Problems solved by technology

This processing method has the following deficiencies: 1) Due to the complex processing procedures, the production cycle of each process is long, and a lot of time is spent in the processing process; 2) Due to the large curvature and complex shape of the sample blank, it is difficult to adjust the chemical milling allowance line on the CNC machine tool. When scribing, errors often occur, resulting in inaccurate chemical milling areas; 3) It is difficult for parts manufacturers to process the outer edge of parts

Embodiment Construction

[0014] Such as figure 2 Shown, a kind of chemical milling template processing method is characterized in that comprising the following steps:

[0015] 1) Add process information such as chemical milling allowance line, part edge line, positioning line, pin hole, etc. to the engineering data set, complete the manufacturing data set, and provide the manufacturing data set to the tooling department, parts factory and other units for tire molding manufacturing;

[0016] 2) According to the different milling surfaces, use the curved surface unfolding method to unfold the inner surface, outer surface or middle surface of the part, and at the same time transmit the process information such as the edge line of the part, the milling allowance line, and the positioning hole to the unfolding On the surface after that, an expanded data set is formed;

[0017] 3) Provide the expanded data set of the chemical milling part to the part manufacturing unit, and the part manufacturing unit us...

Abstract

The invention relates to a processing method of a chemical milling template, which comprises the following steps: 1) preparing a data set; 2) expanding the data set; 3) expanding the data set and manufacturing a chemically milled blank; 4) unfolding a transitional template and transferring the transitional template to the formed blank; 5) forming a view port on the blank; and 6) forming the chemical milling template. By adopting the method, the production procedures can be simplified, the manufacturing cycle of the chemical milling template can be shortened, the step of treating excessive chemical milling threads through a numerically controlled integrated machine can be eliminated, molds for outer edge cutting of parts and outer edge cutting procedures for the parts can be eliminated, and thus the processing speed can be increased greatly.

Description

technical field [0001] The invention relates to a method for processing a chemical milling template, which is used for rapidly processing a chemical milling template. Background technique [0002] For the chemical milling parts or titanium alloy parts with large curved surface, in many cases, the chemical milling template and the nesting template of the part should be provided. like figure 1 As shown, the chemical milling sample is formed first and then chemical milling. This kind of sample requires the part workshop to provide the real sample of the intermediate process, the raw material sample, etc., and at the same time needs to complete the scribing of the chemical milling allowance line in the chemical milling area, open the viewport and parts. , Cutting of the outer edge of the molded tire. Under digital conditions, the manufacturing data set is provided by the manufacturing data center, and the relevant units design and cut the outer edge of the mold tire according ...
