As an embodiment of the present invention, one end of an auxiliary pipe 9 is connected to the gas outlet end of the main pipe 8; through two adjacent main pipes 8 and the same auxiliary pipe 9 intercommunication for the gaseous impact force of passageway combustion gas is bigger, and the effect that gaseous to blank surface piece was clear away is strengthened.

As an embodiment of the present invention, a gas check valve 11 is provided in the gas inlet end of each airbag 6; a one-way valve 11 is also arranged inside one end of each secondary pipe 9; through check valve 11 for when gasbag 6 was propped the volume increase and is inhaled the air by spring 7, gas is restricted and can only be derived from the outside air, can't inhale gasbag 6 through the passageway in the die, avoids gasbag 6 to inhale and has clastic gas, and when gas was bloated from gasbag 6 in, gas only can flow out to the passageway from accessory tube 9 in, thereby the more effectual piece that is used in the blank of gas.

As an embodiment of the present invention, both ends of each first spring 7 are provided with rubber plates 12, and both ends of the first spring 7 are connected to the inner surface of the airbag 6 through the rubber plates 12; through rubber slab 12, when guaranteeing that spring 7 props up gasbag 6 fast, when avoiding pushing away futilely to push down gasbag 6 and spring 7, spring 7 extrudees gasbag 6 many times, and spring 7 extrudees the emergence of the phenomenon of rupture with gasbag 6, and through rubber slab 12 for gasbag 6 is protected with spring 7 contact point.

As an embodiment of the present invention, each of the push rods 4 includes a first rod 13, a second rod 14 and a second spring 15; one end of the first rod 13 is fixedly connected with the lower plate surface of the fixing plate 3, the other end of the first rod 13 is provided with a sliding hole 16, the inner top surface of the sliding hole 16 is fixedly connected with one end of a second spring 15, the other end of the second spring 15 is fixedly connected with one end of a second rod 14, one end of the second rod 14 is slidably connected into the sliding hole 16, and the other end of the second rod 14 is slidably connected into the groove 10; fixed plate 3 pushes down 4 push rods of push rod 4 and extrudees gasbag 6 and spring 7, when avoiding spring 7 to be compressed to the limit, push rod 4 still extrudees spring 7, causes the emergence of a spring 7 damage phenomenon, cushions the displacement of a pole 13 through No. two spring 15, when spring 7 was compressed will extremely, No. two spring 15 was compressed and is cushioned the displacement of a pole 13 promptly, avoids a spring 7 to be extruded and damages.

As an implementation mode of the utility model, a rectangular hole is arranged on one side wall of each base block 5, a filter plate 17 is arranged at the outer hole end of the rectangular hole, and the inner side of the filter plate 17 is the air inlet end of the air bag 6; the gas sucked into the air bag 6 from the outside is filtered by the filter plate 17, so that the gas with particles is prevented from being discharged onto the blank.

As an implementation mode of the present invention, a rectangular groove 18 is formed on one side wall of each base block 5, a filter plate 17 is embedded in the rectangular groove 18, an elastic plate 19 is arranged at an upper notch of the rectangular groove 18, one side edge of the elastic plate 19 is fixedly connected to the rectangular groove 18, and the other side edge of the elastic plate 19 is attached and pressed on the filter plate 17; the filter 17 is placed in rectangular channel 18, and filter 17 is extruded by elastic plate 19 in rectangular channel 18 simultaneously, when guaranteeing that filter 17 is filterable to the air, realizes filter 17's convenient clearance of removing.

The working principle is as follows: when a blank is placed in a female die of a lower die 2, the blank collides with the female die, so that scraps on the blank are scattered by vibration, when an upper die 1 gradually approaches the lower die 2, the upper die 1 drives a fixing plate 3 to move, meanwhile, the fixing plate 3 presses a push rod 4 downwards, the push rod 4 gradually extends into a groove 10 of a base block 5, then the other end of the push rod 4 extrudes an air bag 6, air in the air bag 6 sequentially flows through a main pipe 8 and an auxiliary pipe 9, finally, the air is blown into a channel of the female die, is discharged from the channel and impacts the surface of the blank, the scraps on the surface of the blank are knocked off and fall into a gap between the blank and the female die, and the scraps at the moment cannot influence the punch forming of the blank; the power of the gas blowing comes from the thrust generated when the upper die 1 moves close to the lower die 2, the power resource is fully utilized, and the scraps on the surface of the blank are removed before the blank is subjected to punch forming, so that the product quality of the blank subjected to punch forming is better;

the two adjacent main pipes 8 are communicated with the same auxiliary pipe 9, so that the impact force of gas discharged from the channel is larger, and the effect of the gas on removing scraps on the surface of the blank is enhanced;

meanwhile, through the check valve 11, when the air bag 6 is supported by the first spring 7 to increase the volume and suck air, air is limited to be only from outside air, and cannot be sucked into the air bag 6 through the channel in the female die, so that the air bag 6 is prevented from sucking air with fragments, and when the air is blown out from the air bag 6, the air can only flow out of the channel from the auxiliary pipe 9, and therefore the air can more effectively act on the fragments on the blank.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
