Demagnetising, gripping and lifting AT Blechexpo in Stuttgart (3-6 November), Goudsmit Magnetic Systems will present a number of plate handling innovations.

tools. Rising demand for higher quality makes work piece demagnetisation increasingly important. Magnetised work pieces attract iron particles. The impossibility to weld magnetised objects is an additional problem. Magnetisation can cause rough surfaces on work pieces after galvanisation, as well as products sticking to each other and causing faults in moulds. An increasing number of companies are fitting

These include additions to its range of magnetic grippers for picking up or holding materials such as stamped steel parts, blanks and perforated plates. The original design was suitable for plate thicknesses up to 6mm; the new version can handle thicker objects, and is three times as powerful, giving a 100mm diameter gripper a shear force of 3,500N. In addition, the grippers can be equipped with sensors that show when the magnet is on or inactive. This is particularly important in robotisation, because it allows better control. Magnet grippers offer a safe working method and there is no need for a backup system to guarantee that the load remains attached. These types of combination grippers can also handle perforated plates and small parts without any modification or change of

replaceable in one piece. There is no need to weld it to the machine or to run it through the tunnel twice, using extra guide rollers. This makes the option to demagnetise work pieces in grinding, sanding or brushing machines available to everyone. Goudsmit Magnetic Systems BV – Netherlands Website: www.goudsmit-magnetics.nl

demagnetisation tunnels into their production lines. In the past, it was only possible to install demagnetisation plates on existing production lines, and plates are often less effective than a tunnel. Because of this, Goudsmit has developed a modular demagnetisation tunnel that combines the installation ease of demagnetisation plates with a tunnel’s efficiency. A major advantage of this is that the transport belt is
