How does a metric pipe bender work?

Introduction

The use of metric pipe benders is essential in various industries for the precise shaping of pipes. Their inherent accuracy and efficiency make them indispensable. This article provides a comprehensive overview of how metric pipe benders work and highlights the offerings from Hongli Pipe Machinery Company.

Principle of Operation

A metric pipe bender operates on the principle of rotational force applied to a pipe to achieve the desired bend angle. The machine uses a combination of dies to shape pipes with minimal deformation. The standard parameters for bending include:

• Bend Radius: Typically between 2D and 10D, where D is the diameter of the pipe.
• Bend Angle: Ranges from 0° to 180°.
• Material Yield Strength: Benders are designed to accommodate specific materials, with common yield strengths from 205 MPa to 400 MPa.

Components of a Metric Pipe Bender

• Frame: Provides structural support and houses the main components of the machine.
• Dies: Essential for shaping and forming the pipe, available in various sizes for different pipe diameters.
• Clamp: Holds the pipe in place during the bending process to ensure precision.
• Hydraulic System: Delivers the necessary force for bending, particularly for heavy-duty applications.
• Control Panel: Allows operators to input specific bending parameters and operate the machine.

Metric Pipe Bending Process

The process involves several steps to achieve precise bending:

1. Setup: The appropriate die is selected based on the pipe's diameter and the desired bend radius.
2. Calibration: The machine is calibrated using the control panel to set the bend angle and force.
3. Pipe Placement: The pipe is secured in the clamp to prevent movement.
4. Bending: The hydraulic system engages, applying force to bend the pipe around the die.
5. Inspection: The finished product is inspected for accuracy and conformity to specifications.
