The invention discloses a novel induction quenching device of a guide wheel of a hydraulic excavator. The novel induction quenching device comprises a heating unit, a profiling sensor, a positioning device and a lifting mechanism, wherein the profiling sensor is connected with the heating unit through a feeding mechanism and is respectively formed by an upper half-ring sensor and a lower half-ring sensor; the positioning device and the lifting mechanism are of split-type structures; the lifting mechanism is arranged in a cooling system. The novel induction quenching device is simple in structure and convenient to operate, wherein only is one full-ring sensor is restructured into the two half-ring sensors, so that the characteristics of high efficiency and good economy of the original scheme are maintained. Most importantly, a material turning mechanism is not required, so that the complexity of equipment is decreased and the waiting time caused by turning materials is shortened; the problems of deformation of a radial plate and a wheel hub, which are caused by double quenching, do not need to be considered in designing, so that the time is saved and the production efficiency is improved.
Description
technical field [0001] The invention relates to an induction device, in particular to an induction hardening device and a quenching method for a guide wheel of a hydraulic excavator. Background technique [0002] At present, there are two methods commonly used for guide wheel quenching. [0003] Method 1: Continuously scan surface induction hardening with profiling sensor (such as figure 1 shown); continuous induction heating and quenching, the workpiece rotates axially, the inductor 14 is stationary relative to the workpiece 11, and is quenched while heating. However, this solution has disadvantages: 1. There is a soft band on the surface after heat treatment; 2. The heating time is long and the work efficiency is low; 3. The gap control precision between the sensor and the workpiece is low, which may easily cause uneven depth of hardened layer. [0004] Method 2: Simultaneous induction heating and quenching, first quenching one side, then flipping through the turning mec...
