Its quality and processing accuracy have a decisive impact on the performance and reliability of the automotive air conditioning system. The existing automotive air conditioning duct punching operation mainly relies on manual trimming. In this process, workers can only rely on their own experience and visual observation to control the direction and size of trimming. This subjective judgment method will inevitably bring great uncertainty and deviation. Furthermore, it is difficult to ensure the consistency of force and angle during manual trimming, which will cause the surface of the cut to be uneven and a large number of burrs will be generated. The existence of these burrs seriously damages the appearance quality of the duct, and in the subsequent installation and use of the duct, it may cause a series of problems such as scratching and clogging, which brings huge hidden dangers to the normal operation of the automotive air conditioning system. In order to eliminate these burrs, it is often necessary to invest a lot of time and manpower for re-trimming. This additional process not only significantly increases the production cost, but also greatly prolongs the production cycle, resulting in a significant reduction in production efficiency. More importantly, the quality of manual trimming is extremely unstable, and the operating skills and working conditions of different workers vary significantly, which directly leads to uneven final trimming effects and difficulty in maintaining consistent product quality.
