1. trouble is installed.Volume, the weight of the left side of the structure that is connected as a single entity sealing core print, core bar, right sealing core print are bigger, insert time-consuming, the effort of multiple tube inner tube, especially work as the multiple tube of being processed when longer, and this Unit Installation is trouble more just.
2. sealing property is difficult to guarantee.
For just with installation, fixing ring adopted is the sealing ring that material itself (non-structure) can produce the radial displacement distortion, and this kind sealing ring also is easy to generate distortion under the high pressure effect of liquid, influence its sealing effectiveness.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, and a kind of composited tube hydraulic forming device of easy for installation, good sealing effect is provided.
Technical solution of the present utility model is: a kind of composited tube hydraulic forming device, left side sealing core print 1, right sealing core print 2 are arranged, in left side sealing core print 1, right sealing core print 2, be respectively equipped with hydraulic pressure water inlet 3, air exit 4, the outside at left side sealing core print 1, right sealing core print 2 is respectively equipped with sealing ring 5,6, be respectively equipped with the medium channel 7,8 that communicates with sealing ring 5,6 inner chambers in left side sealing core print 1, right sealing core print 2, described left sealing core print 1, right sealing core print 2 separate setting; Described sealing ring 5,6 is the corrugated sealing ring, the front end of sealing ring 5,6 is fixed on left side sealing core print 1, the right sealing core print 2, the rear end is fixed on the sealing sliding sleeve 9,10, sealing sliding sleeve 9,10 slips respectively on left side sealing core print 1, right sealing core print 2, outside left side sealing core print 1, right sealing core print 2, also be socketed with and seal the fixture 11,12 that sliding sleeve 9,10 joins respectively, between fixture 11,12, be provided with cylinder lever connecting rod 13, be respectively equipped with the preceding seam 14,15 of sealing sliding sleeve 9,10 on the described sealing core print 1,2.
The material of described corrugated sealing ring is a fluorosioloxane rubber.
The left side of this device sealing core print, right sealing core print separate and are provided with, and the pull bar of opposing axial hydraulic power is installed on fixture, during installation, only a left side are sealed core print, right sealing core print and seal thereof and insert and get final product in the multiple tube inner tube; Especially sealing ring is the corrugated sealing ring and can be enclosed within left side sealing core print, the slip of right sealing core print with sealed sliding, can be at it and insert easily under extended state in the multiple tube inner tube, installs very convenient.During sealing, the corrugated sealing ring can move and is in compressive state with the sealing sliding sleeve, the convergent force of corrugated sealing ring with and the expansive force of inner chamber pressure medium, can guarantee when multiple tube takes place to enlarge because of the hydraulic buckling radial dimension, continue to combine closely, reach good sealing effectiveness with the multiple tube inwall.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
