(2) flitch forming after utilizing Blanking mould to sawing sheet carries out Blanking, and formation outside diameter is that 108mm, upper opening diameter are that 70.7mm, lower diameter are 56.2mm, the taper basin body blank that the degree of depth is 15 ± 0.2mm;
(3) utilize punching shaving die to rush in basin body blank bottom the mesopore that diameter is 24 ± 0.3mm, and on the circumference of basin body blank distance from bottom center of circle 17mm, go out the rivet hole that four equally distributed diameters are 4.2 ± 0.1mm simultaneously, and at basin body blank, on the circumference apart from center of circle 41mm, go out the installing hole that four equally distributed diameters are 4mm, cut out circular frame simultaneously, form the basin body with circular frame;
(4) utilize flanging die to carry out flange to the circular frame of basin body, after flange, the outside diameter of basin body is 89 ± 0.2mm, and interior circular diameter is 75.9 ± 0.1mm;
(5) utilize the basin bottom of raising platform mould after flange to carry out raising platform, formation upper diameter is that 49mm, lower diameter are the cone boss that 43.5mm, the degree of depth are 6.3mm;
(6) utilize and rush the square earhole that earhole mould is gone out long and the wide 3.1mm of being on the sidewall of basin body, form basin frame product;
(7) the basin frame spray black powder S1B liquidating after earhole.
Preferably, Blanking mould in described step (2) is arranged on 40T punch press, in punching shaving die in step (3) and (4), flanging die is arranged on 25T punch press respectively, and the earhole mould that rushes in the raising platform mould in step (5) and step (6) is arranged on 16T punch press respectively.
Compared with prior art, the production technology of circular flange basin frame of the present invention is used impact style moulding basin frame, thereby has improved the precision of basin frame, has reduced production cost; At basin frame surface spraying black powder, can make basin frame profile more attractive in appearance; After being placed on to flange and punching trimming step, raising platform step can avoid the shape that guarantees boss to avoid its distortion.
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 circular flange basin of the present invention frame, and this technique comprises that step is as follows:
(1) utilize shearing machine that the thick material of the 0.4mm for the manufacture of basin frame is carried out to sawing sheet, form the flitch of 112mm * 112mm.
(2) flitch forming after utilizing Blanking mould to sawing sheet carries out Blanking, and formation outside diameter is 108mm, upper opening diameter d 1 for 70.7mm, lower diameter d 2 are 56.2mm, the taper basin body blank that degree of depth h1 is 15 ± 0.2mm.
(3) utilize punching shaving die to rush in basin body blank bottom the mesopore 11 that diameter d 3 is 24 ± 0.3mm, and on the circumference of basin body blank distance from bottom center of circle 17mm, go out the rivet hole 12 that four equally distributed diameter d 4 are 4.2 ± 0.1mm simultaneously, and on the circumference of basin body blank apart from center of circle 41mm, go out the installing hole 13 that four equally distributed diameters are 4mm, cut out circular frame simultaneously, form the basin body 1 with circular frame.
(4) utilize flanging die to carry out flange to the circular frame of basin body 1, after flange, the outside diameter d5 of basin body 1 is 89 ± 0.2mm, and inner circle diameter d 6 is 75.9 ± 0.1mm.
(5) utilize basin body 1 bottom of raising platform mould after flange to carry out raising platform, forming upper diameter d7 is the cone boss 2 that 49mm, lower diameter d 8 are 6.3mm for 43.5mm, degree of depth h2.
(6) utilize and rush the square earhole 14 that earhole mould is gone out long and the wide 3.1mm of being on the sidewall of basin body 1, form basin frame product.
