Description
Technical Field
The invention relates to the field of small-opening pressure-blown glass dies, in particular to a process for manufacturing cobalt-based alloy powder through laser cladding of a punch of a small-opening pressure-blown glass die.
Background
In the production process of the small-opening pressure-blowing method of the glass bottle, as the punch head needs to be frequently in direct contact with high-temperature glass solution and is punched and rubbed with the glass solution at a high speed, the vulnerability of the punch head of the small-opening pressure-blowing glass mould is determined, and in order to prolong the service life of the punch head of the small-opening pressure-blowing glass mould, the surface of the base material of the punch head of the small-opening pressure-blowing glass mould needs to be modified; the existing technology for improving the surface performance of the small-opening pressure-blowing glass die punch is difficult to achieve the expected effect in the aspects of red hardness, thermal fatigue resistance and the like, and a surface welding layer is easy to fracture and fall off, so that the service life of the small-opening pressure-blowing glass die punch is seriously influenced.
The prior art mainly has three types of modification treatment processes for the surface of a small-opening pressure-blowing glass die punch:
(1) The method has the advantages that the flame welding gun is used for manually spraying and welding the nickel alloy powder on the surface of the punch, the method has high requirements on the technical and experience levels of workers, the sprayed and welded layer is uneven in thickness, the sprayed and welded layer is easy to have the spray welding defects such as sand holes, gaps and cracks, the whole sprayed and welded layer can be seriously peeled off, the efficiency is low, and the yield is low;
(2) The plasma spray welding equipment is adopted to carry out the plasma spray welding of nickel alloy powder or cobalt-based alloy powder on the surface of the punch, and the method has the defects that the depth of a molten pool in the plasma spray welding process is not easy to control, the thickness of a spray welding layer is difficult to master, the thickness of the spray welding layer of the punch is uneven, the integral heat dissipation of the punch is uneven, the spray welding layer on the surface of the punch is easy to crack, and the service life of the punch is shortened. Meanwhile, in the plasma spray welding process, a punch to be subjected to spray welding needs to be preheated to a specified temperature at a high temperature before spray welding, and heat preservation and tempering treatment are needed after welding, so that the process is complicated, the energy consumption is high, and the production efficiency is low. In addition, as the spray welding layer of the nickel-based alloy powder has obvious hardness attenuation along with the rise of the temperature of the punch, the requirement of long service life of the punch cannot be met;
(3) The nickel + tungsten carbide alloy powder is sprayed on the surface of the punch at supersonic speed by adopting supersonic speed spraying equipment so as to increase the surface hardness and the thermal fatigue resistance of the punch; the punch treated by the process has good surface red and hard performance and can be used for a long time at the high temperature of 700 ℃. The process has the defects that the welding material is physically combined with the base material, the metallurgical combination effect cannot be achieved, and the sprayed layer is easy to fall off; the supersonic spraying process needs secondary remelting on the spraying part of the punch, is only suitable for spraying nickel-based alloy powder and is not suitable for cobalt-based alloy powder with higher hardness and high-temperature resistance; when the cobalt-based alloy powder is sprayed and coated on the spraying part of the punch for secondary remelting, the situation that the spraying part of the punch is collapsed and scrapped due to the fact that the base metal of the punch is melted before the cobalt-based alloy powder is easily caused due to the high melting point of the cobalt-based alloy powder. The supersonic spraying equipment needs kerosene as fuel, has great noise during working, can generate gases such as carbon monoxide, carbon dioxide, sulfur dioxide and the like during the combustion of the kerosene, and causes environmental pollution by the noise and waste gas.
Therefore, the invention provides a manufacturing process of the small-opening pressure-blown glass mold punch by using laser cladding cobalt-based alloy powder, and the purposes of meeting the stability and long service life of the small-opening pressure-blown glass mold punch in the use environments of high machine speed, high temperature, high pressure and high frequency are achieved.
