The invention provides a shape adjusting device of a reconfigurable mould, comprising a shape adjusting mould, wherein the shape adjusting mould is mounted on an X-Y axis linking platform; the X-Y axis linking platform is mounted on a shape adjusting mounting plate; the shape adjusting mounting plate is mounted above a screw rod mounting plate; screw rods are fixed on the screw rod mounting plate; the screw rods are in self-locking threaded connection with more than two plunger chips; the adjacent plunger chips limit the respective rotation; the positions of the screw rods, close to the connection position of the screw rod and the punch chips, are provided with displacement sensors; the X-Y axis linking platform, the shape adjusting mould and the displacement sensors are connected with a control cabinet through a circuit; the translational motion in a Z direction is realized through gear transmission and screw rod and nut transmission, so that the clutching with the appointed plunger chip is realized; and the four plunger chips are subjected to shape adjustment at the same time by the shape adjusting mould through a fixed shaft gear system, so that a shape surface of the reconfigurable mould is more rapidly adjusted. According to the invention, the shape adjusting time of the reconfigurable mould is shortened, the shape adjusting precision is improved, the cost of molding equipment of the reconfigurable mould is reduced, and the automatic shape adjusting is realized.
Description
technical field [0001] The invention belongs to the technical field of plate forming, and in particular relates to a shape adjusting device of a reconfigurable mold. Background technique [0002] The reconfigurable mold adopts the idea of "discretization", that is, the traditional overall mold is discretized into small punches arranged in a matrix, and the user can quickly adjust the relative position of the punches through manual or computer automatic control to form any desired shape. The required three-dimensional surface is used to manufacture the target part. The emergence of reconfigurable molds not only provides convenience for the flexible design and processing of three-dimensional curved panels, but also reduces the cost of mold development and improves the efficiency of mold development. Combined with the characteristics of reconfigurable molds, it has been widely used in sheet metal processing in the fields of ships, aerospace, automobile manufacturing, constru...
