Abstract
The utility model relates to a mould sleeve used for covering and inlaying an abrasive wheel in the forming process of the abrasive wheel. The utility model is characterized in that an internal sleeve and an external sleeve are matched with each other to integrity through interference fit; the external sleeve can be permanently used; when the utility model is seriously worn out, the utility model can be continuously used only by replacing the internal sleeve, and the replacement is convenient; not only raw materials are saved, but also processing cost is reduced, processing cycle is shortened, and waste caused by the entire damage of the mould of the abrasive wheel is avoided; after being processed by heat treatment, the hardness of the internal sleeve is higher than the hardness of an original mould sleeve, and the service life of the utility model is extended; at the same time, the quality of the product of the abrasive wheel is improved.
Description
The utility model relates to the die sleeve of the mould that is used for abrasive wheel forming.
The mould of abrasive wheel forming comprises at the bottom of die sleeve, the upper and lower mould, and plug for die sleeve, is an overall structure mostly, after the die sleeve wearing and tearing its diameter is increased, and can only scrap, and causes great waste.This overall structure, the manufacturing cost height, the process-cycle is long.The technology report is arranged, with the interior round reaming of waste and old die sleeve, pouring into a mould high chromium white iron or nickel chromium triangle white iron on the casting machine again, back internally circle is worked into given size.This mode has reduced manufacturing cost, but wearing and tearing again and again, cast repeatedly is also inconvenient, uses to have limitation.
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of Abrasive wheel mould with internal cover with double-layer structure is provided, and reduces processing and use cost, and it is convenient to change.
Abrasive wheel mould with internal cover of the present utility model, its major technique characteristics are to be combined into one mechanically by overcoat and interior cover double-layer structure.
Above-mentioned overcoat and interior cover are that interference fit is fitted in together, and the magnitude of interference is: fit dimension be interior cover than overcoat diameter big by 2.5～3 ‰.
Cover thickness is 2.5～4 millimeters high-carbon alloy steel in above-mentioned, can determine according to wear extent.Overcoat can be that original material is made, and also can be to utilize the die sleeve of grinding wheel of scrapping to obtain after reaming.
During manufacturing, inside and outside cover is fitted in together by the magnitude of interference, and internally circle carries out machined, until the size of Standard Module.
Fig. 1 is a structural representation of the present utility model;
Among the figure: cover in 1 overcoat 2
Advantage of the present utility model:
1, overcoat can forever use, and when the die sleeve serious wear, only needs to change inner sleeve and can continue to use, and it is convenient to change, not only Save raw material, and reduced processing cost, shortened the process-cycle, avoided all scrapping the waste that brings.
2, the inner sleeve former die sleeve hardness of hardness ratio height has after heat treatment improved the die sleeve life-span, has improved simultaneously the product matter of emery wheel Amount.
3, after die sleeve adopted structure of the present utility model, other required still same prior art.
Claims (4)
1, a kind of Abrasive wheel mould with internal cover is characterized in that being combined into one mechanically by overcoat and interior cover double-layer structure.
2, die sleeve according to claim 1 is characterised in that overcoat and interior cover are interference fit.
3, die sleeve according to claim 2 is characterised in that the magnitude of interference is: fit dimension be interior cover than overcoat diameter big by 2.5～3 ‰.
4, according to claim 1,2,3 described die sleeves, cover thickness is 2.5～4 millimeters in being characterised in that.
