The piston pump is a hydraulic system power generating element, modern hydraulic components used in a very wide range of hydraulic components one. The key components of the plunger assembly as the piston pump, its performance requirements correspondingly is improved. The plunger assembly slipper and plunger by compressional deformation shut connection. Shut technology the key technologies of the production process is a piston pump and piston pump to produce the technical threshold, the plunger assembly shut very important quality, it affects the entire piston pump performance and life. Therefore, studies based on spinning technologies piston pump slipper shut molding characteristics, in order to shorten the processing cycle, improve the machining accuracy and accelerate the innovation of our piston pump technology has important significance.This article will study for the piston pump slipper shut molding characteristics, research, analysis, tracking shut machine slipper at home and abroad the latest developments related technology research; spinning technology characteristics and course of development; characteristics of different spinning and the range of applications and different process parameters of the spin pressure and workpiece quality impact analysis provides a theoretical basis for a reasonable choice of parameters for the spinning process.Completed slipper piston pump design, including the choice of parameters and check the derivation of the formula. Also Slipper shut machines the Rack shape and determine the size of the rack load analysis and checking of the rack structure in the form of confirmation, rack of strength and stiffness. Determine the state of stress and assumptions of the metal spinning deformation zone, spinning pass and spinning slipper shut process. Shoe cuffs deformation process in different states, respectively, with the spin pressure calculated in the shoe spinning cuffs process.The last use of Solidworks three-dimensional modeling technology and ADAMS simulation technology piston pump slipper spinning shut kinematics analysis, and simulation results are compared with the theoretical, to verify the theoretical scheme is feasible.
