Abstract
The invention discloses a matching structure of a clamp and a groove at the edge of a chassis, which can guarantee the rigidity of the edge of a chassis front plate and also guarantee the matching effect of the chassis front plate and the clamp on a plastic panel. The matching structure comprises a chassis front plate, a recess and a technical hole, wherein the chassis front plate is formed by bending, the recess is arranged on one side of the edge on the chassis front plate, and the technical hole is arranged in the recess. The processing method of the matching comprises the following steps of: a, punching a technical hole on a chassis front plate in a forming recess on one side of a bending line; b, stamping the chassis front plate above the technical hole to form an upper half part of the recess; and c, bending the chassis front plate and stamping to form a lower half part of the recess. The invention is suitable for the location of stamping the recess on the chassis front plate.
Description
Technical field
The present invention relates to structure and the job operation thereof of a kind of cabinet seamed edge place grab fit.
Background technology
Computer housing is a vitals in computer, in order to reduce production costs, the most frequently used fit system in case fore-plate place is: as Fig. 1, Fig. 2, shown in Figure 3, grab 3 is set on plastic front board 2, one groove 5 is set on case fore-plate 1, thereby plastic front board 2 is fixed on case fore-plate 1 by the side that grab 3 catches on groove 5.The job operation of the groove 5 on above-mentioned case fore-plate 1 is: a. is at case fore-plate 1 upper punch fabrication hole 4, and this fabrication hole 4 is positioned on the seamed edge that is about to be shaped; B. as shown in Figure 2, the case fore-plate 1 of fabrication hole 4 tops is carried out punching press, form groove 5; C. case fore-plate 1 is carried out bending.Final structure such as Fig. 1, Fig. 2, shown in Figure 3 that forms.As shown in Figure 1, because the case fore-plate seamed edge of groove 5 one sides is cut, greatly affected case fore-plate 1 rigidity at this place (in Fig. 1 and Fig. 3 A place), cause case fore-plate 1 easily to be out of shape, be difficult to guarantee the stable of dimension D in Fig. 3, dimension D be on case fore-plate 1 with plastic front board 2 on the fit dimension of grab, finally cause coordinating the generation gap between plastic front board 2 and case fore-plate 1, become flexible thereby produce, affect fiting effect.
Summary of the invention
Technical matters to be solved by this invention is: will provide a kind of and can guarantee case fore-plate seamed edge place rigidity, and can guarantee again the structure of cabinet seamed edge place grab fit of the fiting effect of grab on case fore-plate and plastic front board simultaneously.
Another technical matters to be solved by this invention is: will provide a kind of and can guarantee case fore-plate seamed edge place rigidity, and can guarantee again the job operation of structure of cabinet seamed edge place grab fit of the fiting effect of grab on case fore-plate and plastic front board simultaneously.
For addressing the above problem, the technical solution used in the present invention is: the structure of cabinet seamed edge place grab fit, comprise the case fore-plate that forms by bending, be arranged on the groove of seamed edge one side on case fore-plate, it is characterized in that: also comprise the fabrication hole that is arranged in groove.
The job operation of the structure of a kind of cabinet seamed edge place grab fit the steps include: a. at case fore-plate upper punch fabrication hole, and this fabrication hole is arranged in the groove that will be shaped of bending line one side; B. the case fore-plate above fabrication hole is carried out punching press, form the first half of groove; C. case fore-plate is carried out bending, and the latter half of drawing groove.
The invention has the beneficial effects as follows: at the middle part of the groove that will be shaped subpunch fabrication hole, can guarantee the stable of the dimension D that coordinates with grab, can guarantee again the rigidity at case fore-plate seamed edge place.

Embodiment
Below in conjunction with accompanying drawing, the job operation of cabinet seamed edge of the present invention place grab fit is described in further detail.
Fig. 4, Fig. 5 and Fig. 6 show the structure of the case fore-plate groove of the job operation drawing that utilizes cabinet seamed edge of the present invention place grab fit, this structure comprises: the case fore-plate 1 that forms by bending, be arranged on the groove 5 of seamed edge 6 one sides on case fore-plate 1, offer fabrication hole 4 in groove 5, one side not the overlapping with bending line of this fabrication hole 4.The step of said structure job operation is: a. is subpunch fabrication hole 4 on case fore-plate, and this fabrication hole 4 is arranged in the groove that will be shaped 5 of bending line one side; The first half that is conducive to like this groove 5 is shaped, and has guaranteed size d; B. punching press is carried out in the case fore-plate 1 of fabrication hole 4 tops, form the first half of groove 5; C. case fore-plate 1 is carried out bending, the latter half of forming pockets 5 has simultaneously guaranteed the rigidity of case fore-plate 1 upper groove 5 one lateral edges 6.Because bending is once completed by mould with the Lower Half of forming pockets 5, cause the material of this bending part to be extruded, stretch, make size k meeting unstable, but after having had fabrication hole 4 as buffering, just can not affect the fit dimension D with plastic front board, be that dimension D remains stable, so just can well guarantee between case fore-plate and plastic front board coordinate stable.
Claims (1)
1. the job operation of the structure of cabinet seamed edge place grab fit, the structure of cabinet seamed edge place grab fit, comprise the case fore-plate that forms by bending, be arranged on the groove of seamed edge one side on case fore-plate and also comprise the fabrication hole that is arranged in groove, its procedure of processing is:
A. at case fore-plate upper punch fabrication hole, this fabrication hole is arranged in the groove that will be shaped of bending line one side, when carrying out back bending and punching press, utilizes this fabrication hole as buffering like this, can guarantee the rigidity intensity at cabinet seamed edge place;
B. the case fore-plate above fabrication hole is carried out punching press, form the first half of groove;
C. case fore-plate is carried out bending, and the latter half of drawing groove.
