The first row of suction nozzles 500 and the second row of suction nozzles 800 are respectively provided on both sides. The bottom of the first row of suction nozzles 500 is connected to the second mounting bracket 400 through a connecting block. A first piston assembly 200 is provided between the top of the bending mechanism 300 and the inner top of the first mounting bracket 100. A rectangular slot 410 is opened on one side of the top of the second mounting bracket 400. A collection trough 900 is provided directly below the rectangular slot 410. The collection trough 900 is used to collect impurities falling from the rectangular slot 410 for easy handling by staff.

[0042] The bending mechanism 300 is composed of a lifting plate 310 and a T-shaped bending die 320. The outer walls on both sides of the top of the T-shaped bending die 320 are provided with inclined portions 322.

Because the outer wall of the top of the T-shaped bending die 320 and the groove wall of the T-shaped mounting groove 312 are in clearance fit, it is convenient to install the T-shaped bending die 320 into the T-shaped mounting groove 312 or to remove the T-shaped bending die 320 from the T-shaped mounting groove 312.

When the limiting post 3111 moves into the second limiting hole 321, it can limit the T-shaped bending pressure knife 320 in the X-axis direction.

[0045] A spring 315 is fitted on the outer side of the outer wall of the connecting column 3112, and the spring 315 is located between the connecting frame 314 and the limiting plate 311.

An L-shaped connecting plate 318 is installed on one side of the upper surface of the lifting plate 310.

[0046] A second air inlet / outlet pipe 510 is provided on one side of the outer wall of the first row / air inlet nozzle 500 and the second row / air inlet nozzle 800. A plate filter screen 520 is provided on the other side of the outer wall of the first row / air inlet nozzle 500 and the second row / air inlet nozzle 800. The plate filter screen 520 is provided to prevent impurities from entering the interior of the first row / air inlet nozzle 500 or the second row / air inlet nozzle 800.

[0047] The first piston assembly 200 and the second piston assembly 700 are both composed of a first inlet / outlet pipe 210, a piston cylinder 220, a piston plate 230, a rubber piston 240 and a piston rod 250. The piston cylinder 220 is provided with a rubber piston 240 inside, and the rubber piston 240 is installed on one side surface of the piston plate 230. The piston rod 250 is installed on the other side surface of the piston plate 230. The first inlet / outlet pipe 210 is provided on one side of the circumferential outer wall of the piston cylinder 220.

[0048] The first inlet / outlet pipe 210 on the first piston assembly 200 is connected to the delivery pipe through a pipe joint, and the other end of the delivery pipe is connected to the second inlet / outlet pipe 510 on the first row / suction nozzle 500 through a pipe joint. The first inlet / outlet pipe 210 on the second piston assembly 700 is connected to the second inlet / outlet pipe 510 on the second row / suction nozzle 800 through a pipe joint.

[0049] The piston cylinder 220 of the first piston assembly 200 is mounted on the inner top of the first mounting bracket 100, the piston rod 250 of the first piston assembly 200 is mounted on the upper surface of the lifting plate 310, the piston cylinder 220 of the second piston assembly 700 is mounted on the top of the second mounting bracket 400, and the piston rod 250 of the second piston assembly 700 is mounted on the lower surface of the L-shaped connecting plate 318.

[0050] The hydraulic telescopic rod 110 is installed at the top of the first mounting bracket 100, and the bottom end of the hydraulic telescopic rod 110 passes through the top of the first mounting bracket 100.

[0051] Working principle: When in use, connect to an external power source. When there are many impurities at the bottom of the bending forming tank 600 and cleaning is required, the operator activates the hydraulic telescopic rod 110, causing the bending mechanism 300 to move upwards in a linear motion along the Y-axis. The bending mechanism 300 moves upwards to its maximum stroke. As the bending mechanism 300 moves upwards, the first piston assembly 200 is compressed with air. This compressed air state causes the first exhaust / suction nozzle 500 to exhaust air. The bending mechanism 300 then moves upwards... When the second piston assembly 700 is in the suction state, the second exhaust / suction nozzle 800 is also in the suction state. When the first exhaust / suction nozzle 500 and the second exhaust / suction nozzle 800 are in the suction state, the impurities on the inner bottom of the bending forming groove 600 are effectively blown out from one end of the bending forming groove 600 and fall into the collection groove 900 through the rectangular slot 410 for collection. Thus, this invention can automatically remove impurities that fall into the bending forming groove 600 during the steel plate bending process. Impurities are eliminated, eliminating the need for manual cleaning of the impurities within the bending forming tank 600, thus reducing workload and improving efficiency. When workers need to replace different models of T-shaped bending knives 320, to disassemble the T-shaped bending knives 320, workers pull the lifting plate 313 to move the limiting post 3111 out of the second limiting hole 321, and then pull the T-shaped bending knives 320 to remove them from the lifting plate 310. When installing the T-shaped bending knives 320, workers... The top of the pressure knife 320 is installed in the T-shaped mounting groove 312. The inclined part 322 on the T-shaped bending pressure knife 320 will contact the limiting post 3111 first and squeeze the limiting post 3111 during the movement. As the T-shaped bending pressure knife 320 continues to push, the limiting post 3111 will move from the inclined part 322 to the top of the T-shaped bending pressure knife 320 and automatically spring back into the second limiting hole 321 under the action of the spring 315. At this time, the installation of the T-shaped bending pressure knife 320 is completed. Thus, this utility model facilitates the disassembly and assembly of the T-shaped bending pressure knife 320 by the staff.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
