Description

Grinding wheel cutting piece

The present invention relates to a grinding wheel cutting piece, in particular to a grinding wheel cutting machine, and a grinding wheel cutting piece structure having a reinforcing auxiliary piece bonded to a peripheral portion of at least one side of the center mounting hole to strengthen the cutting strength.

The conventional grinding wheel is widely used in high-speed rotary cutting objects, and its structure is as shown in the first figure and the second figure. The grinding wheel 1 is installed in a center hole 2 for high-speed rotary cutting such as a grinder. In the machine or machine tool, the grinding wheel 1 can cut the metal or hard workpiece by the high-speed rotation of the grinder, but the peripheral portion of the hole 2 of the conventional grinding wheel 1 is relatively fragile, insufficient in strength, and easy to cut metal or hard. When the workpiece is workpiece, there is a problem that the entire grinding wheel 1 is broken, the use effect is poor, and the service life is not long, and the heat dissipation effect of the conventional grinding wheel 1 is poor, and the workpiece is cut at a high speed by the grinding wheel 1 In the process, it is easy to generate high heat and affect the safety of use.

In addition, in the related prior patent documents, such as the Republic of China Patent Gazette No. M460746, "The Structure of Tool-Free Disassembly and Grinding Wheels", and the Patent Patent No. I441714, "Chemical Mechanical Abrasives" As is apparent from the typical grinding wheel structure shown in the above first and second figures, there are still problems and disadvantages in that the center portion of the grinding wheel 1 is fragile and cannot be dissipated as described above.

In the above-mentioned conventional or patented grinding wheel, in use and operation, due to the fragile central structure and the difficulty in heat dissipation, the grinding wheel piece may cause the grinding wheel to break and generate high heat when used for cutting metal or hard workpiece. Problems and shortcomings.

Therefore, the grinding wheel cutting piece of the present invention comprises: a cutting piece body, the cutting piece body is provided with a mounting hole at a center of the circle, which can be rotated on a rotating shaft of the rotating machine to cut the object; and at least one reinforcement auxiliary And a reinforcing auxiliary piece is coupled to a peripheral portion of the mounting hole of at least one surface of the cutting piece body, and is integrally formed with the cutting piece body.

Further, in the above-described grinding wheel cutting blade of the present invention, the surface of at least one surface of the cutting blade body is provided with a plurality of undulating wave patterns.

In the above-mentioned grinding wheel cutting blade, the wavy cross-sectional shape of the cutting piece body is a wave pattern with high and low undulations.

The effect of the grinding wheel cutting piece of the present invention is that the auxiliary reinforcing sheet is integrally coupled to the peripheral portion of the mounting hole of the center of the cutting piece body, so that the strength and toughness of the cutting piece body can be enhanced without breaking and damage, and And a plurality of wave patterns provided on at least one surface of the body of the cutting piece to provide a heat dissipation function of the cutting piece body on the cutting workpiece, thereby greatly increasing the service life and safety of the cutting piece body, and thereby enhancing the Industrial use value.

The first figure is a perspective view of a conventional grinding wheel; the second drawing is a sectional view of the first drawing; the third drawing is a perspective view of the first embodiment of the grinding wheel cutting piece of the present invention; the fourth drawing is a front view showing the third The surface structure of the cutting piece body of the drawing; the fifth drawing is the A-A' sectional view of the fourth drawing; the sixth drawing is the second embodiment of the grinding wheel cutting piece of the present invention; the seventh drawing is the sixth drawing A cross-sectional view of B-B'.

Referring to the third, fourth and fifth figures, a first embodiment of the grinding wheel cutting blade 100 of the present invention, wherein the grinding wheel cutting blade 100 comprises a cutting blade body 10, the cutting blade body 10 The corundum and the resin are stirred and placed in a mold for press forming, and then formed by high-temperature barbecue. The cutting piece body 10 is provided with a mounting hole 11 at a center of the core for mounting on a rotating shaft of a rotating machine (not shown). Rotate to cut the object.

At least one reinforcing sheet 20 is bonded to a peripheral portion of the mounting hole 11 of at least one surface of the cutting piece body 10, and is integrally formed with the cutting piece body 10 during the manufacturing process, and the reinforcing sheet 20 is The material is not limited. In this creation, a series of round metal pieces is taken as an example.

Please refer to the sixth embodiment and the seventh figure, which is a second embodiment of the grinding wheel cutting blade 100 of the present invention, wherein the surface of at least one side of the cutting blade body 10 is displayed, and a plurality of wave patterns 12 are provided. The shape of the pattern 12 is not limited. In the creation series, for example, a wave pattern having a high and low undulation in a sectional shape is taken as an example, and the formation pattern of the wave pattern 12 is not limited, and the series is lifted and cut in the present creation. The blade body 10 is integrally formed as an example.

As shown in the fourth to seventh figures, the reinforcing auxiliary sheet 20 of the created grinding wheel cutting piece 100 is coupled to the cutting piece body 10, and the wave pattern 12 of at least one surface of the cutting piece body 10 is provided together. The cutting blade body 10 has the dual effects of strength, toughness reinforcement and heat dissipation enhancement when cutting metal or hard workpieces.

The above-described third and seventh drawings show the grinding wheel cutting piece 100 of the present invention, and the description and the drawings are disclosed to facilitate the clarification of the technical content and technical means of the present invention, and one of the disclosed preferred embodiments, and It does not limit its scope. In addition, all the modifications, alterations, or equivalent substitutions and substitutions of the components of the creations are defined without departing from the spirit and scope of the creation. The scope of the application will be defined by the following patent application scope.
