Bend Test Equipment Manufacturer,Supplier and Exporter in India

Product Code : EL-SWES-8749
Jlab Export is a leading Bend Test Equipment Manufacturer,and suppliers in India

This bend tester folds steel rod and plate specimens through 180° under a hydraulic load of up to 200 kN. It bends the specimen in one stroke, then side loads finish the bend to the full 180°. One operator runs each test from push buttons, and the specimen bends down into a closed test table. A dust shield keeps oxide scale off the ball screw.

Bend Test Practicals for Welding Students

A bend test shows whether a metal, or a welded joint, can stretch round the outside of a bend without cracking. Students start with plain steel rod. They measure each rod with a Dial Caliper, choose the former for that diameter, bend the rod and look for cracks on the outer face.

For weld testing, two plates are butt welded on the Shielded Metal Arc Welding Machine. Strips 50 mm wide are cut across the joint on the Power Hacksaw Machine, and the weld cap is ground flush with an Angle Grinder. Once bent, any lack of fusion or porosity in the weld opens up as a crack the class can see.

Frequently Asked Questions

What sizes of specimen does the machine take?
Round rod from 6 to 40 mm in diameter, and plate from 6 to 25 mm thick with a width of 50 mm. Every specimen can be taken round to a maximum bend of 180°.

How is the bend diameter chosen?
The test specification for the material sets the former size, usually as a multiple of the bar diameter or plate thickness. The machine has 55 former sizes from 2.75 to 192 mm, and other diameters can be made to order.

What counts as a pass in a bend test?
After bending, the outer, stretched face is checked for cracks, tears or open defects. The specification being followed sets how large a defect may be before the specimen fails. A clean outer face with nothing opened up is the usual sign of a sound weld or a ductile bar.

What power supply and floor space does it need?
It draws 2.2 kW from a 380 V AC, 50 Hz supply. The frame measures 890 x 860 x 1970 mm and weighs about 1000 kg. Plan a level floor that can carry it, with room around it to load specimens.

How many people are needed to run a test?
One. The operator places the specimen and works the machine from push buttons. The two-way hydraulic cylinder moves quickly when loading, unloading and withdrawing, and a waste cart collects scale and broken pieces.
