Drawing the industry some of the foreign manufacturers to introduce advanced technology, such as advanced operating line and drawing equipment, and its benefits to be normal play, must meet with the technology, high-speed wire drawing machine can guarantee the normal operation, One high-speed wire drawing machine so that some Drawing Die is one of them.
Drawing Die wire drawing production is the key tool that directly affect the quality of the steel quality, mold losses, the production of energy consumption and economic benefits. Die pore structure and size of ministries is the key to mold quality parameters, particularly the high-speed wire drawing machine, the structure does not pass with the design requirements, would seriously affect the life of mold and drawing machine drawing speed. This requires grinding die in the process of production, the operator must make the best of these parameters in order to make the necessary amendments to improve product quality.
At present, China's manufacturing Drawing Die level of advanced countries in the world and a greater gap, one of which is pass design level, and the second is grinding production levels, both of which compare the original First of all, because of grinding equipment behind, most manufacturers use manual , With workers operating experience and personal skills to operate small-scale production mode, can not achieve the desired results, therefore, can not meet the needs of high-speed production. Secondly, because of grinding process can not guarantee that pass ministries parameter, so even if the pass was re-design a reasonable, there is no way to ensure its accuracy, even more serious in China in recent decades is not a sophisticated detection die Pass Means no more talk about whether it is pass-size design requirements for transformation process.
Now, most manufacturers only for visual observation with the naked eye, can not pass their ministries signed the precise size, some foreign advanced countries such as Japan the use of plastic liquid plastic cast to die casting hole, after the removal of solidified in the next projector Measured from the site size, the United States after the dissolution of the use of rubber-Die Casting, solidification, the projector is also under the measure site size, slow precision of this method worse, not adapting a large-scale production requirements. Accordingly, we plan to develop a model based on the Singlechip drawing pass quickly measuring instrument, the aircraft can quickly and accurately to facilitate the visually read Drawing Die hole size of ministries to meet the fabricated metal products industry Drawing Die on the design, manufacture Testing needs. Drawing Die industry to improve the design and manufacture of drawing-level play a positive role in promoting and enhancing the Drawing Machine Drawing speed and production efficiency is important.
based on the design. NET-Drawing Die diameter measurement system parameters computer software system, mainly to complete survey data analysis and processing module, the measurement data dynamic graphic display module and graphics data storage, query module, statements related to the formation of production and printing module
304 硬度HRB在90左右，容易变形 耐腐蚀性较好，
工具钢 比较合适
T7、T7A 亚共析钢。具有较好的塑性、韧性和强度，以及一定的硬度，能承受震动和冲击负荷，但切削能力差。用于制造承受冲击负荷不大，且要求具有适当硬度和耐磨性，及较好的韧性的工具，如锻模、凿子、锤、冲头、金属剪切刀、扩孔钻、钢印、木工工具、风动工具、机床顶尖、钳工工具、钻凿工具、较钝的外科医疗用具等。
T8、T8A 共析钢。淬火加热时容易过热，变形也大，塑性和强度比较低，不宜制造承受较大冲击的工具，但经热处理后有较高的硬度和耐磨性。用于制造切削刃口在工作时不变热的工具，如木工工具、风动工具、钳工工具、简单模具、铆钉冲模、中心孔铳和冲模、切削钢材用工具、轴承、刀具、铝锡合金压铸板和型芯，以及各类弹簧等。
T8Mn、T8MnA 共析钢。具有较高的淬透性和硬度，但塑性和强度较低。用于制造断面较大的木工工具、手锯锯条、刻印工具、铆钉冲模、发条、带锯锯条、圆盘锯片、煤矿用凿、石工用凿等。
T9、T9A过共析钢。具有较高的硬度，但塑性和强度较低。用于制造要求较高硬度且有一定韧性的各种工具，如刻印工具、铆钉冲模、压床模、冲头、木工工具、农机切割零件、凿岩工具和铸模的分流钉等。
T10、T10A过共析钢。晶粒细，在淬火加热时（温度达800℃）不致过热，仍能保持细品粒组织；淬火后钢中有未溶的过剩碳化物，所以具有比T8、T8A钢更高的耐磨性，但韧性较低。
用于制造切削刃口在工作时不变热的工具，不承受冲击负荷而具有锋利刃口和少许韧性的工具，如加工木材用工具、手用横锯、手用细木工具、机用细木工具、麻花钻、拉丝模、冲模、冷镦模、螺丝锥、扩孔刀具、搓丝板、车刀、刨刀、铣刀、货币压模、小尺寸断面均匀的冷切边及冲孔模、低精度形状简单的卡板、钳工刮刀、硬岩石钻子、制铆钉和钉子用工具、螺丝刀、锉刀、刻纹用凿子、切纸和烟叶用刀具等。
工具钢
T11、T11A 过共析钢。具有较好的综合力学性能（如硬度、耐磨性和韧性等），晶粒更细，在加热时对晶粒长大和形成碳化物网的敏感性小。用于制造在工作时切削刃口不变热的工具，如锯、錾刀、丝锥、锉刀、刮刀、发条、仪规、扩孔钻、板牙、切烟叶用刀具、尺寸不大和断面无急剧变化的冷冲模及木工刀具等。 T12、T12A 过共析钢。由于碳含量高。淬火后仍有较多的过剩碳化物，所以硬度和耐磨性高，但韧性低，且淬火变形大。不适于制造切削速度高和受冲击负荷的工具。用于制造不受冲击负荷，切削速度不高，切削刃口不变热的工具，如车刀、铣刀、钻头、铰刀、扩孔钻、丝锥、板牙、刮刀、量规、刀片、小型冲头、钢锉、锯、发条、切烟叶用刀具，及断面尺寸小的冷切边模和冲口模等。
用于制造不受冲击负荷，但要求极高硬度的金属切削工具，如剃刀、刮刀、拉丝工具、锉刀、刻纹用工具、钻子，以及坚硬岩石加工用工具和雕刻用工具等。
