Description

A kind of high-strength corrosion-resisting spring machining process
Technical field
The invention discloses a kind of high-strength corrosion-resisting spring machining process.
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 corrosion-resisting spring, its feature exist In：The mass percent of each composition is in the high-strength spring：C：1.6%, Al：2.2%, Mg：0.15%, Y：1.08%, Zr：0.21%, Sn：0.25%, Zn：0.12%, Si：0.23%, Mn：0.25%, S：0.14%, P：0.1%, Cr：0.23%, Ni：1.25%, V：0.12%, Mo：0.5%, Ti：0.35%, B：0.3%, Pd：0.1%, W：0.12%, Ta：0.23%, Nd： 1.2%, Ce：0.44%, Lu：0.84%, 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) hot rolling：Spring wire after tagging is heated to 1000 DEG C, peace carries out heat according to predetermined height, external diameter and the number of turns Volume, soaking time are 100 minutes；
(iii) tagging：The two ends of spring wire are transitioned into square-section from circular section using the mode forged；
(iv) flaw detection is handled；
(v) swirling flows：Spring is depressed into requirement height, 15-30h is parked, then decontrols；
(vi) Shot Blasting：Spring is subjected at least 3 Shot Blastings；
(vii) it is heat-treated：Using the Technology for Heating Processing of quenching-heating-tempering；
(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
Specific embodiment：A kind of high-strength corrosion-resisting spring, it is characterised in that：The matter of each composition in the high-strength spring Measuring percentage is：C：1.6%, Al：2.2%, Mg：0.15%, Y：1.08%, Zr：0.21%, Sn：0.25%, Zn：0.12%, Si：0.23%, Mn：0.25%, S：0.14%, P：0.1%, Cr：0.23%, Ni：1.25%, V：0.12%, Mo：0.5%, Ti：0.35%, B：0.3%, Pd：0.1%, W：0.12%, Ta：0.23%, Nd：1.2%, Ce：0.44%, Lu：0.84%, it is remaining Measure as 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：
