Well furnace is a periodic furnace, which is suitable for the heat treatment of rod and long shaft parts. The structure of the well furnace is: the body of the furnace is a deep cylindrical well, the workpiece is vertically loaded into the furnace by a special crane for heating or heat treatment. Most of the current domestic enterprise well type heat treatment furnace workpiece sling are common hook, crown when the heat treatment has been hanging artifacts, affect the efficiency of the crown, the other hook does not have automatic rotary positioning function, cause artifacts in uneven heating or quenching heat treatment process, affecting the effects of workpiece surface heat treatment, especially for some need high quality heat treatment of workpiece, automatic rotating hook function is particularly important. Although the rotary hook is used in some enterprises, but the large tonnage of the rotary hook is basically imported from abroad, the price is expensive, it is more difficult to buy.
The motor outputs at a low speed through a three-stage planetary gear reducer, which transmits torque to the hook through the coupling, thus driving the hook to rotate the heat-treated workpiece. The reducer is fixed on the hook bracket in the form of flange. In the process of lifting the workpiece, there will be a collision. In order to avoid the shaking of the hook, the hook handle is fixed with a self-aligning roller bearing, and it is also convenient to adjust the hook installation error.
The opening and closing distance of the guide rail on the left and right sides of the well furnace can be adjusted to suit different sizes of heat treatment furnace Wells. Open the motor switch on the rotating hook device, and the workpiece will automatically rotate in the heat treatment furnace well at a speed of about 12r/min, so as to achieve the purpose of heat treatment homogenization.
