Mjk90-2 Cnc Spring End Grinding Machine Control System Was Successfully Developed

After a long time of painstaking research and combined with many years of successful

experience in the field of CNC system, composed of Delta-Cimic electronics Nanjing branch of type MJK90-2CNC spring end grinding machine control system near future success.

Spring as a standard, widely used in various machines, especially its accuracy for the performance of the machine is very important. Spring production process is divided into four steps: Spring - - - - - face grinding deburring heat treatment. Spring end grinding machine is the spring end grinding, so that the spring height and finish process to meet the requirements of. It is a spring production process key equipment, its precision directly determines the quality of springs.

In the latest study of MJK90-2 CNC spring end grinding machine control system configuration is reasonable, have great originality. This set of equipment is set by the delta mechanical and electrical products, EH series PLC control of 4M series inverter, monitored by Delta DOP A series 10.4inch TFT screen. Head position detection is achieved by rotating speed pulse encoder returned by PLC high speed counter calculated. The other two encoder are respectively for upper and lower compensation of motor position detection. Encoder input for the AB, EH PLC and AB Road 4phase pulse counting, counting the frequency can reach 200KHZ and single phase. The spring pressure is applied through current transmitter site signals into0 20 mA, and then access the PLC O4AD-H module.

So excellent configuration is its operating principle is not divided. The system begins to work, the volume spring machine spring production out of the blank into the end face grinder left ( or right ) loading disk, start the machine, press the left loading tray into the button, so that the left tray into the area, when the left tray motor rotating rapidly, at the same time grinding head fast rotation and downward run of spring face grinding. When grinding, right loading tray rotates slowly, so that workers installed spring blank, improve production efficiency. Grinding is divided into two steps, first rough grinding to size, and then grinding (feed motor is not running) in order to improve the smoothness of the spring end. Grinding is completed, left tray automatically exit the discharge, the right tray into the area, to grinding.

The equipment in addition to a good configuration and performance of the system, the operation mode is also fully consider the requirements of customers, the artificial intelligence and machine intelligence perfect combination. The control way is divided into manual control and automatic control, manual control mode at the same time on any one motor adjustment; automatic operation device according to the set process grinding spring, there are strict transport relation, and can be suspended at any time, equipment for fine adjustment, can continue after grinding.

At present, the PLC control system has been adopted by a customer of the strict testing, not only such, test results also show its various technical indicators have reached the same industry leading level, is no mass production. The main advantages are as follows:

Using PLC control, grinding head feed, automatic reset, the feed speed can be adjusted automatically, can design of grinding wheel wear compensation (manual or automatic )

Adjustment of the parameters through the touch screen to operate, convenient and intuitive, and can monitor the state of machine production, machine malfunction alarm, intelligent program of high

Double disk circulating conversion, continuous grinding, can be left or right tray separate feed grinding, strong applicability

Double disc conversion, loading, unloading cylinder, pressure, adjustable speed, high automation degree; wheel loading, unloading, stent assisted, rest wheel without opening table, time saving, labor saving.
