Abstract

The utility model relates to an improved grinding medium structure, a body surface of the grinding medium is planted and attached with brush hair, and the outer end of the brush hair is cut into a push shape. So when the grinding medium grinds the material shell to be grinded, the brush hair can extend into the grinding dead angles of the material shell to be grinded for grinding, and the utility model can increase the quality and the texture of the grinded material and can reduce unqualified rate. The utility model has the advantages of simple structure, easy fabrication, good use effect, large grinding rage, high grinding finished product rate and low cost, and the material shell to be grinded can be provided with omnibearing grinding.

Description

Modified form grinds Jie's thing structure

The improvement that the utility model system carries out about the structure of a kind of grinding Jie thing (being commonly called as abrasive media), especially refer to a kind of can the grinding fully to desiring abrasive material, exempt and grind the dead angle generation, grind Jie's thing structure, belong to abrasive articles with a kind of modified form that reduces the product fraction defective.

At present, the product of general ejection formation is the aesthetic feeling of asking on its overall appearance, all can carry out one polish process, mainly tie up to put in the grinding drum and desire abrasive material (can be button, hair clip and the ornaments of ejection formation), and mix an amount of difformity, size grind Jie's thing in wherein, desire abrasive material by the upset order of grinding drum and in bucket, produce collision with grinding Jie thing, utilize collision mutually with burr, the clout of removing abrasive material and the effect that reaches grinding, polishing simultaneously, to improve fineness and the texture of desiring abrasive material.But above-mentioned process of lapping is often because of the grinding dead angle problem of grinding charge, causes finishing smoothly and often has and grind the many phenomenon appearance of incomplete, bad grade.So, it is more generally need all to belong to baby through the abrasive material of grinding, all need be as button, hair clip and accessory etc. through grinding to increase its brightness and color and luster, but various abrasive materials all have it to grind the dead angle, are example with the button, see also shown in Figure 1, it grinds the line perforation 11 that one of dead angle is button 1, and it is the particle of surface smoothing that known graininess is ground Jie's thing, and nature can't be bored a hole to line and 11 be ground; Second what grind the dead angle is the concave surface 12 of button 1 body, especially the corner 121 that lies in concave surface 12 is even more serious, though small-sized grinding Jie thing can enter the recess of button 1, concave surface 12 is ground, but, grind Jie's thing and can't bring into play abrasive action corner 121; Grinding three of dead angle is the decoration or the font 13 on button 1 surface, moulding was simultaneously adopted the nick mode and is showed lines and literal, when meeting this kind grinding dead angle when this kind decoration or font 13 lay in ejection formation usually, then grind Jie's thing and seemingly perform practically no function, inoperative; Also the situation with button is identical and other need abrasive material through grinding.

So,, therefore cause the grinding charge defect rate that ground through grinding drum high always because known grinding Jie thing can't grind the dead angle of grinding charge always.So, manufacturer only changes, and shape cooperates known grinding Jie thing outside the grinding charge, when outside the design grinding charge, seeing, avoid the shape of indent right angle, hole, complexity to occur as far as possible, thus, too much restriction just cause the grinding charge outward appearance stiff ordinary, do not have a variability, can't promote product quality.

In order to overcome above-mentioned shortcoming and defect, the purpose of this utility model is: provide a kind of modified form to grind Jie's thing structure, grinding Jie thing of this process improvement can carry out omnibearing grinding to each position of grinding charge, do not stay the dead angle, make by this and grind object light that Jie's thing grinds out, moist, improve the surface smoothness of grinding charge, improve the quality, reduce substandard products.

A kind of modified form of the utility model grinds Jie's thing structure, it is characterized in that: the surface system of this grinding Jie thing plants with bristle; Mat it, when grinding Jie's thing grinding charge is ground, bristle can stretch into the grindings dead angle of grinding charge and grind, with quality, the texture of raising grinding charge and reduce bad ratio defective product.

Wherein, pushing and drawing shape is cut in side system outside this bristle.

The utility model has the advantages that: simple in structure, make easily, result of use is good, the grinding scope big, can carry out omnibearing grinding to concave surface, dead angle, hole, decoration, font and the corner etc. of grinding charge product, the quality of grinding is good, yield rate is high, reduced cost, improved economic benefit.

The utlity model has following accompanying drawing:

Fig. 1 is the cutaway view of grinding charge.

Fig. 2 is the stereogram of the utility model embodiment.

Fig. 3 is the utility model embodiment view before.

Fig. 4 is the grinding state schematic diagram one of the utility model embodiment.

Fig. 5 is the grinding state schematic diagram two of the utility model embodiment.

Fig. 6 is the grinding state schematic diagram three of the utility model embodiment.

Number in the figure is as follows:

1 button, 11 lines, 12 concave surfaces of boring a hole

121 corners, 13 decorations or font 2 are ground Jie's thing

21 bristles

Now lift a preferred embodiment and cooperate diagram to be described in detail as follows: at first see also shown in Fig. 2,3, a kind of modified form of the utility model grinds Jie's thing structure, it grinds Jie's thing 2, and (present embodiment system is an example with the trapezoidal shape, grind Jie's thing 2 and can be multiple difformity, and volume is not of uniform size), in grinding on Jie's thing 2 both sides skewed surfaces is to have planted bristle 21, and bristle 21 is to be covered with on the inclined-plane, and pushing and drawing shape is cut in bristle 21 outboard ends system.

When the surface has planted bristle 21 and shape, grinding Jie thing 2 not of uniform size and grinding charge with inserting in the grinding drum, rolling and in bucket, collide, when grinding, then grind the place, grinding dead angle that Jie's thing 2 can its bristle 21 stretches into grinding charge and ground with grinding drum; Seeing also shown in Fig. 4,5,6, is that example describes with button 1, as shown in Figure 4 since bristle 21 be soft and tool flexible, the line perforation 11 of button 1 is interior grinds hole wall so can stretch into; As shown in Figure 5, because bristle 21 outboard ends systems is a pushing and drawing shape, so can stretch into concave surface 12 and the corner 121 of concave surface 12 is ground; And for example shown in Figure 6, owing to grind the surperficial tool bristle 21 of Jie's thing 2, so can directly the decoration or the font 13 on button 1 surface be ground by bristle 21; Be to be that button 1 is carried out comprehensive grinding, to solve known grinding dead angle problem.Especially side is cut into pushing and drawing shape outside the bristle 21, pushes away top-notch end place and can stretch into some apertures, concave surface corner, so that it is ground, causes to have and grinds the generation of no dead angle.

Again, the above is to be to lift a kind of for example describes in the grinding charge of process of lapping of numerous need, other various grinding charges, all can use this surperficial transplanting to have grinding Jie thing of bristle to grind such as hair clip, accessory etc., can reach does not equally have the grinding effect that grinds the dead angle.

In sum, a kind of modified form of the utility model grinds Jie's thing structure, it mainly is that grind at the grinding dead angle that utilizes the bristle of tool pushing and drawing shape to stretch into grinding charge, to improve Grinding Quality and texture, and relatively effectively reduce the defect rate of grinding charge, and,, help the progress and the exploitation of product so the appearance design of grinding charge can develop towards direction diversified, that become more meticulous because the design of the bristle of the utility model can solve the problem of grinding the dead angle.
