Description

Technical Field

[0001] The invention relates to the technical field of triangular three-dimensional iron core winding, and in particular to a triangular three-dimensional wound iron core high- and low-voltage coil integrated winding machine. Background Art

[0002] The shape of the triangular three-dimensional wound core is composed of three equilateral triangle core columns arranged in three dimensions. It has a reasonable structure, tight winding, no air gap in the magnetic circuit, the three magnetic circuits are of the same length and the shortest, and the cross-sectional area of ​​the core columns is close to a circle. Therefore, the performance is further improved, and it has the advantages of low loss, low noise, and three-way balance. It is widely used in equipment such as transformers and reactors.

[0003] There are two types of triangular three-dimensional wound cores: silicon steel three-dimensional wound cores and amorphous three-dimensional wound cores. The main difference between the two types of wound cores lies in the material of the core column. During the production process of the wound core, the joint parts of the three core columns need to be wound with coils. During the winding operation, the low-voltage coil is wound first, and then the high-voltage coil is wound.

[0004] At present, conventional winding equipment can only fully automatically produce one model and one type of triangular three-dimensional wound core. The main reason is that the degree of automation of the equipment is relatively low. During the production process, the clamping, winding and wiring devices cannot be accurately adjusted, which makes the adaptation range of the entire equipment small and is not conducive to full-type production.

[0005] In order to ensure that the automated equipment can produce different models and types of triangular three-dimensional wound cores according to factory needs, the entire equipment needs to be modified. Summary of the invention

The motor of the clamping seat driving motor 87 rotates, and the clamping seat driving motor 87 drives the clamping seat driving screw 90 to rotate. The rotation of the clamping seat driving screw 90 causes the clamping seat 88 to open synchronously, and then the triangular three-dimensional wound core is loaded into the clamping seat 88 through the lifting equipment, and then the clamping seat driving screw 90 is rotated so that the clamping seat 88 can be close to the two ends of the triangular three-dimensional wound core, and then the three-claw clamping plate 89 clamps the two ends of the triangular three-dimensional wound core.

During the winding process, the wire will gradually translate along the winding surface. When the winding part moves to the other end position, the foil winding motor 73 is stopped. After that, the worker needs to move the wire to the starting end and then start the foil winding motor 73 again. After completion, the low-voltage coil is wound again.

When the high-voltage coil is wound, the high-voltage wire bracket drives the motor 59 to rotate and drive the transverse transmission screw 61. The transverse transmission screw 61 drives the wire guide frame 62 to move horizontally, so that a high-voltage coil is formed on the surface of the low-voltage coil.

[0093] After the high-voltage coil is formed, the entire winding tooling is removed, and then the coil winding of the second station is carried out, and the output motor 91 is started.

After the winding is completed, the completed core is removed, and a new core is installed for the next winding.

After completion, the butted ends are passed through the longitudinal foil guide roller 26 and between the lower pressure rod 25 and the foil support rack 24, and are directly introduced into the winding fixture. Then, the foil winding motor 73 is started, and the foil winding motor 73 drives the foil winding motor support 72. The foil winding motor support 72 drives the drive shaft 76 to rotate, and the drive shaft 76 drives the conduction wheel 77. The conduction wheel 77 drives the winding fixture to rotate. The winding fixture rotates so that the foil is wound on the winding fixture. After the low-voltage coil winding is completed, the foil winding motor 73 is stopped.

[0097] Put the end of the foil into the foil support rod 43, then introduce the free end of the high-voltage wire on the high-voltage coil wire rack 18 to the top of the foil support rod 43, then start the two positioning cylinder mounting seats 33, the main shafts of the two positioning cylinder mounting seats 33 extend, so that the center of gravity of the two positioning cylinder mounting seats 33 moves forward, and the two positioning cylinder mounting seats 33 rotate around the positioning cylinder mounting seats 33.

The output motor 91 controls the three-claw clamping disk 89 to rotate, thereby making the triangular three-dimensional winding core the second winding station, and then repeat the original operation steps until the three coils are wound.
