Abstract

The invention discloses a cylindrical metal compressive strength testing device which comprises a machine base, a driving extrusion part, two oppositely-arranged supporting plates and chucks arranged on the two sides of the two supporting plates respectively, limiting blocks are installed on the chucks, grooves are formed in the limiting blocks, and the driving extrusion part is connected with the chucks. According to the scheme, the limiting block is arranged on the chuck, and the groove with the diameter the same as that of the cylindrical workpiece is formed in the limiting block, so that the cylindrical workpiece can be limited to slide due to shearing force in the pressurizing process, the cylindrical workpiece is always kept at the centering position, and the detection accuracy can be improved. The cylindrical metal compressive strength testing device has the advantage of high detection accuracy.

Description

technical field [0001] The invention relates to the field of metal material performance testing devices, in particular to a cylindrical metal compressive strength testing device. Background technique [0002] In the prior art, when performing the extrusion strength test on a cylindrical metal workpiece, the method of extrusion at both ends is usually adopted. In this way, in the process of gradually increasing the pressing force of the driving part, a large shearing force will be generated between the bottom surface and the top surface of the cylindrical metal part and the clamping part, which will cause the workpiece to slide out of alignment and cause toilet cleaning. The result is inaccurate. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a cylindrical metal compressive strength testing device, which aims to provide a testing device that can accurately measure the compressive strength of cylindrical metal workpieces. [0004]...
