Multistation manifold pipe end forming device

Abstract

The invention relates to a structure of a machining equipment unit for automobile parts, in particular to a multistation manifold pipe end forming device for machining an exhaust manifold of an automobile engine. The device comprises a pair of an upper die and a lower die which can be jointed mutually, wherein the upper die and the lower die are jointed to form an inner cavity which is adaptive to the shape of a manifold to be machined and can be used for clamping and fixing the manifold; four hydraulic cylinder supports are fixedly arranged on a substrate of the lower die, and each hydraulic cylinder support is provided with a hydraulic cylinder; and a circular pipe end sizing die head, a circular pipe end cutting die head, a shaped pipe end forming die head and a shaped pipe end cutting die head are driven by stretching parts of the four hydraulic cylinders respectively. The multistation manifold pipe end forming device has high adaptability and is convenient to install and use; and the pipe end of an integral manifold can be formed at one time in one process, so a positioning error caused by multiple positioning is prevented, the machining accuracy of products is improved, and the rejection rate is reduced.

Description

technical field [0001] The invention relates to a component structure of processing equipment for automobile parts, in particular to a multi-station manifold pipe end forming device for processing automobile engine exhaust manifolds. Background technique [0002] The automobile engine exhaust manifold is a special-shaped tubular part with a relatively complex shape. Its main body is a curved structure. Among the two pipe ends, one end is an ordinary circular pipe end, and the other end is a special-shaped pipe end with a special-shaped structure. Due to its complex shape, the traditional processing process needs to go through multiple processes to complete the forming and cutting of the nozzles at both ends. The processing process is complicated, and multiple positionings cause positioning reference errors, which makes the processed products have a high scrap rate and increases manufacturing costs. .
