Variable-cross-section large part forming process method

Abstract

The invention discloses a variable cross-section large part forming process method which comprises the following process steps of: segmenting a part model: classifying a design model of a variable-cross-section large part according to the shape and / or size, determining a division surface, and segmenting the design model according to the division surface to obtain a segmented model; conducting blanking and rough machining: selecting a blank for blanking, conducting rough machining on the blank, and obtaining rough-machined parts; splicing and installing rough-machined parts: conducting butt joint on the butt-joint faces of the two rough-machined parts to be connected, connecting and fixing the two rough-machined parts, and obtaining splicing pieces; welding the splicing pieces: welding the butt-joint faces of the splicing pieces, and obtaining welding pieces; and conducting finish machining on the welding pieces: conducting finish machining on the welding pieces, and completing part machining. According to the variable-cross-section large part forming process method provided by the invention, the variable-cross-section large part is divided into parts with different cross sections, so that the machining cost is reduced to a certain extent, and the raw material utilization rate is increased.

Description

technical field [0001] The application belongs to the technical field of parts manufacturing, and in particular relates to a forming process method for large parts with variable cross-sections. Background technique [0002] In the existing technology, when processing large parts with variable cross-section, the overall processing method is generally adopted, and it is often impossible to select suitable common blanks, and the material selection process will take time. Excessive size or irregular shape will cause waste of raw materials and increase the material cost of the processing process to a certain extent. [0003] To sum up, there are technical problems of low raw material utilization rate and high time and processing costs in the processing of large parts in the prior art. Contents of the invention [0004] In order to solve the above technical problems, it is very necessary to propose a process method that improves the utilization rate of raw materials and reduces...

Problems solved by technology

[0002] In the existing technology, when processing large parts with variable cross-section, the overall processing method is generally adopted, and it is often impossible to select suitable common blanks, and the material selection process will take time. The size is too large or the shape is irregular, resulting in waste of raw materials, which increases the material cost of the processing process to a certain extent

[0003] In summary, there are technical problems of low raw material utilization rate and high time and processing costs in the processing of large parts in the prior art
