Description

Technical Field

[0001] The utility model relates to the technical field of transformer core production, in particular to a winding device for transformer core production. Background Art

[0002] The transformer core is an important component of the transformer, usually made of materials such as silicon steel sheets or Permalloy. The function of the transformer core is to provide a high magnetic permeability path so that the magnetic field generated by the current in the transformer can be more concentrated and effectively transmitted. The higher the magnetic permeability of the transformer core, the better the performance of the transformer. Generally speaking, the closer the shape of the transformer core is to a circle, the higher its magnetic permeability.

[0003] As disclosed in Chinese patent: A winding device, application number: 202222831556.8, includes a fixed frame, a winding roller, a reciprocating screw rod, a driving assembly, a dust suction assembly and a monitoring assembly, both sides of the inner wall of the fixed frame are rotatably connected with connecting parts, the winding roller is detachably connected with the two connecting parts, the two sides of the inner wall of the fixed frame are rotatably connected with the reciprocating screw rod, the outside of the fixed frame is provided with a driving assembly, and the external thread of the reciprocating screw rod is connected with a slider. The utility model drives the winding roller and the reciprocating screw rod to rotate through the driving assembly, which can not only wind the yarn, but also arrange the wire, so as to ensure the neat effect of the yarn winding, the dust and thread ends on the yarn can be processed through the dust suction assembly, and the yarn can be kept clean, the yarn on the winding roller can be detected through the monitoring assembly, and when the yarn is wrapped around the entire winding roller, it can send a signal to remind the staff, so as to facilitate the staff to replace the winding roller in time.

[0004] However, in the above technical solution, the transformer core is usually made of materials such as silicon steel sheets or Permalloy, which results in the transformer core rebounding when the transformer core is wound by a winding device, and as the winding thickness of the transformer core increases, the rebound force gradually increases, which causes the transformer core to become loose, affecting subsequent production and processing.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 and Figure 2 As shown, a winding device for transformer core production includes a device body 1, a rotating disk 2 is provided on the device body 1, two telescopic push plates 3 are provided on the rotating disk 2, two slide grooves 4 are provided between the two telescopic push plates 3, a slider 5 is slidably provided in the slide groove 4, a pressure plate 6 is provided on the slider 5, a groove 7 and an auxiliary correction mechanism 8 are provided on the pressure plate 6, a spring 9 is fixedly provided on the outer wall of one side where the two sliders 5 are close to each other, and a winding column 10 is provided between the two pressure plates 6.

[0024] like Figure 3 and Figure 4 As shown, in another embodiment of the utility model, the auxiliary correction mechanism 8 is provided with a lifting block 801 in the groove 7, and the lifting block 801 is provided with a threaded hole 802 and a plurality of guide slots 803, and a guide slider 804 is provided in the guide slot 803, and a rotating threaded column 805 is provided in the threaded hole 802, and a knob 806 is provided at one end of the rotating threaded column 805;

[0025] The lifting block 801 is provided with a hydraulic telescopic column 807 on one side close to the winding column 10, and the end of the hydraulic telescopic column 807 away from the lifting block 801 is provided with a sensor 808. When it is necessary to perform auxiliary correction on both sides of the transformer core during the winding process, the knob 806 is first turned, and the knob 806 drives the rotating threaded column 805 to rotate. The rotating threaded column 805 moves the lifting block 801 upward or downward through the threaded hole 802, and the lifting block 801 drives the hydraulic telescopic column 807 to move, and then the position of the hydraulic telescopic column 807 is moved accordingly according to the winding width of the transformer core. The hydraulic telescopic column 807 can fit the outer wall surfaces on both sides of the transformer core, and then the hydraulic telescopic column 807 is started, and the hydraulic telescopic column 807 is used to move the sensor 808 to the winding column 10, so that the sensor 808 fits the winding column 10, and then the transformer core can be wound. During the winding process, the hydraulic telescopic column 807 is used to assist in correcting the two sides of the transformer core. At the same time, since the hydraulic telescopic column 807 is rotatably connected to the lifting block 801, the friction between the transformer core and the hydraulic telescopic column 807 during the winding process can be effectively reduced, thereby preventing damage to the two sides of the transformer core due to excessive friction.

[0026] The working principle of a winding device for transformer core production:

[0027] When in use, first connect one end of the transformer core to the winding column 10, then turn the knob 806, the knob 806 drives the rotating threaded column 805 to rotate, the rotating threaded column 805 moves the lifting block 801 upward or downward through the threaded hole 802, the lifting block 801 drives the hydraulic telescopic column 807 to move, and then according to the winding width of the transformer core, the position of the hydraulic telescopic column 807 is moved accordingly, so that the hydraulic telescopic column 807 can fit the outer wall surface of both sides of the transformer core, and then the hydraulic telescopic column 807 is started, and the hydraulic telescopic column 807 is used to move the sensor 808 to the winding column 10, so that the sensor 808 fits the winding column 10, and then the rotating disk 2 can be started to move the transformer The core is wound, and during the winding process, the two sides of the transformer core are supplemented by the hydraulic telescopic column 807. As the transformer core is wound, the transformer core gradually becomes thicker. At this time, the gradually thickening transformer core will fit with the arc-shaped outer wall of the pressure plate 6. The pressure plate 6 is used to squeeze the transformer core to prevent the transformer core from being too loose. As the transformer core gradually becomes thicker, the pressure plate 6 will also gradually move, and the pressure plate 6 drives the slider 5 to move, and the spring 9 gradually extends. The thicker the transformer core, the higher the deformation of the spring 9, and the higher the squeezing force of the pressure plate 6 on the transformer core. Therefore, the transformer core can be effectively squeezed according to the thickness of the transformer core, effectively preventing the transformer core from being too loose.

[0028] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
