Problems solved by technology

At the same time, during the repeated mold opening and closing process of the glass mold, due to impact and extrusion, the seam line, upper and lower joints of the mold will be damaged and rough, which will affect the quality of the glass product. Therefore, according to the characteristics of the use environment of the glass mold, In order to improve its service life and the quality of glass products, it is necessary to strengthen the corresponding position of the glass mold to improve its high temperature resistance, wear resistance, oxidation resistance and thermal fatigue resistance.
[0003] Traditional glass mold performance strengthening methods include: manual arc surfacing, manual flame spray welding, plasma surfacing, etc. Although these methods and m

Example Embodiment

[0028] Example 1

[0029] In laser cladding a copper alloy beer bottle mold (blank mold), for example, glass DETAILED DESCRIPTION First mold die nickel-base alloy powder laser cladding process embodiment A copper alloy, comprising the steps of:

[0030] A), a pre-cavity, the workpiece blank mold into the mold surface and the upper and lower interfaces seam type milling machining, welding milled groove, slot size control, laser cladding to be obtained. Overpress this example, the vertical dimensions of the interface and the weld groove as figure 1 , 2 Indicated. First after notching die which a workpiece such as image 3 Indicated.

[0031] B), before the laser cladding processing: cleaning the weld to be laser cladding a workpiece, deburring and oil.

[0032] C), the three-dimensional model is introduced into a glass mold Robotmaster offline programming software, modeling cladding trajectory generation program, and then downloaded to a teaching program of the robot system.

Abstract

The invention relates to a process for laser cladding of nickel-based alloy powder on a copper alloy primary mold glass mold. The process comprises the following steps that a cavity is pre-machined, and specifically, welding grooves are formed in the forming mold and primary mold joint surfaces and upper and lower connectors of the mold in a turn-milling mode according to requirements; pre-treatment is conducted, and specifically, burrs and greasy dirt in the groove openings are cleaned through a brush; track programming is conducted by adopting off-line programming software to generate a motion track program; laser cladding is conducted, specifically, technological parameters are set, laser cladding is conducted along a cladding groove, so that the problem that cracks and air holes are prone to being generated due to laser cladding of the nickel-based alloy powder on the copper alloy glass mold is solved, and the main problems of traditional manual spray welding and plasma surfacing are solved; the nickel-based alloy strengthening of the joint surfaces and the connectors of the copper alloy mouth mold, which cannot be completed by plasma surfacing, is realized; and the working procedures of preheating, heat preservation, annealing and the like in traditional technological means such as plasma surfacing are omitted, and compared with manual spray welding and plasma surfacing, the powder consumption is greatly reduced, the production efficiency and the product quality qualification rate are remarkably improved, and the production cost is saved.

Description

technical field [0001] The invention relates to the field of glass mold processing and manufacturing, in particular to a process of laser cladding nickel-based alloy powder on a copper alloy primary glass mold, which is suitable for processing and manufacturing copper alloy glass molds (molding and primary molds). Background technique [0002] In the manufacturing process of glass products, the temperature of the molten glass water is as high as 1100°C, and the glass mold has been in contact with high-temperature glass water for a long time, which requires high temperature resistance and good oxidation resistance. At the same time, during the repeated mold opening and closing process of the glass mold, due to impact and extrusion, the seam line, upper and lower joints of the mold will be damaged and rough, which will affect the quality of the glass product. Therefore, according to the characteristics of the use environment of the glass mold, In order to improve its service l...
