The punching pressing column 60 can be used to punch the punching movable column 79 at the corresponding position, so that the punching movable column 79 punches the corresponding position of the flange that has been punched, and after the punching is completed, the pressing pad 59 is supported by the rebound support spring 61, so that the punching pressing column 60 is away from the punching movable column 79, and the punching movable column 79 is supported by the punching rebound compression spring 82 to return to the punching guide hole 81, waiting for the next punching; the pressing pad 59 and the support pad 58 of the same thickness are used, so that the stroke of the press is not changed when switching between the two states.

[0044] Furthermore, the control box 1 is fixed on the top of the conveying channel 2, and a control button 16 is arranged on the top of the control box 1, and a controller, a rotation drive circuit and a conveying drive circuit are arranged in the control box 1; the controller is electrically connected to the control button 16, the first photoelectric switch 48, the second photoelectric switch 87, the rotation drive circuit and the conveying drive circuit respectively; the controller adopts the existing single-chip microcomputer control module; the first photoelectric switch 48 and the second photoelectric switch 87 both adopt the existing photoelectric switches for target position detection; the control button 16 includes a start button and a stop button for realizing the start and stop control of the system; the rotation drive circuit and the conveying drive circuit both adopt the existing stepping motor drive circuit for driving and controlling the rotation drive motor 69 and the conveying drive motor 3 respectively.

[0045] When the flow-type stamping forming system for flanges disclosed in the present invention is working, first, a worker pulls the end of the strip steel plate 100 through the conveying channel 2, and the lower side of the strip steel plate 100 on the feeding side is supported on each supporting roller 15, the strip steel plate 100 in the conveying channel 2 is clamped between the pressing roller 21 and the anti-slip support sleeve 23, the edge of the strip steel plate 100 on the unloading side is clamped and limited between the lower support ring 34 and the upper support ring 37, and the strip steel plate 100 is located between the upper stamping die 63 and the lower stamping die 73;

[0046] After the system is started, the support pad 58 is first located above the pressing seat 53 and is punched by the press. The support pad 58 is pressed down together with the pressing seat 53, and a flange is punched out from the strip steel plate 100 by the upper punching die 63 and the lower punching die 73. The second photoelectric switch 87 detects a downward rebound process, and then the controller drives and controls the rotary drive motor 69 to move the pressing pad 59 to the top of the pressing seat 53 and is punched by the press. The pressing pad 59 is pressed down together with the pressing seat 53, and at the same time, the punching pressing column 60 punches the punching active column 79, and the lower end of the punching active column 79 punches a hole at the corresponding position of the flange. After the second photoelectric switch 87 detects a downward pressing and rebounding process again, the controller waits for a set time. At this time, the worker takes out the flange that has been pressed and punched from the lower stamping die 73. When the waiting time is reached, the controller drives and controls the conveying drive motor 3 to move the strip steel plate 100 laterally. When the first photoelectric switch 48 detects that the remaining material of the strip steel plate 100 moves laterally by an interval, the controller stops driving the conveying drive motor 3. At this time, the next flange stamping position is already located between the upper stamping die 63 and the lower stamping die 73; the above process is repeated to complete the stamping and punching construction of each flange.

[0047] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and details may be made without departing from the spirit and scope of the present invention as defined in the appended claims.
