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 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.
