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.
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.
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.
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.
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.
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.
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.
