Flanging Machine

DESCRIPTION OF THE MACHINE:
This machine has been studied for the execution fo the heads of tank bottoms and it essentialluy consists of:
- A basic structure and a top struction made of electro-welded  steel plates, thermally treated for welding stress relieving. The structures are thenstiffly mounted so to obtain the structural assembly of the machine which assures high sturdiness and, therefore, stability during flanging, slides for bottom-holder and bottom blocking carriages are fitted in the basic structures and in the top one ( for machines suitable to work thickness over 15mm)
- Motorised lower bottom-holder carriage which supports the bottom during glanging which translates on screws on the carriage, it is fitted a hydraulic cylinder which allows height adjustment for bottom positioning.
  
- Motorised top-bottom blocking carriage, bnecesary to block the bottom against the lower carriage. It is equipped with a hydraulic cylinder and translated on screw.
- The shaped roll, built in high resistance steel, induction hardened with remarkable hardening depth, properly shaped according to the radius of the edge to be obtained, this roll is motorised by means of a radial pistons motor and it is equipped with infinitely variable rotation speed.
- The flanging roll, built in the high resistance steel, induction hardened with remarkable haredning depth. Pushes by means of a system consistong of hydraulic cylinders, the bottom plate against the shaped roll. This operation may be done in manual or in automatic.
- The bottom supporting rolsss, positioned underneath the shaped roll, support the edge of the bottom during the flanging.
- Hydraulic system consists of motor pump group, oil tank, equipped with filter (with anti-clogging signal, level gauge, thermostat, oil water heat exchanger and group of valves and solenoid. Valves for the correct machine operation and safety. Main Pump for shaping roll rotation is with variable capacity hydraulic components: REXROTH-BOSCH - Duplomatic or similar quality brand.
- Electrical system consists of: Main board, containing the power and protection components and the trasnformer, electric components: Telemecanique Siemenrs Nais or similar quwlaity brand.
- Control panel: Places on the machine side so that it allows the operator to see very well the flanging zone: it is complete with:
    * Starting key
    * Warning lights
    * Emergency
    * joysticks and push-bottons
  for the correct and complete machine working.
