HBC-EA120 EH Machine

Three Stations, Three Power Packs, One Machine

The HBC-EA120 gives each station its own 1.5 kW power pack. Cutting, punching, and bending do not have to take turns: while one operator bends a busbar, another can punch or cut the next one. This keeps the machine busy and shortens the time a batch spends on the floor.

Because every station has its own drive, there is no need to switch between operations. Each job starts as soon as the bar is in place, which is where the HBC-EA120 gains its speed over a single-pack machine.

The bender delivers 220 kN, and the cutter and the puncher deliver 160 kN each, at hydraulic pressure up to 200 bar. The machine rolls on wheels and needs a footprint of 2,370 × 1,100 mm, with a height of 1,720 mm and a weight of 700 kg.

Precision in Bending, Punching & Cutting

The HBC-EA120 is designed to deliver consistent and repeatable results across bending, punching, and cutting operations, helping operators achieve accurate busbar fabrication from one part to the next.

Bending Accuracy & Repeatability

Busbar bending accuracy can be affected by material thickness, alloy composition, and the natural spring-back of copper and aluminum. To compensate for these variables, the bending system uses a 3600-pulse encoder for precise angle measurement and control.

The bending process is performed in two controlled stages. After the initial bend reaches the programmed angle, the system compensates for spring-back through a second controlled movement, helping achieve the required final angle with greater consistency.

A digital ruler with 0.01 mm accuracy is also used along the bending axis to monitor piston movement. Once the correct piston position for a specific busbar thickness, alloy, and target angle has been established, the value can be stored and reused for repeat production. This significantly reduces operator dependency and improves repeatability from one busbar to the next.

Punching Position Accuracy

The punching section is designed for accurate hole positioning in both longitudinal and transverse directions, with hole spacing held to ±0.1 mm. Round holes from Ø4.5 to 20 mm can be punched, and the punching pattern stays consistent according to the required dimensions, supporting accurate alignment during subsequent assembly of the busbar.

Cutting Accuracy & Edge Quality

The cutting section provides accurate longitudinal positioning to produce busbars at the required length, up to 4 m. The cutting system is designed to create a clean, burr-free cut without unwanted excess material, reducing the need for secondary finishing and preparing the busbar for the next fabrication or assembly stage.

Consistent Results, Less Operator Dependency

By combining controlled bending, accurate punching positioning, and clean cutting, the HBC-EA120 is designed to improve repeatability throughout the complete busbar fabrication process while reducing the influence of operator variation.
