LW type metal bending testing machine

The LW type metal bending tester uses hydraulic loading and is manually operated during the test. The test results fully meet the requirements of GB / T232-1999 "Metal material bending test method". It is mainly used for bending mechanical properties test of metal plates, bars, construction rebars and other materials.

 

The LW-50 mainframe adopts a double-column fixed beam structure, the loading cylinder is placed on top, the screw is manually operated to adjust the pitch of the bending rollers, and the hydraulic loading is equipped with a plug-in cold bending fixture. The specimen is bent to the angle required by the test.

 

LW-300 mainframe adopts four-post fixed beam structure. The loading cylinders are distributed vertically and horizontally. The two-way lead screw is rotated by the hand wheel to make the bending rollers move forward / backward synchronously to adjust the cold bending roller distance. Hydraulic two-way cylinder loading, equipped with a plug-in cold bending jig, manual operation of the entire bending test process. In the cold bending test, after the vertical oil cylinder bends the specimen once, the lateral auxiliary cylinder applies a pressing force to make the specimen bend and bend. The unloading angle is equal to 180 °.
