Abstract
The utility model relates to the technical field of hardware processing, in particular to a riveted structure of a screw and a plate. The riveted structure comprises a screw, a plate, an upper die and a lower die; a riveting hole matching with the screw is arranged on the plate; at least two stages of press-in components are arranged at a screw cap end of the screw; the outer diameter of a stage of the press-in component positioned at the outermost end is larger than the outer diameters of the other stages of the press-in components; a chamfer of the stage of the press-in component positioned at the outermost end is a right angle; the screw is inserted into the riveting hole of the plate; each stage of the press-in component of the screw is pressed into the plate; the upper die is arranged on the upper surface of the plate; the lower die is arranged on the lower surface of the plate; a thread end of the screw is inserted into a hole of the lower die; and the press-in component with right-angle structure at the outermost end of the screw is perpendicularly pressed into the plate to decrease deformation of materials and pressure riveting marks. As the pressure riveting marks are decreased, only simple baking top coat is needed to cover the pressure riveting marks, and the riveted structure simplifies processing technology, saves resources and meets the requirements of saving energy and protecting environment.
Description
Technical field:
The utility model relates to the five metals processing technique field, relates in particular to screw and sheet material riveted structure.
Background technology:
As shown in Figure 1, at present, when screw 101 is riveted with sheet material 102, because the portion that is pressed into 103 of screw 101 is R corner structures, when screw 101 is pressed into sheet material 102, can produce and draw the material phenomenon, can produce the darker seal that presses (in shown in the A) on sheet material 101 surface, even also can't hide the above-mentioned seal that presses by spraying as Fig. 1, influence surface quality of products, be difficult to satisfy requirement of client.In order to solve the problem of the above-mentioned seal that presses, at present, mostly adopt benefit to fill out technology and hide the seal that presses, technology is as follows: press, surface treatment, manually wire drawing, mend fill out, polish, roasting finish paint, this processing technology complexity, cost height, the quality instability, and this technological process is not energy-conservation, not environmental protection, causes the wasting of resources.
The utility model content:
The purpose of this utility model is to provide screw and sheet material riveted structure at the deficiencies in the prior art, and it reduces the seal that presses of plate surface by increasing the portion that is pressed at one-level right angle, has overcome the deficiencies in the prior art.
For achieving the above object, the utility model is achieved through the following technical solutions:
Screw and sheet material riveted structure, comprise screw, sheet material, upper die and lower die, described sheet material is provided with the riveted holes with described screw coupling, the nut end of described screw is provided with at least, and two-stage is pressed into portion, the external diameter that the one-level that is in outermost end is pressed into portion is pressed into the external diameter of portion greater than other grade, and the chamfering that the one-level of outermost end is pressed into portion is the right angle; Described screw inserts in the riveted holes of described sheet material, and the portions of being pressed at different levels of described screw all are pressed into described sheet material, and described patrix is arranged on described sheet material upper surface, described counterdie is arranged on described sheet material lower surface, and the end of thread of described screw inserts in the hole of described counterdie by sheet material.
The nut end of described screw is provided with two-stage and is pressed into portion.
Described counterdie is provided with annular boss with the surface that contacts of described sheet material.
The external diameter of described annular boss is pressed into the external diameter of portion greater than the one-level of described screw outermost end, and the internal diameter that encircles described annular boss is pressed into the external diameter of portion less than the one-level of described screw outermost end.
The beneficial effects of the utility model: the mode that is pressed into that screw adopts two-stage to go forward one by one at least, simultaneously, the portion of being pressed into of outermost end is designed to right-angle structure, the portion of being pressed into of outermost end vertically is pressed into sheet material, can reduce distortion of materials, and seal reduces to press; Print because press and to reduce, only need simple roasting finish paint can hide the seal that presses, simplified processing process economizes on resources, and reaches the requirement of energy-saving and environmental protection.
Description of drawings:
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is a bolt structure schematic diagram of the present utility model;
Fig. 3 is the upward view of Fig. 2;
Fig. 4 is the structural representation of the utility model riveted joint.
In Fig. 1 to Fig. 4:
Screw 101, sheet material 102, be pressed into portion 103;
Screw 1, be pressed into portion 11,12;
Sheet material 2, patrix 3, counterdie 4.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
See Fig. 2 to Fig. 4, screw and sheet material riveted structure, comprise screw 1, sheet material 2, patrix 3 and counterdie 4, described sheet material 2 is provided with the riveted holes with described screw 1 coupling, the nut end of described screw 1 is provided with two-stage and is pressed into portion 11,12, the external diameter that the first order that is in outermost end is pressed into portion 11 is pressed into the external diameter of portion 12 greater than the second level, and the chamfering that the first order of outermost end is pressed into portion 11 is the right angle; In the riveted holes of the described sheet material 2 of described screw 1 vertical insertion, and, first, second level of described screw 1 is pressed into portion 11,12 and all is pressed into described sheet material 2, described patrix 3 is arranged on described sheet material 2 upper surfaces, and screw 1 applied downward pressure, described counterdie 4 is arranged on described sheet material 2 lower surfaces, and the end of thread of described screw 1 inserts in the hole of described counterdie 4 by sheet material.
See Fig. 4, described counterdie 4 is provided with annular boss 41 with the surface that contacts of described sheet material 2, the external diameter of described annular boss 41 is pressed into the external diameter of portion 11 greater than the first order of described screw 1 outermost end, and the internal diameter of described annular boss 41 is pressed into the external diameter of portion 11 less than the first order of described screw 1 outermost end.In the present embodiment, suppose that the external diameter that the first order is pressed into portion 11 is the K value, then the external diameter of annular boss 41 is K+0.6, and internal diameter is K-0.8, and this structure can satisfy the roof pressure requirement.
See Fig. 4, during riveted joint, in the riveted holes of the described sheet material 2 of screw 1 vertical insertion, the nut end of patrix 3 extrusion screws 1, the downside of counterdie 4 roof pressure sheet materials 2, the R angle of screw 1 produce when being pressed into portion 12 and being pressed into and draw material, and the distortion of formation then is pressed into portion 11 by the first order of right-angle structure and vertically is pressed into sheet material 2 and reduces, the edge right-angle structure that is pressed into portion 11 is just as cutting knife, vertical incision effectively reduces and draws material, promptly reduces the seal that presses, it is less at the impression that sheet material 2 surfaces form to be pressed into the back, can hide by roasting finish paint.During the downside of counterdie 4 roof pressure sheet materials 2, its annular boss 41 can reduce depression by roof pressure power established material recess, reaches the smooth more smooth purpose of material surface.
