Problems solved by technology

[0004] The disadvantage of this model manufacturing method is that the datum increases the scribing and shifting error through repeated transformations. During the initial processing, a large machining allowance needs to be left around the chemical milling figure, and then it is carried out again and again with a small feed rate. processing, and it is necessary to position the mold tire many times, and constantly cover the blank on the mold tire for comparison, which is very cumbersome

Embodiment Construction

[0016] A method for manufacturing a three-dimensional milling template of a sheet metal part of the present invention mainly includes six steps: 1. Use a transparent gelatin plate 2 to position and cover the surface of the mold tire 1 with the chemical milling pattern 7 . 2. Draw the chemical milling pattern on the gelatin board. 3. Paste double-sided adhesive tape 4 on the surface of the gelatin plate 2. 4. Position and cover the formed chemical milling sample blank 5 on the surface of the mold tire 1, so that the gelatin plate 2 with the chemical milling pattern 7 attached to the chemical milling sample The inner surface of the blank 5, 5, the chemical milling model blank 5 is separated from the mold tire 1. 6. Process and manufacture a chemical milling template according to the chemical milling pattern 7 on the gelatin plate 2 .

[0017] figure 1 Shown is a molded body 1 with a chemically milled pattern 7 and a transparent gelatin plate 2 . Firstly, the mold tire 1 is cl...

Abstract

The invention discloses a method for manufacturing a sheet metal part stereo chemical milling sample plate. Based on the advantages of flexibility, transparency and high sticking performance, a gelatin plate is attached to a die tire, line drawing is carried out, then the gelatin plate is transferred to a blank; a chemical milling graphic is transferred to the blank; and the chemical milling sample plate is manufactured. By adopting the manufacturing method, the sample plate blank and the die tie are only required to be positioned once; the method has the advantages of simple operation, high practicability and high efficiency; and convenience is supplied to manufacturing of the stereo chemical milling sample plate.

Description

technical field [0001] The invention relates to the technical field of aircraft manufacturing, in particular to a method for manufacturing a three-dimensional milling template of a sheet metal part. Background technique [0002] The production of the three-dimensional milling template of sheet metal parts is based on the mold tire with the part's milling graphics, copying its graphics to the blank of the sheet metal part milling template formed according to the mold tire, and then processing according to the graphics on the blank of the chemical milling template Complete the chemical milling template. [0003] In traditional production, it is usually first to draw the extension line on the molded tire according to the frame axis and the truss axis on the tire as the reference line, then cover the blank on the molded tire and position it with a pin, and cast the drawn reference line onto the blank superior. The blank is removed from the mold tire, and then covered with sulf...
