control the thickness of 3mm or less worn journal

Presser roller journal wear surface of the welding process


Rate of about 500mm/min. f51 regulate gas flow 15-17L/min. (61 journal surface of the water clean, oil and other impurities. 2 welding methods and materials to choose from CO gas welding method for welding journal wear surface Select O.8mm the H08Mn2Si wire as filler material, shielding gas is pure CO gas 3 times to determine the welding parameters welding process by comparing test results to determine the welding parameters as shown in Table 2. 4 welding process and operation points (1) control the thickness of 3mm or less worn journal, that the diameter of t , 63l 'production and application of hail Hui tuck Volume 37 table 2CO gas welding process parameters to reduce the 6mm should be repaired, or welding thick layer will increase the welding stress. f2) using fine wire and small heat input welding art, minimize stress and weld fusion welding ratio. (3) ensure that the level of welding torch angle of about 80 with the journal. , And to weld pool in a semi-vertical position welding down welding position,ed hardy danmark, its highest point from the journal of the horizontal distance of about 20mm, to get a good weld, shown in Figure 5. Figure 5 in advance the amount of non-Yi f4) welding the first layer of weld, the weld pressure off after a 2 / 3 before a weld to reduce the fusion ratio. f5) For the second layer of weld seam, the first layer of weld must be cooled to room temperature before welding, and after a weld in the pressure over 1 / 3 to 2 / 3 before a range of weld changes to meet the requirements of f61 solder thickness after welding by ultrasonic testing after passing the required cutting surface of the journal plus 1.5-benefit analysis using the results to the results of journal use welding 5.1 passed the test of the 23 presses roller with the result that the effective one for more than 18 months after the journal has not been found and the R-bit crack, welding of the journal over the past 3-5 months with cracks on life than to improve the 3.6-6.0 times. 5.2-benefit analysis of sucrose wide Cecil Township reputation, the country's total annual output of sugar cane sugar output more than 70% according to statistics that, Guangxi sugar industry of about 110 existing, with a different number of roller presser about 4500,tory burch uk, the annual journal only because of presses required to wear welding repair accounted for 10%. Gang this,ed hardy suomessa, the welding method of Ding Yi's successful research and application, the calculation only after the repair to improve and extend the life of the journal repair time again, the sugar industry in Guangxi will generate considerable economic benefits. 6 Conclusion (1) passed the test after welding the presses journal in the use of a relatively short time crack or fracture due to fatigue cracks and fatigue fracture caused. Causes and the journal within the welding residual stress, weld quality,franklin and marshall, load state of nature and its force and other factors. Large welding residual stress and fracture cracks is a key factor. (2) the use of CO gas welding method, a small heat input welding parameters (low 1r &, a small current, thin wire) and the correct technique, can minimize the welding presses journal welding welding stress and to ensure seam quality, and greatly extend the life of the repaired parts,ed hardy, thereby extending the time of its re-repair.

Beijing: Mechanical Industry Press,ed hardy, the process of oscillation tendency to speed up the convergence rate, but better to avoid the 99-free network is easy to fall into local minimum of defects.

(3) using this study to optimize network optimization methods and improved training Inverter welding power fuzzy neural network training algorithms,ed hardy kläder, and applied to the inverter spot welding constant current control fuzzy adaptive neural network control model sail mechanical science and technology, 2oo5 (81:902-905. The system of interference with rapid response capability,fitch abercrombie, but the threshold cited [51 from the cool. MATIAB toolbox for neural network theory and application. join the network during training to lose some small changes in Anhui fuzzy control: the glass of Science and Technology University Press, 1998 . rules, cause the system to control the relative error of average precision and no introduction of [61 Liu Jun, Liu lr, in China Yu. FNN controller parameters when compared to the revised threshold variation,franklin and marshall uk, this should note that in practical applications Methods Research Journal of Scientific Instrument, 2005 (1) :104-106.
