How Many Steps Can Crankshaft Processing Be Divided Into?

The small curved shaft of the blank is forged, and the large crankshaft is cast with nodular cast iron. When forging, the bar material is red and threaded into multiple forging molds, forging into a multi curved planar shape. In the red heat state, the next process turns each bend to a suitable angle.

Locate the parking space, locate the center of the main journal on an ordinary lathe, and locate both ends of the parking space.

Main journal.

The vehicle connecting rod journal is a tool carriage that follows the rotation of the connecting rod journal on a special vehicle while simultaneously feeding the cutter, and simultaneously feeding two connecting rod journals with the same angle into the vehicle at one time; (For trial production or non batch production, an eccentric jig is made on a common lathe chuck, with the connecting rod journal as the rotation center.).

Drill oil passage holes. There is a lubricating oil passage inside the crankshaft from the main journal to the crank arm to the connecting rod journal. Use special equipment to drill deep holes.

High frequency quenching quenches the main shaft and connecting rod journals to improve surface hardness.

Grind the neck of the spindle.

The connecting rod neck is polished by a very precise dedicated crank grinder, which automatically measures and grinds the connecting rod neck. The accuracy is controlled by 0.01.

Other processing, flywheel connecting keyways, oil return grooves, screws, etc.

Balancing and weight removal are also special equipment that can be used to remove weight from the detected overweight boom reserve using a drill bit. The above production processes are all automatically controlled by the equipment, and the operators are only assisting with loading and unloading. Migrant workers are very good. The level is reflected in the manufacturing, commissioning, and maintenance of these equipment. After observation, it was found that no matter what kind of parts with different shapes were, they could be produced efficiently. Special equipment (a certain process that processes only one type of part) or flexible CNC equipment (adjustable in size to accommodate multi-part production).
