Description

Technical Field

[0001] The present invention relates to the technical field of wind power flange production, and in particular to an automatic forming device and method for producing offshore wind power flanges. Background Art

[0002] In the production of wind turbine flanges, it is usually necessary to first perform high-temperature extrusion forging on the steel pads, pierce the center, and then form them through a ring rolling machine. However, in the existing production process, forging and forming are two separate processes. During this process, the flanges need to be transported, which reduces the production rate. In addition, there are certain risks during transportation due to the high temperature characteristics of the raw materials. The Chinese patent with application number 2023116713296 discloses a production device and method for a wind turbine main engine pitch flange. The patent places the forging production device directly on one side of the ring rolling device, thereby reducing the overall footprint of the equipment. At the same time, by setting a transfer component, the forged high-temperature workpiece is directly transported to the ring rolling device, which is more convenient without the need for additional transfer. The above-mentioned device places the production device in the ring rolling device in sequence and then transports it through the transfer assembly. Although it solves the safety problem in the transportation process, it has certain requirements and limitations on the spatial layout of the site and the supporting use of the ring rolling machine.

Spraying of coolant is done by starting the first electric telescopic rod, which pushes the support block, the rotating motor, the fixed block and the nozzle to move upward synchronously. At the same time, the industrial camera is used to determine whether the height of the nozzle meets the requirement. When the height is reached, the second electric telescopic rod is started to push the four groups of nozzles to move synchronously. At the same time, the rotating motor and the industrial camera are used to drive the nozzles toward the roller body of the auxiliary roller and the core roller respectively. Then, the coolant in the coolant tank is pumped into the coolant tank through the delivery pipe and the hose and sprayed out by the nozzle.

[0014] The beneficial effects of the present invention are as follows: the present invention achieves an integrated design of forging and ring rolling by installing the forging mechanism and the ring rolling mechanism inside the same outer shell at the same time.
