Detailed description of the invention
In order to make the technical problem to be solved, technical scheme and beneficial effect clearer,
Below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that this place is retouched
The specific embodiment stated only in order to explain the present invention, is not intended to limit the present invention.
Present embodiments providing the numerical control cutting method of a kind of reducing Taper Pipe intersecting mouth, step is as follows:
S11, in three-dimensional software, lead wire finishing die, and utilize line mould to generate the stereomodel 100 of steel pipe truss.
S12, determine in stereomodel 100 need cutting a Taper Pipe be Pipe Cutting 1, with the end of Pipe Cutting 1
The steel pipe passed through mutually is that (Pipe Cutting 1 often holds traffic control 2 quantity passed through mutually to be at least one, it is also possible to be two in traffic control 2
More than root), and labelling reference point 10 between the two ends of Pipe Cutting 1, it is preferable that in order to avoid cutter
Collide with Pipe Cutting 1, reference point 10 be located proximate to the termination that Pipe Cutting 1 diameter is less.
S13, the position passed through with traffic control 2 phase respectively according to Pipe Cutting 1 two ends, obtain the first intersecting mouth 111
Profile and the profile of the second intersecting mouth 112.
S14, the target length according to after Pipe Cutting 1 cutting, reference point 10 space coordinates, Taper Pipe raw material 1 ＇
Diameter and length choose the first intersecting mouth fire location 11 and the fixing strong point 13 of Taper Pipe raw material 1 ＇.
And combine the first intersecting mouth fire location 11 to reference point 10 apart from the+the second intersecting mouth fire location 12 to ginseng
Examination point 10, apart from=Pipe Cutting 1 target length, calculates the second intersecting mouth fire location 12.
S15, below the fixing strong point 13 use bearing 14 support Taper Pipe raw material 1 ＇.
S16, according to the profile of first intersecting mouth fire location the 11, first intersecting mouth 111 and reference point 10

Make the first cutting process.Diameter, the profile of the second intersecting mouth 112 and slope according to another termination of Pipe Cutting 1
Bicker degree develops the second cutting process.Specifically, the first cutting process and the second cutting process all include
Intersecting mouth excision forming program.Further, the first intersecting mouth fire location 11 is by can manipulation circle of cutting equipment
Face is set or changes.
S17, by manual type, numerical control cutting equipment is moved to the first intersecting mouth fire location 11, open
First cutting process, the first intersecting mouth 111 of cutting Pipe Cutting 1, until the first intersecting mouth 111 cuts complete,
Then according to the numerical value of described displacement, numerical control cutting equipment sky runs to reference point 10, then automatically turns on
Second cutting process, until after the second cutting process terminates, the second intersecting mouth 112 cuts complete；I.e. complete
First intersecting mouth 111 and the cutting of the second intersecting mouth 112.
First phase is passed through by the reducing Taper Pipe intersecting mouth numerical control cutting method of the present embodiment by arranging reference point 10
The cutting process of mouth 111 and the second intersecting mouth 112 is together in series, thus cutting equipment can accurately arrive at
Second intersecting mouth fire location 12, it is achieved that the disposable Numerical control cutting of reducing Taper Pipe intersecting mouth；Ensure that and cut
Cut the Pipe Cutting 1 after the intersecting mouth of two ends consistent with the target length of anticipation.Meanwhile, whole cutting process is by cutting
The equipment of cutting completes, and therefore the molding effect of intersecting mouth and groove is stable and precision is high.
The reducing Taper Pipe intersecting mouth numerical control cutting method of the present embodiment improves the crudy that Taper Pipe passes through mutually, subtracts
Lack the manufacturing procedure of Taper Pipe intersecting mouth, compared to the mode of conventionally employed artificial cutting, it is not necessary to router,
The input of the workmans such as cutting work, polishing work, improves working (machining) efficiency, greatly reduces human cost.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Any amendment, equivalent and the improvement etc. made within bright spirit and principle, should be included in the present invention
Protection domain within.
