Abstract
The invention relates to a 90-degree flanging pipe expander, which comprises an expanding shell, an expanding bead arranged in the expanding shell and an expanding rod passing through the expanding shell, wherein the position of the middle of the expanding shell engaged with the expanding bead is provided with an edge pressing bead, the edge pressing bead is connected on the expanding shell by using a fixed bracket through nuts, and the edge pressing bead is in a shape that the middle is sunken. When the inside or outside diameter of a pipe is expanded, the expanding rod is propelled to drive the expanding bead to be screwed into the expanding shell; and when the edge port of the pipe reaches the edge pressing bead, because the middle of the edge pressing bead is sunken, the pipe orifice edge is bent to the edge along the sunken locus of the edge pressing bead, and then the pipe orifice can be expanded with 90 radians.
Description
Technical field
The present invention relates to a kind of tube expander, especially relate to a kind of 90 degree flange tube expanders that can spend mouth of pipe expansion for outward flanging 90 arcs.
Background technology
Tube expander be make, all kinds of containers of maintenance are to be used for the inside and outside footpath of enlarged pipe, are to combine closely in the tube-to-tube sheet connection contact site, can not leak, leak gas and can bear a kind of expanded joint instrument of certain pressure.At present, the tube expander that the expanded joint on the market is used all is to adopt vertical being placed in the bloated shell of the pearl level that expands, the groove of the trapezoidal pattern of the Eight characters in offering on the shell that expands, and the mouth of pipe of expansion all is into trumpet-shaped, can not reach the requirement that surpasses certain mouth of pipe expansion number of degrees.
Summary of the invention
Technical problem to be solved by this invention provides a kind of 90 degree flange tube expanders that can expand into the mouth of pipe definite shape as required.
The present invention solves the technical scheme that its technical problem takes: a kind of 90 degree flange tube expanders comprise bloated shell, are installed in the bloated pearl of the shell inside of expanding and pass the expander roll of the shell that expands that there is the flanging pearl position that is connected with bloated pearl in the centre of the shell that expands.
For when expanding the inside and outside footpath of pipe, prevent the flanging pearl owing to the pressure effect produces dislocation, described flanging pearl is connected on the shell that expands by nut with fixed support.
Become certain shape and meet the requirements of radian in order to expand the mouth of pipe, the shape of described flanging pearl is inner concave shape in the middle of being.
After adopting said structure, when the inside and outside footpath of enlarged pipe, advance expander roll, drive the pearl of expanding, the precession shell that expands, when pipe limit mouth arrives at the flanging pearl, fixed support can stop the flanging pearl owing to dislocation is out of shape in the effect of the power of being squeezed, because the centre of flanging pearl is an inner concavity, mouth of pipe edge can be along the indent track of flanging pearl to curved edge, like this, the mouth of pipe can be expanded into 90 degree radians.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a stereogram of the present invention;
Fig. 2 is the schematic diagram of flanging pearl;
1, bloated shell 2, bloated pearl 3, expander roll 4, flanging pearl 5, fixed support
The specific embodiment
A kind of 90 degree flange tube expanders shown in Figure 1, comprise the shell 1 that expands, be installed in the bloated pearl 2 of shell 1 inside of expanding and pass the expander roll 3 of the shell 1 that expands, there is flanging pearl 4 centre at the shell 1 that expands with the position that bloated pearl 2 is connected, described flanging pearl 4 is to be connected on the shell 1 that expands by nut with fixed support 5, and fixed support 5 can stop that flanging pearl 4 is owing to dislocation is out of shape in the effect of the power of being squeezed.
The shape of flanging pearl 4 shown in Figure 2 be in the middle of for inner concave shape, mouth of pipe edge can be along the indent track of flanging pearl 4 to curved edge, like this, the mouth of pipe can be expanded into 90 degree radians.
When the inside and outside footpath of enlarged pipe, advance expander roll 3, drive the pearl 2 of expanding, the precession shell 1 that expands, when pipe limit mouth arrived at the flanging pearl, fixed support 5 can stop that flanging pearl 4 is owing to dislocation is out of shape in the effect of the power of being squeezed, because the centre of flanging pearl 4 is an inner concavity, mouth of pipe edge can be along the indent track of flanging pearl 4 to curved edge, and like this, the mouth of pipe can be expanded into 90 degree radians.
