Description
Technical field
The utility model relates to a kind of novel connection and draws the swollen header structure of expander roll, belongs to expander roll, swollen head technical field.
Background technology
Radiating tube many employings cold-drawn pipe of pipe type water radiator or elliptical tube, there is the area of dissipation of unit mass and the low problem of radiating efficiency, after adopting Novel special-shaped radiating tube, area of dissipation and the efficiency of unit mass greatly improve, but simultaneously also there is more strict requirement to the production Technology of this type of radiator, adopted and traditional push away the production requirement that expander roll and swollen head technique technology all can not reach Novel special-shaped radiating tube.
Chinese Patent Application No. 201320425082.5 discloses draws the swollen header structure of expander roll a kind of connection, this structure needs to connect expander roll at two ends simultaneously, interface occurs two, the whole so fit overall length of the swollen head group of expander roll of drawing reaches more than 2 meters, cause the increase of cost, draw the pulling force of expander roll very large in production process, increasing of interface increases to the production requirement of expander roll with regard to needing, and the reliability of the expander roll produced, stability are all poor, so processing technology requires also to need corresponding raising.
Summary of the invention
The purpose of this utility model is, a kind of novel connection is provided to draw the swollen header structure of expander roll, it not only solves to adopt and traditional pushes away expander roll and swollen head technique technology is difficult to solve the process issues drawing expander roll needed for expanded joint Novel special-shaped radiating tube, and saved cost and effort, also make reliability of the present utility model, stability obtains certain raising.
The technical solution of the utility model: the swollen header structure of expander roll is drawn in a kind of novel connection, comprise swollen head body, one end of swollen head body is provided with leader, the other end is provided with coupling part, a bossing is also provided with in the middle part of swollen head body, circular arc for caving inward in the middle of the two sides of bossing, this circular arc two is connected with semicircle spherical structure.
Aforesaid novel connection draws expander roll with in swollen header structure, and described leader comprises trapezium structure, trapezium structure is connected with blade arc structure.
Aforesaid novel connection draws expander roll with in swollen header structure, the radian r of the blade arc structure on described leader is: 3 ~ 5mm, the radian R of the circular arc on bossing is: 16.00 ~ 17.50mm, minimum thickness L between two circular arcs is: 1.0 ~ 1.4mm, and the crown radius r of the semi-round ball structure of circular sliding slopes is: 0.8 ~ 1.2mm.
Aforesaid novel connection draws expander roll with in swollen header structure, the radian r of the blade arc structure on described leader is: 4mm, the radian R of the circular arc on bossing is: 16.88mm, minimum thickness L between two circular arcs is: 1.2mm, and the crown radius r of the semi-round ball structure of circular sliding slopes is: 0.95mm.
Compared with prior art, swollen head is welded on the coupling part of expander roll body by the utility model, not only solve to adopt and traditional push away expander roll and swollen head technique technology is difficult to solve the process issues drawing expander roll needed for expanded joint Novel special-shaped radiating tube, and draw expander roll only need at one end connect swollen header structure, the swollen head group zoarium of expander roll is drawn to only have more than 1 meter, its production technology does not but change, on the basis of saving cost and effort, reliability and stability are also made to be improved accordingly, welding production is utilized to become this assembly, the processing technology of whole production process is made to become simple.

Detailed description of the invention
Embodiment.The swollen header structure of expander roll is drawn in a kind of novel connection, form as shown in Figure 1, Figure 2, Figure 3 and Figure 4, comprise swollen head body 1, one end of swollen head body 1 is provided with leader 2, the other end is provided with coupling part 4, also be provided with a bossing 3 in the middle part of swollen head body 1, the circular arc 5 for caving inward in the middle of the two sides of bossing 3, this circular arc 5 two is connected with semicircle spherical structure 6.
Described leader 2 comprises trapezium structure 7, trapezium structure 7 is connected with blade arc structure 8.The top view of described blade arc structure is arc-shaped, its front end be blade gradually to trapezium structure transitional structure, side view is the shape that circular arc is connected with circular cone.
The radian r of the blade arc structure 8 on described leader 2 is: 3 ~ 5mm, the radian R of the circular arc 5 on bossing 3 is: 16.00 ~ 17.50mm, minimum thickness L between two circular arcs 5 is: 1.0 ~ 1.4mm, and the crown radius r of the semi-round ball structure 6 that circular arc 5 connects is: 0.8 ~ 1.2mm.
The radian r of the blade arc structure 8 on described leader 2 is: 4mm, and the radian R of the circular arc 5 on bossing 3 is: 16.88mm, and the minimum thickness L between two circular arcs 5 is: 1.2mm, and the crown radius r of the semi-round ball structure 6 that circular arc 5 connects is: 0.95mm.
Make this when drawing the swollen head group of expander roll fit, first produce 1 swollen head body 1 and 1 draw expander roll 11, after monomer completes, adopt special fixture 2 single part weld (silver-bearing copper soldering) integral.
Utility model works principle as shown in Figure 4, draw on swollen baffle plate 10 by treating that the radiating tube 9 of expanded joint is fixed on, the expander roll 11 that draws be welded on swollen head body 1 passes the inside of radiating tube 9, pull one end pulling mouth contrary with swollen head locality on expander roll 11, the whole swollen head group zoarium of expander roll that draws is travelled forward, in motion process, radiating tube 9 dilates by the effect of the intermediate raised portion 3 that radiating tube 9 is subject on swollen head body 1.After the expansion processes of whole radiating tube 9 completes, take out radiating tube 9, pull the pulling mouth identical with swollen head locality, the whole swollen head group zoarium of expander roll that draws is resetted.
