Embodiment

[0014] A manufacturing method of a range hood net cover, the first step is to manufacture according to the shape of the net cover, making full use of computer-aided design technology, and making the graphics to be processed into positive and negative mask film through CAD / CAM; the second step is to make The film pattern is copied to the front and back sides of the metal material through photochemical reaction; the third step is to form a mesh pattern by exposing the front and back of the metal material, and the shape of the formed mesh includes the outermost mesh bottom 5 and the innermost mesh. The top 1 of the cover, the bottom 5 of the net cover and the top 1 of the net cover are connected by support ribs 4, and the structure of the net cover 6 is formed between adjacent support ribs 4; the fourth step is to corrode the mesh part by chemical corrosion method , so that a metal mesh panel with a mesh cover is formed between adjacent support ribs (such as figure 1 shown), the ...

Abstract

The invention relates to a range hood, in particular to a manufacturing method of a mesh cover of the range hood. According to the manufacturing method, mesh openings are formed by chemical corrosionfirstly, the roughness of the mesh openings of the mesh cover is guaranteed, the surface of the mesh cover is smooth without burrs, so that the deburring process is omitted, the thickness of link ribson the mesh cover is uniform after the mesh openings are corroded, and the influence of uneven stress on tensile fracture is reduced; and then the stretching process is utilized, and the mesh cover structure matched with the shape of a mold can conveniently form an arc-shaped convex surface, so that the oil guiding effect of the mesh cover is improved, and the use performance of the range hood isimproved.

Description

technical field [0001] The invention relates to a range hood, in particular to a method for manufacturing a net cover of the range hood. Background technique [0002] With the improvement of life now, more and more range hoods are used. The top suction range hood which is arranged on the top of the range hood and the side suction type which is placed on the side of the range hood. At present, most of the hoods on the market use a double-layer filter screen design, but the double-layer filter screen has disadvantages such as inconvenient cleaning, unsightly appearance, high cost, complicated production process, and poor air intake effect. Due to the many holes and thin ribs of the single-layer flat mesh cover, the traditional processing technology has many problems such as unsightly appearance, poor precision, difficult to handle burrs, easy to break when stretched, and low yield rate. For example, the Chinese patent: "The range hood and its filter screen and filter screen m...
