[0002] Stainless steel is steel with stainless and corrosion resistance as its main characteristics, and the chromium content is at least 10.5%, and the carbon content is no more than 1.2%. Stainless steel is the abbreviation of stainless acid-resistant steel. Steel that is resistant to weak corrosive media such as air, steam, and water or has stainless properties is called stainless steel; and steel that is resistant to chemical corrosive media (acid, alkali, salt, etc.) is called acid-resistant steel.

[0003] Stainless steel product processing refers to the process of cutting, folding, bending, welding and other mechanical processing of stainless steel to obtain stainless steel products required for industrial production based on the properties of stainless steel. Drilling is a processing technology in the process of stainless steel product processing.

7. A drilling method for processing stainless steel products, based on a drilling device for processing stainless steel products according to any one of claims 1 to 6, characterized in that: The following specific methods are included: Step 1: Replace the model of the drill bit (12) to be used, disassemble the first pressing plate (3) and the second pressing plate (11) through the clamp (22), replace the first pressing plate (3) and the second pressing plate (11) with a channel diameter that is 1.1-1.2 times the outer diameter of the drill bit (12) according to the model of the drill bit (12), unscrew the hexagon socket bolt (9) to disassemble the adjustment plate (4), the spring (27) pushes the ejection rod (29) to rise to eject the adjustment plate (4) out of the placement groove (18), and replace the adjustment plate (4) with a circular hole diameter that is 1.1-1.2 times the outer diameter of the drill bit (12), so as to facilitate the fixation of stainless steel products with different drilling requirements and improve the practicality of the equipment; Step 2: Place the stainless steel product to be drilled on the workbench (10), and make the bottom of the stainless steel product contact the upper end of the workbench (10). The lifting cylinder (13) drives the drill bit (12) and the first pressing plate (3) and the second pressing plate (11) to descend. The first pressing plate (3) and the second pressing plate (11) first contact the stainless steel product and apply pressure to the stainless steel product. The pressure on the stainless steel product is detected by the pressure sensor (5). During the process of the first pressing plate (3) and the second pressing plate (11) applying pressure to the stainless steel product, the electric The push rod (2) contracts, driving the first pressing plate (3) and the second pressing plate (11) to rise, so that the pressure applied by the first pressing plate (3) and the second pressing plate (11) to the stainless steel product is kept within a safe range, and as the lifting cylinder (13) drives the cover (14) to continue to descend, the drilling hole is drilled into the stainless steel product through the channel between the first pressing plate (3) and the second pressing plate (11), and passes through the circular hole between the adjustment plate (4) and the through hole (19), thereby greatly reducing the deformation around the drilling hole of the stainless steel product and improving the processing quality of the stainless steel product; Step 3: The lifting cylinder (13) drives the cover (14) to rise and reset, the drill bit (12) leaves the drill hole and moves toward the top of the stainless steel product, the pressure sensor (5) detects the pressure change on the stainless steel product, and the piston rod of the electric cylinder extends downward to keep the pressure on the stainless steel product within the set range until the first pressure plate (3) and the second pressure plate (11) leave the stainless steel product, and the stainless steel product is removed from the workbench (10) to prevent the stainless steel product from moving when the drill bit (12) is pulled out of the stainless steel product, causing friction between the drill hole surface and the inner wall of the drill hole of the stainless steel product, thereby affecting the drilling quality; Step 4: Take out the cleaning brush (8) from the placement box (7), clean the metal debris on the upper surface of the workbench (10), and put the cleaning brush (8) back into the placement box (7) after cleaning to prevent the debris from remaining on the surface of the workbench (10) and interfering with the detection of the pressure sensor (5).
