Description

Automobile metal accessory production multiple site punching device

Technical field

The invention belongs to auto parts machinery production technical fields, and in particular to automobile metal accessory production is filled with multiple site punching It sets.

Background technique

It realizes the transformation made the country prosperous from automobile manufacture big country to automobile, needs based on powerful parts industry.Reform Since opening, China's parts industry is fast-developing, and enterprise independent innovation consciousness gradually increases, industry independent research and development capacity It steps up.But all in all, China's parts industry lacks core technology and produces because of capability of independent innovation wretched insufficiency Product, numerous medium and small sized Auto Fittings Enterprises do not obtain radical change or even this in the homogeneous competition situation of industry low side for many years Situation is from domestic development to foreign countries.

During " 12th Five-Year Plan ", many internal and external factors of support China's auto Parts Industry fast development are just occurring deeply Variation, China's auto Parts Industry is faced with domestic automobile industrial restructuring, the new shape of profound change occurs for international trade pattern Gesture.The problem of China's auto Parts Industry capability of independent innovation weakness has had become industry itself and entirely automobile industry The 'bottleneck' restrictions of development.Accelerate to improve parts industry Construction of Independent Innovation Ability, is to push auto Parts Industry knot Structure optimization and upgrading there is an urgent need to, be the key that enhancing China's auto Parts Industry core competitive, construction automobile power Place.

As China enters the ranks of automobile superpower, automobile consumption product gradually come into people's lives, car ownership by Cumulative to add, motor vehicle liquidation amount also rises year by year, contains a large amount of harmful substance during motor vehicle liquidation, if handling without dismantling Environmental and human health impacts can be brought with great harm, available a part of old part by making again after abandoned car dismantling recycling Use value can be realized again by making, and create economic benefit.Develop auto parts and components remanufacturing industry to be gradually valued by people, The development of auto parts and components remanufacturing industry all has society, economy, people's health life 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 mode 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 had been established perfect auto parts and components and have remanufactured development service system, including waste and old component Recovery system, Reverse Logistics System etc., development model and development countermeasure etc. 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, the also increasingly technicalization, elder generation of spare part mould processing technology It evolves, people are more likely to multi-functional, performance is concentrated and carries convenient and fast demand direction.Thus the body development of components becomes Gesture is smaller and smaller, increasingly precise treatment and integrated, i.e., it is towards thin, small, light, while high-precision direction being required to develop.

Sheet Metal Forming Technology saves material and the energy due to having for processing than tradition machinery, high-efficient, wants to operator's technology It asks not high and can be made by various mold applications and be machined be unable to reach product, thus its purposes is more and more wider It is general, therefore many of automobile parts are produced by stamping technology.Some accessories are exclusive due to realize in production process Function, therefore it is complex-shaped, can not successively punch forming, to stamping equipment, more stringent requirements are proposed for this.Therefore, invention vapour Vehicle metal fittings production multiple site punching device, goes solution drawbacks described above necessary.
