Abstract
The utility model relates to a die cushion set of a fan main shaft for a large wind turbine. The die cushion set is formed by superimposing at least two die cushions (2) up and down; the center of each die cushion (2) is provided with a center through hole (5) with slope; lower hoisting holes (4) are machined at the outer edge of the upper part of the die cushions (2); lower operating machine clamping grooves (3) are machined at the outer edge of the lower part of the die cushions (2); the upper end face of the die cushion (2) is machined with a concave step (1); and the lower end face of the die cushion (2) is machined with a convex step (2). The die cushion set has the advantages of strong generality, high work efficiency, low labor intensity of workers and low production cost.
Description
(1) technical field
The utility model relates to a kind of large-scale wind driven generator main shaft and forges the moulds of industrial equipment of moulding.Belong to the forging machinery technical field.
(2) background technology
The kind of blower fan main shaft is a lot, but general shape is basic identical, all is the big flange of an end, and an end is the afterbody of step axle shape.Before the utility model is made, forged blower fan main shaft in the past and do not adopt special die-cushion.Therefore its highly versatile is not strong, inefficiency, and working strength of workers is big, the production cost height.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of highly versatile, high efficiency, large-scale wind driven generator blower fan main shaft die-cushion group that production cost is low are provided.
The purpose of this utility model is achieved in that a kind of large-scale wind driven generator blower fan main shaft die-cushion group, described die-cushion group is superposeed up and down by two die-cushions at least and constitutes, each die-cushion center is provided with the central through hole of a band gradient, die-cushion top outer rim is processed with down hole for hoist, die-cushion bottom outer rim is processed with down the manipulator holding tank, the die-cushion upper surface is processed with concave station rank, be used for cooperatively interacting with the boss rank of countersunk head mould lower surface, the die-cushion lower surface is processed with boss rank, is used for cooperatively interacting with the concave station rank of another die-cushion upper surface.
Adopt the utility model processing blower fan main shaft, improved operating efficiency, reduced working strength of workers.
(4) description of drawings
Fig. 1 is the utility model large-scale wind driven generator blower fan main shaft die-cushion group schematic diagram.
Among the figure: concave station rank 1, boss rank 2, following manipulator holding tank 3, following hole for hoist 4, central through hole 5.
(5) specific embodiment
Referring to Fig. 1, the large-scale wind driven generator blower fan main shaft die-cushion group that the utility model relates to, described die-cushion group are superposeed up and down by two die-cushions 2 at least and constitute.Each die-cushion 2 center is provided with the central through hole 5 of a band gradient, die-cushion 2 top outer rims are processed with down hole for hoist 4, die-cushion 2 bottom outer rims are processed with down manipulator holding tank 3, die-cushion 2 upper surfaces are processed with concave station rank 1, be used for matching with the boss rank of countersunk head mould lower surface, die-cushion 2 lower surfaces are processed with boss rank 2, are used for matching with the concave station rank of another die-cushion upper surface.Cooperatively interact fixed with concavo-convex step die-cushion and countersunk head mould and adjacent two die-cushions.
Claims (1)
1, a kind of large-scale wind driven generator blower fan main shaft die-cushion group, it is characterized in that: described die-cushion group is at least by two die-cushions (2) formation that superposes up and down, each die-cushion (2) center is provided with the central through hole (5) of a band gradient, die-cushion (2) top outer rim is processed with down hole for hoist (4), die-cushion (2) bottom outer rim is processed with down manipulator holding tank (3), die-cushion (2) upper surface is processed with concave station rank (1), die-cushion (2) lower surface is processed with boss rank (2), and these boss rank (2) cooperatively interact with the concave station rank of another die-cushion upper surface.
