Why
need SMED Quick Die-Change System:
With the increasing competition in the
market, plastic products faster replacement, the coexistence of more and more
varieties, many varieties, small batch production, Francis production will
become the mainstream, especially for the automotive industry supporting
enterprises, whether it is or will be interior trim, parallel, for different
models of complete. Provide qualified products. Therefore, the time interval of
the mould replacement will become increasingly short, that is to say the mould
replacement frequency will be higher and higher, the corresponding injection
molding machine downtime will greatly increase, seriously affect the production
efficiency and machine utilization rate, the delivery period is prolonged,
large investment can not be effectively return. This situation has caused the
domestic production and use of injection molding machine manufacturers
attention, in the injection molding processing automation if not effectively
solve the problem of quick die change, other production automation degree high
is difficult to fully To improve the utilization rate of equipment, improve
production efficiency, the whole set of equipment can only be regarded as
strong, flexible response to "lame". And this problem in Western
industrialized countries has been basically solved, namely: the quick die
change system.
Developping stage:
(1)Pull type rotary machinery
This is a quick die change system early,
typical products from the Swiss company "Staubli". The characteristics
of the system are: die clamping back center, suitable for small and
medium-sized injection molding machine. The mechanical structure is more
complex, in the rear part of the mould clamping force back center. The
advantages of this system are: die around completely open, no any clamping
element for external pipe plug. The system's weakness is: die back shall be
installed with uniform clamping mechanism. The clamping force and no back
around, wear large mold deformation work, clamping parts of the component wear
serious, no clamping element state feedback signal supply system installation,
host. Maintenance is difficult, not suitable for retrofitting existing
equipment.
(2) Hydraulic press plate
This is the most widely used rapid die
change system, typically from Enerpac, US Aerostar, Pascal from Japan.
Now in Ningbo China,we R&D
ourselves,and develop our own hydraulic press plate,widely applied in injection
and stamping/punching/die casting facilities during the process of die
change/mold change.
(3) Magnetic chuck type
This is the rapid development in recent
years, American industrial developed countries is widely accepted and adopted
the quick die change system, typical products from Italy TECNOMAGNETE
(tecnomagnet) company, has more than 10 years of development of this product,
production and application experience of nearly 10000 system is applied to all
over the world, especially for the automotive industry supporting
manufacturers. In recent years, the Swiss Staubli company and Pascal company of
Japan also started from the traditional hydraulic steering system for mold
development and sales force system. The system is characterized by structure
and control is very simple, without any mechanical clamping elements and
movement in the mold plate and the suction pole on the contact surface, no
matter is the heart or peripheral, all permanent magnetic clamping, injection
molding machine is suitable for various types and specifications. The
advantages of this system are: convenient installation, hydraulic and fully
electric injection molding machine is suitable for various specifications,
clamp Force from the permanent magnetic materials, without electrical work, a
clamping state real-time signal feedback to the host, to ensure absolute safety
clamping; full contact surface due to uniform clamping force, mold in
deformation and wear a small, precision injection molding and good consistency,
prolong service life of moulds; die around without any actuator the utility,
periphery pipeline. Without mechanical movement of the system, mechanical,
electrical transient electrical, therefore in use without maintenance, life is
very long. The weaknesses of this system is: magnetic template thickness (54mm
54mm) has a certain effect on the small mould opening stroke.

The author's investigation found that the current rural agricultural equipment is still lagging behind, affecting the increase in farmers' income and income. To this end, we must use scientific development concepts to guide agricultural production, improve the level of agricultural serialization, mechanization and informatization, and increase land output rate, resource utilization rate and agricultural labor productivity. 
[China Agricultural Machinery Industry News] Agricultural mechanization technology promotion is an important part of agricultural technology promotion. Agricultural mechanization is an important symbol of advanced productivity and a carrier for the implementation of all agronomic techniques. Agricultural mechanization is an indispensable material condition for realizing agricultural industrialization, and the promotion of new agricultural machinery and new technology is an important means to promote the transformation of scientific and technological achievements into real-life productivity.
