Embodiment Construction
[0019] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0020] See figure 1 , is a schematic structural diagram of an embodiment of a control method for improving the utilization rate of laser 3D printing and surface treatment materials in the present invention. The laser welding torch 3 is located above the workpiece 1, and the powder feeding pipe 4 feeds powder from one side of the laser welding torch 3. The purge pipe One 5 is located in front of the running track of the laser welding torch 3 and is used to clean the surface of the workpiece to be welded. The baffle 6 is located on the other side of the laser welding torch opposite to the powder feeding pipe 4 to prevent powder from splashing. The rear of the welding torch 3 running track is used to clean the surface of the workpiece after welding, and blows the unused powder into the collecting pan 8 below the workpiece. The filtering device 9 is l...

The invention relates to the technical field of 3D (three-dimensional) printing and material processing, in particular to a control method for improving laser 3D printing and surface-treatment material utilization rate. The control method is characterized in that during laser welding, powder unemployed on the surface of a workpiece is cleaned into a collecting tray below the workpiece in real time, a controller detects recycled powder amount in the collecting tray in real time, powder feeding amount is optimized and controlled in a closed loop control way according to the recycled powder amount, and utilization rate of the powder is increased. Compared with the prior art, the control method has the advantages that unemployed powder can be effectively cleaned and collected in the process of laser 3D printing and surface treatment, and material recycling is realized; powder feeding amount and powder recycling amount can be monitored and in closed loop control in real time, and control and optimization of powder utilization are realized; product quality of the finished products can be improved on the basis of reducing production cost; the control method is high in automation degree and has wide market prospect.
Description
technical field [0001] The invention relates to the technical field of 3D printing and material processing, in particular to a control method for improving the utilization rate of laser 3D printing and surface treatment materials. Background technique [0002] In laser 3D printing and surface treatment technology, the utilization rate of materials is very important. On the one hand, it refers to the proportion of the amount of materials contained in qualified products in the total consumption of materials (raw materials), that is, the used The ratio of the material to the actual consumed material indicates the degree to which the material is effectively utilized; on the other hand, it also affects the quality of the processed qualified product. The low utilization rate of the powder proves that the amount of powder fed during the processing is too high. If the material is not fused, it proves that there is a problem with the processing technology. If it is not adjusted in ti...
