Abstract
The invention relates to a machining process of an ultra-long cylindrical thin-wall part. The particular machining steps include that 1, rod materials are machined into single blank materials according to the needed length size, and 10 mm of margin is reserved; 2, a large lathe is used, the two ends of the single blank materials are flattened to the length size; the outer circle is roughly turned, and 1 mm of margin is reserved for the outer circle to the size; 3, punching is carried out, an inner hole is machined through a deep hole drill to the size requirements, and the inner stress is eliminated; 4, a self-manufactured core rod phi 28 0-0.01 is put into a phi 28 inner hole, and the two ends are fixed, the self-manufactured core rod is arranged on the large lathe, the two ends of the self-manufactured core rod are ejected through ejection pins, the outer circle is turned in a fine mode, the inner stress generated in the outer circle fine turning process is eliminated to the wall thickness size, and finally the self-manufactured core rod is detected and put into a warehouse. The machining process is specially used for machining the ultra-long cylindrical thin-wall part and practiced multiple times by production enterprises. More importantly, the deep hole drill is used for machining the inner hole, the coaxiality of the whole inner hole and the outer circle is guaranteed, the inner stress is eliminated, and products are prevented from cracking and deforming.
Description
Technical field
The invention belongs to field of machining, particularly a kind of processing technology of overlength cylindrical shape thin-walled parts.
Background technology
At mechanical processing industry, the processing of cylindrical shape thin-walled parts is a processing difficult problem always.Although technique should be very simple in the imagination, only to need on lathe planar end surface, turning, punching just, but the part processed is exactly defective, reason is because part wall is thin, add the easy deformation processing of part in man-hour not out, the instructions for use of product can not be met.If thin-walled parts adds longer dimension, processing is just more difficult.
Summary of the invention
The object of this invention is to provide a kind of processing technology that can ensure overlength cylindrical shape thin-walled parts technical requirement.
A processing technology for overlength cylindrical shape thin-walled parts, its concrete procedure of processing is:
(1) bar being dimensioned to length by Len req is 1010 ㎜ single-piece blanks;
(2) upper large-scale lathe, two ends planar end surface is to length dimension; Rough turn cylindrical, cylindrical stays 1 ㎜ surplus to size;
(3) punch, adopt depth drill processing endoporus to dimensional requirement and eliminate internal stress;
(4) self-control plug φ 28 is adopted
0 -0.01put into φ 28 endoporus, two ends are fixed; Upper large-scale lathe two ends thimble withstands, and fine turning outer circle is to wall thickness dimension, and punching rod can ensure the axiality requirement of endoporus and cylindrical;
(5) examination and test of products; Check by product technology requirement;
(6) product that will be up to the standards is put into special purpose device and is put in storage.
Processing technology of the present invention be repeatedly putting into practice of passing through of manufacturing enterprise draw a kind of specially for the processing method of overlength cylindrical shape thin-walled parts, main is adopt depth drill to carry out endoporus processing, the axiality of whole endoporus can be ensured, turn eliminate internal stress, prevent product from drawing up and be out of shape.Substantially increase the qualification rate of product, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of overlength cylindrical shape thin-walled parts exemplar of the present invention.
Detailed description of the invention
Be that exemplar describes in detail the present invention below with Fig. 1.
The method of tradition processing cylindrical shape thin-walled parts be use numerically controlled lathe to carry out holing, half right boring and right boring hole, thick, fine turning outer circle is processed.But for the clavate material that wall is thin, cylindrical, hole size instability and axial cylindrical and endoporus will be caused so easily to produce the phenomenons such as tapering, make product rejection rate very high.
The object of the invention is to overcome the deficiencies in the prior art, ensure completing of overlength cylindrical shape thin-walled parts processing by this programme.As shown in Figure 1, the length of this part is 1000 ㎜ ± 0.02mm, and excircle dimension is 29.7 ㎜ ± 0.02mm, and hole size is 28 ㎜ ± 0.01mm, and wall thickness is 0.85 ㎜, requires that axiality is 0.01.The difficult problem that this part adds man-hour is part overlength, and wall thickness is thinner, and will ensure axiality requirement.
A processing technology for overlength cylindrical shape thin-walled parts, its concrete steps are:
(1) bar being dimensioned to length by Len req is 1010 ㎜ single-piece blanks;
(2) upper large-scale lathe, two ends planar end surface is to length dimension; Rough turn cylindrical, cylindrical stays 1 ㎜ surplus to size;
(3) punch, adopt depth drill processing endoporus to dimensional requirement and eliminate internal stress;
(4) self-control plug φ 28 is adopted
0 -0.01put into φ 28 endoporus, two ends are fixed; Upper large-scale lathe two ends thimble withstands, and by technological requirement fine turning outer circle to wall thickness dimension, eliminates internal stress; Punching rod can ensure the axiality of endoporus and cylindrical;
(5) examination and test of products; Check by product technology requirement;
(6) product that will be up to the standards is put into special purpose device and is put in storage.
The present invention is by repeatedly putting into practice the processing solving a kind of overlength cylindrical shape thin-walled parts.Further ensure carrying out smoothly of ultralong thin walled part processing, thus made product percent of pass bring up to more than 98%, greatly reduce production cost.
