Embodiment Construction

[0020] The specific embodiment is described in detail below in conjunction with accompanying drawing: as shown in accompanying drawing 3 and 4.

[0021] A method for forging and rolling the flange of a wind power generation tower, the steps include: heating the forged and formed flange blank with a disc portion and a neck to 1200-1250° C. in a heating furnace, and keeping it for 40-50 minutes, It is released from the furnace by the charging machine; then the ring rolling machine is used to expand the diameter and roll, and the ring rolling machine is used to use the double small rib mould, and the billet is finely rolled.

[0022] The double small rib mold includes main roll 1, core roll 2, and main roll 1. The structure includes lower rib 3, main mold 4, tire mold 5, and middle rib 6. On the ring rolling machine, the lower rib 3 of main roll 1 , the main mold 4, the tire mold 5, the middle rib 6 and the rib ring 8 of the core roller 2 form an L-shaped closed shaping path, and...

Abstract

The present invention relates to ring part forging and rolling formation technology, and is especially forging and rolling process of forming flange for wind motor tower. The forging and rolling process includes the following steps: heating the forged flange blank with a disc and a neck in a heating furnace to 1200-1250 deg.c, maintaining for 40-50 min and discharging with one discharging machine; rolling in a ring rolling machine; and finish rolling in the ring rolling machine with double retaining rib molds. Compared with available technology, the present invention has the advantages of saving in material, low power consumption and low production cost.

Description

technical field [0001] The invention relates to a forging and rolling forming process technology of a ring part, in particular to a forging and rolling forming method for a wind power generation tower tube flange. Background technique [0002] Large ring parts are widely used in petroleum, chemical industry, metallurgy and other industries. At present, the manufacturing and forming technology of large ring parts mainly adopts free forging to form cakes, punching, horse frame reaming, rolling and rolling, and then mechanical Processing is finally formed. [0003] Horse frame reaming is to put the blank on the mandrel, hammer the blank on a hydraulic press or an anvil with a forging hammer, and produce elongation along the circumferential direction, so that the wall thickness of the forging is reduced, and the inner and outer diameters are increased at the same time, so as to meet the diameter size requirements. . The disadvantages are that the diameter is too large, the wal...
