Description
Technical field
The utility model provides a kind of wire rod elongation rate test machine.
Background technology
Wire rod length growth rate is an important mechanical performance index of wire rod, and length growth rate reflects the pliability of wire rod.The method of testing of wire rod length growth rate is get the wire rod of certain length, after being stretched to fracture, measures the length of wires after breaking, and compares with the length before stretching, and calculates length growth rate.
Existing elongation rate test machine is generally to need the wire rod two ends of test to be fixed on fixture, to utilize screw rod transmission to carry out extension test to wire rod.This test machine Problems existing in practical operation has, and can not accurately locate during holder wire rod, and wire rod exists distortion to a certain degree after fixation, and during stretching, easily rupture in termination, causes test crash; In addition, existing testing machine is single-screw mandrel transmission, less stable during work, there are vibrations, and the tensile force fluctuation acted on wire rod causes measuring accuracy inadequate.
Summary of the invention
For solving the problem, the utility model provides a kind of wire rod elongation rate test machine, and comprise frame, scale, driving motor and wheel box, frame left end is provided with fixed support, be provided with two drive lead screws parallel to each other above frame, the left end of drive lead screw is contained on fixed support; Described drive lead screw is provided with rotating nut and slide block, rotating nut is connected with slide block by resilient snubber; Described fixed support and slide block are provided with fixture; Described driving motor and wheel box are arranged on frame right-hand member, and the rotating shaft of driving motor is connected with wheel box, and wheel box is connected with the right-hand member of drive lead screw; Described scale is arranged in frame, and scale and drive lead screw parallel to each other.
Further, resilient snubber is spring or resilient rubbber cushion.
Further, wheel box is infinitely variable transmission, and is provided with synchronizer in wheel box.
Further, the rotation of two drive lead screws is oppositely contrary.
Further, the center line of fixture and drive lead screw parallel to each other.
Further, fixture comprises upper and lower clamp body, and clamp body is provided with the circular locating slot of some different-diameters, and locating slot distributes along fixture length direction.
Useful point of the present utility model is: this programme adopts double lead transmission, good stability, and measuring accuracy improves; In addition, fixture is provided with the locating slot of different-diameter, can be fixed wire rod easily and locate, and improves the success ratio of test.
