摘要： The impact-type anchor (1) consists of a metal sleeve (2) provided with a throughgoing passage (3) tapering towards a leading end of the sleeve, into which bore an expander body (5) can be driven to expand the impact-type anchor. The throughgoing passage (3) has a rear cylindrical portion provided with an internal thread (4) as well as a tapering portion. So that the metal sleeve can be inexpensively manufactured while providing pull-out values that are the same as those of a metal sleeve made of solid material, the metal sleeve is stamped out of a sheet metal blank and then rolled up to form a sleeve which is joined at its seam. Furthermore, in order to form the tapering internal bore the expandable legs (7) have a first section (7a) that is bent inwards and a second section (7b) that is bent onto the outer face of the first section. The two sections (7a, 7b) resting one against the other are connected non-displaceably to one another, for example, by means of a punched point (9).
摘要翻译：所述冲击式锚固件（1）由金属套筒（2）组成，所述金属套筒（2）设置有朝着所述套筒的前端逐渐变细的通孔（3），所述孔可以被驱动以使膨胀机体（5）键入锚。通过通道（3）具有设置有内螺纹（4）的后圆柱形部分和锥形部分。因此，金属套筒可以廉价地制造，同时提供与由固体材料制成的金属套筒相同的拉出值，金属套筒从金属板坯料冲压出来，形成套筒，在其接缝处加入。此外，为了形成锥形内孔，可膨胀腿（7）具有向内弯曲的第一部分（7a）和弯曲到第一部分的外表面上的第二部分（7b）。彼此靠在一起的两个部分（7a，7b）例如通过冲压点（9）彼此不可移位地相互连接。

摘要： The expansible anchor consists of a shank having a threaded portion for fixing an article at its rear end and a reduced cross-sectioned portion with an adjoining expander cone at its front end, and, positioned over the reduced cross-sectioned portion, an expansible sleeve having longitudinal slits forming expansible segments and locking elements protruding beyond the diameter of the expansible sleeve and arranged on the expansible segments. To increase the holding force of the anchor and to allow the expander cone to slide-up and the expansible sleeve to expand in operation if the drilled hole become enlarged as a result of cracks forming, the locking elements consist of several interconnected punched elements on each expansible segment extending in a longitudinal direction of the expansible segments. Each punched element is triangular with a point directed towards the front end of the expansible segments. An improved method of making the expansible anchor which includes stamping a blank for the expansible sleeve somewhat undersized from sheet metal, subsequently pressing it and then punching the punched elements in the expansible sleeve is also described.
摘要翻译：可膨胀锚固件包括具有用于在其后端固定物品的螺纹部分的杆和在其前端具有邻接的膨胀锥的减小的横截面部分，并且位于减小的横截面部分上方的可膨胀套筒具有形成可膨胀段和锁定元件的纵向狭缝突出超过可膨胀套筒的直径并且布置在可膨胀段上。为了增加锚固件的保持力并允许膨胀锥体向上滑动，并且如果钻孔由于裂纹形成而增大，则可膨胀套筒在操作中膨胀，锁定元件由每个上的几个相互连接的穿孔元件组成可膨胀段在可膨胀段的纵向方向上延伸。每个穿孔元件是三角形的，其中一个点指向可扩展段的前端。还描述了制造可膨胀锚的改进方法，该方法包括冲压坯料以使可膨胀套管略微小于金属板，稍后将其压制，然后冲压可膨胀套管中的冲压元件。
