Pulling bolts generally use both ends of the set of wire round steel bolts, also known as wall bolts, but also useful flat ends of the long hole with a wedge-shaped iron inserted into the fixed wedge tight. Because the bolts are also a kind of railway fittings, the railroad parts are part of the railway line. The rails mentioned here include rails, sleeper, connecting parts, track bed, anti-climbing equipment, rail brackets and turnouts. As a holistic engineering structure, the rail laying on the roadbed, plays a guiding role in the operation of the train, directly under the enormous pressure of locomotives and their loads. Under the motive force of the train operation, its various components must have sufficient strength and stability, and the instrument ensures that the train operates at the highest speed, safe, smooth and uninterrupted.

Winding machine is no stranger to motor manufacturers. It is an indispensable motor production equipment. It mainly winds the coils of motors. It is often used in various brushless motors, transformers, reactors, etc. It can be said that electromagnetic components are required The products of the coil part all need to use the winding machine. So what is the working principle of the winding machine? What are the common precautions? Before starting the machine, fix the iron core mold to be wound on the bracket, input the program, adjust various parameters, including wire diameter, number of turns, speed, slot crossing, forward rotation and reverse rotation, etc., and then automatically through the programmable controller The numerical value is calculated and displayed on the touch screen. Start the spindle motor, first wind 2 to 3 laps at a slow speed, and after making sure that there is no problem, slowly increase the speed to high speed until the winding is completed, the machine automatically clamps the wire, a complete winding process is completed, and then repeat this action . 1. Before using the winding machine, you should first confirm that the electricity and compressed air are in place, and you can run the winding machine after manual reset. 2. When the winding machine is running, the staff must not put their hands into the area between the skeleton trough and the feeding tooling to avoid hurting their hands. 3. The placement of the mold must be accurate, and it must be checked first. In many cases, the mold is not installed properly, and the nozzle is easy to be damaged. If the mold is not placed properly, you should press the pause button to ensure that the installation is correct before starting. 4. If the thread is broken during the winding process, you should immediately press the pause button. Generally speaking, it may be that the thread barrel is stuck, the tensioner is not set properly, or the speed is too fast. After checking, you should wind the thread slowly to ensure Speed up no problem. 5. In the event of a power failure or an emergency, be sure to reset and clamp the wire again before restarting. 6. When the thread is almost used up, tie the new thread with the old thread and pull it to the guide pin before starting. Before changing the thread, touch the upper edge of the thread barrel with your hands to see if there are burrs or foreign objects, so as to avoid interfering with the normal state of the thread. operation, causing a disconnection to occur. Choose D & S Automatic, we will provide you with the best service.

In order to adapt to the processing technology of the coil, the automatic rewinding machine needs to be equipped with the spindle speed control function. The rewinding equipment should be processed by the type and configuration is also different. The types of spindle motors that we are more familiar with include AC motors, DC motors, and servo drives. For these three types of motors, the speed regulation methods used by these motors have their own characteristics. (1)The speed regulation method of AC motor: this kind of motor itself has no speed regulation function, it needs to realize the speed regulation function through the electromagnetic speed regulation device or install the frequency converter. In the winding equipment, we are more common in the frequency converter speed regulation function. In this way, the frequency converter is controlled by the control system of the winding equipment to make the motor have the function of speed regulation. This method also has a certain energy-saving effect. (2)The speed control method of DC motor: DC motor needs to convert the supplied power into DC power to drive the motor. Therefore, DC motors are equipped with DC speed control boards or brushless drives to drive and control the motor. Because of the small size of the motor, it is small winding The amount of applications in the equipment is relatively large. (3).Speed control method of servo drive motor: It is a precision moving part suitable for high-precision winding equipment. It is used in conjunction with a dedicated drive to achieve closed-loop operation control. The biggest feature of this type of motor is constant torque and closed-loop operation, which is used to meet Processing requirements for high-precision coils.
