Progressive Punching is an efficient self-riveting process of fixed rotor, which can realize large-scale and precise riveting operation and is suitable for mass manufacturing production line. The following is the introduction of progressive rotor self-riveting process:
First, determine the type and specification of the stator and rotor required for riveting, and prepare the rivets and riveting machines required for riveting. Rivet size should match the hole size of stator and rotor to ensure tight fit and firmness.
According to the size and riveting requirements of stator and rotor, the rivet is machined into the corresponding length and shape. Progressive punch riveting machine also needs to adjust, set, calibrate the position of the riveting head, pressure, speed and other parameters.
Insert the rivet into the stator hole, and start the progressive punching riveting machine with electricity. The rivet will exert force on the rivet head according to the set parameters, and form a large number of threaded processes on the inner wall of the stator hole, so that the rivet deformation is firmly connected with the stator.
Wait for the rivet deformation, riveting process is complete. The remaining rivet tail should be cut off and inspected after riveting is completed to ensure that the riveting is firm and reliable and the transmission system runs smoothly.
In general, the process of progressive impact fixed rotor self-riveting can improve the production efficiency, but also ensure the precision and stability of riveting. However, riveting machine adjustment requires specialized skills, so an operator familiar with the riveting process is required.
