Technical Field
[0001] The utility model relates to the technical field of automobile wheel cover processing, in particular to a trimming and forming device for automobile wheel cover after hot pressing forming. Background Art
[0002] Automobile wheel covers are installed on the outer side of automobile hubs to prevent water and rust on the screws on the hubs. The most common technology is to manufacture automobile wheel covers by hot pressing. After the hot pressing process is completed, they need to be trimmed and polished to remove surface burrs. In the prior art, automobile wheel covers are often placed directly on a workbench for trimming and polishing. However, a large amount of debris will be splashed during polishing. These debris splashing everywhere not only affects the environmental sanitation of the working area, but also may pose a health threat to the staff. For this reason, we propose a trimming and molding device for automobile wheel covers after hot pressing. Utility Model Content
[0003] The utility model aims to solve the shortcomings in the prior art and proposes a trimming and forming device for a car wheel cover after hot pressing forming.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A trimming and forming device after hot-pressing forming of an automobile wheel cover comprises a hollow cylindrical column, a plurality of hollow plates are fixedly connected inside the column, each of the hollow plates is sealingly and slidably connected to a curved plate, a hollow inner column is fixedly connected to the middle of the column, and an upper tube is connected to the inner column and each of the hollow plates; a base is fixedly connected to the bottom of the inner column, a plurality of telescopic tubes are fixedly connected to the base, a lifting ring is fixedly connected to the upper ends of the plurality of telescopic tubes, a retaining ring is fixedly connected to the lifting ring, and the retaining ring has a flexible barrel-shaped structure; when the curved plate is squeezed and moves into the hollow plate, the air squeezed into the hollow plate enters the telescopic tube through the upper tube, the telescopic tube expands and stretches to push the lifting ring upward, and the retaining ring is pulled upward to complete the shielding and covering of the column.
[0006] The utility model has the following beneficial effects:
[0007] When the device of the utility model is in use, the wheel cover to be trimmed is sleeved on the column, and then the wheel cover is pressed downward, and the wheel cover squeezes the arc plate to move toward the inside of the column, so that the air in the hollow plate is squeezed into the inside of the telescopic tube through the upper tube, thereby driving the lifting ring to move upward. During this process, the retaining ring moves upward accordingly until it covers the wheel cover, and then the wheel cover can be trimmed and polished. At this time, most of the flying debris can be blocked inside the retaining ring, so as to avoid splashing everywhere and affecting the hygiene and health of the staff.

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0013] Reference Figures 1 to 3 The utility model provides a trimming and forming device for a car wheel cover after hot pressing forming, comprising a hollow cylindrical column 1, a plurality of hollow plates 9 are fixedly connected inside the column 1, each hollow plate 9 is sealed and slidably connected to a curved plate 2, a hollow inner column 10 is fixedly connected to the middle of the column 1, and an upper tube 11 is connected to the inner column 10 and each hollow plate 9; when using the device of the utility model, the wheel cover to be trimmed is placed on the column 1, and the outer diameter of the column 1 is smaller than the inner diameter of the wheel cover; pressing the wheel cover downward can make the outer wall of the curved plate 2 abut against the inner circle of the wheel cover, so as to complete the fixation of the wheel cover, and wheel covers of different sizes can be fixed by the above structure.
[0014] The bottom of the inner column 10 is fixedly connected with a base 6, and a plurality of telescopic tubes 8 are fixedly connected to the base 6. The upper ends of the plurality of telescopic tubes 8 are fixedly connected with a lifting ring 7, and a retaining ring 14 is fixedly connected to the lifting ring 7. The retaining ring 14 is a flexible barrel-shaped structure. When the arc plate 2 is squeezed and moves into the hollow plate 9, the air in the hollow plate 9 is squeezed into the telescopic tube 8 through the upper tube 11. The telescopic tube 8 expands and stretches to push the lifting ring 7 upward, and the retaining ring 14 moves upward to cover the column 1. After the wheel cover and the outer wall of the arc plate 2 are against each other, the wheel cover is pressed continuously, so that the wheel cover continues to move downward. At this time, the arc plate 2 is squeezed and moves inward, so that the air in the hollow plate 9 is squeezed into the inside of the telescopic tube 8 through the upper tube 11, thereby driving the lifting ring 7 to move upward until the retaining ring 14 covers the wheel cover. At this time, trimming and grinding the wheel cover can block most of the splashing debris inside the retaining ring 14, avoiding splashing everywhere to affect the hygiene and the health of the staff.
