Abstract
The invention relates to a tensile strain frictional wear testing method and a testing machine thereof, particularly including: under the condition of different deformations implemented on a test pieces, performing the frictional wear test on the test pieces, measuring the data under the corresponding deformation state, to characterize the friction and wear resistance of the test pieces. The testing method and the testing machine thereof realize the frictional wear testing under the prestress, match with the loading condition superposition in the practical stamping procedure, obtain the wear resistance of the test pieces under different deformation conditions, meanwhile the forms that the test pieces are hung on the mounting post are adopt, which prevents the easy linting in the primary fixing, further advances the test accuracy.
Description
Technical field
The present invention relates to a kind of rubbing wear detection range, especially a kind of stretching strain frictional wear test method and testing machine thereof.
Background technology
Coating sheet material is in deformation processes such as impact briquetting, the sheet material matrix is to the coating transmitted load on the one hand, cause coating in stretching or compression process, to be damaged, can transmit contact load when the punching press grinding tool directly contacts with coating on the other hand, cause coating scratching and wearing and tearing.In the prior art, generally be under static no-load situation, check the efflorescence degree of coating, to estimate the quality of coating by the mode of rubbing wear.But find after deliberation, under different working conditions, the destruction situation difference of coating is especially under the combined action of various working, the destruction situation of coating is complicated more, and the result of the frictional wear experiment that carries out under the situation of no plus load can not reflect actual conditions
Summary of the invention
The problem that exists at prior art, but the object of the present invention is to provide a kind of stretching strain frictional wear test method and testing machine thereof of coating quality of thoroughly evaluating impact briquetting process floating coat sheet material.
For achieving the above object, stretching strain frictional wear test method of the present invention is specially: test specimen being implemented under the situation of different distortion test specimen is carried out friction-wear test, record the data under the corresponding deformation state, to characterize friction resistant, the polishing machine of test specimen.
A kind of stretching strain frictional wear testing machine of implementing said method comprises testing machine body and test specimen erecting bed, the test specimen erecting bed is fixedly mounted on the worktable of testing machine body, the test specimen erecting bed comprises base plate and a pair of back up pad, wherein a back up pad is fixedly installed on the base plate, another piece back up pad is movably arranged on the base plate, be respectively arranged with at least one card post on the every back up pad, on the back up pad of activity setting, also be connected with a drive unit; The middle part of described base plate is provided with a test specimen supporting plane.
Further, described base plate is provided with mounting hole.
Further, described drive unit is a leading screw, and this leading screw can pass through step motor drive.
Stretching strain frictional wear test method of the present invention and testing machine thereof, realized the friction-wear test under prestress, load-up condition stack in its realistic punching course, drawn the wear resistance of test specimen under different deformation conditions, adopt test specimen to be mounted on form on the erecting bed simultaneously, prevent from when original clamping, to cause easily the phenomenon of bare terminal end coating shedding, further improved the accuracy of measuring the degree of wear in the test by the loss in weight.
