The Kong Shuang cone roller in the bearing ring way quenching inductor design improvements

The Kong Shuang cone roller in the bearing ring way 2019 - quenching inductor design is improved 09 - 08 Cao Qing xie wen ( Hubei liberal arts college institute of technology; Shiyan day shu induction equipment co. , LTD. ) 1. Technical background is the original technical proposal in reference Shen Weiyi waiting 'truck wheel hub bearing outer ring induction quenching are, on the basis of increased part discussed and analyzed. The original sensor structure is shown in figure 1, quenching sample piece as shown in figure 2. Figure 1 original sensor solutions figure 2 original sample processing piece of photo 2. The technological process, 1) Complete the upper cone quenching. （ 2) The second clamping, complete underside quenching ( For the spray cone on quenching area are protection) 。 The original plan process parameters as shown in table 1. 3. The original plan pros and cons advantages: (1) sensor made simpler. (2) the process adjusting difficulty smaller. Disadvantages: (1) parts requires two clamping. (2) need two sets of tooling. (3) parts need to flip 180 & deg; And automation equipment mechanical action implementation is difficult. (4) the second cone quenching tempering on quenching area for the first time, for the first time the water spray quenching area are protected, change point increase. 4. Sensors and processing method for these sensors can improve the shortcomings, so up and down heating at the same time in the design of new type fan sensors ( See figure 3) , a clamping parts, complete cone up and down heating quenching at the same time. Figure 3 new fan a heating double cone sensors ( 1) Implement specific steps: first step, the material level ( A clamping workpiece, as shown in figure 4 a) ； The second step, probe into the workpiece lumen ( As shown in figure 4 b) ； The third step, sensors to heating, the workpiece rotation, heating ( As shown in figure 4 c) ； The fourth step, after heating, sensors to spray quenching ( As shown in figure 4 d) ； Fifth, sensors from the blanking parts lumen to ( As shown in figure 4 e) 。 Figure 4 new sensor processing steps ( 2) Improvement plan process parameters are shown in table 2. （ 3) Quenching sample testing results of the new scheme as shown in figure 5, test results as shown in table 3. Figure 5 new quenching sample block 5. Conclusion clamping scheme need a second to complete the whole parts quenching, a new scheme the clamping only once to complete parts quenching, improve the production efficiency, increase the production capacity of enterprise, a clamping simplifies the mechanical loading process, sufficient technology reserve for mass production.
