Embodiment 1
[0028] A processing technology for improving the service life of a pin shaft, comprising the following steps:
[0029] (1) Quenching treatment:
[0030] Put the pin into the quenching furnace for quenching treatment, take it out after 45 minutes, and then immerse it in the quenching liquid for 1 hour of cooling treatment and take it out for use;
[0031] (2) Tempering treatment:
[0032] Put the pins treated in step (1) into a tempering furnace for tempering treatment, take them out after 1.5 hours, and then naturally cool to room temperature for later use;
[0033] (3) Surface spraying treatment:
[0034] The prefabricated composite material is sprayed on the surface of the pin shaft treated in step (2) by a spray gun, and then placed in an incubator for heat preservation for 2 hours and then taken out.
[0035] During the quenching treatment described in step (1), the temperature in the quenching furnace is controlled to be 820°C.
[0036] The quenching liquid described ...
Embodiment 2
[0049] A processing technology for improving the service life of a pin shaft, comprising the following steps:
[0050] (1) Quenching treatment:
[0051] Put the pin into the quenching furnace for quenching treatment, take it out after 48 minutes, and then immerse it in the quenching liquid for 1.3 hours of cooling treatment and take it out for use;
[0052] (2) Tempering treatment:
[0053] Put the pins treated in step (1) into the tempering furnace for tempering treatment, take them out after 1.8 hours, and then naturally cool to room temperature for later use;
[0054] (3) Surface spraying treatment:
[0055] The prefabricated composite material is sprayed on the surface of the pin shaft treated in step (2) by a spray gun, and then placed in a thermostat for 2.5 hours of heat preservation and then taken out.
[0056] During the quenching treatment described in step (1), the temperature in the quenching furnace is controlled to be 840°C.
[0057] The quenching liquid desc...
Embodiment 3
[0070] A processing technology for improving the service life of a pin shaft, comprising the following steps:
[0071] (1) Quenching treatment:
[0072] Put the pin into the quenching furnace for quenching treatment, take it out after 50 minutes, then immerse it in the quenching liquid for cooling treatment for 1.5 hours and take it out for use;
[0073] (2) Tempering treatment:
[0074] Put the pins treated in step (1) into the tempering furnace for tempering treatment, take them out after 2 hours, and then naturally cool to room temperature for later use;
[0075] (3) Surface spraying treatment:
[0076] The prefabricated composite material is sprayed on the surface of the pin shaft treated in step (2) by a spray gun, and then placed in a constant temperature box for heat preservation for 3 hours and then taken out.
[0077] During the quenching treatment described in step (1), the temperature in the quenching furnace is controlled to be 850°C.
