Description
Technical Field
The invention belongs to the technical field of additive manufacturing, and particularly relates to a material-increasing and material-decreasing four-station near-net forming device and a forming method.
Background
The material increasing manufacturing technology develops for decades, and shows great advantages compared with the traditional processing mode in the aspect of manufacturing parts with complex structures by virtue of the advantages of rapidness, flexibility, low cost and the like. The advantages of short manufacturing period, high automation, less material consumption and the like well make up for the defects of the traditional manufacturing process, so that the technology is more and more widely applied. However, due to the influence of the size of powder, the size of a laser focusing spot and a discretization layering technology, the geometric dimension precision and the surface smoothness of the produced metal part are not ideal, so that the external dimension of the formed part cannot be directly applied, and particularly, the non-powder bed near-net forming type additive manufacturing is not realized. The traditional numerical control machining technology has the characteristics of high precision, high surface quality and the like, and can make up for the problems. Therefore, after the part is formed by the additive manufacturing method, machining allowance or polished surface is often milled by using a subtractive manufacturing method such as turning, milling, grinding and the like, so as to achieve the required surface quality and dimensional accuracy of the part. In order to realize high-precision additive manufacturing, an additive manufacturing technology and cutting processing are combined, so that the respective advantages of the two technologies are fully exerted, and the effective combination of the additive processing technology and the material reducing processing technology has wide application prospect.
Conventional additive manufacturing processes that are performed prior to processing by a subtractive machine undoubtedly reduce production process efficiency and increase operational complexity. In order to improve the forming efficiency, improve the part precision and really apply the additive manufacturing technology to the actual industrial field, the additive manufacturing process and the material reducing machining process are combined into the same equipment, so that the metal part has better surface precision in the forming process, and the operations of milling, polishing and the like of an inner hole, a hollow part and other parts difficult to machine of the part in the additive manufacturing process can be realized, thereby greatly improving the applicability of the additive manufacturing technology in the production and machining of precise parts.
The existing material increase and decrease integration technology is generally as follows: 1. the additive manufacturing module and the subtractive manufacturing module adopt the same three-coordinate or robot structure, and the machining head of additive manufacturing and the cutter module of subtractive manufacturing are repeatedly replaced in the part forming process to realize the interactive forming of additive and subtractive manufacturing, for example, the technical scheme disclosed in the Chinese patent publication CN 109202290A. 2. The material adding module and the material reducing module are respectively controlled by one three-coordinate robot, such as the technical solutions disclosed in chinese patent publications CN 109175367 a and CN 109262268A, or the material adding module and the material reducing module are respectively controlled by two robots directly, such as the technical solution disclosed in chinese patent publication CN 108581490 a. 3. The material adding module and the material reducing module are respectively controlled by two three coordinates, for example, the technical scheme disclosed in the Chinese patent publication CN 105817625A.
The following problems are present in all the above prior arts: 1. the material increasing module and the material reducing module only work one time, and the forming efficiency is low due to the fact that two stations are repeatedly switched; 2. the material increase module and the material reduction module are repositioned each time when working, and particularly, the position center of material increase manufacturing and the axis of material reduction manufacturing are deviated due to installation or repeated positioning errors of a material increase module processing axis and a material reduction module main shaft axis which are installed on a robot movement mechanism, so that the position coordinate change of a forming point is brought, and the forming failure is easily caused due to inaccurate positioning; 3. the robot running mechanism has good flexibility and poor rigidity, and processing deviation is easy to generate in the forming process, particularly in the material reducing processing process, so that the processing precision does not reach the standard or the forming fails; 4. in the additive manufacturing process and the subtractive manufacturing process, powder, chips and the like cannot be cleaned in time on the same platform, so that subsequent procedures are interfered, and forming failure is caused.
