Problems solved by technology

However, the position of the door hinge where the nut plate is installed is generally a position with a large bearing force. The existing nut plate has low structural strength and rigidity, and is easily deformed when subjected to a large impact, resulting in the loosening of the hinge.
Moreover, most of the predetermined positions for installing nut plates have relatively narrow space, and it is inconvenient to weld nuts

Abstract

The invention discloses a nut plate mounting device for vehicle door assembly and a punching process, and relates to the technical field of metal punching. The nut plate mounting device realizes separate matching between a nut plate and a mounting plate through forming a first groove and a second groove in the nut plate for connecting with the mounting plate. The mounting plate is not only used for fixing the nut plate to provide convenience to weld a nut, but also reinforces structural strength of the nut plate to bear higher impact external force so as to guarantee reliable connection in a use state and improve the safety coefficient. The nut plate punching process has the characteristics of the nut plate based on the nut plate.

Description

technical field [0001] The invention relates to the technical field of metal stamping, in particular to a nut plate installation device and a stamping process for vehicle door assembly. Background technique [0002] In the manufacture and assembly of automobiles, for door assembly, nut plates are usually welded at predetermined positions to improve the strength of parts installation. However, the position of the door hinge where the nut plate is installed is generally a position with a large bearing force. The existing nut plate has low structural strength and rigidity, and is easily deformed when subjected to a large impact, resulting in the loosening of the hinge. And most of the predetermined positions where the nut plate is installed have relatively narrow spaces, and it is inconvenient to weld the nuts. Contents of the invention [0003] One object of the embodiments of the present invention is to provide a nut plate installation device, which includes a nut plate an...
