Description
Technical Field
The utility model belongs to the technical field of metal heat treatment, especially, relate to an open heat treatment furnace on.
Background
Heat treatment of metals is one of the important processes in mechanical manufacturing, and heat treatment generally does not change the shape and overall chemical composition of the workpiece, but imparts or improves the performance properties of the workpiece by changing the microstructure inside the workpiece, or changing the chemical composition of the surface of the workpiece, as compared to other machining processes. Heat treatment processes are often necessary to improve or modify the original structure within the metal workpiece to achieve desired performance properties. The heat treatment furnace is the indispensable equipment among the heat treatment process, and at present, what the heat treatment furnace adopted mostly is that open furnace gate structure is opened to the side, when getting the piece, needs the platform truck to shift out from the stove earlier, places the piece of treating in the platform truck surface moves into the stove again, and the process is comparatively loaded down with trivial details, especially when the work piece is great, also is a challenge to the platform truck.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, the upper open type heat treatment furnace belongs to the technical field of metal heat treatment, has simple structure and high use efficiency, and can save the maintenance cost caused by using movable parts such as a platform car and the like.
The utility model discloses an open-top heat treatment furnace, including furnace body 1, 1 inner wall of furnace body is provided with heating device, and 1 top of furnace body is provided with can be to the two furnace doors 2 that both sides opened and shut, and two furnace doors 2 all can follow slide 3 at 1 top of furnace body and slide to both sides, and furnace door 2 opens the back to both sides, can use the hoist with the pending piece from 1 top of furnace body directly put into furnace body 1 in, the simple high efficiency of process, and avoided the maintenance cost that moving part such as use platform truck brought. The bottom of the double-furnace door 2 is fixed with a transmission rack 4, the transmission rack 4 is arranged on the outer side of the furnace body 1 and is consistent with the opening and closing direction of the furnace door 2, the transmission racks 4 at the bottom of the two furnace doors 2 are meshed with different transmission gears 5 respectively, the two transmission gears 5 are fixed on the same surface of the outer side of the furnace body 1, the two transmission gears 5 are symmetrically arranged on the same outer surface of the furnace body 1, and when the transmission gears 5 rotate, the opening and closing of the furnace door 2 are driven by the meshing of the transmission racks 4.
The opposite surfaces of the double furnace doors 2 are mutually matched step surfaces 6, the matching surfaces are set to be the step surfaces 6, the joint of the two furnace doors 2 can be effectively sealed, the heat loss in the furnace body 1 caused by the joint is avoided, in other embodiments, the step surfaces 6 can be filled with sealing heat-insulating materials, and a better sealing heat-insulating effect can be achieved.
Two furnace gate 2's opposite face department all is provided with anticreep dog 7, and inside furnace body 1 was arranged in to anticreep dog 7, anticreep dog 7 was spacing as machinery, can effectively prevent that furnace gate 2 from droing from 1 top of furnace body when opening when maloperation or equipment are malfunctioning, avoids the emergence of accident.
The outer surface of the furnace body 1 is fixed with a synchronous gear 8, the synchronous gear 8 is meshed with the two transmission gears 5 simultaneously, and the synchronous opening and closing of the furnace doors 2 at two sides can be realized through the transmission of the synchronous gear 8.
The synchronous gear 8 can move up and down along the height direction of the furnace body 1, and when the synchronous gear 8 is meshed with the transmission gear 5 at the upper position, the synchronous opening and closing of the furnace door 2 can be realized; when the synchronous gear 8 moves downwards, the synchronous gear can be separated from the two transmission gears 5, so that the opening and closing conditions of the two side furnace doors 2 can be respectively controlled.
The following describes the usage of the present invention with reference to the drawings.
The method comprises the following steps: the synchronous gear 8 is lifted to be meshed with the two transmission gears 5 simultaneously;
step two: the synchronous gear 8 is rotated to synchronously open the furnace doors 2 at the two sides;
step three: putting the piece to be processed into the furnace body 1 from the top by using a lifting appliance;
step four: the synchronous gear 8 is rotated to synchronously close the furnace doors 2 at the two sides;
step five: the heating device is started.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims.
