山东beplay全站app安卓的热加工质量对beplay全站app安卓的性能与使用寿命影响甚大。在实际生活工作中我们beplay全站app安卓车间对各种beplay全站app安卓的设计及生产都要求精益求精,而具体操作还会出现问题,下面一起来跟随beplay全站app安卓厂小编一起来讨论交流一下冲压beplay全站app安卓使用中的问题:
The hot working quality of Shandong mould has a great influence on its performance and service life. In our daily life, our mold workshop requires continuous improvement in the design and production of various molds, and there will be problems in the specific operation. Let's follow the small editor of the mold factory to discuss and exchange the problems in the use of stamping molds
(1)锻造工艺,这是beplay全站app安卓工作零件制造过程中的重要环节。对于高合金工具钢的beplay全站app安卓,通常对材料碳化物分布等金相组织提出技术要求。此外,还应严格控制锻造温度范围,制定正确的加热规范,采用正确的锻造力法,以及锻后缓冷或及时退火等。
(1) Forging process, which is an important link in the manufacturing process of die working parts. For the mould of high alloy tool steel, the technical requirements for the metallographic structure such as carbide distribution are usually put forward. In addition, the forging temperature range should be strictly controlled, the correct heating specification should be formulated, the correct forging force method should be adopted, and the slow cooling or timely annealing after forging should be adopted.
(2)预备热处理。应视beplay全站app安卓工作零件的材料和要求的不同分别采用退火、正火或调质等预备热处理工艺,以改善组织,消除锻造毛坯的组织缺陷,改善加工工艺性。高碳合金beplay全站app安卓钢经过适当的预备热处理可消除网状二次渗碳体或链状碳化物,使碳化物球化、细化,促进碳化物分布均匀性。这样有利于保证淬火、回火质量,提高beplay全站app安卓寿命。
(2) Prepare for heat treatment. According to the different materials and requirements of die working parts, the pre heat treatment processes such as annealing, normalizing or quenching and tempering should be adopted to improve the microstructure, eliminate the microstructure defects of forging blank and improve the processing technology. After proper preparation heat treatment, the network secondary cementite or chain carbide can be eliminated, the carbide can be spheroidized and refined, and the distribution uniformity of carbide can be promoted. In this way, the quenching and tempering quality can be guaranteed and the service life of the die can be improved.

(3)淬火与回火。这是beplay全站app安卓热处理中的关键环节。若淬火加热时产生过热,不仅会使工件造成较大的脆性,而且在冷却时容易引起变形和开裂,严重影响beplay全站app安卓寿命。冲模淬火加热时特别应注意防止氧化和脱碳,应严格控制热处理工艺规范,在条件允许的情况下,可采用真空热处理。淬火后应及时回火,并根据技术要求采用不同的回火工艺。
(3) Quenching and tempering. This is the key link in the heat treatment of mould. If overheating occurs during quenching and heating, the workpiece will not only cause greater brittleness, but also easily cause deformation and cracking during cooling, which will seriously affect the service life of the die. During quenching and heating of die, special attention should be paid to prevent oxidation and decarburization. The heat treatment process specification should be strictly controlled. If conditions permit, vacuum heat treatment can be used. After quenching, it should be tempered in time, and different tempering processes should be adopted according to the technical requirements.
(4)消应力退火。beplay全站app安卓工作零件在粗加工后应进行消应力退火处理,具目的是消除粗加工所造成的内应力,以免淬火叫产生过大的变形和裂纹。对于精度要求高的beplay全站app安卓,在磨削或电加工后还需经过消应力回火处理,有利于稳定beplay全站app安卓精度,提高使用寿命。
(4) Stress relief annealing. Die working parts should be treated with stress relief annealing after rough machining to eliminate the internal stress caused by rough machining, so as to avoid excessive deformation and cracks caused by quenching. For the mold with high precision, stress relief tempering treatment is needed after grinding or electrical machining, which is conducive to stabilizing the mold precision and improving the service life.
