Manufacturing process challenges of special-shaped locks
I. Introduction
Special-shaped lock is a kind of lock product with nonstandard shape or special structural design, which has a wide application prospect in various high-end application fields, such as aerospace, precision machinery, automotive electronics and other fields. However, due to its unique structural characteristics and strict functional requirements, it faces many insurmountable technical problems in the production process.
Second, material selection and processing difficulty
1. Material characteristics: In order to meet the performance requirements in different use environments, special-shaped locks are often made of high-strength alloy steel, titanium alloy and other materials. These metal materials have high hardness and good toughness, but they also bring great difficulties to subsequent cutting.
2. Special shape: In order to realize the anti-theft function, the lock body is usually designed into a complex and changeable curved surface or hole form, which increases the uncertain factors in the molding process of mechanical parts.
Third, the problem of precision control
For any kind of industrial products, "size is life", especially for those parts that need a high degree of precision to work normally. Therefore, how to ensure that each component can be assembled accurately has become the key point of the whole project. Specific performance in the following aspects:
1. Micro-gap treatment: Because the internal structure is very compact, even micron-level deviation will affect the overall operation stability;
2. Surface roughness requirements: it is difficult for traditional tools to achieve enough smoothness, and the risk of deformation may increase if they are over-polished;
3. Difference of thermal expansion coefficient: When the temperature changes, the phenomenon of thermal expansion and cold contraction between different materials will lead to the expansion of the original gap and even cracks.
Fourth, the bottleneck of improving automation
With the development of science and technology, more and more enterprises begin to try to introduce intelligent production lines to improve efficiency and reduce costs, and monitor product quality online by integrating sensors and visual inspection systems to reduce the probability of human error. However, in the face of some specific tasks (such as texture recognition of special-shaped surfaces), it still seems inadequate. The main reasons are as follows:
1. Insufficient data collection: lack of effective means to obtain comprehensive and accurate data information as a resource library for training basic models;
2. The generalization ability of the model is weak: at present, most commercial software frameworks on the market are only suitable for learning algorithm modeling tasks in standardized scenarios, and it is difficult to directly migrate and apply them to the detection of new special-shaped lock products;
3. Poor equipment compatibility: The existing production equipment can not well support the switching operation process of samples with various specifications, resulting in long debugging period and high failure rate.
V. Conclusion
To sum up, it can be seen that although some progress has been made in the current technical level, there are still many problems to be solved waiting for us to explore and conquer. Only by constantly innovating in science and technology and optimizing and improving with the characteristics of practical application scenarios can we finally achieve the real goal of manufacturing special-shaped locks with high efficiency, low cost and high quality.
