Specific implementation mode：
With reference to embodiment, the invention will be further described, and purpose, which is only that, more fully understands the content of present invention, because
This, the cited case is not intended to limit protection scope of the present invention.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, including knife bar 7, the head end of knife bar 7 passes through compression
Screw 18 is equipped with burring knife 16, and the tail end of knife bar 7 is welded with high-pressure water pipe 8, and high-pressure water pipe 8 is fixedly mounted on holder 1,
7 upper end of knife bar is installed with crown chakra 5, and 7 lower end of knife bar is equipped with lower top wheel 11 by piston 10, and piston 10 is close by sliding
Seal 15 is mounted on knife bar 7, is formed seal cavity 14 between piston 10 and knife bar 7, is passed through laser process equipment inside knife bar 7
It is machined with duct 6,6 one end of duct is connected to high-pressure water pipe 8, and 6 other end of duct is connected to seal cavity 14, high-pressure water pipe 8
Bar magnet 3 is equipped with by snap-gauge 12 on outer ring and is machined with the cooling water hole 13 for cooling down bar magnet 3, bar magnet 3 is for enhancing
Electromagnetic induction makes induced current increase, and is conducive to welding, since temperature is very high at work for bar magnet 3, needs to be water-cooled, pass through
Cooling water hole 13, which is arranged, makes the cooling water in high-pressure water pipe 8 cool down bar magnet 3, prevents bar magnet 3 because of the excessively high broken damage of temperature
It is bad, the ontology of burring knife 16 be in be adapted with 9 inner wall of welded still pipe it is cylindric, the ontology of burring knife 16 and knife bar 7
Be machined with respectively on head end it is corresponding go out to cut hole 17, the iron after knife 16 removes is deburred in welded still pipe 9 and is cut from going out to cut hole
It is discharged in 17, knife bar 7 is stainless steel one-step casting molding structure, avoids high-frequency induction, increases cutter life.
Operation principle and using method, flat strip gradually bend to steel cylindrical tube under the action of molding machine, induction
In 19 induction of high frequency electric current of band steel edge, band steel edge 19 squeezes after being heated by an electrical current in slush shape, then in compression roller 4 circle 2
Under be melted into one, the part metals of extrusion form overlap 20 in 9 inner wall of welded still pipe, need to remove, will with housing screw 18
