Abstract

The invention discloses a floating supporting single-point incremental hot forming device. The floating supporting single-point incremental hot forming device comprises a supporting body device, the supporting body device comprises a bottom plate, a lower sliding plate and an upper sliding plate, at least two guide columns are fixedly installed on the bottom plate, the upper sliding plate and thelower sliding plate are installed on the guide columns in a sliding mode; a heating clamping device used for clamping a to-be-machined plate is fixedly installed on the upper sliding plate, a floatingheating supporting mold device which penetrates through the upper sliding plate and the lower sliding plate and extends into the heating clamping device to make contact with the to-be-machined plateis fixedly installed on the bottom plate; heating parts electrically connected with a controller are arranged at the contact position of the heating clamping device and the to-be-machined plate and the contact position of the floating heating supporting mold device and the to-be-machined plate; and adjusting devices used for adjusting the floating force of the floating heating supporting mold device are fixedly arranged on the bottom plate and the lower sliding plate.

Description

technical field [0001] The invention relates to the technical field of metal material processing, in particular to a floating support single-point incremental thermoforming device. Background technique [0002] The single-point incremental forming technology of sheet metal is based on the idea of ​​layered manufacturing, which makes three-dimensional thin-walled parts two-dimensional, and uses the compiled numerical control code to control the machine tool to drive the forming tool head to move along the processing track. Pressure is applied to plastically deform the material, and finally the desired shape of the part is obtained. The principle is as figure 1 shown, figure 1 The middle serial number 1 is the sheet to be processed, 2 is the blank holder, and 3 is the tool. [0003] When processing thin-walled parts with flat bottom features such as cylinders, square boxes, truncated cones and square truncated cones, when the parts are formed by the single-point incremental...
