Stamping mould processing industry development trend

Stamping mould processing industry development trend

Although ChinaStamping dieIndustry in the past more than ten years made remarkable development, but many aspects compared with industrialized countries there is still a large gap.Precision processing equipment in the mold processing equipment, for example, the proportion of is low;CAD/CAE/CAM technology penetration rate is not high;Many advanced mold technology is not widely used, and so on, led to quite a number of large, sophisticated, complex and long life of mould rely on imports.

In recent years, many mould companies increased the investment for technological progress, technological progress as the important driving force of the development of the enterprise.Some domestic has popularized the two-dimensional CAD mould enterprises, and gradually started to use UG, Pro/Engineer, i-deas, Euclid as-is international common software, such as individual manufacturer also has introduced the Moldflow, C - Flow, DYNAFORM, Optris and MAGMASOFT CAE software, and successfully applied in stamping die design.

Mould should be in order to adapt to the development of processing technology of mould products "short delivery time", "high precision", "good quality", "low price" service.Achieve this that are in urgent need of development of the following items:

(1) high speed milling

Abroad in recent years the development of high speed milling, greatly improves the machining efficiency, and can obtain high surface finish.In addition, it can also be high hardness processing module, also has the advantages of low temperature rise, small thermal deformation.The development of high speed milling machining technology, cavity mould manufacturing in automotive, home appliance industry has injected new vitality.It has to more agile, intelligent, integrated direction.

(2) die scanning and digital system

Scanning system provides high speed scanner and mould from model or physical scanning to work out the desired model for various functions, die in developing greatly shorten the manufacturing cycle.Some fast scanning system, can be quickly installed on the existing CNC milling machine and machining center, fast data acquisition, automatic generation of different numerical control system of processing procedures, the CAD data of different format, used for mould manufacturing "reverse engineering".Die scanning system has been in automobile, motorcycle, household appliances industry successful application, believe that during the "tenth five-year plan will play a more important role.

(3) the mold polishing will be automatic and intelligent

Mould surface quality of the service life of the mold, the appearance quality of the parts, etc all have great influence, the automation and intelligence of the lapping and polishing method to replace the existing manual operation, in order to improve the quality of the mold surface is an important development trend.

(4) mold the development of the automatic processing system

This is the goal of long-term development in our country.Mould automatic processing system should be more reasonable combination machine tools;With the accompanying positioning fixture or positioning plate;A complete machine, cutting tool CNC library;A complete CNC flexible synchronous system;Quality monitoring and control system.

(5) edm milling

Edm milling technology, also known as electric spark into machining technology, this is an alternative to traditional with formed electrode processing cavity of new technology, it is a high speed rotating simple tubular electrodes for 3 d or 2 d contour machining (like numerical control milling), so no longer need to make complex shape electrode, it's clearly a significant development in the field of electric spark forming processing.Abroad have been using the technology of machine tool in mold processing applications.This technology is expected to develop.

(6) the comprehensive promotion of CAD/CAM/CAE technology

Mould CAD/CAM/CAE technology is the development direction of mold design and manufacturing.With the progress and development and popularity of the computer software of CAD/CAM/CAE technology conditions has been basically mature, the enterprise will increase the CAD/CAM technology training and technical services;To further expand the application of CAE technology.The development of computer and Internet are making CAD/CAM/CAE technology cross-regional, across the enterprise, across institutes in the whole industry to promote, realize a new integration technology resources, virtual manufacturing is possible.

(7) improve the standardization of the die

Mould standardization degree is increasing in our country, estimated that at present our country mold standard parts using coverage has reached 30%.In the developed countries generally about 80%.

(8) the high quality materials and advanced surface treatment technology

Selects the high quality steel and application of the corresponding surface treatment technology to improve the service life of mould is very necessary.Mould heat treatment and surface treatment can give full play to the key link in the process of die steel material performance.The development direction of the mold heat treatment is to use the vacuum heat treatment.Mold surface treatment in addition to improve the development process should be advanced vapor deposition (TiN and TiC, etc.), plasma spraying technology, etc.

Dalian stamping dieThe application of advanced manufacturing technology has changed the traditional molding technology mould quality depends on the human factors, is not easy to control the situation, make the mould quality depends on the physical and chemical factors, the overall level of easy to control, mould reappearance ability.
