Non Standard Tailor-Made Copper Bushing Reliable Thin-Walled Bronze Bushing

Product description

Copper sleeve is also known as copper bearing. It is a kind of component used in sliding rotating machinery to reduce friction drive thrust and play a role of supporting and fixing. The copper sleeve needs to be lubricated with oil. The copper sleeve is also made of various copper alloys to lubricate the mechanical parts.

Copper sleeves, also called copper shaft sleeves, are divided into a variety of types, including machine copper rollers, copper bearings, and so on. Used for various light industry, large and heavy machinery, it is an important component of machinery. The product has the traditional tin bronze bearing function, using electrolytic copper as the raw material and a variety of trace metal elements, sintered at high temperature, and processed by air pressure centrifugal casting. High hardness, excellent abrasion resistance, not easy to cause seizure, good casting performance and cutting performance, good corrosion resistance in the atmosphere and fresh water. In the absence of lubricants and water-based lubricants, good sliding and self-lubricating properties, easy cutting, poor casting properties, and good corrosion resistance to dilute sulfuric acid.

Production and processing

As we all know, copper sleeve has high hardness and good wear resistance, which is not easy to produce the phenomenon of seizing, and it also has good casting performance and machinability. It has very strong corrosion resistance. So it is also very careful in the process of manufacturing, so what should we pay attention to in the process of manufacturing?

The first point: when casting the copper sleeve, each process must be carefully handled. For example, the core must be placed in the right position when the box is closed, so as to avoid that the cast product cannot be processed according to the size due to this reason. The second point: before processing, first clean the casting, then get on the car, first correct it, then get off the car when processing to the semi-finished product, and cool it. Because copper has shrinkage, in order to process accurately, get on the car again when the workpiece is placed at room temperature for processing.

The following is the production process of our large copper sleeve.

1. Mix proportion according to the material required by the customer and send it to the medium frequency furnace for smelting;

2. Before pouring, the spectral analysis was carried out;

3. According to the results of spectral analysis, different metal elements are added properly to meet the material requirements of customers;

4. Centrifugal casting copper sleeve;

5. Machining;

6. Mechanical property test (tensile test, hardness test);

7. NDT to ensure no casting defects

8. Package and deliver the goods after passing the inspection
