Electric arc material increase manufacturing method based on failure part of hot working mold

Abstract

The invention discloses an electric arc material increase manufacturing method based on a failure part of a hot working mold. The method comprises the steps of removing dust and rustiness from the failure part of the original hot working mold, gouging the failure part of the original hot working mold by a carbon arc air gouging method, measuring the dimension of a new hot working mold with a laser scanner to create a three-dimensional model of the new hot working mold, performing boolean calculation on the three-dimensional model of the new hot working mold and a three-dimensional model of the original hot working mold with three-dimensional modeling software to obtain a three-dimensional model of the failure part, performing slicing and feeding route planning on the three-dimensional model of the failure part with programming software to obtain a feeding route of the failure part, performing route reversion on the feeding route of the failure part with 3D Automate software to obtain a stacking route of the failure part to generate a corresponding stacking program, and allowing a welding robot to perform surfacing and repair on the failure part of the new hot working mold via the stacking program. The method has the advantages of low manufacturing cost, high production efficiency, stable quality of the manufactured hot working mold and the like.

Description

technical field [0001] The invention belongs to the technical field of metal forming and manufacturing, and in particular relates to an arc additive manufacturing method based on the failure part of a hot working die. Background technique [0002] Hot work dies are a type of key spare parts that consume a lot in the forging industry. Their quality and service life directly affect production efficiency, part quality and production costs. Due to the harsh working conditions of the hot work mold, it is prone to failure in the form of cracking, wear and deformation. During the entire use period of the hot work mold, the real working part is the cavity, and the part accounting for 80-90% of the total weight of the mold is likely to be scrapped due to local defects in the mold cavity, causing great economic losses. [0003] At present, scrapped hot work molds are generally repaired by surfacing welding technology, but this method is prone to disadvantages such as poor working con...

Due to the harsh working conditions of the hot work mold, it is prone to failure in the form of cracking, wear, deformation, etc.

During the entire use period of the hot work mold, the real working part is the cavity, and the part accounting for 80-90% of the total weight of the mold is likely to be scrapped due to local defects in the mold cavity, causing great economic losses

[0003] At present, scrapped hot work molds are generally repaired by surfacing welding technology, but this method is prone to disadvantages such as poor working conditions, waste of materials, high production costs, and low production efficiency; at the same time, the welding level of welding workers varies. Overlay welding is carried out on the cracked parts, worn parts and deformed parts of the hot work mold. The quality of the hot work mold after overlay welding is unstable due to the uneven level of welding workers.
