Abstract
The utility model relates to a composite mould for a main shaft of a fan, and the composite mould is used for fabricating a main shaft of a large-scale wind driven generator in a forging penetration manner. The mould comprises an upper die (1) and a lower die (2). An upper cavity (1.2) with an inclination is arranged in the center of the upper die (1); the upper edge of the upper cavity (1.2) is fabricated to have a great arc (1.1); a hoisting hole (1.5) is fabricated on the outer edge of the upper part of the upper die (1); an upper manipulator holding groove (1.4) is formed on the outer edge of the lower part of the upper die (1); a convex step (1.3) is fabricated on the lower end surface of the upper die (1); a lower cavity (1.2) with an inclination is formed in the center of the lower die (2); a lower hoisting hole (2.4) is fabricated on the outer edge of the upper part of the lower die (2); a lower manipulator holding groove (2.3) is fabricated on the outer edge of the lower part of the lower die (2); and a convex step (2.1) is fabricated on the upper end surface of the lower die (2) and matched and fixed with the convex step (1.3) on the upper die. The composite mould has the advantages of strong universality, high working efficiency, low labor intensity of workers, and low fabricating 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, as shown in Figure 1.Before the utility model was made, blower fan main shaft was in the past only used a mold moulding.Its versatility is not strong, and the blower fan main shaft of different-diameter and length needs to come moulding with different moulds.So its inefficiency, 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, blower fan main shaft composite die that production cost is low are provided.
The purpose of this utility model is achieved in that a kind of blower fan main shaft composite die, by upper die and lower die two parts, described patrix center is provided with the upper impression of a band gradient, the upper impression upper limb is arranged to orthodrome, patrix top outer rim is processed with hole for hoist, patrix bottom outer rim is processed with the manipulator holding tank, and the patrix lower surface is processed with boss rank; Described counterdie center is provided with the lower impressions of a band gradient, counterdie top outer rim is processed with down hole for hoist, counterdie bottom outer rim is processed with down the manipulator holding tank, the counterdie upper surface is processed with concave station rank, match with the boss rank of described patrix in these concave station rank, with upper die and lower die with the fixation that cooperatively interacts of concavo-convex step.
By this cover composite die, can be effectively that the blower fan main shaft flange head is carried out local pier is thick, and make it to forge saturating, thereby guaranteed forging quality, improved operating efficiency, reduced working strength of workers.The versatility that this cover composite die is done blower fan main shaft is more intense, and 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.Flange is the jumping-up moulding, and the material that calculates flange end when the diameter of flange can lean on ejection is heavy just can be controlled; The size control of afterbody weight pattern tool die cavity only increases and decreases the blower fan axle tail shape that cushion block just can pull out different-diameter and length in the counterdie die cavity.Therefore, the much the same blower fan main shaft of specification type can be produced with this mold.
On the other hand, this mould can also use separately, patrix can forge the short and small flange forging that axle head has flange, counterdie can forge to push away and pull out forging, gradient can directly forge moulding, and upper and lower mould makes up malleable fan engine main shaft, and versatility is extremely strong, demonstrate fully its flexibility, also lowered die cost.
(4) description of drawings
The blower fan main shaft forging drawing that Fig. 1 relates to for the utility model.
Fig. 2 is the patrix figure of the utility model blower fan main shaft composite die.
Fig. 3 is the counterdie figure of the utility model blower fan main shaft composite die.
Fig. 4 is the utility model blower fan main shaft composite die general structure schematic diagram.
Among the figure: patrix 1, counterdie 2, blower fan main shaft 3, blower fan main shaft forging 4; Orthodrome 1.1, upper impression 1.2, boss rank 1.3, last manipulator holding tank 1.4, last hole for hoist 1.5; Concave station rank 2.1, lower impressions 2.2, following manipulator holding tank 2.3, following hole for hoist 2.4, flange head 4.1, neck 4.2, afterbody 4.3.
(5) specific embodiment
Referring to Fig. 2～4, the blower fan main shaft composite die that the utility model relates to is made up of patrix 1 and counterdie 2 two parts.Described patrix 1 center is provided with the upper impression 1.2 of a band gradient, upper impression 1.2 upper limbs are arranged to orthodrome 1.1, patrix 1 top outer rim is processed with hole for hoist 1.5, and patrix 1 bottom outer rim is processed with manipulator holding tank 1.4, and patrix 1 lower surface is processed with boss rank 1.3; Described counterdie 2 centers are provided with the lower impressions 2.2 of a band gradient, counterdie 2 top outer rims are processed with down hole for hoist 2.4, counterdie 2 bottom outer rims are processed with down manipulator holding tank 2.3, counterdie 2 upper surfaces are processed with concave station rank 2.1, matching with the boss rank 1.3 of described patrix in these concave station rank 2.1, cooperatively interacts fixed with concavo-convex step patrix 1 and counterdie 2.
The blower fan main shaft forging process is as follows:
First fire: steel ingot saw material is after heating, and winching to the press planker, to carry out whole pier thick, pulls out anistree back number seal and advances stove and continue heating.
Second fire: the blank of holding successfully sling insert the composite die that combines by upper and lower mould, the thick flange of local pier, will carry out repeatedly rotation to forging in the thick process of pier, pier hangs out mould after dimensional requirement, and the folder small end vertically is placed on flange head on the anvil piece, carry out the thick flange head of pier, it is big that drafts is wanted, and to guarantee the quenching degree of forging flange end, enters mould once more behind the round as a ball again flange head, the pier flange head melts down after the size of upsetting.
The 3rd fire: pulling afterbody step is to size, smooth flange head.
