Bend Rebend Machine As per IS standard.

The Bend and Re-bend Test Machine is used to test the ductility and re-bending capacity of steel bars (commonly TMT bars) as per Indian Standards. Here's a detailed explanation of its meaning and relevance

A Bend and Re-bend Test Machine is a laboratory equipment used to: Bend a metal bar (usually reinforcement steel) to a specified angle (generally 180°), Hold it in that position, Then re-bend it after a specific duration and temperature to check for cracks or surface flaws.

Features of Bend Rebend Machine As per IS standard

Bend and Rebend Test Machine is used for testing the ductility and bending strength of steel bars, typically used in construction (like TMT bars). The test is conducted as per the IS 1599 and IS 1786 standards. Below are the features of the Bend and Rebend Machine as per IS standards:

• Rigid Construction: Made of heavy-duty steel frame for stability during operation.

• Bending Angle Range: Should be capable of bending steel rods up to 180 degrees or as per test requirements.

• Rebend Capability: Should allow heating of the bent sample to 100°C and rebending at a specified angle (commonly 135° or 157.5°) as per IS 1786.

• Rebend Capability: Should allow heating of the bent sample to 100°C and rebending at a specified angle (commonly 135° or 157.5°) as per IS 1786.

• Bar Diameter Range: Must accommodate test specimens ranging from 6 mm to 40 mm diameter bars (TMT steel rods or bars)..

• Mandrel and Supports: Comes with interchangeable mandrels of different diameters as specified in IS 1599. Support rollers should be spaced correctly based on bar diameter.

• Speed Control: Should have variable speed settings for smooth operation and controlled bending.

• Manual or Motorized Operation: Available in both manual and electrically operated models. Electrically operated ones typically use gear motors.

• Heating Arrangement (for Re-bend Test): Provision for heating the bent portion of the bar in a hot air oven or heating system to the required temperature (100°C ±10°C).

• Angle Indicator: Built-in angle protractor or digital angle display to monitor the bend angle precisely.

• Safety Features: Emergency stop button. Enclosed gears and moving parts to prevent accidents.

• Compliance: Should comply with IS 1599:1996 – Method for bend test. Also must meet IS 1786:2008 – For High Strength Deformed Steel Bars and Wires for Concrete Reinforcement.

Purpose of Test

To assess ductility, brittleness, and quality of steel, Especially for TMT bars, which are used in construction and must endure bending and straightening during installation.

Working Process

• Bend Test: Bar is bent to a specified angle (e.g., 180°) using the machine. No visible cracks should appear.

• Re-bend Test: The bent bar is heated to 100°C ± 10°C for a specified time. Then, it is bent back to a reduced angle (e.g., 157.5° or 135° depending on spec). Again, it is checked for any cracks or failure.

Uses of Bend and Rebend Machine as per IS Standards.

• Ductility Testing of Rebars (IS 1786): The machine checks if rebar can withstand a specified bend without cracking, which indicates ductility and good metallurgical properties.

• Rebend Test for Aging Resistance (IS 1599, IS 1786): After initial bending, the bar is aged (heated to 100°C for 30 mins) and then re-bent to check resistance to cracking—this simulates site conditions and long-term performance.

• Ensuring Structural Safety: It verifies that rebars will not fail under stress due to improper bending during handling and placement in construction.

• Conformance to Indian Standards: Helps manufacturers and testing labs to ensure their reinforcement bars meet the mechanical requirements laid out in IS 1786 and IS 1599.

• Quality Control in Steel Plants: Regularly used in in-house laboratories to test production batches before dispatch.

• Third-Party Certification & Compliance Testing: Used by external inspection agencies for verifying product compliance for government or critical infrastructure projects.

• Research & Development: Useful in developing new alloys or bar designs to analyze bending performance under different formulations or heat treatments.
