钣金加工中的机柜好坏辨别

 如何判断机柜钣金加工的好坏,我们主要看四个方面:看喷漆,钢板、玻璃、配件。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。看机柜表面钣金加工的喷漆,好的机柜所有的钢材都需要喷漆,而且要喷的均匀,这样才能做到很好的防锈和防尘。

Identification of cabinet in sheet metal processing

How to judge the quality of the cabinet sheet metal processing, we mainly look at four aspects: see spray paint, steel plate, glass and accessories. 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. Look at the spray paint on the surface of the cabinet. All the steel in a good cabinet needs to be painted, and it needs to be sprayed evenly. In this way, a good rust proof and dustproof can be achieved.

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,加上机柜里面的配件也很重要,如果机柜带有电缆管理模块使电缆可以直接固定在垂直安装轨内,则再好不过。无论哪种情况,机柜内部的上壁和侧壁应当有足够多的固定环(来保护电缆),也可以通过把机柜底板上抬,以便下面走线。还有一些用来固定机架的螺丝、螺母等,也要足量。这样可以避免日后扩展而带来配件不足的麻烦。
Steel bar cabinet is a structural form of steel section and steel plate bending combined welding or steel profile welding and aluminum alloy castings. It can meet the general ship conditions. But because of the deformation of steel sections, the accessories inside the cabinet are also very important. If the cabinet has a cable management module, the cable can be used directly. It is better to be fixed in the vertical installation rail. In either case, the upper and side walls of the cabinet should have enough fixed ring (to protect the cable), and can also be carried on the floor of the cabinet for the following line. There are also some screws and nuts for fixing the rack. This can avoid future expansion and bring inconvenience to accessories.

机柜焊接时变形大,无法消除参与应力,其精度差。看钢板的厚度,只要用手指敲一下就知道钢板的厚薄了,还有机柜内部的支架也是粗点的好,因为有时候里面装的设备比较重,要是太细的话看就承受不了设备的重量了。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。看玻璃,玻璃也要厚一点,特别要注意看玻璃的周边有没有裂痕,如果有的话建议还是别要,还要看玻璃是否棘手。

When the cabinet is welded, the deformation is large and the participation stress can not be eliminated, and its accuracy is poor. Look at the thickness of the steel plate, as long as you use your fingers to know the thickness of the steel plate, and the inside of the cabinet is also a good point, because sometimes the equipment is heavy, if it is too thin, you can't bear the weight of the equipment. 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. Look at the glass, the glass should be a little thicker, especially to see if there is any cracks around the glass. If there are some suggestions, do not want it, and see if the glass is tough.
