Screw clamp for work pieces of soft material has protective plastic liners held by permanent magnets on clamp surface of clamp jaw and on clamp plate

摘要

The screw clamp has a fixed metal clamp jaw (3) and a relatively moveable metal clamp plate (6), both on a clamp rail (2). A protective liner (10) is fastened detachable via an imbedded permanent magnet (15) to the clamp surface (4) of the clamp jaw and to the clamp plate. The liner is of plastic, and is plate-shaped, and its outer dimensions are larger than those of the clamp surface, to increase pressure distribution on a clamped work piece (11).
