Abstract
Disclosed is a special riveting die which comprises an upper die and a lower die. The upper die is combined from an upper die holder and a riveting punch; the upper half part of the riveting punch is imbedded into the upper die holder and is fastened by fixing bolts; a positioning lug boss is arranged on the upper side holder for the convenience of being positioned on a punch bed; the height of the riveting punch is 12cm; the upper half part of the riveting punch is cylindrical and the lower half part takes the shape of a right-angle trapezoid; the section of the lower end of the riveting punch is slightly smaller than the cross section of the shank of a rivet; the lower die is stepped for the convenience of holding a workpiece; a groove is arranged at the upper end face of the lower die to position the head of the positioning rivet; during the riveting process, a bracket is located at the right-angle side of the right-angle trapezoid of the riveting punch and can not ruin the coating at the outer surface of the bracket.
Description
Affiliated technical field
The utility model relates to a kind of riveted particular manufacturing craft used when riveted joint skiving machine support and flight.
Background technology
When skiving machine is installed; need be movably connected skiving machine support and flight by rivet; because the monnolithic case of skiving machine support is irregular, support lacing wire that the boring ratio at the place of driving the rivets closes on and screw rodb base hang down 5cm, arrive the coating of support appearance in the process of riveted through regular meeting's clashing and breaking.
Summary of the invention
The purpose of this utility model is a kind of riveted particular manufacturing craft that designs at above-mentioned situation, and the riveted drift by to have designed side lengthening, Lower Half be the plane adapts to the riveted joint needs, not clashing and breaking skiving machine rack surface when riveted.
The purpose of this utility model is achieved in that a kind of riveted particular manufacturing craft, form by upper die and lower die, patrix is combined by upper bolster and riveted drift, the riveted drift first half embeds in the upper bolster, fastening by hold-down screw, upper bolster is provided with positioning boss, be convenient to be positioned on the press bed, riveted drift height is 12cm, and the first half of riveted drift is a cylindrical shape, Lower Half is at right angles trapezoidal, the following end section of riveted drift is slightly less than the cross section of rivet nail bar, and counterdie is stepped, is convenient to place work piece, the upper surface of counterdie is provided with groove, is used for the ailhead of quilting rivet.
The beneficial effects of the utility model are, riveted drift height is 12cm, and the first half of riveted drift is a cylindrical shape, and Lower Half is at right angles trapezoidal, the following end section of riveted drift is slightly less than the cross section of rivet nail bar, coating that can clashing and breaking support appearance in the riveted process.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, groove; 2, counterdie; 3, upper bolster; 4, riveted drift; 5, hold-down screw; 6, positioning boss.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of riveted particular manufacturing craft as shown in Figure 1, form by upper die and lower die 2, patrix is combined by upper bolster 3 and riveted drift 4, riveted drift 4 first halves embed in the upper bolster 3, fastening by hold-down screw 5, upper bolster 3 is provided with positioning boss 6, be convenient to be positioned on the press bed, riveted drift 4 height are 12cm, the upper end of riveted drift 4 is cylindrical shape, the following end section of riveted drift 4 is slightly less than the cross section of rivet nail bar, therefore riveted drift 4 lower ends are at right angles trapezoidal, counterdie 2 is stepped, the upper surface of counterdie 2 is provided with groove 1, be convenient to place work piece, be used for the ailhead of quilting rivet, directly over riveted drift 4 lower end aligned grooves 1, the utility model is fixed on the press bed, regulates the patrix height, the rivet that passes flight and skiving machine support is put on the counterdie 2, manufactured head is placed in the groove 1, the skiving machine support is positioned at the right-angle side position of the right-angled trapezium of riveted drift 4, and the running of operation press bed drives stroke of patrix running, the nail bar of riveted drift 4 extruding rivets is finished the riveted process.
