Background technology
Spiral welded pipe forming machine is widely used in spiral welded pipe production, because stressing conditions are more complicated, and welds temperature
Degree is high, solder flux and dust are larger, format roll is easily damaged, not only causes stock consumption big, and maintenance cycle is short, seriously
It has impact on the normal production of spiral welded pipe.The basic reason of format roll damage is analyzed, one is due to that unreasonable structure causes pressure-bearing
Poor performance, it is exactly that lubricating condition is bad in addition.Existing format roll is more using common ball bearing as rotatable parts, its bearing capacity
It is relatively small.And the lubrication of format roll is lubricated using independent more, by loading lubricating grease or using lubricating cup oil injecting lubricating, continuous
In production process, format roll cannot timely and effectively lubricate.
The content of the invention
The invention provides a kind of Forming Roll for Spiral Weld Pipe and its lubricating system, lubricating method, it is made up of improved structure
And lubricating system, the service life of format roll is effectively increased, ensures being smoothed out for spiral welded pipe production.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of Forming Roll for Spiral Weld Pipe, including disk roller, roll shaft, bearing inner race, cylindrical roller and outer back-up ring；The roll shaft
On both sides of the middle is set with bearing inner race, and multiple cylindrical rollers are set on the outside of bearing inner race, disk roller, axle are set on the outside of cylindrical roller
Hold and set outer back-up ring between both ends, roll shaft and the disk roller of inner ring and cylindrical roller；Gap between 2 bearing inner races forms annular oil
Groove, annular oil groove connect with the horizontal oilhole on roll shaft, and roll shaft side sets longitudinal oilhole, and one end connection of longitudinal oilhole is laterally oily
Hole, other end set oil inlet；Sealing ring is set between outer back-up ring and disk roller.
A kind of lubricating system of Forming Roll for Spiral Weld Pipe, including roller seat, oil hose, oil dispenser and by fuel tank, oil pump,
The lubricating oil working connection of valve and oil pipe composition, longitudinal oilhole oil inlet of Forming Roll for Spiral Weld Pipe is corresponding with roller seat to be opened up
Oilhole sealing docking, the other end of roller seat upper oil hole are connected by joint with oil hose, the other end connection oil of oil hose
Distributor, oil dispenser connect lubricating oil working connection in addition.
Forming Roll for Spiral Weld Pipe lubricating method based on the lubricating system, Forming Roll for Spiral Weld Pipe are set in a row, each spiral shell
The oil inlet for revolving welded tube forming roll connects oil dispenser by the oilhole on corresponding roller seat and oil hose respectively；During lubrication, lead to
Oil pump is crossed by the lubricating oil in fuel tank after oil dispenser distributes, be transported in the oil inlet of each Forming Roll for Spiral Weld Pipe, then lead to
Cross longitudinal oilhole and horizontal oilhole is delivered lubricating oil in annular oil groove, so as to the rotation inside each Forming Roll for Spiral Weld Pipe
Part carries out sufficient lubrication.
Compared with prior art, the beneficial effects of the invention are as follows：
1) bearing inner race and cylindrical roller are coordinated into the revolute pair as Forming Roll for Spiral Weld Pipe, its contact surface is big, improves
The bearing capacity of format roll；
2) annular oil groove is set between bearing inner race, is delivered directly to lubricating oil by the oilhole opened up on roll shaft and roller seat
At rotatable parts, lubricity is good, is advantageous to improve the service life of format roll；
3) multiple Forming Roll for Spiral Weld Pipe are using forced feed lubrication form is concentrated, be advantageous to improve lubricating condition, reduce friction,
Reduce resistance of deformation.
