A first moving block 8 is installed on the screw rod 7. The upper and lower sides of the first moving block 8 are connected with first sliding blocks 11, and the first sliding blocks 11 are slidably arranged in the first sliding groove 10;

[0024] A moving column 9 is fixed on the outer side of the first moving block 8. A rectangular groove is provided on the moving column 9, and a second sliding groove 15 is provided on the inner wall of the rectangular groove. A first cylinder 12 is installed above the moving column 9. The output end of the first cylinder 12 is connected to a first telescopic rod 13. The bottom end of the first telescopic rod 13 is installed with a second moving block 14. The two sides of the second moving block 14 are connected with second sliding blocks 16, and the second sliding blocks 16 are slidably arranged in the second sliding groove 15.

[0025] During operation, when the stamping and forming of the backlight iron frame is completed, the motor 6 is started. The motor 6 drives the screw rod 7 to rotate. The rotation of the screw rod 7 drives the first moving block 8 to move. The movement of the first moving block 8 drives the moving column 9 to move left and right. When the moving column 9 reaches the position, the first cylinder 12 is started. The first cylinder 12 drives the first telescopic rod 13 to move. The movement of the first telescopic rod 13 drives the second moving block 14 to move. The movement of the second moving block 14 drives the rectangular plate 33 to move, facilitating the rapid movement of the machine for material taking and improving the work efficiency.

[0026] Furthermore, a lower die base 23 is provided above the workbench 1. Four groups of load-bearing sleeves 24 are installed above the lower die base 23. A moving plate 18 is slidably installed on the four groups of support columns 2. An upper die base 25 is installed below the moving plate 18. Four groups of load-bearing rods 26 are installed below the upper die base 25. The positions of the four groups of load-bearing rods 26 correspond to the positions of the four groups of load-bearing sleeves 24. Fixed blocks 22 are fixed on both sides of the upper die base 25.

[0027] During operation, when the iron sheet is sent to the lower die base 23 for stamping, the upper die base 25 moves downward to stamp and form the iron sheet, realizing the stamping and forming of the backlight iron frame and improving the work efficiency.

[0028] Further, a second fixing plate 17 is fixedly installed on the support column 2. The second fixing plate 17 is located below the moving plate 18. A clamping groove 27 is formed in the second fixing plate 17, and the clamping groove 27 is directly below the fixing block 22. A rectangular groove is formed in the second fixing plate 17, and a circular through hole is formed in the inner wall of the rectangular groove. The circular through hole penetrates the inner side surface of the clamping groove 27.

[0029] During work, when the upper die holder 25 moves downward to stamp and form the iron sheet, the fixing blocks 22 on both sides of the upper die holder 25 enter the clamping groove 27, which is convenient for limiting the upper die holder and improves work efficiency.

[0030] Further, a rectangular plate 33 is fixed to the outer side surface of the second moving block 14. Four suction cups 34 are arranged below the rectangular plate 33.

The vacuum generator 35 is connected to the lower die holder 23 through an air pipe. A collection box 3 is arranged above the workbench 1, and the collection box 3 is located below the rectangular plate 33.

[0031] During work, when the iron frame is stamped and formed, under the movement of the moving column 9, the rectangular plate 33 reaches above the lower die holder 23. The vacuum generator 35 is started. When the vacuum generator 35 works, the suction cups 34 generate suction force to complete the clamping of the iron frame. Under the work of the moving column 9 and the motor 6, the rectangular plate 33 moves above the collection box 3, and the suction cups 34 release to complete the collection of the iron frame, realizing automatic blanking and improving work efficiency.

[0032] Further, a third fixing plate 19 is fixed on the support column 2. The third fixing plate 19 is located above the moving plate 18. Two second cylinders 20 are installed below the third fixing plate 19. The output ends of the two second cylinders 20 are connected with second telescopic rods 21. The bottom end of the second telescopic rod 21 is fixedly connected with the moving plate 18.

[0033] During work, when the iron sheet is placed on the lower die holder 23, the second cylinder 20 is started. The second cylinder 20 drives the second telescopic rod 21 to move when working. The second telescopic rod 21 drives the moving plate 18 to move. The moving plate 18 drives the upper die holder 25 to move downward, thereby realizing the stamping and forming of the iron frame and improving work efficiency.

[0034] Further, a support plate 28 is fixed above the workbench 1. A second support frame 29 is installed on the support plate 28. A third cylinder 30 is installed in the second support frame 29. The output end of the third cylinder 30 is connected with a third telescopic rod 31. The top end of the third telescopic rod 31 is connected with a limiting block 32. The limiting block 32 is located in the circular through hole.

[0035] During operation, when the upper die base 25 stamping-forms the iron frame, the fixing block 22 enters the card slot 27. To avoid machine injury, when there is no iron sheet on the lower die base 23, the third cylinder 30 operates to drive the third telescopic rod 31 to move. The movement of the third telescopic rod 31 drives the limiting block 32 to move. The movement of the limiting block 32 presses against the fixing block 22 through the circular through-hole, causing the upper die base 25 to stop moving, thus enhancing the operation safety of the machine.

[0036] Working principle: After the iron sheet is placed on the lower die base 23, the second cylinder 20 is started. The second cylinder 20 operates to drive the second telescopic rod 21 to move. The movement of the second telescopic rod 21 drives the moving plate 18 to move. The movement of the moving plate 18 drives the upper die base 25 to move downward, thereby realizing the stamping and forming of the iron frame. After the backlight iron frame is stamping-formed, the motor 6 is started. The motor 6 operates to drive the screw rod 7 to rotate. The rotation of the screw rod 7 drives the first moving block 8 to move. The movement of the first moving block 8 drives the moving column 9 to move left and right. When the moving column 9 reaches the position, the first cylinder 12 is started. The first cylinder 12 operates to drive the first telescopic rod 13 to move. The movement of the first telescopic rod 13 drives the second moving block 14 to move. The movement of the second moving block 14 drives the rectangular plate 33 to move. Under the movement of the moving column 9, the rectangular plate 33 reaches above the lower die base 23. The vacuum generator 35 is started. When the vacuum generator 35 operates, the suction cup 34 generates suction to complete the sucking and tightening of the iron frame. Under the operation of the moving column 9 and the motor 6, the rectangular plate 33 moves above the collection box 3, and the suction cup 34 releases to complete the collection of the iron frame. When the upper die base 25 stamping-forms the iron frame, the fixing block 22 enters the card slot 27. To avoid machine injury, when there is no iron sheet on the lower die base 23, the third cylinder 30 operates to drive the third telescopic rod 31 to move. The movement of the third telescopic rod 31 drives the limiting block 32 to move. The movement of the limiting block 32 presses against the fixing block 22 through the circular through-hole, causing the upper die base 25 to stop moving, thus enhancing the operation safety of the machine.
