Description

Technical Field

[0001] This utility model relates to the field of preheating furnaces, and in particular to a circular spinning preheating furnace. Background Technology

[0002] A spinning preheating furnace is a heat treatment device used for aluminum alloy automotive wheel hub blanks before spinning. It mainly consists of a fan, furnace body, air guide system, furnace door, internal steel frame, furnace platform, furnace frame, robot, support rollers, drive mechanism, combustion system, protective facilities, and exhaust system. The main features of the spinning preheating furnace include a compact structure, small footprint, and the elimination of chain and roller drives, thus reducing operating and maintenance costs.

[0003] The utility model patent with publication number CN 212842867 U discloses an aluminum alloy wheel hub pressing and spinning preheating furnace. Through a temperature sensor installed on the inner wall of the insulation layer, the operator can detect the temperature inside the preheating furnace and adjust it with an intelligent temperature controller to avoid the phenomenon that the wheel hub cannot be formed when the temperature inside the preheating furnace is too high and explodes, or that the wheel hub cannot reach the plasticity required for pressing and spinning when the temperature inside the preheating furnace is too low.

[0004] However, the method of hanging the wheel hub for heating has poor stability. The wheel hub will shake in the preheating furnace and there is a risk of falling, resulting in a low safety factor. At the same time, the hook will also cause some wear and tear on the wheel hub, affecting the surface quality of the wheel hub and making it impractical. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 As shown in Figure 4, the circular spinning preheating furnace provided in this embodiment includes a device body 1, which contains a furnace body 2, a lifting platform 4, a connecting component 7, and a rotating component 9. The furnace body 2 has a base 21 at its lower end, a heating layer 22 on its inner wall, and an inner slide rail 23 at its lower end. A furnace door 3 is hinged to the front end of the furnace body 2. The lifting platform 4 is located at the lower front end of the furnace body 2 and has an outer slide rail 41. Guide rods 5 slide on the inner slide rail 23 and the outer slide rail 41. A workbench 6 is fixed on the guide rods 5. The connecting component 7 is located on the workbench 6 and has an arc-shaped frame 8 installed on its top. The rotating component 9 is located inside the arc-shaped frame 8.

[0023] Preferably, the connecting component 7 includes an inner support 71, which has several sets of positioning posts 72 and a connecting hole 73 in the middle. An outer support 76 is provided on the outside of the inner support 71. Four sets of arc-shaped frames 8 are provided and placed on the inner support 71 respectively. The two sides of the arc-shaped frames 8 are respectively attached to the outer support 76. The arc-shaped frames 8 have positioning holes 81 and inner grooves 82. The positioning holes 81 are correspondingly fitted on the positioning posts 72. A connecting bolt 74 passes through the inner groove 82 and the connecting hole 73, and a nut 75 is screwed to the lower end of the connecting bolt 74.

[0024] The arc frame 8 is supported by the inner bracket 71 and the outer bracket 76, and positioned by the positioning column 72 and the positioning hole 81. The arc frame 8 is fixed to the upper end of the bracket by the connecting bolt 74, thus enabling quick assembly and disassembly of the arc frame 8. The structure is simple and easy to operate. Only one set of connecting bolts 74 is needed to fix it, saving installation and disassembly time and facilitating later maintenance and replacement.

[0025] Preferably, the rotating assembly 9 includes a driving roller 91 and a driven roller 92, with two sets of driving roller 91 and driven roller 92 respectively. A connecting shaft 93 is provided between the driving roller 91. The front ends of the two sets of connecting shafts 93 are respectively provided with a first gear 94 and a second gear 95. A motor 96 is provided on one side of the driving roller 91. A third gear 97 is connected to the driving end of the motor 96. Hinges 83 are provided on both sides of the arc frame 8. The driving roller 91 and driven roller 92 are rotatably mounted on the inner side of the two hinges 83 respectively. The third gear 97 meshes with the first gear 94 and the second gear 95 at the same time.

[0026] The electric motor 96 drives the third gear 97 to rotate, which in turn drives the first gear 94 and the second gear 95 to rotate. The two sets of gears drive the connecting shaft 93 and the driving roller 91 to rotate. The driving roller 91 and the driven roller 92 work together to drive the hub to rotate, thereby enabling rotational control of the spinning hub. This facilitates comprehensive and uniform preheating of the hub, preventing uneven heating of partially obscured areas during heating and improving the practicality of the device.

[0027] The working principle and process of this utility model are as follows: During use, the workbench 6 is pulled out of the furnace body 2 via the guide rod 5, inner slide rail 23, and outer slide rail 41. The wheel hub to be processed is placed on the driving roller 91 and driven roller 92. Then, the workbench 6 is pushed back into the furnace body 2 and the furnace door 3 is closed. The wheel hub is preheated through the heating layer 22. During this process, the motor 96 should be turned on. The motor 96 drives the third gear 97 to rotate, which in turn drives the first gear 94 and the second gear 95 to rotate. The two sets of gears are connected... The shaft 93 and the drive roller 91 rotate, and the drive roller 91 and the driven roller 92 work together to drive the hub to rotate, thereby realizing the rotation control of the spinning hub. This facilitates a comprehensive and uniform preheating operation of the hub, improving the preheating efficiency and subsequent spinning quality. When the rotating component 9 needs to be replaced or maintained, the connecting bolt 74 can be removed from the connecting hole 73 and the inner groove 82, and then the arc frame 8 can be directly removed from the positioning post 72. The operation is simple and convenient, with only one set of bolts needing to be removed, saving maintenance time.
