Description

Technical Field

[0001] This utility model relates to the technical field of glass, and in particular to a one-time forming device for curved automotive glass based on float glass process. Background Technology

[0002] Glass is a transparent, rigid material widely used in construction, automobiles, electronics, and many other fields. In automobile manufacturing, curved automotive glass is an important component, requiring not only good light transmission but also a specific curved shape to meet design requirements. Therefore, specialized forming equipment is needed in the production of curved glass to process the glass into the required curved shape.

[0003] Traditional curved glass forming equipment typically uses a rigid pressure head to directly press down on the preheated and softened glass during the shaping process. This method cannot be flexibly adjusted according to the curvature of different car models. Furthermore, uneven stress on different parts of the glass during the hot-melt forming process can easily lead to deviations in the curvature fit, resulting in a mismatch between the curvature of the finished glass and the design requirements of the car body. This can even cause the glass to crack or deform, affecting the assembly sealing and appearance consistency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, this utility model provides a one-time forming device for curved automotive glass based on float glass process. Through the setting of the shaping mechanism, it can perform preliminary curved shaping on the preheated and softened glass. Then, through a flexible and buffered downward pressing method, the glass is subjected to uniform force during the shaping process, avoiding cracking or deformation due to stress concentration.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a one-time forming device for curved automotive glass based on float glass process, including a forming device and a shaping mechanism. The shaping mechanism is disposed on the outer wall of the forming device and includes a mounting groove, a base, a first power source, a curved base, a buffer assembly, an adjustment assembly, and a conveying assembly. The forming device has a mounting groove inside, the base is installed inside the mounting groove, the first power source is installed inside the base, the curved base is installed on the outer wall of the base, and the curved base is connected to the output end of the first power source. The buffer assembly is disposed inside the curved base, the adjustment assembly is disposed inside the mounting groove, and the conveying assembly is disposed on the inner wall of the mounting groove.

[0007] In addition, the curved automotive glass one-time forming device based on float glass process proposed above according to this utility model may also have the following additional technical features: Specifically, each set of buffer components includes a sleeve, a spring, and a pressure head. A fixing groove is provided on the curved base, the sleeve is fixed inside the fixing groove, the spring is installed inside the sleeve, and the pressure head is connected to the other end of the spring.

[0008] Specifically, each set of adjustment components includes a second power source, a fixed base, and a conveyor belt. The second power source is installed inside the mounting slot, the fixed base is connected to the output end of the second power source, and the conveyor belt is installed on the outer wall of the fixed base.

[0009] Specifically, the conveying assembly includes a bracket, a guide rail, a connecting column, and a fixed bracket. The bracket is installed on the inner wall of the mounting groove, the guide rail is installed on the outer wall of the bracket, the connecting column is connected to the moving block of the guide rail, and the fixed bracket is connected to the other end of the connecting column.

[0010] Specifically, the molding device is equipped with a cooling mechanism, which includes a fan, an air supply pipe, a connecting block, and multiple sets of nozzles. The fan is located inside the mounting groove, the air supply pipe is connected to the output end of the fan, the connecting block is connected to the other end of the air supply pipe, and the nozzles are installed on the outer wall of the connecting block.

[0011] Specifically, a control panel is installed on the outer wall of the molding device, and a protective cover is installed on the outer wall of the molding device.

[0012] Specifically, guide columns are installed on the outer wall of the fixed base, and guide grooves are provided on the forming device.

[0013] Specifically, the fan has three heat dissipation holes, which are located on both sides of the fan.

[0014] Compared with existing technologies, this invention has the following advantages: By creating an unsupported state at the bottom of the glass, the preheated and softened glass collapses on its own, thus initially shaping the desired curved surface. Subsequently, a buffer assembly is installed on the curved base, and a flexible, buffered pressing method is achieved through the elastic deformation of the spring and the flexible contact of the silicone pressure head. This pressing method ensures that the glass is subjected to uniform force in all parts during the shaping process, effectively avoiding glass breakage or deformation caused by stress concentration.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The following describes an embodiment of the present invention with reference to the accompanying drawings: a one-time forming device for curved automotive glass based on float glass process.

