Hydraulic Sheet Metal Shearing Machine 8mm

QC12K hydraulic shearing machine

for plate cutting, we can use plasma or torch, but Hydraulic Sheet Metal Shearing Machine is better selection. The cutting edge will be with less heat stress and smooth. The parts can be directly used for product. Swing beam shear and guillotine shear have same cutting performance. while SWB shear's cutting angle is fixed, easy for electric and hydraulic maintanence. standard machine is with 6GrW2Si cutting blades. high chrome blades are optional. CNC controller can be E21S or DELEM series, can be with Ac inverter motor or servo motor for easy operation and good positioning.

TECHNICAL FEATURES

  • High quality plate welded structure will provide Hydraulic Sheet Metal Shearing Machine with high rigidity and shearing accuracy; welded shearing machine body is vibration stress released.
  • Hydraulic Sheet Metal Shearing Machine triangle stable welded top shearing beam swing up down around self-aligning bearing;
  • NC Hydraulic Sheet Metal Shearing Machine control system can program on back gauge (1 Axis) or blades gap (optional);
  • Normal Hydraulic Sheet Metal Shearing Machine is with T screw. NC Hydraulic Sheet Metal Shearing machine’s Back gauge is equipped with high accuracy ball screw;
  • Swing-up back gauge system for shearing longer pieces than maximum back gauge range;
  • NC Hydraulic Sheet Metal Shearing Machine Back gauge has retract function. During sheet cutting, the back stop will keep safe distance to sheet metal to avoid scratch and dimension error;
  • The Sheet Metal Shearing Machine hydraulic system includes valve block, lower noise and high efficient gear pump, left/right hydraulic cylinders.
  • With hydraulic hold down system, metal plate will be fixed during cutting. The hydraulic hold down cylinders are with Polyurethane protection to avoid hurt the plate surface;
  • Electric and hydraulic system overload protectionqc12k-8 hydraulic shearing machine swing beam
  • Hydraulic Sheet Metal Shearing Machine blades is made from special alloy material with proper heat treatment; For mild steel plate, shear blades material is 6CrW2Si. for Stainless plate, Blades material can be Cr12MoV or H13.
  • Two cutting edges on top blades; four cutting edges on down blades;
  • Movable foot switch control plate shearing, with emergency stop;
  • Front support arms are with 90 degree guider,  ruller, T-slot and flip-stop;
  • Hydraulic Sheet Metal Shearing Machine Working table is with ball or roller transfers;
  • Shadow line facility with fluorescent lighting;
  • Front finger protection, rear protection fence and side throat guards
  • Hydraulic Sheet Metal Shearing Machine Oil tank is with level and temperature indicator.

  1. How to adjust Hydraulic Sheet Metal Shearing Machine blades gap?

    To cut metal sheet , we shall set proper up / down blades gap. The proper shear blades gap will affect on cutting force and plate cutting edge. For low elongation metal plate, we shall use smaller gap.
    Hydraulic Sheet Metal Shearing MachineBlade 

    GAP = K * t (plate thickness)

    • Mild steel (Q235, Q345): K = 0.1
    • Stainless steel (201, 304, 316):  K = 0.06~0.08
    • AL, copper : K = 0.6
    • Weldox (700, 900, 960): K = 0.12~0.16
    • Hardox (400 ): K = 0.16~0.18

    NOTE:  

    1. After first cutting, we shall check cutting edge performance. We may need to increase or decrease to improve edge performance.
    2. For Harder plate material, we shall use high chrome and harder shear blades, like Cr12MoV, H13;
    3. For harder material cutting, we shall use higher capacity shearing machine. The cutting force can be 2 times than mild steel for SS plate, Or even more for other harder plate. We shall keep blades edge sharp during cutting.
    4. For Hydraulic Sheet Metal Shearing Machine, we can directly adjust blades gap on CNC controller. while for manual metal plate shear, we can adjust blades gap by adjust handle manually.
  2. How to adjust Hydraulic Sheet Metal Shearing Machine cutting angle / rake angle?
    • Only Hydraulic guillotine type metal plate shearing machine’s cutting angle is adjustable. For swing beam shear, top beam shearing angle is fixed.
    • Hydraulic guillotine shear’s cylinders are connected in series. It means big cylinder down chamber is connected with small cylinder’s top chamber by hydraulic pipe or hose.  Increase or decrease oil volume can adjust small cylinder’s relative position of small cylinder. so that we can adjust shearing angle.
    • On control panel, turn the key switch to angle, push increase or decrease button to adjust shearing angle.
    • For thin plate, smaller shearing angle can reduce edge twist. For bigger thickness plate, bigger shearing angle can reduce cutting force needed.
  3. How to Exchange shear blades and how to sharp blades edge?
    • For Hydraulic guillotine shear, top/down blades has 4 cutting edge. for swing beam type shear, top blades have 2 cutting edge, bottom blades have 4 edge. we can directly take off blades and change cutting edge. Before use the machine, we shall make sure that the blades are fixed and gap even. otherwise, we may damage the blades.
    • When all blades edge is not blunt. We shall take off the blades complete (top / down). Put all same set blades over surface grinder to sharp them. we must make sure same set blades thickness is equal.
    • Shearing machine’s top blades are fixed by bolts only. bottom blades are fixed over square block. We must calibrate shearing gap before working. method is different for different model machine. consult our engineer for detail.
