钣金加工件有哪些加工流程呢?

你们知道钣金加工件有哪些加工流程呢?其实我知道的也不是很多,所以现在由机箱机柜钣金加工来告诉大家:
1、翻边:又叫抽孔、翻孔,就是在一个较小的基孔上抽成一个稍大的孔,再攻丝,主要用板厚比较薄的钣金加工,增加其强度和螺纹圈数,避免滑牙,一般用于板厚比较薄,其孔周正常的浅翻边,厚度基本没有变化,允许有厚度的变薄30-40%时,可得到比正常翻边高度大高40-60%的高度,用挤薄50%时,可得最大的翻边高度,当板厚较大时,如2.0、2.5等以上的板厚,便可直接攻丝。

2. 压铆:压铆就本公司而言,主要有压铆螺母、螺钉、松不脱等,其是通过液压压铆机或冲床来完成操作,将其铆接到钣金件上,还有涨铆方式,需注意方向性。

3.下料:下料方式有各种,主要有以下几种方式①. 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,但其结构 受刀具结构所至,成本低,精度于0.15。

②.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。

③.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。

④.锯床:主要用下铝型材、方管、图管、圆棒料之类,成本低,精度低。

⑤.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.

4.冲床:是利用模具成形的加工工序,一般冲床加工的有冲孔、切角、落料、冲凸包(凸点),冲撕裂、抽孔、成形等加工方式,其加工需要有相应的模具来完成操作,如冲孔落料模、凸包模、撕裂模、抽孔模、成型模等,操作主要注意位置,方向性。

Do you know the processing flow of sheet metal parts? Actually, I don't know much about it, so now I'm going to tell you from the cabinet's sheet metal processing.

1, flanging: also called hole, turn hole, that is to draw a slightly larger hole on a small base hole, then tapping, mainly using thin plate thickness of sheet metal processing, increase its strength and thread number, avoid sliding teeth, generally used for thin plate thickness, its hole Zhou Zhengchang shallow edge, thickness basically unchanged, allow thick. When the degree of 30-40% is thinner, the height of 40-60% higher than the normal flanging height can be obtained. The maximum flanging height can be obtained when it is thinned by 50%. When the thickness of the plate is larger, the thickness of the plate, such as 2, 2.5, etc., can be tapped directly.

2. pressure rivet: pressure riveting on the company, the main pressure riveting nuts, screws, loose and so on, it is through the hydraulic pressure riveting machine or punch to complete the operation, it is riveted to sheet metal parts, there is also rising riveting way, need to pay attention to the direction.

3. blanking: there are all kinds of blanking methods, mainly in the following ways:.NC numerical control. NC is the first to write numerical control program. Using programming software, the drawing is written into a program that can be identified by the NC number drawing machine tool. However, its structure is reduced by the tool structure, the cost is low, and the accuracy is 0.15.

2. Shearing machine: it is a simple material for cutting the strip by cutting the cutting bed. It is mainly prepared for the die blanking forming, the cost is low, the precision is less than 0.2, but it can only process the strip without the hole and no cutting angle.

(3). Punching machine: it is a kind of shape material that can be blanked out of plate parts with one or more steps on the plate. Its advantages are short time, high efficiency, high precision and low cost. It is suitable for mass production, but it is necessary to design a mold.

4. Sawing machine: mainly use lower aluminum profile, square tube, picture tube, round bar material and so on, with low cost and low precision.

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, with high cost and the precision of 0.1..

4. punching machine: using die forming process, the general punching machine has punching, cutting angle, blanking, punching bulge (Bump), punching and tearing, drawing holes, forming and other processing methods. Its processing needs corresponding die to complete operation, such as punching die, punch die, tearing die, drawing die, molding mould, etc. Pay attention to the position and direction.
