Problems solved by technology

However, the entire edge of the invention is all zigzag sheet metal, so it is still easy to cause the positioning and forming of the sheet metal in the mold to be unstable, which may cause damage to the mold

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] The invention discloses a method for determining the layout of sheet metal with a composite shape. The technical solution is mainly to set the layout diagram based on the material control area. The definition of the material control area is as follows: according to the basic shape line of the sheet 3.1, The rear sheet material line 3.2 and the drawbead outer contour line 3.3 determine the material consumption control area; the material consumption control area includes the first straight line segment perpendicular to the sheet material feeding direction on the sheet material basic outline lin...

Abstract

The invention discloses a layout determination method, a structure and a stamping manufacturing method of a composite shape sheet. The stamping manufacturing method comprises the steps of determining a material consumption control area according to a basic sheet shape line, a drawing sheet line and a drawing bead outer contour line; accomplishing design of a layout drawing of the sheet by the control area; using a serrated sheet for a sheet side which is located in the material consumption control area and perpendicular to a blanking feeding direction; using a common linear or arc sheet for a sheet side which is located outside the material consumption control area and perpendicular to the blanking feeding direction; and stamping and manufacturing the composite shape sheet according to a design drawing. The method is simple and high-efficiency; reasonable arrangement of the layout drawing of the sheet is realized by defining the material consumption control area of the sheet; material consumption in a stamping process is effectively reduced; and difficulty of the serrated sheet for production and debugging of a die is reduced.

Description

technical field [0001] The invention relates to a sheet material, its layout structure, and a stamping manufacturing method, belonging to the technical field of stamping, and in particular to a method for determining the layout of a composite shape sheet material, its structure, and a stamping manufacturing method. Background technique [0002] It is estimated that the cost of materials accounts for about 70% of the cost of stamping parts. Usually, in the blanking process of stamping, the plate is cut into polygons with holes or without holes, which are used as raw materials for the post-stamping process. Reducing the material size of the blanking die sheet is an effective way to reduce the cost of stamping parts. [0003] For example, in the utility model patent of patent No. CN204365795U, Moreland Mold Co., Ltd. has developed a wave knife mold structure, which uses a zigzag blank to replace the traditional square blank, which can reduce the width of the blank, but it also...
