Embodiment 1

[0023] figure 1 The schematic diagram of the technological process of adopting the method for repairing mold with laser fuse provided in this embodiment, the material of mold described in this embodiment is 5CrNiMo steel material; The method comprises steps:

[0024] S101, cleaning the surface of the mold to be repaired, removing oil and impurities;

[0025] S102. Preheating the mold, using a heating coil to preheat the mold;

[0026] S103. The cracks of the mold are repaired by using the wire-feeding laser cladding process, the laser spot is irradiated on the cracks of the mold, and the fed laser welding wire is clad on the cracks to repair the mold; wherein, laser cladding uses The welding wire is SKD11, the diameter is 0.6mm; the wire feeding direction is opposite to the moving direction of the mold, the angle between the wire feeding direction and the mold surface is 30°, the wire feeding speed is 3mm / s, and the mold moving speed is 1.5mm / s ;The laser power is 600W, and ...

Embodiment 2

[0030] The difference from Example 1 is that in this example, some parameters were changed in the laser cladding process steps, as follows:

[0031] In step S103, the welding wire used for laser cladding is SKD11 with a diameter of 0.8mm; the wire feeding direction is opposite to the moving direction of the mold, the angle between the wire feeding direction and the mold surface is 20°, and the wire feeding speed is 5mm / s , the moving speed of the mold is 2mm / s; the laser power is 700W, and the size of the laser spot is 6mm; among them, in the cladding repair process, the side-blowing protective inert gas is used for protection, and the direction of the inert gas injection is related to the wire feeding The direction of the injection of inert gas is the same as that of the mold surface at an angle of 50°, and the flow rate of the injection protection gas is 20L / min; among them, the size of the mold crack is about 0.6mm.

[0032] In this embodiment, the inert gas is helium, and ...

Abstract

The invention discloses a method for adopting laser fuse wires for repairing a mold, crack defects of the mold are repaired, and the mold is made of 5CrNiMo steel or 5CrMnMo steel. The method includes the steps that (a), the surface of the mold to be repaired is cleaned to remove oil stains and impurities; (b), the mold is preheated; (c), by the adoption of a wire feeding method laser cladding technology, cracks of the mold are repaired. Through the steps, cladding layers obtained on the cracks of the mold are compact and even in texture and free of pores, inclusion and other defects. The repairing method is simple in technology, low in cost, capable of effectively repairing the cracks of the mold and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a method for repairing molds with laser fuses. Background technique [0002] Mold is an extremely important and indispensable special basic process equipment in the manufacturing industry. Mold is the basic process equipment for industrial production. The mold industry is a basic industry and an important part of the equipment industry. Developed countries attach great importance to the development of the mold industry and the research and development of mold technology. The mold industry is known as the "mother of all industries" in the world and will never decline. The United States calls it "an industry of inestimable strength"; Germany regards it as a "key industry"; Japan regards it as "the secret of the entire industrial development". The mold production process integrates precision manufacturing, computer technology, intelligent control and green manufacturing to ...
