[0002] A horizontal and vertical combustion test machine is a professional device for testing the combustion performance of materials, including a combustion chamber, a specimen clamping device, a burner, etc. The specimen clamping device can firmly fix the specimen to ensure that the test is carried out in a horizontal or vertical state. During the test, the sample is placed in a specific fixture to make it in a horizontal or vertical state, and then the sample is ignited by an ignition source. Conditions such as the intensity, duration of the flame, and the distance from the sample are precisely controlled to simulate the combustion conditions that the material may encounter in the actual application environment. Key parameters such as the combustion speed, combustion time, and whether the dripping ignites absorbent cotton of the specimen are observed and recorded.

[0034] The interior of the mating base plate 810 is provided with a base plate transverse cavity 819. A transverse cavity disk 820 is arranged in the base plate transverse cavity 819. A pushing spring 821 is arranged on one side of the transverse cavity disk 820. A resistance tongue 822 is fixedly arranged on the other side of the transverse cavity disk 820.

The through transverse groove 827 transversely intercepts and divides the cavity in the middle partition square seat 8. A through sealing plate 828 is inserted in the through transverse groove 827.

[0037] A pressure sensing module 829 is embedded and installed on the upper surface of the end platform disk 803. A pressure sensing disk 830 is fixedly arranged above the pressure sensing module 829. The pressure sensing disk 830 can perform pressure detection through the pressure sensing module 829.
[0038] An electromagnetic driver 831 is fixedly arranged on the surface of the combustion flame tube 6. A dial plate 832 is arranged on the electromagnetic driver 831. The electromagnetic driver 831 can drive the dial plate 832 to move horizontally. The electromagnetic driver 831 is composed of an electromagnet and a magnetically attracted metal sheet inside. The magnetically attracted metal sheet is fixed to the dial plate 832. The electromagnet attracts the magnetically attracted metal sheet to move, thereby driving the dial plate 832 to move. A vertical rod part 833 is fixedly arranged on the connecting rod part 826. The electromagnetic driver 831 can drive the dial plate 832 to move, so that the dial plate 832 squeezes and pushes the vertical rod part 833 to move along the length direction of the connecting rod part 826 towards the end where the state switching piston 825 is located.
[0039] The surface of the combustion flame tube 6 is communicatively provided with a gas branch pipe 601. A gas input pipe 602 is communicatively provided on the gas branch pipe 601. The other end of the gas input pipe 602 is communicated with the gas through a gas valve. The gas is input into the combustion flame tube 6 through the gas input pipe 602 and the gas branch pipe 601.
[0040] For the raw material horizontal and vertical combustion test machine for battery box processing of the present invention, when in use, as Figure 1 shown in the figure, the raw material of the battery box is cut into long strips and clamped in the fixed fixture 5, and is clamped horizontally or vertically as required. Figure 1 The clamping display for the vertical combustion test in the figure is shown. Gas is supplied to the combustion flame tube 6 through the gas branch pipe 601. A lighting device is arranged at the upper opening of the combustion flame tube 6, which is omitted in the figure. The gas overflowing from the combustion flame tube 6 is ignited by the lighting device, and the flame height is adjusted to the standard requirement. As Figure 7 shown in the figure, initially, the through sealing plate 828 closes the bottom of the combustion flame tube 6, so that the gas can only flow upward in the combustion flame tube 6. Move the position of the combustion flame tube 6 to below the fixed fixture 5 to conduct a combustion test on the raw material of the battery box, and observe and record parameters such as the combustion speed, combustion time, and dripping substances of the specimen. The inclined placement of the combustion flame tube 6 can reduce the probability of the dripping substances entering the combustion flame tube 6, but the inclined combustion flame tube 6 will have a certain impact on the flame, and when the flame is small, the upper opening of the combustion flame tube 6 will still be below the fixed fixture 5, and there is still a risk of the dripping substances entering.
