The cooperation of the positioning component and the bending block plays a role in measuring and positioning the position of the required bending segment of the iron sheet, which facilitates the equipment to accurately position the iron sheet at different positions, and is beneficial to improving the processing quality of the equipment. When the iron sheet positioning is completed, the iron sheet is fixed by the fixing component, and then the connecting block and the bending block are driven to descend synchronously by the second cylinder. The cooperation of the bending block and the bending groove can play the role of processing and bending the iron sheet. When the iron sheet processing is completed, the processed product can be ejected out of the bending groove by the ejection component, which is convenient for the staff to take the material later, and then the above operation can be repeated.

[0009] Furthermore, the correction assembly includes a first mounting seat fixedly installed on both sides of the base, the cross-sections of the two first mounting seats are both "L"-shaped, the inner sides of the vertical sections of the two first mounting seats are fixedly installed with a first cylinder, and the ends of the piston shafts of the two first cylinders are fixedly installed with a correction plate.

[0010] By adopting the above technical solution, when the iron sheet is conveyed by the first conveyor belt, the first cylinder then drives the correction plate on the same side to move.

The iron sheet is conveyed by the first conveyor belt so that the end of the iron sheet contacts the side opposite to the positioning plate, which can locate the position of the iron sheet, thereby facilitating the equipment to process different positions of the iron sheet without manual adjustment by personnel, which is conducive to maintaining the processing efficiency of the equipment.

[0015] Furthermore, the fixing assembly includes two groups of symmetrically distributed first telescopic rods arranged on the inner wall of the top end of the support frame, the connecting block is located between the two groups of first telescopic rods, there are two first telescopic rods on the same side and they are symmetrically distributed on the inner wall of the fixed section of the support frame, two symmetrically distributed mounting plates are provided in the support frame, the first telescopic rods on the same side are fixedly connected to the top end of the mounting plate on the same side, a fixing plate is provided under the two mounting plates, two symmetrically distributed pillars are fixedly installed on the bottom ends of the two mounting plates, movable grooves are provided at the bottom ends of the pillars, support rods are slidably installed in the movable grooves, springs are fixedly connected between the top end of the support rods and the inner wall of the top end of the movable grooves on the same side, the bottom ends of the two support rods on the same side are fixedly connected to the top end of the fixed plate on the same side, and a plurality of ball bearings distributed in a linear array are rotatably installed on the bottom ends of the two fixed plates.

[0016] By adopting the above technical solution, when the iron sheet is positioned, the first telescopic rod drives the mounting plate, pillar, support rod and fixed plate on the same side to descend synchronously, so that the fixed plate contacts the top of the iron sheet, which can press and fix the iron sheet, which is beneficial to maintaining the stability of the iron sheet during bending. When the fixed plate contacts the iron sheet, the fixed plate pushes the support rod to slide in the movable groove on the same side under the driving force of the first telescopic rod on the same side, and the support rod pushes the spring on the same side to contract, and the spring gives the support rod on the same side a rebound force to achieve a buffering effect. A ball bearing is provided at the bottom of the fixed plate for rotation, which can press and fix the iron sheet and facilitate slight movement of the iron sheet when bending.

[0017] Furthermore, two symmetrically distributed limiting blocks are fixedly mounted on the side walls of the top ends of the support rods, and the inner wall of the movable groove is provided with limiting grooves that match the limiting blocks on the same side.

When the fixed plate 8 contacts the iron sheet, the fixed plate 8 pushes the support rod 9 to slide in the movable groove 25 on the same side under the driving force of the first telescopic rod 12 on the same side, and the support rod 9 pushes the spring 26 on the same side to contract.

When the iron sheet positioning is completed, the iron sheet is fixed by the fixing component, and then the connecting block 14 and the bending block 13 are driven to descend synchronously by the second cylinder 16. The cooperation of the bending block 13 and the bending groove 27 can play the role of processing and bending the iron sheet. When the iron sheet processing is completed, the processed product can be ejected out of the bending groove 27 by the ejection component, which is convenient for the staff to take the material later, and then the above operation can be repeated.
