Machine performance and structural characteristics

4.1 Machine performance

• New rigid design and finite element optimization analysis to minimize the impact of bending deformation on workpiece quality.
• The machine is equipped with the imported hydraulic system of from Germany, which effectively ensures the high-speed, high-efficiency, reliable and stable operation of the machine
• The new style design of the simple style, the appearance is beautiful and elegant, and the painting is made of Aksu paint imported from the Netherlands

4.2 Machine structure

• All steel plate is welded integrally and has strong earthquake resistance
• Using a large tempering furnace to eliminate stress, good stability, and the frame will never deform
• The frame is formed by the Spanish pentahedron machining center at one time, which ensures the parallelism and verticality of each mounting surface
• There is a “C”-shaped plate mechanism at the throat of the rack to directly detect the distance between the upper and lower molds to ensure the accuracy of the parts.

4.3 Hydraulic system

• Using the most advanced full-closed electro-hydraulic servo synchronous control system, it can achieve high speed, high precision and high efficiency performance
• The hydraulic control system is imported into Germany REXROTH or HAWE company, and the hydraulic system control is stable and reliable
• Y1 and Y2 can be programmed separately, can work under eccentric load condition, or can be tapered;
• The bottom dead point has pressure holding time, programmable to ensure the accuracy of different parts;
• With slow return control function, the operator can control the workpiece better
• Using Italian GIVI linear magnetic scale, high-precision guiding system, position measuring system and hydraulic equalization function, can meet the processing needs of full-length or eccentric load;
• The inner seal of the cylinder is Austrian SKF, which has strong sealing and long service life;
• The hydraulic system pipe fittings and joints are imported from abroad, with good quality and strong performance;
• The hydraulic system has overload overflow safety protection
• The oil level is clear and intuitive;
• The machine tool can work continuously under the rated load, and the hydraulic system guarantees no leakage and the processing is stable and high precision.

4.4 Backgauge system

• Backgauge has fast speed and high precision
• X, R axis adopts ball screw drive, linear guide, Digital AC servo motor drive with retraction control function;
• The three fingers move along the double linear guides to the left and right, with high precision;
• With a unique finger structure, each finger can be moved up and down through  the handwheel

4.5 Electrical system

Electrical components adopt imported or joint venture products, comply with international standards, safe and reliable, long life, strong anti-interference ability, electric control cabinet has heat dissipation device;

4.6 Crowning system

The lower worktable is equipped with mechanical deflection compensation device to compensate the closed-loop control. The control precision is high. The compensation amount is automatically calculated and set by the numerical control system to ensure the consistency of the full-length bending angle

4.7 Controller

• DELEM DA53T CNC system
• 10.1-inch high resolution TFT color display
• Maximum 4 axis control (Y1,Y2 and another two axis)
• Industrial touch screen
• Internal storage capacity 1GB
• Tool library, 30 upper molds, 30 lower molds
• USB storage interface, RS232 interface
• One-page parameter quick programming, navigation shortcuts
• Automatic calculation of table deflection compensation
• Digital programming
• Micro switch panel
• Automatic calculation of bending pressure, mold safety area
• Run analysis tools online
• System diagnostics
• Real-time WINDOWS CE operating platform to ensure the stability of system operation and support instant shutdown

4.8 Tool clamping

• Upper mold clamping method: Yawei quick clamping,
• Upper mold: 1 set of standard straight knife (code 10.105, length 515mm*5), high precision, interchangeable
• Lower mold: 1 set of standard 2V lower mold (code 20.252, length 515mm*6), high precision, interchangeable
• Lower mold clamping method: 1 set of T-type quick mold change pad (code 20.603, length 515mm*6)

4.9 Other configurations

Two left and right support racks that can be adjusted by step, with rotation function to avoid interference when the workpiece is bent (see the figure below)
