Hot plate welding hydraulic lifting mechanism
Abstract：PE pipe welding machine outdoor work, in order to optimize their impact on the process of welding butt welding quality, the kinematics and dynamics simulation for the existing semi-PE pipe welding machine hot plate lifting mechanism on the market, the simulation results draw more suitable parameters. The lifting mechanism simplified slider-crank mechanism, a hydraulic cylinder as a driver, even the hot plate uplift solid crank lever. Using Matlab / Simulink conduct its motion process modeling and simulation, analysis and optimization through simulation values for each parameter in turn, and then optimize the design of the structural design play a guiding role, both institutions. Matlab / Simulink with powerful computing capabilities for the kinematic mechanism can be in the respective positions, the kinetic parameters for solving the simulation results for each position is a function of time for the parameters, curve fitting parameters obtained final domain simulation results. This is convenient for the structural design of great significance.
