Manufacturing method for perforated metal plate shell of sound absorption wedge
A manufacturing method for a perforated metal plate shell of a sound absorption wedge comprises the steps of manufacturing a shell body, manufacturing shell side plates and splicing the perforated metal plate shell of the sound absorption wedge. The specific process comprises the steps that cut perforated metal plates are manufactured into the shell body with the periphery provided with L-shaped folded edges through a metal sheet technology; the cut perforated metal plates are manufactured into the shell side plates through an offset bending technology and the metal sheet technology, wherein Z-shaped folded edges are formed on the inclined edges of the shell side plates, and L-shaped folded edges are arranged at the tops of the shell side plates; then the shell body and the shell side plates are spliced through a clamping tool, and the L-shaped folded edges on the side faces of the shell body and the Z-shaped folded edges on the shell body side plates are connected in an overlapping mode; and then the L-shaped folded edges and the Z-shaped folded edges are connected and fixed in a butt-welding mode through a butt-welding machine, and the perforated metal plate shell of the sound absorption wedge is obtained. According to the manufacturing method, the manufacturing process is simplified, errors of structural connection are reduced, the product quality is improved while the structure strength of the perforated metal plate shell of the sound absorption wedge is ensured, and the attractive degree of the product is improved.
一种吸声尖劈穿孔金属板壳体的制造方法，包括了壳体主体的制作步骤、壳体侧板的制作步骤和吸声尖劈穿孔金属板壳体的拼装步骤，具体过程包括了通过钣金工艺将裁剪好的穿孔金属板制成四周具有L形折边的壳体主体、通过断差折弯工艺和钣金工艺将裁剪好的穿孔金属板制成其斜边上有Z形折边而顶部具有L形折边的壳体侧板，再通过夹持工装使壳体主体与壳体侧板进行拼合，使壳体主体侧面的L形折边与壳体侧板上的Z形折边进行搭接，再通过碰焊机将L形折边与Z形折边碰焊连接固定，制得吸声尖劈穿孔金属板壳体。本发明简化了制作工艺，减少了结构连接的错差，在确保吸声尖劈穿孔金属板壳体结构强度的同时，改善了产品品质，提高了产品的美观程度。
