Abstract
The utility model discloses a kind of elliptical tube tube and carry effect device, comprise the head and to rise bar of rising, described in the first end that rises be fixedly mounted on and rise on boom end, described in rise the head ovalize of head, the major axis of described ellipse is 750-850mm, and minor axis is 220-280mm.Oval tube of the present utility model is not easily broken, can be once-forming, can save many power, improves the ductility of tube, keeps the in the same size of each mouth of pipe.
Description
Technical field
The utility model is specifically related to a kind of elliptical tube tube and carries effect device.
Background technology
Air-condition heat exchanger heat exchange copper tube, in order to be connected with other pipeline component, needs the end of heat exchanging copper pipe to expand usually, forms horn mouth, is convenient to heat exchange copper tube to be crimped on other pipeline component.Generally tube-expanding device of air-condition heat exchanger is adopted to the expansion of copper pipe.
Oval tube heat exchanger because of front face area little, energy-saving effect is obvious, and applying technique country in the world is the earliest Japanese Mitsubishi Heavy Industries Ltd.And the ultrathin type of aluminium foil fin due to elliptical tube, the uneven deformation of position, modification hole, adds the sex change difference of oval copper pipe, before not improving, in production operation process, easily occurs dew copper, diagonal deviation.Copper pipe not easily passes etc. does over again and copper material wasting phenomenon, inefficiency.And the control of the thrust of tube is more difficult, tube is easily broken.
In the progradation of tube, the resistance that tube is subject to advances the increase of the degree of depth along with it and increases progressively, and the length so just determining tube is unsuitable long, may need could be shaped through secondary tube.
Utility model content
Utility model object: in order to solve the deficiencies in the prior art, the utility model provides a kind of elliptical tube tube and carries effect device, can be once-forming, can save many power, improves the ductility of tube, keeps the in the same size of each mouth of pipe.
Technical scheme: a kind of elliptical tube tube carries effect device, comprises the head and to rise bar of rising, described in the first end that rises be fixedly mounted on and rise on boom end, described in rise the head ovalize of head, the major axis of described ellipse is 750-850mm, and minor axis is 220-280mm.
As optimization: described in the boom end that rises be provided with installing hole, the first end that rises inserts in installing hole.
As optimization: described in the first end that rises be provided with connecting hole, the end of the bar that rises described in described connecting hole is sleeved on.
Beneficial effect: oval tube of the present utility model is not easily broken, can be once-forming, can save many power, improves the ductility of tube, keeps the in the same size of each mouth of pipe.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A cross section structure schematic diagram of the present utility model;
Fig. 3 is the close-up schematic view of Fig. 2 in the utility model;
Fig. 4 is a schematic cross-section that rises of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
Embodiment
As Figure 1-4, a kind of elliptical tube tube carries effect device, comprises rise 1 and the bar 2 that rises, described in 1 one end of rising be fixedly mounted on and rise on bar 2 end, described in rise 1 head ovalize, the major axis of described ellipse is 750-850mm, and minor axis is 220-280mm.Described bar 2 end of rising is provided with installing hole, and 1 one end of rising is inserted in installing hole.Described 1 one end of rising is provided with connecting hole, the end of the bar 2 that rises described in described connecting hole is sleeved on.
Oval tube of the present utility model is not easily broken, can be once-forming, can save many power, improves the ductility of tube, keeps the in the same size of each mouth of pipe.
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.
