Ceramic tile grinding tool with irony bottom is made of bistrique, metal dish and nut three parts, and metal dish uses machining side Method manufacture, compared with existing metal dish, only more screw hole 21 and position-limited edge 22, screw hole 21 and position-limited edges 22 are all It can be manufactured using machining process, that is to say, that the ceramic tile grinding tool with irony bottom is compatible existing metal dish, this Be conducive to save material, the auger shell rod aperture on existing metal dish, turning is recessed position, and edge reserves part not turning, that is, is limited Position side,

And the processing of nut is common knowledge, is no longer described in detail.

Bistrique is made of four parts, i.e., screw rod 11, irony bottom 12, roll flute 1 and iron plate 13 form, and irony bottom and screw rod use Machining process manufacture, after processing is completed, there is threaded hole 121 at irony bottom, and screw rod 11 is locked into threaded hole 121, it should be noted that , why is locked using threaded hole, it is adjacent to using the datum level of screw rod and the datum level at irony bottom, guarantees the angle of the two Degree is 90 degree, and will not be loosened, in order to avoid subsequent bad processing, therefore, screw rod needs full thread, by screw rod be locked into irony bottom it Afterwards, graphite mo(u)ld is put it into, iron plate is placed into notch, is then placed in the alloyed powder stirred evenly, suppress it using press machine After heat or be directly entered sintering machine and be sintered, have gap digit 123 on irony bottom, be the stone being put into a thickness of 1 ~ 3mm Ink sheet is into graphite mo(u)ld, and after the completion of sintering, graphite flake is taken out, and forms gap digit.

It is cooling after sintering is completed, it is cooling to extrude bistrique using press machine later,

Screw rod 11 is inserted into screw hole 21, is locked using nut, Product Assembly is completed, product is ground when not being available, by spiral shell Cap is unscrewed, and takes out bistrique, installs new bistrique.

The position and quantity of its threaded hole 121 of irony bottom and the screw hole 21 of a bistrique installation position be it is corresponding, one Metal dish has N number of bistrique installation position, correspondingly, installing N number of bistrique, N >=2, in arrangement, all bistriques are arranged at circumference array Cloth, the circumference array refer to that all bistriques equidistantly distribute on array circle, and array circle refers to the outer circle of metal dish,

Irony bottom is sector flat plate, thickness >=3mm, the interior circular diameter in the circular diameter where fan-shaped Inner arc=recessed position 25, fan There is the recessed position of 0.5 ~ 1mm at circular diameter=metal dish outer diameter where the external arc of shape, irony bottom, are recessed position and position-limited edge 22 Be it is corresponding,

Roll flute is uniformly arranged on irony bottom, is separated between roll flute and roll flute using iron plate, iron plate 1 ~ 2mm of thickness, and mold is designed When, all roll flute shape sizes need consistent, copper sheet or identical, the circular diameter where the Inner arc of roll flute of thickness of scale needs The interior circular diameter of=recessed position 23, circular diameter=metal dish outer diameter where the external arc of roll flute,

The sintering mold of the sintering mold of bistrique, bistrique is made of alloy steel membrane, gray cast iron mould and shaping mould, bed die, shaping mould It is innermost mold, is the shape of bistrique on the inside of shaping mould, the material of shaping mould is graphite, and shaping mould has bottom edge, bottom edge thickness 3 ~ 7mm, shaping mould have screw hole 71 be used to across screw rod 11, why bottom edge and bed die are separated, be it is conveniently stripped, due to spiral shell Bar grows 45 ~ 55mm, and bottom edge also serves as bed die, and press pressure is huge when demoulding, moreover, shaping mould thickness is too thick, due to can only one Secondary use, expense is higher, and shaping mould die wall can reduce cost in 3 ~ 7mm, and outside shaping mould, outermost is gray cast iron mould Alloy steel dies, alloy steel dies material are high-temperature alloy steels, and material of soffit form is graphite, are had on bed die corresponding with 11 position of screw rod Screw hole 91, screw rod hole depth are greater than spiro rod length, in this way, screw rod will not be bent when sintering, after sintering, since gray cast iron has The characteristic of pyrocondensation cold expanding, is able to maintain that product is indeformable, and still, strength of gray cast iron is low in cooling procedure, and high temperature and pressure is easy Burn failure is caused, therefore, high-temperature alloy steel is used on the outside of gray cast iron mould, prevents gray cast iron wear bad, and the molding of bistrique Mould uses graphite, be on the one hand graphite can high temperature resistant, be on the other hand that graphite is soft, after cooling, utilizing press machine to be easy will Bistrique and shaping mould separation.

Extruding dies are the molds for taking out bistrique from sintering mold, and extruding dies are the lower dies of press machine, and extruding mouth is Sector, it is fan-shaped 1 ~ 2mm wider than the inside and outside circular arc at irony bottom, it not will receive the resistance of mold body when in this way, extruding, in pressure Under the action of machine, the bottom edge of shaping mould and shaping mould separation, then, bistrique is forced out, and bottom edge is taken out from bistrique, obtains finished product Bistrique.

Compare two kinds of processing technologys it finds that, compared to welding, the bonding strength of its irony bottom of sintering process and bistrique is remote Greater than weld strength, and sintering process process is simple, low to the technical requirements of worker, also more environmentally-friendly, does not have in operating process The toxic smoke mist for having welding to generate, does not use expensive silver-colored zinc weld tabs yet, and the service life of metal dish also improves, although Welding procedure is also to reuse metal dish, and still, after roll flute is removed, welding portion can remain welding slag, need through lathe vehicle Recessed position is cut, in this way, it is more and more thinner to will result in metal dish, cannot just be used to a certain extent, pickling washes, dries this A little techniques are also time saving like that not as good as screw rod tightening technique, and one is about welded 80 grinding tools in experienced operator 8 hours, if it is screw rod Tightening technique tightens calculating by 18 nuts of a disk, about at 150.
