[0024] like Figure 1 , Figure 2As shown, a steel strength testing device comprises a testing table 1, a conveyor belt 2 is arranged below the testing table 1, a steel plate picking mechanism 3 is arranged on the top of the testing table 1, a fixed box 4 is arranged in the middle of the testing table 1, a sliding control component 5 for controlling the front-rear movement of the fixed box 4 is arranged on the surface of the testing table 1, a defective unloading component 7 is arranged on the surface of the fixed box 4, a testing component 6 is also arranged on the top surface of the testing table 1, and a defective box 8 is arranged on the front side of the testing table 1. More specifically, the steel plate is transported by the conveyor belt 2. When the steel plate moves to the bottom of the testing table 1, the fixed box 4 is controlled to move forward by the sliding control component 5, so that the testing table 1 can be easily transported. The middle part of the test bench 1 is exposed, and the steel plate is grabbed and lifted by the steel plate picking mechanism 3, and then the fixed box 4 is controlled to reset by the sliding control component 5, and the steel plate is placed on the surface of the defective unloading component 7 in cooperation with the steel plate picking mechanism 3, and the steel plate is subjected to an extrusion test by the testing component 6. The strength of the steel plate can be evaluated by observing the deformation of the steel plate. If the steel plate is unqualified, the steel plate is transported to the interior of the defective box 8 for storage by the defective unloading component 7. If the steel plate is qualified, the fixed box 4 is controlled to move forward by the sliding control component 5, and then the steel plate is placed back on the surface of the conveyor belt 2 by the steel plate picking mechanism 3, and the above steps are repeated to perform continuous testing.

[0025] like Figure 1 As shown, the steel plate picking mechanism 3 includes a first mounting frame 301, and the first mounting frame 301 is fixedly connected to the top surface of the test bench 1, and a first electric push rod 302 is fixedly installed on the top surface of the first mounting frame 301, and an electromagnet 303 is fixedly connected to the telescopic end of the first electric push rod 302. It should be noted that, by the operation of the first electric push rod 302, its telescopic end is driven to extend, thereby driving the electromagnet 303 to descend, so that the electromagnet 303 contacts the surface of the steel plate, and the steel plate is adsorbed by the electromagnet 303, and the steel plate can be controlled to move up and down by the first electric push rod 302.

More specifically, by symmetrically arranging the two groups of steel plate picking mechanisms 3, the steel plates are adsorbed and grasped at two positions, making the transportation of the steel plates more stable.

[0027] like Figure 2As shown, the sliding control component 5 includes a motor 501, and the motor 501 is fixedly installed on the back of the test bench 1.

It should be noted that, by driving the telescopic end of the third electric push rod 702 to extend, the supporting plate 701 is pushed to rotate around the surface of the fixed box 4, so that the steel plate on the surface of the supporting plate 701 can slide to the front side under the action of gravity, thereby completing the unloading of defective products.

[0030] When the steel plate is below the test bench 1, the fixed box 4 is controlled to move forward by the sliding control component 5, so that the middle part of the test bench 1 is exposed, and then the steel plate is grabbed and lifted by the steel plate picking mechanism 3, and then the fixed box 4 is reset by the sliding control component 5, and the steel plate is placed on the surface of the defective unloading component 7 in cooperation with the steel plate picking mechanism 3, and the steel plate is subjected to an extrusion test by the testing component 6. The strength of the steel plate can be evaluated by observing the deformation of the steel plate. If the steel plate is unqualified, the steel plate is conveyed to the interior of the defective box 8 for storage by the defective unloading component 7. If the steel plate is qualified, the fixed box 4 is controlled to move forward by the sliding control component 5, and then the steel plate is placed back on the surface of the conveyor belt 2 by the steel plate picking mechanism 3. Continuous testing can be performed by repeating the above steps. In use, the effect of facilitating rapid strength testing of the steel plate is achieved. Automatic loading and unloading can be carried out during the test, and there is no need to manually transport the steel plate to or away from the surface of the device, which makes the test process more time-saving and labor-saving, and improves the test efficiency.
