Multiple site punching device is used in the production of automobile metal accessory
Technical field
The invention belongs to auto parts machinery production technical field, and in particular to automobile metal accessory production is filled with multiple site punching
Put.
Background technology
Realize the transformation made the country prosperous from automobile making big country to automobile, it is necessary to based on powerful parts industry.Reform
Since opening, China's parts industry is fast-developing, and enterprise independent innovation consciousness gradually strengthens, industry independent research and development capacity
Step up.But all in all, China's parts industry lacks core technology production because of capability of independent innovation wretched insufficiency
Product, numerous medium and small sized Auto Fittings Enterprises do not obtain radical change in the homogeneity competition situation of industry low side for many years, or even this
Situation is from domestic development to foreign countries.
During " 12 ", the fast-developing many internal and external factors of support China auto Parts Industry are just occurring deep
Change, China's auto Parts Industry is faced with domestic automobile industrial restructuring, international trade general layout and occurs the new shape of profound change
Gesture.The problem of China auto Parts Industry capability of independent innovation is weak has been increasingly becoming industry in itself and whole automobile industry
The 'bottleneck' restrictions of development.Accelerate to improve parts industry Construction of Independent Innovation Ability, be to promote auto Parts Industry knot
Structure optimization and upgrading in the urgent need to being to strengthen China auto Parts Industry core competitive, build the key of automobile power
Place.
As China enters the ranks of automobile superpower, automobile consumption product gradually come into the life of people, car ownership by
It is cumulative plus, motor vehicle liquidation amount is also risen year by year, and substantial amounts of harmful substance is contained during motor vehicle liquidation, if without disassembling processing
Understand and environmental and human health impacts are brought with great harm, abandoned car is disassembled available a part of old part process after recovery and made again
Use value can be realized again by making, and create economic benefit.Development auto parts and components remanufacturing industry is gradually valued by people,
The development of auto parts and components remanufacturing industry all has to society, economy, the healthy living of people and automobile industry structural adjustment
Significance.
Auto parts and components remanufacturing industry is the circulation warp of a kind of " resource-product-waste product-remanufactures product "
Ji pattern, is the most economical reparation means of junked-auto, realizes economic benefit, social benefit, employment benefit and ecological benefits
Unification.The developed countries such as the U.S. have established perfect auto parts and components and have remanufactured development service system, including waste and old part
Recovery system, Reverse Logistics System etc., in terms of the development model and development countermeasure for Chinese automobile spare parts remanufacture
Research also lacks the complete theoretical system of system.
With the fast development of Chinese society economy and science and technology, spare part mould process technology also increasingly technicalization, elder generation
Evolve, people are more likely to multi-functional, performance and concentrate and carry easily demand direction.Thus the body development of parts becomes
Gesture is less and less, increasingly precise treatment and integrated, i.e., it is towards thin, small, light, while requiring that high-precision direction is developed.
Sheet Metal Forming Technology saves material and the energy due to having for being processed than tradition machinery, and efficiency high will to operator's technology
Ask not high and can be made by various mould applications and be machined be unable to reach product, thus its purposes is more and more wider
It is general, therefore there is many to be produced by stamping technology in auto parts machinery.The accessory of some in production process is exclusive due to realize
Function, it is therefore complex-shaped, it is impossible to which that punch forming successively, this proposes higher requirement to pressing equipment.Therefore, invention vapour
Multiple site punching device is used in the production of car metal fittings, goes solution drawbacks described above necessary.
