Abstract
A kind of full-automatic machine for shrinking, including pipe-reduction mold group, the die sleeve for the pipe-reduction mold group that is fixedly clamped and the locating rod for wearing pipe fitting, the locating rod is located in the centre bore of the pipe-reduction mold group, and the die sleeve is fixed in one end, the pipe-reduction mold group has the draw mould for tightening up pipe fitting mouth and tightens up the Closing in die in the middle part of pipe fitting, the draw mould and Closing in die are molded to be independent, the pipe-reduction mold group also have can be positioned between the draw mould and Closing in die, or it is positioned over the multiple pads between the Closing in die and die sleeve, the present invention can require according to the draw, automatically adjust pipe-reduction mold.Meet the different length between the mouth of pipe draw and the middle part draw.
Description
Technical field
The present invention relates to pipe fitting process equipment, and more particularly to one kind can require according to draw length is different, tighten up pipe fitting mouth
A kind of full-automatic machine for shrinking in footpath.
Background technology
In the prior art, it is necessary to carry out draw processing to pipe fitting, exactly pipe fitting one end mouth of pipe bore is tightened up, and pipe fitting
Middle part is also required to tighten up, and to meet the needs of equipment, usual method is：As shown in figure 1, design processing one one into
A kind of full-automatic machine for shrinking of type, it includes pipe-reduction mold group 62, the die sleeve 61 for fixing the pipe-reduction mold group and positioned at the contracting
The die sleeve 61 is fixed in the locating rod (not shown) of the centre bore of pipe mold group, the locating rod one end, the pipe-reduction mold group
Integrally formed, and have and tighten up the draw mould 621 of pipe fitting mouth bore, tighten up the Closing in die 622 in pipe fitting central tube footpath.Due to
The pipe-reduction mold group is integrally formed, so the different bores for pipe fitting are, it is necessary to change different pipe-reduction molds, and for pipe
Length between the part mouth of pipe draw and the draw in the middle part of pipe fitting is different, it is also desirable to changes pipe-reduction mold, so increases cost.
The content of the invention
In order to make up above deficiency, the present invention provides a kind of full-automatic machine for shrinking, can be required according to the draw, automatically adjust contracting
Pipe mold.Meet the different length between the mouth of pipe draw and the middle part draw.
The technical proposal of the invention is realized in this way：A kind of full-automatic machine for shrinking, including pipe-reduction mold group, be fixedly clamped
The die sleeve of the pipe-reduction mold group and the locating rod for wearing pipe fitting, the locating rod are located at the centre bore of the pipe-reduction mold group
It is interior, and the die sleeve is fixed in one end, the pipe-reduction mold group has the draw mould for tightening up pipe fitting mouth and tightens up the closing in the middle part of pipe fitting
Mould, the draw mould and Closing in die are molded to be independent.
As a further improvement on the present invention, the pipe-reduction mold group also have can be positioned over the draw mould and Closing in die it
Between, or the multiple pads being positioned between the Closing in die and die sleeve.
The method have the benefit that：The pipe-reduction mold group has the draw mould for tightening up pipe fitting mouth and tightens up pipe fitting
The Closing in die at middle part, the draw mould and Closing in die are molded to be independent, and pipe fitting to be processed wears positioning by locating rod, due to this
Draw mould and Closing in die are molded to be independent, spacing between the draw mould and Closing in die can be freely adjusted, so as to free regulation pipe
Spacing between the draw in the middle part of the part mouth of pipe draw and pipe fitting.
Further, the pipe-reduction mold group also has and can be positioned between the draw mould and Closing in die, or is positioned over this
Multiple pads between Closing in die and die sleeve, length can pass through placement between the draw in the middle part of such the pipe fitting mouth draw and pipe fitting
Multiple pads adjust, and are achieved in meeting different length between the mouth of pipe draw and the middle part draw using the pipe-reduction mold group
It is required that die cost is saved.
Brief description of the drawings
Fig. 1 is a kind of sectional view of full-automatic machine for shrinking in the prior art；
Fig. 2 is the structural perspective of the present invention；
Fig. 3 is the structure sectional view of the present invention.
Control the figures above is supplemented as follows explanation：
1 --- pipe-reduction mold group 61 --- die sleeve
11 --- draw mould 62 --- pipe-reduction mold groups
12 --- Closing in die 621 --- draw moulds
13 --- pad 622 --- Closing in die
2 --- die sleeve L --- draw spacing
Embodiment
With reference to Fig. 2 and Fig. 3, it is described in detail below：
A kind of full-automatic machine for shrinking, including the die sleeve 2 of pipe-reduction mold group 1, the pipe-reduction mold group 1 that is fixedly clamped and be used for
The locating rod of pipe fitting is worn, the locating rod is located in the centre bore of the pipe-reduction mold group 1, and the die sleeve 2, the contracting are fixed in one end
Pipe mold group 1 has the draw mould 11 for tightening up pipe fitting mouth, also has the Closing in die 12 tightened up in the middle part of pipe fitting, the draw mould 11 and receipts
Mouth mold 12 is molded to be independent, because the draw mould and Closing in die 12 are molded to be independent, can freely adjust the draw mould and closing in
Draw spacing L between mould, so as to freely adjust spacing between the pipe fitting mouth of pipe draw and the pipe fitting middle part draw.
In order to preferably adjust the draw spacing L between the draw mould and Closing in die, the pipe-reduction mold group 1 also has and can put
It is placed between the draw mould 11 and Closing in die 12, or the multiple pads 13 being positioned between the Closing in die 12 and die sleeve 2, pass through
It is as shown in Figure 3 that a number of pad 13 is placed between the draw mould 11 and Closing in die 12), so as to adjust the pipe fitting mouth of pipe draw
The spacing between the draw in the middle part of pipe fitting；By placing a number of pad 13, Ke Yicong between the Closing in die 12 and die sleeve 2
And adjust closing in rear end length in the middle part of pipe fitting.
Due in the pipe-reduction mold group, according to different draw length, can need to only change the mold pad of different-thickness
Piece, so that it may meet different draw length；Different draw sizes, also need to only change different pipe-reduction molds.
