Abstract
The invention discloses a machining technique of a copper bush. The machining technique comprises steps as follows: a, the use amount of a copper substrate material is calculated according to the copper bush part; b, the copper substrate material is rolled into a tubular structure, the distribution direction of fibers coating the surface of the copper substrate material is consistent with the circumferential direction of the pipe diameter of the copper bush during rolling; c, one port of the copper bush is molded once by a mold, so that the port is molded once; then a second port is machined and molded once, and the form and geometric tolerance requirement of the cooper bush part is met; d, finally, two openings of the copper bush part are machined through a CNC machining center, and a finished product is obtained. With the adoption of the method, a mold extrusion molding process has the characteristics of high efficiency, rapidness, stability and reliability, the requirement of the part fiber direction is met, the shape and size of the two ports of the copper bush are guaranteed, the surface quality requirement is met, and the size consistency is good. The method is applicable to mass production, and the machining quality is stable and reliable.
Description
Technical field
The present invention relates to lining processing technique field, in particular to the technological method for processing of a kind of copper bush.
Background technology
Along with the development of science, lining part can be widely applied to the various aspects of aerospace field, such as aviation
Aerospace craft parts, missile parts and components and boats and ships parts etc., in actual life, it is used for machining factory's inspection and sets
Standby, precision instrument etc..Although such part utilizes extensively, but its processing is a great problem.
The processing method of existing copper lining is, by using forming cutter extruding to expand the mechanical processing technique of port on lathe
Method, the percent defective using this process to process is the highest, also add manufacturing cost.And the most easily there is crackle in its port
Phenomenon, and due to the opening-like structure of tubulose, use extruded purpose to be unable to reach its purpose.Processing for copper bush
In process, tubing is utilized to form through turning cutting tool turnery processing, because its material is copper material tubing, and the material used
Being T2 material, machine direction is along tubing axial direction.And its machine direction of this part requirements is along copper bush caliber circumference
Direction, so using existing tubular object extruding obviously can not meet requirement.Meanwhile, during sheet fabrication, after molding tubulose
There is a breach seam, then when processing two ends port on lathe, difficulty is bigger, it is impossible to ensure its two-port size and shape requirement.By
This is visible, uses existing technological method for processing can not meet copper bush part product and produces the requirement of processing in enormous quantities.
Summary of the invention
The technical problem to be solved in the present invention is for problem present in background technology, proposes the processing of a kind of copper bush
Process, changes the mechanical process technique using molding cutter extruding to expand port on lathe into extrusion process,
To solve traditional method is difficult to the problem of processing for lining two-port size and shape, there is good manufacturability and economy
Property.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is: the technological method for processing of a kind of copper bush,
It comprises the following steps:
The contour structures of a, as required shaping copper bush part, calculate required cuprio plate uses doses；
B, take the cuprio plate materials amount calculated and be rolled into tubular structure, in coiling process so that it is cuprio plate surface-coated
Direction of fibre distribution is consistent with copper bush caliber circumferencial direction；
C, one port by the most once-forming copper bush of mould so that it is one-shot forming；Reverse end for end processing the most again
Two-port netwerk so that it is one-shot forming, meets the Geometrical Tolerance Principle of copper bush part；
D, two openings of last copper bush part use numerical control machining center to machine, and obtain finished product.
Further, the technological method for processing of described a kind of copper bush, wherein said cuprio plate uses thickness to be 1mm
T2 sheet material.
Further, the technological method for processing of described a kind of copper bush, wherein said cuprio plate is rolled into the work of tubulose
Sequence is to use on traditional manual machining production line, or uses on semi-automatic and automatic production line.
Using the technological method for processing of a kind of copper bush of the present invention, compared with prior art, its beneficial effect exists
In: material has obtained effective utilization, is greatly saved cuprio plate, the extruded technological method for processing of mould has efficiently,
Quickly, reliable and stable feature, both met the requirement of part machine direction, it is ensured that the shape of copper bush two-port and size,
Also reaching surface quality requirements, dimensional uniformity is good.It is greatly saved production cost and the cost of charp tool simultaneously.Meanwhile, the method
Be applicable to produce in enormous quantities, crudy stable, reliable, it is possible to be popularized and applied to the part of the good metal material of all kinds plasticity
Processing industry.
