Ceramic tile grinding tool with irony bottom is made of bistrique, metal dish and nut three parts, and metal dish uses mechanical processing side Method manufactures, and 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 manufactures, and after machining, 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, ensures the angle of the two It is 90 degree, and will not loosen to spend, in order to avoid follow-up 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, it is suppressed using forcing press After heat or be directly entered sintering machine and be sintered, have gap digit 123 on irony bottom, be to be put into the stone that thickness is 1 ~ 3mm In ink sheet to graphite mo(u)ld, after the completion of sintering, graphite flake is taken out, forms gap digit.

After sintering is completed, cooling extrudes bistrique after cooling using forcing press,

Screw rod 11 is inserted into screw hole 21, is locked using nut, complete Product Assembly, product grind can not in use, Nut is unscrewed, takes out bistrique, new bistrique is installed.

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 into circumference array Cloth, the circumference array refer to that all bistriques equidistantly distribute on array circle, and array justifies the outer circle for referring to metal dish,

Irony bottom is sector flat plate, thickness >=3mm, and the inner circle of the circular diameter where fan-shaped Inner arc=recessed position 25 is straight There is the recessed position of 0.5 ~ 1mm at diameter, the outer diameter of circular diameter=metal dish where fan-shaped external arc, irony bottom, are recessed position and limiting Side 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, design During mold, all roll flute shape sizes need consistent, copper sheet or identical, the circle where the Inner arc of roll flute of thickness of scale needs The interior circular diameter of diameter=recessed position 23, the outer diameter of circular diameter=metal dish where the external arc of roll flute,

The sintering mold of bistrique, the sintering mold of bistrique are made of alloy steel membrane, gray cast iron mould and shaping mould, bed die, into Pattern 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 base, bottom Side 3 ~ 7mm of thickness, shaping mould have screw hole 71 to be used for across screw rod 11, why separate base and bed die, be it is conveniently stripped, by 45 ~ 55mm is grown in screw rod, base also serves as bed die, and press pressure is huge during demoulding, moreover, shaping mould thickness is too thick, due to only Can first use, expense is higher, and shaping mould die wall can reduce cost, gray cast iron mould is outermost outside shaping mould in 3 ~ 7mm Side is alloy steel dies, and alloy steel dies material is high-temperature alloy steel, and material of soffit form is graphite, is had on bed die and 11 position pair of screw rod The screw hole 91 answered, screw rod hole depth are more than spiro rod length, in this way, screw rod will not be bent during sintering, after sintering, due to gray cast iron Characteristic with pyrocondensation cold expanding, can keep that product is indeformable, and still, strength of gray cast iron is low, high temperature and pressure in cooling procedure Burn failure is be easy to cause, therefore, using high-temperature alloy steel on the outside of gray cast iron mould, prevents gray cast iron wear bad, and bistrique Shaping mould use graphite, be on the one hand graphite can high temperature resistant, be on the other hand that graphite is soft, after cooling, held using forcing press Easily bistrique and shaping mould are detached.

Extruding dies are the molds for taking out bistrique from sintering mold, and extruding dies are the lower dies of forcing press, and extruding mouth is Sector, it is fan-shaped wider 1 ~ 2mm than the inside and outside circular arc at irony bottom, in this way, will not be by the resistance of mold body, in pressure when extruding Under the action of machine, the base of shaping mould and shaping mould separation, then, bistrique is forced out, and base from bistrique is taken out, 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 More than weld strength, and sintering process flow is simple, low to the technology requirement 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 to pass through lathe car 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 an experienced operator about welds 80 grinding tools in 8 hours, if screw rod Tightening technique tightens calculating, about at 150 by 18 nuts of a disk.
