When the clamp 3 is fixed on the sample carrying plate 2, as shown in fig. 1, the clamp 3 is horizontally placed, all the sample steel belts 6 are vertically placed, the first side edge is positioned below the second side edge and is closer to the polishing mechanism 5, then the polishing mechanism 5 is lifted and pressed on the first side edge, then the driving device 4 drives the sample carrying plate 2 to reciprocate back and forth, the clamp 3 and the sample steel belts 6 on the clamp 3 also reciprocate back and forth under the driving of the sample carrying plate 2, so that all the sample steel belts 6 move back and forth relative to the polishing mechanism 5, synchronous polishing of the first side edges of all the sample steel belts 6 is automatically completed, burrs on the first side edges are removed, the polishing efficiency is high, and the labor intensity of workers is greatly reduced.

After the first side edge is polished, the polishing mechanism descends, the clamp 3 is turned, all the sample steel belts 6 are vertically placed, the second side edge is located below the first side edge and is closer to the polishing mechanism 5, then the polishing mechanism 5 ascends to abut against the second side edge, and the second side plate is polished in the polishing mode; after the final test sample steel belt 6 is polished, the width of the stretching section is 11.5-12.5 mm, the edges of two sides of the test sample steel belt 6 are smooth, burrs and small cracks are eliminated, the test sample steel belt 6 forms a standard test sample, and the accuracy of the result of a mechanical tensile test is ensured.
