800  traversing  rewinding machine

The 800 traversing -rewinder  machine includes: a fixed base frame, a mobile frame, a wire arrangement mechanism, a transmission part, a wire drum expansion and contraction part, a strips pressing part, and an electric control cabinet.

Base frame and mobile frame: Made of high-quality steel, welded by CO2 gas shielded welding, and processed after aging treatment. The mobile frame is installed on the linear guide rail on the low frame, and reciprocates through the ball screw connection transmission to complete the wire arrangement action, ensuring the stable and reliable performance of the whole machine after assembly.

Wire arrangement mechanism adopts PMI linear guide rails and ball screws to ensure the accuracy of strips arrangement. A servo motor is installed at one end to drive the mobile frame of the strip-receiving and strip-releasing machine to reciprocate wire arrangement through the ball screw.

Transmission part The power is transmitted from the output of the 15kw servo motor to the reducer, and the reducer is transmitted to the spindle. Finally, the coupling disk at the front end of the spindle drives the strips-receiving and wire-reducing reel to rotate.

Wire drum expansion and contraction part The whole is divided into 4 plates. In order to improve the expansion and contraction roundness, a slider mechanism is used for expansion and contraction. The expansion and contraction spindle sleeve adopts a detachable structure and is connected to the transmission spindle keyway bolt. The inner sleeve at the front end of the transmission main shaft expands and contracts, and the expansion and contraction of the expansion and contraction part is controlled by turning the handle.

Strip pressing part When the wire arrangement is used, the wire pressing part is at a high position. When the strip arrangement function is not used for winding, the strip passing speed regulating lifting frame is at a high position, the strip pressing wheel is pressed down to the specified position, and after winding to a certain number of layers, the wire pressing wheel rises a certain distance, and the touch screen displays the current strip  pressing wheel position in real time. The distance between the strip pressing wheel shaft and the winding reel makes the wire taking-up positioning wheel and the winding reel at a suitable distance to ensure that the strips does not collapse, and the up and down adjustment is controlled by a stepper motor lead screw.

Wire passing wheel at the feeding end. The strips feeding guide wheel part is installed on the sliding table lifting as a whole, so that the strips feeding fixed wheel is as close to the strips reel as possible to ensure the quality of wire arrangement.

。

1. Control method:
2. The striparrangement collects the encoder signal of the servo stripstaking-up motor through the PLC to calculate, so that the strips arrangement mechanism keeps synchronization with the wire taking-up.
3. The speed of the stripis collected by driving the photoelectric encoder through the strip wheel to feedback to the PLC to achieve the accuracy of the meter and wire speed.
4. Strip traversing arrangement technology:

After years of careful research, development, practice and summary by our company, an effective wire arrangement method has been developed to effectively solve the problem of strip advance or lag caused by strip stacking and reversing during the wire arrangement process, and the current position of the strip  arrangement is displayed in real time to ensure the flatness of the wire arrangement.

3.single channel eddy current online detection mechanism for strip:

1. Introduction:
2. The products are widely used in power, nuclear energy, aerospace, military industry, metallurgy, and machinery manufacturing. In recent years, the company has made continuous achievements and has taken the lead in launching multifunctional intelligent eddy current flaw detectors, multi-frequency multi-channel eddy current flaw detectors, dual-frequency dual-channel eddy current flaw detectors, pipe and rod automatic flaw detection systems, and aircraft wheel hub automatic flaw detection systems in China. The company and many colleges and research institutes have jointly developed high-speed flaw detectors and ultra-high-speed online eddy current flaw detectors that can reach 3,200 meters per minute, filling the domestic gap and effectively promoting the development of my country’s testing industry. The various series of eddy current flaw detectors produced by the company are well-known international and domestic brands. The products are exported to Germany, the United States, the Middle East, Japan, South Korea and other regions and are widely used in the domestic metal manufacturing industry.

2. Working principle of eddy current flaw detector:

Eddy current testing (Eddy Current Testing) is one of many non-destructive testing (NDT) methods. It

applies the basic theory of “electromagnetism” as the basis for conductor detection.

Eddy current testing is to bring a conductor close to a probe with alternating current to establish an alternating magnetic field. This alternating magnetic field passes through the conductor and generates electromagnetic induction with it, establishing eddy currents in the conductor. The eddy currents in the probe conductor will also generate their own magnetic field. The effect of the eddy current magnetic field will also change the strength of the original magnetic field, thereby causing changes in voltage and impedance. Therefore, when defects appear in the conductor or the measured metal material changes, it will affect the intensity and distribution of the eddy current. The change in eddy current will cause changes in the voltage and impedance of the detection coil. Based on this change, the existence of defects in the conductor and the defects of the metal material can be indirectly known.

3. Inspection object
