Abstract
A kind of pipe fitting expanding rounding machine, it is made up of arc support 1, mandrel 2, oil cylinder 3, case 4, spring 5, hand-operated direction valve 6,3 pull bar of oil cylinder shrinks band moving mandrel 2 and declines, 2 taper seat of mandrel compressing arc supports 1 internal conical surface, expand outwardly arc support 1, the pipe fitting internal wall of pipe orifice being enclosed within arc support 1 is gradually close to tube stay periphery, so as to realize mouth of pipe expansion and full circle.Re-compacted shaping after mouth of pipe expansion, greatly improves orifice configuration precision, and shaping quality is stable, simple to operate, shaping efficiency high, adapts to plurality of specifications pipe fitting shaping needs, solves the technical barrier of steel plate tubulation part bore depression shaping.
Description
Technical field
The invention belongs to metallic plate, pipe or substantially nothing cutting processing field in International Classification of Patents, are related specifically to pipe fitting
The expansion of the mouth of pipe and full circle.
Background technology
Often there is the difficult situation of mouth of pipe shaping out-of-round because of shaping or stitching error in steel plate tubulation part, usual shaping methods are
Pipe fitting is pressurizeed in shaping dies again full circle bore, and the method can not be by pipe fitting bore depressed area full circle.
Content of the invention
The present invention solve steel plate tubulation part bore be recessed shaping technical barrier, by bore is expanded after re-compacted become
Shape, greatly improves orifice configuration precision, and shaping quality is stable, simple to operate, shaping efficiency high, adapts to plurality of specifications pipe fitting whole
Shape needs.
Particular content：
A kind of pipe fitting expanding rounding machine, is characterized in that top for multistage round table-like tube stay, a kind of caliber bore specification of per grade of correspondence,
Every grade of tube stay by four to two ten circumferentially decile equally distributed arc support 1 be spliced, arc support 1 can radially and meanwhile expansion and
Shrink.
Described pipe fitting expanding rounding machine, is characterized in that circular cone mandrel 2,2 taper seat major part court of mandrel are installed in tube stay center
Upper, little support 1 internal conical surface with arc and coordinate upside down, 2 bottom of mandrel connects the pull bar of hydraulic jack 3, manually reversal valve 6
3 pull bar retracted downward of control cylinder declines mandrel 2, drives arc support 1 to expand outwardly, and tube stay diameter increases.
Described pipe fitting expanding rounding machine, is characterized in that tube stay periphery is case 4, install spring 5, bullet along 4 inwall of case
Spring 5 is corresponded with arc support 1, and manually 6 control cylinder of reversal valve, 3 pull bar rises, and promotes mandrel 2 up, and arc support 1 is in spring
The effect of 5 elastic force is lower inwardly to be resetted, and tube stay shrinks, and diameter reduces.
Description of the drawings
Fig. 1 is pipe fitting expanding rounding machine structural representation.
In figure：1 supports for arc, and 2 is mandrel, and 3 is oil cylinder, and 4 is case, and 5 is spring, and 6 is hand-operated direction valve.
Specific embodiment
Start hydraulic system, by 6 control cylinder of hand control valve, 3 pull bar up to top dead centre.Will be downward for the pipe fitting mouth of pipe
The tube stay of dimension is inserted in, is commutated by hand control valve 6,3 pull bar of control cylinder slowly shrinks downwards, band moving mandrel 2 is descending,
Its taper seat compressing arc supports 1 internal conical surface and expands outwardly, and makes tube stay enlarged diameter, is enclosed within pipe fitting internal wall of pipe orifice on tube stay gradually
It is close to tube stay periphery, so as to realize mouth of pipe expansion and full circle.