[0015] Reference Figure 2-3 The end face of the arc plate 2 close to the outer wall of the column 1 is an arc structure. When the arc plate 2 moves outward to the extreme position, the upper outer wall of the arc plate 2 does not exceed the circumferential surface of the column 1, that is, the upper end of the arc plate 2 is always in the internal space of the column 1, avoiding the interference between the upper wall of the arc plate 2 and the wheel cover.
[0016] Reference Figure 2-3 The arc plate 2 is provided with a plate groove 3, in which a friction plate 4 is sealed and slidably connected, and a telescopic tube 8 is fixedly connected to the bottom of the inner column 10, and the telescopic tube 8 is connected to each plate groove 3 through a pipeline. The outer wall of the arc plate 2 is a smooth curved surface, ensuring that the arc plate 2 can be smoothly squeezed toward the middle when the wheel cover squeezes the arc plate 2. The friction plate 4 is a component that can generate a large friction force with the wheel cover, and can prevent the wheel cover from rotating and affecting the trimming when trimming and grinding are performed;
[0017] The inner column 10 is internally sealed and slidably connected with a sealing rod 12. The sealing rod 12 moves downward to squeeze the telescopic tube 8, which can squeeze the air in the telescopic tube 8 into the plate groove 3, so that the friction plate 4 contacts the wheel cover to form a larger friction force.
[0018] The extreme point of the movement of the friction plate 4 out of the plate groove 3 is no more than 2 mm from the outer edge of the plate groove 3, so as to avoid damage to the wheel cover caused by excessive squeezing force; the outer layer of the friction plate 4 is made of rubber, which can provide greater friction.
[0019] Reference Figure 3 A spring 17 is fixedly connected to the inside of the hollow plate 9, and the spring 17 is fixedly connected to the arc plate 2. The arc plate 2 and the hollow plate 9 maintain a sealed sliding connection. There is a large friction between the two. The spring 17 can provide elastic force to the arc plate 2 to move outward. After the wheel cover is removed, the elastic force of the spring can restore the arc plate 2 and the entire device to their initial state.
[0020] The lower wall of the column 1 is fixedly connected with a support plate 5, which is flush with the upper wall of the base 6. The retaining ring 14 passes through the gap between the support plate 5 and the upper wall of the base 6. The debris and dust splashed by trimming and grinding are more accumulated on the support plate 5, and being flush with the base 6 can facilitate cleaning and maintenance after grinding.
[0021] A storage ring 15 is fixedly connected inside the base 6, and the lower end of the retaining ring 14 is rolled up on the storage ring 15. A storage rod 16 is provided inside the base 6, and the storage rod 16 includes a columnar friction roller, which abuts against the storage ring 15. A torsion spring is provided at the center of the friction roller. The torsion spring has the tendency to drive the friction roller to rotate and store the retaining ring 14 into the storage ring. When the device of the utility model is not in use, the torsion spring acts to make the retaining ring 14 be stored on the storage ring 15, thereby preventing the inside of the base 6 from being too messy.
[0022] When the sealing rod 12 moves downward until it contacts the telescopic tube 8, it blocks the interface between the upper tube 11 and the inner column 10. At this time, the arc plate 2 cannot continue to slide relative to the hollow plate 9, ensuring that the position of the wheel cover remains stable and avoiding displacement of the wheel cover during the grinding process.
[0023] To sum up: in the utility model, when the wheel cover needs to be polished, the wheel cover is placed on the column 1, the inner diameter of the wheel cover is sleeved on the outer wall of the column 1, the wheel cover is pressed downward until the retaining ring 14 moves to be higher than the wheel cover, and then the sealing rod 12 is pressed downward to complete the locking of the wheel cover. At this time, the trimming and grinding operation can be started. The dust and debris splashed by the trimming and grinding can be more blocked inside the retaining ring 14, avoiding the splashing of debris and dust to affect the health of the staff.
[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
