Function operation speed regulation mode of automatic fiber cutting machine manufacturers
Taiwan group of automatic fiber cutting machine manufacturers have many laboratories in low-voltage electrical appliances companies, but only Tianzheng is the only laboratory that has passed the review by the China Laboratory Accreditation Committee in accordance with international regulations. The China Laboratory Accreditation Committee is an organization recognized by the International Laboratory Accreditation Cooperation Organization. Its assessment is in line with international standards and has international authority. The passing of this assessment indicates that Tianzheng products are produced and tested in accordance with international standards and can be unimpeded in the future. Entering the international market is of great significance for eliminating technical barriers in international trade after joining the WTO, and improving the international competitiveness of products. The overall layout of large-diameter steel pipes, the cutting steel pipe group group of automatic optical fiber cutting, the rotational feed speed is very high. Low, and large inertia DC servo motor has a large output torque when running at low speed. The larger peak value can reach more than 10 times the rated torque. It has strong overload capacity, allows a long continuous overload time, and the motor itself has a large inertia, which can directly drive the load. , No need for mechanical deceleration transmission chain. The motor adopts a built-in low-ripple tachometer motor. The output voltage of the tachometer motor is used as the feedback signal of the speed loop to form a high-gain speed loop to make the motor run smoothly in a wide range.
Taiwan group automatic fiber cutting machine manufacturer also has a pulse encoder disc as the position detection element in the motor to control the selection of the CNC system. Taiwan group automatic fiber cutting CNC cutting machine , Choose the CNC system supplied by FANUC. The basis for selection is the ability to control the movement of the cutting torch along the X and Z axes and the rotational feed speed of the steel pipe. The feed direction and the amount of feed meet one of the accuracy requirements. Because the accuracy requirements of the cutting machine are not as high as those of the machining center, so when choosing the CNC system, consider whether the cost performance is compatible with the requirements of the cutting machine to reduce the user’s Acquisition cost. When the steel pipe rotates and feeds to control cutting, the steel pipe's low speed and infrequent reversing determine its characteristics of stable load. According to its load characteristics, select the constant torque speed regulation method that adjusts the DC motor armature voltage. The speed regulation system of the microcomputer controlled motor needs to convert the analog voltage signal into a digital signal through the A/D converter and then send it to the microcomputer to start, stop, speed setting and other operation commands, which are input by the interface circuit 1. The speed can be given in the program, or it can be directly sent to the memory through the keyboard before each startup. The speed feedback adopts the tachogenerator to read the CPU through the interface circuit 2, in order to satisfy the static and dynamic of the system. Cutting ability, advantages and disadvantages. Jinfeng cutting machine not only has high production efficiency and low labor intensity, but also has high cutting accuracy. After cutting, the rod has accurate mouth shape and high quality, which reduces the grinding and repair work of the automatic fiber cutting groove of the group. . Through the numerical control system of the console, the cutting torch mounted on the machine performs plane geometric motion according to the input cutting parameters, and only the height of the cutting torch and the size of the flame and the walking speed of the machine need to be adjusted to realize the continuous cutting of the steel pipe. Steel pipes with a pipe diameter greater than Φ406mm are generally coiled pipes, and longitudinal welds are bound to exist.
