Finite element analysis diagram

-The press brake's mechanical structure and all major components undergo 3D analysis and optimization design, guaranteeing an attractive design and reliable structure for stable machine operation.

Rigid Frame Design

-The machine is designed and built with a welded one-piece frame that is machined without repositioning to guarantee sturdiness and precision.

Integrative Processing

-The entire machine frame is finished in an integral process using a CNC three-dimensional machining center to ensure high accuracy.

Double guide rail structure

The original main rail is enhanced with a pair of auxiliary guide rails, incorporating copper alloy wear-resistant plates and embedded graphite particles to ensure smoother guiding performance.

How do the YI and Y2 axes work?

With the adoption of fully closed-loop electro-hydraulic servo control technology, the position signal of the slider is fed back to the controller by linear encoders on both sides. Subsequently, the CNC controller regulates the oil volume of the oil cylinder by modulating the opening size of the proportional valve core, ensuring the slider (Y1, Y2) operates on a consistent plane. It maintains a parallel state with the worktable.

Linear Encoder

A high-precision linear encoder is adopted as a displacement sensor, which is installed on the C-shaped plate to detect the oil cylinder's position accurately. The feedback accuracy is up to 0.01mm, enabling precise bending angle control.

Hydraulic System

The hydraulic system utilizes an imported integrated control system, minimizing pipeline installation and eliminating oil leakage while enhancing the stability of the machine tool, and boasting an aesthetically pleasing, simple appearance. The integration with linear encoders establishes a precise control system, which ensures rapid response, accurate flow control, minimal heat generation, and exceptional durability.

Outstanding electro-hydraulic cylinder

- Our high-quality oil cylinder is designed to enhance the performance of your press brake while eliminating oil leakage.
- Constructed with top-grade materials and advanced technology, this oil cylinder ensures reliable and long-lasting performance.
- Its sturdy construction and precision engineering make it a reliable component that contributes to the overall stability of the press brake.

Motorized CNC-controlled anti-deflection worktable

-The CNC crowning device can be automatically adjusted according to the instructions programmed into the CNC system, making it highly convenient and efficient.

Without Crowning

Without crowning for the plate, there may be concave or convex deformations in the plate.

Proper Crowning

With proper crowning for the plate, it is easy to produce a plate that meets the requirements.

Benefiting from the single servo pump control technology, the oil is supplied only when needed, providing quieter, more energy-saving and more environ mentally friendly operation, making it the best choice for consumers who focus on sustainable development and growth.

-All upper punches and lower dies are inductively hardened

-Our engineers will recommend the most suitable tooling based on your part drawings, common sheet metal thickness, opening height, and bending force of the pressure brake.
