Problems solved by technology

At present, most of the fan boxes are composed of multiple parts welded, the connection effect between the parts is poor, the process is many, and the productivity is low. Since each part is stamped by cold-rolled plate, the thickness is small, and the spot welding process is required. Higher, resulting in The pass rate of this type of fan box is low, resulting in high product cost. Designing a fan box that uses cold-rolled plate stamping and does not require spot welding will greatly improve the production efficiency and pass rate of this type of fan box, and reduce the production cost of the product. , beneficial to consumers

Embodiment Construction

[0028] see Figure 1 to Figure 4 According to the embodiment of the fan box provided by the present invention, it includes a body, the body is respectively provided with an air inlet 3, an air outlet 4, and a cooling hole 5, and the body is also provided with reinforcing ribs and a fan installation position, and the body Integral stamping and forming. The body includes a bottom plate 1 and a plurality of side plates 2 arranged around the bottom plate. The bottom plate 1 and the side plates 2 are integrally structured, and the side plates 2 are folded upwards to be perpendicular to the bottom plate 1 . The adjacent side plates 2 are riveted and fixed. The present invention is simple in structure, convenient and quick to manufacture, adopts integral stamping and riveting forming, each side plate 2 and the bottom plate 1 are integrally structured, and the side plates are fixed by riveting, compared with traditional welding, the connection is more reliable and the sealing effect ...

Abstract

The invention discloses a fan box which comprises a body. An air inlet, an air outlet and a heat dissipation hole are respectively arranged on the body; a reinforcing rib and a fan mounting position are also arranged on the body; and the body adopts integral punch forming. The fan box has the benefits that the structure is simple, the fan box is convenient and rapid to manufacture and adopts integral punch riveting forming, all side plates and a bottom plate form an integral structure, all the side plates are fixed through riveting, compared with the traditional welding, the connection is firmer, the sealing effect is better, and simultaneously, the production efficiency and the yield of products are greatly improved.

Description

technical field [0001] The invention relates to a fan box, and also relates to a mold for processing the fan box and a processing technology of the fan box. Background technique [0002] At present, there are many kinds of heating appliances, among which the heating appliances that use the principle of the heater are the most, such as air-conditioning fans, heating and cooling fans, fireplaces, etc. Inside, the fan box is provided with an air inlet and an air outlet. At present, most of the fan boxes are composed of multiple parts welded, the connection effect between the parts is poor, the process is many, and the productivity is low. Since each part is stamped by cold-rolled plate, the thickness is small, and the spot welding process is required. Higher, resulting in The pass rate of this type of fan box is low, resulting in high product cost. Designing a fan box that uses cold-rolled plate stamping and does not require spot welding will greatly improve the production eff...
