Cutting mark；
Step 2: pressing the blanking of blanking figure, using pipeline section central diameter length of run as steel plate cutting width, each pipeline section, which irregularly passes through mouth, to be cut
Secant by subject to central diameter evolute, each pipeline section is corresponding pass through mouth to point of interface mark on steel plate, and steel plate be set play cutpoint and be
The interior curved point of bend pipe, blanking figure input Full-automatic numerical control cutting machine carry out steel plate Numerical control cutting, wherein irregularly pass through mouth line by
Dotted line is cut；
Step 3: the steel plate after cutting opens up groove by pressing direction, and mark is made in quadrangle, using press device by steel plate
It is pressed into semi-circular tube, two semi-circular tubes are welded into the circle processing of the school complete circle Guan Bingjing by groove；
Step 4: welding grasping straight section in complete circle pipe end, complete round tube hot bending shape is formed by single by grasping straight section
Rod piece, and cut off grasping straight section passes through mouth by irregularly pass through that mouth cutting dotted line is cut into complete round tube head end；
Step 5: will bend latter each section complete round tube is placed in moulding bed, by moulding bed control adjacent complete round tube pass through mouth line type and
The feature point of mouth is passed through in docking, and mouth is passed through in the docking for welding adjacent complete round tube, and single rod piece is spliced into hyperbolic rod piece, is completed big
Diameter hyperbolic irregularly passes through production of the mouth with bend pipe abnormity component.
Further, the pipeline section central diameter is that pipeline section diameter subtracts pipeline section wall thickness.
Further, the complete round tube hot bending shape carries out hot bending operation using heating in medium frequency.
Production method of the mouth with bend pipe abnormity component is irregularly passed through due to major diameter hyperbolic of the present invention and uses above-mentioned technical proposal,
That is any super-large diameter is irregularly passed through mouth expansion, passes through Full-automatic numerical control cutting machine blanking by this method by typesetting and blanking
Cutting, passes through mouth and is cut into interruption dotted line, is pressed into pipe, by welding grasping straight section hot bending shape, is cut into and irregularly passes through a mouthful end,
Mouth line type is passed through using moulding bed control and the feature point of mouth is passed through in docking, mouth is passed through in the docking for welding adjacent complete round tube, by single bar
Part is spliced into hyperbolic rod piece, completes major diameter hyperbolic and irregularly passes through production of the mouth with bend pipe abnormity component.Present method solves appoint
Meaning super-large diameter irregularly passes through the processing problems of mouthful bend pipe, overcomes the molding defect of conventionally employed casting steel casting, avoids nocuousness
Harm of the gas to human body and environment saves cost of manufacture, improves the application performance of abnormity component.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
Fig. 1 is that major diameter hyperbolic irregularly passes through mouth band bend pipe abnormity component schematic diagram.
Specific embodiment
Embodiment is as shown in Figure 1, major diameter hyperbolic of the present invention irregularly passes through production method packet of the mouth with bend pipe abnormity component
Include following steps:
Step 1: typesetting is carried out by the design drawing of abnormity component 1, by the multistage spline curve fitting of abnormity component 1 at multiple
Single line segment forms and facilitates the single rod piece of processing, marked in blanking figure each pipeline section 11 it is corresponding pass through mouth 12 to point of interface and
Interior curved point cutting mark；
Step 2: pressing the blanking of blanking figure, using 11 central diameter length of run of pipeline section as steel plate cutting width, each pipeline section 11 is irregularly passed through
Mouthful 12 cutting lines by subject to central diameter evolute, each pipeline section 11 is corresponding pass through mouth 12 to point of interface mark on steel plate, and steel is set
Plate plays the interior curved point that cutpoint is bend pipe, and blanking figure inputs the Numerical control cutting that Full-automatic numerical control cutting machine carries out steel plate, wherein does not advise
12 line of mouth is then passed through to be cut by dotted line；
Step 3: the steel plate after cutting opens up groove by pressing direction, and mark is made in quadrangle, using press device by steel plate
It is pressed into semi-circular tube, two semi-circular tubes are welded into the circle processing of the school complete circle Guan Bingjing by groove；
Step 4: welding grasping straight section in complete circle pipe end, complete round tube hot bending shape is formed by single by grasping straight section
Rod piece, and cut off grasping straight section passes through mouth by irregularly pass through that mouth 12 cuts that dotted line is cut into complete round tube head end；
Step 5: will bend latter each section complete round tube is placed in moulding bed 2,12 line of mouth is passed through by what moulding bed 2 controlled adjacent complete round tube
The feature point of mouth 12 is passed through in type and docking, and the docking for welding adjacent complete round tube passes through mouth 12, single rod piece is spliced into hyperbolic bar
Part completes major diameter hyperbolic and irregularly passes through production of the mouth with bend pipe abnormity component.
Preferably, the pipeline section central diameter is that pipeline section diameter subtracts pipeline section wall thickness.
Preferably, the complete round tube hot bending shape carries out hot bending operation using heating in medium frequency.
This method will irregularly pass through mouth expansion before passing through pipe crimping, and pass through with full-automatic numerical control blanking machine the interruption of mouth line
Property cutting then pipe crimping again, while using hot bending shape technology, complete the brake forming of single pipeline section；Edge is passed through when each pipeline section splices
The cutting dotted line of mouth line, which is cut into, passes through mouth, and position and the line style of mouth are passed through by moulding bed control, and two single rod piece splicings are in pairs
Curved bar part completes the processing that major diameter hyperbolic irregularly passes through abnormity component of the mouth with bend pipe.Hyperbolic is for adjacent in this method
For two rod pieces, since entire component is spliced by single rod piece, it is known as hyperbolic between rod piece two-by-two.
This method can solve the Bend of Pipes that any super-large diameter irregularly passes through mouth, and makes precision and can achieve design requirement, make
Make process without any pollution, avoid the influence to human body and environment, improve the material property of abnormity component, reduce material cost and
Processing cost, it is ensured that application of the abnormity component in engineering.
