Description
technical fieldthe coil type electromagnetic mixing apparatus that assisted titanium Alloy by Laser deposition is repaired, belongs to technical field of material formation.
background technologytwentieth century to be born the core technology of laser deposition renovation technique the seventies: laser melting and coating technique, enters the eighties, obtains fast development.Due to this technique have easy and simple to handle, pollution-free, material use efficiency is high, with short production cycle, and the advantage such as the reparation being particularly suitable for baroque difficult-to-machine metal part, be therefore widely used in the field such as Aeronautics and Astronautics, boats and ships based on difficult-to-machine materials such as titanium alloys.In titanium alloy laser deposition repair process, repair district's profile pattern poor, it is the major reason affecting repairing quality that interior tissue exists the technical problems such as pore, lack of fusion, crack defect and unrelieved stress are large, in order to improve repairing effect, improve repairing quality, usually by adding some specific alloy element or oxide compound, or suppress by optimizing the measures such as titanium alloy laser deposition renovation technique or improve above technical problem, but raising repair layer quality is not all made a breakthrough.
summary of the inventionin view of the defect that prior art exists, the coil type electromagnetic mixing apparatus that the purpose of this utility model is to provide a kind of compact construction, reduces unrelieved stress, improves the assisted titanium Alloy by Laser deposition reparation of repairing quality.
For achieving the above object, the technical solution that the utility model adopts is: the coil type electromagnetic mixing apparatus that a kind of assisted titanium Alloy by Laser deposition is repaired, electromagnetic mixing apparatus outside is provided with ruhmkorff coil, four copper coils be wrapped on iron core are distributed in around laser powder-feeding nozzle equably, and it is coaxial with laser powder-feeding nozzle, the laser deposition reparation molten bath moment is made to be in the central position in magnetic field, laser powder-feeding nozzle top connection transformer, transformer has siliconized plate and frequency transformer, be worktable below laser powder-feeding nozzle, for fixedly laying workpiece.
Described copper coil is hollow design, middle logical recirculated cooling water.
The coil type electromagnetic mixing apparatus that a kind of assisted titanium Alloy by Laser deposition is repaired, its beneficial effect is: one is improve repairing effect well, improve repairing quality, concrete manifestation is as follows: (1) this coil type electromagnetic mixing apparatus can make repair member surface more smooth, between road, boundary obviously reduces, and sticky glutinous powder particle reduces; (2) this coil type electromagnetic mixing apparatus can suppress pore, the crack defect in interior tissue; (3) this coil type electromagnetic mixing apparatus is organized more even, and the consistent and intra-die α lamella length-to-diameter ratio of grain orientation reduces; (4) this coil type electromagnetic mixing apparatus can improve the microhardness of repair layer to a certain extent.Two is that electromagnetic mixing apparatus compact construction, the precision of present method application is higher, stable performance, meet the space requirement that test is installed, and intensity and all adjustable accurate uniform magnetic field of speed can be produced in work area, and not by the restriction of repairing workpiece size, can well play stirring effectiveness, the problem mentioned in improving environment background and defect.
Accompanying drawing explanation
Fig. 1 is the structure iron of the coil type electromagnetic mixing apparatus that a kind of assisted titanium Alloy by Laser deposition is repaired.
Fig. 1 Reference numeral is as follows: 1, frequency transformer, and 2, transformer, 3, siliconized plate, 4, laser powder-feeding nozzle, 5, ruhmkorff coil, 6, copper coil, 7, workpiece, 8, worktable.
Embodiment
With reference to the accompanying drawings the coil type electromagnetic mixing apparatus that a kind of assisted titanium Alloy by Laser deposition is repaired is described as follows below: electromagnetic mixing apparatus outside is provided with ruhmkorff coil 5, four copper coils 6 be wrapped on iron core are distributed in around laser powder-feeding nozzle 4 equably, and it is coaxial with laser powder-feeding nozzle 4, the laser deposition reparation molten bath moment is made to be in the central position in magnetic field, laser powder-feeding nozzle 4 top connection transformer 2, transformer 2 has siliconized plate 3 and frequency transformer 1, be worktable 8 below laser powder-feeding nozzle 4, for fixedly laying workpiece 7.
Titanium alloy laser repairing completes on workpiece 7, and workpiece 7 is fixed on worktable 8, and the size of change received current and frequency just can adjust size and the slewing rate of rotatingfield, thus obtain different mixing effects; Received current frequency is realized by frequency transformer and then reaches the speed of rotation changing rotatingfield; The size of received current is regulated the size of input voltage by transformer and then is changed size of current and reaches the object changing magneticstrength; Electromagnetic mixing apparatus is arranged on laser powder-feeding nozzle 4, and workpiece 7 is placed on the worktable 8 in the middle of magnetic pole; The alternating current of phase differential 90 degree is passed in ruhmkorff coil, copper coil 6 can produce an alternate rotary magnetic field, can produce induced current when him during the metallic solution of its cutting laser molten pool, the metallic solution of current-carrying and magnetic field interaction produce to act on and liquid horizontally rotate electromagnetic force.
