如何做好不銹鋼機柜的鈑金加工

2018-08-15 19:04:38 常州億創能源科技有限公司 閱讀

做好不銹鋼鈑金加工的零部件檢驗標準。雖然不銹鋼鈑金機箱機柜各項指標要求工藝有所不同,但是不銹鋼鈑金加工的零部件檢驗標準基本一致,具體如下:1、零件按圖紙正確加工。一切棱邊、鋒芒均應倒鈍,毛刺、飛邊的高度不得超越0.2mm,原則上以不劃手為原則。

Do the parts inspection standard for stainless steel sheet metal. Although the stainless steel sheet metal chassis cabinet requirements of various indicators are different, but the stainless steel sheet metal processing parts inspection standards are basically the same, as follows: 1, parts according to the correct drawing processing. All edges and sharp edges should be obtuse, burrs and flying edges should not exceed the height of 0.2 mm, in principle, the principle of non-stroke.

2、一切導電件一概采用GB5585-85規則的銅母排系列或純銅板制成,外表鍍涂按圖紙請求制造。需折彎的,折彎前應作退火處理,且折彎圓角半徑應大于板料厚度,避免損傷內部組織及開裂。緊固連接部位的觸摸外表請求校平。

2. All conductive parts are made of GB5585-85 copper master row series or pure copper plate. The surface is plated according to the drawing requirements.  If bending is required, annealing should be done before bending, and the radius of bending fillet should be greater than the thickness of sheet metal to avoid damage to internal structure and cracking. The touch surface of the fastening part is asked for leveling.

3、絕緣件按圖紙選用的絕緣材料,環氧板或環氧棒應作浸絕緣漆,烘干處理。安裝后的機柜正負級銅排隊機架的電阻絕緣值100M(在環境溫度為25℃-2℃),相對濕度為90%。電壓為直流500V時)。

3. The insulation material selected according to the drawings, the epoxy board or the epoxy rod should be dipped in the insulating paint and dried. After installation, the resistance insulation value of the positive and negative copper queuing frame of the cabinet is 100M (in the ambient temperature of 25 ~2 ~C), and the relative humidity is 90%. When the voltage is DC 500V.

4、壓鉚螺母及螺釘須壓鉚結實,按請求的螺釘螺母固力矩規范檢驗,不能有松脫景象。零件在噴涂過程中維護螺紋,對于鍍涂過程中引起的堵塞,應從頭攻絲整復。螺紋孔應無滑絲,斷扣景象,螺釘應能順暢旋入且松緊適度。

4. Pressure riveting nuts and screws must be riveted and sturdy, according to the requirements of the screw nut fixation torque specifications inspection, can not loose the scene. Parts in the spraying process to maintain threads, for the coating process caused by clogging, should be tapped from scratch. Thread holes should be smooth and broken. The screws should be able to be screwed smoothly and moderately.

5、堅固件什物應契合選用的規范或圖樣。螺釘、螺栓、螺母、平墊、彈墊外表處理應與圖紙請求相符。螺釘斷扣景象,螺釘應能順暢旋入且松緊適度。

5, solid objects should conform to the specifications or patterns used. The surface treatment of screws, bolts, nuts, flat pads and pad shall conform to the drawing request. The screw is broken, and the screws should be able to be screwed smoothly and moderately.

二、做好不銹鋼機箱機柜鈑金加工的設計工作。

Two, do a good job in the design of sheet metal processing for stainless steel cabinet.

1、內置安裝板可前后移動,使內部安裝更加靈活;

1, the built-in mounting plate can move back and forth, making the internal installation more flexible.

2、前后開門及操作面蓋板可打開,方便安裝:

2. Front and rear door opening and operation cover can be opened to facilitate installation.

3、槽型箱邊與門體聚氨指發泡密封膠條確保了柜體的防護等級;

3. Groove box side and door body polyamine finger foaming sealant ensure the protection level of the cabinet.

4、門安裝嵌條:已打好裝配孔的嵌條焊接于門板的兩側和操作面蓋板的上下位置,并借助于安裝條,使門板及蓋板的安裝更加靈活,走線更加方便;

4. Door mounting inserts: the inserts with assembled holes are welded on both sides of the door plate and the upper and lower positions of the cover plate of the operation surface, and the installation of the door plate and the cover plate is more flexible and the alignment is more convenient by means of the installation strips.

5、原裝進口的操作面蓋板液壓支撐,大大提升了柜體檔次,更好的體現了柜體的人性化設計。

5. The hydraulic support of the original imported operation surface cover plate greatly improves the class of the cabinet and better reflects the humanized design of the cabinet.

三、預防好鈑金機箱某些缺陷的滋生。

Three, prevent the development of certain defects in the sheet metal chassis.

在一些質量不是特別好的鈑金機箱機柜的表面常會見到基層有雜物、色差嚴重、涂覆層脫落、漆流、積粉等種種狀況,其實是由于鈑金機箱機柜在鈑金加工過程中的一些失誤造成的;具體如下:

On the surface of some sheet metal cabinet cabinets which are not of very good quality, we often see various conditions such as impurities, serious color difference, coating shedding, lacquer flow and powder accumulation on the base course, which are actually caused by some mistakes in the sheet metal processing of the sheet metal cabinet cabinet.

1、底層有雜物是指在外表處理時基材外表沒有處理潔凈發生的缺點,它是發生涂覆層掉落的首要因素。

1. Substrate impurities refer to the shortcomings of substrate surface not treated and cleaned during surface treatment, which is the primary factor of coating dropping.

2、涂覆層掉落首要是涂覆層與基材的結合力不夠,檢查結合力的首要手段有沖擊實驗和劃格實驗。

2. Coating layer dropping is mainly due to insufficient adhesion between coating and substrate. The primary means of checking adhesion are impact test and scratch test.

3、露基材是指外表沒有涂覆層,首要發生因素是漏噴、大面積劃傷。

3, exposed substrate is the appearance of no coating, the main factor is leakage spray, large area scratches.

4、外表劃傷發生的因素比較復雜且貫穿商品出產的全部進程,但大致可分為兩類:一是商品在加工時發生的劃痕;二是在出產進程中物流發生的劃痕。

4. The factors of appearance scratch are complicated and run through the whole process of commodity production, but they can be roughly divided into two types: one is the scratch of commodity in processing; the other is the scratch of logistics in the process of production.

5、漆流、積粉發生的原理大致適當,僅僅漆流是噴漆時發生,積粉是噴塑時發生,皆因噴涂量過大、過厚而發生缺點。

5. The principle of lacquer flow and powder accumulation is generally appropriate. Only lacquer flow occurs when spraying, and powder accumulation occurs when spraying. Both of them have shortcomings because of too much and too thick spraying.
