Description
Technical field
The present invention relates to increases material manufacturing technology field, and in particular to a kind of purification system for metal 3D printer.
Background technology
Metal 3D printing technique controls optical-fiber laser its curing molding is formed three-dimensional using powder as material, by computer
Model, without cutter or frock clamp, it is all to have that shaping speed is fast, part accuracy is high, surface quality is excellent, materials application is extensive etc.
More advantages, turn into that current development is most fast and one of 3D printing technique of successful commercialization, be widely used in mould, automobile,
Checking is examined in product prototype manufacture, performance test and the design in the fields such as household electrical appliances, medical treatment, dentistry, jewellery, jewelry, is greatly carried
High new product development speed, reduces development cost, enhances market competitiveness of enterprises, show wide market prospects.
At present, all metal 3D printers are all run in the ring mirror of low oxygen content, for example no decontaminating column is set
Standby, oxygen content can only control thousands of ppm, if dropping to tens, it is necessary to take longer for, fall below and also be difficult to keep for a long time
Tens ppm, there is decontaminating column, and the time that oxygen content is controlled can for a long time within 80ppm and needs to spend can be very short,
For active metal such as：Aluminium alloy, titanium alloy etc., it is necessary to good quality can just be produced by being printed in very low oxygen content,
Too high oxygen level occur nodularization, oxidation, even influence part make, oxygen content number black smoke can all occur, influence part
Forming accuracy and quality.
The content of the invention
In order to solve the above technical problems, we have proposed a kind of purification system for metal 3D printer, which reduce
Oxygen content in forming room, the forming accuracy and quality of part is effectively ensured.
To reach above-mentioned purpose, technical scheme is as follows：
For the purification system of metal 3D printer, it includes forming room, in addition to pressure gauge, oxygen instrument, control system,
Gas cylinder, circulating fan and purifier, the pressure gauge, control system and oxygen instrument are connected with forming room, the gas cylinder
Gas outlet be connected by intake valve with the forming room, the gas outlet of the circulating fan is connected with the forming room,
The gas outlet of forming room one passes through purge valve respectively by air bleeding valve and contact air, another gas outlet of the forming room
It is connected with circulating valve with purifier and circulating fan, the gas outlet of the purifier is connected with the circulating fan.
Preferably, the forming room is with also connecting a Rose Box between purge valve and circulating valve.
Preferably, control system is PLC.
Preferably, the purifier is decontaminating column.
Pass through above-mentioned technical proposal, the present invention is used for the purification system of metal 3D printer, by excluding in forming room
Gas, and the gas poured into forming room after deoxygenation, the oxygen content in print procedure in the forming room of detection in real time, prevent
Only oxygen content gos up in print procedure, so as to which the precision of forming parts and quality be effectively ensured.
