Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] Such as figure 2 Shown is a schematic diagram of the first implementation of the flying shear control system of the present invention. In this embodiment, the flying shear control system 20 includes a main shaft, a slave shaft, a reference position acquisition module 21 , a curve interpolation module 22 and a servo drive module 23 . Wherein the main shaft rotates according to the set track and the slave shaft is fixed with a cutter for cutting the material to be cut, and the rotation of the slave shaft drives the cutter to cut the material conveyed on the conveying device. In this embodim...

The invention provides a flying shear control system, and further provides a control method corresponding to the flying shear control system. The flying shear control system is used for shearing materials conveyed by a conveyor, comprises a driving shaft and a driven shaft, and further comprises a servo actuator, wherein the driven shaft rotates along with the driving shaft according to preset tracks, and a tool is fixed on the driven shaft; the servo actuator comprises a reference axis position acquiring module, a multi-time curve interpolation module and a servo drive module; the reference axis position acquiring module is used for acquiring the position of the driving shaft; the multi-time curve interpolation module calculates the operation position of the driven shaft according to the operation position of the driving shaft and inputs the operation position of the driven shaft to a positioning ring of the servo drive module; and the servo drive module outputs a control signal to a servo motor according to inputting of the positioning ring. Because driving shaft position acquiring, interpolation calculation and servo driving are integrated, unreliable factors in the instruction transmission process are reduced, reliability of flying shear control is improved, and meanwhile cost is saved.
Description
technical field [0001] The invention relates to the field of servo motor control, and more specifically, relates to a flying shear control system and method. Background technique [0002] Flying shear is a kind of shearing machine for transversely shearing rolled workpieces. It can quickly cut iron plates, steel pipes or paper rolls, etc. It is widely used in metallurgical steel rolling, papermaking and other production lines. [0003] With the continuous upgrading of industrial automation and the increasingly complex process of automation products, in order to meet the requirements of special shape and process of products, some motion controllers have added multi-axis curve interpolation control. Such as figure 1 As shown, it is an example of a traditional multi-axis curve interpolation control scheme. The motion controller 11 is used to process the position feedback of the actuator, and the servo amplifier 12 is used to control the motor transmission. [0004] However, t...
