Design And Research On The Multi-station Stamping Automatic Feeding System Of The Pin Chain Plate

With the continuous development of the stamping manufacturing industry,the traditional single-machine single-station stamping operation method is gradually replaced by the single-machine multi-station stamping operation method.With the continuous pursuit of stamping automation production,manual feeding has gradually been replaced by an automatic feeding system with high production efficiency,high safety and simple operation.Aiming at the multi-station stamping processing platform of a chain manufacturing chain of a chain manufacturing company,the paper proposes a general design scheme of an automatic feeding system,which is composed of a storage device,an automatic feeding device and a control system.The automatic production of the chain link plate in the multi-station stamping operation can avoid the shortage of labor caused by the shortage of human resources and effectively improve the efficiency,safety and reliability of the stamping operation.It is an upgrade and transformation of similar stamping production lines.Providing valuable reference is of great research significance.The main research contents of the paper are as follows:(1)Based on the analysis of the multi-station stamping process of the pin chain chain plate and the structural characteristics of the processing platform,the overall scheme design of the automatic feeding system was started from two aspects of mechanical structure and control system.In terms of mechanical structure,different schemes are proposed to link the blanking process with the subsequent stamping process.After comparative analysis,an automatic feeding scheme combining a storage device and an automatic feeding device is selected.In terms of control system,PLC was selected as the control center,and the overall scheme design of the control system was completed with the help of servo control system,related sensors and touch screen.(2)The mechanical structure of the storage device and the automatic feeding device are designed in detail;the relevant equipment is selected and checked according to the requirements of the actual working conditions;the three-dimensional model of the automatic feeding system is established with the help of Solidworks software.The genetic algorithm was used to optimize the structure size and material selection of the cantilever beam based on MATLAB analysis software.At the same time,the optimization results were verified by ANSYS analysis software.(3)Based on the analysis of motion requirements,the research on motion planning and motion timing design of automatic feeding system is carried out.With the help of ADAMS software,the kinematics simulation of the automatic feeding system is performed.Based on the simulation calculation results,the feasibility of the preliminary planning and the possibility of optimization of the timing design of movement are analyzed.Based on the final planning results,research was carried out on the grip stability at the execution end to further verify whether the gripping mechanism of the automatic feeding device is reliable.(4)According to the analysis of the basic requirements and functions of the control system,the overall architecture of the control system is designed.With PLC control as the core,the servo control system is researched,and related equipment is selected and checked.According to the design of the working mode and the requirements of the actual working conditions,the PLC control program and man-machine interface are designed in detail.Finally,prototype production and related debugging are performed to verify the performance of the automatic feeding system.
