Description
Technical Field
The utility model relates to an expander field, in particular to expander support body structure.
Background
The air conditioner compressor shell is inevitably applied to a round pipe in the manufacturing process, and the diameter treatment of the round pipe is generally realized by a pipe expanding mode.
The mode of current expander adopts the toper fore-set to expand the pipe more, and the expander only need through the hydro-cylinder carry out lifting control to the toper fore-set can to, the expander of this kind of mode is fixed a position the pipe mostly, and this kind of mode is lower to the requirement of expander support body, but the expander effect is short of, and, there is the pipe wall in the expander in-process in the toper fore-set and supports the problem of lacking.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned problem, provide a pipe expander support body structure, overall structure is succinct, low in production cost, and the practicality is strong, through the location to concatenation formula pipe expander mould, realizes the expander, has solved the poor problem of traditional toper fore-set expander to the pipe wall support nature.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a pipe expander support body structure, includes the support body, and this support body upside is equipped with the pipe expanding platform, and pipe expanding platform central point puts and is equipped with circular shape fore-set through-hole, and the fore-set through-hole is equipped with the spacing arch of multichannel slider at its circumference side equipartition, and the spacing arch of slider sets up the diametric at the fore-set through-hole, and the fore-set through-hole outside is concentric to be fixed with the lid, and the lid middle part is equipped with circular channel groove, and this circular channel groove diameter is greater than fore-set through-hole diameter.
Furthermore, the cover body is provided with a step free end for limiting the spliced pipe expanding die.
Further, the number of the limiting protrusions of the sliding block is 6.
Furthermore, a plurality of fixing through holes are formed in the pipe expanding platform on two sides of the top column through hole in parallel.
To sum up, the utility model discloses possess following advantage:
the utility model discloses overall structure is succinct, low in production cost, and the practicality is strong, through the location to concatenation formula expand tube mould, realizes the expander, has solved the poor problem of traditional toper fore-set expander to the pipe wall support nature.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a top view of the pipe expanding platform of the present invention;
fig. 3 is a schematic view of the arrangement of the cover body and the tube expansion die.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
example 1:
a frame body structure of a pipe expander, as shown in fig. 1-3, comprises a frame body 1.
The pipe expanding platform 11 is arranged on the upper side of the support body 1, the circular ejection column through hole 12 is formed in the center of the pipe expanding platform 11, the ejection column through hole 12 is used for connecting the ejection column with an oil cylinder arranged on the lower side of the support body 1, and the ejection column penetrates through the ejection column through hole 12 to be connected with the oil cylinder.
The fore-set through-hole 12 is equipped with spacing arch 13 of multichannel slider at its circumference side equipartition, and this spacing arch 13 of slider sets up the diameter direction at fore-set through-hole 12, and this spacing arch 13 of slider can be connected with the expand tube mould bottom side spout of concatenation formula to the fore-set during operation, the concatenation formula expand tube mould that sets up in the fore-set outside can be along the spacing arch 13 motion of this slider, thereby realizes the function of expand tube.
Meanwhile, a cover body 2 is concentrically fixed on the outer side of the top column through hole 12, a circular channel groove 21 is formed in the middle of the cover body 2, and the diameter of the circular channel groove 21 is larger than that of the top column through hole 12.
The circular channel groove 21 is arranged at the central position, and particularly, the circular channel groove and the top pillar through hole 12 are of a concentric circle structure, so that the whole vertical movement of the top pillar can be ensured to be collinear with the axis of the channel.
With further reference to fig. 3, the diameter of the circular channel 21 is also greater than the diameter of the expansion die, i.e. leaving an expanded dimension to the round tube.
Moreover, the cover body 2 is provided with a step suspension end 22 for limiting the spliced pipe expansion die, so that the pipe expansion die moves along the slide block limiting bulge 13, the pipe expansion of the round pipe sleeved outside the pipe expansion die is realized, and the round pipe is prevented from moving together with the jacking column.
Preferably, the number of the slide block limiting protrusions 13 is 6, and the number of the slide blocks is equal to that of the sub-dies which are specifically equally divided by the splicing type pipe expanding die.
And a plurality of fixing through holes 14 are arranged on the pipe expanding platform 11 in parallel on two sides of the top column through hole 12 and are used for fixing power components such as oil cylinders or oil cylinder stroke distance measuring components on the frame body.
