Abstract
The invention relates to a shell thickness reduction mirror drawing technology, including thickness reduction drawing and saponification treatment. The invention includes the steps as follows: first, the thickness reduction in the first drawing process is 0.4-0.5mm; second, the thickness reduction in the second drawing process is 0.2-0.25mm; third, the thickness reduction in the third drawing process is 0.2mm; fourth, the thickness reduction in the fourth drawing process is 0.10-0.15mm. The saponification treatment is made between every two drawing processes. After the saponification treatment procedures, the thickness reduction is improved; the thickness reduction drawing of the overseas like products needs seven procedures totally; after the saponification treatment is added, the thickness reduction drawing only needs four procedures, drawing fibers are not left on the surface of the work piece and the surface quality of the work piece reaches the demand for mirror; no oil is needed in each drawing process, thus the production efficiency is improved and the production cost is reduced. The invention solves the problem of procedure number and the problem of preventing the surface drawing fibers from reaching the mirror in the existing thickness reduction drawing technology.
Description
Technical field
The invention belongs to the ironing technical field, particularly relate to the above mirror drawing technology of a kind of 1 mm of shell thickness reduction.
Background technology
Require the thin pull and stretch of big thickening for minute surface, no wire drawing trace for the workpiece outer surface, use common process production, the surface does not reach the minute surface level, i.e. surface roughness＞0.2 μ m, and wire drawing is serious, and there is the large tracts of land patch that turns black on the surface.In German production technology, need just can reach requirement with 7 road pull and stretch engineerings.
Summary of the invention
The technical problem to be solved in the present invention provides the above mirror drawing technology of a kind of 1 mm of shell thickness reduction, to solve pull and stretch workpiece surface roughness height in the prior art, the problem of wire drawing situation and ironing engineering number to occur.
The technical solution adopted for the present invention to solve the technical problems is: a kind of shell minute surface ironing technology is provided, and its step comprises: (1) is ironing for the first time; (2) ironing for the second time; (3) ironing for the third time; (4) the 4th ironings, described each time ironing comprise saponification processing engineering.
Described pull and stretch attenuation first time amount is 0.4 ~ 0.5mm; The amount of pull and stretch attenuation for the second time is 0.2 ~ 0.25mm; The amount of pull and stretch attenuation for the third time is 0.2mm; The 4th time pull and stretch attenuation amount is 0.10 ~ 0.15mm.
Principle analysis: because drawing depth is dark, the attenuation amount is big, in the drawing process, degree of depth friction produces high heat (surperficial instantaneous temperature reaches more than 110 ℃), and at high temperature, oil is burnt the back and knot carbon occurs, the carbon compound forms surface of the work large tracts of land blackout attached on the surface of the work; Carbon formation layer sticks on the mold cavity, the serious wire drawing when causing pull and stretch.
Before and after each pull and stretch, increase saponification and handle, through this processing, deliquescing of workpiece material top layer and formation saponification film, therefore, during pull and stretch, coefficient of friction significantly reduces, and surface of the work reaches minute surface, and the wire drawing phenomenon disappears thereupon.
Beneficial effect
After increasing the saponification treatment process, pull and stretch attenuation amount improves greatly, and number of drawing significantly reduces.After increasing the saponification treatment process, the surface of the work minute surface has reached requirement, and workpiece quality improves greatly; And, in each road drawing process, not needing to refuel again, production efficiency improves, and production cost reduces.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only are used for scope of the present invention.Should be understood that in addition those skilled in the art can do various references or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
Workpiece material thickness 4.0mm, external diameter Φ 102.2 ± 0.10mm, internal diameter are φ 96.35 ± 0.10mm, and the attenuation amount is 1.07mm, and workpiece height 87mm requires surface of the work to arrive minute surface (roughness 0.2 μ m is following), no wire drawing vestige.
Use a kind of shell attenuation mirror drawing technology, its step comprises: (1) is ironing for the first time; (2) ironing for the second time; (3) ironing for the third time; (4) the 4th ironings, described each time ironing comprise saponification processing engineering.
Claims (2)
1. a shell attenuation mirror drawing technology comprises ironing and saponification processing, and it is characterized in that: comprise step: (1) is ironing for the first time; (2) ironing for the second time; (3) ironing for the third time; (4) the 4th ironings, described each time ironing comprise saponification processing engineering.
2. a kind of shell attenuation mirror drawing technology according to claim 1 is characterized in that: described pull and stretch attenuation first time amount is 0.4 ~ 0.5mm; The amount of pull and stretch attenuation for the second time is 0.2 ~ 0.25mm; The amount of pull and stretch attenuation for the third time is 0.2mm; The 4th time pull and stretch attenuation amount is 0.10 ~ 0.15mm.
