Oil bath furnace stirring device of integrated workpiece loading cavity

Abstract

The invention relates to an oil bath furnace stirring device of an integrated workpiece loading cavity. The oil bath furnace stirring device comprises a cavity and a driving device and is characterized in that the cavity is composed of a box body, a door plank and a rotary knob; the door plank and a door frame are arranged on one side of the box body, and a rectangular guide slot is formed in thedoor frame; the rotary knob is arranged on the right end face of the door frame; a plurality of holes allowing oil to circulate are formed in all surfaces of the box body and in the door plank; the driving device is composed of an electromotor, a driving rod, a bearing, a furnace lid and two handles; the electromotor is arranged above the furnace lid; the bearing is arranged in a central hole of the furnace lid; the driving rod is connected with the bottom of the electromotor and is embedded in the bearing; the top surface of the box body is connected with the driving rod; and the two handlesare arranged on the top surface of the furnace lid. According to the oil bath furnace stirring device, a hanging cavity is adopted to load a workpiece to prevent the workpiece from being placed at thebottom of the furnace body with non-uniform oil temperature, and at the same time, the driving device drives the cavity to rotate to stir the oil to enable the oil temperature to be uniform, so thatthe problem in the prior art that the workpiece is not heated uniformly is solved, and the the quality of the workpiece oil bath thermal treatment is effectively ensured.

Description

technical field [0001] The invention relates to an oil bath furnace, which belongs to the field of metal heat treatment processing equipment. Background technique [0002] Oil bath furnaces are usually used for low-temperature tempering heat treatment of metal workpieces in oil liquid. The existing oil bath furnaces, such as the "bath bottom direct heating oil bath furnace" disclosed in Chinese patent CN2472174Y, mainly consist of a furnace body, a furnace cover and a heating element. The heater is set under the steel strip at the bottom of the furnace body. In the oil bath heat treatment of the workpiece, in the past, the workpiece was directly placed on the steel strip at the bottom of the furnace body filled with oil for heating, and the temperature of the oil was made uniform by using the self-convection method of the oil. [0003] In this situation, the oil at the bottom of the furnace body is directly heated, so the temperature is relatively high. Only relying on the ...

Problems solved by technology

[0003] In this situation, the oil at the bottom of the furnace body is directly heated, so the temperature is relatively high. Only relying on the self-convection of the oil liquid cannot make the temperature of the oil liquid at the bottom of the furnace body fully uniform, resulting in uneven heating of the workpiece placed at the bottom of the furnace body.
