目前我国紧固标准件产量较大、出口量激增,但模具供应的数量、质量和规格尚不能满足生产要求。在标准件生产中,模具的成本约占生产成本的12％,比国外高出1倍左右。 我厂根据自制各种牌号高质量硬质合金,金刚石砂轮以及机加工装备的优势,研制成功硬质合金冷镦六角螺母凹模,六片组合硬质合金冷、热镦六角螺母凹模,以及硬质合金六角螺母勒光模具,其中包括尚未制订国 At present, China fastens a larger production of standard parts and exports surge, but the quantity, quality and specifications of the molds are still not enough to meet the production requirements. In the standard parts production, mold costs account for about 12% of production costs, about 1 times higher than abroad. I plant under the various brands made of high-quality carbide, diamond grinding wheel and the advantages of machining equipment, the successful development of hard alloy cold heading hexagonal nut die, six combinations of carbide cold, hot upsetting hex nut die, and Carbide hexagonal nut light mold, including not yet developed countries
