Abstract

The invention belongs to the technical field of fuel injector body forging, and relates to a multi-directional block forging process and device for a special-shaped fuel injector body based on a guide pin. The billet is heated to the forging temperature by an intermediate frequency induction furnace, and placed in the closed forging device. The device can be clamped sideways under the action of the guide pin. Under the action of the upper and lower punches, the billet is formed. After forming, the forging device is closed and the upper punch is withdrawn, the left and right dies are opened, and the lower punch ejects the workpiece. The invention realizes one-step closed forging forming of the special-shaped fuel injector body through multi-directional splitting, simplifies the forging process, improves production efficiency and product performance, and is easy to realize mechanization and automation.

Description

technical field [0001] The invention belongs to the technical field of fuel injector body forging, and in particular relates to a block forging device and process for a special-shaped fuel injector body. Background technique [0002] Such as figure 1 As shown, the special-shaped fuel injector body 1 has a small diameter of the intermediate transition section 11 and large dimensions at both ends. Generally, open die forging is used, and there are many forming processes, requiring more operators and equipment. After forging, it needs to be cut off. Flash has problems such as low production efficiency and long production cycle. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of low forging production efficiency and long production cycle of the fuel injector body in the prior art, and provide a multi-directional block forging device and its process based on the guide pin for the special-shaped fuel injector body. [0004] Th...
