More than.Hourglass pipe unit uses aluminium strip for raw material.By a series of linear deformation process, aluminium strip is made to be deformed into middle part with convex
The open-end tube of muscle produces hourglass pipe after high-frequency welding equipment welds.
However in existing hourglass pipe roll control system, two to match each other being arranged in top and bottom rolls roll wheel,
It is contacted carrying out the preform operation of rolling to aluminium strip with the contact condition of aluminium strip for line, it is inclined that this way of contact is easy to appear aluminium strip
Excessive phenomenon is moved and worn, causes hourglass pipe soldering unstable；On the other hand, single group rolls wheel in existing hourglass pipe rolling device
It synchronous to aluminium strip cannot carry out preform and belling muscle is handled, but individually be divided into two procedures completion, so increase equipment
Cost.
On the other hand the topping roll in existing hourglass pipe roll control system with bottom roll is controlled by same motor is synchronous
System, it is past so the speed of topping roll and bottom roll at work is unable to independent control, and when rolling the hourglass pipe of various specifications
Toward being because the speed that operates synchronously of top and bottom rolls is there are nuance, causing ratio-frequency welded tube to have, to will appear abrasion loss on one side bigger than normal
The phenomenon that.
Summary of the invention
