Hydraulic Shaft Quick-Change System
The line adopts quick change system for the forming and sizing sections. The backup shafts can be pre-assembled with proper rollers. When switching, uses crown to load the shaft onto the production stands, settle the fixation bolt and connect to the transmission shaft (Transmission shaft is designed as quick-dissemble type which requires no is mount of flange plate screw). The dissemble of shaft utilize hydraulic system for easy operation. This kind of quick-change system has been tested in many scenarios which has proven to have perfectly deal with water back-flow issue and can simultaneously clear the scale cinder and dust while performing.
Quick Changing Shaft:
1) Application: It is used for rapid roller replacement. Install the roller of the next steel pipe to be produced to the quick-change shaft in advance. When the steel pipe specification needs to be changed, the quick-change mechanism of the rack will push out the shaft with roller specification in use, and the quick-change shaft installed with the new roller can be put into production, so as to achieve the effect of quickly changing the steel pipe specification.
2) Equipment composition: precision forming shafting unit, seam guide roll shafting unit, extrusion roll shafting unit, roll polishing roll shafting unit, pulling frame shafting unit, sizing straightening machine shafting unit.
Quick Changing System:
When produce round pipe: when changing rollers, pull out the side of the entire shafting unit, lift the shafting unit with the first roller specification from the transport trolley with the crown and put it aside, lift the shafting unit installed with the second roller specification, place it on the transport trolley, and then push the shafting back to the frame.

1. Roller change period with quick-change system: Appr. 8 hours (typically 1.5-2 days needed without quick-change system).
2. If equipped with additional set of shafts, the appr. roller change period is < 2hours
