1、建立、实施和保持环境管理体系,钣金加工依据公司活动、产品和服务对环境产生的影响,制定、推进和评审环境目标和指标;

2、严格遵守国家、地方环境法律法规及其他要求;

3、实施清洁生产,科学做好节能、降耗、减排工作,预防污染,持续改进;

4、开展环境教育活动,提高全员环保意识和能力;

5、与相关方充分合作,共同创建更美好的环境。

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钣金加工,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. CNC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。

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.

⑤. 锯床:主要用下铝型材、方管、图管、圆棒料之类,成本低,精度低。

2. 钳工:沉孔、攻丝、扩孔、钻孔沉孔角度一般120℃,用于拉铆钉,90℃用于沉头螺钉,攻丝英制底孔。

3. 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。

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。

5. 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。

6. 折弯;折弯就是将2D的平板件,折成功D的零件。其加工需要有折床及相应折弯模具完成,它也有一定折弯顺序,其原则是对下一刀不产生干涉的先折,会产生干涉的后折。

1, the establishment, implementation and maintenance of environmental management system, sheet metal processing based on the impact of the company activities, products and services on the environment, to formulate, promote and review environmental objectives and indicators;

2, strictly abide by national and local environmental laws and regulations and other requirements.

3, implement cleaner production, and do well in energy conservation, consumption reduction, emission reduction, pollution prevention and continuous improvement.

4, carry out environmental education activities to improve the awareness and ability of environmental protection.

5, cooperate with relevant parties to create a better environment.

The difference of sheet metal structure and process can be different, but the total number of sheet metal parts is not more than the following points:

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

Scissors: it is a simple sheet metal sheet metal cutting with cutting bed cutting material. It is mainly prepared for die blanking forming, the cost is low, the precision is less than 0.2, but it can only be processed without holes and no cutting corners of the strip or block material.

(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).CNC numerical control blanking, NC is the first to write the numerical control process program, using the 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 on the flat plate, but its structure is subject to the tool structure, low cost, precision At 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..

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

2. fitter: deep hole, tapping, reaming, drill hole sinking angle generally 120 degrees, for pulling rivet, 90 degrees for countersunk screw, tapping the British bottom hole.

3. flanging: also called hole and hole, that is to draw a slightly larger hole on a smaller base hole, and then tapping, mainly using sheet metal processing with thin plate thickness, increasing its strength and number of threads to avoid sliding teeth, generally used for thin plate thickness, and the shallow flanging of the hole Zhou Zhengchang, the thickness is basically unchanged, allowing thickness to be 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.

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.

5. 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.

6. bending; bending is to fold the 2D flat parts into D parts. Its processing requires a folding bed and a corresponding bending die. It also has a certain bending order. The principle is that the next knife does not interfere with the first fold, resulting in a back break of interference.
