Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum flat tube production, in particular to a bursting pressure detection mechanism for aluminum flat tubes. Background Art

[0002] An aluminum flat tube is a long, thin-walled tubular structure made of aluminum alloy material, with a flat cross-section (usually rectangular or approximately rectangular), and has the characteristics of light weight, high strength, good corrosion resistance, and smooth surface. The existing bursting pressure detection mechanism of an aluminum flat tube is driven by a driving module to seal both ends of the aluminum flat tube, and then an external water supply device supplies water to the inside of the aluminum flat tube until the aluminum flat tube bursts, and the maximum water pressure when the aluminum flat tube bursts is recorded. However, in actual use, due to the large number of length specifications of aluminum flat tubes, it is more troublesome to detect aluminum flat tubes of different lengths.

[0003] For example, the utility model with announcement number CN216816322U discloses a bursting pressure detection device for an aluminum flat tube, wherein the liquid collecting plate comprises a plate body, a liquid collecting chamber and a card slot are arranged on the plate body, the liquid collecting chamber passes through the upper end surface of the plate body upward, a liquid inlet pipe is arranged in the plate body, one end of the liquid inlet pipe is connected to the liquid collecting chamber, and the other end of the liquid inlet pipe passes through the side wall of the plate body to form a liquid inlet, the card slot is formed by the upper end surface of the plate body being recessed downward, one end of the card slot is connected to the liquid collecting chamber, and the other end of the card slot extends toward the direction of the lower pressing block and passes through the end of the plate body toward the direction of the lower pressing block. A rectangular annular sealing groove is provided on the upper end surface of the plate body, and the sealing groove surrounds the liquid collection chamber. A first sealing ring is installed in the sealing groove; when the sealing pressure plate moves downward, it can press against the first sealing ring. In the technical solution of this patent, the two ends of the aluminum flat tube are closed by an electric push rod, so that the liquid enters the interior of the aluminum flat tube from the liquid collection chamber until the aluminum flat tube bursts, and the maximum water pressure when the aluminum flat tube bursts is recorded. When testing aluminum flat tubes of different lengths, personnel need to tighten more bolts to replace testing mechanisms of different specifications, which is time-consuming and labor-intensive.
