Model 3212-SA-2P Tube End Forming Machine

HIGH AND MEDIUM PRODUCTION TUBE/PIPE END FORMING Two palm button semi-automatic form cycle, this economically priced unit is ideal for quality production of tubing that requires end finishing.  This unit  will reduce, expand, bead, flare or flange.  Simply utilizing the proper tooling, many shapes take form.  This rugged and powerful unit generates up to 30 tons of clamping and forming forces.  It is completely self contained with quality hydraulics and electronics.  An air supply is used to operate the tube stop assembly.  This assembly in conjunction with the micro switches will insure precise form depth or height.  The powerful hydraulic clamp assembly will insure that the tube being held for forming will not slip and the surface will be mar free.  Two 24 volt palm buttons control all hydraulic movement.  A programmable logic control system allows for manual or semi-automatic form cycle.  A typical production run would be as follows:  Tube stop assembly and micro switches are preset   Place tube into clamps and up against the tube stop. Simultaneously depress the 2 palm buttons and hold until cycle is complete. (5-15 seconds, depending on shape, form and customer requirements)   Cycle: Depress two palm buttons. Clamp closes. Tube stop retracts. Cylinder advances and forms and makes micro switch and stops. Cylinder retracts and makes micro switch. Clamp opens. Remove part.  Tube stop arm will automatically re-position for another cycle.

HIGH PRODUCTION HIGH QUALITY AT LOW COST The model 3212-SA-2P is a completely self-contained end forming machine.  It requires a supply of shop air to operate the tube stop system.  The machine is normally shipped without hydraulic fluid.  First add fluid, plug it in, hook up the air supply and you’re ready to start production.  The model 3212-SA-2P has the capacity to expand, reduce, flare, flange, dome and bead as well as other special applications with development.  Note the ideal positioning of the critical components such as the adjustable tube stop assembly, the clamp collars, the forming tool and the adjustable 12 volt micro switches.  All of these important features are conveniently located and can be moved, changed or adjusted with ease.

The hydraulic clamp is raised and lowered on 2 shafts 2” in diameter. Larger diameter shafts are used for higher tonnages. Clamp dies are retained with socket head screws and reinforced with backup plates and 2” welded gussets for added strength.

All tooling is manufactured from tool steel and heat treated to more than Rockwell RC-62. In some applications tooling is also nitrated for longer wear life. In most applications, clamp sets are capable of forming two diameters for greater versatility and economy.	The tube stop assembly is operated by a pneumatic rotary actuator. A proximity switch insures that the arm is retracted before the form cylinder can advance, eliminating potential damage.
