Opening-and-closing type heater and wind generator shaft forging process using the same

A wind generator shaft forging process, using an opening-and-closing type heater, the opening-and-closing type heater comprising a base, a tube body mounted on the base and a tube body opening-and-closing mechanism;

• the tube body comprising a fixed tube body and a movable tube body, the fixed tube body and the movable tube body being arc-shaped shells and openings thereof forming a hollow shape and defining two opposite open ends of the tube body when matched with each other;
• the tube body opening-and-closing mechanism being connected to the movable tube body for realizing the opening-and-closing of the movable tube body and the fixed tube body;
• wherein a refractory fireproof material layer is arranged on an inner wall of the fixed tube body and the movable tube body, wherein the wind generator shaft forging process comprises:
• placing the opening-and-closing type heater on a worktable of a forging press, and keeping an opening-and-closing center of the opening-and-closing type heater on a same axis of a wind generator shaft forging;
• and starting the heater to heat the wind generator shaft forging when it is necessary to heat the wind generator shaft forging.

• the tube body opening-and-closing mechanism being connected to the movable tube body for realizing the opening-and-closing of the movable tube body and the fixed tube body;
• wherein the heater further comprises a heater moving mechanism that moves the opening-and-closing type heater in a direction perpendicular to an opening-and-closing centerline of the opening-and-closing type heater, and the base thereof is mounted on the heater moving mechanism, wherein the wind generator shaft forging process comprises:
• arranging the opening-and-closing type heater with the heater moving mechanism on one side of a wind generator shaft forging between a clamping head for clamping the wind generator shaft forging on a forging manipulator and an anvil of a forging press;
• when it is necessary to heat the wind generator shaft forging, sending the opening-and-closing type heater to a center of the wind generator shaft forging by the heater moving mechanism and starting the heater to heat the wind generator shaft forging.
