Technical field
The present invention relates to a kind of connection piece making method, especially a kind of hydraulic turbine generator damping ring connection sheet manufacturer
Method.
Background technique
Currently, hydraulic generator rotor is the important component in hydrogenerator, its structure is that several magnetic poles are uniform
Ground is mounted on the outside diameter hoop of rotor field spider, and each field leads are connected with each other and are combined into rotor.The number of rotor
Connection between a magnetic pole, one therein is exactly rotor when the damping ring of each magnetic pole being interconnected with connection sheet
Magnetic pole forms an entirety.
Wherein, connection sheet is built up by multiple 0.5 millimeter thin copper sheets, is then manufactured using special mold,
Both ends welding is integral after the completion of manufacture, then bores four through-holes in connection sheet with drilling machine again, passes through through-hole and rotor magnetic pole
On damping ring connection.Since the manufacture mold of connection sheet is more complicated, cause the manufacturing cost of connection sheet higher, meanwhile, by
In complicated mould structure, causes connection sheet forming effect also poor, lead to connection sheet unstable quality.
Summary of the invention
It is an object of the invention to provide a kind of low-cost hydraulic generator rotor assembly connection piece making methods.
It is realized the purpose of the present invention is technical solution in this way, a kind of Damper Rings in Synchronous Generator connection sheet manufacture

The lower die of short shutter is placed on hydraulic press lower table face；3) connection sheet blank is placed in the lower die of press-moulding die；4) will
Upper mold is placed on connection sheet blank, is carried out by long baffle and short shutter by gentle snap；5) mobile hydraulic press upper table
To press-moulding die upper mold top surface, hydraulic press upper table is continued traveling downwardly, until the upper mold of press-moulding die suppresses connection sheet blank forming；6)
Milling mould is put into milling machine；7) it will be put at parison in milling mould；8) Milling Process is carried out at the length and width of parison, obtained
To finished product.
Wherein, the press-moulding die includes lower die and upper mold, the lower die upper surface is provided with connection sheet type chamber, described
Upper mold is provided with the connection sheet protrusion with the cooperation of connection sheet type chamber, sets vertically respectively in the side side of the lower die and rear end face
Set the long baffle and short shutter connecting with lower die.
Wherein, the milling mould includes lower mold body and upper die body, and connection sheet placed cavity is provided in the lower mold body,
The lower end surface of the upper die body, which is provided with, holds out against protrusion with what connection sheet placed cavity cooperated；At upper die body upper surface both ends point
It is not provided with the pressing plate with fastening bolt.
By adopting the above-described technical solution, the present invention has the advantages that the processing is simple, easy to use, easy to operate, adopt
Quickly and easily connection sheet can be manufactured with it, not only cost is relatively low, meanwhile, forming effect is good, so that connection sheet matter
Amount is stablized.

Detailed description of the invention of the invention is as follows:
Fig. 1 is press-moulding die structural schematic diagram of the invention；
Fig. 2 is press-moulding die working state structure schematic diagram；
Fig. 3 is milling mode structure schematic diagram of the invention.
Specific embodiment
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing, but the present invention does not limit to
In these embodiments, any improvement or substitution on the present embodiment essence spirit still falls within the claims in the present invention and is wanted
Seek the range of protection.
Embodiment 1: as shown in Figure 1, 2, 3, a kind of Damper Rings in Synchronous Generator connection piece making method, the method includes
Following steps: 1) long baffle and short shutter are installed in the lower die of press-moulding die；2) it will be placed equipped with the lower die of long short slab and short shutter
Onto hydraulic press lower table face；3) connection sheet blank is placed in the lower die of press-moulding die；4) upper mold is placed in connection sheet
On blank, carried out by long baffle and short shutter by gentle snap；5) mobile hydraulic press upper table is to press-moulding die upper mold top surface,
Hydraulic press upper table continues traveling downwardly, until the upper mold of press-moulding die suppresses connection sheet blank forming；6) milling mould is put into milling machine；
7) it will be put at parison in milling mould；8) Milling Process is carried out at the length and width of parison, obtains finished product.
Wherein, the press-moulding die includes lower die 1 and upper mold 2, and 1 upper surface of lower die is provided with connection sheet type chamber 3,
The upper mold 2 is provided with the connection sheet protrusion 4 cooperated with connection sheet type chamber 3, in the side side of the lower die 1 and rear end face point
