The Research And Development Of Full-automatic Polishing Machine For The Stainless Steel Cup-shaped Pieces

The cup is one of people’s daily articles. Stainless steel cup has become increasinglypopular with its strong and durable, beautiful and elegant characteristics. This full-automaticpolishing machine for the stainless steel cup-shaped pieces with a new highly efficient andenvironmentally protective technology realizes full automation of polishing process, greatlyimproves the efficiency of existing polishing, solves the bottleneck problem in the process ofstainless steel cup production, and greatly reduces production costs, then produces the hugeeconomic benefits. The equipment does fully conform to the concept of safety andenvironmental protection, there is a complete isolation between the operator and polishingwheel in case of breathing dust. The metal polishing dust can be on centralized processing inthe polishing process without any environmental pollution and with huge social benefits.This paper introduces the system design and implementation methods on full-automaticelectrical control system of polishing machine which takes advantage of PLC and monitoringconfiguration software. The equipment hardware is configurated in this system according to thepolishing technology, combined with the mechanical design. The equipment configuration ofdirect control layer and Operation monitoring layer is confirmed according to the requirementsof raw material production process to the control and management. The man-machine interfaceis responsible for controlling parameters input, state monitoring and data processing, which isbased on the data interaction of RS-485MODBUS agreement with PLC; As the core of thewhole machine, PLC is responsible for controlling each actuator output according to thereceiving of the sensor feedback signal and the predetermined programme; X and Y servo driveuses Pt position model，it produces the highest200KHz control pulse using the PTO controlmodule, and feeds back the current position information cooperating with servo motor ownincremental encoder, achieves the requirements of high-speed, reliable, accurate control.Position switches are installed on both sides of X, Y actuators for the position protection and thesafety in production; Frequency converter is used to control the transmission of materials withspeed, according to the actual production condition, the user can operate directly through thepanel knob regulation.The general structure design idea of the program is to divide each functional division intomodules, call different subroutine according to the different operating modes, and realize themodular programming. Combined with stainless steel polishing technology process and itscontrol, management requirements, system software configuration provides a friendly, convenient operation environment. This equipment mainly uses computer solidworksthree-dimensional entity design software, TwidoSuite programming software, Vijeo Designerman-machine interface programming software and LEXIUM23SET UP servo driveconfiguration software to conduct product design and development.After practically testing and production operation, this equipment can realize the strictprocess requirement, offer the monitoring, control and data collection functions for theproduction process. The equipment can not only satisfy the polishing requirement of straighttube cup form, also can be used in the inclined plane cup polishing of a variety of specifications.When polishing the cups with different specifications, we don’t need to change hardware andcircuit, just need to set the corresponding parameters in the touch screen, and replace thecorresponding specification grinding head, and then realize the automatic polishing.Therefore, the birth of full-automatic stainless steel cup polishing machine must bringabout a revolution in mechanical polishing industry of stainless steel cup, and its marketprospect is very broad.
