Abstract
The utility model discloses a processing and forming mold of internal thread copper pipe which comprises an external mold and an internal mold. The external mold consists of a bearing connector, a steel ball, an end enclosure and a pair of spinning rings (4, 4 ditto) which are arranged in a bearing connector (1). The steel ball (5) is positioned in a pair of spinning rings (4, 4 ditto), an adjusting padding cushion (7) is provided between the bearing connector (1) and the end enclosure (6). The utility model has the advantages of simple structure, long life span and convenient adjustment and so on.
Description
Technical field
The utility model relates to the mould that a kind of tube forming is used, and belongs to a kind of inner thread copper tube forming mold.
Background technology
The mould of machining internal thread copper pipe generally is made up of outer mold, inner mold at present.As Fig. 5, outer mold shown in Figure 6 by shaft coupling 1 ', pair of bearings 4 ' (7203C), supporter 5 ', pad 6 ', steel ball 7 ', flat circle 8 ', lid 9 ', end cap 10 ' form.As shown in Figure 7 inner mold by screw thread core print 2 ', core bar 3 ', trip core 11, accessory combining 12, nut 13 form.Because the complex structure of this outer mold, cause that to join the mould difficulty big, operator's technical ability requires high, is unfavorable for the assurance of product quality.Because this outer mold is the some contact at inner screw thread copper pipe spinning process steel ball peace circle, the quick abrasion of mould, cause die life short, loss is big.Influenced by axial tensile force, one group of steel ball be cannot say for sure just at grade rotation at a high speed to misplace easily, influences crudy.Also because the adjustment inconvenience of the drafts of this outer mold, radial pressure in the time of can only adjusting machine-shaping by the steel ball of supporting plurality of specifications size realizes the generation of inner screw thread copper pipe profile of tooth, produces in batches to be difficult to guarantee crudy.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, long service life, inner thread copper tube forming mold easy to adjust are provided.
The purpose of this utility model is achieved in that it is made up of outer mold, inner mold; Outer mold comprises bearing joint, steel ball, end cap, also comprises a pair of spinning ring of dress in the bearing joint, and steel ball is arranged in a pair of spinning ring, and the adjusting pad is arranged between bearing joint and the end cap.
The utility model compared with the prior art because outer mold is simple in structure, institute is so that joining mould is easier to, operator's technical ability is less demanding, helps the assurance of product quality; Because a pair of spinning ring and the steel ball contact area of outer mold are big, the wearing and tearing that slow down mould increase the service life; Because radial pressure when the adjusting pad of outer mold is adjusted machine-shaping, not only can save the steel ball of supporting plurality of specifications size, and drafts is easy to adjust.

The specific embodiment
Present embodiment is made up of outer mold, inner mold.With reference to Fig. 1, Fig. 2, outer mold is by bearing joint 1, steel ball 5, end cap 6, a pair of spinning ring 4,4 ", regulate pad 7 and form." apposition position is concave arc ringwise, and steel ball 5 is arranged in the annular concave arc as shown in Figure 3 to adorn a pair of spinning ring 4,4 in the bearing joint 1 in ", steel ball 5 is arranged in a pair of spinning ring 4,4 ", a pair of spinning ring 4,4.Because a pair of spinning ring and steel ball contact area are big, the wearing and tearing that slow down mould increase the service life.End cap 6 lids are put on bearing joint 1, and end cap 6 lower ends withstand on spinning ring 4 " on, the pad 7 of adjusting is arranged between bearing joint 1 and the end cap 6.Regulate a pair of spinning ring 4,4 by the adjustment pad 7 that disposes different thickness " the gap, adjust the radial pressure of steel ball indirectly, reach the convenient purpose of adjusting to drafts.The adjustment of drafts can be undertaken by following formula:
Regulate the degree of depth of the thickness-end cap 6 of pad 7 thickness=bearing joint 1 fitting depth-2 times spinning ring 4
In the formula: no longer change after the degree of depth typing of the thickness of bearing joint 1 fitting depth, 2 times of spinning rings 4 (being meant single spinning ring thickness), end cap 6.
For in process of production, can in time the copper powder of spinning generation be discharged, at bearing joint spinning ring position place is installed, be laid with through hole 11.The centrifugal force that utilizes the bearing joint rotation to produce is discharged copper powder.With reference to Fig. 4, inner mold is made up of core bar 3, the screw thread core print 2 of core bar 3 one ends dress, trip core 8, annex 9, the nut 10 that core bar 3 other ends are adorned successively.Be equipped with the spinning ring 4,4 of different size ", steel ball 5, internal thread core 8 and corresponding positioning module, plug die just can process the internal thread of different size.Process every kind of specification internal thread and only use a kind of standard steel ball.The course of work of this Mould Machining inner screw thread copper pipe: shaft coupling 1 is connected to one by screw thread or bolt and high-speed electric expreess locomotive, the smooth copper pipe is to enter in the circle that steel ball 5 impales, the internal thread core 2 of inner mold is to place in the smooth copper pipe, the smooth copper pipe is subjected to the radial pressure of steel ball 5, the high speed rotation of steel ball makes smooth copper pipe compressive deformation, interact with the internal thread core 2 in the smooth copper pipe inwall, generate screw thread at smooth copper pipe inwall.If the thread tooth that generates is undesirable, carry out fine adjustment by changing the thickness of adjusting pad 7, thereby the gap of control spinning ring 4 reaches the radial pressure of adjusting steel ball 5, guarantees inner thread copper tube forming.
