Description

Technical Field

[0001] This application relates to the field of edge pressing technology, specifically to a transformer belt double-cone edge pressing device. Background Technology

[0002] The standard for transformer copper strips addresses edge burrs in two ways: right-angle and rounded. Right-angle edges are affected by factors such as product thickness tolerance fluctuations, plate shape, performance uniformity, and shearing quality, making it difficult to completely eliminate burrs. Rounded edges are processed more slowly and are not easily mass-produced.

[0003] Currently, traditional processing methods, such as small flat roller bearings and small tapered roller bearings, result in insufficient longitudinal pressure and incomplete removal of burrs along the groove edges. Utility Model Content

[0004] The purpose of this application is to provide a transformer belt double-conical edge pressing device, which solves the problem of insufficient longitudinal pressure and incomplete removal of burrs on the groove edge in the traditional processing methods proposed in the background art: small flat roller bearings and small conical roller bearings.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This application provides a transformer with a double-conical edge pressing device, including two sets of brackets. Four sets of rollers are respectively arranged on one side of each set of brackets. A first ball bearing is installed on the outer wall of each set of rollers.

[0016] Optionally, a pin is embedded in the inner wall of each group of the second ball bearings, and a pressure cap is installed on one side of the pin. One of the pins in each group passes through the slider, and the other pin in each group rotates through the first fixing plate. A hexagonal nut is threaded to the side of the pin away from the pressure cap, and a flat washer is fitted on the outer wall of the pin located inside the hexagonal nut.

[0032] In the technical solution of this application, by adopting a vertical moving mechanism to press down, selecting a large-size second ball bearing C8, and optimizing the pressing edge angle and curvature, a double conical edge is achieved, and the edges of the copper strip no longer contact the insulation layer, eliminating puncture and breakdown accidents. This successfully avoids the problem of breakdown and short circuit scrapping when the transformer strip is wound, greatly reducing the amount of rework and repair for manufacturers and customers, and effectively improving the manufacturing qualification rate of transformer products.

[0033] In the technical solution of this application, such as Figures 1-3 As shown, the guiding and moving mechanism includes two sets of linear guide rails C7 fixedly installed on the upper end of the bracket 1. Each set of linear guide rails C7 has four sets of second mounting plates 10 slidably installed on the upper end of each set of linear guide rails C7. The bracket 1 can fix the linear guide rails C7, while the first guide rail can guide the second mounting plates 10 to move.

[0034] In the technical solution of this application, such as Figure 3 As shown, the connecting mechanism includes four sets of first mounting plates 9 fixedly installed on the upper end of the second mounting plate 10 by first hexagonal socket bolts C3. The first mounting plates 9 are arranged in a Z-shape, and the second mounting plate 10 can be installed on the top of the first mounting plate 9 by the first hexagonal socket bolts C3.

[0035] In the technical solution of this application, such as Figure 3 As shown, the spacer 3 abuts against the first mounting plate 9, and the roller A1 is installed and inserted into the inner wall of the first mounting plate 9. The first mounting plate 9 can be used to install and position the roller.

[0036] In the technical solution of this application, such as Figure 1 As shown, an adjusting rod 8 is rotatably inserted into the inner wall of each of the four groups of first mounting plates 9. Nuts are threaded onto the outer walls of the adjusting rods 8 located on both sides of each group of first mounting plates 9. The adjusting rods 8 can further connect each first mounting plate 9, and the nuts can adjust the spacing between each first mounting plate 9.

[0037] In the technical solution of this application, such as Figures 1-4 As shown, the vertical movement mechanism includes four sets of pressure plates 4 fixedly mounted on the upper end of the first mounting plate 9 by second hexagonal socket head cap screws C4. A rotating shaft 5 is threaded onto the inner wall of the pressure plate 4. A slider 6 is fixedly mounted on the lower end of the rotating shaft 5. The inner wall of the slider 6 is slidably connected to the inner wall of the first mounting plate 9. The pressure plates 4 connect the rotating shaft 5 and the first mounting plate 9.

The operator rotates the wave-shaped handwheel C2, causing the rotating shaft 5 to rotate. The slider 6 at the lower end of the rotating shaft 5 slides along the inner wall of the first mounting plate 9, moving vertically downwards to apply pressure to the copper strip. During the pressing process, the large-sized second ball bearing C8, combined with the optimized edge pressing angle and curvature, extrudes the edge of the copper strip, forming a double-conical edge structure. If the processing effect needs to be adjusted, the distance between the first mounting plates 9 can be changed by adjusting the connecting rod 8 and the nut to accommodate the processing requirements of copper strips of different specifications. After processing, the wave-shaped handwheel C2 is stopped, the processed copper strip is removed, and subsequent production processes are carried out.
