Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for bushing production, and specifically to a high-performance metal bushing heat treatment equipment. Background Technology

[0002] Heat treatment refers to the metal hot working process in which materials are heated, held at temperature and cooled in a solid state to obtain the desired structure and properties. Heat treatment generally does not change the shape and overall chemical composition of the workpiece, and its characteristic is to improve the internal quality of the workpiece.

[0003] A bushing is a cylindrical mechanical part fitted onto a rotating shaft and is a component of a sliding bearing. It is widely used in industry, and its quality directly affects the operation of the entire machine. In the production and processing of bushings, heat treatment is required to improve their performance. However, existing procedures have two main problems: 1. Manual handling with clamps after heat treatment is necessary, which is risky due to burns from the heating elements and the bushing itself, and is inefficient; 2. Uneven heating within the furnace results in poor heat treatment of the bushings. These factors restrict bushing production and cannot meet current production needs. Utility Model Content

[0004] To solve the above problems, the inventor developed a high-performance metal bushing heat treatment equipment based on his expertise in the field of bushing production heat treatment technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-performance metal bushing heat treatment device, comprising a furnace body, heating wires distributed on the bottom and inner wall of the furnace body, a hollow heat distributor disposed in the middle of the furnace body, the heat distributor being placed on a support, an upper end cap connected to the top of the furnace body by screws, a retractable hook disposed on the top of the upper end cap, the hook being movably connected to a crane, a compressed air tank disposed on the left side of the furnace body, and a negative pressure fan disposed on the upper right side of the furnace body.

[0006] Furthermore, the heating end of the heating wire is connected to a heater, which is located at the upper left of the furnace body.

[0007] Furthermore, a compressed air pipe is connected between the compressed air tank and the furnace body, and the end of the compressed air pipe is connected to the lower left side of the furnace body. A first hand valve is installed on the compressed air pipe.

[0008] Furthermore, a negative pressure fan inlet pipe is connected between the negative pressure fan and the furnace body, a second hand valve is installed on the negative pressure fan inlet pipe, and a negative pressure fan outlet pipe is connected to the outlet of the negative pressure fan.

[0009] Furthermore, a hanging ring is connected to the top of the upper end cap, and the upper end cap is semi-circular.

[0010] Furthermore, the hook includes a first telescopic part, a second telescopic part, and a third telescopic part, and the hook moves downward or upward along the vertical line.

[0011] Furthermore, the vehicle is equipped with a sliding groove for the hook to move left and right.

[0012] Furthermore, the heat distributor has distribution holes that are evenly arranged on the heat distributor.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This utility model features a crane installed at the top of the furnace body. The crane allows for the batch placement of bushings to be heated inside the furnace. After heat treatment, the bushings can be removed sequentially using the crane. This replaces manual handling, improves production efficiency, and avoids safety hazards.

[0015] 2. This utility model incorporates a heat distributor within the furnace body, which has distribution holes. After heating by the heater, the generated heat enters the heat distributor through these distribution holes, initiating the heat treatment process on the bushing. This design ensures uniform heating of the bushing, effectively improving the heat treatment outcome and generating greater economic benefits. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a high-performance metal bushing heat treatment device includes a furnace body 1. Heating wires 5 are distributed on the bottom and inner wall of the furnace body 1. A hollow heat distributor 2 is provided in the middle of the furnace body 1 and is placed on a support 3. An upper end cap 6 is connected to the top of the furnace body 1 by screws 7. A retractable hook 17 is provided on the top of the upper end cap 6 and is movably connected to a crane 16. A compressed air tank 9 is provided on the left side of the furnace body 1 and a negative pressure fan 14 is provided on the upper right side of the furnace body 1.

[0023] In this embodiment, the heating end of the heating wire 5 is connected to a heater 4, which is located at the upper left of the furnace body 1. The heater 4 is connected to a 380V power supply.

[0024] In this embodiment, a compressed air pipe 10 is connected between the compressed air tank 9 and the furnace body 1. The end of the compressed air pipe 10 is connected to the lower left side of the furnace body 1, and a first hand valve 11 is installed on the compressed air pipe 10.

[0025] In this embodiment, a negative pressure fan inlet pipe 12 is connected between the negative pressure fan 14 and the furnace body 1, a second hand valve 13 is installed on the negative pressure fan inlet pipe 12, and a negative pressure fan outlet pipe 15 is connected to the outlet of the negative pressure fan 14.

[0026] In this embodiment, a hanging ring 8 is connected to the top of the upper sealing head 6, and the upper sealing head 6 is semi-circular.

[0027] In this embodiment, the hook 17 includes a first telescopic part 1701, a second telescopic part 1702 and a third telescopic part 1703, and the hook 17 moves downward or upward along the vertical line.

[0028] In this embodiment, the traveling trolley 16 has a sliding groove for the hook 17 to move left and right. Due to space limitations in the drawings, the sliding groove is not shown in the drawings. However, this will not affect the understanding of this application document by those skilled in the art.

[0029] In this embodiment, the heat distributor 2 is provided with distribution holes 201, which are evenly arranged on the heat distributor 2.

[0030] In practical operation, the screws 7 on the upper end cap 6 are first removed. The operator uses a remote control to move the gantry crane 16 to directly above the upper end cap 6. The operator then hooks the hook 17 into the hanging ring 8 and slowly raises it. At this time, the first telescopic part 1701, the second telescopic part 1702, and the third telescopic part 1703 of the hook 17 retract sequentially. After the upper end cap 6 is raised, the operator uses the remote control to move it to the side. The operator then uses the remote control to lift the bushing to be heat-treated using another hook 17, and places the bushing sequentially into the furnace body 1. (Refer to...) Figure 2 Then restore the upper end cap 6 to its original position and tighten it with screw 7.

[0031] Heater 4 is activated, and heat is continuously supplied to the interior of furnace body 1 through heating wire 5. The heat generated by heating wire 5 enters heat distributor 2 through distribution hole 201, uniformly heating the bushing. After heat treatment, upper end cap 6 is lifted using gantry crane 16, and then the treated bushings are removed one by one. When heat treating the bushing again, furnace body 1 needs to be purged. First, open the first hand valve 11 and start the negative pressure fan 14. Use industrial air from compressed air tank 9 to purge the gas inside furnace body 1. The negative pressure fan 14 can extract the gas inside furnace body 1 in a timely manner, improving the purging efficiency.
