1.簡(jiǎn)單成型彎曲法
1. Simple forming bending method
平的薄板通過(guò)適當(dāng)?shù)那懈钚纬蓮澢缌鳎ㄟ^(guò)凹凸刀具的沖壓形成各種角度的彎曲面,將各個(gè)彎曲面包圍在不同的箱子里,接縫通過(guò)全焊接、點(diǎn)焊、角焊或邊焊的方法連接。
The flat sheet forms bending overflow through appropriate cutting, forms bending surfaces at various angles through the stamping of concave convex cutter, surrounds each bending bread in different boxes, and the joints are connected by full welding, spot welding, fillet welding or edge welding.
2.模具沖壓法
2. Die stamping method
對(duì)于機(jī)箱機(jī)柜復(fù)雜結(jié)構(gòu)的加工,傳統(tǒng)的加工方法和工藝是無(wú)法實(shí)現(xiàn)的。這就需要制造五金模具,通過(guò)落料模下料、成型模沖壓成型形狀簡(jiǎn)單、體積小的機(jī)柜可一次沖壓成型;形狀復(fù)雜、體積大的箱體,可分割成若干個(gè)零件分別沖壓成型,再通過(guò)拼焊或螺栓連接、裝配等方法來(lái)實(shí)現(xiàn)。
For the processing of complex structure of chassis and cabinet, the traditional processing methods and processes can not be realized. This requires the manufacture of hardware molds. The cabinet with simple shape and small volume can be pressed and formed at one time through blanking die and forming die; The box with complex shape and large volume can be divided into several parts, which can be stamped and formed respectively, and then realized by spell welding, bolt connection, assembly and other methods.
3.分塊拼焊補(bǔ)絲法
3. Block welding repair wire method
對(duì)于體積大、形狀復(fù)雜的機(jī)箱機(jī)柜,采用分塊加工、然后在拼焊、補(bǔ)絲的加方法是節(jié)省加工成本的很好方法。分塊加工注意分割的工藝原則保證分割加工后拼接后的美觀性和強(qiáng)度,主要分割的原則有:a)大分小的分割原則:就是將體積較大的零件分割成若干體積(面積)較小的零件,進(jìn)行拼接而成。b)不同形狀特征的分割原則:就是按照不同的形狀特征的構(gòu)成單元,分割成若干零件,分別加工,Zui后拼接而成。c)封閉形狀特征的分割原則:對(duì)于封閉形狀特征的零件,主要從展開(kāi)缺料邊緣處分割,也可以中部分割。d)相交特征的分割原則:對(duì)于相交特征的零件,盡量沿相交線進(jìn)行分割,加工接連后,除焊接方式聯(lián)接外,還有多種不同的聯(lián)接方式,接縫因與分割線重合而美觀,看不出分割缺陷。
For the cabinet with large volume and complex shape, it is a good way to save the processing cost by using the method of block processing, then splicing welding and wire repair. In block processing, pay attention to the process principle of segmentation to ensure the beauty and strength after splicing. The main segmentation principles are: a) the principle of large division and small Division: that is, the parts with large volume are divided into several parts with small volume (area) and spliced. b) Segmentation principle of different shape features: it is divided into several parts according to the constituent units of different shape features, processed separately, and spliced after Zui. c) Segmentation principle of closed shape features: for parts with closed shape features, they are mainly segmented from the edge of material shortage, or from the middle. d) Segmentation principle of intersecting features: parts with intersecting features shall be segmented along the intersecting line as far as possible. After processing and connection, there are many different connection modes in addition to welding. The joint is beautiful because it coincides with the dividing line, and no segmentation defects can be seen.
4.綜合連接法
4. Comprehensive connection method
主要運(yùn)用在變截面的鈑金工件的加工,特別是一些曲面的鈑金加工。一般變截面的鈑金加工,需要將曲面分割成不同特征的曲面零件,再分別對(duì)不同特征的曲面零件進(jìn)行分類加工,如需要開(kāi)具沖壓模具加工的單元,制作簡(jiǎn)易的加工工裝加工的單元,簡(jiǎn)單折彎的單元、曲線下料貧寒加工的單元等,再將這些單元拼接成為整體。
It is mainly used in the machining of variable cross-section sheet metal workpiece, especially some curved sheet metal machining. For general variable cross-section sheet metal processing, it is preferred to divide the surface into surface parts with different characteristics, and then classify and process the surface parts with different characteristics. For example, it is necessary to issue stamping die processing units, make simple processing tooling processing units, simple bending units, curve blanking poor processing units, etc., and then splice these units into a whole.
