The application discloses a hard alloy saw blade suitable for wood cutting, which comprises a saw blade base body, a plurality of alloy cutter heads are arranged on the outer circumferential side of the saw blade base body at a circumferential interval, the outer side end of the saw blade base body is divided into a plurality of cutter head bodies by the plurality of alloy cutter heads, the alloy cutter heads are arranged at one end of the cutter head bodies and extend outward from the cutter head bodies, first chip removal and heat dissipation holes are formed between adjacent cutter head bodies, and a plurality of second chip removal and heat dissipation holes are uniformly arranged on the saw blade base body in a circumferential direction. The plurality of cutter head bodies are arranged on the saw blade base body, the first chip removal and heat dissipation holes formed between adjacent cutter head bodies can quickly remove the sawdust generated during cutting and timely dissipate heat, friction and temperature rise caused by the fact that the sawdust is stuck between the cutter head bodies and wood are avoided, the wood is affected by heat generation, and the temperature dissipation effect of the second chip removal and heat dissipation holes on the saw blade base body is further enhanced.

This utility model belongs to the technical field of tempering equipment, and in particular to a tempering device for ultra-large carbide saw blade substrates. It includes a main body box, a sealing frame fixedly installed on the front of the main body box, a movable shaft movably installed on the right side of the sealing frame, an external box door movably installed on the surface of the movable shaft, and a protective box fixedly installed on the top of the main body box. This tempering device can achieve precise temperature control of ultra-large saw blade substrates through a double-layer insulation layer and a blower-driven circulating air system (first branch pipe, air inlet pipe, and air return port), effectively improving temperature uniformity. The modular push-pull plate and tension rod structure, combined with a return spring for automatic clamping, ensures the long-term stability of the fixed plate while facilitating rapid maintenance of the device, thereby improving maintenance efficiency. The double insulation design combined with a waste heat recovery system reduces energy consumption, effectively solving the problems of deformation and excessive energy consumption during the tempering process of large saw blades.

The invention discloses a tooth-breaking-free hard alloy reciprocating saw and a machining method thereof, the tooth-breaking-free hard alloy reciprocating saw is applied to the technical field of reciprocating saws, according to the technical scheme, the tooth-breaking-free hard alloy reciprocating saw comprises a saw blade base body and a plurality of tooth holders evenly arranged on the saw blade base body, and hard alloy sawteeth are fixedly connected to the tooth holders; a centripetal inclined surface, a circumferential inclined surface, a front cutter inclined surface, a rear cutter inclined surface, a surface inclined inclined surface and a top inclined inclined surface are respectively formed on the hard alloy sawteeth based on a grinding mode; the method has the technical effects that the production process is simplified, and the cutting performance is improved.

The invention relates to the technical field of sawtooth welding, and discloses a full-automatic hard alloy sawtooth pre-welding machine which comprises a machine base, two sawtooth clamps are alternately inserted and limited on a conveying base, a saw blade adjusting piece is arranged on one side of the machine base, a circular saw blade body is arranged on the saw blade adjusting piece, and a clamp locking mechanism is arranged at one end of the machine base. Compared with the prior art, the saw blade welding device has the beneficial effects that when the sawtooth clamp moves along with the conveying base, the first lead screw of the saw blade adjusting piece drives the saw blade fixing device to move horizontally and is matched with the constant-angle driving device to drive a circular saw blade body to rotate tooth by tooth, and grooves to be welded correspond to sawteeth one to one; and then an inserting piece of a clamp locking mechanism is inserted into an inserting groove for preliminary positioning, a right trapezoid block and a limiting block are subjected to double locking, and it is ensured that the positions of sawteeth are stable and free of deviation after feeding. By means of the double-clamp design, when one clamp is used for welding, the other clamp synchronously completes feeding preparation, and the process limitation of'welding-waiting-feeding 'of a single clamp is broken through.

The utility model relates to the technical field of cutting saw blades, in particular to a composite type noise reduction hard alloy saw blade structure which comprises two side protection plates and a plurality of splicing saw blades located between the two side protection plates, the splicing saw blades are each of a fan-shaped structure, and the splicing saw blades jointly define a ring. The two side protection plates are fixed into an integrated structure through screws so that the splicing saw blades can be clamped and positioned between the two side protection plates, arc-shaped strips are fixed to the outer arcs of the splicing saw blades, the fan-shaped splicing saw blades are clamped between the two side protection plates, when a single saw blade is abraded or damaged, the splicing saw blades can be replaced independently, and the splicing saw blades can be replaced independently. The spliced saw blades of the fan-shaped structures are matched with the connecting holes to limit the overall vibration of the saw blades, reduce the propagation path of sound waves and achieve the noise reduction effect, the connecting holes are matched with the heat dissipation holes to help the saw blades to dissipate heat in the using process, the saw blades are prevented from being overheated, and the service life of the saw blades is prolonged.

The utility model relates to the technical field of saw blades, in particular to a high-performance aluminum alloy ultrathin saw blade which comprises a saw blade base body and saw teeth. The sawteeth are arranged on the peripheral side wall of the saw blade base body, the saw blade base body and the sawteeth are made of high-speed steel or hard alloy, the two side faces of the saw blade base body are each provided with a plurality of annular conical reinforcing strips distributed at equal intervals, and the tip ends of the conical reinforcing strips are distributed in the radial direction away from the side of the center of the saw blade base body. The sum of the thickness of the saw blade base body and the thickness of the conical reinforcing strips on the two sides ranges from 0.1 mm to 0.5 mm, the conical reinforcing strips on the two sides are distributed in a staggered mode, and heat dissipation type scale marks are engraved on the tops of the conical reinforcing strips in the length direction. The saw blade is simple in structure, high in hardness and high in heat dissipation and self-protection strength.
