Abstract

The invention discloses a hard alloy die which comprises a base, a hard alloy core, a hard alloy punch and a receding device. The hard alloy core is placed in the base. A buffering part is arranged at the end in the base. The hard alloy core abuts against the buffering part. An opening of the base is a trapezoid-shaped guiding opening. Locating holes are formed in the two side walls of the base. Fixing holes matched with the locating holes are formed in the corresponding positions of the hard alloy core. Mounting to the locating holes is carried out through locating bolts, and fastening with the fixing holes is carried out. The buffering part is arranged in the base, the impact force of the hard alloy punch can be effectively lowered, a die core is located through the locating bolts, stress on the die core is lowered, and the die core cannot be bent easily.

Description

A kind of sintered-carbide die
Technical field
The invention discloses a kind of sintered-carbide die, belong to five metals processing technique field.
Background technology
Sintered-carbide die has the advantages such as high rigidity, highly corrosion resistant, the coefficient of expansion be little, conventional sintered carbide die has cold heading die, cold-punching mould, wire drawing die, hexagonal moulds etc., in existing punching machine mold, mold cores is arranged in die matrix, employing bolt is fixed, but adopts bolt too to concentrate to make to produce bending in mold cores punching course, easily for a long time cause major injury even can not reuse to core.
Summary of the invention
The object of the present invention is to provide a kind of stability high, the sintered-carbide die of the improvement that product compacting precision is high.
For achieving the above object, the technical solution adopted in the present invention is as follows:
A kind of sintered-carbide die, comprise pedestal, carbide alloy core, hard alloy punch head and device of giving up the throne, described carbide alloy core is positioned at pedestal, described pedestal inner end is provided with a buffer part, carbide alloy core and buffer part offset, the opening of described pedestal is targeting port, the end of described carbide alloy core is provided with hard alloy punch head, the both sides sidewall of described pedestal offers locating hole, the fixing hole suitable with locating hole is offered in the relevant position of carbide alloy core, bolt is adopted to be installed on locating hole and to be fastened with fixing hole, described device of giving up the throne is arranged on the lower end of carbide alloy core, device of giving up the throne is made up of spring part and back pieces plate.
The contact surface that aforesaid carbide alloy core and buffer part offset is arc convex.
Aforesaid targeting port is trapezoidal.
The end face of aforesaid hard alloy punch head is hemisphere face.
Aforesaid locating hole is a row or two rows.
There are 2 or 3 in aforesaid every registration hole.
The present invention arranges buffer part in pedestal, effectively can reduce the impulsive force of hard alloy punch head, and the present invention is fixed mold cores by multiple bolt, alleviates the stressed of mold cores, makes it not easily bend.
Accompanying drawing explanation
Fig. 1 is the structural representation of sintered-carbide die of the present invention.
Detailed description of the invention
Now with detailed description of the invention, the present invention is described in further detail by reference to the accompanying drawings.
As shown in Figure 1, sintered-carbide die of the present invention comprises pedestal 9, carbide alloy core 3, hard alloy punch head 4 and device of giving up the throne, wherein, carbide alloy core 3 is positioned at pedestal 9, be provided with a buffer part 1 at pedestal 9 inner end, carbide alloy core 3 and buffer part 1 offset, and both contact surfaces are arc convex 2, by arranging arc convex, the impulsive force of hard alloy punch head effectively can be slowed down.
The opening of pedestal 9 is targeting port 7, and this targeting port 7 is trapezoidal design, and the top size of targeting port 7 and the width of carbide alloy core match, and the following of targeting port is slightly longer than top, is convenient to carbide alloy core and embeds in pedestal.
Be provided with hard alloy punch head 4 in the end of carbide alloy core 3, the end face of hard alloy punch head 4 is hemisphere face.
Device of giving up the throne is arranged on the lower end of carbide alloy core 3, and device of giving up the throne is made up of spring part 6 and back pieces plate 5.
The both sides sidewall of pedestal 9 offers locating hole 8, offers the fixing hole suitable with locating hole in the relevant position of carbide alloy core, adopt bolt be installed on locating hole and be fastened with fixing hole.
Preferably, locating hole can be a row, also can be two rows.
Preferably, can there be 2 or 3 in every registration hole.
