Abstract
Description
Technical Field
[0001] This utility model relates to a tooling for an automobile sunroof, specifically a shaping device for automobile sunroof glass. Background Technology
[0002] A car sunroof is installed on the roof of the vehicle, which can effectively allow air circulation inside the car and increase the intake of fresh air. At the same time, a car sunroof can also expand the field of vision and meet the shooting needs of mobile photography and videography.
[0003] As a crucial sub-component of the automotive sunroof, the contour of the upper surface of the glass assembly is of paramount importance. Excessive contour deviation not only affects the assembly of the sunroof assembly but also leads to discrepancies between the glass and the theoretical height of the body at the installation site, resulting in aesthetically unappealing quality defects. After the glass assembly is edged, especially during the process from demolding to complete cooling and curing of the PU (polyurethane), the contour of its upper surface undergoes significant changes. Therefore, the glass assembly requires edge-wrapping and shaping processes before installation onto the sunroof.
[0004] Glass Edge Wrapping Process: A standard tempered glass panel for a sunroof, due to its smooth outer surface and lack of special structure, cannot be fixed to the sunroof frame except through adhesive bonding. Furthermore, the lack of a special structure makes it difficult to fit the glass with surrounding components. Even with adhesive bonding, tempered glass still cannot meet the light requirements of a car sunroof. Therefore, polyurethane (PU) edge wrapping (plastic coating) is applied to the tempered glass and the embedded iron parts around it. This involves placing iron parts around the inner surface of the tempered glass, which is then placed in a mold. Molten polyurethane is used to fix the iron parts to the tempered glass. Current edge wrapping processes have the following drawbacks: During the process from the glass assembly's demolding to the complete cooling and solidification of the PU, the contour of the glass assembly's upper surface changes significantly as the polyurethane cools from a high-temperature liquid state to a room-temperature solid state. This results in the glass's contour not meeting requirements (mismatch with the car body's outer surface). This can only be resolved through reshaping.
[0005] Currently, glass measuring and shaping equipment typically features a raised perimeter and a recessed center, making it difficult for workers to place the glass at the bottom center of the equipment without scratching it. This type of equipment is labor-intensive, and the glass itself can easily cause injury. Therefore, inventing a shaping device for automotive sunroof glass would be highly beneficial. Summary of the Invention
[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a shaping device for automotive sunroof glass that can conveniently shape the glass to meet the quality and aesthetic requirements of automotive sunroof glass.
[0007] To solve the above problems, the technical solution of this utility model is as follows: It includes a base plate (1), a gantry frame (2) is movably mounted on the base plate (1), an upper shaping mechanism (3) is mounted on the gantry frame (2), a lower shaping mechanism (5) is mounted on the base plate (1) at a position corresponding to the upper shaping mechanism (3), and a movable frame (4) is provided at the middle position of the gantry frame (2). The upper shaping mechanism (3) includes an upper shaping fixing frame (36), an upper shaping cylinder (37) is fixed on the upper shaping fixing frame (36), and an upper shaping head (38) is fixed on the output shaft of the upper shaping cylinder (37); the lower shaping mechanism (5) includes a lower shaping fixing frame (39), a lower shaping head (40) is fixed on the lower shaping fixing frame (39), a lower shaping support rod (41) is connected to the bottom of the lower shaping head (40), and the lower shaping support rod (41) is connected to the output shaft of the lower shaping cylinder (42). The bottom of the lower shaping support rod (41) is provided with a lower shaping support rod wedge surface (43), the output shaft of the lower shaping cylinder (42) is connected to the lower shaping wedge block (44), and the wedge surface of the lower shaping wedge block (44) meshes with the wedge surface of the lower shaping support rod (43).
[0008] This invention can reshape glass whose upper surface contours can change significantly, ensuring the quality of the glass's curvature and reducing the labor intensity of workers. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings;
[0015] like Figure 1 , Figure 2 As shown, this utility model includes a base plate (1), a gantry frame (2) movably mounted on the base plate (1), an upper shaping mechanism (3) mounted on the gantry frame (2), a lower shaping mechanism (5) mounted on the base plate (1) at a position corresponding to the upper shaping mechanism (3), and a movable frame (4) provided at the middle position of the gantry frame (2). Figure 3 As shown, the upper shaping mechanism (3) includes an upper shaping fixing frame (36), an upper shaping cylinder (37) is fixed on the upper shaping fixing frame (36), and an upper shaping head (38) is fixed to the output shaft of the upper shaping cylinder (37); as Figure 4 , Figure 5 As shown, the lower shaping mechanism (5) includes a lower shaping fixing frame (39), on which a lower shaping head (40) is fixed. A lower shaping support rod (41) is connected to the bottom of the lower shaping head (40), and the lower shaping support rod (41) is connected to the output shaft of the lower shaping cylinder (42). The bottom of the lower shaping support rod (41) is provided with a lower shaping support rod wedge surface (43).

[0016] The upper shaping machine only acts as a downward pressing mechanism, deforming the glass to meet the requirements of glass contour. The lower shaping machine only acts as an upward pressing mechanism, deforming the glass to meet the requirements of glass contour. The lower shaping mechanism is fixed on the substrate. There are two similar structures, each with three shaping heads. Each shaping head is located below the glass shaping point. The shaping head is raised by the lower shaping cylinder (42) driving the wedge surface, which in turn drives the shaping head.
