GMC Magnetic Box & Pan Brake: BB-4816-MAG

  • Electromagnetic sheet metal bending machines use an electromagnetic, rather than a mechanical, clamping system. The machine consists of a long electromagnet with a steel clamp bar located above it. The sheet metal is clamped between the two by an electromagnet capable of clamping with a force range of between 3-10 tons. Rotating the bending beam then forms the bend. The sheet is bent around the front edge of the clamp-bar.
  • Using the machine is simple, slide the sheet in under the clamp-bar; press the start-button to initiate clamping; lift the handle to form the bend to the desired angle; and then return the handle to automatically release the clamping force. The folded sheet can now be removed or repositioned ready for another bend.
  • The special centre less compound hinges, are distributed along the length of the bending beam allowing bending loads close to where they are generated.
    The combined effect of the magnetic clamping with the special center less hinges means that the electromagnetic sheet metal bending machine is a very compact, space saving, machine with a very high strength-to-weight ratio.
  • The electromagnetic sheet metal bending machine are highly versatile sheet metal folding machines used to bend mild steel and aluminum sheet metal. Thickness of up to 1.6 mm thick can be folded across the full length1250mm.
  • The magnetic clamping system replaces the bulky clamping structure used in conventional folding machines. The small compact clamp bar does not hinder or obstruct the work piece. Automatic electromagnetic clamping and unclamping, means faster operation. This machines have a much greater versatility than conventional sheet metal benders. The machine is ideal for use in the sheet metal industry, air-conditioning and building industries.
  • An electrical interlock is offered to enhance operator safety. This operation ensure that a safe pre-clamping force must be applied before full-clamping can be engaged.
