Description

Special section of airport runway

Technical Field

The utility model relates to a cutting tool technical field especially relates to a special section of airport runway.

Background

At present, a diamond saw blade is generally adopted for cutting an airport runway, but because the top surface and the side surface of the cutter tooth are simultaneously cut into a material to be cut in the cutting process and are tightly attached and rubbed, the loss is serious, the service life is short, and because of the particularity of the material of the runway, the feed speed, the cutting speed and the cutting depth are often limited to a certain extent, and the requirement of people on the cutting quality cannot be well met.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above-mentioned not enough of prior art, the utility model provides a special section of airport runway solves the shallow problem that reaches the cutting speed slow of the depth of cut that current saw bit exists when cutting the runway.

The invention is realized by the following technical scheme:

the utility model provides a special section of airport runway, is including the saw bit base member that is equipped with the centre bore, a plurality of cutting tool bits have evenly been laid to the outer fringe of saw bit base member, and adjacent two be equipped with the wind hole on the saw bit base member between the cutting tool bit, each the cutting tool bit inclines certain angle to same direction for the saw bit base member, the interval is equipped with a plurality of chip grooves on the cutting tool bit, the cutting tool bit outer fringe of chip groove both sides is equipped with the arch.

Furthermore, each cutting tool bit is provided with four chip grooves and five bulges.

Furthermore, the chip grooves extend from the inner edge to the outer edge of the cutting tool bit, and the inclination angle of each chip groove and each bulge is consistent with the inclination angle of the cutting tool bit.

Further, the protrusion is a circular arc protrusion.

Further, the number of the cutting heads is 24-28.

Compared with the prior art, the beneficial effects of the utility model reside in that:

the special section for the airport runway, which is provided by the utility model, is provided with the cutting tool bit inclined at a certain angle, thereby improving the stress condition of the tool bit during cutting, reducing noise, improving cutting stability, facilitating and fast feeding, and improving the depth of feeding and cutting efficiency; the chip removal groove and the protrusion which are inclined at the same angle with the cutting tool head are arranged on the cutting tool head, so that the chip removal and heat dissipation are facilitated, the cutting is stable, and the service life of the cutting tool is prolonged by the integral design.

Drawings

Fig. 1 is the utility model discloses a special sliced architectural diagram of airport runway.

In the figure:

1. a saw blade substrate; 2. a central bore; 3. a cutter head; 4. a chip groove; 5. a wind hole; 6. and (4) protruding.

Detailed Description

The following examples are presented to illustrate certain embodiments of the invention and should not be construed as limiting the scope of the invention. The present disclosure may be modified from materials, methods, and reaction conditions at the same time, and all such modifications are intended to be within the spirit and scope of the present disclosure.

As shown in fig. 1, a special section of airport runway, including saw bit base member 1 that is equipped with centre bore 2, a plurality of cutting tool bits 3 have evenly been laid to the outer fringe of saw bit base member 1, adjacent two be equipped with wind hole 5 on the saw bit base member 1 between the cutting tool bit 3, each cutting tool bit 3 is for saw bit base member 1 to certain angle of same direction slope, the interval is equipped with a plurality of chip grooves 4 on the cutting tool bit 3, the cutting tool bit 3 outer fringe of chip groove 4 both sides is equipped with arch 6.

Each cutting head 3 is provided with four flutes 4 and five projections 6.

The chip grooves 4 extend from the inner edge to the outer edge of the cutting head 3, and the inclination angle of each chip groove 4 and each protrusion 6 is consistent with that of the cutting head 3.

The protrusion 6 is a circular arc protrusion.

The number of the cutting heads 3 is 24-28.

The cutting blade is provided with the cutting blade head 3 which is inclined at a certain angle, so that the stress condition of the blade head during cutting is improved, the noise is reduced, the cutting stability is improved, the rapid feeding is convenient, and the feeding depth and the cutting efficiency are improved; set up on cutting tool bit 3 with the equal angle's of cutting tool bit 3 slope chip groove 4 and arch 6, make things convenient for the chip removal heat dissipation, the cutting is steady, and overall design has prolonged sliced life.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
