Embodiment 1

[0043] Such as Figure 1-2 As shown, the high-strength heat-resistant and chip-removing titanium film saw blade according to the embodiment of the present invention includes a saw blade base 1, the outer surface of the saw blade base 1 is coated with a titanium film, and a center is provided at the center of the saw blade base 1. hole 2, the outer side of the central hole 2 is provided with several heat dissipation holes 3 along the circumferential direction, and the outer surface of the saw blade base 1 is provided with several saw teeth 4 and chip removal grooves 6 alternately, and the saw teeth 4 are welded and fixed There is a cutter head 5, and an extension groove 7 is communicated with one side of the chip removal groove 6 close to the center of the saw blade base body 1 .

Embodiment 2

[0045] Such as Figure 1-4 As shown, the material of the saw blade substrate 1 is alloy, the thickness of the titanium alloy film is 2-7 microns, the cutter head 5 is a ceramic alloy cutter head, and is welded by a high-frequency welding method by a fully automatic gear welding machine Welded on the sawtooth 4, both sides of the chip removal groove 6 are arc-shaped structures, the number of the chip removal groove 6 is ten, and the length of the chip removal groove 6 and the extension groove 7 is One-fifth of the radius of the saw blade substrate 1. It is not difficult to see from the above design that through the design of the chip removal groove 6, the accumulation of flying chips generated by the saw blade on the saw blade is reduced, and the saw blade will generate a lot of heat during the high-speed cutting process, and several cooling holes 3 are formed. Convection heat dissipation, good heat dissipation effect, improving the service life and adaptability of saw blades ...

Embodiment 3

[0047] Such as Figure 1-2 As shown, according to an embodiment of the present invention, a high-strength heat-resistant and chip-removing titanium film saw blade processing technology is also provided, which is used for a high-strength heat-resistant and chip-removing titanium film saw blade, comprising the following steps;

[0048] Step S101, laser cutting: use a laser cutting machine to cut the substrate from the sheet material, the cut substrate includes the central hole 2, the heat dissipation hole 3, the serration 4, the chip removal groove 6 and the extension groove 7;

[0049] Step S103, quenching and tempering: first apply pressure to both ends of the saw blade base 1 with a clamp, then pressurize and quench the saw blade base 1, rinse the saw blade base 1 with clean water after quenching, and remove the surface of the saw blade base 1 salting, and then use the clamp to apply pressure to the saw blade substrate 1 and then put it into the tempering furnace for pressuri...

Abstract

The invention discloses a high-strength heat-resistant chip removal titanium film saw blade and a machining process thereof. The high-strength heat-resistant chip removal titanium film saw blade comprises a saw blade base body; the outer surface of the saw blade base body is plated with a titanium film; a center hole is formed in the center of the saw blade base body; a plurality of heat dissipation holes are formed in the outer side of the center hole in the circumferential direction; a plurality of sawteeth and chip grooves are arranged on the outer surface of the saw blade base body in a staggered mode; tool bits are welded and fixed to the sawteeth; and the sides, close to the center of the saw blade base body, of the chip grooves are communicated with extension grooves. The saw blade has the advantages that accumulation of flying chips generated by the saw blade on the saw blade is reduced through the design of the chip grooves, the saw blade can generate a large amount of heat in the high-speed cutting process, the heat dissipation holes form convection heat dissipation, the heat dissipation effect is good, the service life of the saw blade is prolonged, and the adaptability of the saw blade is improved.

Description

technical field [0001] The invention relates to the technical field of saw blade processing, in particular to a high-strength heat-resistant chip removal titanium film saw blade and its processing technology. Background technique [0002] The saw blade is one of the commonly used tools for cutting. The structure of the saw blade in the prior art is: a cemented carbide blade as a cutting edge is brazed on the quenched and tempered medium carbon steel or low alloy steel tool holder. It is ground to the required size and precision. The blade of this structure becomes blunt soon when the blade of this structure is sawing the man-made board that contains caking agent, needs sharpening, not only reduces production efficiency, increases manufacturing cost, also affects its processing accuracy. [0003] Tungsten carbide saw blades are composed of a saw blade base and a diamond alloy cutter head inlaid on the circumferentially evenly distributed serrations. They are widely used in r...
