Cold Bend Testing Machine Type SBM Cold Bend Testing Machine Type BTM-H350 Steel Bending and Folding Machine Series BDM 2000 kN
Cold Bend Testing Machine Type SBM
Designed for bending and straightening (re-bend)
This rebar bend and re-bend unit is designed to verify the bend resistance of reinforcing steel bars in accordance with EN 15603-1,
ISO 7438, ASTM A615&A615M, EN 10080, BS4449 and other international standards.
The test consists in bending the bar up to 180° or to bend the same at 90° and then straighten (re-bend) if of at least 20°. The horizontal design makes specimen loading and machine operation easy. The machine is easy to operate. Beside of the main switch the hydraulic pump can be started and stopped by pressing the relevant bottoms. The manual operated valve allows to move the cylinder forward or backward by simple stir the handle in direction the cylinder shall move. The piston speed can be adjusted at the throttle valve. The hydraulic power supply with its components is integrated in the machine base. The base also offers storage space for the different mandrels, brackets and working tools. The safety guard that covers the work-space protects the operator in accordance with the 89/392/CEE Directive. The Protection device is supported by gas springs that make the opening and closing easier. The transparent top of the protection device enables the operator to have a good view to the unit during the test. The protection device is electrically monitored. The mandrels with different diameters are easy to change and the support rollers easy and stepless adjustable in accordance with relevant standard. This unit is suitable for specimen diameters between 5 and 40 mm.

The piston rod have some guidance to prevent horizontal/vertical buckling.
This unit is suitable for specimen diameters up to 63 mm.
The mandrels and the mandrel-holders are not included in the standard supply and have to be ordered separately.
High Capacity Steel Bending and Folding Machine Series BDM up to 2000 kN
w+b offers testing machines for Bending Tests according to different standards including ISO 7438, ASTM A615, DIN 50121 and others.
We have developed the BDM series for Bending, Reverse Bending and Folding of Flat Steel Sheets, Plates and Fracture Toughness Bend Specimens (SEB) for fracture analysis.
This test system provides high force combined with operator convenience. Main parts are a vertical servohydraulic long stroke actuator equipped with force measurement system, two horizontal actuators to move and adjust the distance of the lower bend supports, integrated camera system to observe sample cracks, sample handling system and flexible digital control system with application software. Mandrels of different radiuses can be easily and conveniently installed as well as lower support rollers can be exchanged. The support distance is automatically adjusted according to pre-defined templates for selected sample. The coaxial integrated camera records the bend sample surface and allows the operator to stop the test once visual cracks in the sample occurs. As the system allows testing of large and heavy specimens there is an integrated manual sample handling / loading system that enables the introduction of such bulky specimens easily into the testing machine.
