Abstract
The invention discloses a small stretch bending device, which is composed of a bending loading mechanism, a test piece clamping mechanism, a stretch loading mechanism and a bending displacement measuring apparatus. The stretch loading mechanism drives first stage worm and gear through a motor, then a bidirectional lead screw-nut pair converts curve motion into linear motion, a tensile force is loaded to two ends of a test piece clamp, and then the tensile force is loaded to the test piece. One end of the clamp is equipped with a tension-compression sensor for detecting the tensile force borne by the test piece. The stretch displacement can be monitored at any time through a contact type displacement sensor installed below the clamp. The bending loading mechanism drives a worm and gear through a motor, and then a unidirectional lead screw-nut pair converts curve motion into linear motion so as to drive a base mounted on the lead screw and a bending pressure head to realize reciprocating motion. The bending displacement can be detected by the contact type displacement sensor installed on the base. The bending pressure head is also equipped with a miniature tension-compression sensor for detecting the stress of the pressure head during bending.
