Abstract

The invention belongs to the technical field of oil sprayer body forging, and discloses a guide-pin-based multidirectional closed forging technology and device for a special-shaped oil sprayer body. The technology includes the steps that a bar with the diameter slightly smaller than the minimum diameter of a forge piece is adopted to be fed, and the blank is heated to the forging temperature through a medium-frequency induction furnace and placed into the closed forging device; the device can perform lateral mold assembling under the effect of guide pins, the whole closed forging device moves downwards after a left female mold and a right female mold are locked through locking blocks, and the blank is molded under the effect of an upper male mold and a lower male mold; in the process that the closed forging device moves upwards after molding, the upper male mold is released, the left female mold and the right female mold are opened, and a workpiece is jacked out through the lower male mold. According to the technology and device, due to multidirectional parting, one-step closed forging molding of the special-shaped oil sprayer body is achieved, the forging technology is simplified, production efficiency and product performance are improved, and mechanization and automation can be easily achieved.

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...
