Vertical hollow coil forming device

Abstract

The invention discloses a vertical hollow coil forming device. The vertical hollow coil forming device is characterized by comprising a lower die and an upper die, wherein a coil positioning core is arranged on the lower die, a vertical hollow coil can be arranged on the coil positioning core in a sleeved manner, the upper die comprises a coil long pin forming cutter block, a die handle, a coil short pin forming cutter block and an upper bottom plate, the coil long pin forming cutter block and the coil short pin forming cutter block are arranged on a first surface of the upper bottom plate atan angle, the die handle is arranged on the second surface of the upper bottom plate, a first groove is formed in the coil long pin forming cutter block, a second groove is formed in the coil short pin forming cutter block, and the first groove and the second groove are positioned at different heights, respectively corresponding to a first pin and a second pin of the vertical hollow coil which areclamped and sleeved on the coil positioning core. According to the vertical hollow coil forming device, the production efficiency and the product qualification rate of the vertical hollow coil are improved, the risk of short circuit of the coil insulation layer is reduced, and meanwhile, the equipment and the mold cost required for producing the vertical hollow coil are reduced.

Description

technical field [0001] The invention relates to the technical field of manufacturing hollow coils and vertical coil forming molds, in particular to a vertical hollow coil forming device with a large wire diameter. Background technique [0002] At present, in the electronics industry, although many inductance coils are packaged by SMD, the vertical plug-in method is more reliable and reasonable for high-power inductance coils widely used in the frequency conversion field. At present, there is still a great demand for air-core coils for vertical plug-ins, but there are still some problems and shortcomings in manufacturing technology to produce these high-power coils: [0003] 1) High-power vertical coils are made of large-diameter electromagnetic wires. To make these vertical hollow coils with large diameters, the production machines must have high-power power, and such machines are expensive; The long-term production of such coils has a great impact on the wear and life of t...

AI Technical Summary

Problems solved by technology

[0003] 1) High-power vertical coils are made of large-diameter electromagnetic wires. To make these vertical hollow coils with large diameters, the production machines must have high-power power, and such machines are expensive; Long-term production of such coils has a great impact on the wear and life of the equipment, resulting in increased production costs

[0004] 2) The diameter of the vertical hollow coil wire is large, and it needs a lot of force to push the electromagnetic wire before it can be formed. It is easy to scratch the insulation layer of the electromagnetic wire, resulting in short circuit and oxidation of the coil. The mold formed by the machine is difficult to produce. To have high precision and smoothness, the cost of the mold is much higher than that of ordinary molds, and it is inconvenient to maintain and debug

[0005] Due to the large wire diameter of the coil, there are many inconsistencies in the distance between the pins after molding, which will affect the later PCB assembly and use. It is often necessary to add pins and repeat the calibration process, resulting in high production costs and low efficiency.
