　　T-type bending machine technical parameters:

　　■One-time bending angle∠45°

　　T型弯折机操作步骤：

　　■旋转弯曲杆上的螺丝，压力辊便作用于测试片上，圆轴则在下方，转动弯曲杆，直到其达到仪器右手边的**限位。此运动将引起测试片围绕选定圆轴弯曲。

　　■弯曲过程需在一个平稳的运动中进行，时间为1~2秒。

　　■弯曲机构的杆转到左手边的**限处（与黑色旋钮相对）。此动作松开圆柱的贮槽。将所需的圆柱放到槽中，将测试片垂直插入到圆柱和压力辊轴之间（涂层面对着弯曲柱），并推入下端的夹紧装置之间。夹紧单元可以调节，但在此时期，夹装置不应完全锁紧。拉动黑色的旋钮，通过导向辊，和夹紧单元一起滑动插入的测试片，使它的位置对着圆轴。然后完全锁紧黑色的旋钮，确保夹紧单元和测试板固定在此位置。

　　T-bending machine operation steps:

　　■Rotate the screw on the bending rod,the pressure roller acts on the test piece,and the round shaft is below.Turn the bending rod until it reaches the**limit on the right hand side of the instrument.This movement will cause the test piece to bend around the selected circular axis.

　　■The bending process needs to be performed in a stable movement,the time is 1~2 seconds.

　　■The lever of the bending mechanism is turned to the**limit on the left hand side(as opposed to the black knob).This action releases the cylindrical tank.Place the required cylinder into the groove,insert the test piece vertically between the cylinder and the pressure roller shaft(the coating faces the curved column),and push it between the clamping devices at the lower end.The clamping unit can be adjusted,but the clamping device should not be fully locked during this period.Pull the black knob and slide the inserted test piece with the clamping unit through the guide roller so that its position is facing the round shaft.Then fully tighten the black knob to ensure that the clamping unit and test board are fixed in this position.
