1. The method and characteristics of automatic processing of sheet metal machinery
1.1 Analysis of automatic processing methods of sheet metal machinery
Metal mechanical applications of sheet metal can be divided into five processing methods:
First, use a single pressure. Metal parts are formed by arc, pore, mesh, etc., using single pressure to separate the metal structure in a short time to form the final metal product.
Second, start from the order that the sheet metal processing method can be divided into one-way and multiple directions. Among these methods, it is generally suitable for large-scale sheet metal processing or the formation of large metal holes, while the unilateral method is suitable for the accumulation of multiple metal parts. By placing different mechanical angles and functions, different sequencing processing results can be achieved.
Third, follow-up processing. This missing treatment is called the language process, which is mainly to grind the metal part and process it later. Mills usually feature small circular dies with small supports for accurate positioning during operation.
Fourth, single or multiple continuous sheet metal processing. According to the numerical control machine, under the premise of the knowledge base for reference and use, which improves the quality of sheet metal forming and the overall improvement of processing design effects.
3.3 Application of laser cutting technology
In the automatic processing of sheet metal, the basic working principle of the laser cutting machine is to concentrate the laser beam on the surface of the steel plate. After the laser is fired, the focused light can be converted into heat, creating multiple heat beams. In a short period of time, the heat generated quickly rises to the melting point of the plate and reaches the boiling point, resulting in a higher temperature in a short period of time. When the sheet is melted and evaporated, a higher internal precision occurs at the point of laser radiation. The laser-cutting machine adjusts the trajectory of the upper note in advance according to the power of the device itself, so as to facilitate the movement of the laser beam. During the movement of the laser beam, continuous melting and evaporation reactions will occur when the plate is in contact with the laser beam. The reaction continued, and the board showed laser cracks on the surface of the line panel from the active site. Compared with traditional sheet metal cutting technology, laser cutting technology has obvious advantages. This is mainly reflected in the following aspects: First, the speed is faster, the laser beam starts from the surface of the plate, melts and evaporates, and completes the cutting process. During the laser drilling process, the metal sheet rapidly reaches its melting and boiling points within minutes, completing the electro-optical cutting process between the silicas. Second, the cutting quality is high, due to the fast cutting time and speed, the laser beam will not ignore the cutting quality. With the emergence of a large number of laser cutting products, the cutting seam is not only small but also the flatness and smoothness of the cutting model are also very good. There are no rough edges or dents when cutting, and the overall cutting quality is reliable. This doesn't have any noticeable negative impact on the sheet itself. If the traditional cutting method is used for cutting, the tool has a great influence on the working surface of the plate, which has a great influence on the properties of the material. Finally, laser cutting itself has high flexibility, mainly reflected in the area, which can adapt to different shapes of metal sheets. Demand for sheet metal is not high. Most materials can meet the requirements of laser cutting applications and meet the requirements of the modern CNC chemical industry.
