[0002] The spinning process technology is to continuously extend the structure of the wheel rim part during the rolling process by continuous rotational movement and extrusion under specific pressure and temperature. While ensuring sufficient strength, the spinning wheel can greatly reduce the material thickness. Currently, the forging automobile wheel production line uses a cold spinning press. A mold is placed inside the spinning press in advance, and a six-axis robot automatically places the wheel on the mold, and then the spinning press performs the spinning action. During the spinning process, due to the metal extrusion effect, the wheel is prone to sticking to the mold and is difficult to detach normally, resulting in the wheel being unable to be taken out from the spinning press.

[0018] As Figure 1 , Figure 2 shown, the present utility model provides a device for automatically applying oil in the spinning process of an automobile wheel, including a box body 1 made of stainless steel, an oil spraying plate 3 and a high-leg stand 2. The box body 1 is fixed on the high-leg stand 2. One side surface of the box body 1 is an open surface. The bottom surface of the box body 1 has an oil discharge port 1-2. On the bottom surface inside the box body 1, there is a support column 4 for fixing the oil spraying plate 3 above the oil discharge port 1-2. The bottom surface of the oil spraying plate 3 is fixed on the support column 4. Six nozzles 7 communicating with the internal oil cavity of the oil spraying plate 3 are evenly distributed on the upper surface of the oil spraying plate 3. The nozzles 7 are arranged in a ring shape. The bottom surface of the oil spraying plate 3 has an oil spray pipe 5 communicating with the oil cavity. The oil spray pipe 5 extends outside the box body 1;

[0019] An oil discharge pipe 6 is connected to the oil discharge port 1-2. The oil discharge pipe 6 is located below the box body 1.

[0020] The bottom surface inside the box body 1 is a funnel-shaped structure 1-1 with a high outer edge and a low middle oil discharge port 1-2. A baffle and a soft curtain are arranged on the open surface of the box body 1.

[0021] When the above structure is in use, the oil spray pipe 5 is connected to an external oil spraying device, and the oil discharge pipe 6 is connected to a recovery device. The rim of the wheel is sent into the box body 1 from the open surface of the box body 1 by a robotic arm. The robotic arm keeps the wheel directly above the oil spraying plate 3. The valve in the oil spray pipe 5 is opened, and the external oil spraying device is started. The oil mist is evenly sprayed on the surface of the wheel rim through the nozzles 7. The soft curtain and the baffle play a role in reducing the oil mist from spraying out of the box body 1. After the operation is completed, the robotic arm takes out the wheel rim from the box body 1 and then sends the wheel rim into a spinning press for processing. The excess oil liquid sprayed out from the nozzles 7 flows into the oil discharge pipe 6 through the oil discharge port 1-2 on the bottom surface of the box body 1 with the funnel-shaped structure 1-1. By opening the valve in the oil discharge pipe 6, the excess oil liquid can be collected into the recovery device.

[0022] In the above structure, in order to prevent the oil mist from diffusing outside the box body 1, a baffle and a soft curtain are provided. However, the soft curtain is likely to rub or entangle with the robotic arm when the robotic arm enters and exits the box body 1, and the soft curtain is likely to be damaged after long-term use. The oil mist adhered to the soft curtain is also not easy to clean, which causes a certain degree of pollution to the workpiece. To solve this problem, on the basis of the above structure, an improvement is made. The structure of the baffle and the soft curtain is removed and replaced with a fence, as Figure 3 , Figure 4As shown in the figure, on the bottom surface inside the box body 1, there is a circular-sectioned retaining wall 8, and the oil spraying plate 3 is located inside the retaining wall 8. During use, the robotic arm places the wheel rim in the area inside the retaining wall 8, and makes the outer edge of the workpiece contact the inner wall of the retaining wall 8. The excess oil mist sprayed will splash onto the inner wall of the retaining wall 8. At the same time, since the workpiece contacts the inner wall of the retaining wall 8, the oil mist cannot overflow from above the retaining wall. The oil mist splashed onto the inner wall of the retaining wall 8 then slides down along the inner wall of the retaining wall 8 to the bottom surface of the funnel-shaped structure 1-1 of the box body 1 and flows out from the oil drain port 1-2.

[0023] On the bottom surface inside the box body 1, there is an annular plug-in plate 9. The lower edge of the retaining wall 8 is plugged into the annular plug-in groove 9-1 on the annular plug-in plate 9, and the lower edge of the retaining wall 8 and the annular plug-in plate 9 are fixed by a set screw passing through the side surface of the annular plug-in plate 9. By using the plug-in connection method between the retaining wall 8 and the annular plug-in plate 9, the retaining wall 8 is detachably connected inside the box body 1, which is convenient for regularly replacing or cleaning the retaining wall 8.

[0024] The longitudinal section of the retaining wall is an inverted trapezoid, and a rubber protective layer is covered on the inner side wall of the retaining wall. The design of the inverted trapezoid section enables the retaining wall 8 to be applicable to workpieces with various outer diameter specifications. The rubber protective layer can prevent the outer edge of the workpiece from making hard contact with the inner wall of the retaining wall 8, and at the same time keep the contact surface sealed to prevent the oil mist from overflowing from the gap between the workpiece and the inner wall of the retaining wall 8.

[0025] The above has described the embodiments of the present invention in detail, but the content described is only the preferred embodiments of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
