Overview of straightener
With the development of national economy and industrial technology, the requirements of users on quality indexes of copper and copper alloy plate and strip are higher and higher. In recent years, although the hot and cold rolling equipment of copper strip is becoming more and more advanced, the flatness of strip type is improved to a great extent. However, from the perspective of production efficiency, equipment investment cost, equipment maintenance and other actual use effects, the equipment and rolling process alone will not meet the requirements of strip profile in electrical and electronic industries.
At present, 23 rolls stretching and bending straightening machine, which is specially designed for straightening copper strip profile, can effectively straighten the strip profile, and has been widely used and developed in the processing of copper strip profile. However, in the field of copper processing, due to many factors affecting the profile of copper strip, the profile is not easy to control. Among them, the most critical decisive factor is the precision and stability of the stretching and bending straightening machine itself. This paper mainly introduces how to ensure the high accuracy and stability of the stretching and bending straightening machine by optimizing the structure design and improving the machining precision of parts.
