Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a wheel pressing device. Background Technology

[0002] In the automotive manufacturing and parts processing industry, the pressing of wheel rims and spokes is a key process to ensure the overall structural strength and safety of the wheel. Its pressing accuracy directly affects the dynamic balance performance of the wheel and the driving stability of the whole vehicle.

[0003] Existing wheel pressing devices mostly use a single center hole positioning or a simple template alignment method, which has the following shortcomings:

[0004] Insufficient positioning accuracy: Due to the lack of specialized rim and spoke positioning structures and precise guide components, the upper and lower dies are prone to misalignment during the press-fitting process, which leads to reduced assembly accuracy of the rim and spokes, and even problems such as workpiece deformation and press-fitting misalignment, seriously affecting the product qualification rate.

[0005] Low level of automation: The clamping and fixing of workpieces mostly rely on manual operation, which is not only labor-intensive, but also prone to human error due to uneven operating force or positioning deviation; after pressing, the workpieces need to be manually moved, which further reduces production efficiency.

[0006] Poor adaptability: For wheels of different specifications, the entire set of molds needs to be changed frequently to meet the pressing requirements, which not only increases the cost of equipment investment, but also affects the continuity of production due to the long time spent on mold changing and adjustment; at the same time, the resetting of pressing parts mostly depends on manual intervention, which is cumbersome and prone to incomplete resetting.

[0007] The aforementioned problems make it difficult for existing pressing devices to meet the demands of large-scale, high-precision production in terms of production efficiency, product quality, and labor cost control. Therefore, there is an urgent need for a wheel pressing device that can improve positioning accuracy, automation level, and adaptability. Utility Model Content

Detailed Implementation

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] Example

[0021] Please refer to the accompanying drawings in the specification. In this embodiment of the utility model, the wheel pressing device includes an upper mold assembly and a lower mold assembly:

[0022] The upper mold assembly includes an upper template 1, an upper positioning 2 is provided at the bottom of the upper template 1, an upper mold 3 is provided inside the upper positioning 2, and the upper mold 3 is fixedly provided at the bottom of the upper template 1.

[0023] The lower mold assembly includes a lower base 4, with a lower template 5 fixedly connected to the top of the lower base 4. A lower fixing plate 6 is provided at the top of the lower template 5. Guide posts 17 are provided on both sides of the lower template 5. A guide sleeve 19 for use with the guide posts 17 is provided at the bottom of the upper template 1. An ejector rod 18 is provided at the bottom of the lower fixing plate 6, with the lower end of the ejector rod 18 penetrating through the top of the lower base 4 and the lower template 5. A slider 7 is provided at the top of the lower fixing plate 6. A spring seat 8 is provided on the side of the slider 7 above the lower fixing plate 6. A hydraulic cylinder 9 is mounted on the lower base 4. A hydraulic cylinder seat 10 is provided at the bottom of the hydraulic cylinder 9. The hydraulic cylinder seat 10 is movably mounted on the lower base 4. A cone 11 is fixedly connected to the piston rod of the hydraulic cylinder 9. The slider 7 is provided on the outer side of the cone 11, and the cone 11 and the slider 7 are slidably connected. A groove 12 is provided on the outer side of the upper end of the slider 7.

[0024] The lower template 5 is provided with a connector 13, which passes through the slider 7. The connector 13 at the top of the slider 7 is provided with a heightening seat 14, and the heightening seat 14 is provided with an adjusting ring 15. The top of the adjusting ring 15 is provided with a washer 16.

[0025] The bottom end of the ejector rod 18 is fixedly connected to the cylinder seat 10.

[0026] The bottom end of the upper positioning 2 is provided with a pressure rod 20, and the bottom end of the pressure rod 20 is provided with a pressure ring 21 that is used in conjunction with the groove 12.

[0027] The position where the slider 7 contacts the cone 11 is an inclined plane, and the cone 11 and the slider 7 are slidably connected through the inclined plane.

[0028] The spring seat 8 is provided with a spring 22 inside. One end of the spring 22 is connected to the spring seat 8, and the other end of the spring 22 is connected to the slider 7.

[0029] Working principle: The upper mold assembly and the lower mold assembly are separated. Then, a robotic arm (which is existing technology and purchased from the market) is used to place the spokes onto the top of the washer. Next, the rim is placed onto the slider. The inner side of the slider 7 contacts the cone 11 through the inclined surface, and the outer side is provided with a groove 12. During pressing, the hydraulic cylinder 9 pushes the cone 11 downward, and the inclined surface forces the slider 7 to expand outward in the horizontal direction. The groove 12 is in close contact with the inner hole of the wheel and applies lateral force, which, together with the vertical pressure of the upper mold, completes the interference fit. During resetting, the cone 11 moves upward, and the spring 22 pulls the slider 7 to retract inward, releasing the rim.

[0030] In summary, this utility model, through the guide post and guide sleeve cooperation structure and the rim and spoke positioning structure, utilizes the precise guidance and dedicated positioning structure of the guide post and guide sleeve to eliminate the alignment deviation between the upper and lower mold components, making the wheel press-fitting positioning more accurate and stable, thereby improving press-fitting precision. The hydraulic cylinder drives the cone to automatically clamp the workpiece, replacing manual fixing and reducing human error. The ejector rod and hydraulic cylinder seat work together to automatically eject the workpiece after press-fitting, reducing manual handling. The combination design of the adjusting ring and the heightening seat allows for adaptation to different wheel specifications without replacing the entire mold set; the spring enables automatic slider reset, eliminating the need for frequent manual adjustment of the mold and reset components, thus improving production efficiency and press-fitting quality while saving manpower.

[0031] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
