Description

Technical Field

[0001] The invention belongs to the technical field of transformer production, and in particular relates to a transformer coil winding damping device. Background Art

[0002] The coil is a key component of the transformer, and winding the coil is naturally an important task at the transformer production site. When winding the coil, the wire needs to have a certain tension during the entire winding process so that the wire can be tightly wound on the iron core. At this time, it is necessary to apply a certain damping device to the wire pay-off device during coil winding, so that the wire released from the wire pay-off end always has tension, which can further keep the wire wound on the iron core always taut, and then keep the coil tightly wound. Summary of the Invention

[0003] The present invention provides a transformer coil winding damping device to solve the problems in the above background technology.

[0004] The technical problem solved by the present invention is achieved by adopting the following technical solutions:

[0005] A transformer coil winding damping device includes a movable support, a fixed support, a wire coil and a damping part. The movable support and the fixed support are respectively located on both sides. The wire coil is installed between the movable support and the fixed support. The damping part is installed on the movable support to damp the rotation of the wire coil.

[0006] The movable support consists of a main support, a dovetail groove, a main roller, a nut, and a sliding bracket. The main support is fixed to the ground and features a dovetail groove on which the sliding bracket slides. The main roller is hingedly mounted on the sliding bracket. The main roller has a connecting boss at the end, on which a damping unit is mounted. The bottom of the sliding bracket features a dovetail slider that slides within the dovetail groove. The sliding bracket has an axial hole on which the main roller is hingedly mounted. The fixed support consists of a vertical plate and a follower roller. The vertical plate is supported on the ground to the side of the main support. The follower roller is hingedly mounted on the vertical plate. The follower roller cooperates with the main roller to support and mount the wire reel. The wire reel is the unwinding device for the wire during winding.

[0007] The damping part includes a damping wheel, a groove, a ball, a overlap block and a spring sheet. The damping wheel is fixedly mounted on the main roller shaft by a nut. The main roller shaft and the damping wheel roll synchronously. The damping wheel has a groove around its circumference, a ball on the side of the groove, and an overlap block on the side of the ball. The overlap block is fixedly mounted on the side of the sliding bracket. The overlap block squeezes the ball into the groove. A spring sheet is installed on the overlap block. The spring sheet extends upward and is located above the ball. The spring sheet squeezes the ball between the groove and the overlap block. In this way, the ball always has friction in the groove.

[0008] Furthermore, a nut mounts the damping portion on the end of the main roller.

[0009] Furthermore, the main roller is provided with a retaining spring groove, on which a retaining spring is installed to limit the main roller on the sliding bracket.

[0010] Furthermore, the front end of the main roller has a hexagonal head, which cooperates with a similar structure on the follower roller to install the wire coil on the entire device.

[0011] Furthermore, the end face of the nut is provided with 4-6 operating holes, and the nut is tightened or loosened through the operating holes with the aid of tools.

[0012] Furthermore, a clamping screw is installed on the side of the sliding bracket, and the clamping screw presses the sliding bracket to a suitable position of the main support.

[0013] Furthermore, both ends of the wire coil have hexagonal grooves, and the hexagonal grooves are installed through hexagonal heads.

[0014] Furthermore, the front end of the spring sheet has a downwardly bent pressing plate, which presses the ball.

[0015] The beneficial effects of the present invention are:

[0016] The present invention plays a damping role on a wire pay-out device when winding a transformer coil. The present invention has a round ball pressed in a groove. The round ball always has a damping effect on the rotation of the wire coil. The compression spring always presses the round ball in the groove. The device can keep the wire under tension when the coil is wound, thereby ensuring that the coil is wound tightly. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 1-Figure 3 The transformer coil winding damping device shown includes a movable support 10, a fixed support 20, a coil 30 and a damping part 40. The movable support 10 and the fixed support 20 are respectively located on both sides, the coil 30 is installed between the movable support 10 and the fixed support 20, and the damping part 40 is installed on the movable support 10 to damp the rotation of the coil 30.

[0023] The movable support 10 comprises a main support 11, a dovetail slot 12, a main roller 13, a nut 14, and a sliding bracket 15. The main support 11 is fixed to the ground and has a dovetail slot 12 on which the sliding bracket 15 is slidably mounted. The main roller 13 is hingedly connected to the sliding bracket 15. The nut 14 secures the damping unit 40 to the end of the main roller 13. The end of the main roller 13 has a connecting boss 131, on which the damping unit 40 is mounted. The main roller 13 also has a retaining spring slot 132, which holds a retaining spring to secure the main roller 13 to the sliding bracket 15. The front end of the main roller 13 has a hexagonal head 133, which cooperates with a similar structure on the follower roller 22 to secure the wire reel 30 to the entire device. The end face of the nut 14 has four to six operating holes 141, which are used to tighten or loosen the nut 14 using a tool. The sliding bracket 15 has a dovetail slider 151 at the bottom, which is slidably installed in the dovetail groove 12. The sliding bracket 15 has an axial hole 152, on which the main roller 13 is hingedly installed. A clamping screw 153 is installed on the side of the sliding bracket 15, which presses the sliding bracket 15 to a suitable position on the main support 11.

[0024] The fixed support 20 includes a vertical plate 21 and a follower roller 22. The vertical plate 21 is supported on the ground on the side of the main support 11. The follower roller 22 is hinged on the vertical plate 21. The follower roller 22 cooperates with the main roller 13 to support and install the wire reel 30.

[0025] The wire coil 30 is a wire unwinding device when the wire is wound. Both ends of the wire coil 30 have hexagonal slots 31, and the hexagonal slots 31 are installed through a hexagonal head 133.

[0026] The damping part 40 includes a damping wheel 41, a groove 42, a ball 43, a bridge block 44 and a spring sheet 45. The damping wheel 41 is fixedly mounted on the main roller shaft 13 by a nut 14. The main roller shaft 13 rolls synchronously with the damping wheel 41. The damping wheel 41 has a groove 42 around it, and a ball 43 is provided on the side of the groove 42. A bridge block 44 is provided on the side of the ball 43. The bridge block 44 is fixedly mounted on the side of the sliding bracket 15. The bridge block 44 squeezes the ball 43 into the groove 42. A spring sheet 45 is installed on the bridge block 44. The spring sheet 45 extends upward and is located above the ball 43. The spring sheet 45 squeezes the ball 43 between the groove 42 and the bridge block 44. In this way, the ball 43 always has friction in the groove 42. The front end of the spring sheet 45 has a downwardly bent pressure plate 451, and the pressure plate 451 presses the ball 43.

[0027] The working principle of the present invention is as follows: the ball 43 is compressed between the spring sheet 45, the groove 42, and the bridge block 44, and constantly exerts friction on the groove 42. The compression screw 153 is loosened, the sliding bracket 15 is moved, and the wire reel 30 is installed between the main roller 13 and the follower roller 22. Because the wire reel 30 is a pay-off device, it does not require a power source. When the wire is pulled outward, the friction of the ball 43 on the groove 42 acts as a damping force on the pay-off rotation of the wire reel 30 through the damping wheel 41 and the main roller 13. Throughout the pay-off process, tension is always applied to the wire.

[0028] The above embodiments primarily illustrate the transformer coil winding damping device of the present invention.
