[0032] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0033] See also Figure 1-2 The utility model provides a technical solution: a tempering furnace with high sealing performance, including an end cover 1, a furnace body 2, and a containing component 3.

[0034] A through hole 10 is formed on the end cover 1 , and the end cover 1 fits in with the open end of the furnace body 2 .

[0035] See also Figure 3 The furnace body 2 includes a shell 21 , a resistor 22 disposed inside the shell 21 , and an isolation cover 23 disposed inside the shell 21 .

[0036] The resistor 22 is configured to be threaded and closely attached to the inner wall of the housing 21 .

[0037] The isolation cover 23 is disposed in the inner circle of the resistor 22, and a plurality of heat-transmitting holes 230 are formed on the isolation cover 23. Figure 4 The receiving assembly 3 includes a movable portion 31 and a receiving portion 32 which is sleeved outside the movable portion 31.

[0038] See also Figure 1-5 The movable part 31 includes an inner rod 311 , a sleeve rod 312 , and a through rod 313 .

[0039] The inner rod 311 is provided with a plurality of bosses 3111 , one end of the inner rod 311 passes through the through hole 10 , and a through hole 3110 is formed in the portion of the inner rod 311 passing through the through hole 10 .

[0040] The sleeve rod 312 is sleeved on the outside of the inner rod 311 .

[0041] The sleeve rod 312 is provided with a plurality of vertical grooves 3120 , and the sleeve rod 312 is provided with a plurality of bosses 3121 .

[0042] The first boss 3111 penetrates through the vertical groove 3120 .

[0043] The penetration rod 313 passes through the penetration hole 3110 .

[0044] See also Figure 1-6The accommodating portion 32 includes a mesh cover 1 321 and a mesh cover 2 322 .

[0045] The inner side of the first mesh cover 321 is fixedly connected to the first boss 3111 , and the inner side of the second mesh cover 322 is fixedly connected to the second boss 3121 .

[0046] The inner rod 311 is pulled upward relative to the sleeve rod 312, and the inner rod 311 drives the boss 1 3111 to slide upward in the vertical groove 3120. The boss 1 3111 drives the mesh cover 1 321 to be relatively away from the mesh cover 2 322. Since the mesh cover 2 322 is fixed to the boss 2 3121, the accommodating portion 32 is opened at this time, and the workpiece to be heat treated can be placed inside the accommodating portion 32.

[0047] The receiving assembly 3 with the workpiece placed therein can be placed in its entirety into the furnace body 2 , and the end cover 1 covers the open end of the furnace body 2 to isolate the receiving assembly 3 from the interior of the furnace body 2 .

[0048] By connecting the resistor 22 to electricity, the high temperature generated by the resistor 22 after being energized will heat treat the workpiece.

[0049] The heat generated by the resistor 22 directly enters the interior of the isolation cover 23 through the heat-transmitting hole 230 , and performs heat treatment on the workpiece in the containing component 3 .

[0050] The mesh-shaped mesh cover 1 321 and mesh cover 2 322 enable the heat inside the furnace body 2 to directly contact the surface of the workpiece.

[0051] The workpieces are dispersedly placed in the accommodating parts 32. The relatively independent placement makes the heating efficiency of the workpieces higher during heat treatment. Multiple workpieces can be placed in multiple accommodating parts 32 at the same time. The tempering furnace heat treats multiple workpieces at the same time, and the efficiency of heat treatment is improved.

[0052] In addition, when the end cover 1 is covered on the open end of the furnace body 2, the portion of the inner rod 311 passing through the through hole 10 is exposed to the outside of the tempering furnace, and the through hole 3110 on the inner rod 311 is also exposed to the outside of the tempering furnace. The through rod 313 can be inserted into the through hole 3110. The through rod 313 is used to block the end cover 1 so that it will not open upward due to the high pressure in the furnace body 2. The heat utilization rate inside the furnace body 2 is high, and the heat treatment efficiency of the workpiece is also higher.

[0053] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description. The technical scope of this utility model is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
