- Q:How to cast iron and wrought iron collocation
- 2, listen: Pig beating sound boring, wrought iron beating sound loud.
- Q:The difference between sheet metal and casting parts
- Commonly used in machine tools casting material is gray cast iron, casting bearing alloys can also be.
- Q:Shandong foundry, casting small pieces of precision casting
- Dongying Huayang precision casting factory, the smallest to do 2G pieces.
- Q:How much is the casting allowance in the design of the casting machine and the drawing?
- Casting parts do not need to provide drawings of casting blank, the casting factory according to your drawings in the required surface will be sufficient allowance, and the rest of the size according to the mechanical design manual and the casting manual can be found. The general foundry casting technology division will mark put shrinkage and the allowance of the map in your chart (usually with the red pen) for the production of wood or other material wood workers die drawings.
- Q:What should I pay attention to when designing a casting structure?
- The basic structure of unit 3 in the design of metal casting casting and its parameters are 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 casting casting; (2) the inner wall of the internal ribs and the thickness of a should be connected the outer wall thickness of 0.6 to 0.7, or as the inner wall (rib) cold slowly, cracks in the wall at the junction in the casting shrinkage; (3) to prevent generating white grey cast iron, in addition to taking measures in the process, must make the wall thickness is not too thin (some information that cast fillet at the corner of the wall thickness of 15mm or more, with metal casting casting must be in the corner, for Aluminum Alloy, metal casting magnesium alloy castings shall not be less than 3 ~ 4m; (4) because of the metal type and the core that, for To facilitate the extraction of castings and casting out type, slope casting should be suitably large than sand casting metal casting, the general should be 30% ~ 50%, it should be pointed out that in addition to the height of the slope of casting size and alloy type, wall, is also related to the casting surface position, where the cooling and contraction of the metal type the surface of casting surface can be designed from the tendency of small inclination, while casting shrinkage tend to be pressed on the surface of metal casting type should be given greater inclination.
- Q:Casting parts in rocker arm drilling, reaming, roughness, block.
- Radial drilling machine can achieve boring, reaming function, but as much as you want, according to your requirements and material to determine!
- Q:We are small castings, the need for surface treatment of shot blasting machine, about how much?
- according to the comprehensive consideration of factors such as yield, size of workpiece commonly used on the market the crawler shot blasting machine has Q324, Q326, Q328, Q3210, and each time the amount of their treatment were 125KG, 200KG, 400KG, 600KG, the specific use of what types also need to be determined according to the actual situation
- Q:The casting sand is going on
- 2, causes(1) sand mold (core) strength is not high, when the box a little reason will fall off.(2) the strength of sand mould (core) is not high, it can not stand the erosion of molten steel.(3) box sand mould (core) crush.(4) high strength under high temperature, warpage, deformation and protuberance into the cast steel under the action of high temperature molten steel.(5) the floating sand in the air hole of the sand mold falls, especially when the floating sand falls in the casting, and the floating sand on the surface of the sand mold is easy to fall through the air vent.(6) when the box is closed, the surface of the mold cavity and the surface of the sand core are not cleaned, and the sand (core) surface has floating sand and so on.
- Q:What are the causes of pitting on the surface of a precision casting?
- The quality of the shell surface is out of order. Or shot blasting out of question.
- Q:Explain the heat treatment effect of casting parts, forging parts and welding parts
- The three methods of metal processing have one thing in common. They are hot working, which are different in temperature and range of processing. Ductile cast iron is widely used because of its brittleness and poor impact. Heat treatment of cast iron usually adopts the annealing process, reduce the casting effect: 1 because of the internal stress caused by the thermal expansion and contraction, reduce the deformation after machining, decrease surface hardness, improve machining conditions;
