Bending fixture for hydraulic universal testing machine
1.Application:
The machine adopts hydraulic loading, Computer Display, easy and convenient to operate. It is mainly used to execute the tension, compression, bending, flexural etc. test for metal materials. Attached with simple accessories and devices, it can be used to test wood, concrete, cement, rubber, and so on.It is very suitable for making test to different metal or nonmetal materials under high toughness and hardness against extreme big loading force.
2.Standards:
ISO6892, BS4449,ASTM C39,ISO75001, ASTM A370, ASTM E4, ASTM E8 and BSEN standards.
3.Frame:
The oil cylinder is at the bottom of the load frame,tension space is at the upside and compression &bending spaces are between lower crosshead and working table.It is adopting oil hydraulic power to push the piston in the oil cylinder to provide loading force.The lower crosshead is driven by motor throng decelerator,chain transmission device and screw pair to realize the adjustment of testing space.
