Refrigerator outer box puncturing and riveting production line

Abstract

The invention discloses a refrigerator outer box puncturing and riveting production line, which comprises a U-shell coaming production line, a back plate production line and a riveting production line. The U-shell coaming production line comprises the steps that (S11) feeding; (S12) carrying out punching; (S13) carrying out side bending; (S14) carrying out L-shaped bending; (S15) folding a U shape; the back plate production line process comprises the following steps: (S21) feeding; (S22) carrying out punching; (S23) carrying out side bending; (S24) clamping groove forming; (S25) carrying out overturning; the riveting production line process comprises the steps that (S31) a back plate turned over in the step (S25) is transferred to a riveting device; (S32) conveying the U-shaped coaming of step (S15) to the riveting device below the back plate; and (S33) enabling the riveting device to operate, and completing riveting work. According to the refrigerator outer box puncturing and riveting production line provided by the invention, the procedures of punching, bending, riveting and the like of the U-shaped coaming and the back plate are automatically completed, a traditional manual operation mode is replaced, the riveting working efficiency is improved, the personnel cost is reduced, and automatic production is promoted.

Description

technical field [0001] The invention relates to the technical field of freezer production, in particular to a puncture riveting production line for freezer outer boxes. Background technique [0002] At present, there are mainly two forming methods of riveting and welding for the preparation of the steel plate box of the refrigerator used in the refrigerator manufacturing industry. Among them, the riveting forming method mainly adopts the U-shaped coaming plate inserted into the riveting groove of the back plate. At present, the riveting production of the outer box of the refrigerator is usually done manually, the labor cost is high, the production efficiency is low, and there are U-shaped coamings. The inaccurate match with the backplane leads to a high reject rate. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide an automatic production line for piercing and riveting of the outer box of the refrige...
