Problems solved by technology

[0002] In the pipe forming equipment, there are many head forming equipment involved, and the processing methods are also various. The traditional processing method is cold heading forming. The forming mold must be processed first. The pipe diameter is different, and the mold is also different. The same pipe diameter The size of the drum is different, and the molds are also different, so that there are many molds in the production process, which is difficult to manage, and each time a different workpiece is processed, the mold must be replaced and then debugged, resulting in a waste of man-hours in the production process
Moreover, the mold has a certain life limit, and the entire mold needs to be reprocessed when it expires, resulting in various wastes.
The accuracy of cold heading forming is guaranteed by the mold. If there is a slight size adjustment, another mold can only be opened, which cannot meet the needs of flexible production.
