Abstract

The utility model discloses a sanded brick type abrasive belt comprising a rubber bottom layer, a fiber reinforcing layer arranged on the rubber bottom layer and used for enhancing the tensile strength of the sanded brick type abrasive belt, a rubber base layer arranged on the fiber reinforcing layer, and a great amount of sanded bricks fixed on the rubber base layer and used for realizing the purpose of grinding. The great amount of sanded bricks with certain thickness are fixed on the rubber base layer and used for grinding workpieces, so that the service life of the abrasive belt is prolonged, the cost for replacing the abrasive belt is reduced, the working efficiency of a grinder is improved, and the stability of grinding accuracy is maintained.

Description

The sanded brick formula is ground the abrasive band

Technical field

The utility model relates to a kind of grinding abrasive band, relates in particular to a kind of sanded brick formula and grinds the abrasive band.

Background technology

Grinder carries out fine gtinding to workpiece such as printed circuit board surface by the annular abrasion abrasive band of getting on is set.

Existing grinding abrasive band is an abrasive grit coating type structure, that is to say, is used in a large number realize that by adhering in cloth matter or papery basic unit the high rigidity abrasive grit of grinding effect forms the grinding abrasive band.But the abrasive grit diameter that this adhesion is got on is very little; because surface-coated abrasive material formula just, thereby cause formed grinding layer thin thickness, like this after grinding operation repeatedly; abrasive grit on the grinding layer can be worn and torn or come off gradually, and finally causing very soon can't grinding work-piece.

In other words, existing grinding abrasive band is very of short duration service life, the user must often change continually and grind the abrasive band, this has not only increased material cost, to grind the abrasive band simultaneously, to pull down and install new grinding abrasive band from grinder be work more loaded down with trivial details, consuming time, and this has reduced the operating efficiency of grinder again.In addition, frequent grinding abrasive band field-strip causes grinder precision instability simultaneously.

Thereby, be necessary to provide a kind of grinding abrasive band of improvement, so that the shortcoming that overcomes prior art increases working (machining) efficiency and precision with not enough.

The utility model content

The purpose of this utility model provides a kind of sanded brick formula and grinds the abrasive band, and its long perfomance life is changed number of times and the time cost that grinds the abrasive band thereby reduced, and has improved the operating efficiency of grinder simultaneously, and has kept the precision stability that grinds.

To achieve these goals, the utility model provides a kind of sanded brick formula to grind the abrasive band, comprises the rubber bottom, is arranged on being used on the described rubber bottom and strengthens the sanded brick formula and grind the fibrous reinforcement layer of abrasive band tensile strength, be arranged on the rubber basic unit on the described fibrous reinforcement layer and be fixed on the sanded brick that is used to realize grinding purposes in a large number in the described rubber basic unit.

Advantage of the present utility model is: be used in a large number workpiece is ground and has a certain thickness sanded brick owing to be fixed with in rubber basic unit, therefore significantly improved the service life of grinding the abrasive band, reduced and changed frequency and the time cost that grinds the abrasive band, improve the grinder operating efficiency, and kept grinding precision stability.

Below in conjunction with accompanying drawing, describe the utility model in detail by preferred embodiment.

Description of drawings

Fig. 1 is the plane structure chart that the utility model sanded brick formula is ground band.

Fig. 2 is the cross-section structure that sanded brick formula shown in Figure 1 is ground band, has showed the sandwich construction in sanded brick formula grinding abrasive band.

Fig. 3 grinds the structure chart of the grinder in abrasive band, workshop, the working site practical work process of having showed grinder for using the utility model sanded brick formula.

The specific embodiment

With reference now to accompanying drawing, the utility model is described.

Shown in Fig. 1-2, the sanded brick formula that the utility model provides is ground abrasive band 100 and is had layer structure.Particularly, described sanded brick formula grind abrasive band 100 comprise thickness be 0.5-1.5mm rubber bottom 20, be arranged on being used on the described rubber bottom 20 and strengthen the sanded brick formula and grind the fibrous reinforcement layer 30 of abrasive band 100 tensile strength, be arranged on thickness on the described fibrous reinforcement layer 30 and be the rubber basic unit 40 of 1-2mm and be fixed on the sanded brick 10 that is used to realize grinding purposes in a large number in the described rubber basic unit 40.

Especially, the thickness T of described sanded brick 10 is 3-12mm, and width W is 5-12mm, and the interval G between the adjacent sanded brick 10 then is 1-2mm.Be used in a large number workpiece grinding and thickness are the sanded brick 10 such as 3-12mm owing in rubber basic unit 40, be fixed with, therefore improved the wearability of grinding abrasive band 100, and then reduced and changed the time cost that grinds the abrasive band, because grind with 100 change that frequencies reduce greatly former thereby improved the operating efficiency of grinder, and kept grinding precision stability.

Preferably, the length that the sanded brick formula is ground abrasive band 100 is 950-2160mm, and width is 630-710mm, thereby can adapt to the grinder of all size.

With reference to figure 3, be combined with the utility model sanded brick formula and grind the grinder 200 in abrasive band 100 and comprise two groups of grinding mechanisms, every group of grinding mechanism comprise pair of turning wheels 202, the sanded brick formula on the runner 202 of being wrapped in is ground abrasive band 100 and and one of them runner 202 between auxiliary wheel 201 spaced apart.Workpiece 50 enters from the A direction in the runner 202 and the interval between the auxiliary wheel 201 of one of them grinding mechanism, and grinding operation is carried out on the surface that the rotation by runner 202 causes the sanded brick formula to grind the 100 pairs of workpiece 50 in abrasive band; Workpiece 50 enters in the runner 202 and the interval between the auxiliary wheel 201 of another grinding mechanism then, rotation by runner 202 causes the surface of the 100 pairs of workpiece 50 in sanded brick formula grinding abrasive band to carry out grinding operation once more, has finally realized the fine gtinding to workpiece 50.

Preferably, described sanded brick 10 is made by a kind of material in carborundum, boron carbide, diamond or the cubic boron nitride or the combination of different materials, thereby has improved the abrasion resistance of sanded brick 10 greatly, and then has prolonged the life-span in sanded brick formula grinding abrasive band 100.

Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
