钣金构件和钣金加工材料的选用

2018-06-08 15:12:28 常州亿创钣金加工厂 阅读

钣金加工一般用到的材料有冷轧板(SPCC)、热轧板(SHCC)、镀锌板(SECC、SGCC),铜(CU)黄铜、紫铜、铍铜,铝板(6061、6063、硬铝等),铝型材,不锈钢(镜面、拉丝面、雾面),根据产品作用不同,选用材料不同,一般需从产品其用途及成本上来考虑。钣金设备基本上就是数控冲床,折弯机,剪钣机,刨槽机,激光切割机这些设备了,作用的话你看设备名字应该就知道用途了,价格的话国产跟国外的差距很大,具体价格可以去再去咨询一下,激光切割机是不能少的,有这个设备对你产品的质量也很好控制。
The materials used in sheet metal processing are cold rolled plate (SPCC), hot rolled plate (SHCC), galvanized sheet (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum sheet (6061, 6063, hard aluminum, etc.), aluminum profiles, stainless steel (mirror, drawing surface, fog surface), according to the different products, the selection of materials is different, generally needed. Consider the use and cost of the product. Sheet metal equipment is basically CNC punch press, bending machine, shear plate machine, planer machine, laser cutting machine, such equipment, if the role of the device you see the name of the equipment should know the use, the price of the gap between domestic and foreign great, the specific price can go to consult again, laser cutting machine is not less, there is this The equipment is well controlled for the quality of your product.

1.不锈钢;主要用不作任何表面处理,、成本高。

2.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。

3.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。

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。

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

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

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

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.

根据钣金件结构的差异,工艺流程可各不相同,但总的不超过以下几点。

1、下料:下料方式有各种,主要有以下几种方式

①. 剪床:是利用剪床剪切条料简单料件,它主要是为模具落料成形准备加工,成本低,精度低于0.2,但只能加工无孔无切角的条料或块料。

②. 冲床:是利用冲床分一步或多步在板材上将零件展开后的平板件冲裁成形各种形状料件,其优点是耗费工时短,效率高,精度高,成本低,适用大批量生产,但要设计模具。

③. NC数控下料,NC下料时首先要编写数控加工程式,利用编程软件,将绘制的展开图编写成NC数拉加工机床可识别的程式,让其根据这些程式一步一刀在平板上冲裁各构形状平板件,成本低,精度于0.15。

④. 镭射下料,是利用激光切割方式,在大平板上将其平板的结构形状切割出来,同NC下料一样需编写镭射程式,它可下各种复杂形状的平板件,成本高,精度于0.1.

According to the difference of sheet metal structure, the process flow can be different, but the total does not exceed the following points.

1. Blanking: there are various ways of cutting materials, mainly in the following ways.

Scissors: it is a simple material for cutting the strip by cutting the cutting bed. It is mainly prepared for the molding of die blanking. The cost is low and the precision is less than 0.2.

(2). Punching machine: it is a kind of shape material that can be blanked out by one or more steps on the plate. The advantage is that it takes short time, high efficiency, high precision and low cost, and it is suitable for mass production, but it is necessary to design a mold.

(3).NC numerical control blanking, NC is the first to write numerical control process program, using programming software, the drawing of the expansion map is written into the NC number drawing machine tool can be identified, so that the program according to these programs one step on the flat plate blanking plate, low cost, precision in 0.15.

(4). Laser cutting is used to cut the structure of the flat plate on a large plate by laser cutting. It needs to write a laser program like the NC material. It can lower the complex shape of the flat plate, and the cost is high and the precision is in the 0.1..
