A production line for automotive tempered glass

Abstract

The invention discloses a production line of automobile toughened glass. The production line comprises a machine frame and a shaping device, wherein the shaping device comprises an upper die assembly and a lower die assembly, the upper die assembly is arranged on the machine frame, and the lower die assembly and the upper die assembly are in longitudinal alignment, are arranged on the machine frame or a base surface in a sliding manner, and can be moved out of the machine frame. In the production line disclosed by the invention, the lower die assembly and the upper die assembly are in longitudinal alignment and are arranged on the machine frame or the base surface in the sliding manner, and the base surface can be ground, so that when a mold needs to be replaced or when the mold needs to be overhauled and maintained, the mold can be placed on the lower die assembly firstly, then the lower die assembly is pulled out of the machine frame, the operating space can be effectively enlarged, the usage is greatly convenient, the labor intensity of workers is reduced, time desired for replacing or overhauling of the mold can be effectively shortened, and the production efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the field of automobile glass processing and production equipment, in particular to an automobile tempered glass production line. Background technique [0002] The automobile tempered glass production line is used to process and shape automobile glass, and usually includes a forming device and a tempering cooling device. The forming device usually includes an upper mold assembly and a lower mold assembly. The upper mold installed on the upper mold assembly And the lower mold installed on the lower mold assembly is used to hot-press the automotive glass workpiece to form a corresponding shape, which is usually used to manufacture double-curved glass with a certain curvature. In the use of the automobile tempered glass production line, different upper molds and lower molds need to be replaced for different shapes and sizes of automotive glass workpieces. The upper mold and the lower mold are usually detachably installed on the up...

Problems solved by technology

In the use of the automobile tempered glass production line, different upper molds and lower molds need to be replaced for different shapes and sizes of automotive glass workpieces. The upper mold and the lower mold are usually detachably installed on the upper mold assembly and the lower mold assembly. When it is necessary to replace the mold or perform maintenance, the upper mold is usually placed on the lower mold, and then the upper mold is removed from the upper mold assembly, and then the upper mold and the lower mold or together with the lower mold parts together from the frame, and because of the large area of ​​the automobile glass, the volume and weight of the upper mold assembly and the lower mold assembly are usually larger, especially the lower mold assembly, because the lower mold assembly needs Install the structure for conveying the automotive glass workpiece and the structure for adjusting the position of the lower mold, so its volume and weight are usually very large, and the operating space near the upper mold assembly and the lower mold assembly is usually small, so it is difficult to replace or overhaul It is very difficult and time-consuming to maintain the mold, the labor intensity of the workers is high, it is inconvenient to use, and it will also cause a reduction in production efficiency

[0003] On the other hand, the tempering cooling device of the automobile tempered glass production line usually cools the hot-pressed automobile glass workpiece through the air grille, because the air outlets of the air grille are spaced apart from each other, and the wind force of each air outlet on the air grille It is difficult to ensure complete consistency, so it is easy to make the cooling speed of each part of the automotive glass workpiece inconsistent, so that the molded automotive glass workpiece will be deformed again due to the uneven temperature of each part during the tempering cooling process, affecting product quality

At present, the tempering cooling device of some automobile tempered glass production lines connects the air grid to the frame through a swing mechanism, so that during the tempering cooling process, the air grid can swing back and forth, which can improve the wind resistance of various parts of the automotive glass workpiece. The uniformity is conducive to improving product quality. However, since the automotive glass workpiece is usually large, the volume and weight of the corresponding air grille and the inertia during the swinging process of the air grille are also very large. Therefore, the structural strength of the swing mechanism and the frame, The stability and the driving force requirements of the corresponding driving device are very high, which makes the structure of the equipment too complicated, the manufacturing cost of the equipment is high, and it is also prone to failure. Uniformity creates limitations and in turn no further improvement in product quality
