如今的钣金加工行业竞争不可谓不激烈,大家在加工各种钣金件的时候务必要以客户要求为第一位,以客户满意为标准,运用好材料,施展好工艺。

对于钣金加工行业来说,同样需要因材施工。

目前我国铝型材市场按应用领域划分主要两种:一是建筑铝型材,建筑铝型材主要用于各类民用及商用建筑领域;二是工业铝型材,工业铝型材则主要应用于除建筑领域外的其他工业领域,其中运输和机电设备是工业铝型材的主要消费领域。

就目前来看,国内市场上,建筑铝型材市场比例高于工业铝型材,因为建筑行业仍是我国铝型材主要消费领域,而且在在消费市场需求占比在60%以上。

大家通常遇到的冷轧钢板、钢型材、铸铝型等材料,他们的钣金加工方式都大不相同,下面跟大家分析一下这三者的加工特性:

现在的机柜原材料用的最多的就是冷轧钢板了。冷轧钢板在常温下是不产生氧化反应的,所以表面质量好,尺寸的精度也高,再加上退火处理其机械性能和工艺性能都优于热轧薄钢板。

钢型材机柜,是采用将钢型材与钢板折弯组合焊接或钢型材焊接与铝合金铸件组装的结构形式,可以满足一般舰用条件,但由于钢型材存在变形问题,加上机柜焊接时变形大,无法消除参与应力,其精度差。

铸铝机柜,是用铸铝或分片加工铸造而成,它具有很好的抗压抗扭钢度,抗震和抗冲击及散热性能,此外,机柜表面加工质量好,外形美观,有尺寸精度高的优点。但在重量上要比其他类型机柜略重,且制造成本高、生产周期长。所以现在最常用的钣金加工,就是冷轧钢板这种材质的机柜了。但是如果从消费结构的变化来看,工业铝型材的需求量正悄然上升,工业领域对铝型材的需求量增速近年来明显加快,消费占比也逐年提高,由2008年的31%上升到接近37%。其中运输领域对铝型材的消费增长最为显着,尤其是轨道交通的建设,成为拉动工业铝型材需求的重要的力量。

Nowadays, the competition of sheet metal processing industry is not very fierce. When we are processing all kinds of sheet metal parts, we must take customers as the first, the customer satisfaction as the standard, the use of good materials and the good process.

For sheet metal processing industry, construction is also needed.

At present, there are two main types of aluminum profile market in China: one is the building aluminum profiles, and the aluminum profiles are mainly used in various civil and commercial buildings; two are industrial aluminum profiles, and industrial aluminum materials are mainly used in other industrial fields except the construction field, of which the transportation and Mechanical and electrical equipment are industrial aluminum profiles. Major consumption areas.

At present, the market proportion of aluminum profiles in the domestic market is higher than that of industrial aluminum profiles, because the construction industry is still the main consumption field of aluminum profiles in China, and the demand for the consumption market is more than 60%.

We usually meet the cold rolled steel, steel, cast aluminum and other materials, their sheet metal processing methods are very different, following the analysis of the three of the processing characteristics:

The most used materials for cabinet now are cold-rolled steel plates. The cold rolled steel plate has no oxidation reaction at normal temperature, so the surface quality is good, the precision of the size is high, and the mechanical and technological properties of the annealing treatment are better than that of the hot rolled sheet.

Steel bar cabinet is a structural form of assembling steel section and steel plate bending combined welding or steel section welding with aluminum alloy castings. It can meet the general ship conditions. However, because of the deformation of steel sections, the deformation of the cabinet is large and the participation stress can not be eliminated, and its precision is poor.

Cast aluminum cabinet is made of cast aluminum or piecewise processing. It has good compression and torsion resistance, anti-seismic and impact resistance and heat dissipation. In addition, the surface processing quality of the cabinet is good, the appearance is beautiful, and the dimension precision is high. But the weight is slightly heavier than other types of cabinet, and the manufacturing cost is high and the production cycle is long. So now the most commonly used sheet metal processing is the cold rolled steel plate of this material cabinet. However, if the demand for industrial aluminum profiles is rising quietly from the change of consumption structure, the demand for aluminum profiles in industrial fields has accelerated in recent years, and the consumption ratio has increased year by year, up from 31% in 2008 to close to 37%. Among them, the consumption of aluminum profile is the most significant in the transportation field, especially the construction of rail transit, which has become an important force to stimulate the demand of industrial aluminum profile.
