Computer Controlled Electro-hydraulic Servo Bending Testing Machine

  • SBT series computer control electro-hydraulic servo bending testing machines are mainly used for bending and pressing tests for metallic sheet & round bars as per standards of ASTM E290, ASTM A615/A615M, ISO 7438, ISO 8491, GB/T232 and YB/T 5126 Metallic Materials Bending Test.


  • • Load frame: door type structure with four columns.

    • Control mode: computer servo control or manual control.

    • Bending & pressing can be performed at the same time.

    • Vertical oil piston with stroke limit function helps for batch test.

    • Main piston is installed on the upper crosshead, while lateral pistons are located at both side to realize balancing pressing.

    • With electro-hydraulic servo system, constant test load, constant test load speed ratio, and constant speed close-loop; auto return to the initial position, bending angle auto control can also be realized.

    • Safety actions: over load protection, over stroke protection, over temperature & auto-warning etc.

Model: SBT Series
Description:
SBT series computerized bending testing machines are mainly used for bending and pressing tests for metallic sheet & round bars as per standards of GB/T232-2010 & ISO 7438-2005 Metallic Materials-Bend Test. An axial oil cylinder for bending test is installed on the top cross-head. Two pressing oil cylinders are installed at both sides of the frame, which adopts the synchronous control, to realize the pushing and pressing force on the bending support to adjust the distance between pivots. The pressure meter indicates the pressure in bending or pressing. Various load display can be selected, such as display through the pressure meter, digital display, and computer screen display etc. The computer control type SBT bending testing machine can do the bending test automatically or manually. The applied bending force can be adjusted by controlling the oil feed valve.
