Abstract：

As for the ice-making equipment for thin-walled copper tube bending, the annealing, lubrication and bending technology were designed after analyzing the stress and strain conditions in the bending process and quality problem reasons. According to the material deformation characteristics, the bending mould was designed and using the anti-deformation slot and pipe deformation mandrel, the wrinkle in the bending process and outer edge flat defects were solved. The production practice proves that it is a reasonable process, the mold structure is simple and practical, processed products are of good quality and suitable for small batch production.
