Problems solved by technology

[0003] Traditional electrodeposition repairs and remanufactures metal parts. For large-scale parts, electrodeposition can only simply copy the deposition surface information, and due to the large area size, the deposition repair efficiency is low due to the influence of current density; for complex structural parts, immersion During plating, the cathode must sink into the plating solution, which cannot be covered, and it is difficult to achieve direct electrodeposition repair and forming of internal complex parts

Embodiment 1

[0029] Such as figure 1 As shown, this embodiment provides an electrochemical additive repair and remanufacturing method for damaged metal parts, which includes steps S1-S5. Each will be described below.

[0030] Step S1: Perform 3D scanning on the damaged part, and combine with the original 3D solid model of the part to obtain a 3D solid model of the defective part.

[0031] It should be noted that, in step S1, before performing three-dimensional scanning on the damaged part, it needs to be cleaned first. Usually, the original 3D solid model data of the part will be kept in records, and the 3D solid model of the defective part can be obtained by using computer software based on the scanned 3D solid model of the damaged part and the original 3D solid model of the part.

[0032] Step S2: Slicing and layering processing is performed according to a certain thickness, and the three-dimensional solid model of the defective part of the part is divided into multiple two-dimensional...

Embodiment 2

[0047] In this embodiment, an electrochemical additive repair and remanufacturing method for damaged metal parts is provided, and the specific process is as follows:

[0048] Smooth out the damaged part of the part.

[0049] The 3D scanning of the remaining part is carried out, combined with the comparison of the overall 3D size of the part, the 3D solid model of the defective part of the part is obtained.

[0050] Slicing and layering software is used to slice and layer the model according to a certain thickness, and the layer thickness is 0.2mm / layer to generate a slice file, which is to convert the three-dimensional information of the part into a series of two-dimensional graphic information.

[0051] The lithography machine reads in the corresponding slicing file, and cuts out the mask plate reflecting the two-dimensional contour information.

[0052]Use 100#, 200#, 600#, 800#, 1500#, 2000# sandpaper to polish the surface of the damaged part in turn, and then rinse it wit...

Abstract

The invention provides an electrochemical additive repairing and remanufacturing method of a damaged metal part. The method comprises the following steps of: step S1: performing three-dimensional scanning on the damaged part, and obtaining a three-dimensional entity model of a defective portion of the part according to an original three-dimensional entity model of the part, step S2: performing hierarchical slicing treatment according to certain thickness, dividing the three-dimensional entity model of the defective portion of the part into a plurality of two-dimensional graphs that are sequentially superimposed and have certain thickness, step S3: manufacturing a mask with a corresponding shape and thickness according to the two-dimensional graphs, and step S4: depositing a metal graph layer corresponding to the mask on the damaged part layer by layer by an electrochemical deposition method till a three-dimensional metal entity of the defective portion of the part is formed on the damaged part. The electrochemical repairing method of the metal part can achieve precise and quick repairing of the damaged metal part.

Description

technical field [0001] The invention belongs to the field of additive manufacturing, and in particular relates to an electrochemical additive repair and remanufacturing method for damaged metal parts. Background technique [0002] Existing additive repair and remanufacturing methods such as laser, plasma, and electric arc are difficult to meet the needs of in-situ accompanying maintenance repairs due to heat input and equipment usage requirements. Electrodeposition repair and remanufacturing technology is widely used in the repair and remanufacturing of metal damaged parts because of its simple structure, portability, and no heat input that will not cause deformation of the part matrix. [0003] Traditional electrodeposition repairs and remanufactures metal parts. For large-scale parts, electrodeposition can only simply copy the deposition surface information, and due to the large area size, the deposition repair efficiency is low due to the influence of current density; for...
