Support device for processing complicated shape punched piece and its producing method

Abstract

The present invention relates to a kind of support device for machining complicated shape punched piece and making process. The device includes several mutually inserted support boards with insertion notches for mutual insertion, and tops of the support boards are in the shape corresponding to that of the bottom of the punched piece. The device is made by means of the digital model in computer. The device can accurate and fast locate the punched piece in a simple and convenient locating process.

Description

technical field [0001] The invention belongs to the technical field of mold processing, and in particular relates to a supporting device for processing stamping parts with complex shapes and a manufacturing method thereof. Background technique [0002] In units without special stamping software, when performing laser cutting or three-coordinate measurement of sheet metal parts, the spatial direction of the stamping parts must be determined before processing or measurement. For sheet metal parts with complex shapes, positioning is very difficult due to their irregular shapes. At present, there are mainly two positioning methods: the first positioning method is to use the sheet metal stamping die to turn a plaster mold, so that the bottom surface of the plaster mold support is parallel to the bottom surface of the mold, so that the stamping direction of the workpiece can be determined. However, the use of plaster molds has the following disadvantages: [0003] 1. Since the p...

Problems solved by technology

[0003] 1. Since the plaster mold adopts the support method of surface contact, there are problems such as over-positioning;

[0004] 2. When the gypsum mold is manufactured, the gypsum will deform during the drying and hardening process (the volume of the gypsum will expand after chemical reaction with water), and the law of the deformation direction and degree of deformation is not easy to grasp, which makes the positioning of the workpiece inaccurate and the precision is not good. High, the linear coordinate error of individual points can reach as many as several millimeters, and there is no simple and easy way to compensate or prevent excessive deformation;

[0005] 3. After the gypsum is completely hardened, the gypsum mold needs to be trimmed manually before it can be used. The trial production process takes a lot of time;

[0006] 4. The positioning of plaster molds is inconvenient. When cutting parts, it is necessary to rely on marking lines to find the alignment and determine the origin of the program.

This positioning method is complex to operate, extremely inefficient, has high requirements on the technical level of workers, and cannot be mass-produced
