Description

A kind of deep bid heavy metal tubing wind

Technical field

The utility model relates to metal coil pipe processing technique field, particularly relates to the wind in a kind of metal pipe material (mainly being copper pipe) production.

Background technology

After twining unit and being positioned at the coil stretcher or copper pipe forming internal threads machine of copper, aluminium coil pipe workshop, major function be with dish draw with moulding after coil pipe in bulk be wound in whole dish in good order and coil, be indispensable equipment during coil pipe is produced.What twine coils the delivery to product of quality and neat degree direct influence.To reconnect the casting continuous rolling technology increasingly mature along with deep bid, at present both at home and abroad each big copper processing factory heavy copper pipe continuous casting continuous rolling production line of deep bid that starts one after another.The weight of single copper pipe has been increased to more than 1000 kilograms; the most of winding width of traditional wrapping machine are below 400mm; coil external diameter below 1100mm; coil weight below 300 kilograms; single copper pipe needs to be wound in three to four at least to be coiled, and needs frequent shutdown and unloads volume, and lumber recovery and productivity ratio are low; therefore, can not satisfy the requirement of the heavy copper pipe quantity-produced of deep bid.If the winding width of wrapping machine from the 400mm of traditional type be increased to 800mm, coil external diameter from

1100mm increases to During 1350mm, coil weight and will be increased to more than 500 kilograms, because loose core cylinder amount of deflection and complete machine rotary inertia increasing increase cause the wearing and tearing and the complete machine vibrations aggravation of sliding surface, simultaneously owing to rolling up the problems such as causing the tilting moment increasing that heavily strengthens.These problems are mainly reflected in following several respects, and 1, generally the wrapping machine collapsible drum all is fixed on the cylinder body front end of the cylinder of loosing core, cylinder body is finished in hollow shaft and under hydraulic oil drives by bearings and is loosed core and rise by the footpath action.Because the increase of winding width, the collapsible drum deadweight and the cylinder amount of deflection of loosing core increase, and cause cylinder body inconsistent at two place's shaft strengths, and cylinder surface is pulled easily when loosing core; Lubricated herein in addition difficulty, the relative steel bearing inner race of cylinder body are slided and are made cylinder surface wearing and tearing aggravation.2, wrapping machine is difficult to avoid loosing core the rotation of cylinder cylinder body when operate as normal, in case cylinder body rotates, the cylinder piston rod of loosing core sealing is easy to damage, and oil leakage phenomenon takes place, and contaminated environment can influence the wrapping machine operate as normal in the time of seriously.3, according to the wrapping machine design feature, machine gravity departs to outlet side, and during work, along with coil diameter and volume heavily strengthen, wrapping machine body tilting moment strengthens thereupon, and this safety to operating personnel can cause very big threat.

Summary of the invention
