THE WHOLE STRUCTURE OF THE PRESS BRAKE:
- Totally European design, streamlined looking
- Taking off the inner-stress of welded parts by tempering, good stability
- Remove rust with sand-blast and coated with anti-rust paint
- Primapress adopts Europe technology and The body of the bending machine is first welded, and then processed by the gantry machining center to ensure the accuracy and stability of the machine, leading the domestic counterparts! This manufacturing process is firstly developed by Primapress in Bowang!
- Three dimensional finite element analysis and optimization design are adopted for the main components.
- Adopt Spanish pentahedron machine center, once clamping can finish all working surfaces which will guarantee dimension precision and position precision.
- The design of the machine frame is a critical part of any machine with relation to its ability to produce accurate parts for a long period of time.
- Frames, assembly surfaces and connection holes are machined after the welding process, up to 6o’ in a single pass.
- Supplying three front sheet supports, Finish of Nippon Polyurethane paint.
- The top plate connections are mounted with double springs as well as spherical connections to the cylinders with double safety.
- The parallelism with the top plate can be adjusted more precisely and the proportional valves can work synchronously with each other.
- All seals in the cylinder are imported, the most famous brand, good quality and high performance.
Upper stroke design for bending, low noise, stable operating situation, Parallel tolerance of Y1 and Y2 is 0.01mm. Y1, Y2 can be programmed separately can work under non-balance load, can bend cone-shape work piece. At the bottom dead center a pressure-keeping time is offered and can be programmed to assure the precision of all kinds of the workpiece. Can move the ram up slowly, which allows the operator to control workpiece conveniently. Universal fixing-surface of the upper tool can be meeting with the clamping requirement of the tool farthest!
- Close loop electro-hydraulic synchronized servo-control system, the most advanced.
- Overload overflow protection is outfitted to the hydraulic system, which can assure no leakage, and the oil level can be read or seen directly. Being able to work under rated load continuously, stable working and high precision.
C-TYPE THROAT DEFORMATIONCOMPENSATION DEVICE
Accurately measure the small deformation caused by the bending force of the machine tool and feedback compensation to ensure the bending accuracy of plates of any thickness and material.
OPTICAL SAFETY GUARDS
Italy MSD and Cermany DSP Laser protections
The laser protection device imported from Italy can comprehensively and effectively provide safety protection for the bending machine and protect the personal safety of the operator.
CROWNING COMPENSATION, TO AVOID RIGHT CONDITIONS
Low worktable has an automatic crowning compensation uint; the compensation amount is automatically setup by the CNC system, with the guarantee of the same bending angle on full length.
The worktable adopts the particular design, reducing the crowning distortion amount of lower too effectively.
The new generation press brake controls offer an even higher grade of efficiency in the programming, operation and control of today’s press brakes.
ELECTRICAL SYSTEM, SCHNEIDER ELECTRICAL
Electrical components are imported or from a Sino-foreign joint Venture, in accordance with international standards, reliable safety. long life, and good anti-interference ability, and a radiation unit is fitted in the electrical cabinet. Having a movable single-hand pedal switch with an emergency stop, easy to operate.
CNC BACK GAUGE
- Good for workpieces needing multiple steps of bending with high precision requirement.
- X is moved with ball screw, guided by the linear guide, and driven by digital AC servo-motor
- back gauge has well enough mechanical strength and rigidity with tank-type gauge structure
- Two fingers are moving alone swallow guide, operate easily with high precision
- Particular finger-stop design, enlarge the range of back gauge
