hydraulic busbar processing machine JPSK-303ESK

The image is for reference. Actual appearance and configuration may vary.

Punching force, kN: 300
Maximum busbar, mm: 160 × 12
Work units: Punching, shearing, bending

Three work units for punching, shearing and bending copper or aluminium busbars in one machine.

Punching, shearing and bending units share one hydraulic machine with two work tables. The source describes the units as independent; the permitted simultaneous workflow is confirmed for the actual configuration.

Purpose and distinguishing features

Suitable applications

Production of conductive busbars for switchboards, distribution assemblies and electrical equipment: holes, blank cutting, horizontal bends and vertical bends.

JPSK-303ESK hydraulic busbar processing machine

JPSK-303ESK combines three sequential operations at one workstation. Compare it with separate punching, shearing and bending machines through the busbar range, changeover time and required dies. The 160 × 12 mm limit does not mean every geometry is available across that entire envelope at once.

Choosing a configuration

For selection, send the busbar material, width and thickness, hole and bend drawing, minimum edge distances and required volume. We will check the operations, dies and process sequence.

Hole and bend geometry depends on the installed tooling. Special dies for oval or shaped holes, vertical and U-bending, twisting, embossing and cable-lug pressing are agreed separately.

JPSK-303ESK working limits

The values describe the version in the supplied source material. Material, geometry, minimum edge distances and the matching die are checked before ordering.

Punching, shearing and bending

A six-position turret reduces manual punching-die changes; positioning can use a stop pin, rule or light reference.
The double-column shearing unit uses a double-edged Cr12MoV blade. Edge quality depends on blade condition, clearance and busbar material.
The bending unit supports horizontal, vertical and U-bending with the matching die set. Z-bending uses entered section height and length.
Each unit has a foot control and emergency stop; the delivered machine manual defines the actual safe operating arrangement.

Control and principal components

The source configuration lists a Siemens PLC, Schneider contactors and thermal relays, a Yuken directional valve and a separate hydraulic station. Exact component series are recorded in the final specification.

Source-listed standard tooling

Round punching dies Ø7, Ø9, Ø11, Ø13, Ø17 and Ø19 mm; oval dies 11 × 15 and 13 × 18 mm.
Two horizontal-bending die sets, two vertical-bending die sets and one U-bending die set.
Three foot switches, two limit switches, positioning needle, magnetic stop, oil filler, hexagon key and a hydraulic-system seal set.

Additional dies and options

The source marks a loading table as a recommended option. Separate dies cover embossing, low-mark bending, twisting and cable-lug pressing. Compatibility and working limits are agreed for each die.

Discuss configuration

Send a drawing or photograph of the part, material, thickness, blank size and required output. This lets us compare configurations against your job, not just their power rating.

Tell us what you would like to clarify. Add drawings, photos or the required configuration reference to your request if available.
