[0002] The punch die used in the production of manifold is composed of upper and lower core rods, which are divided into upper and lower core rods. The upper core rod is fixed on the die, and the pipe is pushed into the die from the right side and wrapped around the upper core rod. The lower core rod is inserted into the die from the left side and enters the manifold. The bottom surface of the upper core rod and the top surface of the upper core rod are processed with the same slope, and the slope is overlapped to form a cylindrical shape, which fits the inside of the manifold to ensure the stamping size. In the existing production process, two personnel are engaged in production operation. Operator A wraps the manifold around the upper core rod, and operator B inserts the lower core rod on one side. After the stamping production is completed, operator B pulls out the lower core rod, and operator A takes out the manifold product from the die.
