Description

Technical Field

[0001] The utility model relates to the technical field of quenching machines, in particular to a feeding device and a quenching machine. Background Art

[0002] Saw blades withstand significant cutting forces and wear during use, so their teeth must possess a certain degree of hardness, while the blade itself requires appropriate toughness. Quenching significantly increases the hardness and wear resistance of saw blade teeth, making them more resistant to wear during cutting and thus extending the life of the saw blade. Furthermore, quenching enhances the cutting performance of the saw blade teeth, enabling more efficient cutting and improving work efficiency. Quenching not only affects the performance of the saw blade teeth but also helps improve the overall strength and toughness of the saw blade, making it more stable and reliable during use.

[0003] Currently, the main methods for quenching saw blade teeth include flame quenching, high-frequency quenching, and hard chromium plating. High-frequency quenching uses high-frequency current to generate eddy currents in the saw blade teeth, rapidly heating and quenching the teeth, thereby hardening the tooth surface. However, existing quenching machines cannot control the specific depth of the quenching process, resulting in the quenching of the entire blade surface. Furthermore, current quenching machines are not versatile enough to handle both straight and curved saw blades, resulting in high production costs. Utility Model Content

[0040] Saw blades withstand significant cutting forces and wear during use, so their teeth must possess a certain degree of hardness, while the blade itself requires appropriate toughness. Quenching significantly increases the hardness and wear resistance of saw blade teeth, making them more resistant to wear during cutting and thus extending the life of the saw blade. Furthermore, quenching enhances the cutting performance of the saw blade teeth, enabling more efficient cutting and improving work efficiency. Quenching not only affects the performance of the saw blade teeth but also helps improve the overall strength and toughness of the saw blade, making it more stable and reliable during use.

[0041] Currently, the main methods for quenching saw blade teeth include flame quenching, high-frequency quenching, and hard chromium plating. High-frequency quenching uses high-frequency current to generate eddy currents in the saw blade teeth, rapidly heating and quenching the teeth, thereby hardening the tooth surface. However, existing quenching machines cannot control the specific depth of the quenching process, resulting in the quenching of the entire blade surface. Furthermore, current quenching machines are not versatile enough to handle both straight and curved saw blades, resulting in high production costs.

[0042] To this end, the present application proposes a loading device 1. For processing linear and curved saw blades, workers only need to replace the positioning accessories to achieve rapid positioning and loading of the saw blades. Furthermore, the present application also proposes a quenching machine using the loading device 1, which can meet the quenching requirements of linear and curved saw blades, thereby improving the versatility of the equipment and effectively increasing production efficiency.
