High-frequency heat treatment equipment for garden cutters Technical Field The invention relates to mower production equipment, in particular to garden cutter high-frequency heat treatment equipment. Background The high-frequency induction heating heat treatment is a key process for improving the surface hardness, wear resistance and fatigue strength of metal parts in the mechanical manufacturing industry. The process has the advantages of high heating speed, high efficiency, easiness in realizing local heating and the like, and is widely applied to the production of various hardware tools. For the mower blade with the linear structure, two sides of the mower blade are provided with edges, the cutting edges of the blade are required to be subjected to high-frequency induction heating and then quenching, and due to the complex production process, the operation mode of manual positioning heating is still adopted in a large amount at present, so that the following obvious defects exist: 1. The consistency of the product quality is poor, and the position, the angle and the residence time of each blade in the induction coil are difficult to be ensured to be completely consistent by manual operation. Small deviations in position from time can lead to deviations in the heated area, uneven depth of hardened layer, and even overheating and burning or underheating. 2. The time interval (transfer time) from manual blanking to quenching medium is influenced by the reaction speed of workers, so that the cooling initial temperature is inconsistent, the metallographic structure and the final hardness are directly influenced, the quality dispersion in the product batch is large, and the rejection rate is high. 3. The production efficiency is low, the productivity bottleneck is obvious, the manual feeding and discharging rhythm is far slower than the heating speed of high-frequency equipment, so that the equipment is always in a waiting state, and the equipment utilization rate is low. And the device is limited by the physical strength and the working time of workers, can not realize 24-hour continuous high-strength operation, and is difficult to meet the requirement of mass production. 4.

The workers repeatedly carry out heavy carrying and positioning operations in a high-temperature environment for a long time, fatigue is very easy to generate, the efficiency is affected, and the risks of safety accidents such as scalding, mechanical injury and the like are increased. In order to solve the problems of unstable quality, low efficiency, potential safety hazard and the like caused by manual operation, the traditional manual high-frequency heat treatment process is urgently needed to be upgraded into a full-automatic feeding and discharging and heating quenching system.
