Riveting machine - how many molds do you know?
But aircraft manufacturers like to use rivets, why? Next, Rivet manufacturer will explain it for you. Let's start with a brief look at riveting, welding and threading.
1, with rivets to connect the parts into a whole, called riveting.
2, the method of joining metal or other thermoplastic materials by heating, high temperature or high pressure is called welding.
3, the use of screws and nuts for connection, referred to as screw joint.
With the continuous development of aircraft, flight speed and height continue to improve, especially after high-hardness aluminum alloy has become the main material for aircraft manufacturing, aluminum alloy is easy to deformation at high temperature and high temperature shortcomings and shortcomings. Reduced mechanical properties become more and more apparent. Resonance and stress changes make welding points very easy to break. As a result, riveting becomes the ultimate choice for connecting aircraft components.
The rivets that can be used in aircraft are naturally extraordinary. Specification strength is an important index to measure the performance of rivet. In short, high specific strength means high strength and light weight.
High-end rivets not only use materials with higher specific strength, but also require very high machining accuracy to achieve micron level control. A micron is about one-eightieth the diameter of an adult hair.
Now the aviation industry in our country has fully realized the independent guarantee of the production and supply of high-end rivets. At the same time, CNC automatic drilling and riveting technology is becoming more and more mature.
