Description
Technical field
The invention belongs to materials science field, be specifically related to preparing material and utilizing this material to prepare the method for cylinder sleeve tooling base of a kind of cylinder sleeve tooling base.
Background technology
Cylinder sleeve is one of key components and parts of engine, and its material mostly is alloy gray cast-iron at present, is organized as perlite or bainite.When the cylinder sleeve of processing particular requirement, the tooling base Chang Wufa of prior art satisfies production requirement.For example at a kind of tempered martensite that is organized as of processing, internal surface is through high-frequency quenching, quenched case is 0.8-1.2mm and when the quenched case deviation can not surpass the cylinder sleeve of 0.254mm up and down, gross distortion very easily occurs in tooling base endoporus and excircle dimension, cause interior surface of cylinder liner quenched case out-of-size, can't satisfy production requirement.Therefore developing a kind of on-deformable cylinder sleeve tooling base material is of great significance with regard to tool.
Summary of the invention
The object of the invention is to provide a kind of stable performance, on-deformable cylinder sleeve tooling base material and utilizes this material to prepare the method for cylinder sleeve tooling base.
Technical solution of the present invention is as follows.
A kind of cylinder sleeve tooling base prepares material, and this material belongs to austenitic iron, and by mass percentage, each forms content and is: C, 2.75% ~ 3.0%; Si, 1.8% ~ 2.3%; P,＜0.08%; S,＜0.1%; Mn, 14% ~ 16%; Nb, 0.04% ~ 0.06%; Rare earth, 0.04% ~ 0.08%; Surplus is iron.
Described cylinder sleeve work base prepares material, and by mass percentage, each forms content and is: C, 2.85%; Si, 1.85%; P, 0.043%; S, 0.065%; Mn, 14.5%; Nb, 0.055%; Rare earth, 0.075; Surplus is iron.
Described cylinder sleeve work base prepares material, and by mass percentage, each forms content and is: C, 2.95%; Si, 1.95%; P, 0.06%; S, 0.058%; Mn, 15.3%; Nb, 0.045%; Rare earth, 0.065; Surplus is iron.
A kind of preparation method of cylinder sleeve work base may further comprise the steps:
(1) each component is prepared burden by following mass percent: C, 2.75% ~ 3.0%; Si, 1.8% ~ 2.3%; P,＜0.08%; S,＜0.1%; Mn, 14% ~ 16%; Nb, 0.04% ~ 0.06%; Rare earth, 0.04% ~ 0.08%; Surplus is iron;
(2) step (1) gained batching smelting and pouring is become cast tube;
(3) cast tube is processed as base, and inside and outside wall stays the 0.6mm surplus;
(4) base is sent into neutral stove in 1050 ~ 1100 ℃ of lower insulation 50 ~ 60min; Then the rear fan blast-cold of using of coming out of the stove;
(5) the complete rear endoporus of machining carries out laser grooving, and with the frictional force of the gentle outer wall of cylinder jachet of increase endoporus, thereby cylinder sleeve does not rotate in frock when guaranteeing high-frequency quenching.
Need to prove that rare earth that the present invention adopts is a kind of commercially available prod, its component content is: Re:30 ~ 33%, and Si:40%, Mn, 3.0%, Ca, 4.0%, Ti:1.0%, surplus is Fe..
Cylinder sleeve tooling base material provided by the present invention belongs to a kind of austenitic iron, and compared to the tooling base material of prior art, the increase of Mn element ratio has enlarged austenite region, and the austenitic transformation point is down to below the room temperature; The rare earth rare earth elements is so that grain refining; And the interpolation of Nb element has improved near the hardening capacity of laser time slot.
Among the preparation method of tooling base provided by the present invention, make organizer carry out austenite by the neutral atmosphere heating steps first and transform, then carry out solution treatment by air-cooled, obtain to be organized as austenitic cast iron materials.Because austenite is a kind of paramagnetism structure, so when high frequency treatment is regulated the flow of vital energy cylinder sleeve, do not produce electromotive force inside and outside the base, dimensional stabilizing, make groove generation on every side high dislocatrion martensite increase as thin as a wafer and the frictional force of cylinder sleeve by endoporus laser at last, make this material highlight the superiority of its dimensional stabilizing, when the cylinder sleeve of preparation particular requirement, the HBW index of tooling base can reach 130 ~ 160, tensile strength can reach 170 ~ 210Mpa, through using product cylinder sleeve bore quenched case deviation to be no more than 0.15mm, result of use is good, has realized preferably goal of the invention.
Embodiment
Below in conjunction with embodiment the present invention will be further explained explanation.
The rare earth source that following embodiment adopts for a kind of trade mark that casting peak, Ningxia specific alloy company limited produces is: FeSiRe32-B product, and its Contents of Main Components is: Re:30 ~ 33%, Si:40%, Mn, 3.0%, Ca, 4.0%, Ti:1.0%, surplus is Fe..
