Accroding to the structure characteristics and using request of the hanger, analyzed the press process, through using hole deformation compensation method, determined an efficient process plan and component blank size, designed the practical die structure, satisfied the component using request, reduced the cost.

Based on the simulation of radial deformation of plunger couple of high pressure fuel injection pump used for common rail system,seven kinds of plunger couples were designed by using deformation compensation technology.

Structural optimization in line with the principle of deformation compensation is therefore conducted on base of the coupling effects contour plots,which is proved to be quite effective by compariso.

Based on the above, it researched the deformation compensation of the bracket .

Application of precompensation for deformation in diminishing the deformation of injection moulded products;

Based on the thermal deformation compensation,the rotary and stationary rings are optimized,and the thermal deformation before and after the optimization are attained and analyzed.
