The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1 and Figure 2.
The process equipment of tubing hole flanging comprises flanging die 1, parts such as holder baffle plate 2, drawing-die pressing plate 5 and pull bar 6.The bottom of flanging die 1 cooperates with the blind hole of holder baffle plate 2 end faces, and the bottom of flanging die 1 is inserted in the blind hole of holder baffle plate 2 end faces.The top of flanging die 1 is round table-like, and the bottom of the flanging die 1 gradually little and base diameter of diameter that makes progress is not more than the diameter of tubing 3 machining holes.Center line along flanging die 1 is provided with tapped through hole, and the center line of the threaded portion of pull bar 6 and flanging die 1 is provided with the tapped through hole immovable fitting.The below of holder baffle plate 2 is provided with the gag 4 of lifting effect, the structure of also available employing cam or employing spring lifting effect.Drawing-die pressing plate 5 bottom surfaces are provided with the concave surface that adapts with tubing 3 outer surfaces; as Fig. 3; drawing-die pressing plate 5 be provided with tubing 3 on the corresponding through hole in hole; the diameter of this through hole is greater than the flange diameter; its numerical value can add the maximum gauge of flanging die 1 bottom the wall thickness of tubing 3; the effect of this through hole is that flanging die 1 is pulled out in tubing 3 holes and forms flanging and at periphery protection flanging, this has clear and definite structural representation in Fig. 8.The effect of drawing-die pressing plate 5 is to prevent tubing 3 distortion.Drawing-die pressing plate 5 tops are provided with pull bar 6, and the bottom of pull bar 6 is provided with the external screw thread that cooperates with the tapped through hole of flanging die, and the top of pull bar is provided with mushroom-shaped structure and cooperates with the pulling claw axle 8 of stretcher.
Fig. 3, Fig. 4 are the SBR before stretching.Punching in advance on request on tubing 3, flanging die 1 quantity that is fixed on the holder baffle plate 2 is identical with the hole on the tubing 3 with center distance, will ask baffle plate 2 to be inserted in the tubing 3 together with flanging die 1, makes flanging die 1 consistent with the axle center, hole on the tubing 3.Fig. 5 is for being holder baffle plate lifting positioning states figure.The below of holder baffle plate 2 is provided with the gag 4 of lifting positioning action, and flanging die 1 top section is entered in the hole on the tubing 3.As Fig. 6 is tubing station moving structure schematic diagram.7 pairs of tubing 3 tops of fixing shelves mould bases that are connected with the basis are spacing, so that the pulling eye flange.After a flange was finished, the support roller that is positioned at tubing 3 bottoms drove tubing and moves to next position.
