Volute ear folding device

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...
