Description
Technical Field
The utility model belongs to the technical field of laser cladding 3D vibration material disk technique and cutting subtract material manufacturing, concretely relates to novel metal increase and decrease material combined manufacturing equipment.
Background
In recent years, metal 3D printing achieves outstanding performance in the field of additive manufacturing, and has considerable application prospects, at the present stage, metal 3D printing equipment can finish final molding manufacturing of devices through further cutting machining after molding, a new feasible way is provided for manufacturing processes, and the application fields of the metal 3D printing equipment are spread in aerospace, medical equipment, mechanical manufacturing, electronic information industries and the like. Among a plurality of metal 3D printing technologies, the laser cladding forming technology obtains considerable results in the field of metal 3D printing, such as device forming, surface cladding repairing and processing, surface strengthening and the like. The principle is that powder is melted by acting laser on a powder flow conveyed by a nozzle, namely the laser heats metal powder, the melted powder completes the molding of a first layer according to the path of a three-dimensional model slice code, then completes the cladding of a second layer on the basis of the previous layer in the same way, and the process is repeated to complete the final three-dimensional molding. However, the surface of the formed body is not flat and can not be directly applied, so that after the material increase forming, the formed body needs to be cut by a numerical control processing device to obtain a final formed device, and thus the traditional metal 3D printing device starts to turn to the material increase and decrease integrated device.
Because common 3D printing hardware and systems (such as arduino, red rabbit and the like) cannot complete complex multi-axis control, the output power cannot meet the requirements of laser operation, and the common 3D printing hardware and systems also do not have multi-port output control factors such as powder feeding and the like, the traditional laser cladding material increasing and decreasing equipment usually adopts numerical control processing hardware and systems to realize a three-dimensional forming process, the multi-axis three-dimensional movement control and cutting processing path in the numerical control processing system is combined with the laser cladding system to realize the material increase manufacturing process, the numerical control processing system has multi-axis port output, and redundant output ports can be used for various controls such as laser control and powder feeding system. And correspondingly, the process of cutting the printed formed body is finished through another set of numerical control processing system, namely, the two sets of numerical control processing systems finish the control of the material increasing and decreasing integrated machine. However, the use of the nc processing system for a 3D printing system is costly, and many functions in the nc processing system are idle. Meanwhile, the existing laser cladding numerical control machining and forming system cannot solve the problem of the function of path optimization, and does not have a feedback regulation mechanism in the printing powder feeding and forming process, so that the problem that the direct application of a cutting road to three-dimensional forming inevitably causes some unavoidable problems is inevitable. The specific reasons are that:
firstly, when the numerical control machining system faces corner machining, the horizontal movement can be decelerated, particularly at the corner position with a non-circular angle, the deceleration is more obvious, namely, the numerical control machining system defaults to a deceleration over-bending machining mode in order to meet the requirements of a cutting machining process.
Secondly, the powder feeding system does not adjust the powder feeding speed and the powder feeding amount due to the reduction of the traveling speed.
These factors result in the incompatibility between powder feeding and printing in the whole process, which results in the poor powder fusion accumulation effect, and the accumulation problem becomes more serious when the three-dimensional forming process encounters a turning stage. However, these problems will cause uneven thickness of each layer, and especially the problems of porosity, cracking, sand inclusion (insufficient powder cladding) and the like at the corner position are more obvious, and the problems become more severe in the three-dimensional forming process layer by layer, which finally destroy the precision of the whole three-dimensional forming structure, and cause the deformation of the structure in a more complicated printing model. The final result is poor metallurgical quality of the formed body, and the mechanical properties of the formed body cannot be stably guaranteed. Meanwhile, in the subsequent cutting process, because the cutting road strength is automatically generated according to the three-dimensional model, error correction on additive manufacturing cannot be involved, so that a certain error is generated between an additive manufactured model body and a model body, an error is generated between a finished product and a planned molded body which are actually manufactured by material reduction, the precision of the final finished product is influenced, and secondary processing also inevitably increases the period and the cost of the whole process. In addition, the common material increase and decrease integrated equipment generally uses two sets of processing systems to respectively complete the material increase manufacturing process and the material decrease manufacturing process, so that the equipment cost and the operation difficulty are greatly increased.
