After power is turned on, the simulation of the process line conditions is completed, and the forming foil experiment is carried out. The device as a whole is also convenient for installation and disassembly.

[0035] As a preferred embodiment 2, a bendable temperature monitoring mechanism 9 is provided on one side of the box body 1, and the sensing end of the temperature monitoring mechanism 9 forms a temperature sensing cooperation with the formation tank liquid in the formation barrel 4. A water cooling pipe 6 is provided in the formation barrel 4. The temperature monitoring mechanism 9 is electrically connected to the heating mechanism 3 through a controller, and the temperature monitoring mechanism 9 is connected to both ends of the water cooling pipe 6 through the controller to form a linkage cooperation.

[0036] The controller may be a PLC controller.

[0037] It is convenient to control the temperature and ensure that the formation tank liquid is in a constant temperature state. The temperature is monitored by the temperature monitoring mechanism 9. When the temperature exceeds the set temperature, the temperature monitoring mechanism 9 transmits a signal to the controller, and the controller controls the two ends of the water cooling pipe 6 to be connected for circulating water cooling. At the same time, the controller reduces the power of the heating mechanism 3 to reduce the temperature until the set temperature is reached; when the temperature is lower than the set temperature, the temperature monitoring mechanism 9 transmits a signal to the controller, and the controller controls the two ends of the water cooling pipe 6 to be closed and not to circulate water cooling. At the same time, the controller increases the power of the heating mechanism 3 to increase the temperature until the set temperature is reached.

[0038] The temperature monitoring mechanism 9 includes a mounting base 901 disposed on the box body 1, a deformable mounting tube 902 is disposed on the mounting base 901, and a temperature sensor probe 903 is detachably sleeved and fixed on the end of the deformable mounting tube 902, and the temperature sensor probe 903 is electrically connected to the controller.

[0039] Preferably, the length of the deformable mounting tube 902 needs to be such that after the bending deformation, the temperature sensor probe 903 is placed in the formation tank solution without contacting the water cooling tube 6, thereby ensuring the accuracy of temperature measurement.

[0040] The temperature sensor probe 903 may use a ceramic insulated thermocouple of XC-14-K-12.

[0041] The heating mechanism 3 includes a spirally arranged resistance wire 301, the resistance wire 301 is electrically connected to the controller, the resistance wire 301 is coaxially embedded in the heating tank 2, an insulating heat-conducting sleeve 302 is coaxially embedded in the resistance wire 301, and the formation barrel 4 is coaxially embedded in the insulating heat-conducting sleeve 302, and the formation barrel 4 forms a heat-conducting match with the resistance wire 301 through the insulating heat-conducting sleeve 302.

Both ends of the water cooling pipe 6 are connected to an external circulating cooling water source through an electric control valve, and the electric valve is connected to a controller. When the valve is opened, the cooling water first enters the bottom of the spiral, and finally flows out from the top of the spiral, taking out the heat, and quickly reducing the heat, which is used for cooling and temperature control.

[0043] A screen 10 and a control switch 11 are provided on one side of the box 1, and both the screen 10 and the control switch 11 are electrically connected to the controller. The screen 10 is used to display the temperature, heating time, power-on value, etc., and the control switch 11 is used to adjust the temperature and start the formation device.

[0044] As a preferred embodiment 3, the negative electrode connecting plate 5 is in an inverted U shape, and the negative electrode connecting plate 5 is a pair and symmetrical about the center position of the formation barrel 4.

[0045] One of the negative electrode connecting plates 5 holds the negative electrode of the power supply. The negative electrode connecting plate 5 is used to hold the negative electrode of the power supply, so that the formation barrel 4 is also connected to the negative electrode of the power supply, and the U-shaped arrangement can also be used as a lifting ear to lift the formation barrel 4, which is convenient for the installation and removal of the formation barrel 4.

[0048] One side of the L-shaped mounting frame 7031 is vertically embedded in the mounting hole 702 and forms a limit fixation with the mounting hole 702 to ensure stability during formation, while the insulating base 701 ensures that the negative pole of the power supply is not directly connected to the positive pole of the power supply to form a short circuit. When in use, the positive pole of the power supply is clamped on the L-shaped mounting frame 7031, and the L-shaped mounting frame 7031 supplies electricity to the foil 8 through the conductive clip 7032.

The power supply is provided with an alarm. After the prompt sound is sounded, the experimental sample is taken out after the power switch is turned off, and the forming is completed. The device as a whole is also convenient to install and disassemble.
