Abstract
The utility model discloses a throat mould, including a taper sleeve, the taper hole diameter in this taper sleeve is crescent from taper sleeve one end to the other end, the one end that the taper sleeve has less diameter taper hole outwards is equipped with a base and leader in proper order, pass the taper hole and be equipped with a plug, this plug one end with base fixed connection, the base encircles and is equipped with the interior claw of eight lamellas to an in -connection annular seating, this annular seating surface equidistance, interior claw can draw in in or open on the annular seating, interior claw passes expose its tip behind the taper hole. The utility model provides a throat mould can better mouth of pipe circularity at the in -process of throat, does benefit to the welding.
Description
Technical field
The utility model relates to a kind of reducing die.
Background technology
In the manufacturing process of stainless steel tube, in order to meet welding requirements, need the stainless steel tube mouth of pipe to reduce, existing reducing die, when reducing, can cause reducing unstable, lose circularity larger, make pipe dock insertion, or there will be excesssive gap after pipe docking insertion, gapless situation on one side, impact welding, pipe fitting burn-through when causing welding.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of reducing die, can better mouth of pipe circularity in the process of reducing, is beneficial to welding.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of reducing die, comprise a tapered sleeve, the taper hole diameter in this tapered sleeve increases to the other end gradually from tapered sleeve one end; One end that described tapered sleeve has small diameter taper hole is outwards provided with a base and leader successively; Be provided with a plug through taper hole, this plug one end is fixedly connected with described base; Described base inwardly connects an annular seating, and this annular seating surface is equidistantly equipped with pawl in eight lobes, and described interior pawl can draw in or open on annular seating; Described interior pawl exposes its end through after described taper hole.
The utility model provides a kind of reducing die, can better mouth of pipe circularity in the process of reducing, is beneficial to welding.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.
The sectional view of the reducing die that Fig. 1 proposes for the utility model embodiment.
The stereogram of the reducing die that Fig. 2 proposes for the utility model embodiment.
1, tapered sleeve 2, base 3, handle 4, annular seating 5, interior pawl 6, plug.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As illustrated in fig. 1 and 2, a kind of reducing die, comprises a tapered sleeve 1, and the taper hole diameter in this tapered sleeve 1 increases to the other end gradually from tapered sleeve 1 one end; One end that described tapered sleeve 1 has small diameter taper hole is outwards provided with a base 2 and leader 3 successively; Be provided with a plug 6 through taper hole, this plug 6 one end is fixedly connected with described base 2; Described base 2 inwardly connects an annular seating 4, and this annular seating 4 surface is equidistantly equipped with pawl 5 in eight lobes, and described interior pawl 5 can draw in or open on annular seating 4; Described interior pawl 5 exposes its end through after described taper hole.
During use, plug 6 stretches out and pawl 5 in 8 half is opened in the larger-diameter side of taper hole, is placed on by pipe inside plug 6, drive plug 6 and interior pawl 5 entirety to an end motion of taper hole small diameter manually or automatically, along with taper hole diameter is gradually little, interior pawl 5 draws in, realizes the reducing of pipe.
Above-described is only the preferred embodiment of a kind of reducing die provided by the utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
