[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / compounding, folding, welding, riveting, splicing, forming, etc. Its notable feature is that the thickness of the same part is consistent;

[0003] Products processed by sheet metal technology are called sheet metal parts. During the processing of sheet metal parts, it is sometimes necessary to press different types of indentations on the sheet metal parts, so an indentation device is needed to perform indentation treatment. Currently, most indentation devices use indentation plates to pressurize sheet metal parts to achieve indentation treatment.

[0004] However, when using an indentation plate to indent sheet metal, the indentation plate needs to be pressed into the sheet metal to achieve the indentation effect. Therefore, after the indentation is completed, the sheet metal is very likely to stick to the indentation plate, and the stuck sheet metal needs to be manually removed, which increases the workload and poses certain safety hazards.

[0027] Among them, when the indentation plate 7 is replaced: by providing a connecting component, the sliding member 10 connected to the indentation plate 7 is correspondingly engaged in the slideway 9 for simple fixation. At this time, the sliding member 10 is connected to the connecting seat 8, and then the sliding member 10 is fixed to the connecting seat 8 by the reinforcing bolts 11. The overall installation and disassembly are convenient, and the installation and disassembly work can be guided by the slideway 9 and the sliding member 10, and it is convenient to replace different indentation plates 7 for use.

[0028] like Figure 6 As shown, four pressure rods 12 are arranged in a rectangular shape on the mounting platform 5, and the pressure rods 12 are located on both sides of the indentation plate 7, a fixing block 13 is installed at the bottom of the pressure rod 12, a flexible pad 14 is installed on the lower surface of the fixing block 13, and a limiting block 15 is installed on the top of the pressure rod 12, and a pressure spring 16 is sleeved on the outside of the pressure rod 12, and the pressure spring 16 is located between the mounting platform 5 and the fixing block 13, and the sheet metal is pushed by the pressure spring 16 to avoid adhesion with the indentation plate 7;
