automatic feeder for power press stamping press feeder for Gantry press

Decoiler

 Function instruction: uncoiling is to fix coil on the spindle of uncoiler, a supporting table to support coil Inner diameter, while working automatically, through material loop controlling instruction to make spindle uncoiling and loosing coil intermittently, equipped with coil diameter detection, to control uncoiling speed, ensure uncoiling line speed is uniform velocity, improved material loosing problem.

 Components included: expansion and contraction part, press arm part, limit wheel part, material loop controlling part.

 Expansion method: hydraulic expansion.
 Spindle expansion range: Φ450-Φ530mm.
 Spindle driven motor: AC motor, with inverter.
 Spindle driven method: variable frequency gear motor.
 Spindle brake: disc brake.
 Spindle uncoiling direction: down uncoiling.
 Press material wheel specification: PU rubber tires
 Press material wheel driven method: AC motor, with inverter 

 Function of press arm: from cut off bundling belt which is used for fixing coil until the coil head is pressed tightly by straightener roller, to prevent coil rebounding; while whole feeding line working, let the coil uncoiling smoothly, to prevent coil dispersing and the press arm is motorized, with tracking and follow up function ie. Rotating speed of press arm roller is absolutely the same with uncoiling line speed, then tensioning metal strip, to prevent coil loosing.

Leveler Feeder 

 Function instruction: use unbending principle to release material bending stress to straighten plate, then feed into press equipment according to set length and speed.
 Driven method: AC servo motor
 Straightening-feeding roller combination: straightening roller; assistant roller; feeding roller.
 Straightening measure display method: dial display.
 Straightning roller release method: pneumatic release.
 Straightening measure adjusting method: manually by hand wheel (Electrically Adjust for optional)
 Straightening measure adjusting method: electrically adjust (for optional), no need rotate the hand wheel, more precise, with date storing function to store each group of material of straightening adjustment date which can save time for future using, convenient for operation.

 Roller driven method: gear driving, all gears adopt tempering, carburization, high frequency quenching, precise grinding gear IT6 level precise standard.

 Straightening-feeding rollers flip up system (for optional): upper straightening-feeding rollers can be lifted by hydraulic cylinder from one side, lifting angle can reach up to 30 degree. Through operating touch screen HMI or button of hand operating box to open straightening-feeding rollers, by this way, easy for clear rollers, to ensure material surface flatness and cleanliness. Adopts double oil cylinder to control.
