Abstract
The utility model provides a generator stator ventilation slot plate that enables ventilation channel steel to be accurately positioned. The generator stator ventilation slot plate comprises a ventilation slot plate body and ventilation channel steel fixed on a right surface of the ventilation slot plate body. The right surface of the ventilation slot plate body is provided with a positioning device that is used for positioning the ventilation channel steel.
Description
Technical field
The utility model relates to generator stator ventilation slot board and processes the mould of this ventilation channel plate.
Background technology
Along with the high speed development of China's economic, power consumption increases very fast, and the market demand of large and medium generator is very large.We know that generator power is larger, and the diameter of stator core is wider, length is longer.And more want strict for the control of iron core temperature, thereby the air-conditioning requirement of iron core has been improved relatively.Because stator core mainly ventilates by the stator ventilation channel plate, so the quality of stator ventilation channel plate is directly connected to the quality of product.
Generator stator ventilation slot board referring to Fig. 1,2, comprises ventilation channel plate body 1 and the ventilation steel channel 2 that is welded on the ventilation channel plate body front.The point welding process of existing stator ventilation channel plate operates with operating personnel's technology and experience fully, the not accurate enough problem of calibration of some ventilation steel channels often can occur.This affects concerning small generation set may be little, but impact will be very large for the large and medium generator group, because its stator ventilation channel plate area is very large, depends merely on operating personnel's technology and experience spot welding difficulty is large, is difficult to reach the product quality requirement.
In addition, when electricity generator stator core laminated, the accuracy of ventilation steel channel distributing position on the stator ventilation channel plate was extremely important, and the mode that laminates of stator ventilation channel plate is that rotation is put, and the position of every one deck channel-section steel must be consistency from top to bottom.When compressing iron core, every channel-section steel is bearing same pressure, and is evenly distributed like this, is conducive to iron core be compressed and be unlikely to produce the phenomenon of collapsing, thereby has guaranteed product quality.If the stator ventilation channel plate is out of joint, just serious quality accident might occur.
Summary of the invention
The position that the purpose of this utility model provides a kind of ventilation steel channel is generator stator ventilation slot board accurately.
This generator stator ventilation slot board comprises ventilation channel plate body and the ventilation steel channel that is fixed on the ventilation channel plate body front, is provided with for the positioner to the ventilation steel channel location in ventilation channel plate body front.
The beneficial effects of the utility model: by positioner ventilation steel channel is positioned, eliminated the mode of existing artificial range estimation, accurate positioning has guaranteed that the position that ventilation steel channel is welded on the ventilation channel plate is accurate.
Above-mentioned generator stator ventilation slot board, described positioner comprise two pairs of projections that are arranged on the ventilation channel plate body front, and every pair of projection is positioned at the ventilation steel channel both sides, and two pairs of projections lay respectively at the both ends of close ventilation steel channel.By this simple structure of projection, can reach locating effect.Described projection is that the ventilation channel plate body is carried out punching press and forms recess at the back side of ventilation channel plate, forms projection in the front of ventilation channel plate; The bottom of ventilation channel plate body has groove.
The utility model provides the mould of the above-mentioned generator stator ventilation slot board of a kind of processing of the positional precision that can guarantee projection simultaneously.
The mould of processing generator stator ventilation slot board of the present utility model comprises upper die and lower die, and counterdie embeds supporting bracket, is provided with by the location-plate of two finger settings on supporting bracket in supporting bracket, and the width of location-plate is less than or equal to the width of groove.
The beneficial effect of this mould: during use, processed ventilation channel plate is placed on the supporting bracket, and the location is stretched in the groove, with contacting of bottom surface ventilation channel plate is positioned with the side of groove by location-plate.Then by the punching press of patrix, can punching out go out described projection.Be arranged on position on the patrix by changing location-plate, can the different projection of punching out.
Above-mentioned mould, location-plate have two, and a width equates that with recess width a width is less than recess width.

Embodiment
Referring to the generator stator ventilation slot board shown in Fig. 3,4, comprise ventilation channel plate body 1 and the ventilation steel channel 2 that is welded on the ventilation channel plate body front, be provided with for two pairs of projections 3 to the ventilation steel channel location in ventilation channel plate body front, every pair of projection is positioned at the ventilation steel channel both sides, and two pairs of projections lay respectively at the both ends of close ventilation steel channel.Described projection is that the ventilation channel plate body is carried out punching press and forms recess at the back side of ventilation channel plate, forms projection in the front of ventilation channel plate; The bottom of ventilation channel plate body has groove 4.
Referring to Fig. 5,6, the mould of the projection of processing on the generator stator ventilation slot board comprises patrix 5 and counterdie 10, and counterdie 10 embeds supporting brackets 6, is provided with by two pins, 7 location and by bolt 8 in supporting bracket and is fixed on location-plate 9 on the supporting bracket.Location-plate has two, and referring to Fig. 7, location-plate 91 width equate that with recess width another piece location-plate 92 width are less than recess width.
Accurate for the position that can make each root channel-section steel, we must guarantee with mould its position.
On the stator ventilation channel plate, the distribution of ventilation steel channel has certain angle to require, and has three kinds of fixing position C, D, E(and sees Fig. 7), be not equally distributed.Therefore we adopt the method for adjusting locating piece to come substep punching out projection when designing mould.The projection that the location-plate 91 that width is identical with groove is used for rushing position D, E, width is used for the projection of punching out position C less than the location-plate 92 of groove.
Arrange in supporting bracket and to divide locating piece two position F, G fixing two groups of pin-and-holes 11 that cooperate with pin 7, locating piece 91 is fixed on F place, position, locating piece 91 contacts with the bottom surface with two sides of groove, can be on ventilation channel plate the projection of punching out position E; Locating piece 91 is fixed on G place, position, and locating piece 91 contacts with the bottom surface with two sides of groove, can be on ventilation channel plate the projection at D place, punching out position; Locating piece 92 is fixed on F place, position, and locating piece 91 contacts with the bottom surface with a side of groove, can be on ventilation channel plate the projection at C place, punching out position.As long as the locator protrusions of different angles just can be gone out in the position of adjustment locating piece to be come, very easy to use, quick when production and processing.
Come punching out to put the ventilation steel channel locator protrusions at the stator ventilation channel plate, like this when spot welding as long as ventilation steel channel is placed between the projection, just had good positioning naturally in the position.Make point welding process become simple and practical, alleviated operating personnel's labour intensity, improved the crudy of workpiece, reduced the damage rate of part, improved the stability of product quality.
