What are the design principles and testing methods for the processing of non-standard parts?
Processing of Irregular Parts What are the design principles and testing methods for irregular part processing?
Design Principles of Irregular Part Processing:
1. Irregular part processing must meet product use and technical performance, and be easy to assemble and maintain.
2. Irregular part processing should help improve the utilization rate of metal materials, reduce the variety and specifications of materials, and reduce material consumption as much as possible. Where possible, low-cost materials should be used, and part blanking should be as waste-free and low-waste as possible.
3. Irregular part processing should have a simple shape and reasonable structure, which is conducive to simplifying the mold structure and the number of processes, that is, using few and simple stamping processes to process the entire part, reducing other methods, which is conducive to stamping operations and facilitates the organization of mechanized and automated production, thereby improving labor productivity.
4. Under the condition that the designed stamping parts can be used normally, the dimensional accuracy grade and surface roughness grade requirements should be as low as possible, which is conducive to product interchangeability, reduces defects, and ensures stable product quality.
5. Irregular part processing should make the best use of existing equipment, process equipment, and processes, and extend the service life of stamping dies.
Testing Methods for Irregular Part Processing:
A Rockwell hardness tester is used to test the hardness of irregularly processed parts. It can be used to test small stamping parts with complex shapes. If the plane is too small, it cannot be tested with a common desktop Rockwell hardness tester.
Irregular part processing includes blanking, bending, stretching, forming, CNC machining, and finishing. Irregular parts are mainly made of hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel plates, alloy steel plates, spring steel plates, galvanized plates, tin-plated plates, stainless steel plates, copper and copper alloy plates, aluminum and aluminum alloy plates, etc.
The PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. Irregular part processing is a common part in metal processing and mechanical manufacturing. Irregular part processing is a processing method that separates metal strips or shapes them with molds. Its application range is very wide.
The main purpose of hardness testing for irregularly processed parts is to determine whether the annealing degree of purchased metal plates is suitable for subsequent processing of stamping parts. Different types of stamping parts require different hardness grades of plates. Aluminum alloy plates used for irregular part processing can be tested with a Vickers hardness tester. When the material thickness is greater than 13 mm, a Brinell hardness tester can be used instead. Pure aluminum plates or low-hardness aluminum alloy plates should use a Brinell hardness tester.
I believe that through the above introduction, everyone has a better understanding of the design principles and testing methods of irregular part processing. If you want to learn more about this aspect, you can contact us. We can introduce it to you from different aspects to give you a more detailed understanding.
