[0002] Metal plates are widely used in the industrial field. In order to ensure that the quality of metal plates is qualified and the bending resistance meets the use requirements, it is necessary to conduct bending resistance tests on the metal plates after production.

[0022] Please refer to the attached Figure 1-3 A bending resistance detection device for a metal plate 2 comprises a base plate 1, fixed support plates 4 are connected to both sides of the upper surface of the base plate 1, one end of the support plate 4 away from the base plate 1 is connected to a fixed transverse plate 5, a fixed hydraulic rod 6 is connected to the lower surface of the transverse plate 5, one end of the hydraulic rod 6 away from the transverse plate 5 is connected to a fixed connecting plate 7, one end of the connecting plate 7 away from the hydraulic rod 6 is connected and fixed with a plurality of pressure detectors 8, one end of the pressure detector 8 away from the connecting plate 7 is connected to a fixed pipe sleeve 10, one end of the pipe sleeve 10 away from the pressure detector 8 is plugged with a movable rod 11, one end of the movable rod 11 in the pipe sleeve 10 is connected to a fixed elastic member 9, the elastic member 9 is a spring, the elastic member 9 is in a normal state, and one end of the elastic member 9 away from the movable rod 11 is connected and fixed to the pipe sleeve 10.

[0023] By installing multiple telescopic structures consisting of movable rods 11, pipe sleeves 10 and elastic parts 9 on the lower surface of the connecting plate 7, the multiple telescopic structures are used to transmit the reaction forces of different metal plates 2 on the extrusion mechanism to the pressure detector 8, so that the device can perform bending detection on multiple metal plates 2 at the same time, thereby improving the bending detection speed of the metal plates 2.

[0024] A rectangular block 3 is connected and fixed to the lower side of one side opposite to the other of the two support plates 4. A plurality of slots for placing the metal plates 2 are provided on the upper surface of the rectangular block 3. The metal plates 2 are placed in the slots.

[0025] A T-block 16 is connected and fixed at the end of the movable rod 11 away from the pipe sleeve 10, and a sliding groove 17 with a "convex"-shaped longitudinal section is provided at both ends of the T-block 16. Then, a slider 15 is slidably connected in the sliding groove 17. A pressure plate 14 is slidably connected to the end of the T-block 16 away from the movable rod 11. The pressure plate 14 is connected and fixed to the slider 15. The side of the pressure plate 14 away from the slider 15 contacts the metal plate 2, and then through grooves connected to the sliding groove 17 are provided on the front and rear sides of the T-block 16, and a screw 12 is inserted in the through groove. One end of the screw 12 in the through groove is connected and fixed to the slider 15, and nuts 13 are slidably connected to the front and rear sides of the T-block 16. The nut 13 is threadedly connected to the screw 12.

[0026] By contacting the extrusion structure composed of the T-block 16, the pressure plate 14 and the slider 15 on the upper surface of the metal plate 2, and adjusting the distance between the pressure plate 14 and the T-block 16, the contact area between the extrusion structure and the metal plate 2 is adjusted, thereby solving the problem of requiring multiple detection equipment when testing the influence of different contact areas on the bending of the metal plate 2.

[0027] In order to ensure that there is not too much gap between the T-block 16 and the pressure plate 14 to affect the accuracy of the detection data, multiple grooves are opened on the left and right sides of the T-block 16, and connecting blocks 18 are inserted into the grooves. The connecting block 18 is connected and fixed to the pressure plate 14 at one end away from the groove, and multiple connecting blocks 18 are used to reduce the gap between the T-block 16 and the pressure plate 14.

[0028] In order to facilitate the determination of the distance between the two pressing plates 14 and the center of the T-block 16 , scales extending toward the edges on both sides are marked on both sides of the front surface of the T-block 16 .

[0029] The specific operation process of the utility model is as follows: a plurality of metal plates 2 are placed in a plurality of slots respectively, and then the hydraulic rod 6 is started to push the extrusion structure composed of the T-block 16, the pressure plate 14 and the slider 15 to extrude the metal plates 2. By adjusting the distance between the pressure plates 14 and the T-block 16 on both sides of the T-block 16, the pressure required for the bending of the metal plates 2 under different pressure areas can be detected.

[0030] When the movable end of the hydraulic rod 6 drives the extrusion structure to pressurize the metal plate 2, the movable end of the hydraulic rod 6 drops, and the pressure is transmitted to the T-block 16 through the pressure detector 8, the elastic member 9 and the movable rod 11 (the elastic member 9 is gradually compressed when the movable end of the hydraulic rod 6 is gradually extended). The T-block 16 then extrude the metal plate 2. When one of the metal plates 2 is bent, the extrusion force of the elastic member 9 in contact with the metal plate 2 is reduced, thereby reducing the pressure feedback applied to the pressure detector 8. However, this does not affect other metal plates 2 from continuing to be extruded by the hydraulic rod 6 until all metal plates 2 are extruded and bent under the extension of the movable end of the hydraulic rod 6.

[0031] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
