Description

Technical Field

[0001] This utility model relates to the field of bending machines, specifically to a bending machine loading and unloading device. Background Technology

[0002] A bending machine is a machine that can bend thin plates. When bending metal plates, a separate feeding mechanism is usually used to feed the metal plate into the bending machine. Then, a tool is used to drop the metal plate from the feeding mechanism into the bending area. After bending is completed, the unloading equipment can remove it. In the current technology, the feeding mechanism is generally standardized, and different feeding equipment corresponds to different bending machine models. However, some bending machines can bend plates of different specifications according to requirements, which requires the feeding equipment to be diverse. However, the current technology can only achieve stable feeding by changing different models of feeding equipment, and it needs to be changed again during the unloading process, which is very cumbersome.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0024] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0025] Please see Figure 1-2 According to an embodiment of the present invention, a bending machine loading and unloading device includes a base plate 1. An adjustment mechanism 2 is installed on the top of the base plate 1, and a feeding mechanism 3 is installed on the top of the adjustment mechanism 2. The feeding mechanism 3 has two sets, and the distance between the two sets of feeding mechanisms 3 can be changed by the adjustment mechanism 2, thereby adjusting according to the size of the metal sheet to be fed under actual conditions, improving adaptability. The adjustment mechanism 2 includes a first slide rail 4 fixedly arranged symmetrically and collinearly along the center of the base plate 1. A first slide block 5 is slidably installed on the first slide rail 4, and a lifting cylinder 6 is fixedly installed on the first slide block 5. The feeding mechanism 3 is fixedly installed at the output shaft end of the lifting cylinder 6. The height of the feeding mechanism 3 can be changed by the lifting cylinder 6, thereby enabling the metal sheet to be better fed into the worktable of the bending machine. The first slide rail 4 and the first slide block 5 can change the position of the lifting cylinder 6, thereby realizing the position adjustment of the two sets of feeding mechanisms 3.

[0026] The base plate 1 is symmetrically equipped with bearing seats 7 along its center. Each bearing seat 7 is rotatably equipped with a lead screw 8. The two lead screws 8 are fixedly connected by a coupling 9, and the threads on the two lead screws 8 are arranged in opposite directions. The lead screws 8 are arranged along the length direction of the first slide rail 4. A threaded sleeve 10 is installed on the outside of the lead screw 8. A push-pull plate 11 is fixedly installed on the outside of the threaded sleeve 10. One end of the push-pull plate 11 is fixedly connected to the first slide block 5. An adjusting motor 12 is also installed on the top of the base plate 1. The output shaft end of the adjusting motor 12 is shaft-connected to one end of the lead screw 8. When the adjustment motor 12 is started, the adjustment motor 12 will drive the lead screw 8 to rotate. The rotation of the lead screw 8 will drive the corresponding lead sleeve 10 to move. The lead sleeve 10 is connected to the corresponding first slide 5 through the push-pull plate 11. Therefore, when the lead sleeve 10 moves, it will drive the first slide 5 to move through the push-pull plate 11. Since the two lead screws 8 are set opposite to each other and the thread direction is opposite, the direction of movement of the lead sleeve 10 is always opposite. This can be used to adjust the distance between the two first slides 5.

[0027] A second slide rail 13 is also symmetrically installed on the base plate 1 along the center. The second slide rail 13 is parallel to the first slide rail 4. A second slide block 14 is slidably installed on the second slide rail 13. A stand 15 is fixedly installed on the top of the second slide block 14. A guide sleeve 16 is installed through the top of the stand 15 along the center.

[0028] Please see Figure 3-5 The feeding mechanism 3 includes two parallel long bars 17, which are fixedly connected by a crossbeam plate 18. Conveyor wheels 19 are rotatably mounted at the ends of the long bars 17, with the diameter of the conveyor wheels 19 being larger than the thickness of the long bars 17. Connecting shafts 20 are also provided near both ends of the long bars 17, with both ends of the connecting shafts 20 fixedly connected to the conveyor wheels 19. A conveyor belt 21 is also provided outside the long bars 17. A drive assembly 22 is installed at the bottom between the two long bars 17, driving the conveyor belt 21 to move outside the long bars 17. A feeding assembly 23 is installed at the end of the two long bars 17 away from the drive assembly 22, feeding the bent metal sheet. By driving the conveyor belt 21 to move outside the long bars 17 through the drive assembly 22, and placing the metal sheet on top of the conveyor belt 21, the moving feeding of the metal sheet can be achieved.

