钣金加工是什么,钣金加工行业的现状浅析

精密钣金加工行业的现状 整体来说,近几年来,钣金行业可谓发展迅猛。金属板材加工就叫钣金加工。具体譬如利用板材制作烟囱、铁桶、油箱油壶、通风管道、弯头大小头、天园地方、漏斗形等,主要工序是剪切、折弯扣边、弯曲成型、焊接、铆接等,需要一定几何知识。

钣金件就是薄板五金件,也就是可以通过冲压,弯曲,拉伸等手段来加工的零件,一个大体的定义就是:在加工过程中厚度不变的零件. 相对应的是铸造件,锻压件,机械加工零件等,比如说汽车的外面的铁壳就是钣金件,不锈钢做的一些橱具也是钣金件。

钣金加工一般用到的材料有冷轧板(SPCC)、镀锌板(SECC)、铜板、铝板、不锈钢板、铝材等.其作用各不相同.至于如何选用,一般需从其用途及成本上来考虑。而这主要有如下几方面原因,生产能力需求提高。中国越来越成为国际加工制造中心,加上国外投资的不断增加。

钣金加工冲孔精度一般在±0.1mm左右,折弯精度一般可以达到±0.5mm,因此相对于钣金加工来说,精度低得多;利润高,如冲压一般可以达到30%左右,而激光切割则可以达到50%甚至更多。

金属加工的能力需求不断加大,而金属加工行业中的电器控制箱、机器外壳等一般来说都是钣金件,所以钣金加工能力需求也不断提高,加工精度要求低,上手容易。

钣金加工而言,精度在几丝是很司空见惯的事,而工艺的复杂性也比较高,甚至有些零件工序达到几十道之多。所以钣金加工企业通常需要各种各样的机械设备以满足不同工艺要求。

As a whole, the sheet metal industry has developed rapidly in recent years. Sheet metal processing is called sheet metal processing. For example, making use of plate to make chimneys, iron buckets, oil tank oil pot, ventilation pipe, big head of elbow, Tianyuan place, funnel shape and so on. The main working procedure is cutting, bending and buckle edge, bending forming, welding, riveting and so on. It needs certain geometric knowledge.

Sheet metal parts are sheet metal parts, that is, parts that can be processed by means of stamping, bending and stretching. A general definition is that parts with constant thickness in the process are casting parts, forgings, machined parts, etc., for example, the iron shell outside the steam car is a sheet metal piece, some stainless steel is made. The cabinet is also a sheet metal.

The materials used in sheet metal processing are cold rolled plate (SPCC), galvanized sheet (SECC), copper plate, aluminum plate, stainless steel plate, aluminum material and so on. The function of the sheet metal is different. As for how to choose, it should be considered from its use and cost. This is mainly due to the following reasons: the increase of production capacity. China has increasingly become an international manufacturing and manufacturing center, coupled with increasing foreign investment.

The precision of the sheet metal processing punching is about + 0.1mm, and the bending precision can generally reach to + 0.5mm. Therefore, compared with the sheet metal processing, the precision is much lower and the profit is high, such as the stamping can reach about 30%, and the laser cutting can reach 50% or even more.

The ability demand of metal processing is increasing, and the electrical control box and machine shell in the metal processing industry are generally sheet metal parts, so the demand for sheet metal processing ability is also increasing, the processing precision is low, and the upper hand is easy.

As far as sheet metal processing is concerned, accuracy is very common in several threads, and the complexity of the process is relatively high. Even some parts work in dozens of ways. Therefore, sheet metal processing enterprises usually need a variety of mechanical equipment to meet different technological requirements.
