Abstract
The invention aims to provide a small flange tubular part non-thinning drawing process. The process includes the following steps that material softening, washing and lubricating are conducted on a blank; the processed blank is placed in a drawing die for four times of drawing; trimming deflashing is conducted; shape correcting is conducted. Final finished products are acquired through the four times of drawing, a series of earlier stage processing of softening, washing and lubricating is conducted before drawing, and then the number of drawing times is reduced, efficiency is improved, materials are softened and lubricated in the drawing process, and then the drawing efficiency can be further improved. The small flange tubular part non-thinning drawing process is easy to operate and suitable for production.
Description
Technical field
The present invention relates to deep-drawing technique field; Relate in particular to a kind of little not attenuation of flange cylindrical member deep-drawing technique.
Background technology
Drawing is exactly in fact the flange portion material of hair Pei to be transferred to gradually to the process of barrel, in the process shifting, the material of flange is owing to being subject to the effect of drawing pressure, radially produce draw should in, because flange portion diameter diminishes gradually, between flange portion material, produce squeezing action, in the tangential compression that produces, under the acting in conjunction of tension and compression, the metal of flange portion produces plastic deformation, radial extent, tangentially compression, size reduction, and be constantly drawn into the hollow element that becomes tubular in die hole.Deep-drawing technique is widely used in automobile making, electronic apparatus and daily living article, very important, and current not meticulous for producing the processing step of little flange cylindrical member in the production of my company, the product quality of drawing does not pass a test, and one of therefore optimizes technique and just seems very necessary.
Summary of the invention
The invention provides a kind of little not attenuation of flange cylindrical member deep-drawing technique, adopt four times drawing, and before drawing, have process a series of early stages, and the softening and lubricated of also following in drawing process solves the problem occurring in background technology.
The object of this invention is to provide a kind of little not attenuation of flange cylindrical member deep-drawing technique, comprise the following steps:
Step 1: the blank of required drawing is carried out to the thermoplastic processing of material;
Step 2: the blank of step 1 gained is washed with specific acid solution;
Step 3: the lubricating oil of appointment is embrocated on the surface of the blank to step 2 gained;
Step 4: the blank of step 3 gained is put into Drawing Die and carry out blanking and drawing, start to form the shape of required drawing part;
Step 5: the blank of step 4 gained is carried out to drawing again, further increase the drawing part degree of depth, make the shape of blank more close to drawing part;
Step 6: the drawing part of step 5 gained is carried out to drawing again, increase again the drawing part degree of depth, make the shape of blank basic identical with drawing part;
Step 7: the drawing part of step 6 gained is carried out to drawing again, increase again the drawing part degree of depth, make the shape of blank be equal to drawing part;
Step 8: the semi-finished product of step 7 gained are carried out to deburring processing;
Step 9: the semi-finished product of step 8 gained are carried out to Shape correction, obtain finished product.
Further improve and be: described step 4 and five, step 5 and six, is accompanied by the thermoplastic processing to blank between step 6 and seven, embrocate if desired the lubricating oil of appointment after softening processing.
Further improve and be: described step 4, five, six and seven need be embrocated the lubricating oil of appointment before drawing in Drawing Die with blank contact position.
Further improve and be: increase the degree of depth of blank thereby described step 4, five, six and seven drawing are the sizes of dwindling mao accessory bottom surface.
Beneficial effect of the present invention: by adopting four drawing to become final finished product, and before drawing, have process a series of early stages: softening, cleaning and lubricated, number of drawing is reduced, efficiency improves, and the softening and lubricated to material of also following in drawing process, further can make efficiency of drawing improve, whole invention is simple to operation, in being applicable to produce.
The specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
The present embodiment provides a kind of little not attenuation of flange cylindrical member deep-drawing technique, comprises the following steps:
Step 1: the blank of required drawing is carried out to the thermoplastic processing of material;
Step 2: the blank of step 1 gained is washed with specific acid solution;
Step 3: the lubricating oil of appointment is embrocated on the surface of the blank to step 2 gained;
Step 4: the blank of step 3 gained is put into Drawing Die and carry out blanking and drawing, start to form the shape of required drawing part;
Step 5: the blank of step 4 gained is carried out to drawing again, further increase the drawing part degree of depth, make the shape of blank more close to drawing part;
Step 6: the drawing part of step 5 gained is carried out to drawing again, increase again the drawing part degree of depth, make the shape of blank basic identical with drawing part;
Step 7: the drawing part of step 6 gained is carried out to drawing again, increase again the drawing part degree of depth, make the shape of blank be equal to drawing part;
Step 8: the semi-finished product of step 7 gained are carried out to deburring processing;
Step 9: the semi-finished product of step 8 gained are carried out to Shape correction, obtain finished product.
Described step 4 and five, step 5 and six, is accompanied by the thermoplastic processing to blank between step 6 and seven, embrocate if desired the lubricating oil of appointment after softening processing.Described step 4, five, six and seven need be embrocated the lubricating oil of appointment before drawing in Drawing Die with blank contact position.Thereby being the sizes of dwindling mao accessory bottom surface, described step 4, five, six and seven drawing increase the degree of depth of blank.By adopting four drawing to become final finished product, and before drawing, have process a series of early stages: softening, cleaning and lubricated, number of drawing is reduced, efficiency improves, and the softening and lubricated to material of also following in drawing process, further can make efficiency of drawing improve, whole invention is simple to operation, in being applicable to produce.
