Problems solved by technology
At present, the automotive air filter is composed of a shell, a filter element, an end cover, a filter screen (including an inner filter screen and an outer filter screen), and the filter screen is an ordinary reel-shaped mesh structure, and the material is metal. Multiple pieces of filter screens are welded together, leaving welding points. According to different specifications, they are cut and discarded, which is wasteful and has poor strength.

Embodiment Construction
[0010] The present invention will be described in further detail below with reference to the drawings and embodiments.
[0011] refer to figure 1 , figure 2 As can be seen, the manufacturing method of the spiral filter screen gained by the present invention: at first, the sheet metal 20 (quadrilateral) is notched by the notch device 1 (having a notch mold 23) (the two sides of the sheet metal are not processed), and then, The stretching device 10 stretches the sheet metal with several notches, and the leveling device 4 (in the form of rolling up and down, is two pieces, has a strengthening and stabilizing effect) performs a leveling process, so that the The metal plate forms the filter screen semi-finished product of mesh structure (for unfolding type); Then, the both sides of the filter screen semi-finished product of this mesh structure are by flanging device 11 (has flanging sprocket wheel 22, is two pieces, one in The top and the other piece are under the flanging proce...

The invention discloses a filter screen stretch-flanging forming mechanism. A cutting device (1) is installed on a machine frame (13) and is connected with a drive device (6) through a first transmission device (2), the other end of the first transmission device is connected with a leveling device (4), and a stretching device (10) is installed between the cutting device and the leveling device. A flanging device (11) is arranged on the machine frame (13) and located at the side position of the leveling device and is connected with the drive device (6). A filter screen provided with a turnup and a meshy structure, produced by the filter screen stretch-flanging forming mechanism, is subjected to splicing and edge sealing to form a spiral filter screen, welding treatment is needed no longer, no side crops exist, and a splicing and edge sealing strip in the middle further has the effect of improving the strength of the filer screen. The filter screen stretch-flanging forming mechanism is quick and convenient to manufacture, simple in structure, high in university and reliability and low in cost.
Description
technical field [0001] The invention relates to a filter screen for an air filter, in particular to a forming mechanism for the filter screen of an air filter. Background technique [0002] The air filter is a filter device installed in the intake system of the internal combustion engine of the vehicle. It is used to provide clean air for the combustion in the engine cylinder, so as to prevent the internal combustion engine cylinder block and its parts from being abraded and damaged by the inhaled impurities and dust during work. . At present, the automobile air filter is composed of a shell, a filter element, an end cover, a filter screen (including an inner filter screen, an outer filter screen) and other components. Multiple pieces of filter screens are welded together, leaving welding points, cutting according to different specifications and discarding side materials, which is wasteful and has poor strength. Contents of the invention [0003] The purpose of the prese...
