Description

Technical Field

[0001] The utility model relates to the technical field of atmosphere high-temperature lifting furnaces, in particular to an atmosphere high-temperature lifting furnace. Background Art

[0002] A high-temperature lifting furnace is a commonly used heat treatment equipment used for heat treatment of metal materials, especially processes such as quenching and tempering. It improves the hardness, strength and wear resistance of the material by heating the metal material to the required temperature and then cooling it down quickly. An atmosphere high-temperature lifting furnace is a lifting furnace in which a specific atmosphere is introduced into the furnace, such as an inert gas or a chemical gas. The atmosphere high-temperature lifting furnace is suitable for experiments and production that require specific atmosphere conditions.

[0003] When metal is heated in a controlled atmosphere, surface oxidation or decarburization can be avoided, and the surface can also be carburized as required. The door of the atmosphere high-temperature furnace is hinged on the furnace body, that is, when the staff puts in the metal material, they need to turn the door to open and close it, and they need to repeat the above operation when taking out the metal material. Since the internal temperature of the furnace body is high after use, it is inconvenient for the staff to take out the metal material in the above operation method, which has certain risks.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] like Figure 1 , Figure 4 and Figure 5As shown, the atmosphere high-temperature lifting furnace includes a base 1, a furnace body 2 is provided at the upper end of the base 1, a furnace door 3 is provided on one side of the furnace body 2, a rubber strip is adhered at the joint between the furnace body 2 and the furnace door 3, and the furnace door 3 is provided with relatively arranged slots 8, and relatively arranged L-shaped plates 9 are fixedly connected to the furnace body 2, and limiting rods 10 that cooperate with the slots 8 are fixedly connected to the L-shaped plates 9 on both sides, and the limiting rods 10 extend into the slots 8, and the surface of the limiting rod 10 fits the inner wall of the slot 8, and the inner wall of the L-shaped plate 9 fits the surface of the furnace door 3.

[0023] Through the above structure, the furnace door 3 can be limited. How to drive the furnace door 3 to rise and fall, the specific structure is as follows:

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the furnace body 2 is provided with a lifting mechanism for driving the furnace door 3 to lift and lower, and the lifting mechanism includes a groove 4 located in the furnace door 3 and a cavity 6 located in the furnace body 2 which are arranged relatively, and the grooves 4 and the cavity 6 on both sides are aligned respectively, and a tooth plate 5 is fixedly connected in the groove 4, and a driving wheel 7 meshing with the tooth plate 5 is rotatably provided in the cavity 6, and a double-axis motor for driving the driving wheels 7 on both sides to rotate synchronously is provided in the furnace body 2, and shafts are provided at the output ends of the double-axis motors, and the shafts on both sides are respectively fixedly connected to the driving wheels 7 on both sides, and a control button for controlling the driving motor is provided on the base 1, which is convenient for controlling the double-axis motor to drive the driving wheel 7 to rotate forward and reverse.

[0025] Through the above structure, the furnace door 3 can be driven to rise and fall in the vertical direction.

[0026] Embodiment 2

[0027] like Figure 1 , Figure 4 and Figure 5 As shown, the L-shaped plate 9 and the furnace body 2 are connected by bolts and threads.

[0028] Through the above structure, the L-shaped plate 9 can be disassembled, thereby disassembling the furnace door 3.

[0029] When the utility model is implemented, when the furnace body is used to process metal materials, the metal materials need to be put in first. Specifically, the double-axis motor is turned on, and the output end of the double-axis motor drives the driving wheels on both sides to rotate synchronously. Since the driving wheels are engaged with the toothed plate, the driving wheels rotate to drive the furnace door to rise. During the lifting process, the L-shaped plate and the limit rod do not move. With the cooperation of the card slot, the L-shaped plates on both sides can play a limiting role on the furnace door.

[0030] After the metal material is put in for processing, the dual-axis motor is controlled to drive the driving wheel to rotate in the opposite direction to lower and close the furnace door. After the metal material is processed, the above operation is repeated to take the metal material out of the furnace body. During the process of putting in and taking out, there is no need to turn the furnace door, which can avoid the danger of the high-temperature furnace body to the workers when taking out the metal material.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
