Problems solved by technology
[0003] Aiming at the problems existing in the prior art, the invention provides a device and method for sheet metal forming, which solves the technical problem that the three-dimensional milling template is scrapped and newly produced due to the change of the local shape of the part. The device has a simple structure and low manufacturing cost. Inexpensive, easy to operate By adjusting the screw mechanism in the device, riveted sheet metal with different curvatures can be formed, and then the curvature of the riveted sheet metal is consistent with the curvature of the riveted part of the three-dimensional milling template, so as to achieve the purpose of changing the shape of the three-dimensional milling template Purpose

The invention discloses a device for sheet metal forming, which has a support frame, a backing plate is provided on the support frame, several stroke adjustment bolts are arranged on the backing plate, and several connecting plates are arranged on the top of the backing plate. There is a threaded hole in the middle that matches the stroke adjustment bolt, and the connecting plate is sleeved on the stroke adjustment bolt through the threaded hole. The connecting plate is located on both sides of the stroke adjustment bolt and is symmetrically provided with a slider linkage mechanism; the slider linkage The mechanism includes a linkage rod and a slider arranged on the linkage rod. One end of the linkage rod is connected to the connecting plate through a nut, and the slider is arranged on the other end of the linkage rod. One end of the slider is provided with two lugs arranged up and down. Ⅰ and Ⅱ, the lug Ⅰ is provided with fastening bolts, and the lug Ⅱ is provided with supporting studs. The device has a simple structure, and can form riveted sheet metals with different curvatures, so that the curvature of the riveted sheet metals is consistent with the curvature of the riveted part of the three-dimensional milling template, so as to achieve the purpose of changing the shape of the three-dimensional milling template.
Description
technical field [0001] The invention belongs to the field of sheet metal forming, and specifically relates to a device and method for sheet metal forming. Background technique [0002] In the process of aircraft design, maneuverability is an important indicator. In order to make the aircraft have better maneuverability, the weight of parts needs to be strictly controlled under the premise of meeting the strength requirements. Since there are many aircraft skin parts, the weight of the aircraft can be effectively reduced by reducing its local thickness. The internal milling area of such skin parts is usually processed by chemical milling (referred to as "chemical milling"), and chemical milling is now mainly using chemical milling templates for scoring of the protective adhesive layer before chemical milling. For the three-dimensional milling parts, it is necessary to process the three-dimensional milling template. If the increase in the shape of the part is greater than 1...
