Description

High-strength spring processing technology
Technical field
The invention discloses a kind of high-strength spring and its processing technology.
Background technology
Spring is a kind of widely used flexible member, and shape occurs under external force for part made of elastomeric material Become, restored to the original state again after removing external force, its profile is mostly cylinder, and production and processing can be divided into cold coiling shaping and hot rolling shaping, also Make " spring ".Spring in order to its assembly space preferably coincide, be also designed as it is non-cylindrical, such as automobile dual-mass flywheel Spring is arc spring.The species complexity of spring is various, by shape point, mainly there is helical spring, scroll spring, plate bullet Spring, heterotypic spring etc..
Spring is very universal in present application, all trades and professions according to different purposes using varying strength rigidity and The spring of service life.Existing spring strength is low, and service life is short, and easy rust corrosion.
The content of the invention
The technical solution adopted for the present invention to solve the technical problems is：A kind of high-strength spring, it is characterised in that：It is described The mass percent of each composition is in high-strength spring：C：2%, Al：1.2%, Mg：0.15%, Y：0.25%, Zr：0.27%, Sn：0.21%, Zn：0.12%, Si：0.23%, Mn：0.25%, S：0.14%, P：1%, Ni：1.25%, Cu：0.5%, V： 0.12%, Mo：0.5%, Ti：0.6%, B：0.1%, Pd：0.1%, Pt：1.2%, W：0.12%, Ta：0.23%, Nd： 1.2%, Ce：0.44%, Lu：1.13%, surplus Fe.
An object of the present invention also resides in the processing technology for providing high-strength spring of the present invention, including following step Suddenly：
(i) blanking：Gas cutting raw material determines length, reconditioning cut surface；
(ii) tagging：The two ends of spring wire are transitioned into square-section from circular section using the mode forged；
(iii) hot rolling：Spring wire after tagging is heated to 1200 DEG C, peace carries out heat according to predetermined height, external diameter and the number of turns Volume, soaking time are 100 minutes；
(iv) it is heat-treated：Using the Technology for Heating Processing of quenching-heating-tempering；
(v) Shot Blasting：Spring is subjected at least 3 Shot Blastings；
(vi) flaw detection is handled；
(vii) swirling flows：Spring is depressed into requirement height, 14h is parked, then decontrols；
(viii) electroplate：In spring surface by zinc plating, thickness of coating is 10-12 microns.
The beneficial effects of the invention are as follows：(1) high-strength spring of the invention elasticity is big, corrosion resistance and good, service life It is long；(2) by the processing technology of high-strength spring of the invention, Technology for Heating Processing particularly therein, it can control spring horizontal With it is longitudinally concave caused by face crack, and spring silk table surface layer can be made to produce the residual stress opposite with working stress, during stand under load Part working stress can be offset, increases service life.
Embodiment
