Description
Technical field
The utility model relates to tool fixture, relates in particular to a kind of pipe fitting reducing processing mold.
Background technology
For pipe fitting used on air-conditioner, need to carry out reducing processing to the mouth of pipe place of pipe fitting, the size at pipe fitting mouth of pipe place is dwindled.
At present, be the method that uses mould cooperation rotary extrusion type for pipe fitting mouth of pipe place reducing processing, rotate and push the outer wall of processed pipe fitting by mold high speed, the diameter of the mouth of pipe is reduced to required size.
But, in process, mouth of pipe outer wall has a small amount of material by under the mill of mold work position, but because the working position of mould is mainly the working face that is located at reducing active section inside, this working face is complete circular configuration, together with what pipe fitting outer wall was tight with mold work position embrace, ground the material getting off and cannot be drained, but grinding repeatedly between pipe fitting outer wall and mold work position, constantly pile up and increase at mold work position, have so following impact:
1) make the size reduction of the working position of mould, the size decreases that causes processing pipe fitting is defective, makes cannot connect between pipe fitting.
2) form the not rough working surface of specification of one deck in the working position of mould, cause processed pipe fitting mouth of pipe outer wall rough, if pipe fitting is external other pipe fitting, when the rough meeting impact of outer wall is welded, scolder is mobile, has influence on the welding quality that the mouth of pipe connects.
3) the whole disc extruding of mold work position and pipe fitting outer wall high-speed friction, because contact-making surface is large, pipe fitting is to add man-hour caloric value large, cause the temperature at the processed mouth of pipe of pipe fitting place very high, thereby make pipe fitting mouth of pipe oxidation serious, surface produces more oxidation impurities, between pipe fitting when connecting welding, when oxidation impurities can affect welding, scolder is mobile, has influence on the welding quality that the mouth of pipe connects.
Utility model content
The utility model provides a kind of pipe fitting reducing processing mold, and object is to improve pipe fitting reducing crudy.
To achieve these goals, the technical scheme that the utility model is taked is:
A kind of pipe fitting reducing processing mold of the present utility model, comprises reducing active section, and reducing active section inside is provided with the working face for pushing pipe fitting, is provided with the chip area extending towards the outside wall surface of reducing active section from described working face in described reducing active section.

Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, object be help those skilled in the art to utility model of the present utility model conceive, technical scheme has more complete, accurate and deep understanding, and contributes to its enforcement.
In order to solve the problem of prior art existence and to overcome its defect, improve the reducing crudy of air-conditioner pipe fitting used, the technical scheme that the utility model is taked is:
As shown in Figures 1 to 4, a kind of pipe fitting reducing of the utility model processing mold, the reducing that is mainly used in air-conditioner pipe fitting used is processed.This mold integral is columniform cannula-like structure, and its cross section of crossing axis is convex shape.This mould comprises gripping section 1 and reducing active section 2, and gripping section 1 is for adding clamping die in man-hour, and gripping section 1 and reducing active section 2 lay respectively at the two ends of mould.Reducing active section 2 inside of this mould are provided with the working face for pushing pipe fitting, are also provided with the chip area 3 extending towards the outside wall surface of reducing active section 2 from working face in reducing active section 2.
Specifically, the working face in reducing active section 2 comprises the compressive plane axially setting gradually 21 and the undergauge face 22 along mould.Compressive plane 21 is taper seat, the bigger diameter end of this compressive plane 21 is to be positioned on the end face of reducing active section 2, on the end face of reducing active section 2, form the circular open that allows pipe fitting insert, the miner diameter end of compressive plane 21 is connected with undergauge face 22, and is arc transition between the two.Undergauge face 22 is the face of cylinder, with compressive plane 21 be coaxial, the hole internal diameter at undergauge face 22 places equates with the desired size of the processed pipe fitting mouth of pipe.Being carried out to reducing, pipe fitting adds man-hour, pipe fitting end face first contacts with compressive plane 21, along with the High Rotation Speed of mould, compressive plane 21 pushes pipe fitting outer wall, until the pipe fitting mouth of pipe inserts in the hole at undergauge face 22 places, pipe fitting outer wall and undergauge face 22 and compressive plane 21 are fitted, and as shown in Figure 5, the diameter of the processed pipe fitting mouth of pipe are reduced to reach the size needing.
Chip area 3 on reducing active section 2 is for radially running through the sidewall of reducing active section 2, and chip area 3 is also multiple along circumferentially arranging.Chip area 3 be shaped as rectangular channel, its length is parallel with the axis of mould, and is to extend to compressive plane 21 places from undergauge face 22.
As preferably, chip area 3 along circumferentially for being evenly arranged.
As preferably, as shown in Figure 2, chip area 3 arranges 4, and for being evenly arranged, the angle between adjacent two chip areas 3 is 90 degree.
As distortion embodiment, as shown in Figure 3, chip area 3 arranges 3, and for being evenly arranged, the angle between adjacent two chip areas 3 is 120 degree.
As another distortion embodiment, as shown in Figure 4, chip area 3 arranges 5, and for being evenly arranged, the angle between adjacent two chip areas 3 is 72 degree.
Below by reference to the accompanying drawings the utility model is exemplarily described.Obviously, the utility model specific implementation is not subject to the restrictions described above.As long as having adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; Or without improvement, above-mentioned design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
