Abstract
The invention provides to a spinning head capable of processing a slab to a bowl-and-dish-shaped sheet, relating to the improvement of a spinning head structure. The spinning head comprises a cake-shaped body, wherein the cake-shaped body is in an arc along two sides of a section of an axis; a circumference formed by most prominent points of the arc on the body and a curved surface which uses a section of arc line at the next section of the most prominent points as a bus forms a spinning feed working face; and the surface of the curved surface which uses a section of arc line at the previous section of the most prominent points is provided with a friction surface. The spinning head generates friction heat twice on a shaped workpiece, thereby achieving tempering temperature to improve the quality caused by internal stress of the workpiece. Furthermore, the friction surface of the invention also has the effect of improving the surface roughness of the workpiece.
Description
Technical field
The present invention relates to a kind ofly Sheet Metal Processing be become dish-shaped spinning head, relate in particular to improvement the spinning head structure by cold extrusion.
Background technology
Numerical control closed loop spoke spinning machine is mainly used in automobile spoke spinning, moulding.The spoke of mould pressing has not advantages such as uniform thickness, equal strength, good looking appearance; Can be applicable to the inner tube of a tyre and the different demands of tubeless wheel rim widely to spoke.Spoke spinning is a kind of composite spinning, and it has powerful extruding to revolve thin characteristics again to the characteristics of dull and stereotyped (automobile spoke steel plate special) existing conventional spinning.
It is cold extrusion shaped that rotary pressing processing belongs to, spinning head is applied with great extruding force to workpiece, make circular plate deformation be bowl dish, wheel hub shape, the position that deflection is bigger, the heat of the frictional heat that is produced, distortion heat is very big, even can make the plate part be kermesinus, and crush zone is not only accepted the conduction heat of high-temperature region.After the completion of processing, may cause the drip molding internal stress bigger, influence the quality of product.
Summary of the invention
The present invention is directed to above problem, after a kind of component shaping is provided, spinning head still keeps uniform CONTACT WITH FRICTION with workpiece, thereby secondary produces and can be used for improving the frictional heat of inner stress of work, and can improve workpiece surface roughness flat board is processed into dish-shaped spinning head.
Technical scheme of the present invention is: the body with round pie, described round pie body is curved along the both sides in the cross section in axle center, circumference that described arc most salient point constitutes on body and the curved surface that is bus with one section camber line of this hypomere are spinning feeding working face, and the described surface that is the curved surface of bus with one section camber line of most salient point epimere is provided with rubbing surface.
The radian of described rubbing surface is slightly larger than the radian of working face.
The present invention is provided with a circle rubbing surface above the spinning point of spinning head, changed the form of the whole surface smoothness unanimity of spinning head in the past.In the prior art, similar processing is disposable moulding feeding, reach the shaping terminal point after, break away from workpiece.Spinning head in primary feed, finish dull and stereotyped when dish-shaped distortion, big local in covert amount, can produce a large amount of heats, make the residual bigger internal stress of drip molding.And after the application invention, can when return, keep " knife back " and workpiece that uniform CONTACT WITH FRICTION is arranged, secondary produces frictional heat on the workpiece that has been shaped, reaches the temperature of " tempering ", to improve the quality problems that inner stress of work causes.In addition, rubbing surface of the present invention can also play the effect of improving workpiece surface roughness.

The specific embodiment
The present invention as Figure 1-3, body 1 with round pie, round pie body 1 is curved along the both sides in the cross section in axle center, circumference that arc most salient point 3 constitutes on body 1 and the curved surface that is bus with one section camber line of this hypomere are spinning feeding working face 4, and the described surface that is the curved surface of bus with most salient point one section camber line of 3 epimeres is provided with rubbing surface 2.
The radian of described rubbing surface 2 is slightly larger than the radian of working face 4.When body 1 is returned by the feeding path, have at least any can contact the outer surface of bowl and dish-shaped workpieces 5 in one section camber line of most salient point 3 epimeres.
Claims (2)
1. spinning head that flat board is processed into dish-shaped, body with round pie, described round pie body is curved along the both sides in the cross section in axle center, circumference that described arc most salient point constitutes on body and the curved surface that is bus with one section camber line of this hypomere are spinning feeding working face, it is characterized in that the described surface that is the curved surface of bus with one section camber line of most salient point epimere is provided with rubbing surface.
