Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
The powerful impedor of a kind of asymmetric magnetic core, comprises impedor body 11, magnetic core 3, tetrafluoro pillar 2 and positioning sleeve 8; Impedor body is for installing magnetic core, connecting positioner and scraping scar bar, and magnetic core is used for making steel pipe produce impedance, and make induced-current gather weld bond place, tetrafluoro pillar and positioning sleeve are for the protection of fixed magnetic core, water conservancy diversion cooling water; Tetrafluoro protective pipe sleeve is contained on impedor body, and magnetic core ring is loaded on asymmetric round tube body on tetrafluoro pillar internal impedance device body, and positioning sleeve is installed in location division on impedor body.Impedor body, by draw rod attachment part 1, asymmetric round tube body 4, location division 7, scrapes scar bar connecting portion 9 and forms, and draw rod attachment part, asymmetric round tube body, location division, scrapes scar bar connecting portion and connects successively and be made as one; Draw rod attachment part is used for being connected with locator, asymmetric round tube body for installing the magnetic core be made up of reducing bar magnet, location division for install stationary positioned cover to make reducing bar magnet, tetrafluoro pillar is fixed, scrape scar bar connecting portion and scrape scar bar for installing connection; Impedor body central is axially shaped with impedor mesopore 5.Asymmetric round tube body, its cross section was upper profound moon shape, and asymmetric round tube body radial direction is shaped with water hole.Magnetic core is asymmetric magnetic core, and asymmetric magnetic core is one to four joint, and the utility model is two joints, to be often contained in around asymmetric round tube body near the chain of rings mutually before and after joint and to be wrapped up by tetrafluoro pillar, often saving and form by reducing bar magnet 10; Reducing bar magnet is ten to two ten five, and its cross section is that five lobes are quincunx or six lobes are quincunx, and its outside diameter is four to ten eight millimeters of plurality of specifications.The present embodiment is 22 quincunx bar magnets of five lobes, and its arrangement mode is: top
middle part
bottom
bar magnet cross section is that quincunx or quincunx being convenient to of six lobes of five lobes cools, and can extend bar magnet service life.Reducing bar magnet from top to bottom, from large to small ring to be contained in around asymmetric round tube body and to be wrapped up by tetrafluoro pillar, reducing bar magnet can arrange at the two poles of the earth, and as nine millimeters, top or seven, five millimeters, bottom is six millimeters or four, two millimeters, the utility model is seven millimeters, top, four millimeters, bottom; Also can three grades of arrangements, as nine millimeters, top or seven, five millimeters, seven millimeters, middle part or six, five millimeters, six millimeters, bottom or four, two millimeters, also can gradual change arrangement, and namely top is maximum, and bottom is minimum to be arranged in order.Conventional diameter of steel tube arrangement mode corresponding to bar magnet specification is as following table (empirical value):
It is conventional that diameter of steel tube is corresponding with bar magnet specification shows
Positioning sleeve, its upper front end is shaped with effluent trough 6, and positioning sleeve is used for shutoff fixed magnetic core and tetrafluoro pillar and derives cooling water.
Operation principle of the present utility model is:
The utility model is applicable to produce small-bore steel pipes with straight, best results in diameter 30 to 200 millimeters.
Make: when making impedor body, same specification impedor, the comparable former impedor body diameter of its impedor body is bigger, remains unchanged to keep enough intensity with the sectional area of impedor body after ensureing to retrofit; Will the assembling position of bar magnet and asymmetric round tube body, making section was upper profound moon shape, so that top assembling larger diameter bar magnet, bottom assembling small diameter bar magnet.Assembling: tetrafluoro protective pipe sleeve is installed on impedor body, the bar magnet of dimension to be put in tetrafluoro pillar and is made bar magnet ring be rolled in asymmetric round tube body by limit cover rim, bar magnet assembling principle is top major diameter, downward diameter progressively reduces, the steel pipe of different size, corresponding bar magnet specification is shown in " conventional diameter of steel tube is corresponding with bar magnet specification show "; Positioning sleeve cover is installed on impedor body, and magnetic core and tetrafluoro pillar are fixed on draw rod attachment part, with screw, positioning sleeve is fixed to the location division of impedor body.When carrying out welding production, because the magnetic core of the powerful impedor of the asymmetric magnetic core of the utility model is the asymmetric magnetic core be made up of reducing bar magnet, top bar magnet diameter is larger, bottom bar magnet diameter is less, under the prerequisite ensureing impedor bulk strength, steel tube surface induction reactance can be made to change from small to big from bottom to up, top induction reactance is made to reduce powerful electric current formed length of penetration to greatest extent, the induced-current of steel tube surface is made farthest to gather weld bond place, the building-up effect of magnetic core to steel tube surface electric current is made to reach optimum degree, thus significantly reduce power consumption, greatly improve speed of welding.Production practices are known, use the powerful impedor of this asymmetric magnetic core, when energy-conservation 10, still can improve nearly one times of speed, as produced 73*6.75 steel pipe, originally input current is when 540 kilowatt hour, welding 11 meters per minute of the speed of a motor vehicle, now, input current 480 kilowatt hour, 20 meters per minute of welding tractor scooter, when energy-conservation 20 percent, still can improve nearly one times of speed, benefit is extremely obvious.
In steel pipe processing process, cooling water flows to magnetic core from the intrinsic impedor mesopore of impedor through water hole, releases, magnetic core is cooled from the effluent trough of positioning sleeve leading section; Because bar magnet cross section is that five lobes are quincunx or six lobes are quincunx, is convenient to cool, effectively can keeps magnetic, and can prevent and avoid bar magnet Yin Wendu too high and burst apart, extend bar magnet service life.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
