DEVICE AND METHOD FOR AUTOMOBILE COWL CROSS BAR

摘要

PURPOSE: A cowl cross bar for an automobile manufacturing device and a manufacturing method thereof is provided to mold a cowl cross bar having multiple diameters by molding on raw material, thereby reducing the weight by dropping an overlapped or a welding process. CONSTITUTION: A cowl cross bar for an automobile manufacturing device comprises a feeding unit and a rotary swaging part. The feeding unit is formed on one side of a main body frame to mold a raw material pipe. The swaging unit is formed on the other side of the main body frame and mounted with a necking tool unit for forging molding. The feeding unit installs a compression operation plate to be slid forward and backward. The compression operation plate is mounted with a clamp clamping an raw material pipe, a push-out prevention unit inserted in the core part of a rotation bracket having a through hole on the rear side and an loadable axle inserted into the inside of the raw material pipe clamped by the clamp. A protruded circle rim arranged in the through hole is formed on the front side of the rotation bracket inserted into the push-out prevention unit. The protruded circle rim has an inclined surface, and a smaller external diameter than the inner diameter of the raw material pipe.
