PBE Electrical Servo Press Brake

Ⅰ. General Introduction

High efficiency, high precision, energy saving and environmental protection

● The new “mechanical servo drive system” is driven by a highly sensitive AC servo motor to increase the speed, efficiency and stability of the slider.

● High-speed back gauge also improves the machining speed and accuracy of the machine

● New appearance industrial design, providing a friendly human-machine communication environment

● Higher parameters and configuration, more powerful and easier to operate

● 60%-70% energy saving than hydraulic bending machine, no oil use cost

II.Machine structure 

1. Outline feature

◆ new European design, streamlined appearance

◆ O-frame structure, Stiffness than the average C-type structure to improve more than 50%

◆ The whole steel welding, seismic strong

◆ Large tempering furnace to eliminate stress, good stability, the frame will never be deformed

◆ Machine body is machined with once clamping for all machining surface from Spain five faces machining center, which assure parallelism and verticality between/among surface of the machine body.

◆ Painting imported from the Netherlands AkzoNobel auto refinish

2. Ram feature

◆ Upper stroke design for bending, low noise, stable operating situation

◆ Slider thickening, widening, bending deformation will be reduced to minimum;

◆ Y1, Y2 parallel tolerance of 0.01mm

◆ Y1, Y2 can be programmed separately, can work under partial load condition, also can be tapered bending.

◆ Bottom dead point has dwell time, programmable, to ensure the accuracy of different parts

◆ Slow return control function, the operator can better control the workpiece

◆ Common upper Punch mounting surface, to meet different punch clamping requirements

3. Mechanical transmission system

◆ The most advanced full-closed mechanical servo synchronization control system

◆ Ball screw, screw bearings, timing belt and other sets are Complete sets imported

◆ Use imported grating, high-precision guidance system, position measurement system and servo control function, can meet the needs of full-length or eccentric machining.

4. Back gauge positioning system

◆ This machine is for the production of multi-bend, high-precision workpiece

◆ Back gauge traveling high speed, high positioning accuracy

◆ X, R axis driving by ball screw, linear guide, digital AC servo motor drive, with concession control function

◆ Box-type material retaining beam block structure, with sufficient mechanical strength and stiffness

◆ Unique back gauge finger structure, expanding the stopper range

5. Electrical System

◆ Electrical components using imported or joint venture products, in line with international standards, safe and reliable, long life, anti-interference ability, electric control cabinet with air-conditioning cooling device

◆ Two front sheet supports that can be moving along by linear Guide.

◆ Movable foot switch, easy operation, emergency stop function

◆ Standard have LazerSafe protection PCS-A0-L2S-2.

6. Tooling / Clamp:

◆ Standard Quick Punch clamp.

◆ One set of standard Punch & 2V Die

◆ Worktable for Die is 2V+T shape quick change

7. CNC control system standard is DA53T, DELEM of the Netherlands.
