How to adjust Hydraulic Swing Beam Shear 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 Swing Beam Shear BladeGAP = 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:
- After first cutting, we shall check cutting edge performance. We may need to increase or decrease to improve edge performance.
- For Harder plate material, we shall use high chrome and harder shear blades, like Cr12MoV, H13;
- 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.
- For CNC Hydraulic Swing Beam Shear, we can directly adjust blades gap on CNC controller. while for manual metal plate shear, we can adjust blades gap by adjust handle manually.
-
How to adjust Hydraulic Swing Beam Shear cutting angle / rake angle?
- Only Hydraulic guillotine type Hydraulic Sheet 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.
-
How to Exchange Hydraulic Swing Beam Shear blades and how to sharp blades edge?
- For Hydraulic guillotine shear, top/down blades has 4 cutting edge. for Hydraulic Swing Beam 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.
