Abstract
The utility model discloses a self-punching rivet for riveting plastic metal board, belonging to the mechanical processing field The utility model comprises a rivet cap and a rivet lever; the improvement is that the rivet lever is of a pipe shape provided with an axial hole; the diameter of the axial hole of front of the rivet lever is enlarged gradually to form a segment of taper surface. The riveting procedure is that a rivet is arranged at a selected position; a guide concave mould for the front wall of the rivet is arranged on the outer surface of a bottom metal board corresponding to the position of the rivet; the self-punching rivet is pressed into the metal board with a punch power source; through the guide of the concave mould, the front end of the rivet lever is radially split to form a fork horn shape for locking materials to be riveted. The utility model has the advantages that the punching work of power source and the splitting work of concave mould can be finished once without drilling holes on the metal board. The utility model has the advantages of quick riveting, high efficiency, low power consumption and low noise. The utility model has outstanding use value to products (such as covering parts on a car) with riveting positions at the edge of overlapping boards and with convenient concave mould positioning ability.
Description
Technical field
This practicality newly belongs to the Machining Technology field, is specifically related to rivet the rivet of plastic metal sheet material.
Background technique
The rivet of the contour plastic metal sheet material of existing riveted joint aluminium sheet, need sheet metal to be riveted be punched in advance during use, then rivet is passed the hole of sheet metal to be riveted, difference according to riveting process, make the outer radially extensional of part of rivet hole by the mode of drawing or pressing, reach the purpose that connects sheet metal.Utilize aforementioned rivet to carry out the sheet material riveted joint and connect, the manufacturing process more complicated, manufacturing efficiency is low.
Summary of the invention
The purpose of this utility model provides a kind of self-pierce riveting nail of riveting plastic metal sheet material, realizes not the rivet self-piercing riveting of boring in advance, overcomes prior art by the shortcoming on the formed riveting process of rivet arrangement.
Self-pierce riveting nail of the present utility model comprises the head of a nail, nail bar, and the improvement of being done is that the nail bar partly is that the tubular of axle center hole arranged, and the axle center hole aperture of nail bar front end increases gradually and forms one section conical surface.
Use riveted joint process of the present utility model to be: with flanging equipment sheet metal to be riveted to be compressed earlier, rivet is placed select location, the corresponding rivet of outer surface position at the parent metal plate is equipped with rivet front end tube wall guiding die, with impacting power source the self-pierce riveting nail is pressed into sheet metal afterwards, after rivet bar pierces through the plastic metal sheet material of surface layer, under the leading role of die, nail bar front end is radially rived in parent metal sheet material, form the horn mouth shape, locking riveted joint material, thus reach the purpose that connects sheet metal.
The beneficial effects of the utility model are, use self-pierce riveting nail riveted joint plastic metal plate, need not to hole on sheet metal, and power source nail hitting and die are split nail and once finished.Not only can effectively connect plastic metal sheet material, and have that riveting process is easy, quick, efficient is high, energy consumption is low, pollution-free, low noise advantages.At overlapping sheet edge, can make the product (as the covering on the automobile) of die location for a large amount of riveted joints position more conveniently, outstanding use value is arranged.
Description of drawings
Fig. 1 is the utility model rivet arrangement figure.
Fig. 2 is for using rivet process component of the present utility model and Riveting Tool combination relation figure.
Fig. 3 is the utility model rivet technological effect figure.
Embodiment
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
No. 35 steel that choosing can be heat-treated are with the craftwork manufacture of the precision forging rivet 1 that comprises countersunk head head of a nail 1-1, nail bar 1-2 as shown in Figure 1.The nail bar is tubular that axle center hole 1-3 is arranged, and the axle center hole aperture of nail bar front end increases gradually and forms one section conical surface 1-4.
Self-piercing riveting technology as shown in Figure 2,2 pairs of plastic metal sheet materials to be riveted of pressed edge ring compress, and flow in die under the active force of rivet to prevent material, place rivet 1 in the pressed edge ring.The rivet top is a drift 3, and die 5 is installed below parent metal plate 4.Drift 3 moves downward, and promotes rivet 1 and pierces through upper strata sheet metal 6 to be riveted downwards.Radially rive in parent metal plate 4 at rivet afterbody under the acting in conjunction of die and drift, form the horn mouth shape so that locking riveted joint material reaches the riveted joint purpose.
Effect after the self-pierce riveting nail riveted joint as shown in Figure 3, wherein sequence number 1 is a rivet, sequence number 4 is parent metal plates, sequence number 6 is upper strata sheet metals.
