Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electromagnetic thermal crack arrest technology, and specifically relates to an electromagnetic thermal crack arrest structure for a metal mold device. Background Technology
[0002] Metal molds, made of metal materials, are used in the mass production of workpieces. During use, various factors can cause cracks in these molds. These cracks gradually increase in depth, potentially reducing the mold's precision and rendering it unusable. Electromagnetic thermal crack arrest technology is based on the effects of current concentration and thermo-mechanical coupling. When a pulsed current passes through a cracked metal mold, the crack tip experiences instantaneous high temperatures due to the highly concentrated current density. This melts the metal at the crack tip, forming a localized weld. Subsequently, during ultra-rapid cooling, the crack tip region undergoes impact hardening, forming ultra-fine cryptocrystalline martensite and fine-grained carbides, resulting in a strengthened structure. However, during crack arrest repair of metal molds, external forces can interfere with the metal equipment, leading to misalignment due to the mold's lack of fixation. This can cause the electrodes electrically connected to the mold to fall off, posing a safety hazard due to the current generated at the electrodes. Furthermore, rapid cooling is required after current repair; insufficient cooling can result in poor impact hardening, leading to substandard crack repair quality.
[0003] In summary, the lack of fixation and rapid cooling of the metal mold for electromagnetic thermal crack arrest repair presents several problems during use. Therefore, it is hoped that a new structure can be proposed to solve the aforementioned technical issues. Utility Model Content
