High melting point metal electric arc spraying intelligent manufacturing system

Abstract

The invention discloses a high melting point metal electric arc spraying intelligent manufacturing system which has the advantages of reasonable structure, convenient use, high modularization degree and low cost. The system which comprises an equipment body, a 6-DOF (degree of freedom) parallel platform, a 3-DOF head, a master mold heating device and a control computer is characterized in that: the pedestal of the equipment body is provided with the 6-DOF parallel platform chucked with a master mold; the crossbeam of the equipment body is provided with the 3-DOF head; the 3-DOF head which is provided with a nozzle is opposite to a movable platform of the 6-DOF parallel platform and cooperates with the movable platform to work; the movable platform of the 6-DOF parallel platform is provided with the master mold heating device; the 3-DOF head has a feed movement in a Z-axial direction with the crossbeam along a vertical column; and the 6-DOF parallel platform, the 3-DOF head, the mastermold heating device are all connected with the control computer. The system which allows the spraying on any complex curved surface master mold matrix to be realized, and the spray processing of large master mold substrates, especially large automobile cover member substrates, to be realized, has obvious economic and social effects.

Description

technical field [0001] The invention relates to the manufacturing equipment of rapid mold shells in the field of advanced manufacturing, in particular to an intelligent manufacturing system of high-melting-point metal arc spraying. Background technique [0002] Metal arc spraying rapid molding technology is a molding technology based on "replication". It uses a physical model (or prototype) as the master mold, uses the arc as the heat source, and atomizes the molten metal material through high-speed airflow. , and make it spray and deposit on the surface of the master mold to form a dense metal shell with a certain thickness, that is, the mold shell. The mold shell accurately copies the shape of the prototype and obtains the required mold cavity. After completing post-processing processes such as reinforcement, demoulding, and polishing, the rapid manufacturing of the mold can be completed. After the arc spraying mold is manufactured, it generally does not require additiona...

Problems solved by technology

The characteristic of this robot is that the machine bed, column, and beam are used as supporting parts, and the processing surface trajectory of the nozzle is formed according to the series kinematics principle of X, Y, and Z coordinate motion superposition, but the motion accuracy of the nozzle of this series robot is that each moving component Simple linear accumulation, so the motion accuracy is low, the reliability is poor, the control mechanism is complex, the structure is complicated, the weight is large, and the degree of modularization is not high, which seriously restricts the popularization and application of the rapid manufacturing process of large and complex molds
