    Precision winding machine

       Precision winding machine For general winding machines, including CNC and automatic winding machines, only the set number of turns of enameled wire is required to be wound, and the appearance is roughly flat, but there are some special high-demand occasions , It is required that the arrangement of enameled wires must be neat without a random winding.

          

       This kind of coil has several advantages. First, the consistency of inductance is very high. Second, the enameled wire occupies less space, and the enameled wire can reach the ideal neat arrangement. Third, the energy density is high. Fourth, the high temperature resistance performance is better. , The enameled wires are in line contact, and in the case of random winding, the superimposition between the wires will have a little contact, and it is easy to break down under high temperature and high pressure.

                   

       The coil in this case video has an enameled wire diameter of 0.8mm and a total number of turns of 3250 turns. The inside of the coil is round, the winding is stable and easy to operate, and the enameled wire is arranged in 50 layers. There is a large redundant space for the customer's research and development needs.

   At present, the precision coil winding machines on the market are mainly arranged neatly between 10-30 layers, and the technology is mainly mastered by Japanese and European and American winding machine manufacturers represented by Marsilli, Odawara and Nittoku.

   At present, there is a huge coil market in my country, but most of them are subject to the constraints of high-precision winding machines, and only medium and low-end coils are processed. The processing accuracy is not high and the added value is low. However, the development of domestic precision winding machines is far from enough. industry demand.

   After years of technical precipitation, numerous tests and unremitting efforts, REPOSAL® winding machine has finally moved the precision winding machine from the experimental stage into the production stage. The situation that domestic precision coil winding is controlled by precision winding machine is alleviated, so that more production and R&D units are no longer troubled by this.

   We have been adhering to the mission - to win the trust and support of customers and consolidate the brand value of products by providing customers with more competitive solutions and equipment.

       Below we introduce the structure of this toroidal coil winding machine. This part is the controller and this part is the clamping base. We control the product clamping by opening and closing the handle. This position is the storage ring. The enameled wire is stored on the storage ring first, and then wound around this product. This position is a manual winding handle. Turn this handle. The steel plate can be driven manually. The steel ring has an opening. This position is an opening. The opening is opened and closed by sliding the handle up and sliding to the left. . This position is called the crimping plate, and this position is called the baffle. After the line is removed, its degree of tightness is determined by the tension of the belt. The tension of the belt is adjusted by the tension adjustment knob. When adjusting the tension of the belt, first loosen this And then rotate the handle. When rotating the handle, there is an idler wheel. When the idler wheel goes in, the tension of the belt will increase, so that the winding of the enameled wire will become tighter.

Enameled wire production process

Enameled wire production process

Enameled wire technological process: pay-off→anneal→paint→baking→cooling→take-up

1. Pay-off On a normally operating enameled machine, most of the operator's energy and physical strength are consumed in the pay-off part. The replacement of the pay-off reel makes the operator pay a lot of labor, and the joints are prone to quality problems when changing the line. An operating failure has occurred. An effective method is to pay off with large capacity.

     The key to pay off is to control the tension. When the tension is large, it will not only draw the conductor thin, make the surface of the wire lose its brightness, but also affect many properties of the enameled wire. From the appearance point of view, the enameled wire that is drawn thinner has poor gloss; from the performance point of view, the elongation, resilience, flexibility, and thermal shock of the enameled wire are all affected. If the pay-off tension is too small, the line will easily jump and cause the line to be merged and the line to touch the furnace mouth. When paying off, the most fear is that the half-turn tension is high and the half-turn tension is small. This will not only cause the wires to loosen, break, and be thinned section by section, but also cause large jumps of the wires in the oven, resulting in failures of merging and touching the wires. Pay-off tension should be even and appropriate.

     Installing a booster wheel in front of the annealing furnace is very helpful for tension control. The maximum non-extension tension of soft copper wire at room temperature is about 15kg/mm2, the maximum non-extension tension at 400℃ is about 7kg/mm2; the maximum non-extension tension at 460℃ is 4kg/mm2; the maximum non-extension tension at 500℃ The extension tension is 2kg/mm2. In the normal enameled wire coating process, the tension of the enameled wire is significantly less than the non-extension tension, which is required to be controlled at about 50%, and the pay-off tension should be controlled at about 20% of the non-extension tension.

             REPOSAL®  Winding Machine successfully overcomes the difficulty in the winding process of closed coils of fixed-length titanium plates with loops.

      These tiny looped titanium plates are shown here, small metal structures approximately 12mm long, 4mm wide and 1.5mm thick, and have a row of four circular holes through them, two of which are for The main body pulls the suture through, and the other two upper holes are used for the passage of another group of seam lines. The structure is small in size, and it is necessary to form a closed connecting loop through the structural member, and the closed connecting loop is formed by twisting the yarn fibers of the loose structure. A closed high-strength braided coil is passed through the middle, which seems simple, but its core technology is reflected in the Loop, that is, a high-strength coil, which is woven evenly, tightly, non-woven, and without joints.


        This kind of titanium plate with loops is divided into two types, fixed-length type and adjustable type, especially the fixed-length type, whose length ranges from 15mm to 60mm. It is necessary to wind this closed loop in the middle of a titanium plate with such a small volume. Coils, and because the number of colonies cannot exceed the standard, cannot be wound by hand, but must be wound by 

equipment, which is extremely difficult to process. Its structural parts are small in size, and the diameter of the holes is only 1-1.5mm. It needs to form twisted yarns under such conditions, so this product has always been processed manually by hand, and its efficiency is low and consistent. Sex is hard to guarantee.

            

Because of the small size of the structure, the diameter of the hole is only 1-1.5mm, and it needs to form twisted yarn under this condition, so this product has been processed manually, and its efficiency is low. Consistency is difficult to guarantee.

   REPOSAL® Winding Machine successfully developed this equipment according to the customer's request, completed the simultaneous formation of a closed loop (including fiber bundles with a loose structure) and passed it to the porous structural parts, and maintained the twisted structure, which greatly improved the closed loop. The winding efficiency, in addition to obtaining the incomparable consistency of pure hand-made, makes the product have the conditions for large-scale production.