[0029] Several hanging plates are fixedly installed on the outer wall of the long rod 17. The bottom of the hanging plates protrudes from the bottom of the conveyor belt 21. A lifting plate 26 is fixedly installed between two opposite hanging plates. The middle part of the lifting plate 26 is fixedly installed on the output shaft end of the lifting cylinder 6. A stabilizing plate 24 is also installed between two opposite hanging plates. The stabilizing plate 24 is located directly above the upright frame 15. Guide rods 25 are symmetrically installed along the center of the bottom of the stabilizing plate 24. The bottom of the guide rods 25 passes through the guide sleeve 16. The lifting cylinder 6 can drive the long rod 17 to adjust its height by lifting the lifting plate 26, thereby adjusting the height of the metal plates on the conveyor belt 21 for easy loading and unloading. The guide rods 25 can cooperate with the guide sleeve 16 to improve the stability of the conveyor belt 21 during height adjustment.

[0030] Please see Figure 6 The drive assembly 22 includes vertical plates 27 fixedly mounted on the outer wall of the long bar 17. Two vertical plates 27 are fixedly connected at their bottom via a connecting plate 28. A conveyor shaft 29 is rotatably mounted between the two vertical plates 27. Conveyor rollers 30 are symmetrically mounted on the conveyor shaft 29 along its center. A conveyor belt 21 is located outside the conveyor rollers 30. A steering shaft 31 is also symmetrically mounted between the two vertical plates 27 along its center. A steering roller 32 is symmetrically mounted on the steering shaft 31 along its center. The outer wall of the steering roller 32 is tightly abutted against the outer wall of the conveyor belt 21. By driving the conveyor rollers 30 to rotate using the conveyor shaft 29, the conveyor rollers 30 can drive the conveyor belt 21 to move. The steering rollers 32 provide tension to the conveyor belt 21, ensuring stable driving of the conveyor belt 21 by the conveyor rollers 30.

[0031] A conveyor motor 33 is installed at the bottom between the two vertical plates 27. The output shaft of the conveyor motor 33 protrudes from one side of the vertical plate 27 and is fixedly mounted with a drive pulley 34. The end of the conveyor shaft 29 facing the output shaft of the conveyor motor 33 protrudes from the vertical plate 27 and is fixedly mounted with a driven pulley 35. The drive pulley 34 and the driven pulley 35 are connected by a transmission belt 36. An outer cover 37 is also fixedly mounted on the outer wall of the vertical plate 27, covering the outside of the transmission belt 36. When the conveyor motor 33 is started, it drives the driven pulley 35 to rotate through the drive pulley 34 and the transmission belt 36. The driven pulley 35 then drives the conveyor shaft 29 to rotate, thereby driving the conveyor belt 21.

[0032] Please see Figure 7The unloading assembly 23 includes a lifting frame 38 fixedly installed below the long bar 17. Both ends of the lifting frame 38 are fixedly connected to the bottom of the hanging plate. A horizontal plate 39 is fixedly installed on the top of the lifting frame 38, extending along the length of the long bar 17. Opposite end plates 40 are fixedly installed on the top of the horizontal plate 39. A screw 41 is rotatably installed between the end plates 40. A screw sleeve 43 is installed outside the screw 41, and a unloading plate 42 is fixedly installed outside the screw sleeve 43. The top of the unloading plate 42 protrudes from the top of the conveyor belt 21. Driving the screw 41 to rotate causes it to move the unloading plate 42 via the screw sleeve 43. The unloading plate 42 can then push the metal sheet on the conveyor belt 21 through its top, thus unloading the bent metal sheet.

[0033] A wear-resistant pad 44 is fixedly installed on the top outer wall of the feeding plate 42. A guide rail 45 is fixedly installed between the two end plates 40. A guide seat 46 is installed through the feeding plate 42. The guide seat 46 is slidably installed on the guide rail 45. A feeding motor 47 is installed at one end of the top of the horizontal plate 39. The output shaft end of the feeding motor 47 is connected to the screw 41.

[0034] Through the above-described solution of this utility model, the structure of this utility model is simple, practical and convenient. The distance between the two sets of feeding mechanisms 3 can be adjusted, so the distance between the two feeding mechanisms 3 can be changed according to the size of the metal sheet, thereby achieving a better feeding effect and improving stability. In addition, the unloading component 23 set inside the feeding mechanism 3 can perform auxiliary unloading operation after the metal sheet is bent, which facilitates unloading.
