Abstract
The utility model discloses the swollen head of a kind of production automobile radiators enlarging.Comprise body part (1), body part (1) is connected with the flared part (2) of elliptic cylindrical shape, and flared part (2) is connected with leader (3).The front end of leader of the present utility model is much narrower than radiating tube, the sidewall on leader or leader and inclined-plane is utilized to carry out enlarging to radiating tube, facilitate when radiating tube draws swollen expander roll can insert radiating tube fast, save time and efforts, substantially increase production efficiency; The utility model utilizes the simple connection of body part, flared part and leader can realize the function of enlarging, and structure is simple, easy to operate.
Description
Technical field
The utility model relates to the swollen head of a kind of enlarging, particularly the swollen head of a kind of production automobile radiators enlarging.
Background technology
Radiating tube in automobile radiators in process of production, need to utilize expander roll to insert in radiating tube to dilate radiating tube, and the radiating tube of finished product, some mouths of pipe are more flat, and not quite, direct line up carries out the words of processing for some mouth of pipe bores and expander roll different widths, expander roll can be made to be difficult to through radiating tube, cause the phenomenon that processing is more difficult, and waste time and energy again, greatly reduce production efficiency.
Summary of the invention
The purpose of this utility model is, provides a kind of and produces the swollen head of automobile radiators enlarging.Conveniently can process radiating tube after its enlarging completes, save time and efforts, improve production efficiency, and relatively simple for structure, operate more convenient.
The technical solution of the utility model: the swollen head of a kind of production automobile radiators enlarging, comprise body part, body part is connected with the flared part of elliptic cylindrical shape, and flared part is connected with leader.
In the enlarging of aforesaid production automobile radiators is swollen head, described leader is that blade is trapezoidal.
In the enlarging of aforesaid production automobile radiators is swollen head, the sidewall of described flared part is provided with enlarging inclined-plane.
In the enlarging of aforesaid production automobile radiators is swollen head, the tapering of described leader is: 20-50 degree, and the inclination angle on enlarging inclined-plane is: 30-50 degree.
In the enlarging of aforesaid production automobile radiators is swollen head, the tapering of described leader is: 35 degree, and the inclination angle on enlarging inclined-plane is: 40 degree.
Compared with prior art, the front end of leader of the present utility model is much narrower than radiating tube, the sidewall on leader or leader and inclined-plane is utilized to carry out enlarging to radiating tube, facilitate expander roll can insert radiating tube fast when radiating tube draws swollen, save time and efforts, substantially increase production efficiency; The utility model utilizes the simple connection of body part, flared part and leader can realize the function of enlarging, and structure is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is side view of the present utility model.
Being labeled as in accompanying drawing: 1-body part, 2-flared part, 3-leader, 4-sidewall, 5-enlarging inclined-plane.
Detailed description of the invention
Embodiment.The swollen head of a kind of production automobile radiators enlarging, form as depicted in figs. 1 and 2, comprise body part 1, body part 1 is connected with the flared part 2 of elliptic cylindrical shape, and flared part 2 is connected with leader 3.The width of described flared part 2 is more smaller than radiating tube bore, and the width of body part 1 is more than or equal to the bore of radiating tube.
Described leader 3 is that blade is trapezoidal.The width of the front end of described leader 3 is narrower than the width of flared part 2, and rear end is connected with flared part 2.
The sidewall 4 of described flared part 2 is provided with enlarging inclined-plane 5.Described sidewall 4 can be arranged to each one or the right and left around to be had.
The tapering of described leader 3 is: 20-50 degree, and the inclination angle on enlarging inclined-plane 5 is: 30-50 degree.
The tapering of described leader 3 is: 35 degree, and the inclination angle on enlarging inclined-plane 5 is: 40 degree.
The utility model is the function by utilizing the simple connection of body part 1, flared part 2 and leader 3 can realize enlarging.First the front end of leader 3 is much narrower than radiating tube, radiating tube can be inserted quickly and easily, width due to body part 1 is more than or equal to the bore of radiating tube, after making flared part 2 insert radiating tube, body part 1 is blocked by the radiating tube mouth of pipe to be stayed outside radiating tube, by utilizing flared part 2 to carry out enlarging to the heat radiation mouth of pipe, or utilize the effect on sidewall 4 on flared part 2 and enlarging inclined-plane 5, enlarging is carried out to the flat place of the heat radiation mouth of pipe.
