Three Cylinder Vertical Hydraulic Bending Testing Machine

Three Cylinder Vertical Hydraulic Bending Testing Machine

Model: UT1014-S3; ISO 7438, ISO 5173, ASTM E290

Hydraulic three-cylinder bending testing machine has a vertical structure, capable of forward and reverse bending, equipped with an LCD touching screen display, with one-time setup and automatic operation. The three-cylinder bending testing machine uses a technology that combines hydraulic loading with a control system.  Conform with ISO 7438, ISO 5173, ISO 10065, ISO 6935-2, ISO 6935-1, ASTM E290.

A vertical cylinder bends the specimen to a certain angle first, and then two opposing horizontal cylinders bend the specimen to the required angle. The bending of the specimen is directly achieved by the downward movement of the main piston, and the 180° bending of the specimen can be realized through the operation of the left and right pistons, making it convenient and efficient to operate. It is mainly used for the process bending of metal materials, capable of controlling processes such as constant-speed loading and constant-speed displacement. It is primarily used to test the ability of metal materials to withstand bending plastic deformation and can perform bending tests on various metal sheets, strips, and steel bars. This testing machine is widely used in industries such as steel metallurgy, quality supervision, construction and building materials, factories and mining enterprises, highway transportation, and bridge and dam construction. It is also an ideal testing device for research institutions and university laboratories.

Standard

ISO 7438 Metallic materials Bending test details

ISO 7438 is a standard that specifies a method for determining the ability of metallic materials to undergo plastic deformation in bending. It is used to evaluate the flexural strength and stiffness of a material , The bend test shall be carried out in testing machines equipped with a bending device with two supports and a former; bending device with a V-block and a former; bending device with a clamp. 

ASTM E290 Metal Bend testing of materials ductility

ASTM E290 Standard Test Methods for Bend Testing of Material for Ductility


ASTM E290  test methods cover bend testing for ductility of materials. Included in the procedures are four conditions of constraint on the bent portion of the specimen; a guided-bend test using a mandrel or plunger of defined dimensions to force the mid-length of the specimen between two supports separated by a defined space; a semi-guided bend test in which the specimen is bent, while in contact with a mandrel, through a specified angle of bend or to a specified inside radius of bend (r) measured while under the bending force; a free-bend test in which the ends of the specimen are brought toward each other, but in which no transverse force is applied to the bend itself and there is no contact of the concave inside surface of the bend with other material; a bend-and-flatten test, in which a transverse force is applied to the bend such that the legs make contact with each other over the length of the specimen.
