Drawing pipe according to an embodiment of the invention and the interior double-purpose processing unit (plant) that strips off the skin, further, the cylinder
Hollow pipe from the double-purpose core print is made up of identical or different metal, wherein preferably steel.
Drawing pipe according to an embodiment of the invention and the interior double-purpose processing unit (plant) that strips off the skin, further, the cylinder
Hollow pipe is provided with the outage that a circle is used for the sprinkling of trombone slide oil at it close to described screw rod one end.
Drawing pipe according to an embodiment of the invention and the interior double-purpose processing unit (plant) that strips off the skin, further, the trombone slide
The material of oily delivery hose is the plastic flexible pipe of rubber tube or oil resistant, excellent in the case where ensureing not by the corrosion of cooling oil
Select the material that matter is soft.
Invention effect
Drawing pipe provided by the present invention and the interior double-purpose processing unit (plant) that strips off the skin, tubing is realized with an easy equipment
Stretching and interior two purposes that strip off the skin, reduce equipment cost, and can effectively prevent the amount of heat during stretching or stripping off the skin
Generation cause tubing heating and at high temperature generation oxide layer the problem of, first pass through and stripped off the skin after drawing pipe, can be right
The size stripped off the skin is advantageously controlled, and is prevented that tubing is excessively stripped off the skin or stripped off the skin dynamics not enough, is improved the chi of tubing
Very little precision.

Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right with reference to embodiment and accompanying drawing
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
As illustrated in fig. 1 and 2, drawing pipe of the invention includes cooling tube 1, double-purpose core print with the interior double-purpose processing unit (plant) that strips off the skin
2, wherein the cooling tube 1 include cylinder hollow pipe 12, be connected to the cylinder hollow pipe 12 one end screw rod 13, be connected to
The oily delivery hose 11 of the trombone slide of the other end of the cylinder hollow pipe；The double-purpose core print 2 is a hollow circuit cylinder, the cylinder
One end expands outwardly horn-like in circular arc, and it is internally provided with screw thread.The cylinder hollow pipe 12 and the double-purpose core print 2 be by
What identical or different metal was made, wherein when the pipe 5 of processing is copper pipe, it is both preferably steel.Cylinder
Hollow pipe 12 is provided with the outage 14 that a circle is used for the sprinkling of trombone slide oil at it close to the one end of screw rod 13.The screw rod 13 it is straight
The internal diameter of footpath and the double-purpose core print 2 is configured to make cylinder hollow pipe 12 with double-purpose core print 2 by screw thread closely connect
It is connected together, such as the diameter of described screw rod 13 and the internal diameter of the double-purpose core print 2 can be identical.The trombone slide oil conveying is soft
The material of pipe 11 is the plastic flexible pipe of rubber tube or oil resistant, and in the case where ensureing not by the corrosion of cooling oil, preferably matter is soft
Material.
The drawing pipe is specifically described with the interior operating method for stripping off the skin double-purpose processing unit (plant) below.
Strip off the skin operation in being carried out first to copper pipe, as shown in figs. 1 and 3, is processed by present invention stretching with the interior double-purpose that strips off the skin
Device is used for interior strip off the skin in use, cooling tube 1 to be arranged on to the support 8 on workbench 6 by spring 7, by the arc of double-purpose core print 2
