Abstract
The utility model discloses a device for expander constitutes by installing the body, the device body includes the oil storage jar, oil storage jar one side upper end is connected with manual hydraulic pressure pipe, oil storage jar one side lower extreme is connected with high pressure fuel pipe, the high pressure fuel pipe lower extreme is connected with the hole ware that rises, it is provided with four at least evenly distributed's expander post on the ware outer wall of hole to rise. The utility model discloses simple structure, sleeve pipe preparation high quality to the poor problem of its manufacturing method efficiency has been solved.
Description
Technical field
The utility model relates to a kind of sleeve pipe producing device, especially relates to a kind of device for sleeve pipe expander.
Background technology
Often use tube and tube in on-the-spot real work and link sleeve pipe used.The method making sleeve pipe has two kinds at present.One is processed with lathe, but cost is higher; One is that oneself makes at the scene, and existing preparation method cost is low but efficiency is poor.Concrete preparation method is as follows: 1) steel pipe is cut out the pipeline section 2 that length is 2 times of diameters) the one side sanding machine of pipeline section is cut out straight line 3) pipeline section after cutting is overlapped by force and gets back on steel pipe, be that the mouth spreading of cutting is to moving on steel pipe easily.
Utility model content
The purpose of this utility model overcomes deficiency of the prior art, provides that a kind of structure is simple, easy to operate, sleeve pipe quality and the high device for sleeve pipe expander of make efficiency.
In order to solve the problems of the technologies described above, the utility model provides a kind of device for expander, be made up of device body, described device body comprises oil storage cylinder, upper end, described oil storage cylinder side is connected with hand-hydraulic pipe, lower end, described oil storage cylinder side is connected with high-pressure oil pipe, and described high-pressure oil pipe lower end is connected with the hole device that rises, described in rise on the device outer wall of hole and be provided with at least four equally distributed expander posts.
The described hole device that rises is that tubular structure is formed.
The beneficial effects of the utility model are: the utility model adopts the hole device outer wall that rises to arrange expander post, and use hydraulic means to make expander capital go out to rise outside the wall of hole to the hole device injection oil that rises, until pipe end spreading is to required size, structure is simple, easy to operate, change original method making sleeve pipe at the scene, improve the quality and efficiency that make.
Accompanying drawing explanation
Fig. 1: the utility model apparatus structure schematic diagram.
Accompanying drawing marks: 1, oil storage cylinder; 2, hand-hydraulic pipe; 3, high-pressure oil pipe; 4, rise hole device; 5, expander post.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, a kind of device for expander, be made up of device body, described device body comprises oil storage cylinder 1, upper end, described oil storage cylinder 1 side is connected with hand-hydraulic pipe 2, and lower end, described oil storage cylinder 1 side is connected with high-pressure oil pipe 3, and described high-pressure oil pipe 3 lower end is connected with the hole device 4 that rises, the described hole device 4 that rises is formed for tubular structure, described in rise on hole device 4 outer wall and be provided with at least four equally distributed expander posts 5.
Make use of the device for expander described above carries out expander method to sleeve pipe, comprise the steps: first.Preparation is as above for the device of expander; Secondly, steel pipe is cut out the pipe end that length is at least twice diameter of steel tube, and described pipe end one side is cut out straight line; Then, being enclosed within by the pipe end of well cutting rises on hole device 4, and press hand-hydraulic pipe 2 and pressurize to oil storage cylinder 1, now, oil in oil storage cylinder 1 flows to by high-pressure oil pipe 3 the hole device 4 that rises, and equally distributed expander post 5 ejects and rises outside hole device 4 outer wall on hole device 4 outer wall that will rise, by pipe end spreading to required size.
Claims (2)
1. the device for expander, be made up of device body, it is characterized in that, described device body comprises oil storage cylinder, upper end, described oil storage cylinder side is connected with hand-hydraulic pipe, lower end, described oil storage cylinder side is connected with high-pressure oil pipe, and described high-pressure oil pipe lower end is connected with the hole device that rises, described in rise on the device outer wall of hole and be provided with at least four equally distributed expander posts.
2. the device for expander according to claim 1, is characterized in that, described in rise hole device be tubular structure form.
