Application of TETRANCA frequency inverter in punching industry
1. Industry Overview
Punching production is mainly for sheet metal. Through the mold, can make the drop, punching, molding, deep drawing, trimming, fine blanking, shaping, riveting and extrusion parts, etc., widely used in various fields.
At present, the domestic high-speed punch press research and development basically with the development of the domestic stamping market to keep pace with the domestic punch press manufacturers want to compete with the international first-class brands in another area is technological innovation, such as control systems, material technology, mold technology. Frequency converter, as the drive component of press control, is also derived from the generalization of specialized frequency converter. The performance of frequency converter plays a decisive role in the output stability, accuracy, reliability and load capacity of high-speed press.
2. Equipment Requirements
At present, the high-speed punch presses on the market have the following characteristics:
(1):The equipment body is made of high-strength cast iron, which is annealed, vibrated to eliminate stress and other processes, so as to ensure long-term accuracy.
(2):Dynamic balancing system is adopted to minimize the vibration of the press to the extreme point, thus ensuring the precision of the pressed products.
(3):Adopting frequency converter speed control system, the stroke speed is adjustable, the stamping frequency is high, the noise is small, and the speed is stable, zero error, suitable for a variety of stamping process and other characteristics. Equipped with microcomputer control unit, all information is displayed on the desktop, the operation is centralized, convenient, and easy to maintain.
3. Solution
Performance characteristics of TETRANCA T510 vector inverter TETRANCA T510 series vector inverter has been used in many machinery and equipment companies in large quantities, and fully meets the demanding requirements of punching equipment. T510 series vector inverter in the punching equipment has been used in many machinery and equipment companies in large quantities, and fully meets the demanding requirements of punching equipment. T510 series vector inverter in the punching equipment has the following unique advantages:
(1):Vector control response is fast, the low-frequency torque is large, and the output of all frequency bands is smooth, and the dynamic response of the torque is fast, and the speed stability is high. High precision. The overload capacity reaches 180% and the starting torque of 0.5HZ can output 150%, which can ensure the reliable and stable operation of the press. The output frequency is stable without fluctuation at the moment of press clutch closure.
(2):Scientific and reasonable speed tracking algorithm makes the frequency converter automatically track its current running frequency when the motor is not stopped, and it can stop and start in a hurry, and it can be started smoothly without fail when the motor is running inertially, which greatly improves the safety performance of the punch press.
(3):A variety of flexible control methods to meet the requirements of different complex working conditions.
(4):The structure adopts independent air duct design, the fan can be freely removed, good heat dissipation.
