Abstract
The utility model discloses a copper pipe internal thread spinning device relates to metal material processing field, and existing copper pipe internal thread spinning device is four ball spinning devices, because the screw core head among the spinning device is very easily damaged to the effort that receives two relative steel balls simultaneously at the during operation, the screw thread, and device life is short, and the processingquality is poor, and the yield is low, the utility model designs a five ball spinning devices, makes the screw core head only receive the effort of a steel ball, has overcome the shortcoming of existing device, and it is not fragile to have the screw thread, and device long service life has improved processingquality, convenient operation's characteristics.
Description
Technical field
The utility model relates to metal material cold working field, the field that particularly makes internal thread.
Technical background
The moulding spinning process of metal current pipe fitting internal thread is generally all used the processing of four ball spinning apparatus, this spinning apparatus is by the screw thread core print that is positioned at the center, be with the spinning ring in screw thread core print outside, be evenly distributed with four steel balls in spinning ring inboard, four steel balls are to be contained in the retainer, with the relative position between the stationary balls.The processing copper pipe passes through between screw thread core print and steel ball when rolling, form internal thread at the copper pipe inwall, there is following problem in this spinning apparatus: because be the configuration of even number steel ball, the right opposite of every steel ball all has another steel ball corresponding, the screw thread core print is subjected to the active force of relative two steel balls simultaneously when high speed spinning, screw thread on the core print is subjected to very big power, very easily produce and collapse tooth, particularly screw thread that tooth depth is bigger and the more screw thread of bar number, especially true, the result has shortened the service life of spinning apparatus, and the thread root that comes out after damaging can scratch the processing tube inwall, and the remaining copper powder is exceeded standard, cleannes descend.Retainer is the special difficult apolegamy of making in addition, and when the specification of processing tubing changed, debugging was just very loaded down with trivial details, and steel ball relies on retainer to fix, and deflection is very little, and the size of internal thread guarantees that by the size of pipe centering capacity is poor basically; Behind the rotary press modelling, outer surface lines broad is prone to floral tube, and for light-wall pipe, outer surface causes scratch easily.In order to improve the crudy of tubing, improve yield rate, prolong the service life of spinning apparatus, must transform spinning apparatus.
Summary of the invention
The purpose of this utility model provides a kind of long service life, crudy height, copper pipe internal thread spinning apparatus easy to use.
The utlity model has a screw thread core print, be with the spinning ring, equally distributed five steel balls are housed in spinning ring inboard, only keep the lubrication gap between the steel ball in screw thread core print outside.
Five steel balls of the present utility model are fixed without retainer, closely be arranged in the spinning ring, the opposite of every steel ball is adjacent two spaces that steel ball causes, when rotary pressing processing, what the screw thread core print was subjected to a direction is the single face active force, and screw thread is not fragile, service life is longer, thereby reduced residual copper powder, improved cleannes, guaranteed inner surface quality; At the outer surface of tubing, because the steel ball solid matter, threading is even, has improved presentation quality; Also has convenience operation.

Fig. 2 is the utility model copper pipe internal thread spinning apparatus generalized section
The specific embodiment
Fig. 1 has shown the prior art of machining internal thread spinning apparatus, is screw thread core print 1 at the center of device, is with spinning ring 2 in screw thread core print outside, and equally distributed four steel balls 3 are housed in the inboard of spinning ring, and all steel balls all are contained in the retainer 4.Fig. 2 has shown the structure of the utility model copper pipe internal thread spinning apparatus, the center of device is a screw thread core print 5, be with spinning ring 6 in screw thread core print outside, equally distributed five steel balls 7 are housed in spinning ring inboard, steel ball is close to the spinning ring, only keep the lubrication gap between the steel ball, the copper pipe of machining internal thread passes through the space between screw thread core print and steel ball, is processed internal thread by the screw thread core print on the inwall of copper pipe.
Claims (1)
1. copper pipe internal thread spinning apparatus has the screw thread core print, is with the spinning ring in screw thread core print outside, it is characterized by in spinning ring inboard equally distributed five steel balls are housed, and only keeps the lubrication gap between the steel ball.
