Method for processing dust-collection sheet of living air device

Abstract

The invention discloses a machining method for dust accumulation plate on living air device. The process flow is that at first, coil is cut into several strip bodies; pressure is applied to two sides of strip bodies gradually at the same time so that strip bodies are bended into tile shape, arc shape and cylinder shape with gap respectively and then a closed cylinder shape is welded at the gap on cylinder shape by solder; grinding is carried out at the welding gap position; and then canvas wheel coated by wax is set on the surface of circular tube and the surface of circular tube mentioned above is grinded and polished by canvas wheel group at different positions; grinded and polished circular tube is set between two extrusion mould and two sides are extruded so that two sides are extruded into ellipse and ellipse with transition arc; flat tube is formed and finally the formed flat tube is grinded and polished. Because dust accumulation plate adopts hollow tube strength of dust accumulation plate can be improved. Compared with prior machining method for dust accumulation plate, it is provided with convenient manufacture and low cost.

Description

【Technical field】 [0001] The invention relates to a processing method for manufacturing a dust sheet on an air purifier. 【Background technique】 [0002] In the prior art, the dust sheets used on air purifiers are mainly processed from steel plates, and the plate-shaped steel plates are cut into strip-shaped dust sheets. The thickness of the dust sheets is relatively thick, making processing difficult and costly. Because the dust sheet is cut, burrs and sharp corners are easily formed at the four corners of the dust sheet, and the burrs and sharp corners are likely to cause high-voltage discharges. In addition, when subjected to external pressure, it is easy to deform due to its low strength. 【Content of invention】 [0003] In order to solve the technical problem to be solved, the object of the present invention is to provide a method for processing dust sheets on air fresheners that is not only beneficial to improving strength, avoiding deformation and reducing costs, but...

[0002] In the prior art, the dust sheets used on air fresheners are mainly processed from steel plates, and the plate-shaped steel plates are cut into strip-shaped dust sheets. The thickness of the dust sheets is relatively thick, making processing difficult and costly

Because the dust sheet is cut, it is easy to form burrs and sharp corners at the four corners of the dust sheet. The burrs and sharp corners are likely to cause high-voltage discharges

In addition, when subjected to external pressure, it is easy to deform due to its low strength.
