Description

B 1.554 Block Cylinders with aluminium or bronze housing for adjustable magnetic sensors

Hydraulic block cylinders are universally used for all linear movements with high force requirements and very small dimensions. With the adjustable magnetic sensors certain
piston positions can be controlled exactly.

The double-acting function ensures high function safety as well as exactly calculable and repeatable stroke times.

The piston of these block cylinders is equipped with a ring-shaped magnet whose magnetic field actuates the sensor.
The cylinder housing is therefore made of a non-magnetisable material.
Two variants are available:

154X X1X: High-tensile aluminium alloy max. operating pressure 350 bar
154X X5X: High-tensile bronze alloy max. operating pressure 500 bar

The magnetic sensors are guided in dovetail slots and allow a continuous control of the piston position.

Application examples

Application example 1

Tools for fabrication of connecting elements for prams

The core-pullers for injection moulding connecting components made out of plastic materials are inserted and retracted by aluminium block cylinders B1.554 for fabrication in exact position.

Application example 2

Tool for fabrication of mobile phone housings

The exact shaping of the inlet for the later installation of the microphone is made during the injection process by dies, which are operated by aluminium block cylinders with magnetic sensors.

Application example 3

Operating core pins

In the figure the core cylinder is located in the main core. The position monitoring supplies the required information about the position of the core pins.
The connection of cylinder and core puller should be effected by means of a coupling pin, because core pullers are usually self-guiding.

Application example 4

Operating core puller plates

The figure shows an item which is made in three versions. The core-pins are driven into the corresponding position by two independently-controlled core puller plates.

Version A core puller plate 1 actuated
Version B core puller plate 2 actuated
Version C core puller plates 1+2 actuated

The core puller plates drive against fixed stops in the front and back position
and are controlled by proximity switches in both positions. This enables an integration into the control of the mould carrier.
The figure shows version A;
Core puller plate 1 is actuated.
Core puller plate 2 is not actuated.

The building height of the foam mould is limited by the mould carrier.
Due to the small and compact dimensions of the block cylinders the core puller plates could be installed in a space-saving way.
