During the utility model work, aluminium foil or Copper Foil coiled strip are sleeved on outside the swelling bar on the barrel, HM Hydraulic Motor can drive screw mandrel and rotate, screw mandrel promotes the nut motion, nut promotes slide block and extends radially out along barrel, compress mutually on the wall of swelling bar and the hollow parts at coiled strip center, make coiled strip be fixed on the material axle, unreeling in the process of coiled strip, can make HM Hydraulic Motor be in the fuel feeding state all the time through the fuel feeding swivel joint, HM Hydraulic Motor can be rotated with barrel, swelling bar and coiled strip are in the swelling state all the time, compared with prior art, the utility model need not tighten up the swelling bar in the process of unreeling, and the swelling bar can keep constant tension force in the whole process that unreels, in addition, when the loading and unloading coiled strip, only need the modulated pressure motor to turn to and can realize extending radially out and withdrawing of swelling bar, can realize this automatic guidance.The utility model is applied on the air-conditioner fin manufacturing line, can improve the work efficiency of whole production line.
For avoiding the nut limit of moving, improve the reliability of service of device, the both sides that are positioned at two nuts in the described barrel are provided with stop collar.When the screw mandrel drive nut moved to and conflicts with stop collar, nut no longer moved, and can play the safety guard-safeguard effect.
For avoiding in the use barrel distortion, the end of described barrel external part is provided with strut bar, is connected through the strut bar bearing between the end of strut bar and barrel external part.When changing heavier coiled strip over to,, can avoid the barrel distortion because they sup-port is arranged.
For slide block can successfully be withdrawn, the section of described webge slot is T-shaped.Certainly, the section of webge slot also can be trapezoidal other shapes that waits, and when nut moves, can release and retract slide block in the radial direction.
