When the protective cover 23 is released, the protective cover 23 will slide downward in the chute 21 to a certain position under the reset action of the spring 22. During the shear test, the metal workpiece can be placed on the fixing frame 7 for fixation. Then start the electric telescopic rod 4 to drive the sliding frame 5 to slide downward on the shear testing machine 1, driving the shear blade 6 to move downward to a certain position to perform shear test processing on the metal workpiece fixed on the fixing frame 7. At this time, the protective cover 23 will descend to a certain position as the sliding frame 5 descends, and the bottom abuts against one side of the shear testing machine 1, completely covering the fixing frame 7, the shear blade 6 and the metal workpiece to be sheared. At the same time, the protective cover 23 will slide correspondingly in the inner wall of the chute 21 according to the depth of the shear, so as not to interfere with the operation of the shear test. At the same time, the metal chips generated during the shear process are not easily sputtered out, avoiding accidental injury to the operator, reducing the potential safety hazard problems existing in the shear test operation, and being convenient for use. Then the data during the shear process will be fed back to the shear testing machine 1 for storage and display.

The elastic clamping block 27 is fixedly arranged obliquely between one side of the limit block 26 and one side of the sliding frame 5. By providing the elastic clamping block 27, after one end of the limit rod 25 is sleeved on one end of the limit block 26, the elastic clamping block 27 will be first squeezed, and then after being clamped to the corresponding position, the elastic clamping block 27 will reset and abut against the top of the limit rod 25, secondarily limiting it on the limit block 26, making the limit on the protective cover 23 more firm. Bearings 28 are fixedly connected to the outer surfaces on both sides of one end of the limit block 26, and the outer rings of the bearings 28 are fixedly connected to the inner wall of the rectangular groove 24. By providing the bearings 28, the rotational wear between one end of the limit rod 25 and the rectangular groove 24 can be reduced, facilitating use.
[0032] Referring to Figures 2-5 As shown in the figure, in this embodiment, a plurality of limit telescopic rods 29 are fixedly connected to the inner wall of the chute 21. One end of the limit telescopic rod 29 is fixedly connected to one side of the protective cover 23, and the outer surface of the limit telescopic rod 29 is sleeved and connected to the inner wall of the spring 22.

[0033] Referring to Figure 6As shown in the figure, this embodiment discloses that the collection device 3 includes a collection box 33. One side of the shear testing machine 1 is fixedly connected with a U-shaped block 31. One side of the inner wall of the protective cover 23 is symmetrically provided with round holes 32. One side of the collection box 33 is fixedly connected with an L-shaped block 34. One end of the L-shaped block 34 is inserted into the inner wall of the U-shaped block 31. The top of the collection box 33 is provided with a collection cover 35. One side of the collection cover 35 is fixedly connected with a fan 36. The outlet of the fan 36 is fixedly connected with a first connecting pipe 37. One end of the first connecting pipe 37 is connected through the side of the collection cover 35. The inlet of the fan 36 is fixedly connected with a second connecting pipe 38. Both ends of the second connecting pipe 38 are respectively inserted into the round holes 32. Both ends of the second connecting pipe 38 are threadedly connected with suction heads 39. Before the shear test, first manually insert one end of the L-shaped block 34 on one side of the collection box 33 into the inner wall of the U-shaped block 31 and hang it on one side of the shear testing machine 1. Then insert both ends of the second connecting pipe 38 into the round holes 32 respectively. Then screw the two suction heads 39 onto the outer surfaces of both ends of the second connecting pipe 38 inserted into the round holes 32 respectively. During shearing, the fan 36 can be started to suck the metal chips covered inside the protective cover 23 from the suction heads 39 into the second connecting pipe 38, and then enter the inside of the collection cover 35 and the collection box 33 through the first connecting pipe 37 for collection, which is convenient for later unified processing and improves the efficiency of the shearing test processing of metal workpieces.

[0035] Working principle: When using the shearing testing machine 1 to perform shearing test processing on metal workpieces, first press the elastic clamping block 27 to move one end of the limiting rod 25 out from the bottom of the elastic clamping block 27. Then manually push the protective cover 23 upward in the inner wall of the sliding groove 21 to a certain position, causing its spring 22 and the limiting telescopic rod 29 to contract, and driving the inner wall of the limiting rod 25 to slide upward on the limiting block 26 for a certain distance. Then rotate one end of the two limiting rods 25 in the rectangular groove 24 by a certain angle, so that the inner wall of the other end moves out from the limiting block 26 to release the fixation of the protective cover 23. When the protective cover 23 is released, the protective cover 23 will slide downward in the sliding groove 21 to a certain position under the reset action of the spring 22. During the shearing test, the metal workpiece can be placed on the fixing frame 7 for fixation. Then start the electric telescopic rod 4 to drive the sliding frame 5 to slide downward on the shearing testing machine 1, driving the shearing knife 6 to move downward to a certain position to perform shearing test processing on the metal workpiece fixed on the fixing frame 7. At this time, the protective cover 23 will descend to a certain position along with the descent of the sliding frame 5, and the bottom abuts against one side of the shearing testing machine 1, completely covering the fixing frame 7, the shearing knife 6, and the metal workpiece to be sheared. At the same time, the protective cover 23 will slide correspondingly in the inner wall of the sliding groove 21 according to the depth of shearing, so as not to interfere with the operation of the shearing test. At the same time, the metal chips generated during shearing are not easily sputtered out, avoiding accidental injury to the operator, reducing the potential safety hazard problems existing in the shearing test operation, and being convenient for use. Then the data during the shearing process will be fed back to the shearing testing machine 1 for storage and display.
[0036] Before the shearing test, first manually insert one end of the L-shaped block 34 on one side of the collection box 33 into the inner wall of the U-shaped block 31 and hang it on one side of the shearing testing machine 1. Then insert the two ends of the second connecting pipe 38 into the round holes 32 respectively. Then screw the two suction heads 39 onto the outer surfaces of the two ends of the second connecting pipe 38 inserted into the round holes 32 respectively. During shearing, the blower 36 can be started to suck the metal chips covered inside the protective cover 23 from the suction heads 39 into the second connecting pipe 38, and then enter the inside of the collection cover 35 and the collection box 33 through the first connecting pipe 37 for collection, which is convenient for later unified processing and improves the efficiency of the shearing test processing of metal workpieces.
