Ferromagnetic workpieces
SMC magnetic gripper offers more holding force
When transporting ferromagnetic workpieces with irregular surfaces, vacuum applications quickly reach their limits. The new MHM series magnetic grippers from SMC offer increased holding force without deforming the material.
Companies across all industries use pick & place applications for ferromagnetic workpieces in their production processes. As the surfaces of the parts to be moved are often corrugated, perforated or simply uneven, magnetic grippers that offer a high holding force must be used in this case. SMC has further developed its MHM series magnetic grippers and increased their maximum holding force in order to hold workpieces even more precisely and always be able to react dynamically to different applications.
More force for safe handling
If sheets, metal plates or other workpieces with ferromagnetic properties need to be moved, the new magnetic gripper from SMC does the job with greater precision and safety: available in various sizes, the solution achieves a magnetic holding force of ten to 1,000 newtons with different piston diameters. This ensures continuous protection against falling, even if the compressed air supply is interrupted.
Flexibility for different workpiece sizes is also ensured by an adjustment screw on the top, which defines the distance between the magnet and the workpiece and therefore the attraction force. This can be set between 230 and 1,000 newtons for a piston diameter of 50 millimetres, for example. In addition to a firm hold, the adaptability also ensures that a workpiece is not deformed by excessive force or that a second part is unintentionally picked up.
Thanks to the dimensions of 30 x 30 x 40 millimetres (50 Newton) to 70 x 68 x 80 millimetres (1,000 Newton), the size is space-saving. This means that several magnetic grippers can easily be arranged in parallel to transport parts with a large surface area. The new MHM series also works pneumatically: compressed air from above moves the piston and magnet downwards to pick up and hold the workpiece. To set it down, compressed air is applied to the underside of the magnetic gripper, which pushes the piston and magnet upwards again, releasing the workpiece.
Various mounting options make the magnetic gripper from SMC a flexible partner for pick & place applications: Housing threaded holes on the cylinder head and on the side allow the solution to be mounted axially or laterally. Axial installation is also possible in a centered position using an adapter. The magnetic field-resistant electronic signal transmitters for high process control and the hoses for the compressed air can be attached from two sides. A rubber ring made of fluororubber on the cylinder head, which can be replaced without tools, ensures that the surface of the workpiece is protected. as
