摘要： A process and apparatus for manufacturing slot-shaped openings on hollow sections is disclosed in which the openings are produced by a piercing cutting operation by means of a blade-type cutting tool by the displacement of material in a cutout-free manner. During the slotting operation, the hollow sections are supported from the inside around the openings to be formed. In order to produce slot-shaped openings in a simple manner while maintaining the shape of the hollow section on arbitrarily constructed hollow sections in a reliable process free of positional tolerances, the hollow section is inserted in a recess of an internal high pressure forming tool. The hollow section is slotted by the interaction of the cutting action of a cutting tool integrated in the internal high pressure forming tool and an internal high pressure generated inside the hollow section.

摘要： The invention concerns a method and apparatus for production of a hollow section (1) in which a coiled pre-shape of the hollow section (1) is deep drawn from a sheet part, which is pre-bent after a trimming process and coiled into the final shape of hollow section (1). The edges (45) of hollow section (1) lying in the peripheral direction are then joined together in the contact region. In order to improve the joining capability of hollow section (1) to other components in simple fashion, it is proposed that before the coiling process at least one flat site (35) for joining to another component be embossed before the coiling process in a pre-bent region of the hollow section (1).
摘要翻译：本发明涉及一种用于生产中空部分（1）的方法和装置，其中中空部分（1）的螺旋形预成型件从片材部分深度拉伸，该片材部分在修剪过程之后被预弯曲并卷成中空部分（1）的最终形状。然后在接触区域中将位于圆周方向的中空部分（1）的边缘（45）接合在一起。为了以简单的方式将中空部分（1）的连接能力提高到其它部件，提出在卷取过程之前，在卷取过程之前，在预先卷绕过程之前，至少一个用于接合另一部件的平坦部位（35）被压印（1）的吸收区域。

摘要： An apparatus and method of attaching an exhaust manifold to an engine's cylinder head utilizing an oversized hole in the manifold, a stud fastener extending through the oversized hole, a spacer element around the stud fastener, and a nut adapted to be tightened to engage the spacer element and the flange wherein a flat gasket is compressed to a desired extent which is not so excessive that it inhibits sliding movement caused by thermal growth of the manifold.
摘要翻译：使用歧管中的超大孔将排气歧管连接到发动机气缸盖的装置和方法，延伸穿过超大孔的螺柱紧固件，围绕螺柱紧固件的间隔件，以及适于紧固以接合间隔件的螺母元件和凸缘，其中平垫圈被压缩到所需程度，其不会过大，从而阻止由歧管的热生长引起的滑动。
