Abstract
The utility model discloses a flanging-converging device for a circular tube. The flanging-converging device for a circular tube comprises a bottom plate and a top plate which are fixedly connected via a support rod, and a location device used for locating the circular tube is arranged at the centre of the bottom plate; and a through hole located on the same central axis with the location device is formed in the centre of the top plate, a copper sleeve which is in interference fit with the through hole is embedded in the through hole, a press head is connected in the copper sleeve in a penetrating manner, and the bottom end of the press head is in the shape of an arc corresponding to the shape needed by flanging for the circular tube. The flanging-converging device for a circular tube disclosed by the utility model is used for flanging and converging the circular-tube-shaped metal inwards, and has the advantages of being simple in structure, low in cost, and convenient to operate.
Description
Technical field
The utility model relates to tubing processing and manufacturing field, and is particularly a kind of for the device that flange closes up is carried out in the pipe end.
Background technology
Existing thin-wall metal pipe kind is more, butt welding is adopted in the welding that is applied between the thin-wall metal pipe on radiator and heat exchanger usually, its shortcoming is that tube wall is thinner, so that weeping to occur, can overcome the generation of this rosin joint phenomenon as adopting the flanging welded technology during welding Density inhomogeneity.But manual flange labour intensity is large, inefficiency, brings larger inconvenience to construction.As adopt dedicated hydraulic flanger or lathe roll extrusion to close up, exist equipment cost high, the shortcoming that clamping is loaded down with trivial details.When adopting in addition lathe roll extrusion mode to carry out the flange of the disconnected arm of pipe, also need the turner of specialty to operate, production efficiency is lower, and the degree of accuracy is lower.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of simple in structure, easy to operate pipe flange closing device.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Pipe flange closing device comprises the base plate and the top board that are fixedly connected with by support bar, and the center of described base plate is provided with the positioner for the location pipe; The center of top board is provided with the through hole that is positioned at same central axis with positioner, is embedded with the copper sheathing with the through hole interference fit in through hole, and in copper sheathing, cross-under has pressure head, and the bottom of described pressure head is and the corresponding arc of pipe flange required form.
Improvement of the present utility model is: be provided with on described top board and the corresponding hydraulic press in pressure head top.
Further improvement of the utility model is: described pressure head comprises depression bar and the pressure head cover that is threaded connection, and described depression bar is connected in copper sheathing, and pressure head overlaps the bottom and is provided with and the corresponding arc of pipe flange required form.
Owing to having adopted above technical scheme, the obtained technological progress of the utility model is:
The utility model is used for having advantages of flange and the closing in to the inside of circular tube shaped metal simple in structure, with low cost, easy to operate.Use the utility model that pipe is closed up, guaranteeing to have improved the degree of accuracy and production efficiency that flange closes up on the basis that pipe realizes that flange closes up.The structure that pressure head described in the utility model adopts depression bar and pressure head cover to be equipped with mutually can require to change the pressure head cover according to different flange and get final product, and has improved versatility of the present utility model.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1. top board, 2. copper sheathing, 3. pressure head, 4. support bar, 5. base plate.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
A kind of pipe flange closing device, its structure as shown in Figure 1.Comprise base plate 5 and top board 1, be fixedly connected with by support bar 4 between base plate 5 and top board 1.The shape of base plate 5 and top board 1 is circle in the present embodiment, and the quantity of support bar is 4.
The center of base plate 5 is provided with positioner, is used for pipe is vertically fixed on base plate, and makes a end that pipe need to turn over time be positioned at the base plate top.The center of top board is provided with through hole, and through hole and positioner are positioned on same central axis; Be embedded with and copper sheathing 2 copper sheathing and through hole interference fit in through hole; The interior cross-under of copper sheathing 2 has pressure head 3, and the bottom of pressure head is and the corresponding arc of pipe flange required form.Be provided with hydraulic press on top board 1, the pressing plate of hydraulic press is corresponding with the pressure head apical position.
When the utility model uses, will treat that at first the pipe that flange closes up is fixed in the positioner of base plate; Then the primer fluid press, utilize the pressure at right angle of hydraulic press that pressure head is pressed to pipe, and when the pressing plate of hydraulic press touched the top of pressure head, pressure head bore pressure, moves downward, and the circular arc by the pressure head bottom carries out flange to pipe and closes up; When pressure head touched pipe, the circular arc of pressure head bottom extruding pipe curved inwardly, and last flange becomes and the corresponding shape of pressure head circular shape.
Pressure head described in the utility model also can be set to split-type structural, namely is made of pressing plate and pressure head cover two parts, is threaded connection between depression bar and pressure head cover, and depression bar is connected in copper sheathing 2, and pressure head overlaps the bottom and is provided with and the corresponding arc of pipe flange required form; So that adapt to the demand that closes up without flange.
