As shown in connection with fig. 1, according to an embodiment of the invention, providing a kind of pipe fitting processing unit (plant).
Specifically, pipe fitting processing unit (plant) includes installation pedestal, reducing device and expanding device.Reducing device and installation pedestal It is connected, reducing device is used to carry out necking processing to pipe fitting to be processed.Expanding device is connected with installation pedestal, reducing device Flaring processing is carried out to pipe fitting to be processed, reducing device is disposed adjacently with expanding device.
Preferably, expanding device is located at the lower section of reducing device.Setting in this week can reduce pipe fitting processing unit (plant) in level The occupied space in direction improves the practicability of the pipe fitting processing unit (plant).
Wherein, expanding device and reducing device can be movably disposed in the horizontal direction.Setting can facilitate to pipe in this way Part carries out flaring or necking operation.Certainly, in the present embodiment, expanding device and reducing device can be arranged to synchronizing moving Or the mode of different moved furthers.
According to another aspect of the present invention, a kind of method for processing pipe fitting is provided, method is using in above-described embodiment Pipe fitting processing unit (plant) processes pipe fitting to be processed, method includes the following steps: using reducing device to pipe fitting to be processed 10 linkage section 11 carries out necking processing, so that the internal diameter of linkage section 11 is less than the outer diameter of pipe fitting to be cooperated.Using expanding device Flaring processing is carried out to pipe fitting 10 to be processed, so as to be greater than pipe fitting to be cooperated through the internal diameter at flaring processing on linkage section 11 Outer diameter, to form circular orientation portion 12 on the outer surface of linkage section 11.Using the matter for the fitting structure that this method processes Amount effectively improves, and is effectively shortened the process duration of pipe fitting processing positioning region.
Wherein, expanding device is less than the length of linkage section to the length of linkage section flaring processing.It can be protected using which Card forms circular orientation portion in connecting tube.Further, the length of linkage section be L1, linkage section through expanding device flaring Length is L2, wherein L1-L2=2mm.
Specifically, it is 12mm that this method, which includes the outer diameter of pipe fitting to be processed, in mating connection wait match with pipe fitting to be processed The outer diameter for closing pipe fitting is 9.52mm, carries out necking processing to linkage section using reducing device, the outer diameter of treated linkage section is 11.4mm, the internal diameter of treated linkage section are 9.4mm, and the length of treated linkage section is 12mm.Using expanding device pair Through reducing device, treated that linkage section carries out flaring processing, and the internal diameter through expanding device treated linkage section is 9.7mm.Through The length of expanding device treated linkage section is 10mm.
According to another aspect of the present invention, a kind of fitting structure is provided, fitting structure is added by pipe fitting in above-described embodiment The method of work processes to be formed.
Specifically, using the processing unit (plant) of the application and processing method, after the pipe end shrink mouth for solving processing fitting structure It is got ready again, needs process progress in two steps, a material transfer is needed to cause pipe fitting manufacturing procedure multiple between different processes Miscellaneous problem.Solve and get depth ready in the prior art and be easy there are error, get position wall thickness reduction ready, abnormal conditions get ready compared with The problem of leading to rear process welding quality deeply.It solves pipe fitting to produce the pipe end molding that needs to come into operation, get two kinds of equipment ready Problem.
The case where needing necking and inscribed pipeline for the pipe end of fitting structure, first carries out a necking, necking for pipe end Its internal diameter is less than cooperation pipeline outer diameter afterwards, then is once flared, and flaring length is 2mm smaller than first time necking length, in flaring Diameter is greater than cooperation pipeline outer diameter, in this way, being formed the circular orientation portion of a circle ∮ 2 outside second of flared section, it is fixed to realize Position.
By taking Φ 12 × 1 and Φ 9.52X0.71 pipe are welded to connect as an example, first by 12 × 1 pipe necking of Φ to outer diameter OD Φ 11.4, Internal diameter is 9.4mm at this time, matches pipe outside diameter, length 12mm less than interior, then be flared to internal diameter ID Φ 9.7 × 10, length is than for the first time Necking short 2mm, length 10mm, material is thus formed the circular orientation portions of a circle ∮ 2, realize positioning.
Using the processing method, it is only necessary to carry out necking, flaring operation, cancellation is got ready, transports, and process, positioning ring are simplified It is more preferable to locate wall thickness relative positioning point consistency, improves reliability more preferably.It is i.e. processable using a pipe end forming equipment, it takes The investment for the dotting equipment that disappears, significantly reduces production cost.The production method is easy to operate, no longer needs to beat using dotting equipment Point, simplifies production process, and to compare anchor point processing dimension consistency preferable for positioning ring, improves product quality.
It needs to carry out machine-shaping to pipe end when being welded to connect using the copper pipe of different tube diameters, welds cooperation insertion to meet The requirement of depth and welding procedure to fit clearance.The case where necking and inscribed pipeline are needed for pipe end, it is necessary to play positioning Concave point, to control two pipe lengths of fit and fit clearance.Using the fitting structure processing unit (plant) determining to the pipe end of fitting structure Bit architecture processing forms circular orientation portion using the processing method that a contracting one is expanded, effectively improves the processing matter of fitting structure Amount.
In the prior art, the tube end maching specification for beating positioning pit has following seven kinds:
1,9.52 × 0.71 necking ID Φ 7.2 × 8 of Φ;
2,12 × 0.8 necking ID Φ 9.7 × 10 of Φ;
