The choice of spinning process plan?

Selection of spinning process plan

The choice of spinning process scheme is the first problem encountered in spinning. After the production task of the spinning parts is determined, according to the material properties, structural form, dimensional accuracy, surface quality, required equipment performance and use, and production economy of the spinning parts, comprehensive selection is made to select the best spinning process. Program.

Spinning mode selection

The choice of spinning method is mainly based on the shape of the shape, the blank size, and the process characteristics. For the cylindrical member, generally refers to the use of positive or negative spinning, and for the tapered member and the curved member, generally refers to shear spinning or ordinary spinning, or refers to the combination of shear spinning and ordinary spinning. In addition, both the strong spinning and the ordinary spinning have the distinction of internal spinning and external spinning.

Blank processing

The original state of the blank has a great influence on the quality of the spinning parts. The selection of the blank blanking process may result in a decrease in the amount of the parts and even scrapping. Therefore, when considering the process plan, sufficient attention should be paid.

The high elongation, high profile shrinkage and low work hardening index are the process indexes for making the metal material have good formability. Which heat treatment method is adopted should be determined according to the blank material.

Selection of spinning equipment

In order to implement the selected process plan and spinning process specification, it is necessary to select a suitable spinning machine and select reasonable process equipment to produce high quality products and obtain high technical and economic effects.
