Description
(1) technical field
The utility model relates to the powder conveying device that a kind of laser is made the field again.
(2) technical background
At present, laser is made as a kind of novel material processing method again and is widely used in the every field that industry is made.The laser automatic transport mode of manufactured materials again mainly contains two kinds of powder feeding formula and wire feed formulas.Domestic existing powder conveyer, powder feeder such as for example scraper-type, volume be spiral is because its design reasons has exacting terms to powder size and humidity.If do not adopt gas delivery, can cause powder feeding rate inhomogeneous, powder can not well converge in the laser facula place, and causes the stifled powder at the powder-feeding mouth place especially easily.If adopt gas delivery, cause powder agglomates easily and stifled powder, the phenomenon such as interrupted, stuck because powder advances in an axle turning motion vice division chief also appears in the transmission rig of powder feeder easily.Chinese patent 0224563.5 discloses a kind of laser cladding powder feeder, utilize the hub-type powder feeding wheel that the powder that falls in the one side powder storage hopper is sent into the meal outlet of opposite side, the deficiency of this device is: the bearing place that the hub-type powder feeding wheel is connected with housing is interrupted, stuck because of advancing powder easily.
(3) summary of the invention
The purpose of this utility model provides a kind of synchronous powder feeder for laser reproduction, and the axle turning motion pair of its transmission rig can interrupted, stuck phenomenon not occur because of advancing powder.
A kind of synchronous powder feeder for laser reproduction comprises shell; Kernel is housed in the shell, the powder-storage bin that is communicated with kernel is equipped with in the shell top, the powder delivery device that is communicated with kernel is equipped with in the shell below, rotating shaft runs through described kernel and is installed on the shell by bearing, rotating shaft is connected with drive-motor, is positioned at that key is connected with the powder feeding running roller in the rotating shaft of kernel, and the upper end of powder feeding running roller is corresponding with the outlet of described powder-storage bin, the lower end of powder feeding running roller is corresponding with the inlet of described powder delivery device, is evenly equipped with the groove that holds powder on the periphery of powder feeding running roller; Have the ventage that kernel is communicated with atmosphere on the described shell.
Further, O-ring seals is equipped with in the junction of described rotating shaft and kernel.
Further, described powder-storage bin is by being threaded on the described kernel.
Further, described powder delivery device is a funnel.
Technical conceive of the present utility model is: auxiliary delivering gas is sent into metal-powder from powder-storage bin, and be stored in the groove of powder feeding roller wheel surface, motor-driven rotatable shaft is rotated, metal-powder is along with the rolling of powder feeding running roller is fallen in the funnel, and the metal-powder that is mixed with gas is sent through the pipeline of funnel lower end.The utility model is by being provided with a kernel in the enclosure, and loads onto sealing-ring in the junction of kernel and rotating shaft, thereby gas and powder and bearing are kept apart, and powder can not enter in the bearing, therefore interrupted, stuck phenomenon can not occur.In addition, because kernel communicates with atmosphere, rotating shaft can not block commentaries on classics because of the obstruction of powder yet.
The beneficial effects of the utility model are: (1) working stability is reliable, and the axle turning motion pair of transmission rig can interrupted, stuck phenomenon not occur because of advancing powder; (2) powder feeding is evenly also controlled continuously, and powder size adaptability is strong.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the sectional view of powder feeding running roller of the present utility model.
(5) embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1-2: a kind of synchronous powder feeder for laser reproduction, comprise shell 5, kernel 8 is housed in the shell 5, the powder-storage bin 3 that is communicated with kernel 8 is equipped with in shell 5 tops, the powder delivery funnel 9 that is communicated with kernel 8 is equipped with in shell 5 belows, rotating shaft 12 runs through described kernel 8 and is installed on the shell 5 by rolling bearing 6, rotating shaft 12 is connected with stepper-motor by shaft joint, be positioned at that key is connected with powder feeding running roller 13 in the rotating shaft 12 of kernel 8, the upper end of powder feeding running roller 13 is corresponding with the outlet of described powder-storage bin 3, the lower end of powder feeding running roller 13 is corresponding with the inlet of described powder delivery funnel 9, be evenly equipped with the groove 7 that holds powder on the periphery of powder feeding running roller 13, described groove 7 is a V-shaped groove; Have the ventage 14 that kernel 8 is communicated with atmosphere on the described shell 5.Described rotating shaft 12 is equipped with double O-ring seals 10 with sealed gas and powder with the junction of kernel 8.
Described kernel 8 is provided with kernel lid 4, and the lower end of described powder-storage bin 3 is by being threaded on the described kernel lid 4, and the spacing between powder feeding running roller 13 and the kernel lid 4 can be controlled by the rotation screw thread.The storehouse lid 2 that has inlet mouth 1 is installed on the powder-storage bin 3, and inlet mouth 1 and inlet mouth 14 equate gas (the auxiliary conveying with gas Ar or the N2) pressure in powder-storage bin 3 and the kernel 8 by T-valve.
Shell 5 links to each other by the focusing system of bolt with the laser remanufacturing system, realizes that the powder and the laser facula of delivery system is synchronous.
During work, at first by opening auxiliary delivering gas (Ar or N2), auxiliary delivering gas is sent into metal-powder from powder-storage bin 3, and be stored in the groove 7 on powder feeding running roller 13 surfaces, motor is rotated under given rotating speed, metal-powder is along with the rolling of powder feeding running roller 13 is fallen in the powder delivery funnel 9, and the metal-powder that is mixed with gas is sent through the pipeline of powder delivery funnel 9 lower ends, can realize that metal-powder is transported in the focusing system of making again with given speed.
The utility model is by being provided with a kernel in the enclosure, and loads onto sealing-ring in the junction of kernel and rotating shaft, thereby gas and powder and bearing are kept apart, and powder can not enter in the bearing, therefore interrupted, stuck phenomenon can not occur.In addition, because kernel communicates with atmosphere, rotating shaft can not block commentaries on classics because of the obstruction of powder yet.
