Description

TECHNICAL FIELD

[0001] The present application relates to the glass mold processing manufacturing technical field, and particularly relates to a copper alloy mouth mold glass mold inner cavity laser cladding equipment. BACKGROUND

[0002] In the glass product manufacturing process, the temperature of the molten glass water is as high as 1100 DEG C or above, and the glass mold is in long-term contact with the high-temperature glass water, and needs to have good high-temperature resistance and oxidation resistance. In the repeated opening and closing process of the glass mold, due to the impact and extrusion, the joint line, the upper and lower interface and other positions of the mold are damaged and roughened, which affects the quality of the glass product. Therefore, according to the use environment characteristics of the glass mold, in order to improve the service life and the quality of the glass product, the corresponding positions of the glass mold need to be strengthened to improve the high-temperature resistance, wear resistance, oxidation resistance and thermal fatigue resistance and other properties. Laser cladding technology is generally used, that is, metal powder or wire is melted by heating and solidified on the surface of the base material to form a coating.

[0003] For example, a laser cladding device is disclosed in Chinese patent No. CN107627002B, which melts the guide wire on the material surface by laser to improve the high-temperature resistance, wear resistance, oxidation resistance and thermal fatigue resistance and other properties of the material. Although the performance of the material can be improved, the laser cladding is carried out by one nozzle in the cladding process, and the entire material surface needs to be cladded, which results in low cladding efficiency. For example, a double-cladding-head laser cladding metal additive manufacturing equipment is disclosed in Chinese patent No. CN108817391B, which clads the material on the workpiece surface by the double-cladding-head. The Y-direction moving mechanism is connected with the cross beam to drive the cross beam to move along the Y direction. The X-direction moving mechanism is connected with the Z-direction moving mechanism to drive the Z-direction moving mechanism to move along the X direction. The Z-direction moving mechanism is connected with the double-laser-head cladding mechanism to drive the double-laser-head cladding mechanism to move along the Z direction. Although the metal powder cladding efficiency is improved, the double-cladding-head can only move on the linear guide rail. For some planar cladding, the efficiency is relatively high, but for some cylindrical surfaces, it is not suitable, for example, laser cladding of the inner cavity of the mouth mold glass mold is obviously not suitable, and the double-cladding-head cannot be symmetrically cladded along the material, which is easy to cause relatively large thermal stress in the material.
