The specific embodiment
Need to prove, describe below the word " preceding " that uses, " back ", " left side ", " right side ", " on " and D score refer to direction in the accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of the present invention or its specific features geometric center.
In order to reduce the difficulty of processing in housing bight, save the energy, reduce production costs, do not influence simultaneously the aesthetic measure in housing bight again, four planes that housing corner-shaping method of the present invention will form the bight are changed, and form a new bight bending curved surface R (seeing also Fig. 3, Fig. 4), with the height h reduction of bight punching stretch among Fig. 1, thereby the reduction difficulty of processing reaches goal of the invention.
Specifically, the forming method in housing of the present invention bight is as follows:
Please in conjunction with consulting Fig. 2-3, Fig. 2 shows the bight of a housing, and this bight comprises first side 10, second side 12, first end face 14, second end face 16.The common rib 18 that forms is intersected in first side 10 in this bight, second side 12, wherein the summit of rib 18 is A, end point is B, also has an intermediate point C (intermediate point described here is meant, the arbitrfary point between summit and the end point rather than refer in particular to the summit and the mid point of the end between putting) on the rib.Distance between described summit A and the intermediate point C is H.There is one first incline described first side 10 and first end face, 14 intersections, and there is one second incline described second side 12 and second end face, 16 intersections.
After the height that Fig. 3 shows the housing bight reduces, form two curves respectively, corresponding first curve M on first side 10 and second curve N on second side 12 of being respectively in first side 10, second side 12 of housing.On first end face 14 of housing, second end face 16, also form two curves respectively, corresponding be respectively on first end face 14 the 3rd curve P and, the 4th curve Q on second end face 16.
According to the actual size of housing, guaranteeing under the appearance and modeling prerequisite attractive in appearance that to the position that is displaced downwardly to intermediate point C, the height that is about to rib 18 reduces H to housing corner-shaping method of the present invention with the position of summit, bight A.Thereby the whole height in bight by the summit A among Fig. 1 to the height h of end point B be reduced to intermediate point C among Fig. 4 to the height H of end point B '.
The first, determine the intermediate point C of the rib 18 in housing bight summit A to be reduced to this intermediate point C, promptly determine and the height in bight among Fig. 1 will be reduced H.
Second, on first side 10 of housing, select at one o'clock as first end points, selected another o'clock is as second end points on second side 12 of housing, distance between described first end points and second end points and the rib 18 is respectively the bight and reduces 10-25 highly doubly, be that distance between described first end points and second end points and the rib 18 is respectively 10H-25H, preferably, distance between described first end points and second end points and the rib 18 is respectively the bight and reduces 15-20 highly doubly, and the distance between promptly described first end points and second end points and the rib 18 is respectively 15H-20H.In the actual production process, select the distance of 15H-20H more attractive in appearance, and also be unlikely to have influence on the useful space in housing bight, do not influence the utility function of housing.
The 3rd, described first end points and described intermediate point C form first curve M on described first side 10, and described second end points and described intermediate point C form second curve N (asking for an interview Fig. 3) on described second side 12.
Preferably, described first end points, described second end points and intermediate point C form a new virtual curved face, and first side 10 of virtual curved face that this is new and housing, the intersection of second side 12 are exactly respectively described first curve M and second curve N.It will be understood by those skilled in the art that as preferred implementation the end away from housing rib 18 of first incline of described first end points and described housing is tangent, the end away from housing rib 18 of second incline of described second end points and described housing is tangent.Can reduce the complexity of housing like this, and further reduce difficulty of processing, thereby save production cost.
The 4th, do two virtual planes that intersect vertically respectively by described first end points, described second end points, the intersection of these two virtual planes and housing first end face 14, second end face 16 is exactly respectively described the 3rd curve P and the 4th curve Q (asking for an interview Fig. 2).
The 5th, according to the shape formation housing bight of described first curve M of determining in the above-mentioned steps, second curve N, the 3rd curve P, the 4th curve Q, and make the stretching in bight highly effectively reduce H.Under the prerequisite of the useful space that does not influence the housing bight and utility function, reduce the complexity of housing, and difficulty of processing, thereby saved production cost.
Using housing corner-shaping method of the present invention, can effectively reduce the difficulty of processing in housing bight, simultaneously can also keep the body profile of housing constant substantially, only is that corner shape has obtained fine setting, unlikely housing function, effect is exerted an influence.
It will be understood by those skilled in the art that housing corner-shaping method of the present invention mainly is applicable to metallic stamping pieces, but can also adopt processing methods such as stretching, bending in the actual process.
The foregoing description is only for the usefulness that the present invention is described, and be not to be limitation of the present invention, the those of ordinary skill in relevant technologies field, without departing from the present invention, can also make various variations and modification, therefore, all technical schemes that are equal to also should belong to category disclosed by the invention.
