【技术实现步骤摘要】
本技术涉及一种玻璃热弯加工的设备,特别涉及汽车挡风玻璃的热 弯加工的设备。繁扠不现有技术中,有一种用于汽车前挡风玻璃的生产的热弯炉,其主要包括 呈长方体形的框架,框架内水平设置有升降平台,框架两侧分别设有两链轮, 寧架中部位于链轮上方设有转轴,转轴上设有四个绞盘,转轴与主电机的输 出轴之间传动连接,主电机与框架相对固定,绞盘上分别绕装有链条,各链条一一对应绕过相应链轮与升降平台相连接;框架内位于升降平台上方还水 平固定设有若干电炉丝。该装置主要用于汽车前挡风玻璃的热弯成型,其工 作时,将用于热弯的模具放置在升降平台上,使模具的型面向上,在模具的 型面上方放置裁切好的工件,即平板玻璃或预成型的玻璃,然后主电机转动, 链条绕在绞盘上,使升降平台上升到接近电炉丝的位置,电炉丝通电发热使 玻璃软化,软化后的玻璃会平贴到模具的型面上,冷却后取出,热弯成型过 ,结束。其不足之处在于在平板玻璃产生形变过程中,玻璃的局部会逐渐 远离电炉丝,而另外一些局部与电炉丝间的间距变化不犬,导致玻璃上局部 温度不均匀,在成型过程中容易引起玻璃的球面过渡不圆滑,影响产品质量; 此外,由于 ...
