Existing riveting techniques are not suitable for thin sheets. Because the thin plate does not have enough thickness to compress in its forward direction, the insufficient deformation in the forward direction causes enough deformation in the plane direction to insert the rivet, so the rivet cannot be firmly fixed to the thin plate.
A rivet is a nail-shaped object used to connect two parts (or members) with a through hole and a cap on one end. In riveting, the riveted parts are connected by their own deformation or interference. There are many types of rivets, and they are informal.
The embedded nut proposed by Guangdong Yueluo Hardware Industry Co., Ltd. is used to be embedded in an injection molded part. The embedded nut is arranged in a column shape and has a screw hole inside. The embedded nut includes an outer peripheral surface and is formed in the inner nut. The upper end surface and the lower end surface of the two ends of the embedded nut are provided with knurling on the outer peripheral surface, and a guide surface is formed at the connection between the outer peripheral surface and the lower end surface.
Self-tapping screws, or quick-thread screws, are quick-release fasteners made of steel that are galvanized and passivated on the surface. Self-tapping screws are mostly used for the connection between thin metal plates (steel plates, saw plates, etc.). When connecting, first make a threaded bottom hole for the connected piece, and then screw the self-tapping screw into the threaded bottom hole of the connected piece.
Generally, the T-bolt structure is common, and its blank shape can be completed at one time on a multi-station cold heading machine. But for T-bolts with relatively rare structures, (for example: the intersection of ¢14x42 cylinder (head) + ¢12 cylinder, the two cylinders form a 90° intersection) due to the special structure, the head Cold forming is difficult, and the traditional processing route is: die casting blank → deburring → turning processing → grinding blank diameter → wire rolling → heat treatment → surface treatment → finished product packaging.
