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.
Disclosure of Invention
Aiming at the problems in the prior art, the utility model provides an upper open type heat treatment furnace.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an open-top heat treatment furnace, includes the furnace body, the furnace body inner wall is provided with heating device, the furnace body top is provided with the two furnace doors that can open and shut to both sides, two furnace doors all can rotate along the pivot at furnace body lateral wall top and open and shut, the both sides wall outside that the furnace body is relative is fixed with supporting platform, supporting platform is slightly less than the bottom of furnace door.
The opposite surfaces of the double-furnace door are mutually matched step surfaces.
Handles are respectively arranged at the tops of the double furnace doors.
The furnace body top is provided with first electro-magnet, supporting platform top is provided with the second electro-magnet.
The utility model has the advantages that:
the utility model provides an open-top heat treatment furnace, this heat treatment furnace's furnace gate sets up in the furnace body top, opens the back at the furnace gate, can use the hoist with pending piece from the furnace body top directly put into in the furnace body, get the simple high efficiency of process of putting the work piece, and the maintenance cost that brings when having practiced thrift moving parts such as use platform truck.

in the figure: 1-furnace body, 2-furnace door, 3-rotating shaft, 4-supporting platform, 5-step surface, 6-handle, 7-first electromagnet and 8-second electromagnet.
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 rotate along the pivot 3 at 1 lateral wall top of furnace body and open and shut, and furnace door 2 rotates to both sides and opens the back, can use the hoist to directly put into furnace body 1 with pending piece from 1 top of furnace body in, and the process is simple high-efficient, and has saved the maintenance cost that moving parts such as use platform truck brought. Supporting platforms 4 are fixed on the outer sides of two opposite side walls of the furnace body 1, and the supporting platforms 4 can assist in supporting the opened furnace door 2 after the furnace door 2 is opened, so that the weight of the furnace door 2 is prevented from being applied to the rotating shaft 3, and the service life of the equipment is prolonged. The supporting platform 4 is slightly lower than the bottom of the furnace door 2, so that the opened furnace door 2 is completely pressed on the supporting platform 4 under the action of gravity, the furnace door 2 is prevented from falling back due to instability of being supported by the rotating shaft 3, and accidents can be avoided.
The surface that two furnace gates 2 are relative is step face 5 for mutually supporting, and the fitting surface sets up to step face 5, can effectively seal the seam crossing of two furnace gates 2, avoids causing the calorific loss in furnace body 1 through seam crossing, in other embodiments, also can fill sealed insulation material in step face 5 department to reach better sealed heat preservation effect.
The top of the double-furnace door 2 is respectively provided with a handle 6, and the handle 6 can be beneficial to opening the furnace door 2 by using a lifting appliance.
The first electromagnet 7 is arranged at the top of the furnace body 1, and after the first electromagnet 7 is electrified, the furnace door 2 can be effectively sucked, the accidental opening of the furnace door 2 is prevented, meanwhile, the sealing performance of the furnace body 1 is improved, and the heat loss is prevented; the top of the supporting platform 4 is provided with a second electromagnet 8, and after the second electromagnet 8 is electrified, the opened furnace door 2 can be fixed in an auxiliary mode, so that the furnace door 2 is prevented from accidentally falling back and closing.
The following describes the usage of the present invention with reference to the drawings.
The method comprises the following steps: the first electromagnet 7 is powered off, so that the furnace door 2 is separated from the first electromagnet 7;
step two: opening the furnace door 2 by using a lifting appliance, and enabling the furnace door 2 to fall on the supporting platform 4;
step three: the second electromagnet 8 is electrified to adsorb the furnace door 2;
step four: putting the piece to be processed into the furnace body 1 from the top by using a lifting appliance;
step five: the second electromagnet 8 is powered off, the furnace door 2 is closed by using the lifting appliance, and the furnace door 2 is closed by paying attention to the up-down sequence of the step surfaces 5 to prevent the furnace door 2 from being crushed;
step six: electrifying the first electromagnet 7 to enable the first electromagnet to adsorb the furnace door 2;
step seven: 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.
