Abstract

The utility model relates to an expanding head device of a pipe expander, which comprises an expanding head seat arranged on a frame. A plurality of expanding heads capable of expanding elliptical copper pipes are sequentially arranged on the expanding head seat, each expanding head comprises two side-by-side round bars and conical expanding ball fasteners, the two round bars are arranged on the expanding head seat, the conical expanding ball fasteners are arranged at the lower ends of the two round bars, and elliptical expanding heads are arranged at ends of the round bars. The expanding head device overcomes the shortcomings of the prior art, and is simple in structure and fine in pipe expanding effect.

Description

A kind of expansion head unit of electric tube expander
[technical field]
The present invention relates to a kind of expansion head unit of electric tube expander.
[background technology]
Existing a kind of expansion head unit that oval copper pipe is enlarged is generally expanded copper pipe by the bloated head of bigger elliptical rod.But compare waste material like this, cost is high.
The present invention is just making in such cases.
[summary of the invention]
The present invention seeks to overcome deficiency of the prior art and a kind of simple in structure, expansion head unit that expander is effective is provided.
In order to solve the technical problem of above-mentioned existence, the present invention adopts following technical proposal:
A kind of expansion head unit of electric tube expander; Include the expansion headstock 1 that is located on the frame 3; Be disposed with a plurality of expansions that can oval copper pipe be enlarged 2 on the headstock 1 expanding; It is characterized in that described expansion 2 includes two and is arranged on the round bar side by side 21 that expands on the headstock 1 and the bloated ball fixtures 23 of the taper of the lower end that is located at these two round bars 21, be provided with in the end of round bar 21 and oval-shapedly expand 22.
The expansion head unit of aforesaid a kind of electric tube expander is characterized in that also including the multilayer guide plate 4 that is located on the frame 3, on the guide plate 4 of each layer, is provided with the through hole 41 of a plurality of guiding round bars 21 that match with round bar 21.
The expansion head unit of aforesaid a kind of electric tube expander, the number of plies that it is characterized in that said guide plate 4 is the 3-5 layer.
The present invention compared with prior art has following advantage:
The present invention utilizes two round bars side by side, is provided with the bloated head of taper in the lower end of two round bars, and a peripheral tangent line that expands just forms elliptical shape, utilizes oval bloated to expand copper pipe.Simple in structure, practicality, cost is low.

[specific embodiment]
Describe the present invention below in conjunction with accompanying drawing:
A kind of expansion head unit of electric tube expander includes the expansion headstock 1 that is located on the frame 3, is disposed with a plurality of expansions that can oval copper pipe be enlarged 2 on the headstock 1 expanding.Specifically, described expansion 2 includes two and is arranged on the round bar side by side 21 that expands on the headstock 1 and the bloated ball fixtures 23 of the taper of the lower end that is located at two round bars 21.Be provided with oval-shaped bloated 22 in the end of round bar 21.By bloated 22 oval copper pipe is enlarged.
Like this, earlier 22 expand and open oval copper pipe mouth by expanding, promote to expand headstock 1 by the drive unit on the electric tube expander afterwards and move down, expand headstock 1 and be with and expand 2 down movingly, the ball fixture 23 that expands 22 carries out expander with regard to getting into together with expanding in the copper pipe.Simply, practicality.
In addition, also include the multilayer guide plate 4 that is located on the frame 3, on the guide plate 4 of each layer, be provided with the through hole 41 of a plurality of guiding round bars 21 that match with round bar 21.Each root round bar 21 corresponding through hole 41 that pass.Like this, when expander, round bar 21 is not easy bending, guarantees service life.
As the optimal way of present embodiment, the number of plies of said guide plate 4 is the 3-5 layer.Generally confirm the number of plies of guide plate 4 according to the length of round bar 21.
