AI Technical Summary

Technical Problem

Existing material handling mechanisms have shortcomings in terms of space adaptability, operational reliability, and cost control, and cannot meet the needs of modern high-precision, compact, and low-cost stamping production. In particular, they cannot be installed or have a short service life in small precision stamping parts and multi-station designs, resulting in low production efficiency and high mold maintenance costs.

Method used

The compact blanking die automatic flipping and supporting mechanism adopts a built-in flipping structure design. It uses a linkage structure of nitrogen cylinder drive and spiral spring reset to realize synchronous flipping and precise reset of the supporting plate, reduce installation space requirements, improve action synchronization and reset reliability, and reduce manufacturing costs by using industry-standard parts.

Benefits of technology

It solves the problem of material jamming caused by sagging after trimming thin sheet metal, improves production efficiency by more than 30%, reduces downtime by more than 80%, increases product qualification rate to 99.8%, and significantly reduces mold maintenance costs.

Abstract

The application is suitable for the technical field of cold stamping die, and provides a compact automatic turnover material supporting mechanism of blanking die, which comprises a base fixed to a lower die seat of the blanking die, a turnable material supporting plate, a pivot pin, a reset assembly and a driving assembly fixed to an upper die seat of the blanking die; a mounting groove for accommodating the material supporting plate is formed in the top of the base, the material supporting plate is hinged in the mounting groove of the base through the pivot pin and can be reciprocally turned around the axis of the pivot pin between a material supporting station and an avoiding station; the reset assembly is internally installed in the base and is used for driving the material supporting plate to reset to the material supporting station; the driving assembly is used for driving the material supporting plate to turn to the avoiding station when the die is closed. The application solves the core problem of sheet metal sagging and clamping through the turnover material supporting structure, has a compact overall structure, reduces the installation space by more than 52% compared with a standard material supporting mechanism, is completely synchronous with the opening and closing of the die, has high reset precision, long service life, low manufacturing cost and strong adaptability.
