Advantageously, the device comprises at least two cavities formed on the side surface of the sleeve, which are spaced apart along a same circumference, and at least one wedge-like element that is fastened to the mould and can be alternatively engaged in one of said cavities of the sleeve, with a conical coupling, in order to lock the sleeve after a rotation of the same.

Apparatus for straight line shearing

A straight line shearing mechanism which includes a unique pneumatic control system to cause the operation of the shears. One feature involves the cushioning of the piston member of the pneumatic cylinder assembly on the return stroke. Another feature is the provision of an automatic retract to open the shears in the event that the shear blades do not complete their cutting stroke. Also, one blade of a set of shear blades may tilt in the event of excess tension between the blades. Additionally, one shear blade is pivotally adjustable about a pin member having an axis extending in the direction of travel of the blades. Further, the drop guides are horizontally adjustable relative to its associated shear blade in the direction of travel of the shear blade and also adjustable about a vertical axis.

Method and device for scrap knife gap adjustment in heavy plate shears

Bei bekannten Besäumscheren mit auslaufseitigem Schrottmesserpaar muss das bewegte obere Schrottmesser möglichst dicht an der besäumten Blechkante vorbeigeführt werden, was eine genaue Einstellung des oberen Schrottmessers erfordert. Bei einer Erhöhung der Blechdicke muss auch die Messerspaltweite für die Schrottmesser und für die Besäummesser vergrößert werden. Beim Besäumschnitt wird dann die Schnittkante schräger ausgebildet als bei kleiner Messerspaltweite. Dies macht aber eine Vergrößerung des Abstandes des Schrottobermessers zum Grobblech bzw. dessen Besäumkante erforderlich, da sonst das Schrottobermesser die Schnittkante des Grobblechs beschädigt. Umgekehrt darf bei kleinen Blechdicken und geringer Messerspaltweite der Abstand nicht zu groß sein, da sonst der Schrottstreifen nicht n bei der Besäumung wechselnder Blechdicken zu vermeiden, wird gemäß der Erfindung vorgeschlagen, dass in Abhängigkeit von der Blechdicke der Grobbleche (10) durch eine gleichzeitige Verschiebung der Schrottmesserschlittenführung (20, 20') in zwei rechtwinklig zueinander verlaufenden unterschiedlichen Richtungen (22, 23) eine gleichzeitige Verstellung der Schrottmesserspaltweite (6) und des Abstandes (5) zwischen dem Schrottobermesser (2) und der Besäummesserkante (4) durchgeführt wird. In known trimming scissors with a pair of scrap knives on the outlet side, the moving upper scrap knife must be moved as close as possible to the trimmed sheet metal edge, which requires precise adjustment of the upper scrap knife. If the sheet thickness is increased, the knife gap for the scrap knife and for the trimming knife must also be increased. In the trimming cut, the cutting edge is then formed more obliquely than with a small knife gap width. However, this makes it necessary to increase the distance between the scrap metal knife and the heavy plate or its trimmed edge, since otherwise the scrap metal knife will damage the cut edge of the heavy plate. Conversely, in the case of small ...

Cutting apparatus

A cutting apparatus is capable of cutting a work-piece depending upon the quality of the work-piece. The cutting apparatus produces parallelism between a knife edge of a cutting blade and a mounting face of the work-piece. A support having the blade is provided to a column capable of controlling a tilting angle of the blade in a blade length direction. Cutting is executed by controlling vertical movement of the blade. A driving source is capable of controlling movement linearly. The driving source produces a parallel relationship between a surface of a table and a knife edge. Different supports are each unitized to include a driving source and the blade vertically moved by the driving source. The different supports can be mounted interchangeably and selectively on a column of a cutting apparatus.
