Torsion-bar Synchronized Press Brake

WC67K series · Torsion-bar bending

The torsion-bar synchronized press brake uses a mechanical synchronization arrangement. Selection should distinguish that structure from the controller functions rather than treating it as another name for an electro-hydraulic servo configuration. Review material, bend length and the finished profile before specifying tooling, backgauge and operating arrangements. Springback, trial bends and the agreed part requirements remain part of the assessment, with the exact NC functions and supply scope confirmed for the selected machine.

Mechanical synchronization: Assess bending tasks around the specified torsion-bar mechanical synchronization machine arrangement.
Control confirmation: Confirm NC control and backgauge functions for the particular proposed machine.
Trial-bending review: Review forming requirements against material springback, tooling conditions and representative trials.

Zhongao Torsion-bar Synchronized Press Brake

Confirm synchronization and setup requirements

Torsion-bar synchronization is a machine-structure choice. Select the required force and bend length from the workpiece rather than assuming that all WC67K machines share one specification.

Review the NC system, backgauge, clamping, tooling and front supports with the proposed configuration. Bending results depend on the selected machine, material and setup.

Typical configurations

Torsion-bar synchronized machine arrangement
NC controller and backgauge configuration
Clamping, tooling and front support arrangements

APPLICATIONS

Typical applications

Conventional sheet forming

Review conventional flanges and relatively direct bending routines. Material strength, thickness and bend length need checking together; mechanical synchronization does not remove the need to assess tooling and load.

Repeat-bending work

For repeated parts, confirm the NC arrangement against locating and tool-change steps. Discuss angle and dimensional requirements in relation to material batches, tooling and setup conditions.

Existing workshop tooling

If existing tools and locating practices are to be retained, provide interfaces, dimensions and representative parts. Check clamping compatibility, gauge contact positions and workpiece support arrangements.

SELECTION NOTES

What to check before selection

Structure versus control: Torsion-bar describes mechanical synchronization, not a universal controller, axis layout or result. Define the structure, NC functions, backgauge and tooling scope separately in the quotation.
Tooling and springback: Assess load from material grade, thickness and bend length, with checks on inside radius, V-opening and tool limits. Include springback and angle requirements in trials rather than relying on a structure name.
Process clearance: Check turning, tool interference and machine opening at every bend stage, alongside site power. Discuss supports, clamping and protective arrangements against the actual operating conditions.

Machine photographs illustrate available configurations. Appearance, controller, tooling, protective devices and auxiliary equipment are subject to the agreed supply scope. Final specifications and acceptance requirements are confirmed in the quotation.

PRACTICAL QUESTIONS

Practical selection questions

Clarify the operating conditions and interfaces before deciding on materials, geometry or configuration.

Is torsion-bar synchronization the same as electro-hydraulic servo?

They should not be treated as the same synchronization arrangement. This machine uses mechanical synchronization; controller and backgauge functions still require separate confirmation against the workpiece and acceptance requirements.

Does one series designation imply one specification?

No. Material grade, thickness, working length, tooling and the part profile can all affect selection. The quotation should define the particular configuration and the tasks under review.

How should bend angles be confirmed?

Provide material, inside radius, V-opening and angle requirements for assessment with representative trial parts. Results depend on springback, tooling and setup, not the synchronization arrangement alone.
