Double-sided multi-point incremental forming device

Abstract

The invention relates to the field of punching and plastic processing technologies for plates, and provides a double-sided multi-point incremental forming device which comprises two side pressing tables, an upper punch and at least three lower punches. Fastening assemblies are arranged on the two side pressing tables and are used for fixing a sheet to be formed, the two side pressing tables are used for fastening a plane of the sheet at the same altitude, the upper punch is arranged above the sheet to be formed and is connected to a first mechanical arm, and the first mechanical arm is controlled by a control unit; the lower punches are arranged below the sheet to be formed, are fixed onto a lower punch fixing seat and are arrayed to form a polygon, the lower punch fixing seat is connected to a second mechanical arm, the second mechanical arm is controlled by the control unit, and the upper punch and the lower punches are perpendicular to the sheet to be formed. The double-sided multi-point incremental forming device has the advantages of reasonable integral structure, simplicity in operation and utilization, reliable work, compact structure, good modularization, high machining flexibility and capability of meeting incremental forming requirements of different shapes.

Description

technical field [0001] The invention relates to the technical field of sheet metal stamping plastic processing, in particular to a double-sided multi-point incremental forming device. Background technique [0002] At present, precision plastic forming technology has become one of the key research and development directions in the field of manufacturing and processing, mainly including metal precision die forging, precision blanking, extrusion and other processing technologies. The mechanical components through precision plastic forming have precise shape, high dimensional accuracy, high shape and position accuracy, and good surface quality. However, special molds are generally required, and the overall loading is required, which consumes a lot of energy. Special-purpose molds are expensive and have a long development cycle. They are not suitable for the production of large-size and small-batch parts. Discretizing the traditional overall mold into a shape-variable "flexible ...

AI Technical Summary

Problems solved by technology

[0005] However, there is a problem with the above incremental forming equipment: the forming has limitations, the deformation method is single, the processing flexibility is low, and the local support rigidity is insufficient during the forming process of large-scale components, which is not suitable for the forming of complex and changeable large thin-walled parts.
