 ABSTRACT

     This roll forming domestic and international outlook from the start, focusing on the roll forming technology, domestic and international development, the characteristics of rolling process, principles and processes. Then the shape of the refrigerator case, starting from the theory, the use of roll forming technology, design quality, manufacturing simple roller press. The design of the main to do the following: 1 roll forming in the design; two basic parameters of rolling process of the calculation; 3, the calculation of the number of roller wheels, roller spacing of the calculation and design, and direction in the horizontal and vertical adjustment; 4 on the main gear was checked.

This design is improved ,based on the former . Compared with the traditional molding process, it has significant advantages, shaping well and save material. Of course it still have some shortcomings and improved.
