Problems solved by technology

[0002] The material of the centralized compliance mechanism is mainly cut and formed metal sheet. The centralized compliance mechanism is small in size and thickness, and its deformation is a regular spatial deformation. The length of the deformation section is concentrated between 1mm and 2mm. The processing of the mold cannot accurately deform the preset area of ​​​​the metal sheet

Abstract

The invention discloses a plane composite structure space compliant hinge stamping die, which includes a moving sub-bending module and a rotating sub-bending module, and a through hole is formed on the No. 1 bending block of the moving sub-bending module for the No. 1 clamping assembly Passing through, the movement trajectory of the No. 1 clamping component is limited, which prevents the deviation of the No. 1 clamping component during the bending process and leads to processing failure; in addition, the turning pair bending module includes the No. 2 clamping component, the vertical For the straight press block and a pair of horizontal press blocks, the No. 2 clamping assembly is provided with a limit structure that limits the moving track of the horizontal press block, and a short-side bending part is provided for the lower end of the vertical press block to pass through. The movement trajectory of the vertical pressing block is limited during the working process, which ensures that the two can accurately act on the preset deformation area of ​​the metal sheet, which greatly improves the processing yield.

Description

technical field [0001] The invention relates to the technical field of sheet metal forming, in particular to a stamping die for a space-compliant hinge of a plane composite structure. Background technique [0002] The material of the centralized compliance mechanism is mainly cut and formed metal sheet. The centralized compliance mechanism is small in size and thickness, and its deformation is a regular spatial deformation. The length of the deformation section is concentrated between 1mm and 2mm. Machining by the mold simply cannot deform the sheet metal precisely in the predetermined area. [0003] In order for the processed centralized compliance mechanism to fully realize each function, it is necessary to precisely bend different positions of the metal sheet, and not to deform other fixed positions, otherwise the metal sheet will be useless. Contents of the invention [0004] The purpose of the present invention is to at least solve one of the technical problems in th...
