Abstract

The invention relates to a quenching robot. The quenching robot comprises a quenching tank and a lifting mechanism. The upper end of the quenching tank is opened, and the quenching tank is further provided with an inlet pipe and an outlet pipe. The outlet pipe is located below the inlet pipe. A pipeline pressurizing pump for pressurizing quenching media is arranged between the outlet pipe and the inlet pipe. The lifting mechanism comprises a motor, a chain wheel and a chain. One end of the chain is a quenched workpiece connecting end, and the other end of the chain is a free end. According to the quenching robot, the motor is used for driving a quenched workpiece to move up and down, so that the quenched workpiece is subjected to alternated cooling in air and liquid media, manual quenching operation is replaced, the labor intensity of quenching workers is relieved, the quenching quality can be stabilized as well, and the ideal quenching effect is achieved. Through control over the rotation direction, the rotation speed, the staying time and the like of the motor, the staying time, namely the cooling time, of the quenched workpiece in the air and the quenching media is controlled, and accordingly the purpose of changing the cooling speed is achieved.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a quenching robot. Background technique [0002] Quenching is the most important process in heat treatment. In this process, the workpiece is heated and kept warm, and then cooled to obtain lower bainite, martensite or their mixed structure; cooling is the most critical process in the quenching process. Cooling If the speed is slow, martensite cannot be obtained, and the purpose of quenching cannot be achieved. If the cooling speed is fast, it will easily cause deformation and cracking of the workpiece, and the workpiece will be scrapped. In order to prevent deformation and cracking of the workpiece, the cooling rate of the workpiece should be slowed down as much as possible. The ideal cooling rate is: at the ferrite transformation temperature Ar 3 Or pearlite start transition temperature Ar 1 Above, the cooling rate can be very slow, in Ar 3 or Ar 1 The cooling rate ...
