Abstract
The utility model discloses a pipe necking die assembly comprising a pipe necking die group, a die sleeve for clamping and fixing the pipe necking die group, and a positioning rod for penetrating through a pipe fitting, wherein the positioning rod is positioned in a central hole of the pipe necking die group and one end of the positioning rod is fixed in the die sleeve; the pipe necking die group comprises a pipe necking die for necking the middle of the pipe fitting and an opening necking die for necking the opening of the pipe fitting; the pipe necking die and the opening necking die are shaped independently; and the pipe necking die group also comprises a plurality of gaskets which can be placed between the pipe necking die and the opening necking die, or between the opening necking die and the die sleeve. The pipe necking die can be adjusted automatically according to pipe necking requirements; and the requirements on different lengths of pipe opening necking and middle necking can be met.
Description
Technical field
The utility model relates to the pipe fitting process equipment, particularly a kind ofly can tighten up the pipe-reduction mold assembly of pipe fitting bore according to draw length demands of different.
Background technology
In the prior art, need carry out draw processing, exactly pipe fitting one end mouth of pipe bore tightened up pipe fitting; And the pipe fitting middle part also need be tightened up; So that satisfy the needs of equipment, usual method is: as shown in Figure 1, and integrated pipe-reduction mold assembly of Design and Machining; It comprises pipe-reduction mold group 62, the die sleeve 61 of fixing this pipe-reduction mold group and the backstay (not shown) that is positioned at the centre bore of this pipe-reduction mold group; This backstay one end is fixed in this die sleeve 61, and this pipe-reduction mold group is integrally formed, and has the draw mould 621 that tightens up pipe fitting mouth bore, the Closing in die 622 that tightens up pipe fitting central tube footpath.Because this pipe-reduction mold group is integrally formed, thus for the different bores of pipe fitting, need to change different pipe-reduction molds, and also different for the length between the draw in the middle part of the pipe fitting mouth of pipe draw and the pipe fitting, also need change pipe-reduction mold, increase cost like this.
Summary of the invention
In order to remedy above deficiency, the utility model provides a kind of pipe-reduction mold assembly, can regulate pipe-reduction mold automatically according to draw requirement.Satisfy the different length between the mouth of pipe draw and the middle part draw.
The technical scheme of the utility model is achieved in that a kind of pipe-reduction mold assembly; Comprise the pipe-reduction mold group, the die sleeve of this pipe-reduction mold group that is fixedly clamped and the backstay that is used to wear pipe fitting; This backstay is positioned at the centre bore of this pipe-reduction mold group; And an end is fixed in this die sleeve, and this pipe-reduction mold group has draw mould that tightens up the pipe fitting mouth and the Closing in die that tightens up the pipe fitting middle part, and this draw mould and Closing in die are independent moulding.
As the further improvement of the utility model, this pipe-reduction mold group also has and can be positioned between this draw mould and the Closing in die, perhaps is positioned over a plurality of pads between this Closing in die and the die sleeve.
The useful technique effect of the utility model is: said pipe-reduction mold group has draw mould that tightens up the pipe fitting mouth and the Closing in die that tightens up the pipe fitting middle part; This draw mould and Closing in die are independent moulding; Pipe fitting to be processed wears the location through backstay; Because this draw mould and Closing in die are independent moulding, can this draw mould of free adjustment and Closing in die between spacing, thereby spacing between the draw in the middle part of the free adjustment pipe fitting mouth of pipe draw and the pipe fitting.
Further; This pipe-reduction mold group also has and can be positioned between this draw mould and the Closing in die; Perhaps be positioned over a plurality of pads between this Closing in die and the die sleeve; Length can be adjusted through a plurality of pads of placing between the draw of the pipe fitting mouth draw and pipe fitting middle part like this, realizes thus utilizing said pipe-reduction mold group to satisfy the requirement of different length between the mouth of pipe draw and the middle part draw, has practiced thrift die cost.

2---die sleeve L---draw spacing
The specific embodiment
In conjunction with Fig. 2 and Fig. 3, below describe in detail:
A kind of pipe-reduction mold assembly; Comprise pipe-reduction mold group 1, the die sleeve 2 of this pipe-reduction mold group 1 that is fixedly clamped and the backstay that is used to wear pipe fitting, this backstay is positioned at the centre bore of this pipe-reduction mold group 1, and an end is fixed in this die sleeve 2; This pipe-reduction mold group 1 has the draw mould 11 that tightens up the pipe fitting mouth; Also have the Closing in die 12 that tightens up the pipe fitting middle part, this draw mould 11 is independent moulding with Closing in die 12, because this draw mould and Closing in die 12 are independent moulding; Can this draw mould of free adjustment and Closing in die between draw spacing L, thereby spacing between the free adjustment pipe fitting mouth of pipe draw and the pipe fitting middle part draw.
In order to regulate the draw spacing L between this draw mould and the Closing in die better; This pipe-reduction mold group 1 also has and can be positioned between this draw mould 11 and the Closing in die 12; Perhaps be positioned over a plurality of pads 13 between this Closing in die 12 and the die sleeve 2; Pad 13 through between this draw mould 11 and Closing in die 12, placing some is as shown in Figure 3), thus spacing between the pipe fitting mouth of pipe draw and the pipe fitting middle part draw regulated; Through the pad 13 of placement some between this Closing in die 12 and die sleeve 2, thereby can regulate closing in rear end, pipe fitting middle part length.
Owing in the said pipe-reduction mold group, can only need to change the mould pad of different-thickness, just can satisfy different draw length according to different draw length; Different draw sizes also only needs to change different pipe-reduction molds and gets final product.
