Transformer winding machine:




This model is generally used to wind small-size current transformers. The characteristics of small-size current transformers are generally wire diameter of enameled wire between 0.11-0.19mm, and the number of turns is large.


It requires accurate turns and fast winding speed.

What are the application scope and types of winding machines?

Winding machine: As the name implies, a winding machine is a machine that winds a linear object onto a specific workpiece.

  The scope of application of the winding machine:

   Most electrical products need to use enameled copper wire (referred to as enameled wire) to be wound into inductance coils, which requires a winding machine.

   For example: various motors, fluorescent lamp ballasts, transformers of various sizes, televisions. The mid-periphery and inductive coils used in the radio, the line output transformer (high-voltage package), the high-voltage coil on the electronic igniter, the mosquito killer, the loudspeaker, the earphone, the voice coil of the microphone, the various electric welding machines, etc. can not be cited one by one. All coils need to be wound with a winding machine.

   In the textile industry, cotton yarns, man-made fiber yarns, etc. are used to wind all kinds of yarn balls and frays suitable for textile machines. These require a winding machine to wind.

   Type of winding machine:

Commonly used wire winding machines are mostly enameled copper wire (winding inductance coils for electronic and electrical products), textile wire (winding yarn frays and coils for textile machines), and winding electric heating appliances. Electric heating wires and solder wires, wires, cables, etc.

  There are many types of winding machines, which can be classified into general-purpose and special-purpose types according to their uses;

R-type transformer winding machine

R-type transformer winding machine

        The cross section of an R-type transformer is like the letter R, so it is called an R-type transformer. The application of R-type transformers in high-power electrical appliances can reduce inrush current. R-type transformers are one of the dry-type transformers. The iron core is made of continuous high-quality oriented cold-rolled silicon steel strip from thin to thick, and then from thick to thin. The final cross-section is close to a circle, and the shape is an uncut closed rectangle, and then passes through a special R-shaped transformer The winding machine winds the coarse secondary on its PBT skeleton. Therefore, the transformer thus manufactured has no noise, low magnetic leakage, low no-load current, low iron loss, and high efficiency; and because the coil is cylindrical, the length of the coil copper wire wound by the R-type transformer winding machine short, so , Low internal resistance, low copper consumption, low temperature rise, low over-carrier motion, and better explosive force than toroidal transformers; in addition, the primary and secondary coils are separately wound with flame-retardant PBT engineering plastic skeletons, thus high electrical strength , Good flame retardancy.

        However, the manufacturing process is more complicated. The second is the winding of the coil. Because it is wound in a closed iron core, the PBT is composed of two parts, and then the R-type transformer winding machine drives the PBT skeleton to wind, and the winding accuracy is affected. A certain influence, one is the shape of its iron core, because its expanded shape is a spinning cone, so its mold and material utilization are relatively low.

        With the development of R-type transformer winding machines, the reduction of manufacturing costs, and the improvement of quality stability, R-type transformers are being favored by more and more electronics industries with their novel and unique structure and excellent electromagnetic performance. Especially suitable for medical equipment, display equipment, audio equipment, office equipment.

  Stable, high-speed and safe U-shaped core coil winding machine

The U-shaped coil winding machine is suitable for the winding of the bottom edge of the U-shaped core.Usually, the center of the U-shaped core is difficult to coincide with the rotation axis of the winding machine, resulting in a large vibration of the winding machine. , Affecting efficiency.

This type of winding machine developed by our company does not rotate the U-shaped iron core, only reciprocates, and rotates around the product to reduce vibration and improve efficiency.

      With the optimized clamping method, it only takes 2 seconds to complete the clamping.

      Therefore, the rotating parts of this type of machine have a large diameter and a high speed.There are similar machines on the market, and the larger ones do not have a protective cover. Safety accidents often occur.This machine of the company has a protective cover design.
