[0042] In a specific embodiment, the movable member 360 and the loading member 350 are connected by threads. The movable member 360 abuts against the sample 353 under thread spinning and gradually increases the applied pressure, so that the sample 353 can be firmly fixed by the movable member 360 and the loading member 350 .

The electromagnetic induction coil can directly heat the entire loading part 350, and the heat of the loading part 350 is transferred to the sample 353.

[0050] In a specific embodiment, the heating unit may be in the form of a resistance wire heating or the like.

[0051] Figure 4 , Figure 5 and Figure 8 It is shown that in one embodiment, the overpressure protection module 340 may include a pressure relief hole 363 provided on the movable part 360, a pressure relief pipe 341 connected to the base and in gas communication with the loading unit 330, an air outlet branch 343 provided on the pressure relief pipe 341, a regulating valve 342 provided on the air outlet branch 343, a pressure relief branch 344 provided on the pressure relief pipe 341, and an explosion-proof membrane 345 sleeved on the outlet of the pressure relief branch 344. The regulating valve 342 can be opened to allow the high-pressure air in the body 331, and the pressure of the explosion-proof membrane 345 being broken by the air pressure is much lower than that of other parts. When the sample 353 is broken, the surge of air pressure first breaks through the explosion-proof membrane 345, and then the high-pressure air is discharged from the explosion-proof membrane opening, so as to avoid the high-pressure air from damaging other parts and improve the service life of the equipment.

[0052] In a specific embodiment, the pressure relief holes 363 of the movable part 360 are a plurality of evenly distributed arc holes, which can increase the pore area to prevent the high-pressure gas from being unable to be discharged in time when the sample 353 is broken by the high-pressure gas, thereby damaging other components and improving the service life of the equipment.

[0053] Figures 1 to 3 The pressure control module may include a plurality of pressure control units 100 in one embodiment, and the plurality of pressure control units 100 are respectively connected to a plurality of loading units 330, a forward detection unit 320 and a lateral detection unit 310.

The support frame is arranged on one side of the frame 300, and the three-dimensional visual recognition system is arranged on the support frame. The three-dimensional visual recognition system detects the shape and size of the sample 353 through the first window 400.

[0055] In the present invention, Figure 1-Figure 8The working process of the present invention in some embodiments is shown. The sealing gaskets 352 are clamped on both sides of the sample 353, and then the sample 353 is placed in the loading part 350.

The high-pressure gas is supplied through the gas supply unit, and then the pressure control unit 100 controls the output of the gas of the specified pressure to the gas inlet 336. The high-pressure gas enters the loading part 350 and reaches one side of the sample 353. The high-pressure gas generates pressure on the sample 353 and deforms the sample 353. At this time, if the positive detection unit 320 is detected, the guide is not installed. The extension member 370 detects the deformation data of the front side of the sample 353 through the first window 400 and feeds back the data to the control unit. If the lateral detection unit 310 is to be detected, the extension member 370 needs to be installed in the movable member 360. The lateral detection unit 310 can detect the distance of the extension member 370 changing front and back through the second window 410, thereby converting the data into the actual maximum shape change of the sample 353 and feeding back the data to the control unit. If the sample 353 is ruptured by high-pressure gas, the high-pressure gas will flow from the second channel 335 to the explosion-proof membrane 345. The explosion-proof membrane 345 will rupture due to the pressure of the high-pressure gas, and the high-pressure gas will be discharged from the pressure relief branch pipe 344 without damaging other parts of the system.

[0059] Step S3, the control unit controls the pressure control unit 100 to supply high-pressure air into the loading unit 330 and pressurize the sample 353;
