The precision sheet metal parts are the sheet metal parts, and the sheet metal processing is the parts which can be processed by means of stamping, zigzag and stretching. A general explanation is the parts with constant thickness during the process of processing, which correspond to the casting parts, forgings, mechanical parts and so on. Metal sheet processing is called precision sheet metal processing. For example, using plate to make chimneys, iron buckets, oil tank oil pot, ventilation pipe, big head of elbow, local area of Tianyuan, funnel shape and so on. The first procedure is cutting, bending and buckling, twists forming, welding, riveting and so on. It needs to master some geometric knowledge.
当重新审视新的精密钣金加工工艺：激光切割--折弯--焊接/铆焊时，由于激光切割的高柔性、高精度，三维设计技术的成熟与普及，用户可从新的设计、新的流程中获益，从而达到降低成本、缩短工期的要求。在多品种，小批量，定制化，高质量，短交货期的订单面前，它显现出明显的不适应。激光切割工艺作为“剪切--冲”的替代工艺出现，具有灵活、柔性高的特点。同时多数人也认为其成本高。故常应用在异形(或形状复杂的)工件和样品(单件或极小批量)制造上。但当小批量制造越来越普及时，激光切割的需求也日益上升。因此新的精密钣金工艺是从设计开始的：设计激光切割 折弯 焊接/铆焊。
What is the process of precision sheet metal processing
The conventional precision sheet metal processing technology is shearing, punching - bending - welding process or flame plasma cutting - bending - welding process.
When the new precision sheet metal processing technology is re examined: laser cutting - bending - Welding / riveting welding, because of the high flexibility and precision of laser cutting and the maturity and popularization of the 3D design technology, the users can benefit from the new design and new process, thus reducing the requirements of the cost and the shortening period. In the face of many varieties, small batch, customized, high quality, short delivery time orders, it shows obvious lack of adjustment. Laser cutting technology appears as an alternative technology of shear and impact. It has the characteristics of flexibility and flexibility. At the same time, most people also think its cost is high. It is often used in the manufacture of special-shaped (or complex) workpieces and samples (single or small batch). But when small batch manufacturing is becoming more and more popular, the demand for laser cutting is also increasing. Therefore, the new precision sheet metal process starts with design: designing laser cutting bending welding / riveting.
Precision sheet metal processing in the next five to fifteen years will have a positive impact on China's implementation of the third step strategic deployment. The rise of the precision sheet metal processing enterprises has saved the enterprises to buy the original data, transport and other miscellaneous orders, save a lot of manpower, material and energy, and save many internal resources such as investment building, equipment, recruitment, inventory, management data. In the metal processing industry, the precision sheet metal processing becomes an essential part. Beijing Kai Zhong communication equipment will introduce you to the latest and the most complete precision sheet metal processing technology. Let you familiarize yourself with the precision sheet metal processing technology, let you easily grasp the process of precision sheet metal processing, and welcome the reprint of the communications equipment. Article, but please indicate the origin of our article. The form of precision sheet metal processing and distribution broke the traditional logistics procurement and transportation practice, introduced the concept of processing and distribution, which widened the horizon and accelerated the integration of traditional mechanical production and skills.
The development of precision sheet metal processing technology
In precision sheet metal processing, the strength and rigidity of the material and the thickness should not be too thin. The material must be straight, otherwise it will affect the accuracy of the workpiece. When making the template, we must mark with sharp line needle and sharp sample, and do fine and line, then cut with scissors, the edge must be neat.
For the model already made, it should be kept well without bending or other deformation. Otherwise, it will affect the quality of the work piece. For standard or commonly used templates, they should be kept properly for use next time. The machining symbols should be marked on the template, and the engineering number, workpiece number, specification, quantity, hole diameter, etc. should be specified. The word and character symbols on the template should be written in enamel lacquer and should be correct.
When you have finished, you must check it by yourself, and then check it by the inspection department. The development of precision sheet metal processing technology is to focus the laser beam on the surface of the material by focusing the laser beam, and melt the material. At the same time, the material is blown away by the compressed gas coaxial with the laser beam, and the laser beam and the material are moved along a certain trajectory to form a certain shape. Laser cutting technology is widely used in the machining of metal and non-metallic materials such as machine tools, engineering machinery, electrical switches, elevator, grain machinery, textile machinery, locomotive manufacturing and so on. The laser cutting technology greatly reduces the processing time, reduces the processing cost and improves the quality of the workpiece.
