This paper presents the heat conventional spinning forming process used for semi finished flexspline products of closed harmonic gear drive.

The forming scheme which utilize slab blank, straight and small coning mandrels, conventional spinning and power spinning is adopted.

Design of the involute trace of multi-pass conventional spinning and application in numerical simulation;

In this paper,the recent research upon spinning technique covering conventional spinning and power spinning are summarized, and an approach to the trend of developing metal spinning technology is made.

This paper advances the calculating method and formulas of blank diameter of thin-wall round workpiece with arbitrary shape generator under conventional spinning process,which provides evidence and assistance for actual calculation in workshop.

Improved design and dynamic characteristic analysis of the vessel-end spinning machine for hot spinning;

Study on hot spinning technology of tubular workpieces for TA15 titanium alloy;

The die device for wheel rim was designed according to the structural characteristic of wheel rim of TC4 titanium alloy,hot deformation behavior was investigated by tensile experiment,and the causes of forming defects during hot spinning were analyzed,based on which the proper process scheme of hot spinning for wheel rim was obtained.

Nanosized zeolite T with the mean size range of 80～150 nm was synthesized by conventional heating or microwave heating at 85 ℃ with the addition of 10% template.

Compared with the conventional heating method, not only was crystallization time reduced over 80%, but also the crystallinity and surface area of crystals were improved.