[0041] After the test is completed, stop inputting gas into the combustion flame tube 6. At this time, the combustion flame tube 6 goes out. Drive the driving gear 808 to rotate through the driving motor 809, so that the disk-shaped worm 805 drives the limit rack 802 to move upward. In the initial upward stage, as Figure 8 shown in the figure, since the resistance tongue 822 is stuck in the annular ladder groove 818, with the separation between the air control part 811 and the mating bottom plate 810, the interaction shaft 816 is subjected to a downward pulling force. With the elastic force of the return spring 814, a negative pressure state is formed above the air control piston 813, and through the action of the pulling force and the elastic force, it is ensured that the negative pressure is sufficient. As Figure 7 shown in the figure, the negative pressure acts in the driven air pipe 824, attracting the state switching piston 825 to move, so that the through sealing plate 828 moves away from the through transverse groove 827. The dripping substances dripping on the upper surface of the through sealing plate 828 can be scraped off as the through sealing plate 828 moves to the right. When the air control piston 813 moves down to the bottom, the resistance tongue 822 will be forcibly separated from the annular ladder groove 818 through the inclined plane guidance, so that the interaction shaft 816 is pulled out of the interaction blind hole 817.
[0042] Meanwhile, structures such as the limit rack 802, the end platform disk 803, and the pressure-sensitive disk 830 move upward. Before the pressure-sensitive disk 830 moves to the position of the through horizontal groove 827, the just-through sealing plate 828 just moves out to the right from the through horizontal groove 827 to avoid interference and blockage. The pressure-sensitive disk 830 cooperates with the end platform disk 803 to scrape the drippings on the inner side wall surface of the combustion flame tube 6. Moreover, the pressure-sensitive disk 830 can sense the extrusion force when scraping the drippings in real time. When the drippings adhere too tightly, the driving motor 809 stops urgently to avoid damage to the gear structure. After the pressure-sensitive disk 830 scrapes and pushes out the drippings from the combustion flame tube 6, the upper surface of the pressure-sensitive disk 830 is flush with the upper end of the combustion flame tube 6. A side blowing air pipe can be arranged outside the combustion flame tube 6 to blow away the scrapings above the pressure-sensitive disk 830, or the combustion flame tube 6 can be controlled to tilt so that the scrapings above the pressure-sensitive disk 830 slide down naturally.
[0043] As Figure 7 As shown in the figure, position detection switches are arranged at both the limit rack 802 and the just-through sealing plate 828. The position detection switch is a prior art and will not be elaborated here. When the pressure-sensitive disk 830 is about to move to the height of the through horizontal groove 827, the position of the just-through sealing plate 828 is detected. When it is detected that the just-through sealing plate 828 has not moved completely to the right and is still stuck in the through horizontal groove 827, at this time, the pressure-sensitive disk 830 and the limit rack 802 pause to move upward, and the electromagnetic driver 831 is controlled to work, so that the dial plate 832 moves to the right. The vertical rod part 833 and the connecting rod part 826 are driven by the dial plate 832 to move to the right to assist in pushing the just-through sealing plate 828 to move to the right in place, reducing the probability of equipment jamming. The above control processes can all be programmed and set through a single-chip microcomputer or a PLC.
[0044] When the limit rack 802 moves upward in place and the cleaning is completed, during the reset, the driving motor 809 rotates in reverse. Similarly, when the limit rack 802 moves downward, when the interaction shaft 816 contacts the resistance tongue 822, first, the interaction shaft 816 is subjected to an extrusion force, so that the air control piston 813 moves upward in the internal air cavity 812. When the air control piston 813 moves upward in place, the interaction shaft 816 will push open the resistance tongue 822 through the end chamfer under pressure, so that the resistance tongue 822 is reinserted into the annular ladder groove 818; during the above process, the just-through sealing plate 828 is pushed by the positive pressure in the driven air pipe 824 to reinsert into the through horizontal groove 827 to restore the initial state.
