    摘要： An apparatus for the automated production of glass assemblies comprises: a turning machine with at least two spindles which are rotatable about a common axis of rotation and which each have a workpiece holder, wherein the workpiece holders are arranged opposite one another; one or more gas burners or lasers fixed on a first tool carriage which is movable in parallel and/or perpendicularly to the axis of rotation; one or more drives for driving a rotational movement of the spindles and a movement of the first tool carriage; a pressure module including a pump device at least one working cylinder for applying a pressure to an inner tube and/or to a space between the inner tube and an outer tube; and a control unit configured to control the burners or lasers, one or more drives, the first tool carriage and the pressure module.

    摘要： A molding tool, a method, and an apparatus for hot forming of glass are provided that provide glass products used for pharmaceutical packaging. The molding tool includes a forming mandrel for reshaping at least a portion of a heated region of a glass precursor. The mandrel has a temperature-stable core material and an alloying element. The core material is made of precious metals, in particular of platinum group elements, and the further alloying element is made of one of tungsten, zirconium, rhodium, molybdenum, and rhenium.

    摘要： The invention relates to a method and apparatus for shaping an elongated glass body 81, which is a glass tube or glass rod and has an initial profile, to an elongated glass body having a different profile. In order to be properly shaped, an elongated glass body 81 passes through, in a hot malleable state, a nip, which is formed by squeezing rollers 1 and which has a nip width which is less than an outer dimension of the initial profile.In order to accomplish an enhanced precision of the shaping process, according to the invention the position of at least one of the squeezing rollers is varied continuously so that a contact area between the respective squeezing roller and the hot glass body is varied cyclic reciprocating movement. Disturbing effects such as local overheating of the squeezing rollers or an accumulation of dirt or glass particles on the surface of the squeezing rollers can thus be effectively prevented.

    摘要翻译： 本发明涉及一种用于将具有初始轮廓的细长玻璃体81（其为玻璃管或玻璃棒）成形为具有不同轮廓的细长玻璃体的方法和装置。 为了适当地成形，细长的玻璃体81以热的可延展状态通过由挤压辊1形成并且具有小于初始轮廓的外部尺寸的辊隙宽度的辊隙。 为了实现成型加工的精度提高，根据本发明，至少一个挤压辊的位置连续变化，使得各挤压辊与热玻璃体之间的接触面积发生循环往复运动。 因此可以有效地防止诸如挤压辊的局部过热或者挤压辊表面上的污垢或玻璃颗粒堆积的干扰效应。
