Abstract
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 a fixture respectively, described fixture comprises the base and fastening hasp with semicircle low groove, it is characterized in that: described fastening hasp has semicircle upper groove, described base is fixedly connected with the conglobate clamping space of rear shape with described fastening hasp.Compared to prior art, when angle fitting chamfer angle mold of the present invention is used for carrying out chamfering to elbow, more firmly, closely can fix elbow, avoid, because tightness degree causes elbow processing defective not, improve the qualification rate of elbow chamfer machining.Further, the structure also by having the pin mould of arc groove also can guarantee that bend horizontal is placed, and can judge that whether elbow shaping is qualified fast.
Description
Technical field
The present invention relates to 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, retaining wall on slope, inspection.Retaining wall on slope operation wherein elbow is fixed on the groove by beveler car elbow two ends by drawing on chamfer mould.
But, the problem that the beveler ubiquity precision of prior art is not high, refer to 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 a fixture 20 respectively, and described fixture 20 comprises the base 21 and half polygonal fastening hasp 22 with semicircle low groove.Base 21 is fixedly connected with the clamping space 200 of rear formation one for fixing elbow 100 with fastening hasp 22.Due in prior art angle fitting chamfer angle mold, fixture adopts polygonal fastening hasp 22 to fix elbow 100, gap is there is between fixture 20 and elbow in chamfer process, tightness degree is inadequate, causing the elbow 100 produced not reach the requirement of national regulations 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 the technique of producing elbow control the both ends of the surface deflection of elbow, cause after chamfering, sometimes find that two end faces of elbow are not in same level, can only re-start shaping to elbow.In the process of shaping again, the chamfering of newly breaking out will be made again to be rubbed and the impact of the uncertainty such as collision, so need to polish to cut with abrasive machine, serious even needs chamfering again.And chamfering creates a new defective factor again, namely the height reduction of pipe fitting, finally causes product defective.So in bend forming technique, this procedure of retaining wall on slope is very important, because chamfering existing problems will directly have influence on the success rate that also connect of workman at the scene also in termination process and qualification rate.And there is structural defect in the angle fitting chamfer angle mold of prior art, gap is there is between fixture and elbow in chamfer process, tightness degree is inadequate, and cutter head and elbow edge produce huge frictional force makes elbow loosen in a mold, finally causes the product after chamfering defective.
Summary of the invention
In order to overcome the defect of prior art, the object of this invention is to provide a kind of angle fitting chamfer angle mold more closely can fixing 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 a fixture respectively, described fixture comprises the base and fastening hasp with semicircle low groove, it is characterized in that: described fastening hasp has semicircle upper groove, described base is fixedly connected with the conglobate clamping space of rear shape with described fastening hasp.
Preferably, on described base plate, be also provided with the pin mould of multiple support bend pipe.More preferably, described pin mould uniform intervals is distributed between the fixture of both sides.More preferably, described pin mould is distributed between the fixture of both sides along the center line uniform intervals of elbow back cambered surface.
Preferably, described pin mould has the arc groove matched with elbow outer circumference surface.
Further, the groove of described arc groove to be cross section be quarter circular arc.
Further, the top edge of described groove aligns with the center line of the convex surface of elbow.
Before placement elbow, first draw center line in the convex surface of elbow, then bend horizontal is placed on angle fitting chamfer angle mold of the present invention, by checking whether the center line of elbow back cambered surface aligns with the top edge of pin mould groove, can judge fast elbow shaping quality and whether will again through hydraulic press shaping.
Compared to prior art, adopt angle fitting chamfer angle mold fixed bend of the present invention to add stable first watch, improve the qualification rate of elbow chamfering.Further, by the structure with the pin mould of arc groove, the present invention also can guarantee that bend horizontal is placed, and can judge that whether elbow shaping is qualified fast.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Refer to 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 a fixture 40 respectively, described fixture 40 comprises the base 41 and fastening hasp 42 with semicircle low groove, described fastening hasp 42 has semicircle upper groove, and described base 41 is fixedly connected with rear formation for clamping the circular clamping space 400 of elbow 100 with described fastening hasp 42.On described base plate 30, be provided with the pin mould 50 of 3 support bend pipes.Described pin mould 50 is distributed between the fixture 40 of both sides along the center line uniform intervals of elbow 100 convex surface.
Refer to Fig. 3, described pin mould 50 has the arc groove 51 matched with elbow 100 outer circumference surface, and the groove of this arc groove 51 to be cross sections be quarter circular arc, 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 according to perfect condition elbow 100 whole very good of reforming process, after elbow 100 convex surface finishes center line, the position of center line overlaps with the height of three pin moulds 50 completely.As long as there is situation about not overlapping to occur, just show that two end faces of elbow 100 are not likely on same horizontal plane, directly check that the groove top edge gap of the center line of elbow 100 convex surface and three pin moulds 50 is how many, thus directly can judge that this elbow is the need of the shaping of again entering hydraulic press.
When angle fitting chamfer angle mold of the present invention is used for carrying out chamfering to elbow, more firmly, closely can fix elbow, avoid, because tightness degree causes elbow processing defective not, improve the qualification rate of elbow chamfer machining.Further, also can guarantee that bend horizontal is placed by the structure with the pin mould of arc groove, and can judge that whether elbow shaping is qualified fast.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
