Description
Technical field
The utility model relates to the shaping production and processing mould of hot pressing abrasive tool blank, specifically a kind of grinding stone heat pressing and molding mold.
Background technology
Because the special grinding stone of hot-forming steel rail grinding (emery wheel) is that grand master pattern is shaping, grinding stone hardness is high, and processing grinding stone working face is very difficult, and even plain grinding is not processed.The object of processing grinding stone is put the first edge on a knife or a pair of scissors be convenient to grinding stone polishing operation; Otherwise grinding stone cannot be installed and used.
The shaping mould of grinding stone according to the designing requirement manufacture to mould, must comprise when designing:
1. mould structure should meet grinding stone shape of product and size;
2. mould structure is convenient to assembly and disassembly;
3. mould will have enough packed heights, i.e. H=Kh+B, H=H
1+ H
2; Wherein, H is the height (mm) of die sleeve (plug), H
1for Upper Die-sleeve height (mm), H
2for lower die-sleeve height (mm), K is die mould coefficient (compression ratio), and h is the shaping height (thick) degree (mm) of grinding stone, and B is the thickness (mm) of upper mould plate and lower bolster,
k=1.4 ~ 2.0, cover half K=1;
4. mould and molding mass contact surface will have the roughness of setting, hardness, toughness and wearability.
Because existing grinding stone moulding process all adopts cold moudling, cold moudling all adopts the high Design of Dies of COEFFICIENT K=2, could meet production technology forming requirements.Therefore, mould is typically designed to single structure.And for the grinding stone product needing hot press forming technology to produce, according to the mould that above-mentioned designing requirement manufactures, grinding set height is more than 2 times of grinding stone height, hot pressing die thermal energy conduction distance is large, waste heat energy, and the hot-forming mould that needs is many, usual need of production 8 ~ 12 mold participates in keeping output simultaneously.Because Making mold needs a large amount of forging steel billets to process die sleeve, core (type) rod, this just causes hot pressing product product cost to strengthen.
Utility model content
