Problems solved by technology

[0004] 1. Due to the process steps of heating, stretching, bottom cutting and contour cutting, the production parts are operated on different equipment, and continuous production cannot be formed, so that the production process takes up more labor and equipment, and the manufacturing and processing costs are higher.
[0005] 2. Due to the heating process, or even multiple heatings, the waiting time between processes is longer, which limits the production efficiency of sheet metal parts
[0006] 3. Due to multiple clamping and fixing on d

Embodiment Construction

[0027] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0028] see figure 1 , a progressive die forming process for high-temperature alloy sheet metal parts with high flanging holes, including the following processes:

[0029] 1) Punch out the positioning hole 1, that is, place the material strip for making sheet metal parts on the workbench of the stamping equipment, and punch out the positioning holes near the two sides of the material strip;

[0030] 2) Press type 2, which is to move the material strip with punched positioning holes to the next second process, and use the above positioning holes as the positioning reference to press the indentation consistent with the outer contour of the prefabricated sheet metal parts on the material belt. , according to the structural characteristics of th...

Abstract

The invention relates to a molding process of a progressive die of a high temperature alloy sheet metal component with a high flanging hole is disclosed, comprising the steps of: punching a positioning hole; compressing; stretching; punching a small hole; preparing a chamfer; flanging; correcting; and cutting and forming. Compared with prior art, the invention adopts the molding process of the progressive die for continuously production to improve the work efficiency by times. The positioning hole is machined at the position close to the side edge on a strip to form a uniform positioning standard, thereby improving the positioning precision and ensuring the quality and consistency of products. In prior art, work finished by a plurality of devices is finished by one punching device, thereby saving the devices and labor occupied, reducing the production cost and meeting the requirements of batch production.

Description

technical field [0001] The invention relates to a forming process of a sheet metal part, in particular to a progressive die forming process of a high-temperature alloy sheet metal part with high flanging holes. Background technique [0002] Superalloy materials refer to alloys with certain mechanical properties, oxidation resistance and corrosion resistance at temperatures above 650 °C. At present, a large number of sheet metal parts made of this material are used in aviation and aerospace equipment. In order to ensure the safety of the equipment, there are strict requirements on the thinning and cracks of this type of sheet metal parts during processing, and The sheet metal process of the superalloy material itself is poor, and it is easy to crack during bending, punching or stretching. When the sheet metal part has high flanging holes, its forming is more difficult. At present, the forming process often used for high-temperature alloy sheet metal parts with high flanging ...
