Description
Technical field
The utility model is related to grinding tool to manufacture field, more particularly to abrasive tool moulding mould.
Background technology
Superhard material grinding tool is generally made up of metallic matrix and abrasive material.Abrasive material is the working lining of superhard material grinding tool,
Its preparation technology directly affects the performance of product.The preparation of abrasive material is generally first by super hard abrasive, bonding agent and filler etc.
Powder is well mixed in the presence of wetting agent, and powder then is shaped into design under forming machine effect using particular manufacturing craft
Shape, eventually passes follow-up special procedure treatment and forms abrasive material.In the process, molding procedure for abrasive material preparation extremely
Close important, directly affect the geomery of abrasive material, and the size shape of abrasive material is ensured by particular manufacturing craft.Therefore, mould
Have has important effect to the moulding process of superhard material grinding tool abrasive material.
The mould of traditional superhard material grinding tool typically uses metal material, and structure is as depicted in figs. 1 and 2：
1- mould seaming chucks：It is slidably matched with die sleeve 2, press pressure is from top to bottom transferred to powder 3.
2- die sleeves：Middle part is provided with through hole, while being slidably matched with mould seaming chuck 1, mould push-down head 2, forms closing
Cavity, powder 3 is placed in cavity.
3- powders：It is made up of the mixing such as super hard abrasive, bonding agent and filler, is fettered in the upper and lower ram pressures of mould and die sleeve
The lower shaping of effect.
4- mould push-down heads：Press pressure is transferred to powder 3 from the bottom to top.
When mould is used, mould push-down head 4 is embedded in die sleeve 2, then powder 3 is placed in die sleeve 2, mould seaming chuck
1 insertion die sleeve 2, the mould that will finally assemble is placed on moulding press workbench and is pressed.
Due to containing super hard abrasive and filler in powder, the upper push-down head and die sleeve hardness of metal material are far below abrasive material
Hardness, die wear speed, service life is shorter.Upper push-down head after abrasion diminishes with die sleeve matching part size, mould
Set corresponding site becomes large-sized, and the mould for assembling, powder material leakage is serious, using the compressing abrasive material of dull die not
But dimension overproof, compact density changes, and there is side phenomenon, the performance influence on product is larger.In addition by
Very fast in the rate of wear, die life is shorter, causes the die cost of product and increases.
