Special-shaped part forming maintenance method

Abstract

The invention discloses a special-shaped part forming maintenance method which includes the steps: forming a sub-material model of a special-shaped part by a model before breakage and a base material model of the special-shaped part; virtually and integrally melting the sub-material model and the base material model of the special-shaped part in a virtual laser melting environment to obtain virtual laser melting parameters when the performance of a virtual welding seam formed in the virtual melting process meets a standard; integrally melting sub-materials and base materials of the special-shaped part by the aid of a laser melting treatment method and the laser melting parameters. According to the forming maintenance method, a virtual maintenance technology and a laser material increase manufacturing technology are combined, the structure and the performance of the special-shaped part after maintenance are as same as those of the special-shaped part before breakage, the performance of the special-shaped part after maintenance is improved, the service cycle of the special-shaped part is prolonged, and a large quantity of manpower, material resources and financial resources are saved, so that the special-shaped part is high in recycling rate, short in maintenance cycle and good in maintenance effect.

Description

technical field [0001] The invention relates to the technical field of forming and manufacturing, in particular to a forming maintenance method for special-shaped parts. Background technique [0002] At present, special-shaped parts (or components) with irregular shapes are often used in mechanical equipment. The structure of this kind of special-shaped parts is relatively complicated and requires high precision. When the parts are cracked or damaged, the method of replacing parts is usually adopted. This method Cause huge loss due to parts being scrapped, and replacing parts requires a longer production cycle and higher production costs. [0003] In addition, in the prior art, the following two maintenance methods can be adopted for the cracked or damaged special-shaped parts: [0004] 1. Composite bonding repair technology: This technology uses a viscous synthetic fiber to cover the defect area for bonding strengthening. However, this technology can only be used for crac...

Problems solved by technology

However, this technology can only be applied to the repair of cracks or worn parts, and cannot repair parts that have been broken into two parts. In addition, this technology cannot guarantee that the shape of the repaired part is consistent with the shape of the original part

[0006] To sum up, whether it is composite bonding or surfacing repair, there are shortcomings such as long repair time, deformation of special-shaped parts after repair, and unguaranteed accuracy, resulting in loss of manpower, material resources, and financial resources.
