铝车身维修操作注意事项

来源:http://www.jnrunao.com/ 日期:2020-04-27 发布人:admin
  随着汽车技术的飞速发展,汽车制造商们对汽车的结构设计、制造技术和材料选择做了大量的研究,希望能开发出安全、可靠、节能、的新型汽车。在正常情况下,车身重量会消耗70%左右的燃料,所以降低汽车燃料消耗的首要问题是如何使汽车轻量化。使汽车从材料上轻量化,不仅可以减轻车身重量,提高设备的质量,减轻发动机的负荷,还可以大大减少底盘部件所受的合力,使车辆的操控性、经济性更加优异。
  With the rapid development of automobile technology, automobile manufacturers have done a lot of research on the structure design, manufacturing technology and material selection of automobile, hoping to develop a new type of safe, reliable, energy-saving and environmental protection automobile. Under normal circumstances, the body weight will consume about 70% of the fuel, so the first problem to reduce the fuel consumption is how to make the car lightweight. To lighten the vehicle from the material can not only reduce the weight of the body, improve the quality of the equipment, reduce the load of the engine, but also greatly reduce the resultant force of the chassis components, making the vehicle's handling and economy more excellent.

  和“轻金属”说的铝金属,因为它的质量很轻,耐磨、耐腐蚀、弹性好,刚度和比强度高,抗冲击性能好,加工和成形良好,重现性高的特点,使汽车轻量化成为材料。铝合金车身也因其低能耗、安全舒适和较强的相对承载能力而受到青睐。
  And "light metal" said aluminum metal, because its quality is very light, wear-resistant, corrosion-resistant, elastic, high stiffness and specific strength, good impact resistance, good processing and forming, high reproducibility, so that the automobile lightweight become the first choice of materials. Aluminum alloy body is also favored for its low energy consumption, safety and comfort, and strong relative bearing capacity.
  1、铝车身特殊气体保护焊机及形状维修机
  1. Special gas shielded welding machine and shape maintenance machine for aluminum body
  由于铝的熔点低,易变形,焊接要求低电流,所以必须使用专用的铝车身气体保护焊机。形状修护机也不能像普通的形状修护机那样点击和拉伸,只能使用一种特殊的铝制车身形状修护机焊接介子钉,使用介子钉拉伸器进行拉伸。
  Because the melting point of aluminum is low, it is easy to deform, and the welding requires low current, so it is necessary to use a special gas shielded welding machine for aluminum body. The shape repair machine can't click and stretch like the ordinary shape repair machine. It can only use a special aluminum body shape repair machine to weld the meson nails, and use the meson nail stretcher to stretch.

  2、专用铝合金车身维护工具,强力铆接枪
  2. Special aluminum alloy body maintenance tool, powerful riveting gun
  与传统的事故车维修不同,铝车身的维修大多采用铆接维修方法,其中必须有较强的铆接枪。维修时必须专用铝身工具,不能与维修钢身工具混用。钢体修复后,工具上会留下铁屑。如果是修复铝体,铁屑会嵌入铝表面,对铝造成腐蚀。
  Different from the traditional accident vehicle maintenance, the aluminum body maintenance mostly adopts riveting maintenance method, in which there must be a strong riveting gun. Special aluminum body tools must be used for maintenance, and cannot be mixed with steel body tools for maintenance. After the steel body is repaired, iron chips will be left on the tool. If the aluminum body is repaired, the iron chips will be embedded in the aluminum surface, causing corrosion to the aluminum.
  3.防爆除尘除尘系统
  3. Explosion proof dedusting and dedusting system
  在抛光铝体的过程中,会产生大量的铝粉,铝粉不仅对人体有害,而且易燃易爆,所以应该有防爆除尘系统及时吸收铝粉。
  In the process of polishing aluminum body, a lot of aluminum powder will be produced. Aluminum powder is not only harmful to human body, but also flammable and explosive, so there should be an explosion-proof dust removal system to absorb aluminum powder in time.
  4. 独立的维护空间
  4. Independent maintenance space
  由于对铝车身维修技术的严格要求,为保证汽车维修质量和维修操作安全,避免铝粉对车间的污染和爆炸,需设立单独的铝车身维修站。另外,对铝件的维修人员进行培训,掌握铝件的维修技术,如何定位拉伸、焊接、铆接、粘接。
  Due to the strict requirements of aluminum body maintenance technology, in order to ensure the quality of vehicle maintenance and operation safety, and avoid the pollution and explosion of aluminum powder to the workshop, it is necessary to set up a separate aluminum body maintenance station. In addition, carry out professional training for the maintenance personnel of aluminum parts, master the maintenance technology of aluminum parts, and how to position, stretch, weld, rivet and bond.

  维修操作注意事项
  Precautions for maintenance operation
  1. 铝合金板局部拉伸性能不佳,容易产生裂纹。例如,由于复杂的发动机罩内板的形状,为了提高身体的拉伸变形性能在制造、使用高强度铝合金,延伸率已超过30%,所以在维护以确保尽可能不会改变形状,为了避免裂缝。
  1. The local tensile property of aluminum alloy plate is poor, which is easy to produce cracks. For example, due to the complex shape of the engine hood inner plate, in order to improve the tensile deformation performance of the body, high-strength aluminum alloy is manufactured and used, and the elongation has exceeded 30%. Therefore, maintenance is carried out to ensure that the shape is not changed as much as possible, and to avoid cracks.
  2. 尺寸精度不易把握,回弹难以控制。在维护过程中尽量采用应力释放法,使其稳定,避免回弹等二次变形。
  2. The size accuracy is not easy to grasp and the rebound is difficult to control. In the process of maintenance, stress release method should be used as much as possible to make it stable and avoid secondary deformation such as rebound.
  3,因为铝比钢更温和的维护碰撞和各种粉尘粘附和其他原因将导致零件表面擦伤,划痕和其他缺陷,所以清洁模具,设备清洁、环境灰尘、空气污染和其他方面的相应措施,确保零件的完整性。
  3. Because the milder maintenance collision of aluminum than steel and various dust adhesion and other reasons will lead to parts surface scratch, scratch and other defects, so clean the mold, equipment cleaning, environmental dust, air pollution and other corresponding measures to ensure the integrity of parts.
