improve the production efficiency of punching process, reduce cost.
