Description

Technical Field

[0001] The invention belongs to the technical field of production of aviation oxygen system accessories, and in particular relates to an anti-deformation extrusion molding system for an ultra-thin-wall aviation oxygen bracket. Background Art

[0002] Aviation oxygen brackets are key parts in aircraft oxygen supply systems. They are ultra-thin-walled special-shaped extrusion parts that play a vital role in ensuring that aircraft crew members can inhale enough oxygen during high-altitude flights or emergency situations. The main functions of aviation oxygen brackets in aircraft oxygen supply systems are: First, as a part of the oxygen supply system, aviation oxygen brackets are mainly responsible for connecting and supporting the oxygen source and the oxygen supply equipment to ensure that oxygen can be stably and effectively delivered to each passenger. Secondly, the design of aviation oxygen brackets is crucial to the stability and reliability of the system. Since aircraft experience various complex environments and conditions during flight, such as high altitude low pressure, temperature changes, etc., oxygen brackets must have sufficient strength and stability to meet these challenges. At the same time, oxygen brackets also need to have good corrosion resistance and wear resistance to ensure their long-term stable operation. Furthermore, in an emergency, such as the failure of the cabin pressurization system, the aircraft needs to descend rapidly. At this time, the emergency oxygen supply system will ensure that all crew members and passengers have oxygen in a short time. As an important part of the emergency oxygen supply system, aviation oxygen brackets can ensure that oxygen masks can be released and provided with oxygen quickly and accurately in this case.

[0003] The existing ultra-thin-wall aviation oxygen bracket extrusion molding system was found to have shortcomings during use. First, due to the high temperature of the extruded ultra-thin-wall aviation oxygen bracket aluminum profile, there is a certain degree of stickiness between the cutter and the cutter. After the cutter cuts the aluminum profile, some aluminum chips often stick to the tip of the cutter, and the aluminum profile also sticks to the cutter, affecting the cutting of the ultra-thin-wall aviation oxygen bracket aluminum profile; second, it is not equipped with a pressure-bearing transmission component, which makes it easy for the cutter to deform when cutting the ultra-thin-wall aviation oxygen bracket aluminum profile. Therefore, it needs to be optimized and improved. Summary of the invention
