Abstract

The utility model discloses the structure of a thin-type grooving abrasive wheel. A plurality of wide and deep exterior margin grooves are staggerly arranged at two end faces of the abrasive wheel, and the grooves are gradually transited along the central direction. The geometric size of the groove is basically null at the scrap position of the diameter of the grinding wheel when the groove is shallow and narrow. Plane screw strengthening edges with multi-head can also be arranged on the grooves. The abrasive wheel with definite thickness can be formed by simple superposition and bonding. The practical requirements of strength, grinding, use, etc. of the thin-type grooving abrasive wheel can be satisfied, and the manufacturing process is simple.

Description

Thin-type grooving abrasive wheel

The utility model relates to the manufacturing technology field of slim emery wheel, relates to fluting thin type emery wheel specifically.

Because thin type emery wheel (one-tenth-value thickness 1/10 is far smaller than diameter), the rupture strength that it is original, revolving strength is just lower, and the slim emery wheel of some specification need be in middling speed, at a high speed, middle load, high-load condition uses down, fluting is very difficult thereon, be at the netted groove of cymbals shape emery wheel opening one side in the prior art, this netted groove only limits to cymbals molding sand wheel, other thin type emery wheel then is not suitable for, can not be provided with like this, another is to open more shallow straight trough on slim emery wheel, this groove is far scrapped the place less than diameter, and makes extremely complicatedly, is difficult on the thin type emery wheel of most of specification and implements.

The purpose of this utility model is come therefrom, and a kind of intensity, grinding, the instructions for use that can satisfy the thin type emery wheel will be provided exactly, thin type slotted wheel complete in specifications, that manufacturing is simple, practical.

The utility model adopts following technical scheme to realize above-mentioned purpose: in thin type emery wheel both ends of the surface staggered cone tank is set, the upper and lower notch and the bottom land of both ends of the surface overlap mutually, groove depth is preferably half of thin type emery wheel thickness, the big side of its physical dimension is in the emery wheel outer, the little side of size is towards the emery wheel center position, this groove is wide and dark at the emery wheel peripheral edge portion, and along outer rim in the transition gradually of all positions direction, groove narrows down gradually and shoals, near diameter is scrapped the place, disappear, carry out the transition to diameter basically and scrap near parallel grinding wheel shape.

The reinforcement rib of bull flat thread shape can also further be set on aforesaid thin type slotted wheel, increase its rupture strength, the height of its rib is corresponding with the degree of depth of above-mentioned awl groove, promptly reduce accordingly at emery wheel outer rim height and with the cone tank degree of depth, similarly scrapping the height of locating rib at grinding wheel diameter is zero.

The utility model has following characteristics owing to adopted aforesaid cone tank structure:

1, can improve the intensity of thin type emery wheel, with the thin type abrasive cut-off wheel that common material is made, its revolving strength is than high 10 meter per seconds of common dicing sheet emery wheel～20 meter per seconds; At 85 meter per seconds～90 meter per seconds, its security is much higher than plain wheel by its practical safety line speed of GB.Its reason just is that the peripheral edge portion of this emery wheel alleviates 15%～30% weight than plain wheel, so revolving strength increases.

2, superior interrupted grinding (vibration grinding) effect is arranged, make the thin type emery wheel of structure as mentioned above with general raw material, under middling speed light load situation, its steel cuttings that grinds away is the iron fiber sarconeme shape, length is generally 3～10mm, demonstrates the grinding characteristic of superior high speed heavy load.And the durability of this dicing sheet is higher 1～3 times than plain wheel, and grinding efficiency is high by 30%～70%.

Introduce the utility model below in conjunction with accompanying drawing.

Fig. 1 is the end view drawing of emery wheel described in the utility model.

Fig. 2 is the A-A profile of Fig. 1.

Fig. 3 is the outer rim expanded view of Fig. 1.

Fig. 4 is abrasive wheel end face figure.

Fig. 5 is an emery wheel outer rim expanded view shown in Figure 4.

Fig. 6～Fig. 9 is the emery wheel outer expanded view of several different embodiment.

Fig. 1～Fig. 3 has represented the structure of first embodiment of the present utility model, as shown in the figure, in described thin type slotted wheel outer, the awl groove is that both sides are trapezoidal tapers of semi arch or elliptic arc, and the awl groove of emery wheel both ends of the surface is interspersed, and the position of upper and lower bottom land is interlaced, this groove carries out the transition to the triangle awl that both sides are semi arch or elliptic arc gradually, the awl groove narrows down and shoals, and the physical dimension transition of awl groove finishes near grinding wheel diameter is scrapped the place at last, is a straight line.Among the figure: 1, awl groove, 2, emery wheel, 3, diameter scraps the place, its characteristics are that emery wheel is made simple and practical.

Fig. 3, awl groove and the awl groove structure among the embodiment 1 shown in Figure 4 are identical, and difference is a fluting at interval at it.The characteristics of this awl groove that is intervally arranged are to increase the sand launder ratio, and compacting is aimed at and allowed than large deviation.Among the figure 1, the awl groove, 2, emery wheel.

Fig. 3 is the structural representation of the awl groove outer rim end face of the 3rd embodiment of the present utility model.

As shown in Figure 3, the awl groove is a watt rib shape near the section of emery wheel outer edge, and its awl groove both sides are semi arch or elliptic arc, and drift angle is a fillet, and it is zero that the physical dimension of awl groove is scrapped the place at grinding wheel diameter equally.

Fig. 4 is the 4th embodiment of the present utility model, the awl groove structural representation of emery wheel outer rim end face.

Awl groove drift angle is the triangle awl groove of (two jiaos is acute angle) of fillet among Fig. 4, wherein 1, the awl groove, and 2, emery wheel.

Fig. 5 is the section structure schematic diagram of the awl groove of the 5th embodiment.

In the embodiment shown in fig. 5, to be two jiaos be the square awl groove of arc chord angle to described awl groove.

Fig. 6 is a kind of stack combinations of thin type slotted wheel shown in Figure 5, its awl groove and the relative taper hole 4 that forms of awl groove, and this combinated grinding wheel can satisfy the requirement of delaying emery wheels such as load, middling speed high load capacity, high speed high load capacity in feeding heavy load and the middling speed.
