A press bending glass plate heating device, comprising a bracket mounted on the bracket; for bending die bending glass plate, the bending modulus including the relative configuration of the level of the upper and lower pressure parts, the upper and lower pressing member has a surface forming complementary, forming under the Ministry of rail pressing with continuous edge is consistent with the shape of the glass plate around the edges; the driving device is arranged on the bracket, so as to selectively increase and decrease of the lower press member, thereby forming track positioning in receiving the first glass plate down position between the upper and lower pressing positioning in parts forming the first glass plate rise in position. The location for the first drop after bending glass sheet transfer and then receive second glass plate; conveyor installed on the bracket, the conveyor along a predetermined The path of a generally horizontal glass plate from the heating end of the bracket through the upper and lower press bending zone transfer between components to the cooling end of the bracket, the conveyor in bending area includes many moving parallel to the horizontal axis installation, these horizontal axis through the lower pressure parts forming track following path; and a plurality of transfer rollers, the transfer roller is rotatably fixed to the longitudinal one on the horizontal axis, the transfer roller is located above the edge of the periphery of the internal forming track, the transfer roller has the opposite ends, the end portion extending from the shaft radial and close to the opposite side of the edge forming track positioning, the transfer the roller with uniform diameter, from the end of the cross section decreases gradually, thus forming a bearing surface and after glass plate bending curvature complementary generally concave, The surface for receiving a glass plate after bending and bending curvature of the glass plate has remained unchanged in the glass plate along the transmission path to the conveying cooling end of the stent, when forming orbit at a lowered position, the forming of the transfer roller bearing track located on the surface below, which helps the glass plate along transmission path, and when the forming track in the up position, above the track position on the transfer roller forming, which is beneficial to the pressure between the upper and lower parts of forming glass plate.

本专利技术总体涉及玻璃板的压制弯曲设备,具体涉及设有可互换组合件的压制弯曲设备,该互换组合件由下部压制件及互锁的传送机构成。弧形的传送辊子装在连续的外周压制弯曲环内,使得传送辊子的外端部紧邻于压制弯曲环以支承加热变软的玻璃板。相关技术概述玻璃板传送和弯曲设备用于大量生产汽车工业中及其它方面所用的曲面或弯曲的玻璃板。在大量生产操作时,玻璃板一般一个接一个地沿辊子式传送机的水平路径传送通过生产加工线。生产加工线上的具体操作包括将玻璃加热到其软化温度、将玻璃弯曲到要求的形状和最后控制冷却已弯曲的玻璃板,以便玻璃板退火或回火。玻璃板在穿过加热炉时被加热到软化点,然后玻璃板由传送机送到成形或弯曲区域,在此区域玻璃板被准确地成形为要求的形状。成形后的玻璃板被输送到冷却台,在该台进行可控的冷却而被回火或退火。用于成形加热软化玻璃的主要工艺包括辊压成形、压制成形和重力成形。在滚压成形时,将加热的玻璃板置于一组成形辊子的顶部上进行传送,或放在上面一组成形辊子和下部一组成形辊子之间,该辊子啮合玻璃而进行成形。压制弯曲涉及将玻璃板定位在弯曲设备的互补的上、下成形件之间。然后用下部压制件啮合正确取向的玻璃板的下部边缘部分,并升高传送机辊子而在压制件的互补成形表面之间压制到准确的预定曲率。在重力成形中,可利用重力使加热的玻璃板弯曲到与框架或一组成形辊子的形状一致。为适合汽车使用,平玻璃板必需准确成形到由车窗口的形状和轮廓确定的曲率。另一个重要要求是,窗玻璃必须满足严格的光学要求,而且应没有光学缺陷和反射畸变,这些缺陷和畸变可能妨碍通过玻璃的观察区进行观察。在过去若 ...
