Technical field
The present invention relates to a kind of production technology of the basin frame with concave station, relate in particular to a kind of production technology that has reduced the basin frame with concave station of production cost.
Background technology
Basin frame is for the fixing support of loudspeaker, generally adopts steel or aluminium to be made.Common basin frame, conventionally by casting, also needs after casting conventionally through polishing, and surface roughness is reduced.Although operation is simple, the basin frame defective products of casting is many.
Summary of the invention
The production technology that the object of this invention is to provide a kind of basin frame with concave station, the basin frame of production is attractive in appearance and defective products is few, has reduced production cost.
For achieving the above object, the invention provides a kind of production technology of the basin frame with concave station, this processing step comprises:
(1) utilize the material that shearing machine is 0.5mm by the thickness for the manufacture of basin frame to carry out sawing sheet, form the square flitch of 112mm * 112mm;
(2) the square flitch forming after utilizing Blanking mould to sawing sheet carries out Blanking, forms diameter and is followed successively by from top to bottom 76mm, 66mm, 41mm, the basin body blank that the degree of depth is 14mm;
(3) utilize punching shaving die to carry out trimming at the edge of basin body blank, formation has the basin body of circular frame, in the bottom of basin body blank, go out the mesopore that diameter is 19mm simultaneously, on the circumference of the distance from bottom center of circle of basin body blank 13mm, go out the rivet hole that four equally distributed diameters are 3.1mm, and on the circumference of distance center of circle 44mm, go out the installing hole that four equally distributed diameters are 5mm on circular frame;
(4) utilize the bottom that raising platform punching die is 41mm at basin body diameter to get the degree of depth for 5mm, lower diameter is the boss of 35mm, simultaneously on the sidewall of basin body, going out two centre-to-centre spacing is the earhole that 20mm, diameter are 2mm, and the square opening of going out a long and wide 3.1mm of being on the sidewall of basin body and in the centre of two earholes;
(5) utilization is returned limit mould the circular frame of basin body is returned to limit, and the basin body outside diameter returning behind limit is 98.5mm, and each position of mounting hole place indentation platform on circular frame, forms basin frame product simultaneously;
(6)) to basin frame product spray black powder S1B.
Preferably, Blanking mould in described step (2) is arranged on 40T punch press, and the raising platform punching die in the punching shaving die in step (3), step (4) and the limit mould that returns in step (5) are arranged on 25T punch press respectively.
Compared with prior art, the production technology of the basin frame with concave station of the present invention is used impact style moulding basin frame, thereby has reduced defective products, has reduced production cost; At basin frame surface spraying black powder, can make basin frame profile more attractive in appearance; Return limit and indentation platform completes a step, raising platform, rush earhole and square opening completes a step, reduced processing step, reduce production costs; By indentation platform step, can make the basin frame intensity that can also increase basin frame of cutting more attractive in appearance after moulding.
By following description also by reference to the accompanying drawings, it is more clear that the present invention will become, and these accompanying drawings are used for explaining embodiments of the invention.
Accompanying drawing explanation
Fig. 1 is the production technological process of basin frame of the present invention.
Fig. 2 is the schematic diagram of basin frame of the present invention.
Fig. 3 is the cutaway view of Fig. 2.
The specific embodiment
With reference now to accompanying drawing, describe embodiments of the invention, in accompanying drawing, similarly element numbers represents similar element.
Please refer to Fig. 1-3, is the specific embodiment of the production technology of the basin frame of band concave station of the present invention, and this technique comprises that step is as follows:
(1) utilize the material that shearing machine is 0.5mm by the thickness for the manufacture of basin frame to carry out sawing sheet, form the square flitch of 112mm * 112mm.
(2) the square flitch forming after utilizing Blanking mould to sawing sheet carries out Blanking, forms diameter d 1, d2, d3 are followed successively by 76mm, 66mm, 41mm, the basin body blank that degree of depth h1 is 14mm from top to bottom.
(3) utilize punching shaving die to carry out trimming at the edge of basin body blank, formation has the basin body 1 of circular frame, in the bottom of basin body blank, go out the mesopore 11 that diameter is 19mm simultaneously, on the circumference of the distance from bottom center of circle of basin body blank 13mm, go out the rivet hole 10 that four equally distributed diameters are 3.1mm, and on the circumference of distance center of circle 44mm, go out the installing hole 12 that four equally distributed diameters are 5mm on circular frame.
(4) utilize the bottom that raising platform punching die is 41mm at basin body diameter to get degree of depth h2 for 5mm, the boss 2 that lower diameter d 4 is 35mm, simultaneously on the sidewall of basin body, going out two centre-to-centre spacing L is the earhole 13 that 20mm, diameter are 2mm, and the square opening 14 of going out a long and wide 3.1mm of being on the sidewall of basin body and in the centre of two earholes.
(5) utilization is returned limit mould the circular frame of basin body 1 is returned to limit, and the basin body 1 outside diameter d5 returning behind limit is 98.5mm, and each installing hole 12 positions indentation platforms 15 on circular frame, form basin frame product simultaneously.
(6)) to basin frame product spray black powder S1B.
Further illustrate, the Blanking mould in step (2) is arranged on 40T punch press.Raising platform punching die in punching shaving die in step (3), step (4) and the limit mould that returns in step (5) are arranged on 25T punch press respectively.
In sum, owing to using impact style moulding basin frame, thereby reduce defective products, reduced production cost; At basin frame surface spraying black powder, can make basin frame profile more attractive in appearance; Return limit and indentation platform completes a step, raising platform, rush earhole and square opening completes a step, reduced processing step, reduce production costs; By indentation platform step, can make the basin frame intensity that can also increase basin frame of cutting more attractive in appearance after moulding.
