Abstract
The utility model discloses the swollen mouth frock of a kind of radiating tube, belong to the mouth of pipe and dilate frock; Aim to provide a kind ofly guarantee orifice configuration and dimensional accuracy, the mouth of pipe that efficiency is high dilates frock.It by being fixed on the expander roll (3) of the body of rod (4) termination, the transition expander roll (2) being fixed on this expander roll front end, the guide head (1) that is fixed on this transition expander roll front end form; The left and right sides of expander roll (3) are the flat-shaped structure of milling, upper and lower side is convex structure, and transition expander roll (2) is flat pyramidal structure, and guide head (1) is for front end is with meniscate flat scoop structure.The utility model can ensure that transition expander roll inserts gradually smoothly and realize the mouth of pipe in closing waist type radiating tube and dilate, and expanding is very convenient.
Description
Technical field
The utility model relates to the swollen mouth frock of a kind of radiating tube, particularly relates to a kind of frock for dilating the closing waist type radiating tube mouth of pipe.
Background technology
Radiating tube is the important spare part of radiator, and its heat dispersion depends primarily on the contact area of radiating tube inwall and fluid; At present, the shape of radiating tube mainly contains pipe, elliptical tube and elliptical tube etc.Along with the high speed development of auto industry, also come higher to the volume of radiator and thermal diffusivity efficiency requirements, the radiating tube of traditional structure can not expire automobile industry development requirement; For this reason a kind of cross section be the figure of eight or peanut shape closing waist type radiating tube in response to and give birth to.
In order to prevent radiating tube in assembling process to be drawn out heat radiation core body, usually need to carry out enlarging shaping to the radiating tube mouth of pipe.Because the structure of closing waist type radiating tube is comparatively complicated, common flaring tooling is difficult to meet the demands.
Summary of the invention
In order to overcome the defect existed in prior art, the utility model aims to provide the swollen mouth frock of a kind of radiating tube, utilize the mouth of pipe of this frock to closing waist type radiating tube to carry out swollen mouth shaping, can not only guarantee that orifice configuration and dimensional accuracy reach designing requirement, and efficiency is high.
To achieve these goals, the utility model is by the following technical solutions: it by being fixed on the expander roll of body of rod termination, the transition expander roll being fixed on this expander roll front end, the guide head that is fixed on this transition expander roll front end form; The left and right sides of expander roll are the flat-shaped structure of milling, upper and lower side is convex structure, and transition expander roll is flat pyramidal structure, and guide head is that front end is with meniscate flat scoop structure.
Compared with the prior art, the utility model is owing to have employed technique scheme, by the guiding of front end with meniscate flat spade guide head, transition expander roll in flat pyramidal structure, can ensure that transition expander roll inserts gradually smoothly and realize the mouth of pipe in closing waist type radiating tube and dilate; Because guide head and transition expander roll all have certain tapering, therefore expanding is very convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of closing waist type radiating tube before enlarging;
Fig. 3 is the structural representation of closing waist type radiating tube after enlarging;
Fig. 4 is the structural representation of radiator.
In figure: guide head 1, transition expander roll 2, expander roll 3, the body of rod 4, closing waist type radiating tube 5, pipe grid 6, radiating fin 7.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Figures 1 to 3: the termination of the body of rod 4 is fixed with expander roll 3, the front end of this expander roll is fixed with transition expander roll 2, the front end of this transition expander roll is fixed with guide head 1; The left and right sides of expander roll 3 are the flat-shaped structure of milling, upper and lower side is convex structure, and transition expander roll 2 is flat pyramidal structure, and guide head 1 is that front end is with meniscate flat scoop structure.
During enlarging, closing waist type radiating tube 5 and the utility model are fixed in fixture (not shown), by this fixture, guide head 1, transition expander roll 2 and expander roll 3 are pressed into gradually the mouth of pipe of closing waist type radiating tube 5, by described fixture, the utility model are exited from closing waist type radiating tube 5 after arriving desired depth.
As can be seen from Figure 4, the mouth of pipe of closing waist type radiating tube 5, after enlarging, effectively can be avoided closing waist type radiating tube 5 to be drawn out radiator core body drawing in swollen operation, thus can prevent pipe grid 6, radiating fin 7 from coming off from closing waist type radiating tube 5.
