Cold Bend Testing Machine

Bend and Re-bend test is a simple and fast qualitative test that can be used to evaluate the ductility and the effect of strain aging on steel. The steel specimen is plastically deformed up to 90° or 180°. After test completion the steel is examined for defects that will increase the risk of steel fracture.

Cold Bend Testing Machine

Used for bending and straightening steel reinforcing bars.

Standards EN ISO 15630-1 EN ISO 7438 EN 10080 ASTM A615

70-C0977
Description

 

Used for bending and straightening steel reinforcing bars. Two types of test can be performed:

  1. Bending the specimen through 90° and then straightening it again up to a minimum of 20°.
  2. Bending through 180°.

The machine consists essentially of a hydraulic jack with cylindrical mandrel-stem, mounted horizontally within a strong steel frame which also carry two fixed reaction rollers. Two 50 and 100 mm dia. rollers are supplied with the machine. Mandrels and mandrel holders have to be ordered separately. Mandrels larger than 96 mm dia. do not need mandrel holders because they fit directly onto the stem.
ASTM specifications require 100 mm dia. rollers only and the bent up to 90°.
