Office Chair Wheel Riveting
Customized orbital riveting machines or pneumatic vibratory disc reverse riveting machines can be used for office chair wheel riveting, with customized orbital riveting machines offering significant technological advantages.
Traditional office chair wheel riveting often employs stamping riveting methods, but this approach has notable drawbacks in the processing of turntable components. Due to uneven stress distribution, micro-cracks are prone to form at the junction of the rivet and the turntable. Over long-term use, the rivet loosening rate can reach as high as 15%-20%, leading to wheel wobbling or even detachment. Additionally, traditional processes have poor adaptability to rivet diameters, with particularly unsatisfactory fixing effects for rivets in the 8-12mm range. The processing deformation often exceeds 0.5mm, affecting the overall flatness of the turntable.
Customized orbital riveting machines achieve breakthroughs through radial riveting technology. Their core eccentric wheel mechanism drives the rivet head to perform radial compound motion, enabling the rivet to be progressively formed within 0.3-0.5 seconds. Compared to traditional stamping riveting, this technology controls deformation to within 0.2mm, a reduction of over 60%, effectively avoiding stress concentration caused by excessive deformation of the turntable. Measured data shows that after a well-known manufacturer introduced this equipment, the defect rate of turntable components dropped from 3.2% to 0.7%, equipment uptime increased to 92%, and single-shift production capacity improved by 40%. This technology is particularly suitable for fixing scenarios involving rivets with diameters of 8-12mm. By adjusting the eccentric wheel parameters, the riveting force can be precisely controlled, ensuring a fit of over 99% between the rivet head and the turntable surface.
Pneumatic vibratory disc reverse riveting machines provide a supplementary solution. This equipment automatically sorts rivets through a vibratory disc and uses a pneumatic drive mechanism to achieve rapid riveting, completing 15-20 riveting actions per minute. Its advantages lie in its compact structure and simple operation, making it suitable for small to medium-batch production or products with simple structures like folding chairs. However, this equipment has high requirements for rivet length consistency. When the length deviation exceeds 0.1mm, rivet jamming faults are prone to occur, necessitating the use of a high-precision rivet feeding system.
In practical applications, enterprises need to select equipment based on production scale and product precision requirements. For large-scale production, it is recommended to prioritize customized orbital riveting machines. Although their initial investment is higher, long-term maintenance costs can be reduced by 35%. For small-batch or diversified production, pneumatic vibratory disc reverse riveting machines can be chosen, allowing for quick switching between different rivet specifications through modular design.
