    统一在降低消费成本,节约社会资源,减少电子废弃物方面发挥了有目共睹的作用。但该标准在具体实施过程中也出现了一些问题,如有些适配器外壳不支持U充电,强行执行这一标准会导致电压调整器损坏和充电时接通率下降等问题。

    Unification has played an obvious role in reducing consumption costs, saving social resources and reducing electronic waste. However, there are some problems in the implementation of this standard. For example, some adapter shells do not support U charging. Implementing this standard will lead to the damage of voltage regulators and the decrease of connection rate during charging.

    杭州精密钣金加工厂家,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。

    Hangzhou Precision Sheet Metal Processing Factory, punch: is the use of mold forming process, the general punch processing has punching, cutting, blanking, punching convex hull (bump), punching tearing, punching, forming and other processing methods, its processing needs the corresponding die to complete the operation, such as punching blanking die, convex hull die, tearing die, drawing. Hole die, forming die and so on. The operation mainly pays attention to position and direction.

    钣金工艺一般来说基本设备包括剪板机(ShearMachine)、数控冲床(CNCPunchingMachine)/激光、等离子、水射流切割机(CuttingMachine)、折弯机(BendingMachine)以及辅助设备如:开卷机、校平机、去机、点焊机等。

    Generally speaking, the basic equipment of sheet metal process includes Shear Machine, CNC punching Machine/laser, plasma, water jet cutting machine, Bending Machine and auxiliary equipment such as uncoiler, leveler, stripper and spot welding machine.

    金属板材加工就叫钣金加工。具体譬如利用板材制作烟囱、铁桶、油箱油壶、通风管道、弯头大小头、天圆地方、漏斗形等,主要工序是剪切、折弯扣边、弯曲成型、焊接、铆接等,需要一定几何知识。

    Metal sheet metal processing is called sheet metal processing. For example, making chimneys, barrels, oil tanks, ventilation pipes, elbows, places around the sky, funnel shapes, etc. with sheet metal, the main working procedures are shearing, bending and buckling edges, bending forming, welding, riveting and so on, which require certain geometric knowledge.

    杭州精密钣金加工厂家,(1)钣金考虑到不锈钢板材与普通钢板性能指标有所不同。如电焊焊接性能,普通钢板焊接方式采取气保焊、电弧焊接或氩弧焊等可以,相对较为广泛。而不锈钢板材则有所不同,一般来说采取特种焊接氩弧焊,电焊焊接空隙不可以过大,不然形变大,外型不美观。因此一般传统化钣金设计不可符合要求,不锈钢板材电焊焊接要求相对化。

    Hangzhou Precision Sheet Metal Processing Factory, (1) Sheet Metal takes into account that the performance index of stainless steel sheet is different from that of common steel sheet. For example, the welding performance of electric welding, gas shielded welding, arc welding or argon arc welding can be used in common steel plate welding, which is relatively widespread. The stainless steel plate is different. Generally speaking, special welding argon arc welding is adopted. The welding gap should not be too large, otherwise the deformation will be large and the appearance will not be beautiful. Therefore, the traditional design of sheet metal can not meet the requirements, and the welding requirements of stainless steel plate are relative.

    工件在折弯,压铆等工序完成后要进行表面处理,不同板材表面的处理方式不同,冷板加工后一般进行表面电镀,电镀完后不进行喷涂处理,采用的是进行磷化处理,磷化处理后要进行喷涂处理。电镀板类表面清洗,脱脂,然后进行喷涂。不锈钢板是在折弯前进行拉丝处理,不用喷涂,铝板一般采用氧化处理,根据喷涂不同的颜色选择不同的氧化底色,常用的有黑色和本色氧化。表面前处理这样做可以使清洁表面,显著提高涂膜附着力,能成倍提高涂膜的耐蚀力。清洗的流程先清洗工件,先将工件挂在流水,经过清洗溶液中(合金去油粉),然后进入清水中,其次经过喷淋区,再经过烘干区,后将工件从流水取下。

    Workpiece surface treatment after bending, riveting and other processes are completed. Different plate surface treatment methods are different. After cold plate processing, surface electroplating is generally carried out. After electroplating, no spraying treatment is carried out. Phosphating treatment is adopted and spraying treatment is carried out after phosphating treatment. The surface of plating plate is cleaned, degreased and then sprayed. Stainless steel plate is drawn before bending without spraying. Aluminum plate is usually treated by oxidation. Different oxidation background colors are selected according to different spraying colors. Black and natural colors are commonly used for oxidation. Surface pretreatment can clean the surface, significantly improve the adhesion of the film, and can double the corrosion resistance of the film. The cleaning process first cleans the workpiece, first hangs the workpiece in the running water, first passes through the cleaning solution (alloy degreasing powder), then enters the clean water, secondly passes through the spray area, then passes through the drying area, then takes the workpiece off the running water.


    其次,钣金结构设计需要考虑材质加工要求及成本控制。设计图纸中应明确对制作材料的要求,要做好对材料选择的要求,保证选择正规厂家生产的高质量材料,确保材料在实际制作中能够符合相关标准的要求,保证设计成品能够达到设计的性能要求;在设计中要严格控制产品制作中材料的冲折率,在保证产品性能的前提下尽量降低产品实际制作中工序的繁琐性,增强设计图纸的可操作性;要确保选用的材料具备较好的强度,易于弯曲。

    Secondly, the design of sheet metal structure needs to consider material processing requirements and cost control. In the design drawings, it is necessary to specify the requirements for the materials to be manufactured, to select the high-quality materials produced by the regular manufacturers, to ensure that the materials can meet the requirements of the relevant standards in the actual production, to ensure that the finished products can meet the performance requirements of the design, and to strictly control the production of the products in the design. Under the premise of guaranteeing the product performance, the breaking rate of medium materials can minimize the tedious process in the actual production of products, enhance the operability of design drawings, and ensure that the selected materials have better strength and are easy to bend.
