摘要:
A framework made of frame pieces for a switchgear cabinet, wherein the frame pieces are preferably laterally reversed in relation to their cross-sectional diagonal and have profiled sides perpendicular to the outer sides of the framework and have fastening recesses. In an area of an inner side, the profiled sides end in sections that form a recess for fastening mounting rails. By combining several known and novel features, a framework having easily manufactured frame pieces is created which optimally meets all requirements for use with a switchgear cabinet.

An inclination adapter for a support arm system, the adapter having a base part with an adjusting spindle and an inclination member, the base part and the inclination member pivotably connected to each other and the pivot movement performed via a coupling member which can be adjusted by the adjusting spindle. An inclination adapter which is sufficiently stable for a support arm system and has simple parts is produced because the base part and the inclination member comprise connection plates with central openings. Coupled spaced-apart, mutually facing bearing bars are integrally formed on the base part and the inclination member, respectively, and mounted to be pivotable parallel to the connection plates via the base part and the inclination member. The adjusting spindle is guided by a cam, which has a circular cross-section and is part of the coupling member, in a guide slot in a bearing bar of the inclination member, and the guide slot is in the region of the bearing bar which extends beyond the pivot mounting.
摘要:
A bracket for a suspension system for control units, control panels and the like, including a support body portion, having a substantially U-shaped base profile portion that is subdivided, by means of a separation rib extending parallel to its rib, into a closed supporting part and an open, U-shaped receiving part remote from the rib, in which continuous, longitudinally oriented screw receptacles are formed on the support part and the receiving part. To improve the torsional rigidity of the bracket and the entire suspension arrangement, the support part is stiffened in the longitudinal direction of the support body portion by means of two continuous diagonal ribs, which are joined together in the middle, and the screw receptacles of the support part are constructed in the corner regions that the diagonal ribs form with the base profile section.

A magazine is described which requires only a small surface area for its accommodation and which nevertheless holds a large number of tools. The magazine includes carrier units which are arranged in tower-like manner above one another and which are provided with a central cut-out and inwardly disposed tool mounts. This tower-like magazine is transportable and associated with a spatially fixed transport means which can be introduced into the central cut-out and which can transport the respective tools to a tool transfer position by short stroke and pivotal movements. Other magazine constructions are also described in the form of racks and towers.

A lifting and turning unit for a melting or casting plant. The lifting and turning unit for a deposit stand, preferably a table, for ingot molds of a vacuum melting and casting plant is provided. The unit consists of a tubular, vertically arranged lifter column that is axially movable with a hydraulic piston-cylinder unit and that has its upper end carrying the ingot mold table. A guide system composed of guide columns and of a yoke is provided. The guide columns serve for guiding the lifter column and for protecting the lifter column against twisting. The drive for the rotation of the rotatable ingot mold table is connected to the lifter column away from the harsh chamber environment. The unit provides an extremely low maintenance lifting and turing device wherein the longitudinal movements and the rotary movements can be executed separately from one another and thus allow for an exact positioning of the table.
摘要:
A tilting mechanism for precisely controlling the pouring of metal from a melting crucible is disclosed. The mechanism utilizes a pressure roller journalled in an adjustable bearing mount to clearance-free urge a rack against a pinion to tilt the crucible. At least one boom is disposed on the adjustable bearing mount to pivot the hydraulic cylinder in a parallel direction relative to the tilting shaft.
