detailed description

Now in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

As shown in Figure 1, a kind of automatic production line of automobile audio stamping parts comprises automatic feeder, precision progressive die, automatic tapping machine and conveyer; Described precision progressive die comprises an upper die assembly, lower die group Components and a fault display, the upper surface of the lower mold assembly is provided with a material belt, and the two sides of the material belt are provided with a grooved floating top pin 8 and a grooved guide block 9 along the moving direction of the material belt; the automatic tapping machine includes multiple A motor 13 for tapping and a plurality of positioning devices 14 for fixing workpieces, the front end of the motor 13 is connected with a tapping head 15 .

In this embodiment, the upper mold assembly includes an upper template 1, the upper template 1 is provided with a punch fixing plate 6 and an upper stop plate 7, and a discharge plate 10 is provided below the punch fixing plate 6. , several punches 5 with different diameters are installed in the punch fixing plate 6 , wherein a pressure sensor 12 is provided between the punches 5 with a diameter less than 2mm and the upper template 1 .

The lower mold assembly includes a lower template 2, on which several dies 3 and die inserts 4 are arranged, and on the lower template 2, an elastic material block 11 is also arranged.

The automatic feeder adopts an uncoiler, and the uncoiled plate is transported to the material belt of the precision progressive mold.

The motor 13 is connected with a power device 16 for the axial movement of the tapping bit, and the power device 16 adopts a hydraulic cylinder.

The positioning device is composed of a cylinder 14.1, a connecting rod 14.3, a briquetting block 14.5 and a stopper 14.4. The briquetting block 14.5 is fixed on the upper end of the connecting rod 14.3, and the middle and lower part of the connecting rod 14.3 is connected to the guide rod of the cylinder 14.1. 14.2 is hinged, and the stopper 14.4 is set at the position corresponding to the lower end of the connecting rod 14.3 in front of the cylinder 14.1.
