DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the embodiments.

[0025] See also Figure 1-4 The utility model provides a metal heat treatment furnace with convenient furnace door opening and closing, comprising a furnace body 1, a controller 2 is arranged at the top of the furnace body 1, a concave frame 3 is arranged at the front end of the furnace body 1, movable grooves 7 are arranged at both ends of the inner wall of the concave frame 3, a driving motor 4 is arranged at the bottom end of one side of the concave frame 3, and a lifting mechanism 5 is arranged at the driving end of the driving motor 4;

[0026] Limiting slide grooves 8 are arranged on both sides of the inner wall of the furnace body 1, and limiting sliders 9 are slidably installed on the inner walls of the limiting slide grooves 8. A placing plate 10 is fixed to the top of the limiting slider 9, and a pushing mechanism 11 is arranged at the center of the top of the placing plate 10.

[0027] By starting the lifting mechanism 5 to drive the sealing door 53 to move up and down, the furnace body 1 can be opened easily, thereby improving the practicality of the metal heat treatment furnace.

[0028] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth to explain in detail that the lifting mechanism 5 includes a threaded screw 51, and the bottom end of the threaded screw 51 is fixed to the driving end of the driving motor 4;

[0029] The lifting mechanism 5 further includes two movable blocks 52 , which are respectively slidably mounted on the inner walls of the movable groove 7 , and sealing doors 53 are commonly fixed on opposite sides of the movable blocks 52 .

[0030] First, by starting the driving motor 4, it can drive the threaded screw 51 to rotate, and then drive the movable block 52 to move up and down. The movable block 52 can drive the sealing door 53 to move up and down, so that the furnace body 1 can be quickly opened, thereby improving the practicality of the metal heat treatment furnace.

[0031] Further as Figure 1 , Figure 2 ,and Figure 4As shown, it is worth explaining in detail that one of the movable blocks 52 is threadedly connected to the threaded screw 51, and a sealing block 6 is provided at the top of the sealing door 53, and the sealing block 6 is fitted with both sides of the top of the concave frame 3.

[0032] Through the cooperation between the concave frame 3 and the sealing door 53, the furnace body 1 can be sealed more completely, thereby further improving the practicality of the metal heat treatment furnace.

[0033] This solution has the following working process: after the metal is heated, the sealing door 53 of the furnace body 1 needs to be opened. First, by starting the driving motor 4, the threaded screw 51 can be driven to rotate, and then the movable block 52 can be driven to move up and down. The movable block 52 can drive the sealing door 53 to move up and down, so that the furnace body 1 can be quickly opened. At the same time, when the sealing door 53 slides upward, it can drive the mounting part 113 to be subjected to force, and then the rotating part 112 can be driven to be subjected to force, so that the placement plate 10 can be driven to slide and be subjected to force, so that the placement plate 10 can slide out of the inner wall of the furnace body 1, and then the processed metal can be quickly taken out, further improving efficiency.

[0034] According to the above working process, it can be known that: through the cooperation between the lifting mechanism 5 and the pushing mechanism 11, it can open the sealing door 53 while also driving the placement plate 10 to bear force through the pushing mechanism 11, thereby realizing the removal of the heated metal on the surface of the placement plate 10.

[0036] The pushing mechanism 11 further includes a mounting member 113 , which is fixed at the center of the bottom end of the sealing door 53 .

[0037] The pushing mechanism 11 can mainly realize that while the sealing door 53 is sliding, force can also be applied through the rotating member 112 , thereby driving the placement plate 10 to slide under force.

[0038] Further as Figure 3 As shown, it is worth explaining in detail that the other end of the rotating member 112 is rotatably mounted on the inner wall of the mounting member 113 .

[0039] The rotating member 112 can mainly drive the mounting member 113 to rotate and bear force, thereby driving the placement plate 10 to slide under force.

[0040] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that support frames 12 are fixed to the four corners of the bottom end of the furnace body 1.

[0041] The support frame 12 is mainly used to fix and support the furnace body 1 .

[0042] In summary: by starting the lifting mechanism 5 so that it can drive the sealing door 53 to lift, it is possible to facilitate the opening of the furnace body 1, and while the furnace body 1 is opened, when the sealing door 53 slides upward, it can drive the mounting member 113 to be subjected to force, and then drive the rotating member 112 to be subjected to force, thereby driving the placement plate 10 to slide and be subjected to force, so that the placement plate 10 can slide out of the inner wall of the furnace body 1, and then the processed metal can be quickly taken out, further improving efficiency.

[0043] The drive motor 4 can be purchased on the market. The drive motor 4 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
