Composite Deep Drawing Die for Integrated Wheel Hub and Its Technology

Abstract

The invention relates to the field of plate deep drawing forming dies and processes of the plate deep drawing forming dies, in particular to a composite deep drawing die with a hub integrally formed and a process of the composite deep drawing die. The composite deep drawing die has the advantages that the traditional design thought of a vertically paired die is changed, a combination die (an upper die, a middle die and a lower die) are redesigned, the process action which cannot be completed by the paired die can be completed, side pressing, flanging, deep drawing, reverse deep drawing, piercing and blanking, squeezing, side cutting and other processes are completed continuously, and the process is compact and efficient; a hub ring and a spoke plate can be integrally formed, welding and riveting are eliminated, and the mechanical performance of a finished product is higher; a raw flat plate can be used as raw materials, and the performance is better than that of a raw material open flat plate formed in a splitting mode; compared with a traditional production line, the die enables customers to save uncoiling, flattening and welding equipment and process circulating auxiliary equipment.

Description

technical field [0001] The invention relates to the field of dies for sheet material deep drawing and the technology thereof, in particular to a composite deep drawing die for integrated forming of a wheel hub and the technology thereof. Background technique [0002] The automobile wheel hub includes outer rim, inner rim, rim, spoke plate, shaft hole and fastening hole. The middle of the outer rim and inner rim is the rim, and there is a shaft hole in the middle of the spoke plate, and there are several fastening holes around the shaft hole. , the inner rim is formed between the web and the rim. (As shown in the picture) There are many kinds of process routes for automobile wheel hub processing. The traditional split manufacturing is to form the spoke plate and the rim ring separately. The rim ring is first rolled and then welded, and then riveted or welded with the spoke plate; there is also an integral die-casting forming Yes, but the material and mechanical properties ar...

Problems solved by technology

[0003] At present, most of the wheels of engineering vehicles are split, with a long production process and many production equipments. The batch advantages in terms of efficiency, quality consistency and cost are not obvious. The integrated production of engineering wheels has become a new topic in the wheel industry.
