Abstract

The utility model relates to a compound embossing mold utensil of diphase steel, including last mould, compound die, lower mould and blank holder last mould on seted up the centre bore, the compound die be the setting of T type the centre bore in with last mould sliding fit, the lower mould be located the lower part of last mould, set up with last mould relatively last mould and lower mould between install the blank holder, the lower extreme face downward bulge of going up the mould forms the bellying, the intermediate part of the up end of lower mould forms the depressed part to sunken down. The utility model has the advantages that: when the plate is formed, the plate can be clamped, so that a high-precision product with high precision and small deformation can be obtained.

Description

Double-phase steel composite pressing die

Technical Field

The utility model relates to a compound embossing mold utensil of diphase steel belongs to the machining field.

Background

The existing die is required to be formed by adopting the die when producing thin workpieces such as diaphragm springs, brake discs, saw blades, milling cutters and the like, the die mainly comprises a female die and a male die which are matched with each other, the workpieces can be formed by punching on a press machine, and the formed workpieces are required to be taken down for heat treatment; the method has the defects that during heat treatment, workpieces are easy to deform, lose roundness, be eccentric and be unparallel, and the quality of products is influenced.

Disclosure of Invention

For overcoming the defects of the prior art, the utility model provides a compound embossing mold utensil of diphase steel, the technical scheme of the utility model is:

the double-phase steel composite pressing die comprises an upper die, a composite die, a lower die and a blank holder, wherein a central hole is formed in the upper die, the composite die is arranged in a T shape and is in sliding fit with the upper die in the central hole, the lower die is positioned at the lower part of the upper die and is arranged opposite to the upper die, the blank holder is installed between the upper die and the lower die, the lower end surface of the upper die protrudes downwards to form a protruding part, the middle part of the upper end surface of the lower die is sunken downwards to form a sunken part, the protruding part is matched with the upper half part of the sunken part, the lower end of the composite die is an arc-shaped end, and the arc-shaped end sequentially penetrates through the central hole and the hole of the blank holder and then is matched with the.

The upper die, the compound die and the lower die are all made of dual-phase steel.

Two sides of the concave part form upward bulges, and the two upward bulges are symmetrically arranged along the concave part.

The utility model has the advantages that: when the plate is formed, the plate can be clamped, so that a high-precision product with high precision and small deformation can be obtained.

Fig. 1 is a schematic view of the main structure of the present invention.

Detailed Description

The invention will be further described with reference to specific embodiments, the advantages and features of the invention will become more apparent as the description proceeds. These examples are merely illustrative and do not limit the scope of the invention in any way. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention, and that such changes and modifications are intended to be included within the scope of the invention.

Referring to fig. 1, the utility model relates to a compound embossing mold utensil of diphase steel, including last mould 2, compound 1 mould, lower mould 5 and blank holder 3 last mould 2 on seted up the centre bore, compound mould 1 be the setting of T type the centre bore in with last mould 2 sliding fit, lower mould 5 be located the lower part of last mould 2, set up with last mould 2 relatively last mould 2 and lower mould 5 between install blank holder 3, the lower extreme face downward bulge of going up mould 2 forms the bellying, the intermediate part of the up end of lower mould 5 forms depressed part 52 to sunken downwards, bellying and the first half of depressed part 52 cooperate, the lower extreme of compound mould 1 is the arc end, after this arc end passed the hole of centre bore and blank holder 3 in proper order, with the latter half of depressed part 52 cooperatees.

The upper die 2, the compound die 1 and the lower die 5 are all made of dual-phase steel.

Two sides of the concave part 52 are formed with upward protrusions 51, and the two upward protrusions 51 are symmetrically arranged along the concave part.

The utility model discloses a theory of operation is: place the panel 4 of treating processing on lower mould 5, later install the blank holder on the upper portion of panel, mould and complex film are located the upper portion of blank holder this moment, extrude panel through last mould earlier, then further extrude panel through the complex film, accomplished the shaping of panel.
