What Are Cast Parts for Combine Harvester?

As we all know, a complete machine is composed of various parts, such as a combine harvester, which is divided into a header part, a conveying trough, a threshing part, a grain tank, a walking part, and a control part of the cab.

It is small parts one by one, and the use of castings is ubiquitous, such as guide rails, driving wheels, rollers, various shells, etc.

The Casting part is also an important harvester spare part. It is like a link, tightly spliced and connected together, Forming one part after another, and the perfect fit between parts and parts forms a complete machine. We will show detailed information about the casting parts below.

What’re The Casting materials?

In addition, the properties of castings are not only affected by the process but also affected by the metal materials used, for example, they are divided into cast iron, steel, aluminum, zinc, magnesium, copper, and cast iron. Titanium parts, etc. For each type of casting, in the harvester spare parts, we often divide it into gray iron castings, ductile iron castings, malleable iron castings, etc. Therefore, everyone must learn to distinguish the harvester’s spare parts from different materials.

Gray iron castings, ductile iron castings, malleable iron castings, from the outside, the difference between gray iron castings and ductile iron castings is not big, but from the perspective of material properties, ductile iron is more resistant and more malleable. It has a very strong tensile capacity, malleable iron castings, mechanical properties are better than gray iron castings, and wear resistance and shock absorption are stronger, so the components used in these three materials are also different.

When we choose to buy harvester spare parts, So we can Pay attention to the difference between the screening materials.

What’s the Casting production process?

In layman’s terms, casting is the liquid metal that can be smelted by smelting smelted metal materials, injected into the already prepared casting model by various pouring, injection, or other pouring methods, and then cooled, ground, or machined. An object of a certain shape, size, and properties. However, the production process of different processes is very different, the properties of the castings made are also very different, and the fields of application are also very different.

At present, there are as many as 10 kinds of casting processes developed, namely sand casting, investment casting, pressure Casting, metal mold casting, continuous casting, lost foam casting, squeeze casting, vacuum die casting, low-pressure casting, and centrifugal casting. Among them, sand casting is the most used, accounting for about 80% of all castings, followed by dying castings, which are widely used in life, such as door locks, radiators, upper and lower water pipes, door handles, iron pots, gas Stove, etc.

These are castings. In addition to being used in life, castings are also more used in machinery, especially large-scale machinery and equipment. For example, all kinds of machine tools, large machinery used in mining, heavy machinery, and so on.

In the harvester, various casting spare parts also occupy an important position, such as guide rails, driving wheels, rollers, various shells, etc. In the harvester spare parts, the commonly used processes are sand casting and pressure casting. The traditional casting process has great flexibility, wide applicability, and low cost.

On the basis of retaining the advantages of the traditional casting process, sand casting is especially advantageous in the production of materials with poor plasticity such as cast iron, such as guide rails in harvesters. In addition to these advantages, pressure casting can also be mass-produced.

While improving production efficiency, ensures that the product size remains stable and the product quality is good. Therefore, these two technologies are often used in the production of automobiles or machine parts.

For other casting processes, in machinery, especially large-scale machinery, and equipment, such as various machine tools, large-scale machinery used in mining, heavy machinery, etc., those that require higher machine precision are used more widely. Therefore, it also provides great support for the development of my country’s heavy industry.
