[0002] The wheel hub is an important component of the tire. It is used to support the wheel and can bear the weight of the vehicle. There are many types of wheel hubs depending on the diameter, width, molding method and material.

[0003] In the current existing technology, in order to improve the utilization efficiency of fuel and reduce the gravity of the vehicle, people will choose magnesium alloy to manufacture wheel hubs. When producing magnesium alloy wheel hubs, it is necessary to cut the magnesium alloy rods into blanks of corresponding sizes, then heat the blanks, and then put them into the corresponding forming molds. The blanks are forged into corresponding shapes by means of hydraulic forging machines, and then the heating needs to be repeated many times, and the forging of the wheel hub is completed by using multiple forming molds with different precisions. The heating of the wheel hub blank is generally completed by a heating furnace, and the heating furnace is equipped with a mesh belt to convey the wheel hub.

By hooking the hub blank, it is convenient to turn it over. When the grabbing seat 15 moves downward, the rack 42 will first contact the mesh belt body 12, and under pressure, the rack 42 will push the gear 41 to rotate, thereby driving the hook arm 32 to rotate counterclockwise to open, playing a role of blocking.

[0026] Further, such as Figure 4 As shown, a plurality of elastic sheets 51 are fixedly connected to the surface of the flip wheel 16; the plurality of elastic sheets 51 are fixedly connected to the flip wheel 16 in a surrounding array; an elastic ring 52 is fixedly connected to one end of the elastic sheet 51 away from the flip wheel 16; when in use, the elastic ring 52 is supported by the plurality of elastic sheets 51 to form an elastic structure, and after the flip wheel 16 contacts the wheel hub blank, it can increase the contact area with the wheel hub blank and improve the friction, thereby facilitating flipping and reducing the occurrence of scratches.

[0027] Further, such as Figure 2 As shown, guide plates 6 are fixedly connected to both sides of the inner wall of the flip box 13; the two guide plates 6 are designed in a trapezoidal structure; when in use, when the wheel hub enters the flip box 13, the guide plates 6 on both sides can be used to guide and position the wheel hub, so that the wheel hub is in the center of the mesh belt body 12, so as to facilitate the range of the flip wheel 16 and reduce the skewness of the wheel hub blank during the flipping process.

[0028] Further, such as Figure 4 As shown, the end of the hook arm 32 away from the rotating shaft 31 is rotatably connected to the rotating wheel 7; when in use, the rotating wheel 7 installed at the end of the hook arm 32 can reduce the friction between the contact position of the hook arm 32 and the hub blank, thereby reducing the scratches on the surface of the hub blank and reducing the wear of the hook arm 32.

[0029] Working principle: when in use, the staff places the wheel hub blank on the top of the mesh belt body 12, and needs to place the wheel hub blank on the side of the stop wheel 17, and then relies on the mesh belt body 12 to send it into the heating furnace body 11 for heating, and then moves it to the flip box 13, and then starts the hydraulic cylinder 14, the hydraulic cylinder 14 pushes the grab seat 15 to move down, and then the side flip wheel 16 of the grab seat 15 contacts the wheel hub blank, and the other side of the wheel hub blank contacts the stop wheel 17, the mesh belt body 12 continues to push the wheel hub blank, and at the same time the hydraulic cylinder 14 contracts and pulls the grab seat 15, squeezing and grabbing the edge of the wheel hub blank, so as to flip the wheel hub blank, and then enter another heating The furnace body 11 is heated, so that the hub blank can be heated evenly, thereby reducing the situation of repeatedly entering the heating furnace body 11 or prolonging the heating time. A separate turning box 13 is set to reduce the temperature of this area. There is no heating element in the turning box 13.

When the wheel hub blank is turned over and is in a vertical state, the friction between the turning wheel 16 and the surface of the wheel hub blank is small. By hooking the wheel hub blank, it is convenient to turn it over. When the grabbing seat 15 moves down, the rack 42 will first contact the mesh belt body 12. Under the pressure, the rack 42 will push the gear 41 to rotate, thereby driving the hook arm 32 to rotate counterclockwise to open, playing a role of blocking. A plurality of elastic sheets 51 are provided to support the elastic ring 52 to form an elastic structure. After the wheel 16 contacts the wheel hub blank, it can increase the contact area between the wheel hub blank and the wheel hub blank, thereby increasing the friction force, making it easier to flip over and reducing the occurrence of scratches. When the wheel hub enters the flipping box 13, the guide plates 6 on both sides can be used to guide and position the wheel hub, so that the wheel hub is in the center position of the mesh belt body 12, so as to facilitate the range of the flipping wheel 16 and reduce the skewness of the wheel hub blank during the flipping process. By relying on the flipping wheel 16 installed at the end of the hook arm 32, the friction force at the contact position between the hook arm 32 and the wheel hub blank can be reduced, thereby reducing the generation of pulleys on the surface of the wheel hub blank and reducing the wear of the hook arm 32.
