Description

Technical Field

[0001] This utility model relates to the field of automotive glass manufacturing technology, and in particular to a press structure for improving the optical quality of automotive windshields using an in-furnace forming method. Background Technology

[0002] A press is a specialized piece of equipment used to process glass blanks into the shapes required for automotive windshields. By using a corresponding mold and a pressurizing device, the automotive windshield is extruded and formed, thus completing the processing of the automotive windshield.

[0003] In the current automotive windshield processing, high-temperature glass is usually taken out of the furnace first and then formed using a press. During the removal process, the glass comes into contact with the external environment, which causes it to cool down. This requires an additional temperature compensation device to compensate for the cooling effect, which reduces the efficiency of the process. The secondary heating also affects the optical quality of the glass surface. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing technologies by proposing a press structure for improving the optical quality of automotive windshields using an in-furnace forming method. The technical solution adopted by this utility model is as follows:

[0005] A press structure for improving the optical quality of automotive windshields using an in-furnace forming method includes a housing assembly. The housing assembly includes a frame, a lower insulation box, and an upper insulation box. The lower insulation box is installed below the front end of the frame, and the upper insulation box is installed above the front end of the frame. An upper pressing component is installed through the upper wall of the upper insulation box, and an upper lifting component is installed through the lower wall of the lower insulation box. A roller conveyor is installed inside the lower insulation box, and a glass body is placed on the roller conveyor.

[0006] As an improvement, the upper pressing assembly includes a pressing protrusion, a pressing plate, and a first guide rod, wherein the pressing protrusion is provided with a pressing plate at its upper end, and the pressing plate is provided with a first guide rod at its upper end.

[0007] As an improvement, the upper lifting assembly includes an upper lifting plate and a second guide rod, and the lower end of the upper lifting plate is connected to the second guide rod.

[0008] As an improvement, a control component is installed at the rear end of the frame, an upper connecting component is installed at the upper end of the control component, a lower connecting component is installed at the lower end of the control component, and a pressure valve assembly is installed inside the control component.

[0009] As an improvement, the control component includes a hydraulic tank, a water pump, a central cavity, and a telescopic cavity. The water pump is installed at the rear end of the hydraulic tank, and a central cavity is provided in the middle of the hydraulic tank. Telescopic cavities are installed on the upper and lower sides of the central cavity.

[0010] As an improvement, the upper connecting assembly includes a first piston plate, a first lifting rod, and a first connecting plate, wherein the upper end of the first piston plate is connected to the first lifting rod, and the upper end of the first lifting rod is connected to the first connecting plate.

[0011] As an improvement, the lower connecting assembly includes a second piston plate, a second lifting rod, and a second connecting plate, wherein the lower end of the second piston plate is connected to the second lifting rod, and the lower end of the second lifting rod is connected to the second connecting plate.

[0012] As an improvement, the pressure valve assembly includes a valve body, a middle block, a valve core, a spring, and a support frame. The middle block is installed inside the valve body, the valve core is installed inside the middle block, and springs are connected to the upper and lower ends of the valve core. The end of the spring away from the valve core is connected to the support frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention relates to a press structure for improving the optical quality of automotive windshields using an in-furnace forming method. This structure allows the glass body to be formed inside the furnace, significantly reducing the firing temperature of the glass body and thus improving the surface optical quality. Due to the structural change, the glass body is formed in a high-temperature environment, eliminating the need to increase the compensation furnace exit temperature to achieve the glass body forming, thereby improving the time and quality stability of the yield, and also increasing the efficiency of glass body production.

[0015] This application achieves this by making the working pressures of the two pressure valve assemblies different, thereby controlling the upper lifting assembly and the upper pressing assembly to work in stages through a single water pump. This makes the working steps of the equipment more accurate and prevents errors in the working steps that could lead to damage to the raw materials. Attached Figure Description

Detailed Implementation

[0020] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] like Figure 1 and Figure 2 As shown, the device includes an outer shell assembly 1, which includes a frame 101, a lower insulation box 102, and an upper insulation box 103. The lower insulation box 102 is installed below the front end of the frame 101, and the upper insulation box 103 is installed above the front end of the frame 101. An upper pressing component 2 is installed through the upper wall of the upper insulation box 103, and an upper lifting component 3 is installed through the lower wall of the lower insulation box 102. A roller conveyor 4 is installed inside the lower insulation box 102, and a glass body 5 is placed on the roller conveyor 4.

[0022] This structure allows the glass body 5 to be formed inside the furnace, which greatly reduces the firing temperature of the glass body 5 and thus improves the surface optical quality. Because the structure changes the glass body 5 to be formed in a high-temperature environment, it is not necessary to increase the compensation furnace temperature to achieve the forming of the glass body 5, thereby improving the time and quality stability of the yield and also improving the production efficiency of the glass body 5.

