AI Technical Summary
In existing technologies, the cannula is prone to kinking during the vacuuming process, which can obstruct the exhaust channel and affect the vacuuming efficiency. Furthermore, using wire for repair poses a risk, as it may damage the integrity and sealing of the cannula.
An engine exhaust manhole sealing tube bending shaping machine was designed, including internal and external components. It uses silicone rubber heating pads and digital display temperature controller to pre-bend and shape the tube to form a 90° bend, ensuring unobstructed exhaust passage.
By pre-shaping the curvature of the insertion tube, problems such as kinking and blockage are avoided, ensuring smooth flow during the vacuuming process, improving production efficiency and safety, and simplifying the operation process.
