- Q:How to solve casting defect casting?
- Different defects, different solutions, some shortcomings, the current domestic level can not be resolved
- Q:What are the factors affecting the machining process of the casting material and structure?
- As for the metallographic structure, usually the finished products after casting are treated by heat treatment. The mechanical properties of the carbon steel after heat treatment (quenching and tempering) are detected. The stainless steels are treated by heat treatment (solid solution, etc.) and the metallographic structure is analyzedThere is a lot of talk and a bit of confusionIf you have a specific brand, you can search for Baidu or buy tools
- Q:How to calculate the price of casting parts?
- Cost of raw materials + electricity (fuel) costs + workers' wages + managers' wages + transport costs + raw materials burned + accessories costs + equipment maintenance depreciation costs + management fees + tax. The most convenient, the raw material market price plus 2000 yuan, plus you want profits on the line.
- Q:Younger brother is to do casting valve, precision casting parts, the valve internal sand serious, but the appearance is very standard, this is why, for God answers, thank you!
- If is casting, internal shell mold may be not completely dry, strength is not enough, resulting in shell mold collapse into molten steel.It is also possible that the refractory is not refractory enough.
- Q:Where is the precision casting factory?
- Everywhere is. Look what you want to do
- Q:Cause of choking of casting parts
- The reason is not in the coated sand, see coating gas evolution, the best use of zircon powder coating (low gas evolution), there is a mold according to a vent needle, this depends on your way is flat or vertical pouring pouring pouring, if vertical pouring, venting pin on the die, and the big piece how could the plane, pouring water flat, a breath, a taboo ah!
- Q:What should I pay attention to when designing a casting structure?
- (2) in the prevention of metal mold casting misrun and cold partition should pay attention to the following problems: the structure of A casting thickness should be appropriate not too thin, especially when casting size when not too thin; the B should avoid a big level, because it makes the liquid metal in the casting. Rise slowly, and the air contact surface, easy oxidation, and because the metal type liquid metal heat quickly, quickly lose liquidity, easy to cause misrun and cold lap, slag and other defects; C casting shape should be streamlined to avoid sharp corners and has sharp change connection structure in order to facilitate the flow of liquid metal. 2 in the design of metal castings in a complex shape, if the production process is very difficult, should not affect the casting conditions, try to make the casting has simple shape, strong structure change, removed from metallic die for.
- 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!!
- Problem one,1, according to drawings, castings, material requirements and machine power, choose the right diameter of roughing tools, and can process this material blade type.2, according to the actual size of the casting blank, calculate the number and path of the knife, pay attention to small cutting depth, large feed, cutting width, to ensure that the tool diameter 80 - 90%, the amount of not full knife cutting, this tool and machine tool damage.Question two,If they can not change the casting blank allowance under the condition that the quantity large diameter cutter, such as milling cutter main angle 7560 degrees can give reasonable processing parameters, the same cutting depth should not be too large, because in the same machine power, tool diameter increases, cutting depth will need smaller.
- Q:What are the general technical requirements for casting parts?
- No matter what kind of material casting, there are the following major requirements:Material requirements. Mainly hardness, tensile strength, elongation, impact toughness.Two, dimensional accuracy and shape accuracy. Different castings have different requirements. Different sizes and geometric tolerances and different tolerances are adopted.Three, according to the use requirements, the casting of other defects, acceptance requirements. Such as holes, sand holes, shrinkage, slag, sand, crack.........Four. Requirements for defect repair.
- Q:There is a little trace of polishingShock polishing is even worseElectrolysis can not be uneven, there is a slight bump
- Buffing should be better, to see how your embryo, but a bit difficult
