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 frame 1 and a mounting frame 2 arranged on the upper side of the placement frame 1, and the placement frame 1 and the mounting frame 2 are sequentially arranged from bottom to top It is provided with an extrusion frame 3 for receiving metal blocks, a side detection device 4 for measuring pressure, an extrusion device 5 for extruding metal, and a pressure gauge 6 for measuring pressure. The placement frame 1 includes a placement The plate 11 and the limiting columns 12 symmetrically fixed on both ends of the placing plate 11 are left and right. The limiting columns 12 are hollow structures, and the mounting frame 2 includes two U-shaped inserting rods 21, one end of which is slidably inserted into the limiting column 12. The position between the upper ends of the two insertion rods ...
Embodiment 2
[0054] In order for the device to perform bend tests on metallic materials, refer to Figure 9-Figure 11 One side of the placement plate 11 is fixedly connected with an L-shaped extension rod 16, and the side of the extension rod 16 close to the extruding frame 3 is hinged with a bending hydraulic rod 17, and the piston rod on the bending hydraulic rod 17 is hinged on the On the side guard plate 33 on the side wall of the moving plate 32, the end of the placing plate 11 close to the extension rod 16 is provided with an arc-shaped chute 15, and the bottom of the moving plate 32 is fixedly connected with an arc-shaped chute 15. The arc bar 39 that matches, the arc bar 39 is slidably arranged in the inside of the arc chute 15.
[0055] When the present embodiment is in use, two pressure sensors 41 are respectively slidably arranged in the positioning plate 31 and the moving plate 32, and the position of the driving frame 51 is adjusted so that the driving frame 51 will position t...
Embodiment 3
[0057] In order to obtain the pressure on both ends of the metal material and the force on the middle, refer to Figure 12-Figure 13 , the positioning plate 31 and the moving plate 32 are provided with bending grooves 36, and the ends of the two bending grooves 36 close to each other are inclined upward slopes. The receiving plate 35, the bending groove 36 is provided with a draw-in groove 38 symmetrically near the position of the slope, and one end of the receiving plate 35 is fixedly connected with a draw bar 37 inserted in the draw-in groove 38 inside symmetrically.
[0058] When this embodiment is in use, the receiving plate 35 is taken out from the bending slot 36, and the position of the drive frame 51 is adjusted so that the extrusion column 52 in the middle is adjusted to the through chute 513, and the extrusion column 52 at the end is arranged on the In the locking groove 514, press down the hydraulic rod 23 and the piston rod moves down, so that the extrusion column ...
