Description
Technical field
The invention belongs to molding technology thereof field, be specifically related to the moulding process of a kind of fuel injector.
Background technology
The Forging Technology of existing fuel injector typically has cold forging and two kinds of techniques of forge hot, each have their own feature of both technique,
Cold forging is typically adapted to the Rotary forging of simple shape, and this Forging Technology produces its interior tissue of product and crystal grain not
Performance requirement can be fully met, and, blank needs shear and deflashing, these blankings cut and overlap all can not be by again
Secondary utilization, causes 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 moulding process of a kind of fuel injector.
The purpose of the present invention is achieved through the following technical solutions: the moulding process of a kind of fuel injector, 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
Fuel injector blocking base substrate；
(2) fuel injector base substrate being put into intermediate frequency furnace to heat, heating-up temperature is 800-1000 DEG C；
(3) the fuel injector blocking base substrate after heating puts into the impression with fuel injector film chamber, then is carried out finish-forging by forcing press, forging
Produce the asymmetric part on fuel injector；
(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 fuel injector excises.
Preferably, in putting into intermediate frequency furnace before heating, antioxidant is coated in fuel injector 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 moulding process of a kind of fuel injector, 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
Fuel injector blocking base substrate；
(2) fuel injector base substrate being put into intermediate frequency furnace to heat, heating-up temperature is 800-1000 DEG C；
(3) the fuel injector blocking base substrate after heating puts into the impression with fuel injector film chamber, then is carried out finish-forging by forcing press, forging
Produce the asymmetric part on fuel injector；
(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 fuel injector excises.
Preferably, in putting into intermediate frequency furnace before heating, antioxidant is coated in fuel injector 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 fuel injector blocking base substrate of revolving body after cold forging, then passes through tape transport in antioxidant spray coating case,
Spraying antioxidant in spraying box, from spraying box out after, then send into through conveyer belt there is film chamber, then carried out end by forcing press
Forging, forges the asymmetric part on fuel injector, and finally the overlap in part asymmetric to fuel injector 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.
Claims (2)
