Mobile platform 113 moves back and forth, and realization is scraped metal powder and returned and scrapes, and striker 115 is provided on the scraper 114, described
First collision bar 116 and the second collision bar 117 are separately positioned on sintering 110 inside two sides of storehouse and corresponding with striker 115.
The feeding mechanism 12 includes that setting is being sintered 110 bottom of storehouse and the powder feeding cylinder 121 that is connected with sintering 110 inner cavity of storehouse
And the sintering that the powder feeding piston 123 that is contained in powder feeding cylinder 121 of sintering cylinder 122, one end, one end are contained in sintering cylinder 122 is living
Plug 124, the feeding conveyor 125 being connected with powder feeding cylinder 121 and sintering 122 other end of cylinder.
The powder feeding cylinder 121 and sintering cylinder 122 is fixed by screws in sintering 110 bottom of storehouse.
The scraper 114, which relatively moves platform 113, certain deflection angle, and deflection angle is positive and negative 5~10 degree preferred.
The mobile platform 113 selects vibrator platform, the vibration of certain frequency is generated at work, in scraper
114 when scraping metal powder back and forth, is shaken by high-frequency, keeps metal powder more smooth.
The door 111 is equipped with observation window, and observation window is blocked using transparent panel, facilitates operator.
Gas atmosphere inlet 1101 and waste gas outlet 1102 is respectively set in the left and right sides in the sintering storehouse 110.
Referring to fig. 4 shown in -7:
The sintering cylinder 122 is located at center, powder feeding cylinder 121 and collection cylinder 118 and is distributed in two sides, powder feeding cylinder 121 and sintering cylinder
122 sizes are identical, are inside respectively equipped with a piston, respectively powder feeding piston 123 and sintering piston 124, and piston and feeding transmit
The screw rod of device 125 is connected, and drives screw rod rotation by the stepper motor of feeding conveyor 125, and enable to move down on piston
It is dynamic.Assuming that a height of h of unit slicing layer of printer printing, when work, powder feeding piston 123 moves up kh, and wherein k value is greater than 1, due to
Powder feeding piston 123 moves up, and powder is higher by work top, and sintering piston 124 moves down h at this time, and scraper 114 is by austenite stainless
Steel material finishing is made, and knife face is straight, and powder feeding cylinder 121 is moved up to the gold for being higher by work top of ejection by powder feeding piston 123
Belong to powder to scrape to sintering cylinder 122, scraper 114 is mounted on mobile platform 113, and mobile platform 113 is vibrator, makes to scrape powder equal
It is even thick and solid.Since k value is greater than 1, a movement of scraper 114 can completely be spread sintering 122 powder of cylinder to work top, extra
Powder enters collection cylinder 118 by scraper 114 and collects.
Oversintering cylinder 122 is scraped when scraper 114 returns, metal powder is paved, is mounted on the laser 13 of 122 top of sintering cylinder
Laser beam is issued, by 14 deflection scanning of galvanometer, scan model a slicing layer under software control, metal powder welding
Together, the sintering of model current layer is completed.It, will be metal powder sintered in the aspiration channel for being equipped with dust below galvanometer 14
Smog in the process siphons away the cleaning to maintain 14 surface of galvanometer in time, while small floating dust being siphoned away.Installation in agglomerating chamber 11
There is gas pressure sensor, the aperture of aspiration channel is controlled according to pressure size.The setting of oxygen content directly controls outdoor inertia
The aperture of 11 air intake duct of gas valve and agglomerating chamber, is typically set at 0.2%, titanium alloy then needs to be set as 0.01%.
The halogen lamp 119 of heating is 500W, and power is controllable, and predominantly the metal powder of agglomerating chamber 11 is dry uses.
21 blade type of industrial PC is mounted in control cabinet 2, is externally provided touch screen, USB, keyboard and mouse, is mentioned simultaneously
For network interface, print control can be carried out with Telnet.
Dust collect plant is installed on outdoor, has two channels of disengaging.The pure argon that air inlet is 99.99%, outlet are to contain powder
The mixing argon gas of dirt and smog, is outwardly discharged after being filtered by water, and dust and smog are deposited on water tank bottom, plays environment
Protective effect.
Agglomerating chamber 11 is the closed fully sheathed case of nature, without doing vacuum sealing, by low-pressure protective gas constantly
The low oxygen content for keeping agglomerating chamber is provided.After setting oxygen content parameter, by being protected outside pressure sensor and lambda sensor control room
Protect the aperture automatic adjustment of gas valve and indoor suction pipe.Concrete methods of realizing is, when oxygen content reduces, gradually to turn down suction
The valve opening of tracheae improves the positive pressure of agglomerating chamber, is further reduced the oxygen for being mixed into agglomerating chamber, and maximum pressure is to nominal
It is not able to satisfy oxygen content requirement when 20% still, then further opens the aperture of big protective gas valve with a unit stepping, until
Oxygen content is not less than nominal value, and the valve opening for then gradually opening big air intake duct makes pressure within the scope of the 80-120% of nominal value
Oxygen content is close to setting value.
Sensor also provides triggering alarm and closes laser generator unit, prevents sensor is out of control from leading to some active gold
Metal particles such as aluminium powder deflagration accident.
The powdering structure of agglomerating chamber is completed by the scraper being fixed on stepping motor synchronous band, and scraper is by main carriage and scrapes
Item, adjustable spring return positive spring, collision bar, rocker arm and vibrator composition.When job initiation limits, collision bar top to main carriage,
Scraper goes to 0 ° by -5 °, and scraping article rises, and scraping article restores under the action of the telescopic spring at+5 °, and doctor blade holder and scraping article are returning positive bullet
Scraping article contradicts platform under the action of spring, starts to scrape powder, and when being moved to other end limit, collision bar hits scraper, is turned by 5 °
- 5 ° are arrived again to 0 °, complete back to scrape.
The above, only presently preferred embodiments of the present invention, be not limiting the present invention, it is all according to the present invention
Technical spirit trickle amendment to the above embodiments, equivalent replacement and improvement should be included in technical solution of the present invention
Within protection scope.
