Analysis design of process parameters of tee pipe nodular casting factory

2019-11-21 12:17:59

Casting technology is the main basis for mechanical casting manufacturers to determine casting design, production preparation, molding technology casting inspection. These process data are obtained by the mechanical casting manufacturer through the comprehensive analysis of two-piece structure, meeting the production technical requirements, ensuring the quality application conditions, improving efficiency reducing costs. These process data mainly refer to machining allowance, lift angle, casting shrinkage, minimum casting hole, core size, casting fillet, etc. Only when the process parameters are selected accurately properly can the casting size be ensured, the design is more successful the production is more efficient.

The minimum wall thickness the diameter of the castable hole of the mechanical casting manufacturer

Whether the holes, grooves, steps, etc. on the parts are cast machined should be considered the quality economic aspects. Generally speaking, large holes, grooves, etc. should be cast out to save metal processing time, at the same time, the hot spot caused by local over thickness of castings can be avoided to improve the quality of castings.

Smaller holes, grooves thick casting walls are easy to cast holes, but it is convenient to directly rely on processing.

Because of the characteristics of EPC process, the possibility of casting the smallest wall thickness hole diameter, boss, pit other small parts is greatly increased, so most of the holes of EPC process castings can be cast, the minimum wall thickness is mainly limited by EPS pattern, as long as the pattern can be made, the castings can be cast. Different casting alloys are used in production. There is a suitable limit of minimum wall thickness minimum hole diameter that can be cast.

The material of tee pipe parts is gray cast iron, so the minimum wall thickness can be cast is 4mm, the minimum hole diameter can be cast is 8mm. According to the analysis of the size requirements of casting parts, the minimum wall thickness of the casting is 5mm, which meets the requirements of the EPC process. Meanwhile, the inner diameter of the pipe meets the requirements of the minimum hole diameter, so it can be cast directly. However, for the diameter of the joint on the flange is medium 7, the hole diameter is small, It can't be cast directly, so it can be machined, which is more economical convenient.
