How to reduce noise when processing precision metal stamping parts? 'Hardware'

Precision metal stamping parts and other products are widely used in our daily lives. With the development of science and technology, people have higher and higher requirements for precision metal stamping parts, especially in terms of production quality and technology. There are also certain requirements for the noise generated during the processing of precision metal stamping parts. So how to reduce the noise during the processing of precision metal stamping parts? The following Dongguan Hardware organizes and introduces for everyone. 1. Control gear accuracy: Basic requirements for gear accuracy: verified by practice, gear accuracy must be controlled at GB10995-887~8, linear speed higher than 20m/s gear, pitch limit deviation, ring gear radial runout tolerance, The tooth direction tolerance must be stable and reach 7-level accuracy. 2. Civilized production: More than 30% of gear transmission noise is caused by burrs and bumps. For some precision metal stamping parts, it is a passive method to remove burrs and bumps before the gearbox is assembled. 3. Ensure the accuracy of the gear blank: The accuracy of the size of the gear hole is required to be distributed around the middle difference of the deviation value of the hole, set at ±0.003~±0.005mm; if it is out of tolerance and within the range of hole design requirements, it must be classified , Respectively transferred to the gear cutting process.
