Description

TECHNICAL FIELD

[0002] As a key component in energy conversion systems, the performance of heat exchangers directly affects the efficiency of the entire system. A typical heat exchanger is composed of multiple important components, including but not limited to heat exchange tubes, fins, connecting pipes, and joints. These components work together to ensure efficient heat transfer from one medium to another.

[0003] In a heat exchanger, the connecting pipe plays an important role in connecting different parts and facilitating fluid flow. To meet complex structural requirements, the connecting pipe is usually made of copper and formed into the desired shape through a bending process. To improve sealing and connection strength, the port of the connecting pipe needs special treatment. Specifically, the port of the copper pipe is processed from an original circular shape to an oval shape, which not only changes the shape of the pipe end but also requires higher assembly precision. After processing, the connecting pipe port must be reshaped to ensure quality. First, cutting is needed to make the port surface flat and consistent to ensure tight fit during connection. Then, chamfering is needed to eliminate burrs and sharp edges generated during cutting, which is crucial for preventing damage during assembly.

[0004] Although the above process is quite mature, there are still some problems in actual application. In particular, on the automated production line, the existing connecting pipe port shaping machine (such as patent CN111941088B heat exchanger connecting pipe forming integrated machine) integrates multiple functions, but the design of its automatic feeding mechanism is still insufficient. Due to the simple structure of the feeding mechanism, the connecting pipe cannot be smoothly and accurately delivered to the cutting station, affecting the shaping quality and production efficiency.
