Examples

The utility model discloses a concrete implementation mode is shown in fig. 1-4, a prevent mechanism of side turn-ups auto covering piece drunkenness, including setting up the location terrace die 15 and the lower mould side turn-ups shaping slider 11 that sets up and can reciprocate along location terrace die 15 edge at 1 upper surface of lower die base. The device also comprises a material pressing device 24 arranged on the lower surface of the upper die base 2 and matched with the positioning convex die 15 and an upper die side flanging molding insert 22 matched with the lower die side flanging molding slide block 11. Wherein, the upper surface of the lower die holder 1 is provided with a limiting rod 13 with one end contacting with the molded surface of the lower die side flanging molding slide block 11 in a floating manner. The lower surface of the upper die holder 2 is also provided with a front column 23 which corresponds to the limiting rod 13 and the lower end of which is lower than the molded surface of the upper die side flanging molding insert 22.

When the die is used for die assembly and flanging, the first-moving column 23 can press down the limiting rod 13, so that the pressing and flanging work between the lower die side flanging forming slide block 11 and the upper die side flanging forming insert 22 is not influenced, when the die is opened, the first-moving column 23 moves upwards, the limiting rod 13 moves upwards along with the limiting rod, and abuts against the automobile covering part which is flanged from the side, and then the lower die side flanging forming slide block 11 moves downwards to be separated from the automobile covering part. In the process that the lower die side flanging molding sliding block 11 moves downwards, the limiting blocking effect of the limiting rod 13 can prevent the automobile covering part from moving along with the downward movement of the lower die side flanging molding sliding block 11, and therefore the stability of the flanging molding quality of the automobile covering part is ensured.

Specifically, the movement of the driving plate 121 is driven by a pulley mechanism disposed on the lower die holder 1 and a slotting tool disposed on the upper die holder 2. When the press drives the upper die holder 2 to fall and perform die assembly, the driving plate 121 moves towards the side of the inclined guide plate 12, the inclined guide plate 12 and the driving plate 121 are changed from pairwise staggered arrangement into pairwise overlapped arrangement, so that the lower die side flanging forming slide block 11 can be pushed to move upwards by the thickness of one inclined guide plate 12, the molded surface of the lower die side flanging forming slide block 11 is consistent with the molded surface of the positioning male die 15, and the lower die side flanging forming slide block 11 can be driven.

Meanwhile, the lower die side flanging molding slide block 11 is also provided with an elastic reset element 19 for driving the lower die side flanging molding slide block 11 to reset. The elastic reset element 19 can drive the lower die side flanging molding slide block 11 to descend and reset after die opening, so that the lower die side flanging molding slide block is separated from contact with an automobile covering part.

In this embodiment, the other end of the limiting rod 13 extends towards the side away from the lower die side flanging molding slider 11. An elastic flanging ejector 14 for driving the limiting rod 13 to reset is arranged below one end, away from the lower die side flanging molding sliding block 11, of the limiting rod 13, and the first-moving column 23 is arranged above one end, away from the lower die side flanging molding sliding block 11, of the limiting rod 13. By arranging the elastic flanging ejector 14, when the limiting rod 13 is pressed by the pilot column 23, the descending and downward movement of the limiting rod can not be influenced, and further the die assembly flanging of the die can not be influenced. Meanwhile, after the die is opened, the elastic flanging ejector 14 can drive the limiting rod 13 to move upwards for resetting, so that limiting and blocking of the automobile covering part are completed, the automobile covering part can be prevented from moving along with downward movement of the lower die side flanging forming slide block 11, and further the stability of flanging forming quality of the automobile covering part is ensured.

The upper surface of the lower die side flanging molding slide block 11 is provided with a containing groove 111 for containing the limiting rod 13, so that a descending space can be provided for the limiting rod 13, and the influence of the limiting rod on the die assembly of the upper die base 2 and the lower die base 1 is avoided.

In addition, the lower surface of the upper die base 2 is provided with an upper die slide block 21 for installing an upper die side flanging forming insert 22, and a first-moving column 23 is arranged on the lower surface of the upper die slide block 21. And the lower die holder 1 is provided with a guide sliding surface 18 which is in sliding contact with the side wall of the upper die sliding block 21 which is far away from the side of the material pressing device 24. The slide guide surface 18 can ensure the accurate and smooth fit of the profiles of the upper die side flanging molding insert 22 and the lower die side flanging molding slide block 11, thereby ensuring the flanging precision of the automobile covering part.

In this embodiment, in order to assist in positioning the automobile panel, the positioning male die 15 is provided with a positioning pin 16. Similarly, a material stopper 17 is also arranged on the positioning male die 15. Both of these designs are conventional designs and are typically provided on a mold.

The specific working principle of the die using the mechanism is as follows:

before use, the automobile covering part to be punched is placed on the molded surface of the positioning convex die 15. Then, when the press drives the upper die holder 2 to fall and perform die assembly, the inclined guide plate 12 and the driving plate 121 supported below the lower die side flanging molding slider 11 are changed from pairwise staggered arrangement to pairwise overlapped arrangement, so that the lower die side flanging molding slider 11 is pushed to move upwards by the thickness of the inclined guide plate, and the profile of the lower die side flanging molding slider 11 is consistent with the profile of the positioning male die 15.

Next, the mold is closed continuously, and the swage 24 in the upper die base 2 first presses the automobile panel to be punched on the positioning punch 15. The upper die falls down to drive the upper die sliding block 21 to move and slide downwards along the sliding guide surface 18 side of the lower die base 1, the advance column 23 on the upper die sliding block 21 contacts the limiting rod 13 and compresses the elastic flanging ejector 14, the limiting rod 2 retreats into the accommodating groove 111 of the lower die side flanging molding sliding block 1, and the upper die side flanging molding insert 22 is driven to contact with the lower die side flanging molding sliding block 11 to complete part flanging molding.

When the press carries the upper die holder 2 to open the die, the upper die slide block 21 moves upwards along the side of the guide sliding surface 18 of the lower die holder 1 to slide, the leading column 23 is separated from the elastic flanging ejector 14, the limiting rod 13 moves upwards along with the elastic release of the elastic flanging ejector 14, rises from the accommodating groove 111 of the lower die side flanging forming slide block 1 and stops at the position for supporting the flanging outline of the part. Then, when the upper die holder 2 continues to open the die, the swaging device 24 is separated from the positioning convex die 15, and no swaging is performed. At this time, the two overlapped oblique guide plates 12 and the drive plate 121 below the lower die side flanging molding slider 11 are arranged in a staggered manner, and the lower die side flanging molding slider 11 moves downwards under the pushing of the elastic reset element 19, so that the lower die side flanging molding slider 11 retracts out of the flanging molding contour line of the automobile covering part.

In this case, since the stop rod 13 already holds the flanging surface of the automobile panel, the automobile panel on the profile of the positioning male die 4 has no tendency to move.

The present invention has been described above with reference to the preferred embodiments, but the present invention is not limited to the above-disclosed embodiments, and various modifications, equivalent combinations, which are made according to the essence of the present invention, should be covered.
