| titleOfInvention | Intermediate frequency heating device for copper joint of red punch pressure gauge |
| abstract | The utility model relates to an intermediate frequency heating device for copper joints of pressure gauges with red punching method, which belongs to the technical field of processing copper joints of pressure gauges. It includes a blank conveying pallet, on which a transparent insulating tube is arranged along the length direction of the blank conveying pallet, and hollow electric heating metal windings are wound on the outside of the transparent insulating pipe, and each hollow electric heating metal winding is connected to a frequency conversion box, the frequency conversion box is connected to the controller. The utility model has the following beneficial effects: the inside and outside of the billet are heated evenly, the softening degree of the billet is consistent, the density of the product after red punching is balanced and consistent, and the inner "hard block" and density inconsistency are prevented; Running at a constant speed inside the tube greatly reduces the metal oxidation on the surface of the billet, and reduces the quality of the scale being sandwiched into the billet during the stamping process; no pollution, no waste gas generation; energy saving, low power consumption, saving 20% after energy conversion; quality Improvement, uniform density, reduce waste products; reduce labor intensity, improve efficiency. |
