Abstract
The present invention discloses the Forging Technology of a kind of fuel injector nozzle, comprises the following steps: steel biscuit is sent into cold headers by (1), shears, and the blank sheared is carried out cold forging, forges rotational-like nozzle blocking base substrate；(2) nozzle base substrate being put into intermediate frequency furnace to heat, heating-up temperature is 800 1000 DEG C；(3) the nozzle blocking base substrate after heating puts into the impression with nozzle film chamber, then is carried out finish-forging by forcing press, forges the asymmetric part on nozzle；(4) whole blocking base substrate being carried out temper, temperature is 520 600 DEG C, then natural cooling；(5) finally the overlap in part asymmetric to nozzle excises.
Description
Technical field
The invention belongs to technical field of forging, be specifically related to the Forging Technology of a kind of fuel injector nozzle.
Background technology
The nozzle Forging Technology of existing fuel injection equipment typically has cold forging and two kinds of techniques of forge hot, and both technique is each have their own
Feature, cold forging is typically adapted to the Rotary forging of simple shape, and this Forging Technology produce its interior tissue of product and
Crystal grain can not fully meet performance requirement, and, blank needs shearing and deflashing, these blankings cut and overlap the most not
Can be used again, cause the waste of Steel material, the most at high temperature oxidation is serious, the fixture abrasion of die surface.
Summary of the invention
For solving above-mentioned technical problem present in prior art, the invention provides the forging work of a kind of fuel injector nozzle
Skill.
The purpose of the present invention is achieved through the following technical solutions: the Forging Technology of a kind of fuel injector nozzle, including following
Step:
(1) steel biscuit is sent into cold headers, shear, and the blank sheared is carried out cold forging, forge rotational-like
Nozzle blocking base substrate；
(2) nozzle base substrate being put into intermediate frequency furnace to heat, heating-up temperature is 800-1000 DEG C；
(3) the nozzle blocking base substrate after heating puts into the impression with nozzle film chamber, then is carried out finish-forging by forcing press, forges
Asymmetric part on nozzle；
(4) whole blocking base substrate being carried out temper, temperature is 520-600 DEG C, then natural cooling；
(5) finally the overlap in part asymmetric to nozzle excises.
Preferably, in putting into intermediate frequency furnace before heating, antioxidant is coated in nozzle blocking billet surface.
The medicine have the advantages that the present invention is that cold warm forging production line continuous way produces forging, it is to avoid intermediate step
Interrupting, decrease the secondary superficial injury that product causes because manually spreading, cold headers achieve the system of accurate pre-blank simultaneously
Making, be closer to finish-forging die cavity during warm forging molding, so forging overlap is few, more traditional forge hot saves the material cost of nearly 20%；
The temperature using 800-1000 DEG C heats, energy-conserving and environment-protective so that surface scale reduces a lot, and fineness is higher.
Detailed description of the invention
The present invention is described further in conjunction with the embodiments.
The Forging Technology of a kind of fuel injector nozzle, comprises the following steps:
(1) steel biscuit is sent into cold headers, shear, and the blank sheared is carried out cold forging, forge rotational-like
Nozzle blocking base substrate；
(2) nozzle base substrate being put into intermediate frequency furnace to heat, heating-up temperature is 800-1000 DEG C；
(3) the nozzle blocking base substrate after heating puts into the impression with nozzle film chamber, then is carried out finish-forging by forcing press, forges
Asymmetric part on nozzle；
(4) whole blocking base substrate being carried out temper, temperature is 520-600 DEG C, then natural cooling；
(5) finally the overlap in part asymmetric to nozzle excises.
Preferably, in putting into intermediate frequency furnace before heating, antioxidant is coated in nozzle blocking billet surface.
Steel biscuit is sent into cold headers by pulling equipment, by cold headers cutting and that blank carries out multistation successively is cold
Forging, forms the nozzle blocking base substrate of revolving body after cold forging, then passes through tape transport in antioxidant spray coating case, is spraying
Be coated with spraying antioxidant in case, from spraying box out after, then send into through conveyer belt there is film chamber, then carried out finish-forging by forcing press,
Forging the asymmetric part on nozzle, finally the overlap in part asymmetric to nozzle excises.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that still can make
Various modifications and alterations are without departing from the spirit and scope of the present invention.Therefore, description is considered as illustrative rather than limits
Property processed.
