A combined multi-point die shape adjustment device for sheet metal

Abstract

The invention relates to a combined sheet multi-point die shape-adjusting device. The combined sheet multi-point die shape-adjusting device comprises a basic body and adjusting device thereof, an inner side guard plate, an outer side guard plate, a supporting base plate and a magnet. The basic body and adjusting device thereof, the inner side guard plate and the outer side guard plate are arranged on the supporting base plate; the magnet arranged at the bottom of the supporting base plate provides electromagnetic adsorption force to fix the basic body and adjusting device thereof, the inner side guard plate and the outer side guard plate on the supporting base plate; the basic body and adjusting device thereof comprises basic bodies, fixing screws and bases; the basic bodies are connected with the bases through the fixing screws, and the height of the basic bodies is adjusted through the fixing screws; and the inner side guard plate and the outer side guard plate are assembled with the basic bodies in a matched manner to prevent the basic body and adjusting device thereof from inclining or bending caused by side direction force. Compared with the prior art, the combined sheet multi-point die shape-adjusting device has the advantages of simple structure, short development period, reduced production cost, flexibility, adjustability and the like.

Description

technical field [0001] The invention relates to a sheet material flexible forming die, in particular to a multi-point die for sheet material three-dimensional curved surface forming. Background technique [0002] Multi-point die forming is a hot technology in the field of three-dimensional surface forming of sheet metal. Its principle is to discretize the traditional die surface and use a series of regularly arranged, height-adjustable primitives to describe the geometric characteristics of the parts to be formed. The "flexible multi-point mold" composed of basic bodies replaces the traditional integral mold for stamping, which greatly reduces the time cost and manufacturing cost caused by the design, development and manufacture of stamping molds, and can well meet the needs of many industrial products in today's market. Requirements in terms of aspects, such as high degree of personalization, fast replacement, and change of production batches from large batches to medium an...
