Abstract

The invention relates to a processing process of a thin-wall part. The process specifically comprises the steps of blanking, namely, cutting a part into single pieces; clamping the left end of the part cut into single pieces; roughly turning the outer round single edge margin; drilling a hole until reaching the dimension required, and maintaining margin for expanding and hinging the hole; ensuring the requirement on the surface roughness; removing burrs from an acute angle; turning around the part; roughly turning an outer round, cutting a slot, and performing half finished turning for the outer round margin; ensuring the requirement on the surface roughness; removing burrs from the acute angle; performing finished turning for an inner hole and the outer round until meeting the dimension requirement; ensuring the requirement on the surface roughness; removing burrs from the acute angle; inserting a small-taper mandrel; performing finished turning for the outer round until meeting the dimension requirement; ensuring the requirement on the surface roughness; removing burrs from the acute angle. According to the processing process of the thin-wall part, the processing line of the thin-wall part is improved, the novel process method is analyzed and applied, and therefore, the product quality is greatly improved, the rejection rate is reduced, and the production rate and economic benefit are increased.

Description

A kind of processing technology of thin-walled parts
Technical field
The invention belongs to mechanical manufacturing field, particularly a kind of processing technology of thin-walled parts.
Background technology
GH4169 alloy strengthening effect is good, and alloying level is high, and heat endurance and calorific intensity are all higher, under 980 ° of C, there is good antioxygenic property, have splendid creep rupture strength at 700 ° of these alloys of below C, under 650 ° of C, yield strength is high, plasticity is good, good moldability, has good weldability and high-temperature oxidation resistance etc., because of its function admirable, in the design of aircraft, rocket, guided missile, especially often use in the manufacture of aero-engine, rocket engine.But, in machined, in GH4169 the element such as molybdenum, titanium, niobium cutter is is very easily worn and torn, damaged, in machined, easily produce built-up edge, nickel, chromium element make chip not easily disconnect, and cutter heat radiation is not smooth, workpiece easily scratches, and has a strong impact on surface quality, reduces productivity ratio, increase production cost, thermal conductivity is low, and work hardening is serious, and during cutting, phenomenon bonding with cutter is serious, chip is very difficult, and scrappage is very high.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of minimizing scrappage, improve the processing technology of a kind of thin-walled parts of productivity ratio and economic benefit.
A processing technology for thin-walled parts, its concrete procedure of processing is:
(1), blanking: part is cut into single-piece;
(2), the part left end cutting into single-piece is clamped, the monolateral made allowance of rough turn cylindrical;
(3), be bored into size, leave surplus and carry out reaming, fraising; Ensure surface roughness requirements; Acute angle deburring;
(4), part tune; Rough turn cylindrical, grooving, half fine turning outer circle made allowance; And ensure surface roughness requirements; Acute angle deburring;
(5) finish turning endoporus and cylindrical are to dimensional requirement, ensure surface roughness requirements; Acute angle deburring;
(6), wear Small Taper mandrel, fine turning outer circle to dimensional requirement, and ensures surface roughness requirements; Acute angle deburring.
The processing technology of a kind of thin-walled parts of the present invention is passed through the improvement of this thin-walled parts processing route and the analysis and application of new process, significantly improve product quality, decrease scrappage, improve productivity ratio and economic benefit, more deep understanding is processed with to high temperature alloy, for the processing of other high temperature alloys in the future have accumulated certain experience.
Accompanying drawing explanation
Fig. 1 is the structural representation of exemplar of the present invention.
Detailed description of the invention
For the processing of thin-walled parts cylindrical, because part wall is thin, there is no suitable clamping position, clamping difficulty.For this type of thin wall component, the easily distortion of three-jaw folder, if take endoporus or excircle orientation, employing end face compresses, and thrust direction is consistent with processing cutting direction, can reduce clamping and machining deformation, but for this part, minimum wall thickness (MINI W.) 0.16mm, obvious end face compressing method is unworkable; This External Shape itself is also uncomplicated, and difficult point is that material cutting ability is bad, and extremely difficult processing, has reformulated the process program of this type of part of processing finally by the on-the-spot processing situation of further investigated analysis and extensive inspection information.
Fig. 1 is the structural representation of exemplar of the present invention.
A processing technology for thin-walled parts, its concrete procedure of processing is:
(1), blanking: part is cut into single-piece;
(2), the part left end cutting into single-piece is clamped, the monolateral made allowance of rough turn cylindrical;
(3), be bored into size, leave surplus and carry out reaming, fraising; Ensure surface roughness requirements; Acute angle deburring;
(4), part tune; Rough turn cylindrical, grooving, half fine turning outer circle made allowance; And ensure surface roughness requirements; Acute angle deburring;
(5) finish turning endoporus and cylindrical are to dimensional requirement, ensure surface roughness requirements; Acute angle deburring;
(6), wear Small Taper mandrel, fine turning outer circle to dimensional requirement, and ensures surface roughness requirements; Acute angle deburring.
Drill bit of the present invention has made corresponding requirements: the length as far as possible shortening drill bit, and strengthens unbearabling thickness, suitably increases drill bit back taper, increases drill head apical angle, increases drift angle and namely increases the intensity of apex point and be convenient to heat radiation, also increase the anterior angle of drill lip simultaneously.
Tool geometrical parameter of the present invention requires:
A: the blade of cutter should remain sharp, anterior angle should be on the occasion of, but can not be excessive, relief angle generally should be slightly larger, ensures its requirement of strength;
B: the content of cutting data is generally low cutting speed, larger back engagement of the cutting edge, and blade is cut all the time below chilling layer;
C: suitable cutting fluid should be selected, otherwise stress corrosion can be caused to workpiece, affect the fatigue strength of part.
The processing technology of a kind of thin-walled parts of the present invention is passed through the improvement of this thin-walled parts processing route and the analysis and application of new process, significantly improve product quality, decrease scrappage, improve productivity ratio and economic benefit, more deep understanding is processed with to high temperature alloy, for the processing of other high temperature alloys in the future have accumulated certain experience.
