Description

Technical Field

[0001] The invention belongs to the technical field of metal rolling, and in particular relates to a guiding device for rolling long metal products. Background Art

[0002] Rolling is a metal processing technology, which refers to a pressure processing method in which a metal billet is passed through the gap between a pair of rotating rollers, and the material cross-section is reduced and the length is increased due to the compression of the rollers. Rolling is the most commonly used production method for steel, mainly used to produce profiles, plates, and pipes. There are two types: hot rolling and cold rolling.

[0003] Traditional long metal rolling devices are prone to produce debris during rolling due to material reasons or other reasons. However, the positioning during the rolling process must be accurate so that the long metal's own gravity will not cause any deviation, otherwise defective products will appear during the rolling work. Therefore, most of the current rolling devices are rolled up and down, so that the long metal to be rolled can be directly extended along the rolling groove. However, the disadvantage of this is that it is necessary to frequently clean up the debris left in the groove during the rolling process. There is no good two-side rolling device that can ensure that the debris falls naturally and can hold the guiding standard without error. Summary of the invention

[0019] 2. When the rolling of the long metal cannot be completed in one time, the clamping and positioning assembly can be moved in the reverse direction until it is moved to the end closest to the part to be processed after rolling and fixed. The irregular shape after rolling can be fixed by setting multiple clamps, and then the above movement is repeated until it moves out of the rolling position of the rolling equipment with rolling rollers. Because the clamping and positioning assembly clamps the position after processing, two seamless rolling operations can be formed on the same long metal and there will be no problem of rotation of the workpiece to be processed.
