Tool setting device and method for double-head counter-pressure progressive forming

Abstract

The invention relates to a double-end pressing-aligning incremental forming tool setting device and method. The double-end pressing-aligning incremental forming tool setting device comprises a gauge base, a main pressing head side tool handle (1), an auxiliary pressing head side tool handle (2), an auxiliary pressing head (3), a reference block (7) and four dial gauge heads, wherein the gauge base comprises a reference hole (4), a gauge support (5) and a clamping column (6), the clamping column (6) is located at the tail end of the gauge base and clamped at the tail end of the main pressing head side tool handle (1), the gauge support (5) is fixedly arranged on the clamping column (6), the mean axis of the reference hole (4) of the gauge base is overlapped with the mean axis of the main pressing head side tool handle (1) when the gauge base is installed, the four dial gauge heads are arranged on the gauge support (5) in an every-two opposite mode, the auxiliary pressing head (3) is arranged on the auxiliary pressing head side tool handle (2), the auxiliary pressing head is aligned to the reference hole (4), and the reference block (7) is matched with the reference hole (4). Compared with the prior art, the double-end pressing-aligning incremental forming tool setting device and method solves the problem that coaxial tool setting of pressing heads is difficult to achieve in double-end pressing-aligning incremental forming.

Description

technical field [0001] The invention relates to a device in the technical field of sheet metal progressive forming. In particular, it relates to a tool setting device and method for double-head counter-pressure progressive forming. Background technique [0002] Sheet metal incremental forming is a sheet metal forming technology that has emerged in recent years. It has the characteristics of flexible forming methods, good forming performance and flexibility, and is especially suitable for the production and processing of single-piece and small-batch metal sheet products. At present, there are still some problems in incremental forming, such as poor surface quality of parts, long forming time of single piece and poor geometric accuracy. Among them, the reason for the poor geometric accuracy of the parts is mainly due to the bending effect, springback and pillow effect of the sheet during the incremental forming process. In order to improve the geometric precision of parts, m...
