What is the working state of the tempering material basket
During the heating process of the basket, the mechanical gripper installed on the lifting cylinder of the vertical vacuum quenching furnace hooks the rod 8 of the basket to make the basket hang in the air and heat up in the heating furnace of the vertical vacuum quenching furnace. After the heat treatment and heating process time of the workpiece arrives, the upper and lower heat insulation of the heating chamber on the vertical vacuum quenching furnace is opened at the same time.
When the basket left material basket flip fulcrum 7 and right material baskets of reverse pivot shaft 6 into the vertical vacuum quenching furnace left plate spacing grooves of the left knee and right knee right plate spacing grooves, mechanical gripper open, material basket of tie 8 from mechanical gripper hook to pull, automatic falling into a vertical vacuum quenching furnace left plate spacing grooves of the left knee and right knee plate spacing grooves at the right place, at the same time left knee and right lifting platform in the respective drive cylinder driven by rapid decline, make the basket from the heating chamber under hot close range, convenient vertical vacuum quenching furnace close the heating chamber under hot;
Material basket into the left and to the left of the lift table plate frame limit slot and right knee right limit slot plate, a left turn basket fulcrum 7 and right material basket flip fulcrum 6 stress, due to material defect left turn basket fulcrum 7 and right material basket flip fulcrum below 6 sets on stock baskets of center of gravity, the upper material basket is always heavy bottom light, so the basket will be turned down, and because the material basket left turn basket fulcrum 7 and right material baskets of rollover protection eccentric shaft 6 is welding, material basket to flip the direction of the fixed direction toward the center of gravity, the material basket in limit lever to the greatest turn around 90 °;
After the basket is flipped, the workpiece placed in the drawer material box 3 must be flipped and fall into the quenching tank in a state of free fall. Because the basket does not enter the water, greatly reduce the basket down stroke, save a considerable amount of workpiece quenching transfer time, so the workpiece transfer time < 6s and the basket does not enter the water goal has been realized.
