Description

A metal stamping die for side punching of a bridge structure

technical field

The utility model relates to the technical field of stamping dies, in particular to a metal stamping die with side punching of a bridge structure.

Background technique

Stamping dies are widely used in various mechanical processing fields. Stamping dies include dies that use punches to punch holes, so that the workpiece can be punched directly by punches, which is convenient for mass production and processing;

In the process of punching, the punched waste slides out through the waste chute. The traditional method is static and under the action of gravity, the direction of the blanking is poorly controllable, and the waste is easy to abut the inner wall of the waste chute, which is easy to block the side. Punching holes and not cleaning up the scrap chute in time will easily damage the punch and the lower die, which will seriously affect the production efficiency.

1-4, a metal stamping die for side punching of a bridge structure includes an upper die plate 2 and a lower die plate 1, an upper die pad 3 is installed on the upper die plate 2, and both sides of the lower end of the upper die pad 3 are installed respectively. There is a punch 17, a bracket 4 is installed in the middle of the upper die plate 3, and a pressing plate 6 is welded on the bracket 4. The pressing plate 6 is used to press the workpiece, so that the workpiece is stable during the punching process. A die base 9 is installed, a fixed base 8 is installed on the die base 9, a positioning base 7 is installed on both sides of the fixed base 8 through bolts, the positioning base 7 is covered with a hardware workpiece, and the middle of the positioning base 7 has a collecting Hole 11, a punch die 12 is installed on the positioning seat 7 near the punch 17, and a punching mechanism is installed on the positioning seat 7, through the punching mechanism, the waste material is repeatedly pushed to avoid the occurrence of automatic waste under the action of gravity. The blanking will cause the problem of uncontrollable stroke and blockage, so as to avoid the impact on the punch 17.

The punching mechanism includes a motor 10. The motor 10 is installed on both sides of the die base 9. The output end of the motor 10 penetrates into the positioning base 7 and is installed with a worm 18. The inner wall of the collecting hole 11 of the positioning base 7 is welded with a fixed block 16. , a rotating shaft is rotatably connected to the fixed block 16, and a turntable 15 is welded on the rotating shaft, a short pin shaft is welded on the outer ring of the turntable 15, and a pusher plate 13 is slidably connected in the collection hole 11, and the pusher plate 13 passes through The pin shaft is rotatably connected with the connecting rod 14, and the connecting rod 14 is rotatably connected with the short pin shaft on the turntable 15, the worm wheel 19 is welded on the rotating shaft, and the worm wheel 19 is engaged with the worm 18, and the turntable 15 is driven to rotate repeatedly by the motor 10, The turntable 15 drives the pusher plate 13 through the connecting rod 14 to push the waste material repeatedly.
