Abstract
The invention relates to a rive-ball precision deep hole pipe expander which comprises an expansion rod, an expansion shell, expansion balls and a slender expansion rod capable of extending out, wherein the expansion shell is connected to the expansion rod; the expansion balls are loaded in the expansion shell; the slender expansion rod capable of extending out is connected to the inner cavity of the expansion rod and can be stretched along the inner cavity of the upper expansion rod; and the number of the expansion balls is five. In the process of the expansion of a thin-wall pipe of a heat exchanger on nuclear power equipment or the quick and precise expansion of the pipe on a composite pipe plate and a stainless steel plate having high requirements, because the inner diameter of the pipe is small, the inner part of a hole is deeper, the slender expansion rod can be extended out along the inner part of the expansion rod; and when the pipe port is expanded, because five expansion balls are arranged in the expansion shell, the inner diameter of the expanded pipe is round and smooth and has high precision.
Description
Technical field
The present invention relates to a kind of tube expander, but especially relate to a kind of expanded joint deep hole and guarantee ips rounding, smooth five pearl precision deep hole tube expanders.
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 expanded joint on the market is used, all be 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 bloated shell, when the precession tube interior, can produce bigger resistance, and, because the interior hole depth of expanded joint pipe is longer, can contract after making tube expander because of the toughness of tubing, the words of exerting oneself excessive can might be burst the critical point.
Summary of the invention
But technical problem to be solved by this invention provides a kind of expanded joint deep hole and guarantees ips rounding, smooth five pearl precision deep hole tube expanders.
The present invention solves the technical scheme that its technical problem takes: a kind of five pearl precision deep hole tube expanders, comprise expander roll, and be connected the bloated shell on the expander roll, the bloated pearl of shell inside of expanding of packing into connects an exsertile elongated expander roll in the inner chamber peace of expander roll.
The pipe little for energy expanded joint spout diameter and hole depth is very big, described elongated expander roll are can be flexible along the inner chamber of top expander roll.
In order to guarantee the back ips rounding, smooth that expands, the number of described bloated pearl is five.
After adopting said structure, on the expanded joint nuclear power generating equipment on the light-wall pipe of heat exchanger or demanding clad tubesheet, the corrosion resistant plate fast with expand tube accurately the time, because ips is little, inside, hole is darker, can go out elongated expander roll along the inner tensile of expander roll, during the expanded joint mouth of pipe, the bloated pearl in the shell that expands is five, the back ips rounding that expands, smooth, precision is high.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a front view of the present invention;
1, expander roll 2, the shell 3 that expands, bloated pearl 11, elongated expander roll
The specific embodiment
A kind of five pearl precision deep hole tube expanders shown in Figure 1, comprise expander roll 1, be connected the bloated shell 2 on the expander roll, the bloated pearl 3 of shell inside of expanding of packing into connects an exsertile elongated expander roll 11 in the inner chamber peace of expander roll, and described elongated expander roll 11 is can be flexible along the inner chamber of top expander roll, effect is to guarantee the darker pipe of expanded joint endoporus, the number of described bloated pearl 3 is five, behind expanded joint, has guaranteed the smoothness of the mouth of pipe.
On the expanded joint nuclear power generating equipment on the light-wall pipe of heat exchanger or demanding clad tubesheet, the corrosion resistant plate fast with expand tube accurately the time, because ips is little, inside, hole is darker, can go out elongated expander roll 11 along the inner tensile of expander roll 1, during the expanded joint mouth of pipe, the bloated pearls 3 of expanding in the shell 2 are five, the back ips rounding that expands, smooth, precision is high.
Claims (3)
1. a pearl precision deep hole tube expander comprises expander roll (1), is connected the bloated shell (2) on the expander roll, and the bloated pearl (3) of the bloated shell inside of packing into is characterized in that: the inner chamber peace at expander roll (1) connecing an exsertile elongated expander roll (11).
2. according to right 1 described five pearl precision deep hole tube expanders, it is characterized in that: described elongated expander roll (11) is can be flexible along the inner chamber of top expander roll.
