Embodiment Construction
[0021] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.
[0022] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.
[0023] Such as figure 1 As shown, the drawing of the bent steel sheet is made into a plane drawing, and the flat steel sheet is first made according to the drawing, and then the finished flat steel sheet is first bonded to the FPC by a machine, and then pressed and fixed on the FPC by a pressing machine. On the FPC, use the mold to press and bend the steel sheet attached to the FPC to the part that needs to be bent to achieve the required ben...

The invention discloses a novel processing method for bending steel sheets. The drawing of the bending steel sheet is made into a plane drawing, and the drawing of the bending steel sheet is flattened, and the prepared planar steel sheet is bonded by a machine first. On the entire FPC, and then use a pressing machine to press it on the FPC; prepare a stamping die, and use the stamping die to perform partial stamping and bending of the steel sheet attached to the FPC; in the process of stamping and bending, it is necessary to use the mold The upper part of the structure is in contact with the FPC, and the FPC is compressed, and then the steel sheet part to be bent is squeezed down with a punch that is higher than the mold of the compressed part, so as to achieve the bending effect. The invention solves the problems of low efficiency, poor quality consistency, high scrapping rate caused by lamination deviation of steel sheets, and reduced service life of the press caused by manual single-piece hand sticking.
Description
technical field [0001] The invention relates to the field of bending steel sheets, in particular to a novel processing method for bending steel sheets. Background technique [0002] Bond the bent 3D steel sheet on the FPC. The traditional production method is to bend the steel sheet first, and then press the bent steel sheet on the FPC. Because the steel sheet is a special-shaped steel sheet after bending, the shape is irregular and cannot be machined. Bonding can only be done manually by hand. When pressing, the special-shaped steel sheet must be pressed together, because the bent steel sheet is not a plane, but the pressing machine is a plane, so it is necessary to use a jig to separate the different parts. The steel sheets that are bonded to the FPC and are no longer on the same plane are pressed together. This process is inefficient and consumes a lot of manpower and material resources. At the same time, due to manual single-piece hand-sticking, the product consistency i...
