Pressure cylinder for a drafting arrangement of a textile machine

Abstract

The pressure cylinder has a piston (2), capable of being pressured by pressuring medium and set axially movably, in a cylinder case (1), a piston rod (3) extending through one end of the cylinder cap defining the cylinder and a switching disk (12) set movably axially with the piston (2) by frictional adhesion and co-operating with a switch (13) defining the position of the piston (2). The switching disc (12) is set in a pressure chamber (8) side and between the piston (2) and a cylinder base (6) so as to reach the initial position near the piston by pressure shot overcoming the frictional attachment on first pressurization of the pressure chamber (8).

Description

technical field

[0001] The invention relates to a pressure cylinder with a piston capable of applying pressure which is arranged axially movable in a cylinder housing, from which a piston rod protrudes, the piston rod passing through at least one cylinder head which closes the end face of the cylinder housing , wherein a switch disk is mounted displaceably on the piston rod and coaxially with the piston in a frictionally adhered manner, and this switch disk cooperates with a switch for determining the position of the internal piston. Background technique

[0002] Such pressure cylinders are preferably used in textile machine technology. Compression cylinders are used as loading devices in stretching mechanisms for fiber materials. A stretching mechanism is basically composed of an upper and lower roller structure, and a plurality of pressure cylinders that load the upper roller through pressing rods. Correspondingly, the upper roll is generally mounted floating. The fibro...

Embodiment Construction

[0020] According to the figure, the compressed-air driven pressure cylinder has a cylinder housing 1 in which a piston 2 is movably mounted. A piston rod 3 protrudes from the piston 2 . The piston rod 3 protrudes from a bottom-side bore 4 of the pot-shaped cylinder housing 1 . The bore 4 also serves as the inner wall of the cylinder housing 1 that guides the piston 2 with the piston rod 3 . The piston rod 3 cooperates with an upper roller 5 of a stretching mechanism for the fiber material (for more detailed technical details of the stretching mechanism, refer to the prior art discussed at the outset). The pot-shaped cylinder housing 1 is closed at the end facing away from the bore 4 with a cylinder bottom 6 . The connection between the cylinder housing 1 and the cylinder bottom 6 is designed in this embodiment as a snap-fit ​​connection. The cylinder base 6 has a pressure medium connection 7 for supplying the pressure chamber 8 of the pressure cylinder with air. A guide re...