Agricultural machinery promotion work needs to be combined with the actual needs of farmers
Developing modern agriculture is inseparable from agricultural mechanization and agricultural machinery promotion
Agricultural mechanization is the modernization of agricultural production conditions and means, an important symbol of agricultural modernization, and also a representative of rural advanced productive forces. The promotion of new agricultural technologies, saving agricultural costs and increasing economic benefits are inseparable from the development of agricultural mechanization. Agricultural mechanization plays a huge role in accelerating the rural areas and building a new socialist countryside, which is fundamental, leading, carrier and guarantee. Therefore, the development process of agricultural mechanization is the development process of modern agriculture. The development of traditional agriculture to high-yield, environmentally-friendly modern agriculture must accelerate the transformation of agriculture from resource-dependent to knowledge-dependent. Modern agricultural work technology needs extensive application by farmers to be transformed into actual productivity, and the cultural level of farmers often does not reach the level of independent and accurate application of technology. Therefore, it is urgent to have a strong agricultural machinery technology training and promotion service team as a communication platform, and then improve the scientific and cultural quality of farmers' friends to meet the requirements of modern agricultural development.
Difficulties and challenges in the current agricultural machinery promotion work
The current difficulties in the promotion of agricultural machinery, first, lack of mental preparation. Ideological concepts can not adapt to the development of the situation. Some agricultural machinery extension personnel are aging knowledge, lacking the enterprising spirit of advancing with the times and the confidence and courage to meet the challenges. Second, the equipment structure is unreasonable. The varieties of agricultural machinery promoted are small, low in level and poor in performance, and cannot meet the needs of agricultural production development. Third, the technical reserves are relatively backward. At present, most of China's agricultural machinery in Daejeon operation machinery is mainly based on ploughing and harvesting machinery. There are not many kinds of machinery for aquatic products, animal husbandry, forestry and fruit, and there are not many varieties of agricultural equipment and agricultural and sideline products processing machinery. Fourth, the promotion system is not suitable. The current agricultural machinery technology promotion system still uses the operational mechanism of the planned economy period, and the administrative promotion methods of the financial allocation based solely on the plan are backward and obsolete. The outstanding performance is that the promotion personnel lack a deep understanding of the market demand, and the promotion and production are actually out of touch. At the same time, the existing agricultural machinery promotion system also has many problems in terms of institutional setup, personnel quality, working methods and operational mechanism. The work efficiency is not high, the promotion efficiency is not good, and it is not suitable for the requirements of rural management system and market economy development.
Future development of agricultural machinery promotion work
First of all, to develop advanced technology projects that are advanced and applicable, it is necessary to prioritize the promotion of technologies or machinery with less investment, quick results, and comprehensive benefits. The selection and introduction of new agricultural machinery and new tools must fully take into account their various Whether the content meets the local agricultural production needs and the overall goal of agricultural machinery development.
Second, promote the organic combination of agricultural machinery and agronomy. Agricultural machinery and agronomy have been difficult to cope with for a long time, mainly because crop varieties and farming systems are constantly changing, and agronomic requirements are also changing. It is difficult for agricultural machinery to adapt to this change. The organic combination of the two is to absorb the participation of technical personnel from various industries and departments. Second, the establishment and promotion of the agronomic system is conducive to the completion of agricultural machinery operations, and the agricultural machinery operations must meet the agronomic quality requirements. The third is the joint agricultural machinery and agronomy. Conduct comparative tests or set up demonstration sites.
After that, we will do a good job in coordinating services and promote the healthy development of the promotion work. In order to promote the healthy development of agricultural machinery technology, it is necessary to do a good job in promoting the socialization of agricultural machinery technology. First, through the leadership of the competent department of agricultural machinery, report to the local government to win the leadership's attention and support, and strive for the appropriate inclination of the relevant departments in terms of policies, funds, and materials, and provide farmers with information on technology, market and benefits through multiple channels; Various forms of training courses to help farmers learn the methods and safety, maintenance and maintenance techniques applicable to new technologies or new tools; mainly to the rural areas of townships and towns, and often go to the field to provide on-the-spot guidance to farmers. General technical issues should be technically trained to enable farmers to achieve better economic returns.
