    1300 Model Swing Shear Type Cut To Length Line


    12T capacity 1300 model swing shear cut to length line

    It equips with swing shear so it can cut strips into trapezoidal blanks which are widely used in stamping auto parts area, metal electrical appliances parts etc.

    It has advantages of cost saving, space saving, high efficiency etc. if just cut into trapezoidal shape blanks than blanking by punching machine blanking line, as it cost much higher of punching machine than swing shear machine.

    Main components of the cut to length line

    1. One set of NCHW2-1300A model 3 in 1 uncoiler straightener feeder.

    2. One set of swing shear.

    3. One set of conveyor belt.

    4. One set of auto stacking system.

    Coil was loaded, lifted and installed on decoiler’s mandrel by the auto loading car, then decoiler payoff strips and insert strip head into straightener feeder part, electric adjust straightener gap device to adjust straightening performance automatically then feed strips to swing shear after processed by straightener feeder part. Next, swing shear cut strips to required trapezoidal shape, next, the blank were carried out by the conveyor belt and come to auto stacking system.

               1 For NCHW2-1300A model 3 in 1 uncoiler straightener feeder

               1.1 12T Uncoiler

    • 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 loose problem.
    • Components included: expansion and contraction part, press arm part, limit wheel part, material loop controlling part.
    • Material width: 70-1300mm;
    • Loading capacity:12T
    • Coil OD: Φ1000mm~Φ1600mm
    • Hydraulic slide block expansion mandrel, spindle expansion range: Φ470-Φ530mm. It can support and expansion heavy coils over 12Tons.
    • Hydraulic tailstock arm device. It was used to hold one end of mandrel’s main shaft, so as to it has enough loading capacity of the decoiler.
    • Spindle driven motor: AC motor, with frequency converter. 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 frequency converter.
    • 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 tightening metal strip, to prevent coil loosing.
    • Press material wheel adjusting method: through change angle of press arm to change encoder feedback single to adjust speed.
    • Press arm moving method: driven by hydraulic cylinder, can be opened or closed manually.
    • Limit arm device: located on decoiler’s right part, can be rotated along with any external force, for preventing coil of side slip while payoff.
    • Limit wheel motion: outer limit wheel is doing open/close motion driven by air cylinder, internal limit wheel without open/close motion, just move along direction of coil width, outer limit wheel just can be operated by touch screen in manual version, while automatically working, it need to be closed, then can meet safety requirement of before working.
    • Surface process of limit wheel: high frequency with parkerising for rust protection.
    • Material loop control: through induct material loop to feedback signal by the infrared photoelectricity induction switch under press arm, to control uncoiler spindle of start/stop, to ensure enough buffer material loop between uncoiler and straightener.

    1.2 Loading car:

    • Function instruction: be used for moving coil to spindle of uncoiler smoothly, while uncoiling and entry the material head into straightener, it is used for supporting material head to let it entry into straightening roller smoothly, loading car is equipped with backup plate to prevent coil slipping off from loading car while moving little big distance, while hanging coil.
    • Loading capacity: 12T
    • Loading car moving method: hydraulic motor.
    • Loading car lifting method: hydraulic method (controlled by pressure retaining valve, stable and reliable).
    • Moving method of backup plate for preventing slipping down:  by manual.

    1.3 Straightener-Feeder part

    • Function instruction: use unbending principle to release material bending stress to straighten plate, then feed into press equipment according to set length and speed.
    • Bend arm device. Strip head was assisted by support arm and then press down by press arm device, then motorized rollers feed strip forwards to go through straightener feeder part.
    • Driven method: AC servo motor+ speed reducer: 11.0KW PHASE, ITALY
