Abstract

The invention discloses a method for processing ultrathin-wall parts, which comprises the following steps: 1) forging conjoined forge pieces; 2) lathing the inside and outside diameters and end faces of the conjoined forge pieces; 3) carrying out heat treatment; and 4) carrying out processing and separation, namely polishing two end faces, outside diameters, inside diameters, channels and superfine channels of the conjoined forge pieces, and separating the conjoined forge pieces. The method has the following advantages that: because the method for processing two or more conjoined parts is adopted, the rigidities of the ultrathin-wall parts which are easy to deform in the past are increased; no matter lathing or heat treatment, the parts are not easy to deform; and the method can adopt common processing modes and common equipment, use common technical personnel to perform operation, and improve the yield. Moreover, by processing the two or more conjoined parts, the allowance of blanks can be reduced to be very small so as to save raw materials during charging. In conclusion, the method reduces the cost, improves the production efficiency, and greatly improves the product percent ofpass.

Description

A kind of method of processing ultrathin-wall parts

Technical field

The present invention relates to precision optical machinery and make field, particularly a kind of method of processing ultrathin-wall parts.

Background technology

The processing of existing ultra-thin wall parts, basically adopt the method for single-piece work, be divided into metal working processing (comprising Vehicle Processing, mill processing) and heat treatment process, step is: 1, car mill processing: add man-hour in order to prevent the distortion of work piece, usually adopt special precision anchor clamps, blank to strengthen allowance, select high-level technical staff measure such as processing meticulously slowly for use, to reduce the distortion of work piece, improve product percent of pass; 2, heat treatment: ultra-thin wall parts heat treatment is very difficult, because the special easy deformation of ultra-thin wall parts so adopt single-piece fixation (interior support), strengthens the parts allowance and adopts vacuum heat treatment furnace etc.There is very big defective in said method: 1, car mill single-piece work is because parts are too thin, and machining deformation is big, and work is difficulty very; Because of the blank allowance is big, generally want more than the 0.6-1MM again, so many allowance obviously makes mill several times process time ground prolong, and processes very time-consumingly, and percent defective is very high; Moreover high-level technical staff is very rare, and the personnel selection cost is huge.2, the heat treatment of ultra-thin wall parts must be adopted high-grade heat treatment stove, not only increases cost greatly, and great limitation is arranged.

In a word, prior art adopts the method for single-piece work to ultra-thin wall parts, not only wastes time and energy, and inefficiency, and the means of taking for the problem on deformation of control work piece are still very limited has improperly will produce a large amount of wasters slightly.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of can add the method that is not easy to be out of shape, not need a lot of allowances, cost is low, efficient is high processing ultrathin-wall parts man-hour at above-mentioned prior art present situation.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of method of processing ultrathin-wall parts, it is characterized in that: comprise the steps: 1) make the disjunctor forging: calculate the overall size of several forging of disjunctor and finish turning surplus, the allowance at disjunctor forging two ends, the slot when each forging separates, add the overall width that together draws the disjunctor forging; 2) external diameter, end face in the above-mentioned disjunctor forging are machined: 3) quenching heat treatment: 4) processing, separation: mill disjunctor forging both ends of the surface → external diameter → internal diameter → raceway groove → super smart raceway groove → separation.

Described step 2) in, will process separating tank between each forging in the disjunctor forging; In the described step 4), with separation place reprocessing end face, the chamfering of each forging after separating; Described several forging can for two and more than.

Compared with prior art, the invention has the advantages that, because the present invention is owing to adopted the part disjunctor processing method more than two and two, make the original very easily ultrathin-wall parts of distortion increase rigidity, no matter be processing of car mill or heat treatment, parts are not yielding, both can adopt the common process mode and adopt common equipment, use general technical staff to operate, can improve output again.Moreover, the part disjunctor processing more than two and two, it is very little that the blank allowance also can reduce to, thereby just saved raw material when feeding intake.In a word, the present invention had both reduced cost, had improved its production efficiency again, had increased substantially product percent of pass.

The specific embodiment

Below in conjunction with embodiment the present invention is described in further detail.

A kind of method of processing ultrathin-wall parts, comprise the steps: 1) make the disjunctor forging: calculate the overall size of several forging of disjunctor and finish turning surplus, the allowance at disjunctor forging two ends, the slot when each forging separates, add the overall width that together draws the disjunctor forging; 2) external diameter, end face in the above-mentioned disjunctor forging are machined: 3) quenching heat treatment: 4) processing, separation: mill disjunctor forging both ends of the surface → external diameter → internal diameter → raceway groove → super smart raceway groove → separation; 5) assembling.

Several forging described in the described step 1) can for two and more than; Described step 2) in, will process separating tank between each forging in the disjunctor forging, groove width is promptly pressed the width of cutting blade, and groove depth makes the disjunctor forging keep rigidity to get final product; In the described step 4), with separation place reprocessing end face, the chamfering of each forging after separating.

With the width that manufactures a finished product is that the bearing ring of 5MM is an example:

In the prior art, make forging by the bearing round steel: a finished width 5MM+ forging allowance 4MM=9MM is 4 as forging quantity, and then overall width is: 9MM * 4=36MM;

Among the present invention, disjunctor processing, a finished width 5MM+ finish turning surplus 0.5MM=5.5MM is 4 as forging quantity, the allowance at disjunctor forging two ends is that 4MM, the slot when each forging separates are 1.6MM * 3=4.8MM, and then overall width is: 5.5MM * 4+4MM+4.8MM=30.8MM;

Through above-mentioned analysis as can be seen, the processing of per 4 parts just can be saved the 5MM material.

External diameter and end face machines, quenching heat treatment, process when operation such as separating in above-mentioned disjunctor forging is carried out because the disjunctor forging rigidity among the present invention is strong, allowance is few, have with respect to single-piece work not yielding, car, mill processing easily.

Forging after each is separated grinds and adds man-hour at last, because the nearly 0.6---1MM of the allowance of forging in the prior art, and the allowance of forging has only 0.2MM among the present invention, the former will spend more expense and be several times as much as the amount of labour used of the present invention.

Claims
