Abstract

The invention relates to a single point incremental forming hot air heating working table and a using method thereof, and belongs to the technical field of novel metal material processing. The singlepoint incremental forming hot air heating working table includes a base plate, wherein a supporting tube is arranged on the base plate, a supporting plate extending outwards is arranged on the circumferential part of the upper end of the supporting tube, a fixing plate provided with a mounting through opening is arranged on the supporting plate, a side edge air-out frame plate mounted on the supporting plate and used for supporting blank materials is arranged in the mounting through opening, a material pressing mechanism matched with the side air-out frame plate for pressing the blank materials is arranged on the upper side of the side air-out frame plate, a heating cavity is formed in the supporting tube, the lower part of the heating cavity is connected with a vent pipe, the vent pipe isinternally provided with a heating system and connected with a temperature control system, and a heat insulation structure is further arranged in the supporting tube. According to the single point incremental forming hot air heating system working table, cold air is blown in through an air blower, the air is heated by an electric resistance wire, heat exchange of panel veneers and the hot air isachieved, and the forming limit and forming precision in the process of forming are improved.

Description

technical field [0001] The invention relates to a single-point progressive forming hot air heating workbench and a using method thereof, belonging to the technical field of new metal material processing. Background technique [0002] Incremental forming is a forming and manufacturing technology of layered manufacturing, which discretizes the complex 3D digital model into a series of 2D contour layers along the height direction, and then generates the machining trajectory of the tool head. Under the control of the numerical control system, the tool head performs progressive plastic processing on the sheet according to the NC code of the pre-processed parts. After forming the required cross-sectional profile of the first layer, the tool head moves down by the set incremental step, and then presses the second layer The trajectory of the section profile moves, and this is repeated until the entire part is formed. Dieless incremental forming, that is, dieless layered forming of ...
