Abstract:In order to reduce the labor intensity of the operator, to improve the working conditions, to improve the efficiency and stability of the loading and unloading of the shaft tube in quencher production line on shaft tube, and to improve the level of automation, the automatic loading and unloading equipment in intelligent quencher production line on shaft tube was developed. The composition of the quencher production line on shaft tube was introduced, and the working principle and the overall mechanical structure design of the quencher production line on shaft tube were elaborated. The composition of the automatic loading and unloading equipment in the quencher production line on shaft tube was introduced, which mechanical structure design was elaborated. The PLC control system was adopted in the quencher production line. The actions of the implementing equipments in the quencher production line were coordinated. The operation of the production line is very convenient, and the control is flexible, which can meet the production requirement.
