First, the arrangement of the fine parts processing should be based on the construction of the parts and the blank condition, as well as the requirements of the positioning and clamping, the emphasis is on the rigidity of the workpiece is not destroyed.
1. The processing of the previous process can not affect the positioning and clamping of the next process, and the intermediate cross-section has a general fine part processing process.
2. First stop the inner cavity cavity adding process, then stop the shape processing process.
3. It is better to stop the process with the same positioning, clamping method or the same tool to reduce the number of repeated positioning, the number of tool changes and the number of moving platens. Shenzhen machining
4. In the multiple processes that are stopped in the same device, the process of destroying the rigidity of the workpiece should be arranged first.
Second, the tool concentration sorting method: It is to divide the process according to the tool used, and use the same tool to machine all the parts on the part that can be completed. Use the second knife and the third handle to complete other parts that they can complete. This can reduce the number of tool changes, tighten the dead time, and reduce the unnecessary positioning error.
Third, the processing part of the order method:
Regarding the parts with a lot of processing contents, the processing part may be partially red, such as an inner shape, a shape, a curved surface or a plane, according to its structural characteristics. Ordinary machining plane, positioning surface, post-processing hole; first processing simple geometric shape, then processing complex geometric shape; first processing lower precision parts, and processing higher precision parts.
Fastener companies not only produce fixed fastener products, but also provide processing and fastening services for users; technology and process level are important, but more important is management level, because every link of production is possible profit. In this aspect of management, we are much behind the foreign companies. There are only equipment and processes, no high-quality talents, no management guarantees, and it is impossible to supply large quantities of fasteners.
Third, fastener enterprises should pay attention to the training of technical personnel
In recent years, China's machinery, power, vehicles and other industries have developed rapidly, driving the expansion of the fastener industry's production capacity, but also brought opportunities for the development of the fastener industry. A few days ago, the problem of nearly 20,000 fastener business owners was that they could not recruit skilled workers, and experienced high-quality technicians were even more difficult.
Nowadays, there is a shortage of fasteners. Many companies are not idle because they have no orders or equipment, but no high-quality production personnel and management personnel. Talents are all trained in practice, and no ready-made people will be waiting for the company to dig. High-quality workers are one of the driving forces for a healthy, stable and sustainable development of the industry. In the past 10 years, with the rise of China's status as a major power in the world's manufacturing center, the annual output value of the fastener manufacturing industry has reached 60 billion yuan. Technological progress has promoted the development of the industry, and the development of the industry has driven technological progress. During the 13th Five-Year Plan period, The annual growth rate of China's fastener industry is expected to be no less than 10%. Compared with the manufacturing countries such as the United States and Japan, there is still a big gap in China's fastener industry. American enterprises are characterized by large-scale, automated, and digital production. The numerical control technology, network technology, and digital control technology are mature. From design to production, the degree of informatization of production management is very high. The specific performance is as follows: First, the automated production is safer and more reliable, and it is convenient for the maintenance of the entire bolt and nut production line; second, the safety awareness is high, and the safety grating is installed on the press; Third, the application of the management information system improves the management level of the company. And production efficiency, enterprises have their own management information system, raw materials suppliers supply materials with barcodes; Fourth, although the scale of enterprises is relatively large, but the product line is not much, the production volume of products is large.
Fourth, the development of fastener enterprises
A fastener manufacturer only produces several products, but it can do fine and fine, and form a monopoly on product supply. As long as these products are available, any user manufacturer will be supplied by the company. Therefore, some people say that the American model is the direction of our enterprise development; and Taiwanese enterprises are the benchmark for our company's current learning.
