Description
Technical field
The utility model relates to cladding laser surfaces and rapid laser-shaping technique, specifically, and the powder feeding technology in cladding laser surfaces and the laser fast shaping.
Background technology
Present existing powder feeder, because the powder amount in the powder tube is a ccasual, the pressure that lower floor's powder is subjected to also is ccasual, and the density of sending powder is uncertain, and the quality of sending powder has randomness.The cladding layer thickness that obtains is just inhomogeneous.
Summary of the invention
The purpose of this utility model is to provide a kind of can obtain that cladding layer is continuous, bed thickness evenly, boundary line powder feeder clearly.
The utility model provides a kind of vertical whirlwind spiral synchronous powder feeder, it is characterized in that: mainly by the powder tube, motor 1, airduct 10, tube cell is formed, the powder tube is from top to bottom by last powder tube 4, die sleeve 6 and following powder tube 8 constitute, motor 1 places on the powder tube, the main shaft of motor 1 reaches for 3 times in the powder tube, be connected to spiral conveyor rod 5 on the main shaft 3, conveying lever 5 reaches down powder tube 8 from last powder tube 4 by die sleeve 6, following powder tube 8 is connected to tube cell II13 by joint 9, following powder tube 8 relative both sides are equipped with whirlwind nozzle 11 respectively and are connected to tube cell I12, the other end of tube cell I12 feeds the top of going up powder tube 4, is connected to airduct 10 on the whirlwind nozzle 11.
Feed pressure gas for 8 li at following powder tube, through whirlwind nozzle 11, produce whirlwind, allow powder revolve and float, too much powder is got back to powder tube 4 through tube cell I12, it is constant that pressure that powder is subjected to is preserved, and it is constant that the powder density of sending keeps, with obtain bed thickness evenly, continuously, boundary line cladding layer clearly.
The vertical whirlwind spiral synchronous powder feeder that the utility model provides, powder filler port is arranged at the top of powder tube 4 on it, opens port lid, can add powder.
The vertical whirlwind spiral synchronous powder feeder that the utility model provides, pressure-relief valve 2 is arranged at the top of powder tube 4 on it, avoids 4 li pressure of powder tube excessive, the pressure that keeps relative stability.
The vertical whirlwind spiral synchronous powder feeder that the utility model provides is equipped with control cock 7 on the pipeline of its tube cell I12, to regulate down the pressure of 8 li in powder tube.
The vertical whirlwind spiral synchronous powder feeder that the utility model provides, its motor 1 is a stepping motor 1, and is adjustable continuously with the size that realizes powder sending quantity better, it is short that response time is opened, stops in powder feeding.
The vertical whirlwind spiral synchronous powder feeder that the utility model provides, its tube cell II13 other end is connected to nozzle, to realize even powder feeding better.
The vertical whirlwind spiral synchronous powder feeder that the utility model provides, its advantage is: can obtain bed thickness evenly, continuously, boundary line cladding layer clearly, the powder feeding process is continuous, the size of powder sending quantity is adjustable continuously, it is short that response time is opened, stops in powder feeding.
Description of drawings
Fig. 1 is the structural representation of vertical whirlwind spiral synchronous powder feeder.
The specific embodiment
Embodiment 1
The structure of vertical whirlwind spiral synchronous powder feeder as shown in Figure 1, by the powder tube, motor 1, airduct 10, tube cell is formed, the powder tube is from top to bottom by last powder tube 4, die sleeve 6 and following powder tube 8 constitute, motor 1 places on the powder tube, the main shaft of motor 1 reaches for 3 times in the powder tube, be connected to spiral conveyor rod 5 on the main shaft 3, conveying lever 5 reaches down powder tube 8 from last powder tube 4 by die sleeve 6, following powder tube 8 is connected to tube cell II13 by joint 9, following powder tube 8 relative both sides are equipped with whirlwind nozzle 11 respectively and are connected to tube cell I12, the other end of tube cell I12 feeds the top of going up powder tube 4, is connected to airduct 10 on the whirlwind nozzle 11.Powder filler port and pressure-relief valve 2 are arranged at the top of last powder tube 4, and control cock 7 is housed on the pipeline of tube cell I12, and motor 1 is a stepping motor, and the tube cell II13 other end is connected to nozzle.
When vertical whirlwind spiral synchronous powder feeder was worked, motor 1 drove screw shaft 5 rotations.Alloy powder in the last powder tube 4 is filled thread groove under the effect of gravity and powder bulkhead pressure, the thread groove that rotates produces downward pressure to the alloy powder in the space, powder is in the dirty powder delivery of the effect of pressure storehouse, enter down in the powder tube 8, pressure gas also enters in the following powder tube 8 with the whirlwind form under the effect of whirlwind nozzle, metal powder in the following powder tube 8 from spraying among the tube cell II13 the powder tube down, is transported to the lasing district by the powder mouth again under the effect of gravity and cyclone type pressure gas.
The powder mass flow that enters tube cell is subjected to motor speed and control cock 7 to open the common control of size.Motor 1 rotating speed is fast more, and powder mass flow is big more; It is more little that control cock 7 is opened, and powder mass flow is big more.
The whirlwind nozzle makes pressure gas along powder storehouse inwall tangent line direction ejection on the upper side down, and it is for the helical movement that the pressure gas of ejection drives metal powder granulates.The air-flow of direction applies an application force that makes progress to powder on the upper side, powder particle under the combined action of this application force and self gravitation, motion for the helical movement.Adjust the size that control cock 7 is opened, can make down metal powder in the powder tube 8 enter tube cell or turn back in the powder tube 4, and flow can be controlled.
