Preferably, blank drawing die in step (2) is arranged on 40T punch press, punching notch die in punching shaving die in step (3), step (6) and the flanging die in step (7) are arranged on 25T punch press respectively, and shock wave mould in step (4) and the secondary shock wave mould in step (5) are arranged on 16T punch press respectively.
Compared with prior art, the production technology of improved square basin frame of the present invention is used impact style moulding basin frame, thereby has reduced defective products, has reduced production cost; At the blue white zine of basin frame plating trivalent chromium on surfaces, can make the more attractive in appearance and long service life of basin frame profile; By two step punch formings of three Dan Huafen, can avoid the situation of basin frame distortion one time punching molded and that cause to produce; After the single flower of punching and breach, basin frame is carried out to flange, can make convenient location when the single flower of punching and breach.
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 improved square basin frame of the present invention, and this technique comprises that step is as follows:
(1) utilize the material that shearing machine is 0.7mm by the thickness for the manufacture of basin frame to carry out sawing sheet, form the square flitch of 108mm * 108mm.
(2) the square flitch stretching h=16.5mm forming after utilizing blank drawing die to sawing sheet carries out blank simultaneously, and forming opening diameter d1 is that 71.8mm, bottom inner diameter d 2 are the basin body blank of 54.8mm.
(3) utilize punching shaving die to cut out square frame at the edge of basin body blank, in the bottom of basin body blank, go out diameter d 3 for the mesopore 11 of 30mm simultaneously, and on square frame on the circumference of distance center of circle 46.5mm and to go out respectively a length in four corners of square frame be 7.6mm, width is the first oblate installing hole 12 of 4.6mm, the first installing hole 13 that a diameter going out four corners that are distributed in square frame on square frame on the circumference of distance center of circle 46mm is 4mm, the second installing hole 14 and a length that two diameters are 5mm are 6.5mm, width is the second oblate installing hole 15 of 5mm.
(4) using two the second installing holes 14 as locating hole, and utilize a shock wave mould on the sidewall of basin body blank, to go out one and singly spend 16, this singly spends the spacing L1 at 16 two ends is 45.4mm, apart from the bottom 2.6mm of basin body blank, apart from basin body blank top width, is 1.7mm.
(5) using this singly spend 16 as location, and utilize secondary shock wave mould on the sidewall of basin body blank, to go out with this and singly spend 16 another two of being positioned at equal height singly to spend 16, these three singly spend 16 be uniformly distributed and adjacent two singly to spend the spacing L2 between 16 be 22mm.
