Abstract
The utility model discloses a spinning die on the spinning device of the metal tubular product. The utility model comprises a bottom seat and a spinning head arranged on the bottom seat, a die hole is arranged in the middle of the bottom seat, a dummy club is also arranged on the bottom seat, a steel ball is arranged on the dummy club, spanning flat rings are arranged at the outer sides of the steel ball and the dummy club, inclined cover plates are arranged between the spanning flat rings and the spanning head, and certain tapers are arranged at the contacting parts between the inclined cover plates and the steel ball. The utility model has the advantages that the spanning ring is changed into the spanning flat ring, to ensure that the contacting way between the steel ball and the metal tubular product is changed into point contact form cambered surface contact, the frictional force is reduced, the lubrication is convenient, therefore, the spanning dimension of the metal tubular product is more stable.
Description
Technical field
The utility model relates to the spinning mould on a kind of metal-pipe spinning apparatus.
Background technology
The spinning apparatus of metal pipe material mainly comprises: be arranged on the device front end the tube reducing mould, be arranged on the whole footpath mould of rear end and be arranged on spinning block in the middle of the device, existing spinning block is mainly ring, comprise: die sleeve, the centre of die sleeve offers nib, is provided with spinning in the die sleeve to ring, is provided with steel ball in the groove of spinning to ring, the number of steel ball is generally five, the upper end of steel ball is provided with cover plate, and the cover plate upper end is provided with spinning head, also is provided with pad between spinning head and die sleeve.But, this spinning block, when steel ball contacts with metal pipe material, be the cambered surface contact, frictional force is bigger, in when work, need regulate gap between steel ball by pad, because the production scene has a lot of metal fragments and lubricated remaining rubbish oil often to adhere on the pad, makes the spinning size instability of metal pipe material.
The utility model content
Technical problem to be solved in the utility model provides the spinning block on the metal-pipe spinning apparatus that a kind of frictional force is little, spinning is stable.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: the spinning block on a kind of metal-pipe spinning apparatus, comprise: base and the spinning head that is arranged on the base, the centre of base offers nib, also be provided with boss on the described base, boss is provided with as dried steel ball, in the arranged outside of steel ball and boss the flat ring of spinning is arranged, be provided with oblique cover plate between flat ring of spinning and the spinning head, tiltedly the contact portion of cover plate and steel ball is provided with certain tapering.
In order to make the utility model lubricated convenient, certain tapering is arranged in the end of described nib.
The utility model has the advantages that: ring is changed spinning into spinning flat ring, the steel ball and the way of contact between the metal pipe material contacts by cambered surface become a contact, reduce friction, the lubricated convenience makes the spinning size of metal pipe material more stable.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation that is provided with the metal pipe material device of spinning block described in the utility model.
Fig. 2 is the cutaway view Amplified image of the spinning block among Fig. 1.
Among the figure: 1, base, 2, spinning head, 3, nib, 4, projection, 5, steel ball, 6, the flat ring of spinning, 7, oblique cover plate, 8, metal pipe material, 9, the tube reducing mould, 10, nib, 11, the tube reducing core print, 12, connecting rod, 13, spinning block, 14, whole footpath mould, 15, nib, 16, the screw thread core print, 17, screw.
The specific embodiment
As shown in Figure 2: the spinning block on a kind of metal-pipe spinning apparatus, comprise: base 1 and the spinning head 2 that is arranged on the base 1, the centre of base 1 offers nib 3, be provided with certain tapering in the end of nib 3, also be provided with boss 4 on the described base 1, boss 4 is provided with as dried steel ball 5, in the arranged outside of steel ball 5 and boss 4 the flat ring 6 of spinning is arranged, be provided with oblique cover plate 7 between flat ring 6 of spinning and the spinning head 2, tiltedly cover plate 7 is provided with certain tapering with the contact portion of steel ball 5.
The course of work that is provided with the metal-pipe spinning apparatus of spinning block described in the utility model is: as shown in Figure 1, at first will need the metal pipe material 8 of spinning to import the tube reducing mould 9 of the front end that is arranged on spinning apparatus, be provided with tube reducing core print 11 in the nib 10 of tube reducing mould 9, the rear end of tube reducing core print 11 is connected with connecting rod 12, connecting rod 12 is located in spinning block 13 and is arranged on the nib (3 of whole footpath, device rear end mould 14,15) in, when metal pipe material 8 passes through, by tube reducing mould 9 it being carried out tube reducing handles, pass through spinning block 13 then, in the nib 3 of spinning block 13, be provided with screw thread core print 16, rotate by the steel ball 5 of the flat ring 6 of driven by motor spinning and the side that sets within it and oblique cover plate 7 (being arranged on the spinning head a 2) superhigh speed that is arranged on above the steel ball 5 by screw 17, realization is handled metal pipe material 8 spinning, steel ball 5 numbers of spinning block 13 are traditionally arranged to be five, certainly it is also passable to be set to four or six, the spinning amount that this can be according to actual needs and deciding.In the spinning process to metal pipe material 8, the flat ring 6 of spinning has certain wearing and tearing, and the two sides of the flat ring 6 of the spinning in the utility model can be used, and can prolong the service life of spinning block 13 by the face of changing the flat ring 6 of spinning.In the process of spinning, need be lubricated in addition, therefore, be provided with certain tapering, thereby increase the opening of nib 3, conveniently be lubricated operation in the end of nib 3 to steel ball 5.The metal pipe material 8 last whole footpath moulds 14 that pass through that were spun are put in order the footpath to it, finish the spinning task to metal pipe material 8.
