[0002] Aluminum profile is a very important metal material. It has many unique advantages and characteristics, which makes it widely used in various fields.

[0003] Aluminum profiles are also used in the construction industry and automobile manufacturing. For safety reasons, there are certain requirements for the bending resistance of aluminum profiles. Usually, after the production of aluminum profiles, the bending resistance of aluminum profiles needs to be tested. When testing the bending resistance of aluminum profiles, the aluminum profiles are usually fixed with fixing tools, and then the aluminum profiles are impacted with a detection device. The bending resistance effect of the aluminum profile is obtained according to the bending degree of the aluminum profile. However, during the detection process, usually only a single impact force can be tested, and it is difficult to obtain the bending resistance of aluminum profiles under different conditions.

Through the above structure, the aluminum profile is not easily slipped out of the fixing groove when it is impacted during the detection process, thereby improving the stability during the detection process.

[0009] Preferably, a concave hole is opened in the middle of the rubber pad; the concave holes are provided in multiple groups on the rubber pad and are arranged in an array. Through the above structure, the rubber pad has an adsorption effect on the aluminum profile, making the aluminum profile more stable and safe.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 to Figure 2 As shown, an aluminum profile anti-bending detection equipment described in an embodiment of the utility model comprises a detection platform 1; a pair of support frames 11 are fixedly connected to the top of the detection platform 1; a pair of adjusting screws 12 are rotatably connected to the top of the detection platform 1; the adjusting screws 12 penetrate the support frame 11 and extend to the top of the support frame 11; a handle 13 is fixedly connected to the top of the adjusting screw 12; an adjusting block 14 is threadedly connected to the middle of the support frame 11; a fixing groove 15 is opened at the end of the adjusting block 14; a fixing screw 16 is threadedly connected to the top side wall of the fixing groove 15; a fixing plate 17 is rotatably connected to the end of the fixing screw 16; the fixing plate 17 is arranged inside the fixing groove 15; a guide rod 18 is fixedly connected between the top inner side wall and the bottom inner side wall of the fixing groove 15; the guide rod 18 penetrates the wall of the fixing plate 17, and is slidably connected to the fixing plate 17 Next, during operation, the aluminum profile to be tested is placed in the middle position of the support frame 11, and the aluminum profile is placed inside a pair of fixing grooves 15. The fixing screw 16 is rotated to move the fixing plate 17 downward, and the aluminum profile is clamped and fixed. At this time, the impact device is used to impact and collide the aluminum profile, and the bending strength of the aluminum profile is obtained by observing the bending degree of the aluminum profile. After one test, the adjusting screw 12 is rotated by holding the handle 13, and the adjusting screw 12 drives the adjusting block 14 to move up and down. The height of the aluminum profile is changed by changing the position of the adjusting block 14. Because the height of the aluminum profile is changed, the impact force on the aluminum profile is changed. Therefore, the bending resistance under different degrees of impact can be obtained, which improves the diversity of the test results and better reflects the bending strength of the aluminum profile.

[0023] like Figure 2As shown, the bottom side wall of the adjusting block 14 is fixedly connected to a first connecting plate 2; the bottom side wall of the testing platform 1 is fixedly connected to a pair of second connecting plates 21; the second connecting plate 21 is arranged below the first connecting plate 2; the side wall of the second connecting plate 21 is hinged with a gas spring 22; the end of the gas spring 22 away from the second connecting plate 21 is hinged to the side wall of the first connecting plate 2. When working, by arranging a gas spring 22 between the adjusting block 14 and the testing platform 1, when the impact device hits the aluminum profile, a large impact force will be generated, which will cause the aluminum profile to drive the adjusting block 14 to vibrate, and at the same time, the adjusting block 14 will share part of the impact force on the aluminum profile, which may cause the adjusting block 14 to break or be damaged. At this time, the gas spring 22 between the adjusting block 14 and the testing platform 1 is used to reduce the shock of the adjusting block 14 when it is impacted, thereby reducing the vibration aftershocks on the adjusting block 14, thereby improving the safety of the adjusting block 14 during operation and the service life of the adjusting block 14.

