Embodiment 1
[0043] see Figure 1-Figure 8As shown, a metal material detection device based on the comparison of deformation characteristics before and after the extrusion test is provided, including a placement rack 1 and a mounting rack 2 arranged on the upper side of the placement rack 1, and the placement rack 1 and the mounting rack 2 are arranged from bottom to top. There is an extrusion rack 3 for receiving metal blocks, a side detection device 4 for measuring pressure, a extrusion device 5 for extruding metal, and a pressure gauge 6 for measuring pressure. The placing rack 1 includes placing The plate 11 and the limit posts 12 symmetrically fixed on both ends of the placing plate 11. The limit posts 12 are hollow structures. The mounting frame 2 includes two U-shaped insert rods 21, one end of which is slidably inserted into the limit posts 12. , between the upper ends of the two insertion rods 21 near the middle position is fixedly connected with a transverse rod 22, the bottom of...
Embodiment 2
[0054] In order for the device to perform bending tests on metallic materials, refer to Figure 9-Figure 11 One side of the placing plate 11 is fixedly connected with an L-shaped extension rod 16, and the side of the extension rod 16 close to the extrusion frame 3 is hinged with a bending hydraulic rod 17, and the piston rod on the bending hydraulic rod 17 is hinged at the On the side shield 33 on the side wall of the moving plate 32, an arc-shaped arc chute 15 is opened at the end of the placing plate 11 close to the extension rod 16, and the bottom of the moving plate 32 is fixedly connected with the arc-shaped chute 15. The matching arc bar 39 is slidably arranged inside the arc chute 15 .
[0055] When using this embodiment, two pressure sensors 41 are slidably arranged in the positioning plate 31 and the moving plate 32 respectively, and the position of the driving frame 51 is adjusted, so that the driving frame 51 will move the position of the extrusion column 52 above a...
Embodiment 3
[0057] In order to obtain the compression at both ends of the metal material and its central force, refer to Figure 12-Figure 13 , the positioning plate 31 and the moving plate 32 are provided with a bending groove 36, and the ends of the two bending grooves 36 close to each other are inclined upward slopes, and the interior of the bending groove 36 is provided with the bending groove 36. The receiving plate 35 is symmetrically provided with clamping slots 38 at the position of the bending groove 36 close to the slope.
[0058] When using this embodiment, the receiving plate 35 is taken out from the bending groove 36, and the position of the driving frame 51 is adjusted, so that the extruding column 52 in the middle is adjusted to the through chute 513, and the extruding column 52 at the end is set in In the clamping slot 514, the hydraulic rod 23 is pressed down and the piston rod moves down, so that the extrusion column 52 at the end squeezes the end of the metal material. ...
