S6：Fine cut, further accurate trimming is carried out according to pre-set dimension by stepped tube body bottom outer rim；
S7：Chamfering, fastens stepped tube body, chamfering at punching press using the mould with chamfering；
S8：Close up, the bottom of stepped tube body is inwardly gradually bent, finally closing is closed up；
S9：Sizing, finished product is carried out last Shape correction by shaping mould.
In the S2 steps, first segment drawing uses mould, and for columned first mould, second segment drawing uses mould
For the second mould of stepped cylindrical, the second mould bottom interior diameter is identical with the first mould interior diameter, its top layer interior diameter
Less than the first mould interior diameter.
First mould is combined with the first punch, and second mould is combined with the second punch, and first punch is
Cylindric, its diameter and the first mould interior diameter coordinate, and second punch is cylindric, its diameter and the second mould interior diameter
Coordinate.
In the S5 steps, using the continuous punching of multistation, punching needle is arranged at stepped tube body side, by telescopic device
Drive its flexible tube wall that pierces through to be punched out, then transplant to next station, by index disc spins predetermined angle again into
Row punching.
In the S8 steps, continuously closed up using multistation, each station is provided with closing in cavity, by gradually by ladder
The bottom press-in closing in cavity of shape tube body gathers its deformation, is finally completed closing in.
The present invention operation principle be：Solve the problems, such as that background technology proposes by the way of highly integrated every process,
Unified allocation of resources control is carried out by control system by integrated technique and carries out work preface moderate.It is preset with program controling module each
The processing program of mechanism, via central processing module and each mechanism be electrically connected control the operating status of its each several part circuit into
Row machining posture controls so that each mechanism is able to that Each performs its own functions, and processing technology is completed in the division of labor.Information storage module is used to store journey
Sequence control module needs the data stored.In each mechanism, the station of each mechanism of transport mechanism series connection, by stock metal plate successively
By sawing sheet, drawing, pre-shaped, punching, fine cut and closing in, processing is completed.Wherein sawing sheet is that raw material is cut into suitable processing
The metal derby of size；Drawing is to use stamping forming principle, two sections of continuous punching drawing, and first segment drawing forms metal tube
Body, second segment reduce punch diameter punching press again on the basis of first segment, the tube body that first segment is formed is formed with second segment
Tube body into a ladder；Washing pipe wall side opening；Precision trimming clout, after its bottom excess waste is cut off, passes through closing mechanism
Its bottom is closed up.
Beneficial effects of the present invention are：Highly integrated automatic machining device is formed by whole processing technology, is reduced
Floor space, add processing efficiency, shortens process time, improves production success rate.
