Abstract
The invention relates to a thrust type pipe expander which comprises an expanding rod and an expanding shell connected to the head part of the expanding rod, wherein an expanding bead is arranged in the expanding shell, a small section of threads is arranged in the middle of the expanding rod, an adjusting nut is connected between one end of the threaded section and the middle part of the expanding shell, a limiting nut is connected to the other end of the threaded section, and the expanding shell can extend out of the head part of the expanding rod in the working process. When the expander is used for expanding a pipe with a tighter opening or a pipe internally provided with a blind hole, the expanding shell extends out of the expanding rod, the expanding bead can completely expand to the interior of the pipe to reach the bottom of the blind hole so as to expand the pipe completely.
Description
Technical field
The present invention relates to a kind of tube expander, especially relate to a kind of thrust formula tube expander that has the pipe swelling of blind hole at the mouth of pipe in the very short or pipe that uses.
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 that vertical being placed on of pearl level of adopt expanding expanded in the shell, and bloated shell can arbitrarily slide on expander roll, but for the pipe of blind hole or short mouthful, when expanded joint, bloated pearl can't reach the expanded joint position.
Summary of the invention
But technical problem to be solved by this invention provides the thrust formula tube expander that has blind hole in a kind of expanded joint short tube mouth or the pipe.
The present invention solves the technical scheme that its technical problem takes: a kind of thrust formula tube expander, comprise expander roll, be connected the bloated shell of expander roll head, in the shell that expands, the pearl of expanding is housed, offer a bit of screw thread in the centre of expander roll, be connected with adjusting nut in the middle of one end of screw thread and the bloated shell, the other end at screw thread is connected with stop nut, and shell extended expander roll head in the process of work expands.
For can the expanded joint blind hole or short mouthful pipe, the shell that expands be expanded in the blind hole by the adjusting of adjusting nut on screw thread.
In order to limit the degree of depth that the pearl of expanding enters pipe, the restriction nut can move on thread segment, promotes stop nut then backward.
After adopting said structure, when being the pipe of blind hole at the expansion mouth of pipe in the tighter or pipe, bloated shell stretches out expander roll, and bloated pearl can all be expanded in the inlet pipe, by the adjusting of adjusting nut on screw thread, reaches the bottom of blind hole, plays the effect of whole expansions.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is a stereogram of the present invention;
Schematic diagram when Fig. 2 is an expanded joint of the present invention;

The specific embodiment
Fig. 1, a kind of thrust formula tube expander shown in Figure 2, comprise expander roll 1, be connected the bloated shell 2 of expander roll 1 head, the pearl 3 of expanding is housed in bloated shell 2, offer a bit of screw thread 5 in the centre of expander roll 1, be connected with adjusting nut 4 in the middle of one end of screw thread 5 and the bloated shell 2, the other end at screw thread 5 is connected with stop nut 6, and shell 2 extended expander roll 1 head in the process of work expands.
When being the pipe of blind hole in the tighter or pipe of the expansion mouth of pipe, adjusting nut 4 moves on screw thread, promotes stop nut 6 backward, and the shell 2 that expands stretches out expander roll 1, and the pearl 3 of expanding can all be expanded in the inlet pipe, reaches the bottom of blind hole, plays the effect of whole expansions.
Claims (1)