[0020] like Figures 1-5 As shown in the figure, an embodiment of the present invention provides a one-time forming device for curved automotive glass based on float glass process, comprising a forming device 1 and a shaping mechanism 2.

[0021] The shaping mechanism 2 is installed on the outer wall of the forming device 1. The shaping mechanism 2 includes a mounting groove 21, a base 22, a first power source 23, a curved base 24, a buffer assembly 25, an adjustment assembly 26, and a conveying assembly 27.

[0022] The molding device 1 has an internal mounting groove 21, a base 22 is installed inside the mounting groove 21, a first power source 23 is installed inside the base 22, a curved base 24 is installed on the outer wall of the base 22 and is connected to the output end of the first power source 23, a buffer assembly 25 is installed inside the curved base 24, an adjustment assembly 26 is installed inside the mounting groove 21, and a conveying assembly 27 is installed on the inner wall of the mounting groove 21.

[0023] Each set of buffer components 25 includes a sleeve 252, a spring 253, and a pressure head 254.

[0024] A fixing groove 251 is provided on the curved base 24, a sleeve 252 is fixed inside the fixing groove 251, a spring 253 is installed inside the sleeve 252, and a pressure head 254 is connected to the other end of the spring 253.

[0025] Each set of adjustment components 26 includes a second power source 261, a fixed base 262, and a conveyor belt 263.

[0026] The second power source 261 is installed inside the mounting slot 21, the fixed base 262 is connected to the output end of the second power source 261, and the conveyor belt 263 is installed on the outer wall of the fixed base 262.

[0027] The outer wall of the fixed base 262 is equipped with a guide post 264, and the forming device 1 is provided with a guide groove 265.

[0028] The conveying assembly 27 includes a bracket 271, a guide rail 272, a connecting column 273, and a fixed bracket 274.

[0029] The bracket 271 is installed on the inner wall of the mounting groove 21, the guide rail 272 is installed on the outer wall of the bracket 271, the connecting column 273 is connected to the moving block of the guide rail 272, and the fixed bracket 274 is connected to the other end of the connecting column 273. It should be noted that the first power source 23 and the second power source 261 described in this embodiment are cylinders.

[0030] Specifically, when glass forming is required, the conveyor belt 263 first transports the preheated and softened glass to above the fixed support 274. Then, the second power source 261 activates, driving the fixed base 262 downwards, simultaneously moving the conveyor belt 263 downwards as well. At this time, the guide posts 264 on the outer wall of the fixed base 262 slide within the guide groove 265, providing guidance and support for the movement of the fixed base 262, ensuring a smooth movement process.

[0031] Meanwhile, as the conveyor belt 263 moves downward, the glass gradually comes into contact with the fixed support 274. The fixed support 274 serves to support the glass, and as the softened glass loses the support of the conveyor belt 263, the center of the glass collapses downward, thus forming a preliminary curved shape.

[0032] Subsequently, the guide rail 272 in the conveying assembly 27 is activated, driving the connecting column 273 and the fixed bracket 274 to move horizontally, conveying the glass, which has initially formed a curved shape, to the top of the curved base 24. At this time, the first power source 23 is activated, driving the curved base 24 to move upward, so that the curved base 24 contacts the glass, while the glass separates from the fixed bracket 274.

[0033] During contact, the buffer assembly 25 plays its role. When the glass exerts pressure on the curved base 24, the pressure head 254 compresses the spring 253. The spring 253 contracts within the sleeve 252, which acts as a buffer to prevent the glass from being damaged due to excessive force. It also prevents pressure concentration from causing indentations or cracks.

[0034] In one embodiment of this application, such as Figure 5 As shown, the molding device 1 is equipped with a cooling mechanism 3.

[0035] The cooling mechanism 3 includes a fan 31, an air supply pipe 33, a connecting block 34, and multiple sets of nozzles 35.

[0036] The blower 31 is installed inside the mounting slot 21, the air supply pipe 33 is connected to the output end of the blower 31, the connecting block 34 is connected to the other end of the air supply pipe 33, and the nozzle 35 is installed on the outer wall of the connecting block 34.

