    • When heating and bending glass sheets in a furnace, it is desirable to raise the sheets towards the furnace heat sources to increase obtainable temperature differentials and reduce heating power. Disclosed is a method of bending a glass sheet on an apparatus comprising an elongate furnace divided along its length into a plurality of heating zones, each heating zone having an upper part, the method comprising the steps of supporting the glass sheet on a bending mould; moving the glass sheet through the zones of the furnace in a plurality of intermittent steps, each step substantially corresponding in length to the distance separating corresponding points of successive heating zones; exposing the glass sheet during its passage through said heating zones to a succession of furnace heat sources contained in the upper part of each zone of said furnace; heating the glass sheet to a heat-softened condition as a result of said exposure; allowing the heat-softened glass sheet to sag into conformity with said bending mould; and raising the bending i-nould, while still supporting the glass sheet, towards the furnace heat sources in at least one of the heating zones. The bent glass sheet may be used in the manufacture of a vehicle glazing.
    • 当在炉中加热和弯​​曲玻璃板时,期望将片材朝向炉子热源升高以增加可获得的温度差并降低加热功率。 公开了一种将玻璃板弯曲在包括沿其长度分割成多个加热区的细长炉的设备上的方法,每个加热区具有上部,该方法包括以下步骤:将玻璃板支撑在弯曲模具上; 在多个间歇步骤中将玻璃板移动通过炉的区域,每个步骤的长度基本上对应于分开连续加热区域的对应点的距离; 将玻璃板在其通过所述加热区域期间暴露于包含在所述炉的每个区域的上部中的一系列炉热源; 由于所述曝光,将玻璃板加热至加热软化状态; 允许热软化的玻璃板下垂与所述弯曲模具一致; 并且在仍然支撑玻璃板的同时,在至少一个加热区中朝向炉子热源提升弯曲部件。 弯曲的玻璃板可以用于制造车辆玻璃。

    • A press die set includes a hollow cylindrical guide bush mounted on a punch holder, a cylindrical retainer received within the guide bush, and a columnar guide post vertically mounted on a die holder and received within the retainer. First right angle grooves are formed on the outer surface of the guide post parallel to a longitudinal axis of the guide post. First planar surfaces are formed on an outer surface of the guide post parallel to the longitudinal axis of the guide post and perpendicular to a radius of the guide post. Second right angle grooves are formed on the inner surface of the guide bush parallel to a longitudinal axis of the guide bush. Second planar surfaces are formed on the inner surface of the guide bush parallel to the longitudinal axis of the guide bush and perpendicular to a radius of the guide bush. Cross roller bearings are positioned between the first and second right angle grooves, and plain roller bearings are positioned between the first and second planar surfaces.
