Abstract
The invention relates to an elastic retainer ring processing method. A blanking piece process is adopted for an elastic retainer ring with the thickness being more than or equal to 3.5mm, and the shape of the blanking piece of the elastic retainer ring during an intermediate process of blanking is improved. The method comprises the following steps that (1) residual materials which are machined at the opening of the elastic retainer ring are added, and the blanking process property of the elastic retainer ring is improved; and a method of first blanking with a blanking mold and then positioning with blanking appearance is adopted; (2) a mold structure design method is adopted, the mold blanking spacing is regulated to be small, the quality of the elastic retainer ring is improved, the service life of the blanking mold is prolonged, the assembly symmetry between a positioning plate in a punching mold of the elastic retainer ring and a convex mold as well as between the positioning plate and a concave mold is regulated, so that single-side products are avoided during a mold blanking process; and (3) the residual materials of the blanking piece are removed by machining. The method relates to the blanking piece process property and the mold structure design method, has a novel and simple structure, and can meet the blanking and the formation of the elastic retainer ring with the thickness being more than or equal to 3.5mm.
Description
Technical field
The present invention relates to a kind of circlip processing method.
Background technology
At present, the circlip of material thickness 〉=3.5 ㎜, because the restriction of part material, shape, size, and the restriction of dimensional accuracy, the common stamping difficulty reaches the Element Design requirement, usually adopts the line cutting processing to be shaped.Because the circlip material of material thickness 〉=3.5 ㎜ is 65Mn, dimension precision requirement is high, inside and outside circle is eccentric, and the difference a of the inside and outside circle radius＜reasons such as material thickness t, conventional punching process method is adopted in processing, the stamping-out defectives such as crackle, burr, monolateral, distortion very easily appear in product, and cause die life short; If adopt the line cutting forming, production efficiency is low, production cost is higher.
Therefore, need efficient, a high-quality technological method for processing to finish the circlip processing that is shaped.
Summary of the invention
For addressing the above problem, the present invention adopts the blanking part manufacturability of circlip is carried out architecture advances, and the mould structure method for designing is rationally adjusted.
This circlip processing method comprises:
1, increases circlip opening part machine and add clout, improve the punching process of circlip; Adopt and use first the blanking die blanking, the method for recycling blanking profile location;
2, mould structure method for designing, blade clearance to the circlip blanking die of thickness 〉=3.5 ㎜ is defined as little gap, stamping-out cutting edge double-faced clearance is 0.3 ㎜ ∽, 1 ㎜, improve circlip quality and blanking die life-span, location-plate and punch and matrix assembling symmetry in the punching die of circlip is stipulated, the monolateral phenomenon of product in the Dies ' Blanking process has been avoided in symmetry≤0.03;
3, machine adds the blanking part clout.
The invention provides a kind of circlip processing method, relate to a kind of blanking part manufacturability, the mould structure method for designing, novel structure, simple and easy can satisfy the circlip Blanking Shaping of material thickness 〉=3.5 ㎜.Blanking part technologic structure of the present invention and mentality of designing can be as slab Blanking Shaping typical cases, edify the professional and make and a series ofly quote and extend.
Description of drawings
Fig. 1 is part drawing,
Fig. 2 is part punching process figure.
The specific embodiment
A kind of circlip processing method comprises: the circlip to material thickness 〉=3.5 ㎜ adopts blanking part technique, and the circlip blanking part shape in the punching out pilot process is improved, and takes to utilize again hole punching technological process of mould elder generation blanking; To the mould structure method for designing, blanking die and punching die blade clearance are stipulated; It is fixed that counter-punching die tool location-plate and punch and matrix fit into professional etiquette.
Concrete grammar comprises:
1, increases circlip opening part machine and add clout, improve the punching process of circlip; Adopt and use first the blanking die blanking, the method for recycling blanking profile location;
2, mould structure method for designing, the Dies ' Blanking clearance gauge is decided to be little gap, improve circlip quality and blanking die life-span, location-plate and punch and matrix assembling symmetry in the punching die of circlip is stipulated, avoided the monolateral phenomenon of product in the Dies ' Blanking process;
3, machine adds the blanking part clout.
As seen from Figure 1: because the circlip material of material thickness 〉=3.5 ㎜ is 65Mn, dimension precision requirement is high, inside and outside circle is eccentric, and the difference a of the radius＜reasons such as material thickness t adopts conventional Blanking Shaping technique, and crackle, burr, the stamping-out defective such as monolateral, dish-shaped very easily appear in product, in the circlip of material thickness 〉=3.5 ㎜ is produced, because profile is the method for commonly using in the restriction of part material, shape, size, and the restriction of dimensional accuracy, line cutting processing circlip.As seen from Figure 2: profile adopts Dies ' Blanking to be shaped in the circlip, and the blanking part manufacturability of the circlip of material thickness 〉=3.5 ㎜ is improved, and adds the machine that very much not affects following process and adds clout; The circlip inside and outside circle is eccentric, if adopt blanking, punching composite die construction design method, causes the mould pressure-plate-force larger, and mould convexity Die Design is comparatively thin, and die point intensity is low, causes the unfavorable factors such as die life weak point.Take the again mould structure method for designing of punching technology of first blanking, the Dies ' Blanking gap is rationally adjusted; Because the circlip inside and outside circle of material thickness 〉=3.5 ㎜ is eccentric, product very easily occurs monolaterally in the stamping-out process, and mould location-plate and the requirement of punch and matrix assembling symmetry are stipulated.
Process structure of the present invention is novel, simple and easy, can realize the circlip Blanking Shaping of material thickness 〉=3.5 ㎜.This circlip processing method, production efficiency is high, and the product cost that processes is low, and interchangeability is good.
