优质钣金件的加工条件和工艺介绍

钣金件就是薄板五金件,也就是数控冲床对外加工可以通过冲压,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。  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、天圆地方、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。
Sheet metal parts are sheet metal parts, that is, CNC punching machine can be processed by stamping, bending, drawing and other means. A general definition is the parts with constant thickness during the process. Correspondingly, casting parts, forging parts, machined parts and so on. 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, round 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 the parts of the same thickness in the process. The relative is the casting parts, the forging parts, the machined parts, etc., for example, the iron shell outside the car is the sheet metal parts, and some cupboards made of stainless steel. It is also a sheet metal piece.

五金加工厂认为钣金加工通常,钣金加工最重要的三个步骤是剪、冲/切、折。

优质钣金件的特点:

1.劣质钣金件的平整度需作较大的调校

2.一级的钣金件与原车的间隙差只存在0.3mm

3.劣质钣金件的孔位会无法对齐,需重新钻孔

4.优质钣金件需采用机械生产,其焊点和切边平整,无粗糙毛边

5.优质钣金件很讲究烤漆工艺,要求分量均匀、附着力强和良好的防水、防氧化性

钣金加工的工艺流程跟材料

1.不锈钢;主要用不作任何表面处理,、成本高。

2.冷轧板SPCC,主要用电镀和烤漆件,成本低,易成型,材料厚度≤3.2mm。

3.铝型材;截面结构复杂的料件,大量用于各种插箱中。表面处理同铝板。

4.铜;主要用导电作用料件,其表面处理是镀镍、镀铬,或不作处理,成本高。

5.热轧板SHCC,材料T≥3.0mm ,也是用电镀,烤漆件,成本低,但难成型,主要用平板件。

6.镀锌板SECC、SGCC。SECC电解板分N料、P料,N料主要不作表面处理,成本高,P料用于喷涂件。

7.铝板;一般用表面铬酸盐(J11-A),氧化(导电氧化,化学氧化),成本高,有镀银,镀镍。

优质钣金件是如何加工的?

钣金加工有时也作扳金加工,这个词来源于英文platemetal,一般是将一些金属薄板通过手工或模具冲压使其产生塑性变形,形成所希望的形状和尺寸,并可进一步通过焊接或少量的机械加工形成更复杂的零件,比如家庭中常用的烟囱,铁皮炉,还有汽车外壳都是板金件。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。


The hardware processing plant thinks that the most important three steps in sheet metal processing are cutting, punching, cutting and folding.

The features of high quality sheet metal parts:

1. the flatness of the shoddy sheet metal parts needs to be adjusted to a greater degree

2. there is only 0.3mm gap between the first grade sheet metal parts and the original vehicle.

3. the hole position of poor quality sheet metal parts can not be aligned, and need to be re drilled.

4. high quality sheet metal parts need to be manufactured by machine. Their solder joints and trimming are smooth without rough edges.

5. high quality sheet metal parts are very particular about baking process. They require uniform weight, strong adhesion and good waterproof and oxidation resistance.

Process and material of sheet metal processing

1. stainless steel; it is mainly used without any surface treatment and high cost.

2. cold rolled plate SPCC, mainly used in electroplating and baking parts, low cost, easy to shape, material thickness less than 3.2mm.

3. aluminum profile, complex section material, used in various inserts. The surface is treated with the same aluminum plate.

4. copper; mainly used for conductive parts, the surface treatment is nickel plated, chrome plated, or not processed, and the cost is high.

5. hot-rolled sheet SHCC, material T or more 3.0mm, is also used electroplating, baking paint parts, low cost, but difficult to shape, mainly using flat parts.

6. galvanized sheet SECC, SGCC. SECC electrolysis plate is divided into N material and P material. N material is mainly used for surface treatment and high cost. P material is used for spraying parts.

7. aluminum plate; generally used surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plated, nickel plated.

How are the high quality sheet metal parts processed?

The word sheet metal processing is sometimes made of gold, which is derived from the English platemetal. Generally, some metal sheets are made by hand or die punching to produce plastic deformation, forming the desired shape and size, and further forming more complex parts by welding or a small amount of mechanical processing, such as the common use in the family. The chimney, the iron stove, and the automobile shell are all pieces of sheet metal. 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.
