Bending device for nut plate hemming

Abstract

The invention aims to provide a bending device for a nut plate covered edge. The bending device for the nut plate covered edge can be used for stably and reliably edge-covering a nut plate, and comprises a base for supporting a nut plate assembly, wherein a locking unit for tightly pressing the nut plate assembly and a bending unit for executing an edge-covering bending action are arranged above the base. According to the scheme, the nut plate assembly is firstly placed on the base, then a locking unit acts to lock the position of the nut plate assembly, and then the bending unit acts to bendthe covered edge, so that the whole edge-covering process is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for automobile production, in particular to a bending device for hemming a nut plate. Background technique [0002] The traditional rear door lock hook is installed on the body through a component composed of a nut plate and a nut box, in which the nut box is fixed on the lock hook reinforcement plate through two welding points. As we all know, the smoke and strong magnetic field generated during the spot welding process It has adverse effects on the human body and the environment, and the spatter splashed during welding will also cause harm to the human body and equipment. In order to avoid the above-mentioned defects, the applicant of the present invention submitted a patent application titled "Installation Structure of Locking Hook Nut Plate" on the same day, and directly set flanges on the locking hook reinforcement plate to limit the position of the nut plate. The structure is as ...

[0002] The traditional rear door lock hook is installed on the body through a component composed of a nut plate and a nut box, and the nut box is fixed on the lock hook reinforcement plate through two welding points. As we all know, the smoke and strong magnetic field generated during the spot welding process It has adverse effects on the human body and the environment, and the spatter splashed out during welding will also cause harm to the human body and equipment

In order to avoid the above-mentioned defects, the applicant of the present invention submitted a patent application titled "Installation Structure of Locking Hook Nut Plate" on the same day, and a flanging is directly arranged on the locking hook reinforcement plate to limit the position of the nut plate. The structure is as follows: figure 1 As shown, but because the lock hook reinforcement plate is a curved plate, it is not easy to bend the flange on the middle plate surface of the bottom plate without destroying its original performance
