Abstract
The invention discloses a hard alloy die, which comprises an upper die, a lower die and a plurality of die cores, wherein the upper die and the lower die can be oppositely stretched; each die core is composed of an upper molding cavity in the upper die, a necking-down cavity in the lower die and a lower molding cavity; guide posts are arranged on the positions of the upper die, on two sides of each mold core; and guide grooves are formed in the corresponding upper die. By the plurality of die cores, the drawing efficiency can be improved; through cooperation of the guide posts and the guide grooves, the upper die and the lower die can be stretched along a straight line; the stretching accuracy is improved; in addition, a layer of hard alloy layer is arranged in the die made of a chrome steel material, so that the cost of the die is reduced; and the service life of the die is relatively long.
Description
Technical field
The invention discloses a kind of sintered-carbide die, belong to five metals processing technique field.
Background technology
Traditional carbide alloy drawing mould only has a station, and each drawing can only complete the drawing of a product, which results in production efficiency low, and staff labor intensity is large, and production cost occupies high little.And in drawing process, due to mold integral machine-shaping, it, by under the huge frictional force effect being drawn into type, easily causes wearing and tearing, make the mold use life-span shorter, and Hardmetal materials cost is very high, is unfavorable for applying of market.Therefore, a kind of structure improved sintered-carbide die is urgently needed.
Summary of the invention
The object of the present invention is to provide a kind of use cost low, the much higher station sintered-carbide die of production efficiency.
For achieving the above object, the technical solution used in the present invention is as follows:
Sintered-carbide die, comprise patrix, counterdie and several core rods, described upper die and lower die can stretch relatively, described core rod, by the upper forming cavity being positioned at patrix, is positioned at the necking down chamber of counterdie, compacted under chamber and forms, the both sides of described each core rod, be positioned at patrix position and be provided with guide post, corresponding counterdie is provided with guiding groove.
Aforesaid upper die and lower die all adopt chromium steel material to make.
Aforesaid core rod is 3 to 5.
Aforesaid necking down chamber is trapezoidal, and top is consistent with the bore of upper forming cavity, consistent with the bore in compacted under chamber below.
The aforesaid inner surface at upper die and lower die establishes one deck hard alloy layer, described hard alloy layer and upper die and lower die interference fit.
Aforesaid carbide alloy layer thickness is 0.5mm.
Sintered-carbide die of the present invention is provided with multistation, and a drawing process just can realize the drawing of multiple workpiece, significantly reduces the labour intensity of employee, improves production efficiency.The present invention by arranging one deck hard alloy layer in the mould of chromium steel material in addition, thus reduce the cost of mould, and make the mold use life-span longer.
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 patrix 7, counterdie 5 and several core rods.Wherein patrix 7 and counterdie 5 all adopt chromium steel material to make, and patrix 7 can stretch relatively with counterdie 5.Core rod is by the upper forming cavity 1 being positioned at patrix 7, and the necking down chamber 3, the compacted under chamber 4 that are positioned at counterdie 5 are formed.The core rod of counterdie comprises necking down chamber and compacted under chamber, and wherein, necking down chamber 3 is trapezoidal, and top is consistent with the bore of upper forming cavity 1, consistent with the bore in compacted under chamber 4 below, adopts necking down chamber that the workpiece be stretched can be made to be stretched gradually, plays the effect of buffering.
Core rod as required, can be 3 to 5.
Preferably, in the both sides of each core rod, be positioned at patrix position and be provided with guide post 6, corresponding counterdie is provided with guiding groove, by the cooperation of guide post 6 and guiding groove, patrix 7 and counterdie 5 can be made linearly to stretch.
Preferably, establish one deck hard alloy layer 2 at the inner surface of patrix 7, counterdie 5, this hard alloy layer 2 and upper die and lower die interference fit, carbide alloy can improve the anti-wear performance of mould, increases the service life.
Preferably, hard alloy layer 2 thickness is 0.5mm.
