AI Technical Summary
Traditional three-way catalytic converter diameter reduction molds are prone to ellipticity deviation, axial bending, uneven wall thickness, and springback during the shell diameter reduction process, resulting in low production efficiency, high cost, and the need for secondary or multiple fine-forming processes.
The composite mold assembly includes a fixed mold base, side mold frame, upper stamping base, forming module and diameter reduction unit. The inner mold core is driven by a hydraulic cylinder to cooperate with the inner shrinking block to realize the step-by-step forming and dynamic shaping of the shell. The relative movement of the guide shaft and the outer section tube provides dynamic support and spinning to ensure the accuracy of the inner diameter of the shell.
It effectively corrects ovality and wall thickness unevenness, significantly improves roundness and coaxiality, eliminates or reduces springback, ensures dimensional stability after diameter reduction, and improves production efficiency and reduces costs.
