Utility model content
The purpose of this utility model is that solve the above-mentioned problems and designs a kind of hydraulic tube expander of the present invention.
Specific technical solution is as follows：It includes support rod and four spreading mechanisms, and the support rod is cuboid, four institutes
Spreading mechanism is stated to be located on four sides of support rod and be axially arranged along support rod.
Further, each spreading mechanism includes support frame and three hydraulic stems, three hydraulic stem intervals
It is uniformly arranged on outside support rod and each hydraulic stem bottom and support rod is articulated and connected, support frame as described above is located at three hydraulic stems
Top.
Further, support frame as described above includes support plate and two fixed plates, the support plate be it is arc-shaped, it is described two
Fixed plate is fixed on interval setting below support plate, the output section of each hydraulic stem be respectively positioned between two fixed plates and with
Two fixed plate articulated connections.
Further, each hydraulic stem two sides are respectively arranged with slide post, are provided with slide rail on the outside of the slide post, described
Slide rail bottom is provided with positioning seat, and the positioning seat is fixed on the outside of support rod.
Further, it is machined with external screw thread on the outside of the slide post, is provided with location nut on the outside of the slide post, it is described
Location nut is threadedly coupled with slide post.
Beneficial effect is：The utility model substitutes mechanical mechanism using hydraulic mechanism, and when use puts the utility model
It sets inside pipe, pipe can be strutted by then starting hydraulic pump, eliminate manual operation, and use process is simpler, work
More efficient, for strutting various sizes of pipe, angle between adjustable hydraulic stem and support rod is practical to control
Novel struts diameter, and the scope of application is wider.

Specific embodiment
Such as Fig. 1 and Fig. 2, a kind of hydraulic tube expander comprising support rod 2 and four spreading mechanisms 1, support rod 2 are rectangular
Body, four spreading mechanisms 1 are located on 2 four sides of support rod and along the axial settings of support rod 2, and spreading mechanism 1 can support
Open pipe base can strut simultaneously pipe using four spreading mechanisms 1 with four direction, guarantee pipe uniform force when being softened.
Each spreading mechanism 1 includes support frame 11 and three hydraulic stems 12, and hydraulic stem 12 is power output, and three hydraulic
The interval of bar 12 is uniformly arranged on the outside of support rod 2 and 12 bottom of each hydraulic stem and support rod 2 are articulated and connected, i.e., hydraulic stem 12 with
Adjustable angle between support rod 2, angle is smaller between hydraulic stem 12 and support rod 2, the distance between support frame 11 and support rod 2
Closer, support frame 11 is located at three hydraulic stems, 12 top, i.e., each support frame 11 is propped up by three hydraulic stems 12.
Support frame 11 include support plate 111 and two fixed plates 112, support plate 111 be it is arc-shaped, it is arc-shaped to be more advantageous to
It is bonded tube blank inner wall, two fixed plates 112, which are fixed below support plate 111, is spaced setting, the output section 121 of each hydraulic stem 12
It is respectively positioned between two fixed plates 112 and is articulated and connected with two fixed plates 112, articulated connection is convenient for adjusting hydraulic stem 12 and branch
Angle between support 11.
Each 12 two sides of hydraulic stem are respectively arranged with slide post 122, slide rail 124 are provided on the outside of slide post 122, sliding is led
124 bottom of rail is provided with positioning seat 125, and positioning seat 125 is fixed on 2 outside of support rod, is machined with outer spiral shell on the outside of slide post 122
Line is provided with location nut 123 on the outside of slide post 122, and location nut 123 is threadedly coupled with slide post 122, adjusts hydraulic stem 12
When angle between support rod 2, with the rotation of hydraulic stem 12, slide post 122 is moved along sliding rail, when angle adjust to
When suitable, rotational positioning nut 123 makes hydraulic stem 12 and location nut 123 clamp slide rail 124 to fixer compression bar 12
Position, then the work of external hydraulic pump control hydraulic stem 12 is to strut pipe.
Lower mask body introduces the course of work of the utility model：In use, the external hydraulic pump of hydraulic stem 12, first measures
Then tube blank size adjusts the distance between hydraulic stem 12 and support rod 2, is put into the utility model smoothly in pipe
Portion, then 123 fixer compression bar of screwed in place nut, 12 position, the utility model is put into inside pipe, starts hydraulic pump control
The elongation of hydraulic stem 12 processed struts pipe, and pipe controls hydraulic pump again and shrinks hydraulic stem 12 after strutting, and reversely rotates location nut
123, then rotating hydraulic bar 12 shrinks spreading mechanism 1.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
