Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel flange processing, in particular to a stainless steel flange continuous stamping device and method. Background Art

[0002] Flange stamping is a common metal processing process, which is mainly used to manufacture various stainless steel flanges, such as pipe flanges and mechanical flanges. The process involves placing a metal sheet on a punch press and using the pressure of the punch press and the action of the die to stamp the metal sheet into the desired shape and size. In order to manufacture flanges of different processes, different stamping dies need to be replaced. The Chinese patent authorization publication number CN106694698B is a stamping die for flange blanks and its stamping forming device, which belongs to the field of stamping forming equipment, including a frame, a hydraulic mechanism, and a stamping die; the hydraulic mechanism is connected to the frame and its hydraulic column is extended and retracted downward, a bracket is provided under the hydraulic mechanism and the bracket is connected to the frame, and the stamping die includes a stamping head and a stamping seat, which are respectively fixed relative to the hydraulic column and the bracket; the stamping head and the stamping seat can cooperate to cut the hole or edge of the flange. The die stamping method has a high pass rate and simplifies the production of flange blanks; it solves the problem that the traditional flange blank production uses gas flame cutting, and each product needs to be marked with a center point, which has high technical requirements for workers; it overcomes the defects of traditional flame gas cutting that produces more iron oxide and reduces the amount of steel plate residue; it solves the problem that the steel plate is easily deformed when heated and the blank size cannot be properly controlled in the flame cutting process; it reduces the labor intensity of flange blank production and solves the problem that gas cutting cannot solve it when the inner hole is small; A stainless steel flange continuous stamping device with a Chinese patent authorization publication number of CN116174576B includes a base, an upper surface of the base is fixedly connected to a workbench, a turntable is rotatably connected to the upper surface of the workbench, a circular mounting plate is connected to the upper surface of the turntable, and a flange blank is provided on the top of the circular mounting plate. The first rotating shaft and the toothless gear are driven to rotate by a driving motor. Under the action of the toothless gear, the full gear and the second rotating shaft of its outer wall rotate at a fixed angle at the same time, so that the turntable on its top and the flange blank rotate at a fixed angle. As the toothless gear continuously drives the full gear to rotate, the flange blank can automatically adjust the stamping position. Since the number of tooth blocks of the toothless gear is fixed, the toothless gear meshes with the full gear each time and drives it to rotate at the same angle, ensuring that the spacing between each punched connection hole is the same, thereby improving the quality of the finished flange. Most existing technical solutions still have the following defects: it is difficult to complete the stamping operation of flanges of different sizes using a single upper mold, and the degree of automation is low, and manual labor is still required to frequently pick up and place the flanges. Therefore, the present invention provides a stainless steel flange continuous stamping device to solve the above-mentioned problems. Summary of the Invention

The stainless steel flange continuous stamping device according to claim 1, wherein the stamping method comprises the following steps: Step 1: placing the flanges to be processed at equal intervals on a conveyor belt (2) for transmission, and the conveyor belt (2) transmits the flanges to the bottom of the connecting plate (12); Step 2: Start the motor installed on the upper end of the rotating wheel (6), and the rotating wheel (6) drives the adjusting mechanism (11) to move up and down, thereby driving the stamping die (16) to stamp the flange; Step 3: When the connecting plate (12) moves downward, the contact mechanism (17) contacts the telescopic plate (304), causing the connecting plate (12) to rotate. When the connecting plate (12) moves upward, the contact mechanism (17) contacts the conical plate (21), causing the connecting plate (12) to rotate again at a certain angle for subsequent stamping. Step 4: By means of the threaded connection between the second adjusting rod (14) and the fixing block (15) and the worm gear structure, the spacing between the fixing blocks (15) is adjusted, thereby adjusting the spacing between the stamping dies (16) to adapt to the flange stamping process of different sizes; Step 5: By detachably connecting the mounting ring (1704) to the adapter plate (12) and slidingly connecting the extension plate (1703) to the main plate (1701), the overall extension length and inclination of the contact mechanism (17) can be adjusted to accommodate different numbers of hole processing; Step 6: By means of the detachable connection between the first fixing plate (301) and the second fixing plate (302) and the connecting plate (303) and the mounting column (23) and the retractability of the retractable plate (304), the spacing between the first fixing plate (301) and the second fixing plate (302) is adjusted to adapt to the angle and length changes of the contact mechanism (17) and ensure that the stamping die (16) is driven to rotate.
