Description

Technical Field

[0001] The invention relates to the technical field of sheet metal machine tools, in particular to a drilling device used for sheet metal machine tools. Background Art

[0002] Sheet metal is a processing technology. Sheet metal is a comprehensive cold processing technology for metal thin plates (usually less than 6mm), including shearing, punching / cutting / compounding, folding, riveting, splicing, forming (such as car body), etc. Sheet metal has the characteristics of light weight, high strength, conductivity (can be used for electromagnetic shielding), low cost, and good performance in large-scale mass production. It has been widely used in electronics, communications, automotive industry, medical equipment and other fields. For example, in computer cases, mobile phones, and MP3s, sheet metal is an indispensable component. The main methods of sheet metal punching include laser cutting, punching and wire cutting. These methods have their own characteristics and are suitable for different production needs and material types. Punching operations are usually used in mass production because mold opening is required. If the production volume is not large, the punching operation may not be economical. Punching is suitable for various standard round hole processing, but it is not suitable for single-piece or small-batch production. 2. Wire cutting is a method of cutting by electric spark erosion of materials. It is suitable for processing with high precision requirements, but the speed is slow. It is suitable for processing holes of complex shapes. The advantage of wire cutting is high processing accuracy, but the disadvantage is that the equipment cost is high and the cutting nozzle needs to be replaced regularly. 2. When choosing a sheet metal punching method, factors such as material type, complexity of the hole and production batch need to be considered. Laser cutting is suitable for efficient and precise mass production; punching is suitable for mass production of standard holes; wire cutting is suitable for processing of complex shapes and high precision requirements. ‌ When the existing drilling device is in use, such as application number CN202121200942.6, which discloses a drilling device for a sheet metal machine tool, includes a drill bit and a base, a groove is opened inside the base, and a horizontal adjustment device is provided in the groove.
