[0002] Aging treatment refers to a heat treatment process in which alloy workpieces, after solution treatment, cold plastic deformation, casting, or forging, are placed at a high temperature or at room temperature to maintain their properties, shape, and size from changes over time.

[0003] As a type of heat treatment equipment, the heat treatment aging furnace has a relatively mature overall structure, including the furnace body, insulation layer, heating components, and hot air circulation components. It uses a circulating fan to drive the heat circulation inside the equipment, so that the metal parts are heated. However, there are some functional deficiencies in actual use, and there is room for improvement. For example, most furnaces currently use a single fan to circulate hot air, but the number of metal parts inside the furnace is large and the stacking layers are high, resulting in low hot air circulation efficiency, large differences in local heating efficiency, and difficulty in controlling deformation. It also lacks the function of multi-position circulating temperature control.

[0009] As a further technical solution of this utility model, the blower cavity penetrates the outer shell of the furnace body, the inner heat insulation layer and extends into the interior of the outer shell of the furnace body, and the bottom end of the second impeller is higher than the top end of the heating wire.

[0010] As a further technical solution of this utility model, the heating wires are arranged at equal intervals, and the first drive motor, the second drive motor, the heating wires, and the control box are electrically connected.

[0025] Example: Please refer to Figure 1-4 A heat treatment aging furnace for controlling deformation includes a furnace shell 1, an inner insulation layer 2 fixedly connected to the inner wall of the furnace shell 1, four sets of first wheel grooves 15 provided at the bottom inside the furnace shell 1, a first wheel track 16 fixedly connected to the bottom inside the first wheel grooves 15, a control box 17 fixedly connected to the left side of the front end of the furnace shell 1, furnace door limiting posts 21 fixedly connected to the front and rear ends of the left and right sides of the furnace shell 1 respectively, a support beam 22 fixedly connected between the top ends of the two sets of furnace door limiting posts 21, two sets of winches 23 installed at the top of the support beam 22, steel cables 24 wound around the outside of the winches 23, a sealed furnace door 25 provided between the two sets of furnace door limiting posts 21, and a heating component with multi-channel temperature control provided at the top of the furnace shell 1.

[0026] Please see Figure 1-4 A heat treatment aging furnace for controlling deformation also includes a heating assembly, which includes multiple sets of air ducts 7. The multiple sets of air ducts 7 are fixedly connected to the top of the furnace shell 1. Air guide pipes 6 are fixedly connected to the front and rear ends of the air ducts 7.

A first impeller 5 is fixedly connected to the output end of the first drive motor 4. A second drive motor 8 is installed at the top of the air duct 7. A second impeller 9 is fixedly connected to the output end of the second drive motor 8. Multiple sets of heating wires 10 are installed between the front and rear ends inside the air duct 7.

[0027] The suction chamber 3 passes through the furnace shell 1 and the inner insulation layer 2 and extends into the interior of the furnace shell 1. The suction chamber 3, the air guide pipe 6, and the blower chamber 7 are connected. The blower chamber 7 passes through the furnace shell 1 and the inner insulation layer 2 and extends into the interior of the furnace shell 1. The bottom of the second impeller 9 is higher than the top of the heating wire 10. The heating wires 10 are arranged at equal intervals. The first drive motor 4, the second drive motor 8, the heating wires 10, and the control box 17 are electrically connected. Multi-position circulating heating provides uniform heating and makes it easier to control the amount of deformation.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the second drive motor 8 on the blower chamber 7 drives the second impeller 9 to rotate at high speed and blow air downwards, blowing the air heated by the heating wire 10 towards the metal parts below. At the same time, the first drive motor 4 on the suction chamber 3 drives the first impeller 5 to rotate at high speed to generate negative pressure, drawing in the hot air inside the furnace and sending it back to the blower chamber 7 through the air guide pipe 6. Multi-position circulating air supply can make the furnace body heat up quickly and evenly, making it easy to control the amount of deformation. The first drive motor 4, the second drive motor 8, the heating wire 10, and the control box 17 are electrically connected. This technology is existing technology and will not be described in detail.

[0029] A fixing plate 11 is fixedly connected to the outer side of the air duct 6. Two sets of handles 12 are fixedly connected to the outer side of the fixing plate 11. Mounting bolts 13 are inserted into the four corners of the outer side of the fixing plate 11. Multiple sets of electric heating tubes 14 are fixedly connected to the inner side of the fixing plate 11. The mounting bolts 13 pass through the fixing plate 11 and extend into the interior of the air duct 6. The electric heating tubes 14 and the control box 17 are electrically connected. Secondary heating improves heating efficiency.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, the multiple sets of electric heating tubes 14 on the fixed plate 11 perform secondary heating on the return air, which can improve the air heating efficiency. The handle 12 and the mounting bolts 13 facilitate the disassembly and assembly of the fixed plate 11. The electric heating tubes 14 and the control box 17 are electrically connected. This technology is existing technology, so it will not be described in detail.

[0031] The left and right sides of the furnace shell 1 are respectively fixedly connected to the trolley support plate 18. The top of the trolley support plate 18 is provided with four sets of second trolley wheel grooves 19. The bottom of the second trolley wheel groove 19 is fixedly connected to the second trolley track 20. The positions and dimensions of the first trolley wheel groove 15 and the second trolley wheel groove 19 correspond one to one. The first trolley track 16 and the second trolley track 20 have the same specifications, and the bidirectional entry and exit has higher production efficiency.

[0032] Specifically, such as Figure 1 and Figure 4As shown, the trolley support plates 18 on both sides are used to support the trolley, so that it can move along the second trolley track 20 in the second trolley wheel groove 19. The two sets of trolley support plates 18, together with the two sets of sealed furnace doors 25, can move in and out simultaneously on both sides, which can improve production efficiency and eliminate the time of repeated heating, making it more energy-saving and environmentally friendly.

[0033] Working Principle: In use, the metal parts to be heat-treated are first stacked on a trolley, which is then pushed into the furnace for aging treatment. The second drive motor 8 on the blower chamber 7 drives the second impeller 9 to rotate at high speed, blowing downwards air heated by the heating wire 10 towards the metal parts below. Simultaneously, the first drive motor 4 on the suction chamber 3 drives the first impeller 5 to rotate at high speed, generating negative pressure to draw in hot air from the furnace and return it to the blower chamber 7 through the air guide pipe 6. This multi-position circulating air supply allows for rapid and uniform heating inside the furnace, facilitating control of deformation. When the hot air from the furnace is returned to the blower chamber 7 through the air guide pipe 6, multiple sets of heating elements 14 on the fixing plate 11 provide secondary heating to the returning air, improving heating efficiency. The handle 12 and mounting bolts 13 facilitate the assembly and disassembly of the fixing plate 11. The winch 23 pulls up or lowers the sealed furnace door 25 via the steel cable 24 to facilitate the entry of the trolley. The trolley support plates 18 on both sides support the trolley and allow it to move along the second trolley track 20 in the second wheel groove 19. The two sets of trolley support plates 18, together with the two sets of sealed furnace doors 25, allow the trolley to enter and exit simultaneously, which can improve production efficiency and eliminate the time required for repeated heating, making it more energy-efficient and environmentally friendly.
