Problems solved by technology

[0007] Traditional stamping mold processing has problems such as high cost, low efficiency, non-reconfigurable mold, waste of mold materials, etc.
Generally, the structure of reconfigurable mold is complex, the single-point control unit is bulky, and the unit contact point with the plate is small. The indentation of the plate after stamping is large, which will cause wrinkles and deformation. The residual stress inside the plate is large, which will cause the formed parts to deform slowly. question

Abstract

The invention discloses a reconfigurable die. The reconfigurable die comprises a plurality of closely arranged hydraulic telescopic units and a hydraulic system connected with the hydraulic telescopic units, wherein each hydraulic telescopic unit comprises a pressure maintaining cylinder, a telescopic unit hydraulic valve, a hydraulic cylinder and a pressure head; the hydraulic system comprises an oil inlet line, a pressure maintaining oil line and a regulating valve used for switching between the oil inlet line and the pressure maintaining oil line. The invention also discloses a forming device for the reconfigurable die. A die point control mechanism is used for performing point control over the hydraulic telescopic units in the configurable die to form required curved surfaces. The reconfigurable die is low in cost and high in efficiency; through the closely arranged hydraulic telescopic units, unit contact points of the reconfigurable die and parts are increased, the smoothness of the curved surfaces formed by the reconfigurable die is improved, folds and indentation of punched parts can be reduced, internal residual stress of plates after punching is reduced, and the reconfigurable die is favorable for industrial popularization and application.

Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to a reconfigurable mold and a molding device for the reconfigurable mold. Background technique [0002] At present, the main method of manufacturing curved sheet metal parts is stamping forming, but stamping forming requires one or several sets of molds for each part, while traditional stamping mold processing has the disadvantages of high cost, low efficiency and non-reconfigurable, which wastes mold materials , especially when processing parts with small batches, complex shapes, low curvature, and large sizes, the shortcomings of traditional non-reconfigurable molds are particularly prominent. [0003] For this reason, people have proposed a reconfigurable multi-point mold forming technology. The existing representative technical documents include: document 1, a plate multi-point forming device with a patent application number of 02273508.9, and a document 2, a square indent...
