Structural design of pneumatic piercing fixture for car trunk support
The car trunk support assembly needed to process two holes with the coaxiality of φ0.01 mm,and it was found that using pneumatic punching fixtures for one-time processing was neces-sary to achieve the requirement of two holes with the coaxiality after analysis.Production practice proved that the use of pneumatic punching fixture not only ensured the accuracy of piercing,but also improved the processing efficiency and saved the stamping equipment.
