6. The fixed length punching device for processing a photovoltaic bracket according to claim 1, wherein: both ends of the upper die (24) penetrate through and are connected to the outer wall of the guide post at the upper end of the support frame (2) in a sliding manner.
7. The fixed length punching device for processing a photovoltaic bracket according to claim 1, wherein: the upper wall of the guide groove of the lower die (8) and the lower wall of the seat end of the stamping head (25) are respectively provided with stamping lines.
8. A fixed length punching device for processing a photovoltaic bracket according to any one of claims 1 to 7, characterized in that: the process flow of the fixed-length punching device for processing the photovoltaic bracket comprises the following steps of:
step one, according to the length of a required photovoltaic bracket, a stepping motor (20) is controlled to drive a screw rod (21) to rotate, and then an adjusting plate (7) is driven to move, the adjusting plate (7) drives a baffle plate (23) to move to a preset position, when a C-shaped square tube for manufacturing the photovoltaic bracket is inserted into a guide part (10) and is continuously sleeved into a guide groove of a lower die (8), the C-shaped square tube is blocked when the C-shaped square tube contacts the baffle plate (23), and then the length adjustment of the photovoltaic bracket is realized;
step two, the hydraulic cylinder (4) drives the stamping frame (5) to descend, so that the blanking guillotine (9) descends to perform blanking on the C-shaped square tube, and isometric cutting of the photovoltaic bracket is realized under the cooperation of the baffle plate (23);
step three, after the C-shaped square tube is blanked and cut off, the hydraulic cylinder (4) drives the stamping frame (5) to ascend, so that the fixed plate (16) fixedly connected with the stamping frame (5) ascends, and further the pawl (19) is driven to ascend, under the elastic action of the flat spring (17), the pawl (19) is always in contact with the ratchet wheel (15), and further the ratchet wheel (15) is driven to rotate, the rotating shaft (14) is driven to rotate, the sprocket (12) is driven to rotate, the chain (13) is driven to move, and finally the lower die (8) moves to the next punching station along with the chain (13);
and step four, when the hydraulic cylinder (4) drives the stamping frame (5) to descend, the stamping head (25) is also driven to punch the C-shaped square tube cut off by blanking, and the ratchet wheel (15) cannot be caused to rotate due to the fact that the other pawl (19) is limited, the ratchet wheel (15) can only rotate along one direction, the lower die (8) sequentially and circularly moves along one direction, and then production line type production is achieved.
