[0033] The bending die 3 has an elongated groove 26 inside. A straightening frame 4 is fixedly connected to the top of the bending die 3. Both the bending die 3 and the straightening frame 4 are made of stainless steel. Because they contain less iron and nickel, they will not be attracted by the magnetic force generated by the electromagnet 23. The elongated groove 26 allows the punch 9 to punch holes in the sheet metal better. The straightening frame 4 is used to prevent the sheet metal from shifting during placement, which would result in poor quality of the punched and bent sheet metal.

[0034] Several blocking blocks 53 are fixedly connected to the bottom of the bending die 3. Square holes 54 are opened inside the blocking blocks 53. Several grooves 52 are opened inside the lower die box 5. The interior of the grooves 52 is slidably connected to the blocking blocks 53. A sliding groove 35 is opened inside the lower die box 5 and on one side of the grooves 52. A spring 34 is fixedly connected to one side of the sliding groove 35. A sliding block 36 is fixedly connected to the other end of the spring 34. A plug-in block 33 is fixedly installed on one side of the sliding block 36. The sliding block 36 is located inside the sliding groove 35 and slidably connected to it. The plug-in block 33 is inserted into the square hole. Inside the lower mold box 54, a trapezoidal groove 51 is provided. A pull rope 31 is installed inside the trapezoidal groove 51. Both ends of the pull rope 31 are inserted into the sliding groove 35 and fixedly connected to the sliding block 36. One end of the pull rope 31 extends to the outside of the lower mold box 5 and is fixedly connected to a pull ring 32. The operator can pull the pull rope 31 through the pull ring 32 to make the two pull ropes 31 drive the two sliding blocks 36 to slide. The sliding block 36 will squeeze the spring 34, causing the spring 34 to undergo elastic deformation, pulling the plug block 33 out of the blocking block 53, thereby allowing the lower mold 3 to be disassembled and bent.

[0035] In summary, when using this sheet metal bending and punching device for machining, the operator first starts the motor 45, which drives the crescent-shaped block 41 to rotate. The action of the actuating column 43 and the square slot 46 then drives the rotator 39 and the rotating block 6 to rotate. Before bending and punching the sheet metal, the operator inserts the upper bending die 19 into the fixed block 18, and then secures it by simultaneously screwing bolts 28 into both the upper bending die 19 and the fixed block 18. Next, the operator pulls the two pull ropes 31 using the pull ring 32. The tension on the pull ropes 31 causes the sliding block 36 to slide. The compression of the spring 34 by the sliding block 36 causes the spring 34 to deform elastically, pulling the insertion block 33 out of the groove 52. Then, the lower bending die 3 is inserted into the groove 52 through several blocking blocks 53. When fully inserted, the operator can release the pressure, and the elastic force of the spring 34 allows the insertion block 33 to insert into the square hole 54, thus... To achieve a fixed effect, the sheet metal part is placed inside the straightening frame 4 to reduce shaking during rotation. The device rotates 90° at a time. When rotating the first 90°, the sheet metal part will be bent. The bending die 19 moves up and down through the hydraulic cylinder 17, thus bending the sheet metal part. The bent sheet metal part will be punched after the second rotation. Four rotations constitute one work cycle. When the sheet metal part is directly below the punch 9, the operator rotates the lead screw 12 through the handle 11, causing the moving block 50 to move left and right to punch holes in different positions of the sheet metal part. After punching, the sheet metal part is rotated to directly below the electromagnet 23 by rotating the circular block 6. The electric telescopic rod 21 is remotely controlled to make the electromagnet 23 contact the sheet metal part. The sheet metal part is attracted by the magnetic force. Then, the rotating plate 22 is rotated by the motor 45. After rotation, the electromagnet 23 loses its magnetic force, and the sheet metal part falls into the collection box 2, thus achieving the purpose of convenient collection of the sheet metal part.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
