Half-clamp for large pieces of gear wheels Shao} j * chasing the success of split bamboo and other bamboo walls and become real rejection of the Yan Meng chase show.

Copper is a large and complex pieces. According to the characteristics and the former producing similar pieces of casting experience. Development of appropriate casting process to produce the 10 casting, the indicators have to meet the design requirements. First,uggs ireland, the casting of the structural characteristics of the technical requirements bearing in mind that half of gear gross weight 5950kg, requires no casting shrinkage, reduced press. Pores, trachoma. Cracks, deformation and other casting defects, non-working side of the surface quality is better. In addition,ugg boots sale, the outline size of ~ 4460x464mm. Sash and the inner edge of outer wall thickness difference and the height difference between the larger, respectively, 11Omm with 142mm, 464mm and 135 ~ 105ram. Reduce the convergence board has holes, it is T-shaped and oblique pull Wei's wall thickness 50ram. And the casting is a semi gear ring, prone to cracking and deformation. =, Process analysis 1. Modeling method of choice for large differences in wall thickness of casting. Prone to cracking and deformation of the take out 3 Pei Ying bearing in mind that the performance ratio of powder coating T_h. ropertylndin2redntofzlreoncoati material expansion of zircon powder Wei soil l J l dextrin rosin potassium l I re-training the proportion of water I!:::: 111:. !: 111:!! Bus!: Two for the dry soil core temperature of 150 ~ 180 ℃, holding time is 2 to 3 hours. Fifth, the remaining scale parameters 1, 0.8% 2. Allowance, the top 20. Bottom 14. The remaining 12.3. Pouring temperature 1350 ± 10 ℃. 4. 1.5 hours after pouring waving fastening bolts hit me for 96 hours. 30 features, extensive use of limestone and silicate sand I'm the hot sand is good compromise. Beneficial in reducing stress cracks. As a large casting size, production characteristics of small quantities. Therefore, the core group of sand pit shape. 2. The choice of sub-surface level we have chosen type. The casting process diagram of Figure 1.3 determine the process parameters within a large round of castings solidification shrinkage out different, we determine the diameter of incorporation rate of 1.8%. Diameter shrinkage rate of 15%, 2% in the height direction. Core negative for the 1 ~ 1.5mi11.4. Riser system according to the design of gating system stable, dispersed, decompression, buffering, and the principle of solidification,GHD glätteisen günstig, designed for multi-channel gate, bottom water injection method coupled riser. Sprue, runner and the runner 4o respectively 80,40 and in the shape of the runner refractory pre-Pina. The runner is divided into seven, EF straight: I: F: I: F = 1:1.75:】. 75. Set in the center near the straight gate, the gate is located in the core # 1. VI Conclusion I plant in the depression year of the two successful water body, special pieces of visual quality,ugg boots ireland, child any size, processing conditions have received good results. Summary of the process, the main features as follows: ① Fortunately, the special structure of the body}. Taken back to the gate and the bottom riser overflow. Practice shows. Gating system in the leaf size, the larger scope of change, and not lead to produce short roads, water lying within the system structure and the introduction of the location of the gate right or not. More sensitive to the casting quality. @ Assembly mold towels, clear the casting base, to take a mud core coordinate system orientation. Improve the accuracy of the casting geometry, making a successful machining crossed, avoids the large cast in the size of this loss is the phenomenon of care. References Linbo: \No6.
