Embodiment 1

[0068] see Figure 1-19 , a three-dimensional simulation processing tool for special-shaped stainless steel thin-walled parts, which includes a large-face inner cavity processing tool 3 for processing and clamping the large end surface 103 and U-shaped inner cavity 102 of the blank 1; 1 small end face 101 is the small surface shape processing tool 4 when processing and clamping; the small surface shape processing tool 4 is matched with the pressing cover plate 5 for pressing the blank 1. Through the above-mentioned processing tool, it can be used to process the blank 1, and finally realize the processing and forming of special-shaped stainless steel thin-walled parts.

[0069] Further, the large-surface inner cavity processing tool 3 includes a rectangular clamping base 303, the central part of the rectangular clamping base 303 is processed with a knife relief groove 302, and the contour line of the knife relief groove 302 is consistent with the blank. The contour of the U-sh...

Embodiment 2

[0074] The method for processing special-shaped stainless steel thin-walled parts by using the three-dimensional simulation processing tooling comprises the following steps:

[0075] Step 1: tooling production; according to the structural size of the processed special-shaped stainless steel thin-walled parts, corresponding large surface inner cavity processing tooling 3, small surface shape processing tooling 4 and pressing cover plate 5 are made;

[0076] Step 2: blanking of the blank 1; select a plate with a certain thickness and corresponding size, and cut the plate into a blank 1 with a U-shaped inner cavity 102 by means of water jet cutting;

[0077] Step 3: Preliminary clamping and fixing of blank 1 and large surface inner cavity processing tooling 3;

[0078] Step 3.1: Machining a plurality of clamping threaded holes 104 for matching with the first through hole 301 of the large surface inner cavity processing tooling 3 on the small end surface 101 of the blank to be pro...

Embodiment 3

[0095] The method for processing special-shaped stainless steel thin-walled parts by using the three-dimensional simulation processing tooling comprises the following steps:

[0096] Step 1: tooling production; according to the structural size of the processed special-shaped stainless steel thin-walled parts, corresponding large surface inner cavity processing tooling 3, small surface shape processing tooling 4 and pressing cover plate 5 are made;

[0097] Step 2: blanking of the blank 1; select a plate with a certain thickness of 65 mm and corresponding size, and cut the plate into a blank 1 with a U-shaped inner cavity 102 by means of water jet cutting;

[0098] Step 3: Preliminary clamping and fixing of blank 1 and large surface inner cavity processing tooling 3;

[0099] Step 3.1: Machining a plurality of 10-M12 clamping threaded holes 104 for matching with the first through hole 301 of the large surface cavity processing tooling 3 on the small end surface 101 of the blank...

Abstract

The invention provides a three-dimensional simulation processing tool and method for special-shaped stainless steel thin-walled parts. The small surface shape processing tool for processing and clamping the small end surface of the piece; the small surface shape processing tool is matched with the pressing cover plate for pressing the blank. This tooling can be used for auxiliary processing of thin-walled parts such as pipes, can complete curved surface processing, and improves its processing quality and efficiency.

Description

technical field [0001] The invention relates to the technical field of processing thin-walled parts, in particular to a three-dimensional simulation processing tool and method for special-shaped stainless steel thin-walled parts. Background technique [0002] The takeover parts are GE's long-term products, and its component parts "insert block" are typical thin-walled parts with "irregular surface structure" and the material is stainless steel, which has high dimensional accuracy and geometric shape requirements. The processing difficulty is high, and the added value is higher. [0003] At present, the company purchases such parts as finished products, which costs a lot of money and greatly increases the cost. It does not meet the company's lean production requirements and also violates the company's interests. Because the part is a special special-shaped stainless steel part, and it is very thin and has a weird shape, it cannot be clamped directly; therefore, tooling must ...
