To ensure the quality of CNC bending machine dies, first we must have a comprehensive understanding of CNC bending machine tooling quality, must from product quality conforms to the narrow concept of quality as required, extended to the quality concept of generalized, that is not only the product quality to meet the requirements, should also include CNC bending machine die itself quality, life, reliability, production cost, manufacturing cost etc.. To measure from the aspects of technology, economic point of view, the establishment of CNC bending machine tooling quality comprehensive concept. Secondly, we must improve the work quality manufacturing quality assurance of the quality assurance system, to ensure the quality of CNC bending machine tooling.

The quality of CNC bending machine tooling production work includes three aspects: design work quality, production management, customer service quality service quality; quality mainly includes two aspects: the processing quality of the parts, CNC bending machine tooling loading test quality.

The quality of 1 design work

A series of CNC bending machine tooling production: raw materials, standard parts procurement and supply, blank preparation, machining, assembling and debugging, CNC bending machine tooling quality inspection, production management and so on, are designed according to the. Design is the base of CNC bending machine die production, design quality directly determines the quality of CNC bending machine dies, you must first do a good job.

(1) the design standards of CNC bending machine dies is the basic way to ensure design quality. CNC bending machine tooling standard is the theory and practice experience of manufacturing CNC bending machine die summary. Our center has developed a number of CNC bending machine tooling standards, as long as it can seriously according to the standard design, enhance the degree of standardization of CNC bending machine die parts, extensive use of standard parts, to ensure the quality of CNC bending machine tooling to lay the foundation.

(2) according to the need, for the necessary investigations and studies, including understanding of relationships in the product parts and components, technical data of equipment and materials used in CNC bending machine tooling and situation, understand the production schedules and yield, for product design, technology and CNC bending machine tooling, operation personnel the views collected, CNC bending machine tooling design, manufacture, use relevant information and so on, it is very necessary to design a reasonable.

(3) the application of value engineering method, in order to meet the production quantity and quality of the parts, the advanced CNC bending machine tooling design, technical requirements of economic rationality, organic process combined with rice, the shortest period, the most economical cost, CNC bending machine tooling to produce customer satisfaction, make both sides can achieve the best economic benefit.

(4) audit proof work is to design a test, is to guarantee the quality of design is important one off. Not only to examine whether the design is reasonable, whether there is a technical problem, but also should pay attention to drawing is wrong, should be good correction, the error eliminating in production. In order to enhance the proofreading responsibility, such as design causes of quality problems, proofreading should bear the joint liability.

(5) continue to improve the design quality of personnel, a plan for continuing engineering education work, to understand the new trend of domestic and foreign CNC bending machine tooling technology development, master the new technology at home and abroad all kinds of CNC bending machine dies, to be applied in practice. To enrich the design experience in practice, to the deep production site, the whole process of production of CNC bending machine dies, problems resolved in a timely manner, to prepare the relevant records, change the drawings, to accumulate data:

(6) actively create conditions, application of CAD / CAF / CAM technology in the design and manufacture of CNC bending machine dies, it is guaranteed that the route one must take CNC bending machine tooling quality.

2 production management quality

This is the relationship between CNC bending machine dies quality guarantee

Pay attention to the production preparation work, according to the design requirements, to reduce the blank preparation, as soon as possible to provide CNC bending machine die standard parts, improve the CNC bending machine die standard parts of the degree of commercialization, to ensure that the CNC bending machine die quality, shorten the production series CNC bending machine tooling period to provide material guarantee.

(2) to strengthen labor management, pay attention to improve the operator's quality, often with "quality first" idea, strengthening technical training, develop training, operation contest, form a kind of consciously study technology atmosphere, to reverse the current technical level decline in the situation as soon as possible, creating a strong quality consciousness, excellent technology technician.

(3) the plan from the user needs, the work of CNC bending machine tooling production should be planned, problems to take timely measures to resolve, to CNC bending machine tooling parts completeness as the center for production scheduling work, ensure that the numerical control bending machine die manufacturing in all links are on schedule input-output.

(4) to strengthen quality management work. In order to realize the total quality management, not only to the quality management of machining, CNC bending machine tooling assembly, should also carry on the quality management of the work includes the design. Quality veto system should be implemented, the one-sided approach to change only reward and no punishment or penalty manufacturing quality problems, not to punish the quality of work. Often carry out quality activities in various forms, quality improvement, quality analysis, evaluation of quality of CNC bending machine tooling design, manufacturing award etc.. Maintain strong quality awareness, to understand CNC bending machine tooling people to manage CNC bending machine tooling quality, to quality management work of the production site, to do a good job in advance prevention, on quality management reasons caused by error, on the quality of management personnel to speak, also belong to the unqualified products, and the operator should be the unqualified products as treatment, so as to enhance the quality of management responsibility.

The 3 part machining quality

To strictly implement the disciplinary process, operating according to the technological process. To ensure the integrity of the equipment, tools, updating equipment.

To produce the qualified products to create good conditions. Attention should be paid to the quality of heat treatment, avoid due to improper heat treatment of hidden trouble. Due to the polishing quality cavity directly influence the outward appearance and quality, and polishing workload, accounting for about 1/3 to 1/4, high labor intensity, skills and strong, we must pay high attention to. Using new technology and new technology, to ensure and improve the quality of CNC bending machine tooling. To the processing quality of strict control of each procedure, ensure the unqualified products not to flow to the next step, the qualified parts create good conditions for the CNC bending machine tooling assembly.

Nonconforming parts of processors, it shall be treated according to the unqualified products, but after treatment still can use that is another matter, must not be as qualified well, otherwise it is difficult to improve the quality of.

4 CNC bending machine die assembling and testing quality

CNC bending machine tooling assembly is the key to the final decision of CNC bending machine tooling quality. In the provision of all qualified parts of the case, such as the assembly process, assembly technology properly, will also affect the CNC bending machine tooling quality, and affects the part error on CNC bending machine die will be eliminated by the assembly processing. But as more and more advanced processing equipment, to partly replace the locksmith operation, make some people mistakenly think that simple assembly, especially beginners, do not attach importance to the technology, effects of some technical operation level, can not meet the increasingly high quality requirements of CNC bending machine dies, one developed country mold qualified rate of 80%-90%, in contrast, we still have a long distance, and the machining quality, especially the great assembly quality. So be sure to improve the technical level of CNC bending machine die fitter, in order to ensure assembly quality, improve the passing rate of first tryout.
