The sickle heating process by high-frequency induction heating equipment

The sickle is very familiar to people who often farm. It is a common agricultural tool for mowing grass, harvesting wheat, and rice in rural areas in the past. Although it is not common now, it is still commonly used by the older generation. It is made of blades and wooden handles. In farming, because the sickle is subjected to constant friction and force, it wears out very quickly. The sickle that has been used for a long time will be rubbed back and forth on graphite or hard things in order to become sharper and last longer. In addition to the old-fashioned method, it is very important to quench and heat the sickle by high-frequency heating equipment.

The blade of the sickle is basically clamped steel, and the outer layer is relatively soft. If it falls off the table, it will not hurt on hard soil or soft places, but it will hurt if it falls on the concrete floor. The processing method of the sickle on the market is that the blade is stamped from a thin plate through a mold. Because the plate used is relatively thin, usually with a thickness of 1.0mm or 1.5mm, the strength of the formed blade is not high, and it is easy to bend, deform, or even break when used. . However, if the thin metal material is blanked into a blade shape, the wide mouth of the sickle is sharpened, and the ribs are pressed on the blade to strengthen the strength of the blade. Finally, the blade is quenched and tempered by high-frequency heating equipment. , Enhance the hardness, toughness and friction of the blade. Using this equipment for quenching heat treatment, not only the quenching part can be selected, but also the inductors are made according to the specifications of the workpiece, which can effectively ensure the uniformity of the quenching temperature and quenching area. The fast quenching speed avoids the oxidation and decarburization of the blades of the sickle in contact with air. Thereby ensuring and improving the quenching effect of the blade, so that the hardness and wear resistance of the blade after quenching have reached the required standard.

Through the above understanding, I understand that with the development of the times, all walks of life are growing rapidly, and the sickle blade has also taken off the method of heating with fire in the past, and uses modern high-frequency heating equipment for quenching and heating. Therefore, we must always follow the pace of the times and manufacture better and more advanced equipment for our customers.
