Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0030] Specific examples are as follows, such as figure 1 As shown, the three-dimensional structural diagram of the air duct volute, the air duct volute is composed of two side plates 2 and an arc-shaped surrounding plate 1, and the side plates 2 and the surrounding plate 1 are processed in the form of extrusion wrapping.

[0031] like figure 1 and figure 2 As shown, the panel 1 includes a panel body 102 and a folded edge 101, and the side panel 2 includes a side panel body 202 and a folding ear 201. The folding ear 201 is at the same level as the side panel body 202 before being ...

Abstract

The invention relates to the technical field of air duct volute manufacturing, in particular to a volute ear folding device. The volute ear folding device comprises a coaming fixing mechanism for fixing coaming and a side plate fixing mechanism for fixing side plates. The volute ear folding device further comprises a bending mechanism. The bending mechanism comprises a transverse bending mechanismbody and a vertical bending mechanism body. Folded ears are transversely bent through the transverse bending mechanism body, and the transversely-bent folded ears are vertically bent through the vertical bending mechanism body. The automatic bending device is used for volute ear folding work, the problems that in the extruding and edge covering processes of a volute, in order to prevent the coaming and the upper and lower side plates from being scattered, the volute needs to be subjected to ear folding work firstly, and normal volute feeding and clamping of following process equipment are facilitated are solved, and the production efficiency and the product quality are effectively improved.

Description

technical field [0001] The invention relates to the technical field of air duct volute manufacturing, in particular to a volute ear folding device. Background technique [0002] In the prior art, many HVAC equipments are ventilated by the centrifugal fan, and the casing air duct volute of the centrifugal fan is usually produced by welding, and the air duct volute of the range hood in the prior art is usually made of Manual welding leads to high labor intensity, unsightly welds and low production efficiency. At the same time, as the country's environmental protection requirements become increasingly strict, the research and development of new processes and new equipment are vigorously advocated, and the energy consumption of welding processes and environmental pollution All will restrict the development of welding equipment. To solve this problem, the extrusion wrapping process has been developed to produce the air duct volute. During the extrusion and wrapping process of th...
