Bronze Bushing Characteristics and Processing Attention Problems
Bronze bushing, also known as straight sets, straight copper sets, straight bushings,
bushings, etc, often made of materials include: brass, tin bronze, lead bronze, aluminum bronze,
phosphor bronze. Bronze bushing is a mechanical equipment in a component, mainly used in mining
machinery and equipment in the application process, copper liner is an indispensable parts, copper
liner used. The main materials are brass, bronze, aluminum bronze, phosphor bronze, lead bronze,
made by sand casting and centrifugal casting process, copper bush and other copper products have
their own characteristics.
1. Wear-resistance. Copper liner wear resistance is better, different materials have
different characteristics of the bushing, centrifugal casting out of the copper liner inside the
organization is relatively tight, there will be no loose and stomatal trachoma and other
phenomena, centrifugal casting out,the copper bushing hardness is relatively high and durable.
2.Corrosive. This is another feature of copper bushing, corrosion performance is relatively
good, mainly used in the atmosphere and fresh water, in the use of copper bushing in the process,
generally not prone to bite the situation. Corrosion is mainly reflected in a number of chemical
elements, such as: dilute sulfuric acid, hydrochloric acid and fatty acids, etc, so that the
corrosion resistance of copper bushing is very good, it will not produce the main situation or
because of their own characteristics, even if there is no lubrication. The case of the case can
still be normal work.
3.Compressive capacity. Copper bushing has good compressive capacity, especially the surface
pressure is large, can withstand the bearing side pressure, in the case of high load pressure,
copper bushing can still operate.
These are some of the main features of the bronze bushings, and that is his casting
performance and cutting performance will be good, so the bronze liner is a mining machinery and
equipment in an indispensable parts.
Bronze bushing processing shoud pay attention to the problems:
1.In the sintering of the bushings, the process must be carefully handled, such as the box
required to put the core is correct, so that the casting out of the product due to this reason
can not be processed by size.
2.In the processing before the first to clean up the castings, and then on the train, first
corrected, and then processed to the semi-finished product when the car, cooling, because the
copper has a shrinkage, in order to be accurate to the workpiece at room temperature when re-car
3.After the finished product, especially the straight set can not be placed should be placed
vertically to prevent deformation.
4.Packaging, to keep the amount, to avoid in the transport process by accidental collision
