Assuming that the punching force required for punching sample is 400kg, the force is related to sample thickness and shear angle, and the existing sampler generally takes 1.5°, so the punching force is not calculated. At this time, the force acting on the guide column and the guide sleeve is 400×Sin1.5=10.5kg, and the required power is 400×Cos1.5=399.9kg.

Figure 1

[0031] A lower cutter 4 with an upward blade and a small cutter block 7 are arranged on the base 1, and an upper cutter 5 with a downward blade 51 is arranged on the movable beam 3, and the upper cutter 5 is matched with the lower cutter 4 and the small cutter block 7.

[0032] As shown in the drawings, the blade 51 of the upper cutter 5 is a left-right symmetrical two-section blade, the slope of the blade 51 of the upper cutter 5 is 1°-60°, the surface of the blade 51 of the upper cutter 5 is concave inward, so as to ensure the sharpness of the blade 51, and the blade 51 is not attached to copper scraps, aluminum scraps and the like, so that more power is saved when punching the sample; and when manually sampling, a sample with a greater thickness can be punched. In addition, the use of a certain slope cutting blade can realize simultaneous shearing of the sample by the left and right blades, so as to avoid the wear of the guide part caused by the left and right side force. Figures 3-4

[0033] In actual arrangement, the upper cutter 5 is two pieces arranged in parallel, and the two upper cutters 5 are matched with the lower cutter 4 to realize sampling, and the sample is in a strip shape.

[0034] As shown in the drawings, the working process is as follows: Figure 2 When the power acts on the movable beam 3, the movable beam 3 drives the upper cutter 5 to descend and punch the sample, the left and right two-section blades 51 of the upper cutter 5 simultaneously contact the sample, and the left and right inclined blades 51 (for example, 3°) of the upper cutter 5 simultaneously shear the sample. According to the shear area calculation formula, when the angle is 3°, the area is about 1 / 2 of that when the angle is 1.5°, and the punching force is 1 / 2 of that when the angle is 1.5°. Assuming that the left and right two-section blades 51 are both 200 kg, then:

[0035] F2=200×Cos3=199.7kg;

[0036]

[0037] ​​​The required power should overcome 2F2=399.5kg, at this time, because the left and right two F1 are the same size but opposite directions, the resultant force of the guide column 2 and the guide sleeve 6 is zero, and the guide column 2 and the guide sleeve 6 will not cause additional force wear.

[0046] The movable beam 3 is perpendicular to the guide column 2, and the guide column 2 is perpendicular to the base 1. This setting effectively ensures the stability of the movement of the movable beam 3 driving the upper knife 5, and improves the balance of the force applied by the upper knife 5, ensures the flatness of the punched sample, and avoids the generation of side force during punching of the sample, thereby avoiding the wear of the guide part caused by left and right side forces.

[0047] In addition, the movable beam 3 is arranged on the guide column 2 through the guide sleeve 6, which improves the stability of the arrangement between the guide column 2 and the movable beam 3, and ensures the stable movement of the movable beam 3, thereby indirectly improving the balance of the force applied by the upper knife 5.

[0048] The guide sleeve 6 is arranged on the guide column 2, and the movable beam 3 is fixedly arranged on the guide sleeve 6.
