The specific implementation principle of the device for punching, half-cutting and forming the automobile airbag gas filter screen of the embodiment is as follows:

firstly, the whole upper die base moves downwards towards the lower die base, when the upper stripper plate 18 contacts the material lifting rod 41, the upper stripper plate 18 presses the material lifting rod 41, so that the material lifting rod 41 gradually presses the fifth spring until the material strip 1 is attached to the lower fixing plate 22, in the process, the lower stripper block 35 is gradually accommodated in the forming cavity 30 under the action of the upper stripper plate 18, but the forming male die 12 and the forming upper top block 8 do not perform forming processing on the material strip 1 at the moment. After the material strip 1 is attached to the lower fixing plate 22, the aligning nail 5 penetrates the material strip 1 and then extends into the aligning cavity 9, i.e. the aligning hole 3 is formed in the material strip 1.

After the pilot hole 3 is formed on the material belt 1, the upper die base continues to press downwards, so that the second spring 26 is pressed by the sleeve, the longitudinal distance K between the upper discharging base plate 17 and the upper discharging plate 18 is gradually reduced along with the compression of the second spring 26, at this time, the guide hole male die 38, the punching male die 6, the half-cutting male die 7, the upper forming ejector and the forming female die 23 gradually extend out of the upper discharging plate 18, and the half-cutting male die 7 presses the half-cutting ejector block 32 along with the continuous pressing downwards of the upper die base, so that the half-cutting male die 7 and the half-cutting ejector block 32 form half-cutting processing on the product blank 2; the punching male die 6 is matched with the punching female die 10 to form punching processing on the product blank 2; and the acting force which is applied to the upper forming ejector by the forming convex die 12 and is opposite to the moving direction of the upper die base enables the upper forming ejector to press the first spring 25, so that the forming concave die 23 is pressed against the lower discharging block 35, namely, a forming processing interval of the product blank 2 is formed under the action of the forming concave die 23 and the lower discharging block 35, and the forming convex die 12 and the upper forming ejector perform forming processing on the product blank 2. At the same time, the upper cutter 46 and the lower cutter 47 cooperate to cut the waste area on the material tape 1, so that the punching, half-cutting and forming and waste cutting operations on the material tape 1 are completed. After the processing is completed, the upper die base moves upwards relative to the lower die base, the material lifting rod 41 resets and drives the material belt 1 to move upwards relative to the lower fixing plate 22 in the resetting process, so that the material belt 1 is convenient to convey continuously, and a product formed after the forming processing is carried on the lower discharging block 35 and forms a separation effect with the material belt 1. For products which have here been separated from the material web 1 and which are carried on the lower stripper block 35, the collection of the products can be carried out by means of, for example, but not limited to, a robot for gripping escape.

After the primary punching, half-cutting, forming and waste cutting are finished, the material belt 1 is conveyed and moved mechanically, the steps are continuously repeated, the pilot hole 3 is formed, and then the punching, half-cutting, forming and waste cutting are carried out.

The blowing that the material subassembly was carried on the product on unloading piece 35 is blown to this embodiment makes the product be convenient for enter into product collecting groove 50 along with the blowing direction, mainly aims at that the product part of this embodiment is little and the light characteristics of material.

In detail, the product catch basin 50 is disposed obliquely with respect to the lower mold base 19 so that the product blown down within the product catch basin 50 can slide along the product catch basin 50 to be finally carried into the product collection bin.

For example, the blowing assembly adopted in the present embodiment includes a blowing copper tube 51 adapted to face the product loaded on the lower discharging block 35, a blowing fixing base 53 for fixing the blowing copper tube 51, a gas tube connector 55 disposed on the blowing fixing base 53 and connected to the blowing copper tube 51, and a gas inlet tube 57 connected to the gas tube connector 55. The blowing copper pipe 51 blows air towards the products loaded on the lower discharging block 35, that is, the blowing assemblies are arranged opposite to the product collecting grooves 50, and are respectively perpendicular to two sides of the conveying direction F of the material belt 1.

The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship which is usually placed when the product of the present invention is used, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

Furthermore, the terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the present disclosure, unless otherwise expressly stated or limited, the first feature may comprise both the first and second features directly contacting each other, and also may comprise the first and second features not being directly contacting each other but being in contact with each other by means of further features between them. Also, the first feature being above, on or above the second feature includes the first feature being directly above and obliquely above the second feature, or merely means that the first feature is at a higher level than the second feature. A first feature that underlies, and underlies a second feature includes a first feature that is directly under and obliquely under a second feature, or simply means that the first feature is at a lesser level than the second feature.
