Forming and shaping die for air inlet manifold of automobile engine exhaust system

Abstract

The invention provides a forming and shaping die for an air inlet manifold of an automobile engine exhaust system. The forming and shaping die has the advantages that the cost of production equipment can be effectively reduced and the production efficiency is increased. The forming and shaping die comprises an upper die plate and a lower die plate, wherein an upper mounting plate is mounted above the upper die plate through an upper die pin, a lower mounting plate is mounted below the lower die plate through a lower die pin, and the upper die plate and the lower die plate are in guiding connection through guide members which roll independently. The forming and shaping die is characterized by further comprising an integral forming module, an upper shell portion shaping module and a lower shell portion shaping module, wherein the integral forming module, the upper shell portion shaping module and the lower shell portion shaping module are mounted between the upper die plate and the lower die plate side by side along the transverse direction.

Description

technical field [0001] The invention relates to the technical field of automobile engine exhaust system component processing, in particular to a shaping mold for an intake manifold of an automobile engine exhaust system. Background technique [0002] An intake manifold of an automobile engine exhaust system, which is assembled and welded by an upper shell and a lower shell. figure 1 , figure 1 The middle 33 is the upper shell part in the integrated workpiece, the 34 is the lower shell part in the integrated workpiece, and the 35 is the profile center of the integrated workpiece. Since the external profile of the pipe fitting is complex, and the pipe wall of the pipe fitting is relatively Thin, one-time direct stamping forming to the design requirements is prone to cracking defects, so it is necessary to reshape the upper shell part and the lower shell part of the workpiece after preliminary forming to ensure that the pipe fittings are processed in place without cracking def...

AI Technical Summary

Problems solved by technology

In the past, the preliminary forming of the workpiece, the shaping of the upper shell, and the shaping of the lower shell required the design of three sets of molds and the use of three sets of punching machines to complete it. The equipment cost was high and the production efficiency was low.
