Description
Technical field
The utility model belongs to technical field, is related to a kind of mosaic finishing mold.
Background technology
Hard alloy is with the metal carbides (such as tungsten carbide, titanium carbide, ramet, niobium carbide) of high rigidity, infusibility
For main component, adhesive is done with metals such as cobalt, nickel, then a kind of superhard tool material made of being sintered through powder metallurgy process.
The room temperature hardness of usual hard alloy is up to 87~89HRA, thus the energy that has good wearability.Under identical use condition,
The service life of hard alloy is 20~50 times of punching block.Although the manufacturing cost of sintered-carbide die is 3 times or so of punching block,
But since the coefficient of expansion of hard alloy is small, elastic recoil is small, and workpiece size is stablized, while having higher precision and good thick
Rugosity, thus it is highly suitable for the mold of the high product of dimension precision requirement.However, due to its brittle influence, it is multiple in shape
It is be easy to cause fracture on mold miscellaneous, part is thin, it is very big to make it be received in the production process of complex-shaped product
Restriction.
In general, when carrying out shaping to sintered-carbide die, mold is easily broken, and is scrapped so as to cause mold.If
Material changes into die steel material, not wear-resisting, and deformation quantity is big, and product size is unstable.Finishing process is by sintered product
Cold compression is carried out in a mold, and the dimensional accuracy for improving product by being plastically deformed simultaneously improves apparent roughness.Such as Fig. 2 institutes
Show, product is lain against above former (product shape is aligned with former shape chamber), is about to directly cause in product indentation former under upper punch
It pressurizes after being contacted with bottom punch, upper punch is retracted after reaching setting pressure, is about to product on bottom punch and is deviate from from the moon.Finishing
In journey former bear product and former wall mutually rub caused by up and down shearing force and when pressurizeing radial direction pressure.Due to hard
The brittleness of alloy, when putting deviation and finishing surplus bigger than normal such as fruit product, the local thin position (as shown in Figure 1 three of mold
The key of a protrusion) it is then also easy to produce fracture, to cause mold to scrap.
The information for being disclosed in the background technology part is merely intended to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implying in any form that information composition has been existing well known to persons skilled in the art
Technology.
