1, free forging

Free forging is the use of impact or pressure to deform the metal between the upper and lower two irons. To obtain the required shape and size of the forgings. In heavy machinery, free forging is the only method of producing large forgings and oversized forgings.

2, die forging

Under the action of pressure or impact, the metal blank is deformed in the forging die to obtain a forging process. The forgings produced by this method are accurate in size, have a small processing allowance, and the structure can also be complicated and have high productivity.

3, forging die

The die forging of a tire is a method for producing a die forging using a tire die in a free forging device. Generally, a forging method is used for a blank, and then the tire is molded in a tire mold.

The forging method is characterized in that it includes a forging sucking hole, a wax stick, a press molding and a thermalizing process. The forging sucking hole process is a method of drawing a solid rod into a hollow pipe piece without seams; The wax strip corresponding to the inner diameter of the hollow tube is inserted into the interior of the hollow tube; the molding process is to place the hollow tube with the wax strip between the upper mold and the lower mold. The upper mold and the lower mold are respectively provided with the mold cavity. Corresponding concave-convex shape molding, when the upper mold and the lower mold are pressed together, a reinforcing rib can be formed at the periphery of the tube; the heating process is to be molded.
