A forward incremental forming round hole flanging device

Abstract

The invention relates to a forward incremental forming type round hole flanging device. The forming device comprises a power output part (1), a transmission part (2), a chuck body (3), a thread ring (4) and a forming part (5). One end of the transmission part (2) is connected with the power output part (1), and the other end of the transmission part (2) is connected with the chuck body (3). The transmission part (2) comprises a coupler (21) and a connecting rod (22). The power output part (1) drives the connecting rod (22) through the coupler (21). The connecting rod (22) is fixed to the upper end of the chuck body (3). The chuck body (3) is a rotary body, and an annular groove (31) is formed in the surface of the outer side of the lower portion of the rotary body. A plurality of oblique ducts (32) are formed in the chuck body (3). The extension directions of the multiple oblique ducts (32) intersect with one another on one point of the axis of the chuck body. The oblique ducts (32) penetrate through the annular groove (31). According to the forward incremental forming type round hole flanging device, operation is easy, convenient and rapid, using is flexible, and the application range is wide.

Description

technical field [0001] The invention relates to a forming device for round hole flanging. Background technique [0002] Sheet metal numerical control incremental forming technology is a flexible processing technology that uses pre-programmed control programs to form sheet metal parts point by point by means of digital control equipment and the idea of ​​"layered manufacturing". This process does not require special molds, has good repeatability, can control metal flow, and can process complex-shaped free-form surfaces. It is suitable for small-batch, multi-variety, complex-shaped sheet metal parts processing in aerospace and automotive industries. [0003] Hole flanging is a sheet metal forming technique widely used in the automotive, aerospace and aviation industries. The traditional round hole flanging method is a stamping method in which a round hole is pre-processed on the sheet, and the material around the hole is bent to form a raised flange under the action of the pu...

AI Technical Summary

Problems solved by technology

[0004] Using CNC machine tools to perform round hole flanging through incremental forming technology can greatly simplify the forming process, but in the forming process, it is necessary to use modeling software to shape and generate tool paths, and to import the paths into CNC machine tools for processing, and for complex 3D parts Difficult to fix to a general workbench

The requirements for equipment and target parts are relatively high, the actual processing process is not flexible enough, and it is not suitable for rapid prototyping of small batch parts, which restricts the wide application of progressive forming round hole flanging process to a certain extent
