[0001] This application relates to the technical field of optical element manufacturing, and particularly relates to a stamping jig for diaphragm blades. Background Art

[0002] A diaphragm blade is an optical element, usually used to control the amount of light passing through an optical system. Diaphragm blades are usually installed at the position of the diaphragm (aperture). By adjusting the opening size of the blades, the intensity and distribution of the light beam can be changed.

[0003] During the manufacturing process of optical devices, the stamping of diaphragm blades is an important link. The rivets provided on the diaphragm blades are riveted by a riveting machine. Due to the large punching force of traditional riveting machines, and usually applicable to rivets whose outer diameter meets the requirements of the riveting machine and is larger than the blade rivets. And because the diaphragm blades are relatively thin and small in size, they are prone to deformation during riveting.

[0004] Based on this, this application provides a stamping jig for diaphragm blades. Utility Model Content
