Abstract:
Stamping machine with a series of tools having each a matrix and, at a certain interval, a stamp which is displaceable in a guiding sleeve. The guiding sleeves are plugged in interchangeably in a guiding plate. To each tool there is adjoined an engageable and disengageable coupling device used to transfer the desired stamping force to the corresponding stamp. Set of tools from said tools, to be provided in a stamping machine, a plurality of tools and a plurality of coupling devices being joined together to form a single structural unit.
Abstract:
Die Erfindung betrifft eine Messvorrichtung mit einem Messkopf (15) zur Positionsbestimmung eines Primärteils (27) auf einem Sekundärteil, wobei der Messkopf (15) fest mit einem Primärteil (27) verbunden bzw. in dieses integriert ist, das Primärteil (27) und das Sekundärteil einen Linearmotor (30) bilden, das Sekundärteil als Zahnstange (16) ausgebildet ist, die Zahnstange (16) zumindest ferromagnetisches Material aufweist und in einer Vorzugsrichtung (13) vorzugsweise äquidistante Zähne (18) aufweist, die zumindest ferromagnetisches Material aufweisen, der Messkopf (15) in Vorzugsrichtung (13) und entgegengesetzt dazu bewegbar ist, sich zwischen dem Messkopf (15) und der Zahnstange (16) ein Luftspalt befindet, und der Messkopf (15) zumindest einen Sensor (1-12,19,31) aufweist, mittels dem Magnetfelder zwecks Positionsbestimmung messbar sind.
Abstract:
The invention concerns a steel fibre for reinforcing castable, hardening materials, in particular concrete, the fibre extending substantially along a longitudinal axis and having longitudinal edges which deviate from the rectilinear shape. The invention is characterized in that the steel fibre is formed by a narrow sheet metal strip of uniform thickness (sheet thickness D), the longitudinal edges of this strip, viewed as cutting edges in the sheet plane, each having congruent wave-like shapes shifted parallel to one another and substantially composed of a series of polygons, the width of the parallel shift (b) being such that a continuous rectangular material strip (width d) is produced in the sheet plane between the wave-like longitudinal edges over the entire fibre length (I). The invention further concerns a method of producing this steel fibre.
