Abstract

The utility model provides a stamping die. The stamping die comprises an upper die holder, a lower die holder and at least three groups of convex dies and concave dies which are matched with each other on the opposite surfaces of the upper die holder and the lower die holder; the upper die holder and the lower die holder are all cake-shaped and are guided by at least three groups of guide posts and guide sleeves, which are distributed at equal intervals along the circumferential direction and are matched with each other; and anti-corrosion layers are respectively arranged on the outer surface of each convex die and the inner surface of each concave die. After adopting the technical scheme, the stamping die has the following greatest advantages that: the carrying workload of an operator is reduced, the processing period is shortened, and the work efficiency is improved; and simultaneously, in the stamping die, the anti-corrosion layers made of silicon carbide ceramic are adopted, and as the silicon carbide ceramic has good corrosion resistance, the convex dies and the concave dies are prevented from being corroded by acid, alkali, as well as corrosion powder or granular materials with strong oxidability, and the service lives of the convex dies and the concave dies are prolonged.

Description

A kind of diel

Technical field

The utility model relates to the technical field of pressing equipment, refers in particular to a kind of diel.

Background technology

Perforating die comprises upper bolster, die shoe, piercing punch, punching concave die, guide, keeper, a materials and parts and bolster at present, buffering part spring commonly used or polyurethane rubber, and the single operation perforating die of this kind once can only be accomplished a punching on the profile.If one when on different profiles, distributing the hole more, just need repeatedly punching than complicated parts.This has not only increased operating personnel's workload, and operation is many, and the process-cycle is long.Simultaneously; Existing be used for corrosivity powder such as acid, alkali or strong oxidizing property or particulate material punching press in flakes or the mould great majority of ring-type all be to adopt mould steel or carbide alloy to process; When punching press; Contact-making surface with corrosivity powder such as acid, alkali or strong oxidizing property or particulate matter is easy to corrosive wear, causes mould can't continue to use.

Summary of the invention

The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of reasonable in design reliable, corrosion resistance strong, shorten the process-cycle, reduce the diel of operating personnel's workload.

For realizing above-mentioned purpose; The technical scheme that the utility model provided is: a kind of diel; It includes upper and lower die holder and corresponding protruding, the die of working in coordination on this upper and lower die holder opposite face that be installed in; Described upper and lower die holder is patty; And lead through three groups of guide pillars and bushes that complement one another of arranging along its circumferential equidistance at least between them, this protruding, die of working in coordination has at least more than three simultaneously, and the inner surface of the outer surface of each punch and each die is provided with anti-corrosion layer.

The thickness of described anti-corrosion layer is 1～10 nanometer.

Described anti-corrosion layer is made by silicon carbide ceramics.

The utility model is after having adopted such scheme, and its great advantage is to reduce operative employee's handling workload, the shortening process-cycle, has improved operating efficiency; Simultaneously; The anti-corrosion layer that the utility model adopts silicon carbide ceramics to be made; Because the rotproofness of silicon carbide ceramics is good, can prevent to add man-hour protruding, die effectively by corrosivity powder or particulate material corrosion such as acid, alkali or strong oxidizing properties, improved service life protruding, die.

The specific embodiment

Below in conjunction with specific embodiment the utility model is described further.

Shown in accompanying drawing 1 and accompanying drawing 2; The described diel of present embodiment; It includes upper and

lower die holder

1,2 and correspondence is installed in protruding, the die 3,4 of working in coordination on these upper and

lower die holder

1,2 opposite faces, and wherein, described upper and

lower die holder

1,2 is patty; And lead with guide pin bushing 6 through three groups of guide pillars that complement one another 5 of arranging between them along its circumferential equidistance; This is worked in coordination simultaneously protruding, die 3,4 have four groups, and the inner surface of the outer surface of each punch 3 and each die 4 is provided with the anti-corrosion layer 7 that is made by silicon carbide ceramics, and the thickness of this anti-corrosion layer 7 is 1～10 nanometer.After adopting above design, because the rotproofness of silicon carbide ceramics is good, the utility model can prevent to add man-hour protruding, die effectively and corroded by corrosivity powder such as acid, alkali or strong oxidizing property or particulate material like this, has improved service life protruding, die.Simultaneously, the utility model adopts the designs protruding, die 3,4 of organizing more, can reduce operative employee's handling workload, the shortening process-cycle when making the utility model work, has improved operating efficiency, is worthy to be popularized.

The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the utility model.

Claims
