Embodiment 1

[0043] Embodiment 1: A processing device for rounded corners of pin shafts, used for processing rounded corners of pin shafts, see attached figure 1 , including a workbench 1, a base plate 26 arranged on the workbench 1, a drum 2 arranged on the base plate 26, a vibrating screen 3 arranged at the discharge end of the drum 2, and a vibrating plate 4 arranged below the vibrating screen 3; the drum 2 One end is provided with a material inlet 21, and the other end is provided with a material outlet 22. The vibrating screen 3 is located under one end of the drum 2 outlet 22; the sand and the pin shaft that needs to be rounded are added to the drum 2 together, and the drum 2 During the rolling process, the sand is driven to fillet the pin shaft. After processing, the sand and the pin shaft are added to the vibrating screen 3 together. After being screened by the vibrating screen 3, the pin shaft is sent out from the discharge end of the vibrating screen 3. , the sand is sent out fro...

Embodiment 2

[0051] Embodiment two: a kind of production technology of chain mainly comprises the following steps:

[0052] (1) Chain piece processing: a. Cutting: use a punch to cut the chain piece; b. Vacuum quenching: use propane and kerosene as fuel to heat the chain piece to 850-880°C, and then keep it warm for 45-80 minutes; after the heat preservation, use oil as the medium to quench the chain piece; c. Cleaning and degreasing: use water to clean the chain after quenching, and clean the oil stains on the surface of the chain; d. Tempering: heat the chain to 280-320°C, keep it warm for 30-40 minutes, then take it out and cool it to room temperature with air;

[0053] (2) Roller processing: a. Cutting: using roller chain coiler to produce shaft sleeve; b. Quenching: Use propane and methanol as fuel to heat the roller to 800°C, and then keep it warm for 45 minutes; after the keep warm, use water as the medium to quench the chain piece; c. Tempering: heat the roller to 260°C, then ...

Embodiment 3

[0059] Embodiment three: a kind of production technology of chain, mainly comprises the following steps:

[0060] (1) Chain piece processing: a. Cutting: use a punch to cut the chain piece; b. Vacuum quenching: use propane and kerosene as fuel to heat the chain piece to 860°C, and then keep it warm for 60 minutes; after the heat preservation, use oil as the medium to quench the chain piece; c. Cleaning and degreasing: use water to clean the chain after quenching, and clean the oil stains on the surface of the chain; d. Tempering: heat the chain to 300°C, keep it warm for 35 minutes, then take it out and cool it to room temperature with air;

[0061] (2) Roller processing: a. Cutting: using roller chain coiler to produce shaft sleeve; b. Quenching: Use propane and methanol as fuel to heat the roller to 810°C, and then keep it warm for 45 minutes; after the keep warm, use water as the medium to quench the chain piece; c. Tempering: Heat the roller to 270°C, keep it warm for...
