Description

Technical Field

[0001] The utility model belongs to the technical field of aging furnaces, and specifically relates to an aging furnace for cable production. Background Technique

[0002] An aging furnace, also known as an aging treatment furnace or an aging heat treatment furnace, is an industrial furnace specifically used for the heat treatment process of metal materials. Its main function is to perform heat treatment on metal parts that have undergone cold working or hot working to change the microstructure of the material, thereby achieving the purpose of improving the material properties, such as increasing hardness, strength, toughness, or eliminating stress, etc. Aging treatment is usually carried out after the material has undergone solution treatment. Solution treatment dissolves alloying elements into the matrix metal to form a supersaturated solid solution, and then the material is cooled to room temperature. At this time, the performance of the material does not reach the optimal state. By heating the material in the aging furnace to a certain temperature and maintaining it for a period of time (aging treatment), the alloying elements in the supersaturated solid solution can precipitate to form strengthening phases, thereby significantly improving the mechanical properties of the material.

[0003] For example, an aging furnace for aluminum alloy profile production with the publication number CN216303937U includes a machine shell and a heat insulation lining installed in the inner cavity of the machine shell. The heat insulation lining divides the inner cavity of the machine shell into an equipment installation cavity and a heating cavity. The lower wall of the heating cavity is provided with a turntable for carrying aluminum alloy profiles. A distribution cavity communicating with the heating cavity is opened in the turntable. A third air delivery pipe communicating with the distribution cavity is fixedly installed on the turntable. A driving device for driving the third air delivery pipe to rotate is provided in the equipment installation cavity. A gas equalizing cover is fixedly installed on the side wall of the heating cavity. A fan for sucking the hot air inside the heating cavity and a burner for simultaneously delivering hot air to the gas equalizing cover and the distribution cavity are provided in the equipment installation cavity. In this utility model, by driving the rotation of the aluminum alloy profiles, the position of the profiles and the jet points is periodically changed, and at the same time, the bottom profiles are heated by using the distribution cavity, improving the uniformity of heat absorption of the profiles;

[0004] This aging furnace conducts heat circulation by sucking the hot air back in and reheating it through the fan during the heating process. However, since the heat absorption pipe is located in the middle of the upper end of its machine shell, when it blows air horizontally, the hot air can only be sucked away by the fan after passing through only half of the range inside the machine shell, resulting in uneven heat absorption in the horizontal range of the machine shell. To solve the above problems, an aging furnace for cable production is proposed. Content of the Utility Model

[0005] The purpose of the utility model is: to solve the above problems, and provide an aging furnace for cable production, including:

[0006] An aging furnace body, on one side of which a fixed seat is fixedly installed. A hot air blower is fixedly installed on the upper surface of the fixed seat. A hot air pipe is fixedly installed on the outer wall of the upper end of the aging furnace body. One side of the hot air pipe is fixedly connected to the output end of the hot air blower;

[0007] The first heat circulation block is fixedly installed on the left side of the inner wall of the aging furnace body. One end of the hot air pipe is fixedly connected to the input end of the first heat circulation block. A second heat circulation block is fixedly installed on the right side of the inner wall of the aging furnace body. A third heat circulation block is fixedly installed on the top of the inner wall of the aging furnace body. The first heat circulation block is in a "T" shape structure. The second heat circulation block is in a "U" shape structure. The third heat circulation block is in an "L" shape structure. The air outlet in the middle of the first heat circulation block and the air inlet at the upper end of the second heat circulation block are on the same horizontal line. The output end of the third heat circulation block and the air outlet at the upper end of the first heat circulation block are on the same vertical line.

[0008] Through the above technical solution, when the cable enters the inside of the aging furnace body, the hot air blower works to blow hot air into the hot air pipe. The hot air in the hot air pipe enters the inside of the first heat circulation block. On the one hand, the hot air entering the first heat circulation block enters the second heat circulation block through its horizontal outlet. On the other hand, it enters the lower left side of the aging furnace body through its vertical outlet. The hot air entering the second heat circulation block is discharged through its lower outlet and enters the lower right side of the aging furnace body. At this time, the hot air at the lower left and right sides of the aging furnace body meets at the lower middle of the aging furnace body and converges upward into the third heat circulation block. At this time, the cable is blown by hot air horizontally and vertically, making its heating uniform. At the same time, the hot air entering the third heat circulation block is discharged downward into the first heat circulation block, so as to recycle the hot air.

[0009] In a preferred embodiment, a slide rail is fixedly installed on the side of the aging furnace body away from the fixed seat. A moving tray is slidably connected to the top of the slide rail.

[0010] Through the above technical solution, the cable to be stress-relieved is placed on the upper surface of the moving tray, and the moving tray drives the cable to move along the slide rail and enter the inside of the aging furnace body.

[0011] In a preferred embodiment, a fixed block is fixedly installed on the front outer wall of the aging furnace body. A sealing door is slidably connected inside the fixed block.

[0012] In a preferred embodiment, a fixed frame is fixedly installed on one side of the upper surface of the aging furnace body. A rotating shaft is rotatably connected inside the fixed frame. A transmission disc is fixedly installed on the outer wall of the rotating shaft. A motor is fixedly installed on the upper surface of the aging furnace body. A transmission belt is arranged between the output shaft of the motor and the rotating shaft. A traction rope is wound around the outer wall of the transmission disc, and one end of the traction rope is fixedly installed on the top of the sealing door.

[0013] Through the above technical solution, the motor works to drive the rotating shaft to rotate clockwise. The rotating shaft drives the transmission disc to rotate clockwise, thereby driving the traction rope to pull up the sealing door. Conversely, the sealing door is closed.

[0014] In a preferred embodiment, a groove adapted to the sealing door is provided on the upper surface of one side of the movable tray.

[0015] In a preferred embodiment, an exhaust duct is fixedly installed on the outer wall at the rear side of the aging furnace body.

[0016] Through the above technical solution, after the stress of the cable is removed, the hot air in the aging furnace body is discharged through the exhaust duct.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effect of the present utility model is that the present utility model provides an aging furnace for cable production.

[0018] When the cable enters the interior of the aging furnace body, the hot air blower works to blow hot air into the hot air duct. The hot air in the hot air duct enters the first heat circulation block. On the one hand, the hot air entering the first heat circulation block enters the second heat circulation block through its horizontal outlet, and on the other hand, it enters the lower left end of the aging furnace body through its vertical outlet. The hot air entering the second heat circulation block is discharged through its lower outlet and enters the lower right end of the aging furnace body. At this time, the hot air at the lower left and right ends of the aging furnace body meets at the lower middle part of the aging furnace body and converges upward into the third heat circulation block. At this time, the cable is blown by hot air horizontally and vertically, making its heating uniform. At the same time, the hot air entering the third heat circulation block is discharged downward into the first heat circulation block, thereby recycling the hot air. BRIEF DESCRIPTION OF THE DRAWINGS
