CNC Sheet Metal Press Brake machine 80T

CNC sheet metal press brake machine 80t

Sheet Metal Press Brake WE67K-80T is very common capacity sheet metal bending machine for thin plate fabrication, like elevator factory, metal door production factory, or other general machine cover making. Standard machine is with developed CNC control system, world reputation hydraulic system, servo motor and ball-screw driven back gauge. the CNC press brake has characters of high working speed, high accuracy, lower noise, operation people and machine self protection. The big advantage of this type sheet bender is that we can install different tooling on different section, unbalance bending is perfect.

SHEET METAL PRESS BRAKE TECHNICAL FEATURES

  • European Sheet Metal Press Brake machine controller, with full CNC controlled Y1, Y2, calculation based on material and tool library;
  • Automatic bending procedure optimization by CNC Sheet Metal Press Brake‘s controller, engineer can adjust the steps according to actual design;
  • Y1, Y2 is measured with high accurate optic scalars. Measured signal will be feedback to Sheet Metal Press Brake CNC controller timely.
  • European proportion valves will control left and right cylinder’s movement according to controller’s command.
  • CNC Sheet Metal Press Brake machine Back gauge is with long pitch – precision ball screw and liner guide. Moving speed is higher; repeat accurate is higher;
  • Back gauge is driven by servomotor for X-axis. There are optional R, Z-axis.
  • Back stop fingers are with two steps, which will convenient for various part fabrication;
  • Ram guide is with low friction Polymer wear-resistant materials, which will give CNC Sheet Metal Press Brake long accurate working life;
  • Working table is with automatic crowning system. Hydraulic type is for up to 200T-3.2m Sheet Metal Press BrakeWE67K-80 CNC hydraulic press brake machines, while wedge structure is applied for bigger machines.
  • For bending force up to 200T, quick clamp for punch is applied. It will be easy handle the up tooling. The clamp has wedge crowning adjust system.
  • Side and rear protection fences are standard for up to 200T Sheet Metal Press Brake machine. For bigger machine, optic safety sensor will be optional.
  • Low noise and high efficient gear pump is standard Sheet Metal Press Brake configuration;
  • Ram is with Anti-tilt device for machine protection;
  • CNC Sheet Metal Press Brake Oil tank is with level and temperature indicator.
  1. Estimate Bending Force Calculation or Max Bending Thickness for CNC Sheet Metal Press Brake

    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 Sheet Metal Press Brake 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 (CNC Sheet Metal Press Brake 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. MAIN COMPONENTS COOPERATORS OF JINQIU CNC SHEET METAL PRESS BRAKE MACHINE:

    jinqiu hydraulic press brake components

    • DELEM : Netherlands, Was established in 1976, No.1 brand supplier for hydraulic CNC press brake machine and hydraulic shearing machine controller. Controller includes DA52S, DA56S, DA66T, DA58S;
    • Rexroth: BOSCH Group is world biggest hydraulic components (valves, pumps) supplier. Our all hydraulic CNC synchronise press brake are with the valves / pumps.
    • NACHI: Japan,  was founded in 1928, world famous brand for high volume, high pressure gear hydraulic pumps. All our hydraulic CNC press brakes machine over 300T are with NACHI pumps;
    • HEIDENHAIN: Germany, established in 1889. Optic scaler is is most accurate measurement, higher accuracy and stability than other scaler.
    • NOK: Japan, was setup in 1939, biggest Group company making hydraulic seals in Jappan;
    • HIWIN: Taiwan, was setup 1989, leading supplier for transmission system, Includes liner guide and ball screws;
    • FIESSLER: Germany, was founded in 1956, leading supplier of CNC press brake machine safety system.
    • ESA: Italy, was established in 1962. One of very common sheet metal press brake machine controller supplier in the world.
  3. CNC Sheet Metal Press Brake Shipment, Unloading, Installation Related Issues
    • The CNC Sheet Metal Press Brake 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 Sheet Metal Press Brake 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 Sheet Metal Press Brake, 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 Sheet Metal Press Brake 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 Sheet Metal Press Brake, 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.