[0024] like Figures 2 to 4 As shown, the side wall of the fixing plate 17 is fixedly connected with a rubber pad 3; the rubber pad 3 is located on the side wall of the fixing plate 17 away from the fixing screw 16. When working, the friction between the fixing plate 17 and the aluminum profile is increased by arranging the rubber pad 3 on the fixing plate 17, thereby improving the fixing effect of the fixing plate 17 on the aluminum profile, so that the aluminum profile is not easily slipped out of the fixing groove 15 when impacted during the detection process, thereby improving the stability during the detection process.

[0025] like Figure 4 As shown, the side wall of the fixing plate 17 is fixedly connected with a rubber pad 3; the rubber pad 3 is located on the side wall of the fixing plate 17 away from the fixing screw 16. When working, the friction between the fixing plate 17 and the aluminum profile is increased by arranging the rubber pad 3 on the fixing plate 17, thereby improving the fixing effect of the fixing plate 17 on the aluminum profile, so that the aluminum profile is not easily slipped out of the fixing groove 15 when impacted during the detection process, thereby improving the stability during the detection process.

[0026] like Figures 2 to 4 As shown, a wax block 5 is fixedly connected to the top of the adjusting block 14; the wax block 5 is sleeved on the fixed screw 16 and is in sliding fit with the fixed screw 16. During operation, the fixed screw 16 is lubricated by the wax block 5, which can reduce the problem of jamming of the fixed screw 16 during rotation, thereby improving the stability of the fixed screw 16 during operation.

[0027] like Figure 1 and Figure 3As shown, the surface of the handle 13 is provided with anti-skid grooves 6; the anti-skid grooves 6 are provided in multiple groups on the handle 13 and are arranged in a circular array. During operation, by providing the anti-skid grooves 6 on the handle 13, when the staff member rotates the handle 13, the friction between the staff member's hand and the handle 13 is increased, the possibility of slipping when the handle 13 is rotated is reduced, and the stability during operation is improved.

[0028] During operation, the aluminum profile to be tested is placed in the middle position of the support frame 11, and the aluminum profile is placed in a pair of fixing grooves 15. The fixing screw 16 is rotated to move the fixing plate 17 downward, and the aluminum profile is clamped and fixed. At this time, the impact device is used to impact and collide the aluminum profile, and the bending strength of the aluminum profile is obtained by observing the bending degree of the aluminum profile. After one test, the adjusting screw 12 is rotated by holding the handle 13, so that the adjusting screw 12 drives the adjusting block 14 to move up and down, and the height of the aluminum profile is changed by changing the position of the adjusting block 14. Because the height of the aluminum profile is changed, the impact force on the aluminum profile is changed, so the bending resistance under different degrees of impact can be obtained. A gas spring 22 is provided between the adjusting block 14 and the testing platform 1, and when the impact device hits the aluminum profile, a large impact force is generated, which causes the aluminum profile to drive the adjusting block 14 to generate Vibration, and at the same time, the adjustment block 14 shares part of the impact force on the aluminum profile, which may cause the adjustment block 14 to break or be damaged. At this time, the gas spring 22 between the adjustment block 14 and the test bench 1 is used to reduce the shock of the adjustment block 14 when it is impacted. A rubber pad 3 is provided on the fixing plate 17 to increase the friction between the fixing plate 17 and the aluminum profile, thereby improving the fixing effect of the fixing plate 17 on the aluminum profile. By providing a plurality of groups of concave holes 4 on the rubber pad 3, when the aluminum profile reversely extrude the rubber pad 3, the rubber pad 3 is deformed and part of the air inside the concave hole 4 is discharged, so that the rubber pad 3 has an adsorption effect on the aluminum profile. By lubricating the fixing screw 16 with the wax block 5, the problem of jamming when the fixing screw 16 is rotated can be reduced. By providing an anti-slip pattern 6 on the handle 13, when the staff member rotates the handle 13, the friction between the staff member's hand and the handle 13 is increased, thereby reducing the possibility of slipping when the handle 13 is rotated.
