Abstract
The invention provides a machining technology for a Y-shaped three-way pipe, relating to a machining technology for the Y-shaped three-way pipe that is frequently used for refrigeration machines and air-conditioning pipelines. The machining technology comprises the following machining steps of 1) clamping: positioning one end of the pipeline to be machined and tightly clamping the pipeline on a machine tool die; 2) die clamping and installing: clamping and installing dies 1, 2 and 3 on a machine tool according to designated stations; 3) primary machining: leading the die 1 to correspond to the pipeline to be machined coaxially; carrying out primary punching expanding to one end of the pipeline to be machined, thus enlarging the machining end to comply with the specified shape of round tube; 4) second time of machining: leading the die 2 to correspond to the pipeline to be machined coaxially; carrying out secondary punching to one end of the pipeline to be machined, thus forming the machining end to comply with the specified shape of elliptic tube; and 5) third time of machining: leading the die 3 to correspond to the pipeline to be machined coaxially; carrying out third rolling to one end of the pipeline to be machined, thus forming the machining end to comply with the specified shape of two tubes. The machining technology has simple procedure and the three-way pipe has good precision and consistency.
Description
Technical field
The present invention relates to the processing technology of a kind of Y-type three way type pipe commonly used in a kind of refrigeration machine and the air-conditioning duct.
Background technology
Y type mini three links are a kind of shunt accessories commonly used in refrigeration machine and the air-conditioning duct, just a pipeline are divided into two-way or are merged into one tunnel conversion accessory by two pipelines, and its shape is just as the Y in the English capitalization, so be called Y-type three way type.(to call mini three links in the following text)
Mini three links generally adopt red copper or brass tube to carry out enlarging, flattening, moulding, finish towards multiple working procedures such as buds at punch press through multiple (paying) particular manufacturing craft.Its mould investment is big, and the manufacturing cycle is long, complex procedures (loading and unloading of multiple tracks mould and workpiece, clamping and debugging etc.), and precision is difficult to guarantee defectives such as uniformity.
Summary of the invention
Technical problem to be solved by this invention provides the brand-new processing technology of a kind of Y-type three way type pipe, and this technique process is simple, the formed precision high conformity.
Technical scheme of the present invention is: procedure of processing is:
1) material folding: with the end location of pipeline to be processed, and be clamped on the machine tool mould;
2) clamping mould: mould one, two, three is pressed appointment station clamping to lathe;
3) time processing: mould one is coaxial corresponding with pipeline to be processed, treat process pipeline one end and do once to expand to dash, make the processing end increase pipe shape up to specification;
4) secondary operations: mould two is coaxial corresponding with pipeline to be processed, treat process pipeline one end and make the secondary stamp, make processing end moulding oval tubulose up to specification;
5) three processing: mould three is coaxial corresponding with pipeline to be processed, treat process pipeline one end and do three roll extrusion, make processing end moulding two pipe shapes up to specification.
Described mould one comprises circular enlarging drift.
Described mould two comprises oval shaping drift.
Described mould three comprises two round mandrels that axis is parallel, and left and right sides correspondence position is established one group and the vertically disposed roll extrusion wheels of two plugs at least between the plug, two plugs and rolling wheel fabric across shape.
Advantage of the present invention is:
1) the present invention adopt rammer, dash, the roll extrusion assembling process, working (machining) efficiency is very high, and Y-type three way type pipe of the present invention is as long as a clamping, adopt different moulds to press the station permutation and combination then, disposable continuously to its workpiece implement to upset, dash, rolling and processing, realizes disposable enlarging, shaping, moulding, the whole operations of pressure bud finished.Change in the past repeatedly the manufacturing defect that operations such as die change, clamping, debugging produce fully, improved machining accuracy and operating efficiency;
2) the selected mould structure of the present invention is simple, conceives exquisitely, and die manufacturing cycle is short, and long service life the more important thing is that die manufacturing cost is low, for the common die cost 1/10th less than.

The specific embodiment
As a kind of specific embodiment of the present invention, the present invention is placed on three moulds and pipeline to be processed on the three station rammer riveters, and it carries out according to the following steps:
1) the circular enlarging drift of mould one is aligned to the processing end of pipeline to be processed, treats process pipeline and implement punching press, make the processing end be shaped to pipe shape up to specification;
2) with the dislocation of mould one and pipeline to be processed, mould two is aligned to the processing end of pipeline to be processed, treat process pipeline and carry out secondary reshaping, be oval tubulose up to specification with original pipe shape integer;
3) at last mould three is aligned to the processing end of pipeline to be processed, two plugs 1 of mould three are inserted the location of carrying out in the elliptical tube elliptical tube, two roll extrusion wheels 2 of left and right sides carry out roll forming from the centre to elliptical tube between two plugs 1 by being arranged on simultaneously, the end that compresses of two little pipes and pipeline to be processed forms the Y-type three way type pipe to make elliptical tube become independently.
The present invention is further, as expand and make one minute three, one minutes four pipes ... Deng, the present invention also can arrange many core assemblies rod and rolling wheel, same disposable continuously to its workpiece implement to upset, dash, rolling and processing, realizes disposable enlarging, shaping, moulding, the whole operations of pressure bud finished.
