Description

Technical Field

[0001] The invention belongs to the technical field of sawing machines, and in particular relates to a variable speed sawing control system for sawing machines. Background Art

[0002] The servo position control module of the sawing machine system adopts a position control that combines sampling interpolation and predictive control. Due to the electromagnetic mechanical hysteresis and motion inertia, it is almost impossible to control the movement of the feed slide by 0.1mm by "on" and "off". In order to ensure the minimum feeding length and feeding accuracy, the rear clamp makes the feeding slide retreat to the LK position, and then moves forward to the predicted position LT to close the feeding solenoid valve. The rear clamp is clamped when the feeding cylinder stops moving. Sawing machines are simpler machine tools, and users will not require their sawing machines to have the functions of a machining center. Computer-controlled sawing machines not only improve the efficiency and quality of sawing for users, but more importantly, the network function of the computer will make sawing more closely connected with the rest of the CIMS and more convenient to manage. At present, the modern manufacturing industry is developing rapidly, and energy conservation and environmental protection have also become a major indicator. On a sawing machine, the life of the saw blade is extended, and the economic benefits and environmental protection effects will be greatly improved.

[0003] Conventional sawing machines, such as a band saw with a chip collection function and publication number CN107378117A, have a chip collection function that can accumulate most of the debris in the chip collection groove, and can automatically sweep it away through the scraper plate when necessary, which is very convenient and can collect related waste materials, but there is no related processing operation on the sawing equipment related to the sawing machine. In actual working conditions, due to factors such as uneven materials and uneven shapes of the workpieces being processed, the sawing force changes during sawing, which affects the fatigue life of the sawing device. If the feed speed is only set according to the maximum force point of the workpiece, it will greatly affect the sawing efficiency and speed. Therefore, realizing the intelligence of the sawing machine can not only improve work efficiency, but also increase the service life of the sawing device and increase economic benefits. Summary of the invention
