It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Example

As shown in Figures 1-3, the flanging die assembly for a ductile sheet material that is convenient for blanking described in this embodiment includes a fixed die plate 1, and a movable die plate 2 is arranged above the fixed die plate 1. The movable die plate 2 The top of the plate is connected with a driver, and the driver drives the movable template 2 to move up and down. The driver can use a hydraulic cylinder, a pneumatic rod or a linear motor. The fixed template 1 includes a die block 11, and the top of the die block 11 is provided with A mold groove 12, the mold groove 12 is matched with the movable template 2, and auxiliary flanging devices 3 are provided on both sides of the mold groove 12;

The auxiliary flanging device 3 includes an arc-shaped groove 31 . Both sides of the mold groove 12 are provided with arc-shaped grooves 31 . 12 is connected, a turning plate 32 is arranged above the arc-shaped groove 31, the bottom surface of the turning plate 32 is arc-shaped, and the bottom surface of the turning plate 32 extends into the arc-shaped groove 31 to cooperate with the arc-shaped groove 31, and is turned over One side of the plate 32 protrudes into the die groove 12, the turning plate 32 is fixedly connected with a rotating shaft 33, the rotating shaft 33 is movably connected to the die block 11 through a bearing, and the rotating shaft 33 is located at the center line of the circle where the bottom surface of the turning plate 32 is located. superior.

The flanging die assembly of the ductile sheet that is convenient for blanking proposed by this technical solution is provided with an auxiliary flanging device 3 on the fixed template 2, so that the sheet can be easily taken out after the stamping operation is completed.

The overturning plate 32 is used to accept the flanging of the sheet, and during the overturning process the overturning plate 32 rotates with the non-overturning part of the sheet, which can avoid the deformation of the bending part of the sheet without turning over, which helps to improve the yield.

When working, the plate is placed on the top of the fixed platen 1, and the moving platen 2 falls to press and bend the plate into the die groove 12. When the plate is bent, the turning plate 32 rotates with the non-reversing part of the plate. When the plate is taken out, it is only necessary to put the plate Lift up, and the flip plate 32 returns.

A plurality of thin grooves 34 are formed on the groove bottom of the arc-shaped groove 31 , the thin grooves 34 are parallel to the arc-shaped groove 31 , and the groove bottom of the thin groove 34 is arc-shaped. A round rod 35 matched with the thin groove 34, the round rod 35 is coaxially arranged with the arc-shaped groove bottom of the thin groove 34, and one side of the round rod 35 extends into the arc-shaped groove 31 and contacts the bottom surface of the turning plate 32 .
