Abstract

The invention discloses a method for spray welding of nickel base alloy powder on a surface of a glass mold puncher pin with copper alloy as a base metal substrate, and belongs to the technical field of glass mold auxiliary component processing. The method comprises the following steps: selecting a base metal substrate, selecting welding materials, carrying out surface preprocessing, carrying out spray welding, carrying out heat treatment and carrying out finish machining. According to the technical scheme, a nickel base alloy layer and the contact end of glass melt of the copper alloy substrate are made to reflect ideal metallurgical bonding effects, the glass mold puncher pin is reliably guaranteed to have excellent corrosion resistant performance, hardness and heat dispersion performance, the situation that the nickel base alloy layer peels off in a using process cannot occur, and the high machine speed requirements of a bottle-making machine can be met. Due to the fact that manual spray welding is not necessary, the method has the advantages of being high in efficiency and reducing labor intensity of workers. Due to the fact that the service life of the glass mold puncher pin can be obviously prolonged, the mold using cost of glass product manufacturers can be reduced.

Description

technical field [0001] The invention belongs to the technical field of glass mold auxiliary parts processing, and in particular relates to a method for spray-welding nickel-based alloy powder on the surface of a glass mold punch with a copper alloy as a parent material matrix. Background technique [0002] The function of the punch on the glass mold is well known in the industry, and it is an essential part for producing glass containers such as glass bottles by the blow blow method. When a pair of opposing half-molds (customarily called half-molds in the industry) are closed, the molten glass is introduced into the cavity of the half-mold, and the high-temperature glass frit in the molten state will be placed in the first mold. The punch in the half mold cavity is completely or partially (depending on the different glass container products) wrapped, and then the punch is rapidly cooled by the punch cooler in the punch cavity of the punch, so that the previously wrapped on ...
