Specific embodiment
As shown in Fig. 1~2, the present invention includes the pre-molding module 1 being arranged between cope plate 18 and lower template 19, and
The final molding module 2 being arranged side by side with the pre-molding part；
The pre-molding module 1 includes the pre-molding chamber of precompressed upper impression 3 and the composition of precompressed lower impressions 4, is located at institute
The support U block 5 of pre-molding chamber side, the pipe end U block 6 ipsilateral and at the end socket of pipe fitting with the support U block 5 are stated,
And the unilateral U block 7 of support 5 opposite side of U block is set.
Support 5 top of U block is the recess for accommodating pipe fitting；The pipe end U block 6 is equipped with anti-string positioning plate 8 and positions
Plate.
As shown in figs. 34, the final molding module 2 includes final molding upper impression 9 and 10 groups of final molding lower impressions
At final molding chamber, the tube expansion hydraulic cylinder 11 of final molding chamber one end, and setting 11 phase of tube expansion hydraulic cylinder are set
The draw hydraulic cylinder 12 of opposite end.
The tube expansion hydraulic cylinder 11 is connected by swollen head positioning sleeve 14 with swollen head 15, the swollen head 15 protrude into it is described finally at
It is connect in type chamber with pipe fitting 13；
The draw hydraulic cylinder 12 is connected by drop-head positioning sleeve 16 with drop-head 17, the drop-head 17 protrude into it is described finally at
It is connected in type chamber with pipe fitting 13.
Application method of the invention is as follows:
Pre-molding
Pipe fitting 13 after completion bend pipe step is placed in the precompressed lower impressions 4 of pre-molding module 1, adjustment position enables pipe
The support U block 5 and unilateral U block 7 of 13 lower part of part play the role of support tubes 13, and the unilateral U block 7 is unilateral arc, for pipe
Part 13 is unfolded to curved outside in the preloading process and is designed, and the precompressed lower impressions 4 make a gap appropriate of keeping away also with full
Sufficient pipe fitting 13 is bent the requirement unfolded；Meanwhile the anti-string positioning plate 8 by one end of pipe fitting 13 on pipe end U block 6, it is described anti-
Positioning plate 8 of going here and there limits the radial displacement of pipe fitting 13.It is opened after being molded precompressed upper impression 3 and precompressed lower impressions 4 by hydraulic press,
Complete pressing step.
Final molding
By precompressed complete pipe fitting 13 be put into final molding lower impressions 10, by final molding upper impression 9 accord with shape molding at
For final molding chamber；The tube expansion hydraulic cylinder 11 of final molding chamber side pushes swollen head 15 to move in swollen head positioning sleeve 14,
Tube expansion is carried out to pipe fitting 13；That is is swollen, and head positioning sleeve 14 drives swollen head 15 to carry out tube expansion operation.
The final molding chamber and the draw hydraulic cylinder 12 of 11 opposite side of tube expansion hydraulic cylinder setting push drop-head 17 to exist
It is moved in drop-head positioning sleeve 16, the draw is carried out to pipe fitting 13.I.e. drop-head positioning sleeve 16 drives drop-head 17 to carry out necking operation.
Two oil cylinders of tube expansion hydraulic cylinder 11 and draw hydraulic cylinder 12 simultaneously operation, is completed at the same time tube expansion and the draw.It is hydraulic
After machine die sinking, a finished product pipe fitting is just completed the process.
Pre-molding and final molding step can carry out simultaneously in the present invention, in pipe fitting processing, if there is
Any size problem can adjust in time, greatly reduce the probability reprocessed and occurred with waste product.Preforming, guarantee pipe is carried out first
The molding final size of part and appearance are made on a secondary mould bases with molding preforming, realize that precompressed and final molding line are raw
It produces, guarantees that quality is stablized, improve production efficiency.Pre-pressing die may be implemented individually quickly to adjust.
The present invention can carry out precompressed to the different location of the pipe fitting of identical caliber by replacement locating piece position, and replacement is not
The precompressed of the pipe fitting of different tube diameters can also be carried out with diameter and specification pre-molding chamber.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art within the technical scope of the present disclosure, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
