Description

Oil bath furnace stirring device integrating workpiece loading cavity

Technical Field

The invention relates to an oil bath furnace, and belongs to the field of metal heat treatment processing equipment.

Background

An oil bath furnace is generally used for low-temperature tempering heat treatment of metal workpieces in oil, and the conventional oil bath furnace, such as a bath-bottom directly-heated oil bath furnace disclosed in Chinese patent CN2472174Y, mainly comprises a furnace body, a furnace cover, a heater and the like, wherein the heater is arranged below a steel strip at the bottom of the furnace body. When the workpiece is subjected to oil bath heat treatment, the workpiece is directly placed on a bottom steel plate strip of a furnace body filled with oil for heating, and the temperature of the oil is uniform by utilizing an autonomous thermal convection mode of the oil.

Under this situation, furnace body bottom fluid is by the direct heating to the temperature is higher, only relies on the autonomic hot convection current of fluid and can not make furnace body bottom fluid temperature fully even, leads to placing the work piece in the furnace body bottom to be heated unevenly, influences the thermal treatment quality.

Disclosure of Invention

The invention aims to provide an oil bath furnace stirring device integrated with a workpiece loading cavity, wherein a suspended cavity is used for loading a workpiece, so that the workpiece is not placed at the bottom of a furnace body, and a driving device drives the cavity to rotate so as to stir oil, so that the temperature of the oil is uniform, the workpiece is effectively ensured to be uniformly heated, and the quality of oil bath heat treatment of the workpiece is improved. Meanwhile, the risk that the stirring device scratches the workpiece in the stirring process is avoided.

The invention is realized by adopting the following technical scheme:

an oil bath furnace stirring device integrated with a workpiece loading cavity is arranged on a furnace body and comprises a cavity and a driving device, wherein the cavity comprises a box body, a door plate and a knob; the driving device comprises a motor, a transmission rod, a bearing, a furnace cover and handles, wherein the motor is arranged above the furnace cover, the bearing is arranged in a central hole of the furnace cover, the bottom of the motor is connected with the transmission rod, the transmission rod is embedded in the bearing, the top surface of the box body is connected with the transmission rod, and the two handles are symmetrically arranged on the top surface of the furnace cover.

Furthermore, guide rails are arranged on two sides of the door plate, and the door plate is installed into the door frame through the rectangular guide groove.

Furthermore, each surface and the door plate of the box body are provided with a plurality of holes for oil to flow through.

The invention has the beneficial effects that: the cavity connected below the driving device in a hanging mode is used for loading the workpieces, the workpieces are not placed at the bottom of the furnace body, the driving device drives the cavity to rotate, and therefore oil liquid is stirred to enable the temperature of the oil liquid to be uniform, the problem that the workpieces are heated unevenly in the prior art is effectively solved, and meanwhile the risk that the workpieces are scratched by the stirring device in the stirring process is avoided. And, because the design has the guide rail on door plant both sides, be favorable to the dismouting of door plant on the box body to dress, get the work piece. And because each surface of the box body and the door plate are provided with a plurality of holes, the oil can smoothly flow into the cavity, and the heat convection of the oil in the cavity is realized, so that the temperature of the oil inside and outside the cavity is fully uniform.
