Problems solved by technology
But for large mechanical workpieces, it is difficult for one person to operate, and because the metal workpieces are in a high-temperature state, workers cannot get too close, and only two or more workers can work together to operate, which affects the quality of quenching operations. efficiency

The invention discloses an installation method of a lifting transfer device for quenching large machine workpieces. The method includes the following steps that (1) a supporting frame is fixed to the ground of a workshop with foundation bolts; (2) a horizontal rotating drive mechanism is installed at the top of the supporting frame; (3) a lifting mechanism is installed on the horizontal rotating drive mechanism; and (4) the horizontal rotating drive mechanism and the lifting mechanism are controlled to operate, and the large machine workpieces in a heating furnace are transferred into a quenching bath. According to the installation method, the design is reasonable, the structure is simple, reliability is high, rotary lifting operation of 360 degrees can be executed in the workshop, and the operation range is wide; and moreover, the safe reliability is high, dwelling time of the workpieces in the air is shortened, and quenching quality is fully improved. Small workpieces are put into the heating furnace through a containing box and then are taken out after heating is completed, the containing box can be lifted up directly by the lifting mechanism, the multiple small workpieces can be put into the quenching bath for quenching at a time, the labor intensity of workers is greatly relieved and production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of heat treatment, in particular to an installation method of a hoisting transfer device for quenching large mechanical workpieces. Background technique [0002] Quenching is a metal heat treatment process in which a metal workpiece is heated to an appropriate temperature and maintained for a period of time, and then immersed in a quenching medium for rapid cooling. Quenching can improve the hardness and wear resistance of metal workpieces. The quenching pool is set next to the heating furnace. After the metal workpiece heating process is completed, the furnace door is opened, and the trolley where the metal workpiece is placed is pushed out. Manually use clamping or hooking tools to put the small metal workpiece into the cold water of the quenching pool for quenching. But for large mechanical workpieces, it is difficult for one person to operate, and because the metal workpieces are in a high temperature s...
