Abstract
The invention relates to a strip-type tube test piece drawing device. The strip-type tube test piece drawing device comprises a main machine, an upper clamp, a lower clamp and a movable cross beam, wherein the upper clamp comprises a first fixing plate and a first clamping plate, the first fixing plate is fixedly arranged at the center position right above the main machine, a first through hole is formed at the center of the first clamping plate, a first groove is formed on the upper surface of the first clamping plate, the lower clamp comprises a second fixing plate and a second clamping plate, a second through hole is formed at the center of the second clamping plate, the second through hole corresponds to the first through hole, a second groove is formed on the upper surface of the second clamping plate, the second groove corresponds to the first groove, a threaded rod is fixedly connected on the lower surface of the second fixing plate, the threaded rod is in transmission connection at the center of the movable cross beam, a nut is arranged on the threaded rod, and the nut is positioned under the movable cross beam. The strip-type tube test piece drawing device has simple structure, can be operated conveniently, and can effectively overcome the defect that the measurement result is influenced due to deformation of the strip-type test piece, the labor cost is reduced and the working efficiency is improved.
Description
Technical field
The present invention relates to tubing manufacturing technology field, especially relate to a kind of tubing band sample stretching device.
Background technology
In production, the test of the tensile property of tubing, normally tubing is cut a bit of clamping to complete on stretching testing machine, instead of homogeneous tube is measured, like this, the band sample intercepted from tubing is circular arc, and the most traditional clamping method is by direct for band sample clamping, band sample can be made to be out of shape, to affect test accuracy.Traditional clamping method makes a call to two holes respectively at two of bar shaped test specimen, then screw or pin etc. are penetrated circular hole, then gib screw or pin are tested on tension tester, the shortcoming of this method is: band sample always occurs bending and deformation and affects test result, and because through hole is too thin to the wall thickness of termination, in the process of experiment, through hole easily destroys, and causes test to stop.
Summary of the invention
The technical problem to be solved in the present invention is: can change the shape of batten to overcome fixture common in prior art thus affect the problem of measurement result, providing a kind of tubing band sample stretching device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of tubing band sample stretching device, comprise main frame, upper fixture, lower clamp and moving beam, described upper fixture comprises the first fixed head and the first clamping plate, described first fixed head is fixedly mounted on above main frame, described first clamping plate center has the first through hole passed through for band sample, the upper surface of described first clamping plate has the first groove coincide with band sample nose shape, the center of described first groove is identical with the center of described first through hole, described lower clamp comprises the second fixed head and the second clamping plate, described second clamping plate center has the second through hole passed through for band sample, described second through hole is relative with the position of the first through hole, the upper surface of described second clamping plate has the second groove coincide with band sample nose shape, the center of described second groove is identical with the center of described second through hole, described second groove is relative with the position of the first groove, described second fixed head lower surface is fixedly connected with threaded rod, described threaded rod is in transmission connection at the center of moving beam, described threaded rod is provided with nut, described nut is positioned at the below of moving beam.
Band sample is inserted respectively the first through hole and the second through hole, then rotate band sample, after snapping in the first groove and the second groove to band sample, host work.
The invention has the beneficial effects as follows, structure of the present invention is simple, easy to operate, effectively solves plain clamp and causes band sample to be out of shape the drawback of vivid measurement result, reduces labour cost, increases work efficiency.
