The LT fully-automatic busbar punching, bending and cutting machine runs three independent hydraulic units at once, so punching, shearing and bending proceed in parallel instead of one after another. A servo-controlled cutting unit sets length automatically and leaves a flat burr-free cut face, while the bending system calculates developed length itself. Two frame sizes cover 300 kN and 500 kN duties for South African panel shops moving from manual to automated production.
Test conditions: Copper busbar, three units driven simultaneously with automatic positioning coordinated by servo motor, PLC and touch screen.
Measured values: Model LJMC-303E-3-S nominal force 300 kN and model LJMC-503 E-3-S nominal force 500 kN; punching diameter range ⌀4.3–⌀25 mm and ⌀4.3–⌀30 mm; maximum thickness 12 mm and 16 mm; motor power 3 × 4 kW and 3 × 5.5 kW.
Benchmark: The 500 kN frame adds 4 mm of thickness capacity and 5 mm of punching diameter over the 300 kN frame — the deciding spec for workshop bar above 12 mm.

This machine is has three processing units of punching, cutting and bending. And it is designed with three independent hydraulic systems, so the punching, shearing, and bending unit can work simultaneously.
The machine realizes the automatic positioning of the three units, through the cooperates with each other of servo motor, PLC and touch screen.
Main Characters:
(1) The cutting length is automatically controlled by servo motor, the incision interface is flat, no waste, burrs and droop.
(2) No need to mark a proofing board for punching. Servo motor automatically locates punching coordinates. It supports continuous punching and punching with different apertures, and supports coordinate input and common template selection, which is convenient and efficient.
(3) The bending system automatically calculates the unrolling length of the copper busbar. High-precision screw guides control the bending length. The system has a variety of built-in bending processing templates; supports multi-segment and multi-angle continuous bending processing.
