Description

Technical Field

[0001] The utility model relates to a milling tooling for a die punch, belonging to the technical field of tooling fixtures. Background Art

[0002] Die punches are mainly used for stamping. Common types are A-type punches and T-type punches. The structure of a punch generally includes a rod body and an anti-detachment cap at the head. Generally, when the diameter of the rod body is less than 3.5 mm, an A-type punch is selected. When the diameter of the rod body is greater than 3.5 mm, such as 6 mm, 8 mm, 10 mm, 12 mm, and within 18 mm, a B-type punch can be used.

[0003] The common rod body and anti-detachment cap are cylindrical. The size of the anti-detachment cap is larger than that of the rod body. A punching head with the same shape as the stamping process is provided below the rod body. The structure of the stamping die varies greatly. During installation, for some punches, due to space size limitations, the rod body or the anti-detachment cap needs to be machined by cutting to be installed smoothly. This requires milling the punch. Fixtures are needed during processing, and generally a vise is used for clamping. When clamping, a dial indicator is used to horizontally correct the axial direction of the outer peripheral surface to ensure its axis is horizontal, so as to process a plane with a higher flatness accuracy. However, this kind of fixture has a long clamping time and time-consuming installation and adjustment. Summary of the Utility Model
