Abstract
The invention provides an elbow chamfering mold which comprises a base plate. Clamps are respectively and fixedly installed at two sides of the base plate, and each clamp comprises a base and a fastening hasp, wherein the base is provided with a semicircular lower groove. The elbow chamfering mold is characterized in that the fastening hasp is provided with a semicircular upper groove, and a round clamping space is formed after the base and the fastening hasp are fixedly connected with each other. Compared with the prior art, the elbow chamfering mold has the advantages of being capable of more firmly and tightly fixing an elbow when the elbow is chamfered, avoiding disqualification of elbow machining due to insufficient tightness, and improving the pass rate of the elbow chamfering machining. Further, the elbow chamfering mold has the advantages of being capable of ensuring the horizontal placement of the elbow due to a structure of a feet mold which is provided with an arc groove, and rapidly judging whether bend shaping is qualified or not.
Description
Technical field
The present invention relates to the metal tube processing technique field, especially relate to a kind of angle fitting chamfer angle mold.
Background technology
At present, most bend forming technique all comprises the following steps: blanking, medium frequency pushing shaped, heat treatment, shaping, groove processing, check.Groove manufacturing procedure wherein is that elbow is fixed on chamfer mould by the beveler groove at car elbow processed two ends by drawing.
But, the not high problem of beveler ubiquity precision of prior art, see also Fig. 1 and Fig. 2, the angle fitting chamfer angle mold of prior art comprises: base plate 10, described base plate 10 both sides are installed with respectively a fixture 20, and described fixture 20 comprises base 21 and the half polygonal fastening hasp 22 with semicircle low groove.Base 21 is fixedly connected with one of rear formation and is used for the fixedly clamping space 200 of elbow 100 with fastening hasp 22.In the prior art angle fitting chamfer angle mold, fixture adopts polygonal fastening hasp 22 to fix elbow 100, there is the gap between fixture 20 and elbow in chamfer process, tightness degree is inadequate, the elbow 100 that causes producing does not reach the requirement of GB regulation when measuring end face deviation and both ends of the surface deflection, can only scrap.
And present stage the good detection means of neither one in producing the technique of elbow control the both ends of the surface deflection of elbow, two end faces that cause sometimes finding elbow after chamfering can only re-start shaping to elbow not on same level.The chamfering of newly breaking out is rubbed and the impact of the uncertainty such as collision, thus need to cut be polished with abrasive machine, the serious chamfering again that even needs.And chamfering has produced a new defective factor again, and namely the height of pipe fitting has reduced, and finally causes product defective.So in bend forming technique, it is very important that groove is processed this procedure, because the chamfering existing problems will directly have influence on the workman at the scene and the success rate that also connects and the qualification rate in termination process.And there is structural defective in the angle fitting chamfer angle mold of prior art, there is the gap between fixture and elbow in chamfer process, tightness degree is inadequate, and cutter head and elbow edge produce huge frictional force makes elbow loosening in mould, finally causes the product after chamfering defective.
Summary of the invention
In order to overcome the defective of prior art, the purpose of this invention is to provide a kind of can be the more fixing angle fitting chamfer angle mold of elbow, to improve the product percent of pass of elbow chamfering.
For achieving the above object, the invention provides a kind of angle fitting chamfer angle mold, it comprises base plate, the both sides of described base plate are installed with respectively a fixture, described fixture comprises base and the fastening hasp with semicircle low groove, it is characterized in that: described fastening hasp has semicircle upper groove, and described base is fixedly connected with the conglobate clamping space of rear shape with described fastening hasp.
Preferably, on described base plate, also be provided with the pin mould of a plurality of support bend pipes.More preferably, described pin mould is evenly spaced apart between the fixture of both sides.More preferably, described pin mould is evenly spaced apart between the fixture of both sides along the center line of elbow back cambered surface.
Preferably, described pin mould has the arc groove that matches with the elbow outer circumference surface.
Further, described arc groove is that cross section is the groove of quadrant arc.
Further, the top edge of described groove aligns with the center line of the convex surface of elbow.
Before placing elbow, first the convex surface at elbow draws center line, then bend horizontal is placed on angle fitting chamfer angle mold of the present invention, whether align with the top edge of pin mould groove by the center line of checking the elbow back cambered surface, can judge fast elbow shaping quality and whether will be again through the hydraulic press shaping.
Compared to prior art, adopt angle fitting chamfer angle mold fixed bend of the present invention to add first watch stable, improved the qualification rate of elbow chamfering.Further, the structure of the pin mould of the present invention by having arc groove can guarantee that also bend horizontal places, and can judge fast whether the elbow shaping is qualified.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
See also Fig. 2 (a) and Fig. 2 (b), the invention provides a kind of angle fitting chamfer angle mold, it comprises base plate 30, the both sides of described base plate 30 are installed with respectively a fixture 40, described fixture 40 comprises base 41 and the fastening hasp 42 with semicircle low groove, described fastening hasp 42 has semicircle upper groove, described base 41 and the circular clamping space 400 that is formed for clamping elbow 100 after described fastening hasp 42 is fixedly connected with.On described base plate 30, be provided with the pin mould 50 of 3 support bend pipes.Described pin mould 50 is evenly spaced apart between the fixture 40 of both sides along the center line of elbow 100 convex surfaces.
See also Fig. 3, described pin mould 50 has the arc groove 51 that matches with elbow 100 outer circumference surfaces, and this arc groove 51 is that cross section is the groove of quadrant arc, and the top edge of groove aligns with the center line of the convex surface of elbow 100.When measuring the both ends of the surface deflection numerical value of elbow 100, as long as elbow 100 is whole very good of shaping process, after elbow 100 convex surfaces were finished center line, the position of center line was to overlap with the height of three pin moulds 50 fully according to perfect condition.As long as there is situation about not overlapping to occur, two end faces that just show elbow 100 might be on same horizontal plane, directly check the center line of elbow 100 convex surfaces and three pin moulds 50 groove top edge gap what, thereby can judge directly whether this elbow needs again to advance the shaping of hydraulic press.
When angle fitting chamfer angle mold of the present invention is used for that elbow is carried out chamfering, can be more firmly, fixing elbow closely, avoid having improved the qualification rate of elbow chamfer machining because tightness degree causes elbow processing defective not.Further, the structure of the pin mould by having arc groove can guarantee that also bend horizontal places, and can judge fast whether the elbow shaping is qualified.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and implement according to this; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
