Problems solved by technology

However, in the process of quenching the motor mandrel by this kind of quenching machine, there is a certain distance between the heating and cooling areas. When the heated motor mandrel is transported on the conveyor belt, the heat at both ends of the motor mandrel will be transferred to the motor mandrel. The inside of the shaft causes the inside of the motor shaft to be cooked, causing damage to the internal structure of the motor shaft and affecting the mechanical properties of the motor shaft
In addition, erecting the motor mandrel on the conveyor belt may easily cause slight bending of the motor mandrel, which affects the straightness of the motor mandrel

Abstract

The invention discloses an automatic quenching device, which includes a frame and an induction coil connected with a high-frequency power supply circuit, and is characterized in that it includes: a rotating lifting mechanism, including air claws arranged longitudinally for clamping shaft workpieces, the The air gripper can rotate on its own axis and vertically lift; an automatic feeding mechanism, located next to the rotating lifting mechanism, sends the shaft workpiece from the discharge box to the rotating lifting mechanism for clamping by the air claw in the rotating lifting mechanism; The material mechanism is located under the rotary lifting mechanism, and is used to receive the quenched shaft workpiece; the induction coil is arranged horizontally, and cooperates with the air claw in the rotary lifting mechanism to clamp the shaft workpiece, and makes the cooling liquid flow through the induction coil location. In this way, the automatic quenching function of the shaft workpiece is realized, and the direct water spray cooling effectively prevents the heat from being transferred to the inside of the workpiece. The air claw of the rotating lifting mechanism clamps the shaft workpiece longitudinally, ensuring the straightness of the shaft workpiece .

Description

technical field [0001] The invention relates to an automatic quenching device and an automatic quenching method using the device to quench both ends of a shaft workpiece (especially a motor mandrel). Background technique [0002] Quenching refers to a heat treatment method that uses high-frequency current (30K-1000KHZ) to locally heat and cool the surface of the workpiece to obtain a surface hardened layer. This method only strengthens the surface of the workpiece at a certain depth, while the core basically maintains the structure and performance before treatment, so it can obtain a combination of high strength, high wear resistance and high toughness. And because of local heating, it can significantly reduce quenching deformation and reduce energy consumption. [0003] The traditional manual quenching method is that the worker directly holds the workpiece, puts the part of the workpiece that needs to be quenched into the induction coil with high-frequency current, and wai...
