Abstract
The invention relates to an edge-covering structure which comprises a bottom face. Two adjacent lateral sides of the bottom face are provided with a plate bending face and a plate bending face. One end of the plate bending face is of a right-angle structure. A trapezoid convex block is formed at the position of the right-angle structure. One end of the plate bending face is provided with a concave block matched with the trapezoid convex block. The plate bending faces and covered edges after the plate bending faces are bent are provided with a short vertical connection edge and an inclined connection edge. After the adjacent plate bending faces are bent, the edges are covered, the position of the covered edges is tight, covered-edge marks do not exist, and operational safety of workers is effectively protected. When the edge-covering structure is stacked, a gap is small, and assembly is firm and reliable. After the edge is covered, the intensity of stamping parts is high, integrality is good, deformation is not easily formed, the length of an overlapped edge is shortened, machining time is saved, and cost is reduced.
Description
Technical field
The present invention relates to the bound edge technical field, especially be applicable to the binding structure of industries such as electric bin, electric complete set of equipments and panel beating.
Background technology
In the modern industrial technology, in mechanical automation manufacturing process equipment and the production line, for the corner that makes process equipment simplifies the structure, efficient activity, attractive in appearance and practical, usually use the bound edge technology, by the mode at the corner of equipment employing bending bound edge, thereby avoid adopting welded complex operations in the past.
But be applied to the bending binding structure of switch cubicle corner in the prior art, it locates bound edges and bound edge place, right angle, side respectively, and there are the following problems at 90 ° of angles:
One, as shown in Figure 1, comprise bottom surface 105, described bottom surface 105 adjacent dual-sides are provided with folding surface 101 and folding surface 104, described folding surface 101 and folding surface 104 respectively upwards after the turnover at an angle of 90, bound edge place after described folding surface 101 and folding surface 104 bendings leaves edge sealing 102 and edge sealing 103, and mainly there is following shortcoming in it:
(1) still be all clear tangible bound edge slits of leaving, side from the front, its intensity a little less than, attractive in appearance inadequately; (2) there are tangible edge sealing 102 and edge sealing 103 in the bound edge place, easily scratches the workman in workman's operating process;
Two, as shown in Figure 2, comprise bottom surface 105, described bottom surface 105 adjacent dual-sides are provided with folding surface 101 and folding surface 108, one end of described folding surface 108 structure that meets at right angles, after described folding surface 101 and folding surface 108 upwards turn down respectively, bound edge place after its bending leaves overlap edge 106 and overlap edge 107, and mainly there is following shortcoming in it:
(1) a bottom overlap edge 107 is left in the side that is positioned at switch cubicle, after the cabinet assembly unit finishes, on channel-section steel during move left and right, easily overlap edge 107 is drawn back, when many cabinets body is pieced together cabinet, can leave the slit between cabinet and the cabinet, assembly unit is not tight, and intensity is low, easily collapses;
(2) there are bottom overlap edge 107 and vertically lapped limit 106 in the visible bound edge place, side that is positioned at switch cubicle, and is longer because of overlap edge, makes that the intensity of sheet metal component reduces behind the bending bound edge; Swash when punch press carries out corner cut and dash the distance lengthening, lengthen process time.
Summary of the invention
The applicant exists edge sealing and overlap edge at above-mentioned bound edge technology of the prior art, uses shortcomings such as operation inconvenience, provides a kind of rational in infrastructure, binding structure easy to make, thus eliminated edge sealing and overlap edge, improved intensity, reduced cost.
The technical solution adopted in the present invention is as follows:
A kind of binding structure comprises the bottom surface, and the adjacent side of described bottom surface is provided with plate folding surface and plate folding surface, an end of the described plate folding surface structure that meets at right angles, and described right-angle structure place is protruding fast in echelon; Described plate folding surface one end is provided with and trapezoidal protruding recessed of matching soon; Bound edge after described plate folding surface and the bending of plate folding surface has short perpendicular fillet and oblique fillet.
Its further technical scheme is:
The gap at described plate folding surface and plate folding surface bound edge place is 0.3mm-0.5mm.
Beneficial effect of the present invention is as follows:
The present invention by adjacent plate folding surface bending after bound edge, its bound edge place is tight, no bound edge vestige has effectively been protected workman's processing safety, the slit is less when stacked, assembly unit is solid and reliable; Sheet metal component intensity height behind the bound edge, integrality is good and not yielding; Shortened the length of overlap edge, saved process time, reduced cost.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
When a kind of binding structure of the present invention is applied to the switch cubicle of sheet metal component, as shown in Figure 3 and Figure 4, comprise bottom surface 5, the adjacent edge of bottom surface 5 is provided with plate folding surface 1 and plate folding surface 4, one end of plate folding surface 4 structure that meets at right angles, the right-angle structure place is protruding fast in echelon; Plate folding surface 1 one ends are provided with and trapezoidal protruding recessed of matching soon; There are short perpendicular fillet 2 and oblique fillet 3 in bound edge place after plate folding surface 1 and 4 bendings of plate folding surface; Tiltedly the length of fillet 3 is less than the length of overlap edge in the prior art.
The present invention carries out the mitered bound edge in the side of switch cubicle, is positioned at the front of switch cubicle, without any the bound edge vestige; Be positioned at the perpendicular fillet 2 of weak point and the oblique fillet 3 at the visible bound edge place, side of switch cubicle, the gap at bound edge place is 0.3mm-0.5mm, its bound edge is tight, the edge sealing that occurs in the prior art and overlap edge have been avoided clearly and irrational phenomenon, effectively protected the fail safe of workman's operation, and all fillets all are positioned at the side of switch cubicle, have effectively guaranteed the working strength of switch cubicle; Be positioned at side bottom, become arc structure after the bending, do not have the limit that leaks outside, when switch cubicle is positioned at when moving on the channel-section steel, can protect the complete of sheet metal component, and indeformable; When a plurality of switch cubicles were stacked, assembly unit was tight; Because tiltedly the length of fillet 3 is less than the length of overlap edge in the prior art, when punch press was processed corner cut, it swashed towards distance short, has saved process time.
More than describing is explanation of the invention, is not that institute of the present invention restricted portion within protection scope of the present invention, can be done any type of modification referring to claim to the restriction of invention.
