On the basis of BT drive control technology, the special program of punch servo drive controller is written according to the use requirements of domestic turret punch. Drive controller core components are imported components, precision and stability and reliable. The punch servo motor adopts the circulating oil supply cooling mode of the oil cooler, which has the advantages of low temperature rise and strong overload capacity, and solves the trouble of frequently replacing the coolant of the water cooler in cold areas in winter.
3. Transmission mechanism:
The cutter head is tempered and tempered with 45 # carbon steel. After turning and milling, the cutter head is surface treated by a large CNC plane disk grinder to ensure the flatness and smoothness of the upper and lower surfaces of the cutter head. Special fixture for pair positioning hole processing, to ensure the coaxiality of the upper and lower die positions; Using thin tower inlaid cutter head structure, while reducing the cutter head weight, still maintain the long guide structure, to ensure the guide stability of the mold, the company is equipped with large imported (Swedish Hexagon) three coordinate measuring instrument, cutter head after testing qualified assembly (the cutter head positioning hole indexing value other measuring tools can not be detected). The cutter head rotation adopts the turbine worm reducer, double chain transmission mode, the reducer is installed inside the body, enhance the stability of transmission and displacement accuracy; Cutter head adopts large cylinder seat, double cylinder positioning design, strong synchronization, stable and accurate positioning, while avoiding the wear of the cutter head side sleeve. The rotating station (rotating station) adopts synchronous belt transmission mode, which has the advantages of fast transmission speed, high precision and low noise.
4. Feeding mechanism:
Y axis adopts integrated connecting plate, X axis square tube beam double guide rail design, after tempering treatment, on the basis of ensuring rigidity, reduce the dead weight of parts, more stable operation, more accurate position; Guide rail and screw are imported from Taiwan, guide rail and screw assembly adopt strict and scientific assembly process, the company is equipped with advanced laser collimator, laser interferometer and other testing equipment, to ensure the assembly accuracy, effectively improve the feeding accuracy and running speed. Adopts floating pneumatic clamp, with large clamping force and stable feeding; Integral dovetail type tray, good rigidity, easy to move clamp; When feeding, the clamp can automatically float down to facilitate the plate to enter the clamp mouth, greatly reducing the labor intensity of the operator. Multi-point automatic lubrication system is adopted for each moving part to ensure full lubrication and avoid the wear of moving parts caused by poor lubrication. All welding parts and casting parts are tempered to eliminate internal stress; Machining parts are all processed in the company (precision parts are all completed by the machining center), and assembled after qualified testing, which effectively controls the machining tolerance of each part and eliminates the accumulated tolerance generated in the assembly process of the parts
5. Work surface:
Adopt universal ball, brush mix, pneumatic lifting type working table, reduce the noise and vibration of the machine tool when working, play a good role in the protection of the plate surface, can effectively prevent the plate surface scratch. The special dustproof design structure of the working table can prevent the collision accident caused by too large clearance, and also play the role of dustproof to the guide rail and screw; Effectively prolong the service life of guide rail and screw. The periphery of the table and the surface of the hairless brush part of the stainless steel protection, beautiful and generous, strong and durable, to prevent the plate scratch the working table. Data line protection is changed from the traditional built-in way to the body side chain protection setting to reduce the gap of the workbench and prevent scraping board and collision board.
6. Control system:
Imported motherboard superordination machine type movement control CARDS, and cooperate with panasonic servo unit RTEX bus and using full closed-loop transmission signal, to avoid the step pulse transmission way signal lost, the phenomenon such as transmission delay, and no signal feedback, improved the signal transmission speed and accuracy, can effectively enhance the speed and precision of the equipment. The communication speed of bus control mode is fast and the period is short. In the multi-axis cooperative action, the accuracy of the coordination between the shafts is greatly improved. The control information is sent in the form of instruction packet, which is stronger than the traditional pulse control, and can effectively avoid the influence of large power equipment on the control system. All control functions are transmitted through network cables to avoid the workload of troubleshooting caused by excessive data lines. The upper computer control system can access or write the information it needs through the RTEX bus in time, and the obtained information can also be exchanged or stored with the factory management system, so as to facilitate the relevant personnel to timely understand the operation of the equipment dynamic and production status; The bus connection mode between the upper computer and the servo motor driver can make each servo motor work better.
7. Programming software:
The use of Windows platform display, suitable for ordinary people's use habits, easy to operate; Processing program graphical display, processing products at a glance, reduce the possibility of processing error; Software compatible with G code programming, CAD programming and CNCKad programming, convenient for different operators of the programming habits. With automatic parameter matching function: the upper computer control system can automatically adjust the motor parameters according to the processing plate size, plate thickness and processing technology requirements and other characteristics, to make the corresponding feeding speed, stamping speed adjustment, so that it can work in the optimal condition.
