Abstract
A coaxial powder-feeding nozzle with water cooling and guided air protection relates to a part of auxiliary laser cladding equipment, in particular to a coaxial powder-feeding nozzle adapted to a laser cladding powder feeder. The coaxial powder-feeding nozzle provided by the utility model can increase the convergence rate and keep the stability of the cladding process. The coaxial powder-feeding nozzle comprises a connecting base, and is characterized in that a channel base is arranged under the connecting base; a conical beam channel, the opening of which is positioned on the bottom, is arranged under the center of the base; the conical beam channel consists of a conical powder channel and a conical air flow channel; the opening of the conical powder channel is positioned on the bottom; a closed circular conical cooling water channel is arranged outside the conical air flow channel; and the conical powder channel and the conical air flow channel are respectively connected with a powder-feeding outlet and an air supply outlet on the base.
Description
Technical field:
The utility model relates to parts of laser melting coating auxiliary equipment, concrete is the coaxial powder-feeding nozzle that adapts to the laser coating and powder feeding device.
Background technology:
Cladding powder feeder synchronous powder feeding system method is comparatively advanced at present and uses wider a kind of method.Wherein paraxonic powder feeding, because the outlet of powder and the outlet apart from each other of light, and can not occur blocking the powder feeding mouth because of powder fusing too early; Therefore, the paraxonic powder feeding obtained using widely at the initial stage that laser melting coating is shaped fast.The size and the performance of the quick forming requirements cladding layer of laser melting coating are consistent along all directions, and the paraxonic powder-feeding nozzle only is fit to the motion of linear track, be not suitable for the motion of complicated track, the paraxonic powder-feeding nozzle can not guarantee that cladding layer is consistent with performance in the size of all directions, so can't satisfy instructions for use in laser fast forming.
The utility model content:
The purpose of this utility model is exactly at the problems referred to above, and a kind of coaxial powder-feeding nozzle that compiles rate, the band water-cooled that keeps cladding process stability and directional later exhaust protection that improves is provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises Connection Block, the below of its structural feature Connection Block is the base of passage, the below at base center is the conical shaped beam passage that is opened on the bottom, the conical shaped beam passage is from the inside to the outside for being opened on conical powder channel, the conical gas channel of bottom, conical gas channel is outward the conical cooling-water duct of closed ring type, and conical powder channel, conical gas channel link to each other with the powder feeding mouth on the base, air outlet respectively.
The beneficial effects of the utility model:
Because the utility model adopts conical gas channel, by the guiding air-flow, improved the rate of compiling of powder, again the molten bath is protected simultaneously, improved the direct accuracy of manufacture of laser.
The utility model adopts closed conical cooling-water duct, makes nozzle of the present utility model remain lower temperature in the course of the work, has prolonged the stability that has kept cladding process service life again.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
The utility model comprises Connection Block 9, the below of Connection Block 9 is the base 8 of passage, the below at base 8 centers is the conical shaped beam path 10 that is opened on the bottom, the conical shaped beam path 10 is from the inside to the outside for being opened on conical powder channel 4, the conical gas channel 5 of bottom, be the conical cooling-water duct 6 of closed ring type outside the conical gas channel 5, conical powder channel 4, conical gas channel 5 link to each other with the powder feeding mouth 12 on the base 8, air outlet 7 respectively.
The bottom opening of conical powder channel 4, conical gas channel 5 is a narrow annular channel 1,2, makes powder, air-flow that the better property compiled be arranged.
According to cladding welding needs, prevent the influence of powder carrier gas to the cladding welding, between the upper end of conical powder channel 4 and conical shaped beam path 10, be provided with relief port 11, powder draws off thus, the assurance welding quality.
Be provided with spout 3 in the bottom of conical shaped beam path 10, can prolong the service life of the utility model nozzle.
Below in conjunction with a description of drawings course of action of the present utility model:
Laser beam converges at welding focus place by the output of conical shaped beam path 10; Powder comes together in welding focus place through conical powder channel 4 outputs, reaches the effect that converges synchronously with laser beam, realizes the synchronous powder feeding system cladding.
Protection gas can be sent by conical gas channel 5, deliver to laser beam, powder focus concentric circumferences scope in, form a protection chamber around the welding focus, protection welding process material can be not oxidized.
Implantation temperature is the circulating water about 15 ℃ in conical cooling-water duct 6, prevents overheated stifled powder or the damage that causes nozzle of nozzle of the present utility model in the process.
