This article mainly introduces the influence of Jiangsu NSK bearing on the metal structure and performance of forgings as well as the defects of forgings, the content and method of the quality inspection of forgings, and the general process of the quality analysis of forgings.
抛头由变频电机间接驱动。改变电机的频率后,可将投掷头的旋转速度转换为江苏NSK轴承。在向心力的作用下,钢球从叶轮轴线的孔上飞溅到叶片上,然后用高速旋转叶片将叶片甩出立体角。叶轮的转速决定钢球点火的初始速度。电机的***大转速为3000 0r/min。
The throwing head is driven indirectly by a variable frequency motor. After changing the frequency of the motor, the rotational speed of the throwing head can be converted to Jiangsu NSK bearing. Under the action of centripetal force, the steel ball spatter from the hole of the impeller axis to the blade, and then the blade is thrown off the solid angle with the high speed rotating blade. The speed of the impeller determines the initial speed of the ignition of the steel ball. The maximum speed of the motor is 3000 0r/min.
当江苏NSK轴承抛头旋转时,球会不时地抛出,所以投掷头的滚轴轴的流动必须用投掷头的丰富粒子提供。球阀的球团流进入铸件。江苏NSK轴承喷丸机的输出稳定、稳定。在正常运行中,钢球的流量由可调抛头的速度而改变,即,在球的稳定输出条件下,叶轮的速度是向前的,并且在该单元中抛出的球的体积很大,反之亦然。
When the Jiangsu NSK bearing throws the head to spin, the ball will be thrown from time to time, so the flow of the roller shaft of the throwing head must be supplied by the rich particles of the throwing head. The pellet flow of the ball valve enters the casting. The output of Jiangsu NSK bearing shot peening machine is stable and stable. In normal operation, the flow of the ball is changed by the speed of the adjustable throwing head, that is, under the stable output condition of the ball, the velocity of the impeller is forward, and the volume of the ball thrown out in the unit is large and vice versa.
在江苏NSK轴承抛丸机上,每个喷嘴都有一个与之相连的电流计来显示钢球的流动。当喷丸质量不符合技术要求时,应调整电机频率。调解将通过电表所示的读数来确认调解的水平。安培表的阅读类别为0~30a。
On the NSK bearing shot blasting machine in Jiangsu, each nozzle has an ammeter connected with it to show the flow of the steel ball. When the shot peening quality does not meet the technical requirements, the motor frequency should be adjusted. Mediation will confirm the level of mediation through the readings shown in the meter. The reading category of ampere table was 0 ~ 30A.
在江苏NSK轴承喷丸过程中,表面受到钢球的强烈冲击,产生变形硬化层。江苏NSK轴承将导致两种结果:亚晶粒细化的形成、位错密度的增加、晶格畸变的强化和高微残余应力的引入。此外,由于钢球表面粗糙度的增加,在切割过程中锋利的刀痕会变得更加复杂。这些变化将显著提高数据的***性和抗应力腐蚀性,从而显著提高齿轮的使用寿命。
During the shot peening process of NSK bearing in Jiangsu, the surface is strongly impacted by steel balls, resulting in deformation hardening layer. The NSK bearing of Jiangsu will lead to two results: the formation of sub grain refinement, the increase of dislocation density, the enhancement of lattice distortion and the introduction of high residual stress. In addition, as the surface roughness of the steel ball increases, the sharp knife marks will become more complicated during the cutting process. These changes will significantly improve the fatigue resistance and stress corrosion resistance of the data, thereby significantly improving the service life of gears.
江苏NSK轴承锻造中的缺陷包括外部缺陷和外部缺陷。锻件的一些缺陷会影响后续工序的加工质量,其中一些严重影响锻件的性能,降低产品的使用寿命和产品的安全性。因此,为了提高锻件的质量,防止锻造缺陷的发生,应采取技术对策,以提高整个生产过程的质量控制。
The defects of NSK bearing forging in Jiangsu include external defects and external defects. Some defects of the forgings will affect the processing quality of the subsequent process, some of which seriously affect the performance of the forgings, reduce the service life of the product and the safety of the product. Therefore, in order to improve the quality of forgings and prevent the occurrence of forging defects, technical countermeasures should be taken to improve the quality control of the whole production process.