[0023] like Figure 1 As shown, the upper pressing component 2 includes a pressing protrusion 201, a pressing plate 202 and a first guide rod 203, and the pressing protrusion 201 is provided with the pressing plate 202 at its upper end, and the pressing plate 202 is provided with the first guide rod 203 at its upper end.

[0024] like Figure 1As shown, the upper lifting assembly 3 includes an upper lifting plate 301 and a second guide rod 302, and the lower end of the upper lifting plate 301 is connected to the second guide rod 302.

[0025] like Figure 2 and Figure 3 As shown, a control component 6 is installed at the rear end of the frame 101, an upper connecting component 7 is installed at the upper end of the control component 6, a lower connecting component 8 is installed at the lower end of the control component 6, and a pressure valve component 9 is installed inside the control component 6.

[0026] like Figure 2 As shown, the control component 6 includes a hydraulic tank 601, a water pump 602, a central cavity 603, and a telescopic cavity 604. The water pump 602 is installed at the rear end of the hydraulic tank 601, the central cavity 603 is provided in the middle of the interior of the hydraulic tank 601, and the telescopic cavity 604 is installed on the upper and lower sides of the central cavity 603.

[0027] like Figure 2 As shown, the upper connecting assembly 7 includes a first piston plate 701, a first lifting rod 702 and a first connecting plate 703, and the upper end of the first piston plate 701 is connected to the first lifting rod 702, and the upper end of the first lifting rod 702 is connected to the first connecting plate 703.

[0028] like Figure 2 As shown, the lower connecting assembly 8 includes a second piston plate 801, a second lifting rod 802, and a second connecting plate 803. The lower end of the second piston plate 801 is connected to the second lifting rod 802, and the lower end of the second lifting rod 802 is connected to the second connecting plate 803.

[0029] like Figure 3 As shown, the pressure valve assembly 9 includes a valve body 901, a middle block 902, a valve core 903, a spring 904, and a support frame 905. The middle block 902 is installed inside the valve body 901, the valve core 903 is installed inside the middle block 902, and the upper and lower ends of the valve core 903 are connected to the spring 904. The end of the spring 904 away from the valve core 903 is connected to the support frame 905.

[0030] By applying different working pressures to the two pressure valve assemblies 9, the upper lifting assembly 3 and the upper pressing assembly 2 can be controlled in stages by a single water pump 602. This ensures more accurate operation of the equipment and prevents errors in the working steps that could damage the raw materials.

[0031] During use, the equipment is first installed inside the glass heating furnace, near the outlet. After processing in the furnace, the glass can be directly conveyed to the lower insulation box 102 and the upper insulation box 103, and then transported by roller conveyor 4 to the space between the upper support plate 301 and the pressing protrusion 201. Throughout this process, the glass body 5 remains inside the heating furnace, so its temperature is not lost, eliminating the need for secondary heating. Then, all components behind the frame 101 are outside the heating furnace. Next, the water pump 602 is turned on, drawing liquid from the middle cavity 603 of the hydraulic tank 601. A partition plate separates the connection between the middle cavity 603 and the telescopic cavity 604. A pressure valve assembly 9 is installed on each partition plate, and the spring 904 of the lower partition plate has a lower elastic coefficient than the spring 904 on the upper partition plate. This ensures that when the water pump 602 operates, the liquid in the middle cavity 603 is drawn out first. The liquid is extracted, and then the liquid pressure in the middle cavity 603 first opens the valve core 903 of the lower pressure valve assembly 9, thereby opening the valve core 903 and the middle block 902, allowing the liquid in the lower telescopic cavity 604 to enter the middle cavity 603. This causes the second piston plate 801 to drive the second lifting rod 802 to rise, causing the second connecting plate 803 to drive the second guide rod 302 to rise, thereby causing the upper lifting plate 301 to rise, lifting the glass body 5 from the roller conveyor 4, and then lowering the telescopic cavity 604. After the liquid inside 4 is extracted, the liquid in the upper telescopic cavity 604 will also be extracted. Similarly, the first piston plate 701 will descend, causing the first lifting rod 702 and the first connecting plate 703 to drive the first guide rod 203 to descend. This will cause the pressing plate 202 to drive the pressing protrusion 201, so that the pressing protrusion 201 cooperates with the upper support plate 301 to process the glass body 5, thereby forming the glass body 5. The formed glass body 5 will be placed back on the roller conveyor 4, conveyed out, and cooled.

[0032] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
