Description
Technical field
The utility model relates to a kind of instrument, in particular, relates to a kind of practical expander head.
Background technology
At present, refrigeration and development of air conditioning industry rapid, tubing application wherein constantly expands, because tubing has different sizes, usually welding is adopted to connect therebetween, but for same caliber tubing between connection often a segment pipe is carried out expanding rear socket weld, therefore expander parts obtain good utilization.
At present, traditional expander parts often can only carry out expanding to a kind of tubing of caliber, and easy expander mechanism often can only carry out expanding to pipe with small pipe diameter, and expander parts substantially integrated being unfavorable for is changed and maintenance.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provide a kind of can according to actual needs by expanding for the tubing of the caliber of the same race tubing for different size, expander head easy to use.
The technical scheme adopted for realizing the purpose of this utility model is:
A kind of practical expander head, comprise fixed head, the head that rises, expand cover assembly and rotating shaft, described expansion cover assembly overlaps unit by multiple expansion and forms, each described expansion nest plate and connecting base plate expanding cover unit and comprise one, multiple described expansion nest plate expanding cover unit surrounds circumference, and described connecting base plate is provided with bolt hole; Described fixed head is provided with circular groove, the center of described circular groove is provided with a via hole that rises, multiple adjustment connecting hole is provided with in described circular groove, movable bolt is each passed through corresponding described bolt hole and is connected described expansion cover unit and fixed head with adjustment connecting hole, described fixed head is provided with and is fixedly connected with hole, described in the via hole that rises risen on circumference and described fixed head that first end surrounds through described expansion nest plate be connected with described drive shaft screw thread; The subtended angle of the described head that rises is identical with the circumference subtended angle that described expansion nest plate surrounds; Be disposed radially the space of automatic movable between described connecting base plate and groove, described connecting base plate drives described expansion nest plate radially to move.
Described expansion nest plate is eight.
Described adjustment connecting hole is the elongated hole along described circular groove radial direction.
Compared with prior art, the beneficial effects of the utility model are:
1, practical expander head of the present utility model controls the expanding size of tubing by the length of the distance of swollen head movement backward, thus make expander head of the present utility model can according to actual needs by expanding for the tubing of the caliber of the same race tubing for different size, easy to use.
2, practical expander head of the present utility model is owing to can design different swollen area of beds, the swollen head of a size can carry out expanding to the tubing of several size within the specific limits, thus makes expander head of the present utility model can carry out designing according to different calibers the expander head being processed into different tube diameters.
3, all adopt detachable connection due to all parts in practical expander head of the present utility model or fix, therefore changing conveniently; The expanding of the tubing of different tube diameters is carried out for can not can change this kind of expander head with the expanding tubing that the swollen head of same size carries out.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The schematic diagram of practical expander head of the present utility model as Figure 1-Figure 5, comprise fixed head 4, rise 1, expand cover assembly 2 and rotating shaft, described expansion cover assembly overlaps unit by multiple expansion and forms, each described expansion nest plate 7 and connecting base plate 8 expanding cover unit and comprise one, in the present embodiment, described expansion nest plate is eight.Multiple described expansion nest plate 7 expanding cover unit surrounds circumference, and described connecting base plate 8 is provided with bolt hole 9; Described fixed head is provided with circular groove 10, the center of described circular groove 10 is provided with the via hole 12 that rises, multiple adjustment connecting hole 11 is provided with in described circular groove 10, movable bolt 5 is each passed through corresponding described bolt hole 9 and is connected described expansion cover unit and fixed head 4 with adjustment connecting hole 11, described fixed head 4 is provided with and is fixedly connected with hole 3, described in rise circumference that 1 one end surrounds through described expansion nest plate 7 and described in the via hole 12 that rises be connected with described drive shaft screw thread.Described rise 1 subtended angle identical with the circumference subtended angle that described expansion nest plate 7 surrounds.Be disposed radially the space 6 of automatic movable between described connecting base plate 8 and circular groove 10, described connecting base plate 8 drives described expansion nest plate 7 radially to move.
Described adjustment connecting hole 11 is the elongated hole along described circular groove 10 radial direction.
During use, by fixed head by being fixedly connected with workbench through the described bolt being fixedly connected with hole.Being placed on to expand by the circumferential concentric that tubing and expansion nest plate are formed overlaps outside assembly 2 and swollen 1, rotate rotating shaft, make to expand cover assembly outward movment by the motion backward of swollen 1, pipe internal diameter is expanded gradually, expand cover assembly 2 by movable bolt 5 motion in adjustment connecting hole 13 simultaneously, the displacement of swollen 1 can be changed according to demand to control the finally expanding of tubing, when the movable bolt 5 expanding the connection of cover assembly 2 radially moves to adjustment connecting hole 11 outermost end, now complete the maximum expanding of tubing.
Novel expander head of the present utility model adopts abrasion-resistant stee to process, the expanding size of tubing can be controlled by the length of the distance of swollen head movement backward, make expander head of the present utility model can according to actual needs by expanding for the tubing of the caliber of the same race tubing for different size.
Novel expander head of the present utility model is owing to can design different swollen area of beds, and the swollen head of a size can carry out expanding to the tubing of several size within the specific limits, therefore, can carry out designing the expander head being processed into different tube diameters according to different calibers.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
