Description
Technical field
The present invention relates to a kind of diamond grinding grinding tool, the invention still further relates to the manufacturing installation of this diamond grinding grinding tool.
Background technology
Machine components are carried out the specification requirement that grinding has become a kind of routine, and present widely used grinding grinding tool mainly adopts manufacturings such as SiC, corundum.SiC, corundum grinding grinding tool wear no resistance, and service life is short, and very fast, the poor dimensional stability of autophage causes size, shape and the precision of part to be processed to change in Grinding Process, needs often SiC, corundum grinding grinding tool to be revised.Simultaneously, SiC, corundum grinding grinding tool have hard, crisp characteristics, and obdurability is poor, and particularly sudden breaking in use appears in some special-shaped emery wheels easily, causes security incident because of rotating at a high speed.When being used for processing the part of high-abrasive material preparation in enormous quantities, the problems referred to above of SiC, corundum grinding grinding tool are particularly outstanding, have a strong impact on the quality and the performance of part to be processed, and production efficiency is low, and potential safety hazard is outstanding.
For example, what use on the brake block production line at present is the grinding tool that a kind of SiC makes, and is a kind of friction material with better anti-wear performance owing to what prepare the brake block employing, the wretched insufficiency in service life of SiC grinding tool, generally only 6000～8000 brake blocks of grinding just need to change, and waste time and energy; On the other hand, because of equipment for grinding adds the SiC grinding tool protective cover that breaks, wear condition that can't direct-on-line Real Time Observation grinding tool, just passive replacing when grinding tool breaks under because of the less footpath outward force effect of excessively using, be ground processing parts, the grinding tool of rotation breaks and easily causes security incident at a high speed, easily causes product rejection on the other hand.Because the wretched insufficiency in service life of SiC grinding tool makes its replacement cycle short (general 3～4 days), wastes time and energy, and increases the product percent defective, potential safety hazard can't be eliminated.
For the problems referred to above, except the protection that tightens security, regularly shutdown inspection, change the grinding tool in advance, do not have better solution at present.
The present invention proposes a kind of diamond grinding grinding tool and manufacturing installation thereof, can solve effectively that the grinding grinding tool of manufacturings such as present employing SiC, corundum exists wear no resistance, service life is short and obdurability is poor, occur sudden problem such as break easily, improve security, production efficiency and product quality and the performance of producing, the rate of reducing the number of rejects and seconds also can be processing enterprise simultaneously and saves cost, increases economic efficiency.
Summary of the invention
First technical problem that the present invention will solve provides that a kind of grinding performance excellence, wearability are good, long service life and have high-strength tenacity, be not easy to occur the sudden diamond grinding grinding tool that breaks.
Second technical problem that the present invention will solve provides a kind of raising diamond grinding grinding tool and makes efficient, reduces the device of the manufacturing diamond grinding grinding tool of manufacturing cost.
In order to solve above-mentioned first technical problem, diamond grinding grinding tool provided by the invention, comprise the cup-shaped cylindric matrix of hollow, the height of the cup-shaped cylindric matrix of described hollow/diameter ratio is 1: 3～1: 5, the outer surface of the cup-shaped cylindric matrix of described hollow is provided with one deck and the cup-shaped cylindric matrix of described hollow become the integral body of metallurgical binding through HIP sintering diamond dust carcass, described diamond dust carcass is even, fine and close, and the cup-shaped cylindric matrix adopting structural carbon steel of described hollow is made.
Adopt the diamond grinding grinding tool of technique scheme, the cup-shaped cylindric matrix of the hollow of structural carbon steel manufacturing has high obdurability, even the abrasive material of grinding tool has been consumed, can not break yet, this can prevent effectively that grinding tool from sudden breaking in use being taken place; Diamond, metal dust bonding agent are realized complete metallurgical binding by HIP sintering with the cup-shaped cylindric carbon structure steel matrix of hollow, can prevent effectively that the diamond carcass from use coming off, breaking; Utilize adamantine high rigidity in the diamond carcass, high-wearing feature to carry out grinding, can effectively improve grinding performance, wearability and the service life of grinding tool.Because the significant difference of diamond dust carcass and the cup-shaped cylindric matrix wearability of hollow, can be when the grinding performance reduction appears in grinding tool, the continuation use and the replacing problem of timely online definite grinding tool, avoided using the potential safety hazard that causes because of excessive, and because of changing the phenomenon of wasting in advance.
In order to solve above-mentioned second technical problem, the device of manufacturing diamond grinding grinding tool provided by the invention, by outer die casing with effect of contraction, base with support and positioning action, upper mold core and pressure ring are formed, the inner chamber of described outer die casing is cylindrical, inner chamber bottom at described outer die casing is provided with base, in described outer die casing, be provided with the upper mold core that is in above the described base, described base is provided with the positive stop lug boss that the cup-shaped cylindric matrix of described hollow is positioned, the cup-shaped cylindric matrix of hollow is installed between described base and the described upper mold core, the cup-shaped cylindric matrix of described hollow is located described upper mold core, at described outer die casing, base, form an annular space that is used to fill diamond dust carcass raw material between the assembly that the cup-shaped cylindric matrix of upper mold core and hollow constitutes, described pressure ring is enclosed within on the described upper mold core and is pressed in the described annular space.
Described outer die casing, base, upper mold core and pressure ring adopt the graphite material manufacturing.
Adopt the device of the manufacturing diamond grinding grinding tool of technique scheme, wherein the inner chamber of outer die casing is cylindrical, base designs positive stop lug boss, the cup-shaped cylindric matrix of hollow is positioned, and upper mold core is positioned by the cup-shaped cylindric matrix of hollow, the annular space that constitutes by outer die casing and the cup-shaped cylindric matrix of base, upper mold core and hollow, be used to fill diamond carcass and carcass thermal sintering, and pressure ring led, sintering pressure imposes on the diamond dust carcass by pressure ring.
The using method of the manufacturing installation of a kind of diamond grinding grinding tool provided by the invention, with outer die casing, base, the cup-shaped cylindric matrix of hollow and upper mold core assembling, the diamond carcass of the mixing that will determine the as calculated annular space that the cup-shaped cylindric matrix of outer die casing and base, upper mold core and hollow constitutes of packing into then, and it is uniformly distributed in wherein, pressure ring is installed then.At last, it is integral sintered that the integral body that assembles is placed on the intermediate frequency hot pressed sintering machine sintering process of setting by establishment, makes the diamond abrasive tool that carcass height, density and performance meet design requirement.
