Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a stamping equipment for tapered bearings. Background Technology

[0002] Tapered roller bearings, also known as tapered roller bearings, are rolling bearings capable of simultaneously bearing radial and axial loads. These bearings are characterized by tapered raceway surfaces on both the inner and outer rings, which allows them to adapt well to forces in these combined directions. Depending on the application, tapered roller bearings can be classified into single-row, double-row, and four-row types.

[0003] In the existing technology, some stamping devices are prone to misalignment during the stamping process because the upper and lower dies do not have good limiting. This results in some workpieces having substandard precision after stamping. The increased failure rate leads to more waste of raw materials and a reduction in effective production time. Utility Model Content
