Embodiment：
With reference to embodiment, the utility model is described in further detail, and purpose, which is only that, more fully understands the utility model
Content, therefore, the cited case are not intended to limit protection domain of the present utility model.
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 is by compressing
Screw 18 is provided 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 support 1,
The upper end of knife bar 7 is installed with crown chakra 5, and the lower end of knife bar 7 is provided with lower top wheel 11 by piston 10, and piston 10 is close by sliding
Seal 15 is arranged on knife bar 7, is formed between piston 10 and knife bar 7 inside seal cavity 14, knife bar 7 and is passed through laser process equipment
Duct 6 is machined with, the one end of duct 6 is connected with high-pressure water pipe 8, and the other end of duct 6 is connected with seal cavity 14, high-pressure water pipe 8
Bar magnet 3 is provided with by clamp 12 on outer ring and cooling water hole 13 for cooling down bar magnet 3 is machined with, bar magnet 3 is used to strengthen
Electromagnetic induction, increases induced-current, beneficial to welding, and due to bar magnet 3, temperature is very high, it is necessary to be water-cooled at work, passes through
Set cooling water hole 13 cooling water in high-pressure water pipe 8 is cooled down bar magnet 3, prevent bar magnet 3 because of the too high broken damage of temperature
It is bad, the body of burring knife 16 be in the inwall of welded still pipe 9 be adapted it is cylindric, the body of burring knife 16 and knife bar 7
The corresponding iron for going out to cut to be deburred in hole 17, welded still pipe 9 after knife 16 is removed is machined with head end respectively to cut from going out to cut hole
Discharged in 17, knife bar 7 is stainless steel one-step casting molding structure, it is to avoid high-frequency induction, increases cutter life.
Operation principle and using method, flat strip progressively bends to steel cylindrical tube in the presence of forming machine, sensing
Circle 2 in the induction of high frequency electric current of band steel edge 19, band steel edge 19 be heated by an electrical current after be in slush shape, then extruded in compression roller 4
Under be melted into one, the part metals of extrusion in the formation overlap 20 of the inwall of welded still pipe 9, it is necessary to remove, will with housing screw 18
Burring knife 16 is fixedly mounted on the head end of knife bar 7, by whole cutter through inside welded still pipe 9, by bar magnet 3 and compression roller 4
