[0025] See also Figure 1-4 , the utility model provides a technical solution:

[0026] Aluminum-magnesium alloy tensile test fixture, including a support plate 1, the upper left and upper right parts of the support plate 1 are fixedly connected to a fixed plate 2, the upper left and upper right parts of the support plate 1 are interpenetratingly connected to a tensile device 3, and the two tensile devices 3 are interpenetratingly connected to the two fixed plates 2 respectively;

[0027] In this embodiment, the stretching device 3 includes a telescopic cylinder 31, and two telescopic cylinders 31 are provided. The output ends of the two telescopic cylinders 31 are fixedly connected to a connecting plate 32, and a cross bar 33 is fixedly connected between the two connecting plates 32. The right end of the cross bar 33 is fixedly connected to a support plate 34. The two telescopic cylinders 31 are fixedly connected to the support plate 1; the two support plates 34 are respectively connected to the two fixed plates 2 through an interlaced connection; the two stretching devices 3 are symmetrically distributed.

[0028] Through the above scheme: the aluminum-magnesium alloy material is clamped by setting a stretching device 3, and the two connecting plates 32 can be pushed together by two telescopic cylinders 31 to telescopically push the position of the cross bar 33 and the support plate 34 on the cross bar 33, so as to perform a stretching process on the aluminum-magnesium alloy material clamped and fixed on the support plate 34.

[0029] The cam 348 is fixedly connected to the upper and lower parts of the cam 349, and the cam 349 is fixedly connected to the lower part of the cam 349. The cam 349 is fixedly connected to the lower part of the cam 349. The cam 349 is fixedly connected to the lower part of the cam 349. The cam 349 is fixedly connected to the lower part of the cam 349. The cam 349 is fixedly connected to the upper and lower parts of the cam 349.

[0030] Through the above scheme: the aluminum-magnesium alloy is clamped and fixed by setting the support plate 34, the aluminum-magnesium alloy material placed on the plate body 341 is clamped by the clamping frame 346 and the plate body 341, and the two fastening screws 347 are respectively passed through the clamping frame 346 and the two support blocks 342 for interlaced connection, so that aluminum-magnesium alloy materials of different thicknesses can be clamped and fixed. At the same time, the No. 2 anti-slip pad 345 and the No. 4 anti-slip pad 350 can provide anti-slip protection for the clamping and fixing process of the aluminum-magnesium alloy material. The plate body 341 and the splint 348 can jointly perform the clamping and fixing process of the softer and smoother aluminum-magnesium alloy material in a bent state. The No. 1 anti-slip pad 343 and the No. 3 anti-slip pad 349 can provide anti-slip protection for the clamping and fixing process of the softer and smoother aluminum-magnesium alloy material in a bent state.

[0031] It should be noted that the present invention is an aluminum-magnesium alloy tensile test fixture. During use, the aluminum-magnesium alloy plate to be subjected to the tensile test is placed on two support plates 34. The two support plates 34 provide a stable support surface for the aluminum-magnesium alloy plate. The two clamping frames 346 are respectively connected to the two plate bodies 341. This step ensures that the clamping frames 346 can be firmly fixed on the support plates 34. The two No. 2 anti-skid pads 345 and the two No. 4 anti-skid pads 350 are in contact with the aluminum-magnesium alloy plate. The design of these anti-skid pads is In order to increase the friction between the clamp and the aluminum-magnesium alloy plate and prevent the plate from sliding during the stretching process, the positions of the two clamping frames 346 are fixed by the fastening screws 347 on the left and right, thereby achieving the clamping and fixation of aluminum-magnesium alloy plates of different thicknesses. When the aluminum-magnesium alloy plate is soft and smooth, in order to increase the stability of the clamping, the aluminum-magnesium alloy plate can be folded. The folding parts are respectively located between the left plate body 341 and the left clamping plate 348, and between the right plate body 341 and the right clamping plate 348. The positions of the two clamping plates 348 are moved so that the No. 1 anti-slip pad 343 and the No. 3 anti-slip pad 349 contact the folded part of the aluminum-magnesium alloy plate. These anti-slip pads not only provide additional friction, but also protect the aluminum-magnesium alloy plate from being damaged during the clamping process. The positions of the two clamping plates 348 are fixed by nuts to complete the clamping and fixation of the soft and smooth aluminum-magnesium alloy plate. The telescopic cylinders 31 on the two stretching devices 3 work simultaneously to push the two connecting plates 32. This driving force is transmitted to the cross bar 33 and the support plate 34 through the connecting plate 32. Since the aluminum-magnesium alloy plate is clamped and fixed on the support plate 34, this driving force will cause the aluminum-magnesium alloy plate to undergo tensile deformation in the longitudinal direction. By observing and analyzing the data during the stretching process (such as tensile force, deformation, etc.), the mechanical properties of the aluminum-magnesium alloy material can be evaluated. After the tensile test, the fastening screws and nuts can be loosened, and the aluminum-magnesium alloy plate and the various components of the clamp can be removed for cleaning and maintenance. According to the data results of the tensile test, the performance of the aluminum-magnesium alloy material can be evaluated and analyzed.
