- Q: Casting blank in the cooling process to release a large amount of heat energy, what can be recycled?
- Casting, do not need to provide a rough casting foundry drawings, according to your chart will put foot margin in the processing needs of the surface, the rest of the size can be found according to the mechanical design manual and manual casting. General Casting Factory Casting Division will be in your chart marked on shrinkage and processing margin figure (usually with red and green pen) to the patternmaker production of wood or other material mould diagram.
- Q: How to improve the surface roughness of casting parts?
- First, the accuracy of the model should be improved; two is to change the molding technique; the three is the coating; and the worker's technical level.
- Q: How do casting parts remove stress?
- Annealing treatment, according to different casting annealing treatment, eliminate thermal stress, if need to restore hardness or increase hardness, and then quenching treatment
- Q: In theory, which is more expensive, forging parts or casting parts?
- It depends on the structure. In theory, the shape of the forging is relatively simple, but the requirement of internal structure is relatively high
- Q: Casting parts have poor surface finish. What sand is used to make them?
- V casting, EPC, precision casting of the surface is good.
- Q: The difference between cement sand castings, resin sand castings and vacuum casting parts
- Our country or international, in all casting production in 60 ~ 70% by sand casting is produced, of which about 70% is used in the production of clay sand. The main reason is that the cost of sand casting is low compared with other casting method, simple production process and short production cycle. So as the car engine cylinder body the cylinder head, crankshaft castings are produced using clay wet sand molding process. When the wet type can not meet the requirement to consider the use of clay sand table dry sand, dry sand mold or other sand.
- Q: The cause of fracture and why there is no toughness
- This question is too broad, see what the casting casting Oh in order to reduce the wayward cast steel, ductile iron, gray iron and white iron, you can choose the material according to their own requirements.
- Q: Would you please tell me how to use casting parts for a year?The cast of an aircraft wing needs to be put aside for a year before it breaks;Does anyone know why?
- 3, the resonance method is cast on its resonant frequency vibration 1060ndn, to eliminate the residual stress in casting.
- Q: When the blank is a casting, the margin is evenly distributed, how should rough machining?Please help friends from mechanical classes.There is another problem: in the NC milling plane contour machining, when the rough margin is large, how to deal with.Who can help in time, add 20 reward. Urgently!!
- Personal advice:Because of the large margin, your outline is easy to guarantee;So the key is to consider the assembly and aesthetics of the casting. You have to find the machining criteria;Rough the datum so that it can be machined;After the outline, turn back to the finishing line.If the casting requirement is not high, the benchmark can be directly processed; (not recommended)Over
- Q: In the design of casting steps and precautions, for casting design, we have what experience?.
- Two: the basic structure unit in the design of metal casting type and the parameters selected, usually should also pay attention to: (1) because of the metal type heat quickly, so the metal type casting minimum wall thickness should be bigger than the sand casting, metal type casting alloy minimum wall, different size of castings see table 1.1-31 thick can be selected; (2) the inner wall of the casting internal ribs and the thickness of wall thickness should be 0.6-0.7 connected, or as the inner wall (rib) cold slowly, cracks in the wall at the junction in the casting shrinkage;
