Problems solved by technology

[0002] The forging process of the existing fuel injector generally has two processes: cold forging and hot forging. The internal structure and grains cannot fully meet the performance requirements. Moreover, the blank parts need to be cut and flashed. These cut blanks and flashes cannot be reused, resulting in waste of steel materials. At the same time, they are oxidized at high temperatures. Seriously, the fixture has worn the surface of the mold

Embodiment Construction

[0012] The present invention will be further described in conjunction with examples.

[0013] A molding process of a fuel injector, comprising the following steps:

[0014] (1) Feed the steel plate material into the cold heading machine for shearing, and cold forge the sheared material to forge the pre-forged body of the injector in the shape of a rotary body;

[0015] (2) Put the fuel injector body into the intermediate frequency furnace for heating, and the heating temperature is 800-1000°C;

[0016] (3) Put the pre-forged body of the fuel injector into the die chamber with the injector membrane cavity, and then perform final forging by the press to forge the asymmetric part of the fuel injector;

[0017] (4) Tempering the entire pre-forged body at a tempering temperature of 520-600°C, and then cooling naturally;

[0018] (5) Finally, cut off the flash on the asymmetric part of the injector.

[0019] Preferably, before heating in an intermediate frequency furnace, an anti...

Abstract

The invention discloses an oil injector forming process, comprising the following steps: (1) feeding a steel material into a cold header, shearing, and cold-forging a shorn material to forge an oil atomizer pre-forged blank in a revolution shape; (2) putting the oil injector blank into an intermediate frequency furnace for heating with a heating temperature of 800 to 1000 DEG C; (3) putting the heated oil injector pre-forged blank into a die impression with an oil injector cavity, and then finish-forging by a press to forge an asymmetric part on the oil injector; (4) tempering the whole pre-forged blank with a tempering temperature of 520 to 600 DEG C, and then naturally cooling; (5) finally deburring the asymmetric part of the oil injector.

Description

technical field [0001] The invention belongs to the technical field of molding technology, and in particular relates to a molding technology of a fuel injector. Background technique [0002] The forging process of the existing fuel injector generally has two processes: cold forging and hot forging. The internal structure and grains cannot fully meet the performance requirements. Moreover, the blank parts need to be cut and flashed. These cut blanks and flashes cannot be reused, resulting in waste of steel materials. At the same time, they are oxidized at high temperatures. Seriously, the fixture has worn the surface of the mold. Contents of the invention [0003] In order to solve the above-mentioned technical problems existing in the prior art, the present invention provides a molding process of a fuel injector. [0004] The purpose of the present invention is achieved through the following technical solutions: a molding process of a fuel injector, comprising the foll...