[0037] Specifically, after the glass contacts the curved base 24 and completes its initial forming, the first power source 23 starts, driving the curved base 24 downwards so that the glass re-contacts the fixed bracket 274. Then, the guide rail 272 on the conveying assembly 27 continues to move, smoothly transferring the formed glass to the corresponding area of ​​the cooling mechanism 3. At this time, the fan 31 starts, delivering the generated cooling airflow through the air pipe 33 to the connecting block 34, and then evenly spraying it onto the surface of the formed glass from multiple sets of nozzles 35 on the outer wall of the connecting block 34. The cooling airflow can quickly remove the heat from the glass surface, allowing the glass to cool down and solidify rapidly, effectively preventing the glass from deforming or being damaged due to excessive temperature during subsequent processing, and ensuring the forming quality of the glass.

[0038] In one embodiment of this application, such as Figure 1 As shown, a control panel 4 is installed on the outer wall of the molding device 1, and a protective cover 5 is installed on the outer wall of the molding device 1.

[0039] Understandably, the control panel 4 is equipped with multiple operation buttons and a display screen, allowing operators to control various components of the molding device 1. The protective cover 5 is installed on the outer wall of the molding device 1, and its main function is to protect the internal components of the molding device 1, preventing external dust, debris, etc., from entering the device and affecting its normal operation.

[0040] In one embodiment of this application, such as Figure 1 As shown, the fan 31 has heat dissipation holes 32.

[0041] Understandably, the heat dissipation holes 32 are evenly distributed on the outer casing of the fan 31. This ensures that the heat generated by the fan 31 during long-term operation can be dissipated in a timely manner to avoid damage due to overheating, and also prevents dust and other impurities from entering the fan 31 through the heat dissipation holes 32 and affecting its normal operation.

[0042] Working principle: When glass forming is required, the conveyor belt 263 first transports the preheated and softened glass to above the fixed support 274. Then, the second power source 261 activates, driving the fixed base 262 downwards, simultaneously moving the conveyor belt 263 downwards as well. At this time, the guide post 264 on the outer wall of the fixed base 262 slides within the guide groove 265, providing guidance and support for the movement of the fixed base 262, ensuring smooth movement. Simultaneously, as the conveyor belt 263 moves downwards, the glass gradually comes into contact with the fixed support 274. The fixed support 274 serves to support the glass, and as the softened glass loses the support of the conveyor belt 263, the center of the glass collapses downwards, forming a preliminary curved shape. Subsequently, the guide rail 272 in the conveyor assembly 27 activates, driving the connecting post 273 and the fixed support 274 to move horizontally, transporting the pre-formed curved glass to above the curved base 24. At this time, the first power source 23 starts, driving the curved base 24 to move upward, so that the curved base 24 contacts the glass, and the glass separates from the fixed bracket 274. During the contact process, the buffer component 25 plays its role. When the glass exerts pressure on the curved base 24, the pressure head 254 compresses the spring 253. The spring 253 contracts in the sleeve 252, which plays a buffering role, preventing the glass from being damaged due to excessive force, and also preventing pressure concentration, which could cause indentations or cracks. After the glass contacts the curved base 24 and completes the initial forming, the first power source 23 starts, driving the curved base 24 to move downward, so that the glass re-contacts the fixed bracket 274. Then, the guide rail 272 on the conveying component 27 continues to move, smoothly moving the formed glass to the corresponding area of ​​the cooling mechanism 3. At this time, the fan 31 starts, dissipating heat through the heat dissipation holes 32, and at the same time, the generated cooling airflow is transported to the connecting block 34 through the air supply pipe 33, and then evenly sprayed onto the surface of the formed glass by multiple sets of nozzles 35 on the outer wall of the connecting block 34. The cooling airflow can quickly remove heat from the glass surface, allowing the glass to cool and set rapidly. This effectively prevents deformation or damage due to excessive temperature during subsequent processing, ensuring the quality of the formed glass.
