Description
Technical field
The utility model relates to a kind of impedor for high-frequency welding.
Background technology
In steel pipe HFI welding, the high frequency magnetic field of induction coil, at the appearance of the slotted pipe alternating current of inducting, applies power or electric energy to the edge of shaping pipe, when the temperature of tube edge is enough high and while being pressed together, smithwelding just occurs; For being focused on, welding current needs most the region of the energy, impedor is all housed in pipe, its effect is kelvin effect and the kindred effect of strengthening high frequency electric, so that being gathered in V-arrangement district, more electric current meets welding requirements, its installation site is in welding region, due to high temperature and foaming, need carry out cooling to impedor; Existing impedor comprises the sleeve pipe connected by resin and forward and backward nut, is provided with bar magnet in sleeve pipe, and sleeve pipe and bar magnet, in radial clearance setting, are equipped with cooling water hole on forward and backward nut; When use, front nut is connected with draw bar by screw thread, and back nut is threaded connection outlet pipe, drive impedor at in-pipe by draw bar, not only, installation bothers this structure, interchangeability is poor, and all external force acts directly on nut and sleeve pipe, nut is loosening and rotation easily, cause nut to separate with sleeve pipe, tensile strength is poor, and affects the Removing of inner burs device normal solution position that rear end connects, pin becomes flexible and scratches inner surface of tube, cannot normally work for a long time; It is cooling that the type of cooling is that cooling fluid enters immersion type in sleeve pipe, and poor effect, easily hardening cracks bar magnet.
Utility model content
The purpose of this utility model is for prior art above shortcomings, and a kind of high-frequency welding impedor is provided, and it has advantages of that installation is simple, interchangeability is good, tensile strength is high, can normally work for a long time, and good cooling results, applicability is strong.
For achieving the above object, high-frequency welding impedor of the present utility model, comprise sleeve pipe, be placed in the bar magnet in sleeve pipe, forward and backward nut, sleeve pipe and bar magnet are in radial clearance setting, characterized by further comprising connecting rod, one end of connecting rod is provided with the plane that is positioned at back nut, and this back nut is also provided with radially screw and several axially extending bore, and a holding screw is loaded on this radially in screw and compress the plane of connecting rod; Front nut is connected by screw thread with connecting rod, bar magnet is provided with endoporus, bar magnet and sleeve pipe are all placed on the connecting rod between forward and backward nut, in connecting rod, be provided with the inlet opening that is communicated with its front end and is arranged in bar magnet endoporus periphery, in front nut, be provided with several axially extending bores, the axially extending bore of forward and backward nut is all positioned at the inner side of sleeve pipe inner circle;
When use, connecting rod is connected with draw bar, and Removing of inner burs device is connected with back nut; The utility model is because forward and backward nut is all coupled on connecting rod, and sleeve pipe is clamped by forward and backward nut, and installation is simple, interchangeability is good; And external force is born by connecting rod, tensile strength is good, and nut, sleeve pipe do not stress, and nut is difficult for loosening, and holding screw can prevent that back nut and sleeve from rotating, and can normally work for a long time; Inlet opening to connecting rod and the axially extending bore of front nut pass into cooling water, and are discharged by the axially extending bore of back nut, can carry out the inside and outside periphery of bar magnet coolingly, and realize and force coolingly, and better effects if, extends life-span of bar magnet;
As further improvement of the utility model, several axially extending bores of described front nut are positioned at the first half of its circumferential section, and several axially extending bores of back nut are uniform on its circumferential section; Both can ensure that inside existed cooling fluid all the time, discharge opeing is smooth and easy again;
As further improvement of the utility model, described front nut is non-metallic material, and as polytetrafluoroethylene (PTFE), back nut is copper, is also provided with copper clamp nut on the connecting rod of front nut front end, and the external diameter of clamp nut is less than front nut; Bar magnet is ferrite; Front nut is non-metallic material, and because this end is near coil, the external diameter of clamp nut is less than again front nut, both can reduce kelvin effect on high frequency electric and the impact of kindred effect, ensures again bonding strength;
In sum, the utlity model has the advantage simple, interchangeability is good, tensile strength is high is installed, can normally work for a long time, and good cooling results, applicability is strong.
