CNC Bending Press Machine WE67K 250

CNC bending press machine we67k 250

For structure steel, harder Wear - resistant steel, We suggest 250T capacity The CNC Bending Press Machine. It can bend up to 10mm mild steel, or 8mm structure steel or up to 6mm Hardox plate. The hydraulic bending machine is equiped with DELEM CNC controller, Bosch hydraulic system, working table automatic crowning system, servo motor-ball screw drive back gauge. Machine body, working table and ram are with high quality steel plate, shot blasting treated, viberation stress eliminated. Our design and machine produce process will warranty long working life of the hydraulic press brake.

  1. Estimate Bending Force Calculation or Max Bending Thickness for CNC Bending Press Machine

    Estimate bending force calculation formula is 

     P=650*S*S*L/V

    • P:  Estimate Hydraulic press Brake Bending force (T)
    • S:   Plate thickness (mm)
    • L:   Bending Length (m)
    • V:   Hydraulic Press Brake Bottom die V opening width (mm)

    NOTE:  

    1. The CNC Bending Press Machine bending force calculation is based on mild steel (tensile strength = 450Mpa). For other material, we shall time constant K (related with material tensile strength, hardness, elongation). for example, Stainless plate characters can be different according to plate number. we can set K=1.5.
    2. Normally V (The CNC Bending Press Machine bottom die V opening width) can be 6 ~12 times plate thickness. for thin plate we select smaller V opening. while for bigger and Harder plate, we shall set bigger V opening. Bigger V will introduce bigger bending radius.
  2. The CNC Bending Press Machine Shipment, Unloading, Installation Related Issues
    • The The CNC Bending Press Machine will be loaded over steel rack. During loading / unloading, we shall pull or push only over the steel rack to avoid deforming on machine body frame.
    • On CNC Bending Press Machine wall frame, there are lifting hook. We shall use enough length steel wire rope or chain to lift the machine by the hook. We shall be careful to avoid machine drop down;
    • For bigger capacity CNC Bending Press Machine, the machine height can be close to container door top. when we pull machine out, we shall be careful to avoid damage on machine top parts. To protect the parts, we may remove hydraulic valve, motor or other components on top. Please reinstall the parts according our guide.
    • The CNC Bending Press Machine will be fixed by chain or steel wires inside the container, covered with plastic film to avoid moisture during ocean shipment.
    • When receive the CNC Bending Press Machine, Customer shall remove the steel rack under the machine, prepare foundation for the machine. Good fix and levelling will make machine work longer and accurate.
