Information
Description:
Precise adjustments：

The Crowning System offersprecise macro and micro tuning.
Themacro crown capability adjuststhe beam up to 3.5 mm(depending on length).
Themicro crown adjustmentis available at points every200 mm on the beam forfne-tuning up to 5 mm.

Quick, repeatable crowning power：

Adjustment is fueled by either a manual crank with digital display located at the end of the unit or by an electric motor driven by the CNC machine control.

Secure die holding:

The Crowning System holds dies securely either bymanually tightened set screw severy inch or with quick and simple hydraulic power.

Durable hardened body:

The Crowning system is built to last with a silver body hardened to 28-32 HRC, which makes it substantially tougher than thecompetition.

Advantage:

►Easy reversibility of tools because of symmetrical adaption

►Hand crank with digital readout or CNC electric drive connected direct to the machine

►Hardened to 28–32 HRC which makes it substantially tougher than the competition

►Micro crowning every 200mm

►T & Y adjustable 0–0.76mm (0–0.030")

Description
CROWNING SYSTEMS

1. The Role of Crowning Systems

During the bending process, the worktable and ram of the press brake undergo slight elastic deformation (often referred to as "deflection") under force, which can cause the bending angle of the sheet metal to be inconsistent between the middle and the ends. The role of Crowning Systems is to compensate for this deformation, ensuring uniform bending angles across the entire sheet.

2. How Crowning Systems Work
Crowning Systems typically achieve compensation through the following methods:
Mechanical Crowning: By adjusting the shape or position of the die, it automatically compensates for deflection during operation. For example, using a lower die with a raised crown or installing adjustable shims at the bottom of the die.
Hydraulic Crowning**: A hydraulic system dynamically adjusts the position of the worktable or ram to compensate for deflection in real time.
CNC Crowning**: In CNC press brakes, software controls the movement trajectory of the ram to automatically compensate for deflection.

3. Advantages of Crowning Systems
Improved Bending Accuracy: By compensating for deflection, it ensures uniform bending angles across the sheet, reducing scrap rates.
Extended Die Life: Reduces localized stress concentration caused by deflection, extending the service life of the die.
Strong Adaptability: Suitable for sheets of different thicknesses and materials, meeting diverse production needs.
Increased Production Efficiency: Reduces setup time and rework, improving production efficiency.
