Although the copper castings are small in size, in the mechanical industry, the performance, functions and so on can not be achieved by many accessories, and the specific use is not only related to its parameters, but before the castings are produced. Have to go through, design principles:
1, free to shrink.
2. The thickness of the copper casting wall is thinner, ensuring good mobility and preventing large shrinkage.
3. Use a large plane to tilt. Use filling and exhaust troubleshooting.
4. The copper casting has a uniform wall thickness, which can reduce the generation of stress and prevent deformation and cracking.
5, the use of rounded corners, and the use of rounded corners, cones, slopes gradually transition.
Designing copper castings must be considered from the perspective of the casting itself. In addition, unnecessary defects should be avoided during the design process.
When selecting a copper casting, the user often refers to various factors and whether its parameters are suitable for the current machine. At the same time, it is necessary to pay attention to the accuracy. As we all know, the higher the precision of the casting, the higher the quality and the wider the applicable range. Since accuracy is so important, how do you improve the accuracy of your castings? The manufacturer reminds you to do this:
1, reduce the original error
We usually use machine tools to machine cast copper parts. In order to reduce the impact of machine tools on the machining accuracy of machine parts, we need to improve the geometric accuracy of the machine tool, as well as the accuracy of other workpieces, and reduce the additional force impact of the machining process. Control the thermal deformation of mechanical parts during machining. Reduce casting machining errors.
2. Error compensation and transfer
Compensate or transfer the errors generated during the manufacturing process of the cast copper parts. By offsetting each other, the machining error is reduced and the machining accuracy is improved.
Although the error is inevitable, if there is a slight error, there is a slight error, the accuracy of the copper casting will certainly not increase, but the other machines will also be affected because of the decrease in precision. Therefore, we must always pay attention to the error of castings.
