Large Tonnage Press Brake

PREF Group provides CNC and hydraulic press brake machine for high-precision sheet metal bending, our machines range from 30T to 12000T capacity and are widely used in steel fabrication and industrial manufacturing.

Press Brake Machine

Large Tonnage Press Brake

Large tonnage press brake is designed for thick plate, long parts, structural fabrication, and applications where a standard press brake does not provide enough force or working length. The buying decision must include machine capacity, foundation, handling, tooling, safety, and transport.

Main Features

  • Suitable for steel structure parts, heavy machinery components, long plates.
  • Key configuration checks include tonnage calculation, bending length, frame deflection control.
  • Available selection focus: single large-tonnage press brake and custom heavy-duty press brake.
  • Final model, voltage, controller, safety system, and options can be confirmed by PREF Group according to the buyer drawings.

Detailed Description

Configuration Details

Configuration 01

CNC Controller

The CNC controller is used to manage heavy-duty bending programs, Y1/Y2 synchronization, backgauge positioning, crowning data, tooling parameters, and correction values for large plate work. On a large tonnage press brake machine, the control system must support stable ram movement under high load and maintain consistent bending logic for long workpieces. For thick plate fabrication, repeat orders, and multi-step bending, the controller helps reduce manual calculation, improve setup accuracy, and keep the bending sequence easier to manage across different operators.

Configuration 02

Main Motor

The main motor must provide enough power reserve for high-pressure bending, long bending lengths, and continuous heavy plate production. Large tonnage press brakes are often used for steel structures, shipbuilding parts, mining equipment, trailer beams, crane components, and other large fabricated workpieces, so the motor configuration directly affects pressure response and production rhythm. A properly matched motor helps the machine build pressure smoothly, return reliably, and maintain stable output during demanding production cycles.

Configuration 03

Backgauge System

The backgauge system is designed for positioning large and heavy plates before bending. Compared with standard press brake applications, large tonnage machines require stronger backgauge structure, longer travel range, stable guide support, and reliable positioning under heavy workpiece handling conditions. A rigid backgauge with servo drive, ball screw transmission, and linear guide rails helps control flange dimensions, reduce repeated measurement, and improve batch consistency when processing long parts or deep-flange components.

Configuration 04

Electrical Parts

The electrical system must be configured for high-power machine operation, stable signal transmission, and safe control of heavy-duty bending functions. Large tonnage press brakes usually require careful matching of voltage, phase, frequency, motor power, safety protection, control cabinet layout, and workshop installation conditions. A well-organized electrical system improves anti-interference performance, makes inspection easier, and supports safer maintenance for machines used in large fabrication plants and high-load production environments.

Configuration 05

Crowning Compensation

Crowning compensation is especially important on large tonnage press brakes because long worktables and heavy bending loads can create visible deflection during operation. Without suitable compensation, the bending angle may differ between the center and both ends of the workpiece. A properly selected crowning system helps correct ram and table deformation, improve straightness, and maintain more consistent angles across the full bending length. This is critical for thick plate, long part, and high-accuracy structural fabrication.

Configuration 06

Press Brake Punches and Dies

Tooling for large tonnage bending must be selected according to bending force, material thickness, plate grade, V-opening, bending radius, and required part geometry. Heavy-duty punches and dies need sufficient load capacity and stable contact surfaces to handle thick plates and long bending lines. Correct tooling selection helps reduce tooling wear, avoid excessive marking, protect the machine from overload, and improve angle stability. For large fabricated parts, tooling length, segmentation, and die opening should be confirmed together with the actual drawings.

Configuration 07

Ball Screw and Linear Guide

Ball screws and linear guides are used to keep the backgauge movement smooth, accurate, and repeatable during long-term production. On large tonnage machines, positioning components must resist vibration, dust, and heavier operating conditions while maintaining accurate movement. Reliable transmission and guide components help reduce backlash, improve response, and keep flange positioning consistent. This is especially useful when the machine processes large-format plates that are difficult to reposition manually after each bending step.

Configuration 08

Servo Motor

Servo motors provide accurate motion control for backgauge axes and other positioning functions according to the selected machine configuration. For large tonnage press brake applications, servo control helps improve positioning repeatability, reduce manual adjustment, and support stable production of heavy parts with repeated dimensions. Smooth acceleration, controlled deceleration, and accurate stopping are important when the backgauge carries larger structures or works with long plates where small positioning errors can lead to visible part deviation.
