Cold Bend Testing Machine QualiBend II
Cold Bend Testing Machine for Steel Reinforcement Bars, Rebars, ASTM A615 – QualiBend Series

The Cold Bend Testing Machine - QualiBend series are used for bending of metallic materials such as metal rods, planks and steel screw threads. The machines operate with a hydraulic loading system to adjust the distance of the cold-bending press roll to drive the rod in both directions making the cold bending press roll forward and back.

Cold Bend Testing Machine for Steel Bar/Steel Plate - ASTM A615 - QualiBend II

ASTM A615/615M, ASTM E290, ISO 7438, API 5L

Application

QualiBend II Series Cold Bend Testing Machine is specially designed to test bend-resistance performance of reinforced rolling steel bars, building steel reinforcements and steel plates which completely meet the requirement of ASTM A615/615M, ASTM E290, ISO 7438, API 5L and other international and national specifications.

Generally, the deformed and plain carbon steel bars for concrete reinforcement in cut lengths shall withstand being bent around a pin without cracking on the outside radius of the bent portion, this machine is capable to be customized for guided-bend (U bend) test on steel plates/welds.

Feature

  • User friendly operation height
  • Interchangeable mandrel (loading nose) and interchangeable roller (cylinder support)
  • Adjustable roller span (distance between cylinder support)
  • User specified loading speed
  • Operations automatically done by software on computer, real time recording the load force and bend deflection
  • Loading nose auto-return available

Software

  • User friendly interface
  • Programmable loading procedure
  • Test data recall, comparison and statistic are available

Test Procedure

  1. Install rollers (cylinder support) and mandrel (loading nose) on machine
  2. Adjust roller span
  3. Place specimen over rollers
  4. Program test procedure on software
  5. Start test on software
  6. Software recording real time load and bend deflection
  7. Mandrel (loading nose) return to original position automatically
  8. Test finish
