Quick-Change System
Specialized in Pipe Production Line
More than 23 years...
It is used for rapid roller replacement. Install the roller of the next steel pip e 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.
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.

Horizontal Stand Roller Quick-shaft Change System
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. It reduces roller replacement time for the entire mill from ~6 hours to ≤2 hours.
Quick Changing Shaft
When the pipe specification needs to be changed, preload the new specification 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. If equipped with additional set of shafts, the appr. roller change period is ＜2 hours.
