Technical details and manufacturing context for Bending Die Holder

Definition

The Bending Die Holder is a critical component of the Bending Arm Assembly that provides rigid, accurate mounting and alignment for bending dies. It ensures proper die positioning during metal forming operations, maintaining dimensional accuracy and repeatability in bending processes. The holder is designed to accommodate standard bending dies with a die height range of 50–200 mm and a die width range of 20–100 mm. It offers a clamping force of 20–50 kN to securely hold the die in place, and achieves positioning accuracy of ±0.05 mm and repeatability of ±0.02 mm, which are critical for consistent bending results. The holder operates within a temperature range of -10 to 60 °C and is rated IP54 for protection against dust and water splashes. It is manufactured from tool steel or alloy steel, with a typical material grade of 42CrMo4 (DIN EN 10083) and a surface hardness of 48–52 HRC (DIN EN ISO 6508). The weight of the holder ranges from 15 to 30 kg, depending on size. The maximum operating pressure is 16 MPa, which should not be exceeded. This component is used in fabricated metal product manufacturing, specifically in bending operations where precise die alignment is essential. The holder uses mechanical clamping mechanisms, such as bolts, wedges, or hydraulic systems, to secure the die and transfer bending forces from the bending arm to the die while maintaining alignment. It is important to verify model-specific values and standards with the legal manufacturer or supplier before procurement or use.

Working Principle

The Bending Die Holder uses mechanical clamping mechanisms, such as bolts, wedges, or hydraulic systems, to secure bending dies in place. It transfers bending forces from the bending arm to the die while maintaining precise alignment, allowing for consistent bending angles and preventing die movement during operation. The clamping force of 20–50 kN ensures secure holding, and the positioning accuracy of ±0.05 mm and repeatability of ±0.02 mm contribute to consistent results. The holder is designed to accommodate dies within specified height and width ranges, and its operating temperature range and IP rating define its environmental limits. Proper installation and maintenance are necessary to maintain performance.
