Description

Technical Field

[0001] The utility model relates to the field of drop tests, in particular to an adjustable drop test device for plated metals. Background Art

[0002] Due to the different working environments of metals, a layer of other materials needs to be plated on the metal surface to make the metal have the performance to work in this environment. For example, the plating makes the metal have anti-corrosion, wear-resistant or anti-oxidation properties. In order to judge whether the metal coating meets the requirements and avoid the coating from falling off and affecting its normal use, it is necessary to perform a drop test on the plated metal. The drop test is one of the important experimental steps in evaluating the performance and parameters of the experimental samples. The current drop test device can only simulate the falling state of a metal free fall, but cannot simulate the falling state of a metal in a parabola, resulting in incomplete drop test parameters of the plated metal and inability to accurately judge the coating performance of the metal.

[0024] Based on the second embodiment, Figure 1 , Figure 2 and Figure 4 As shown, a horizontal slide groove 22 is provided at the bottom of the experimental board 4, and a bidirectional threaded screw 23 is rotatably arranged in the horizontal slide groove 22.

[0025] Embodiment 4

[0026] Based on the third embodiment, Figures 1 to 3As shown, a guide groove 6 is provided through one side of the horizontal beam 3, and the guide groove 6 extends in the length direction of the horizontal beam 3. A driving slider 7 is slidably provided in the guide groove 6. Both ends of the experimental board 4 are connected to the driving slider 7 through a "7"-shaped rod 8. A guide rod 9 is fixed in the guide groove 6. The driving slider 7 is slidably sleeved on the guide rod 9. A spring 10 is sleeved on the guide rod 9. Both ends of the spring 10 are respectively connected to the driving slider 7 and the horizontal beam 3. A winding shaft 15 is rotatably provided at one end of the horizontal beam 3. A winding reel 11 is fixedly sleeved on the winding shaft 15. The axis of the winding shaft 15 is perpendicular to the axis of the guide rod 9.

When the plated metal simulates parabolic motion in a drop experiment, the motor 14 drives the winding shaft 15 to rotate through the meshing of the driving gear 16 and the driven gear 17, and the winding shaft 15 drives the winding disk 11 to rotate, so that the winding disk 11 reels the pull wire 12, and the pull wire 12 pulls the driving slider 7 to compress the spring 10 to move. When the driving slider 7 moves to the desired position, the cylinder 18 contracts and drives the sliding motor plate 13 to move, so that the driving gear 16 is separated from the driven gear 17, so that the driving slider 7 is immediately released and moves under the reaction force of the spring 10, and then the clamping plate 5 releases the plated metal to simulate the parabolic state. Simulated drop test; the horizontal speed of the driving slider 7 is adjusted by controlling the degree of compression of the spring 10 by the driving slider 7 to simulate the drop test under different parabolic states; it should be noted that when the driving slider 7 is against the end of the guide groove 6, the spring 10 is in a compressed state. At this time, the driving gear 16 and the driven gear 17 can be smoothly engaged, so that after the driving gear 16 and the driven gear 17 are separated, the driving slider 7 can be smoothly moved to contact with the end of the guide groove 6 under the reaction force of the spring 10. At this time, the cylinder 18 extends to drive the motor 14 to reset, so that the driving gear 16 can smoothly engage with the driven gear 17.
