Description

Technical Field

[0001] This utility model relates to the field of bending machines, specifically to an arc-shaped bending machine. Background Technology

[0002] A bending machine is a machine that can bend thin sheets. When bending metal sheets, different bending machines are selected according to requirements. Some require bending the sheet into angular shapes, while others require bending into curved surfaces. When bending metal sheets into curved surfaces, traditional bending machines generally use pressure rollers arranged in a triangle. Two rollers support the sheet, while the third roller is responsible for pressing. They work together to form the curved surface of the metal sheet. This type of bending machine generally relies on a single pressure roller for bending metal sheets, resulting in relatively low forming efficiency and relatively cumbersome and time-consuming loading and unloading processes.

[0028] The utility model will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0029] Please see Figure 1-4 According to an embodiment of the present invention, a circular arc bending machine includes a machine body 1. A table 2 is fixedly installed on the top of the machine body 1. A support component 3 is symmetrically installed on the top of the table 2 along its center. An extension frame 5 is fixedly installed on the middle of one side of the machine body 1 along its length direction. A conveying component 6 is installed on the top of the extension frame 5. The conveying component 6 is positioned above the center of the top of the table 2. A bending component 4 is fixedly installed on the side of the top of the table 2 away from the extension frame 5. The raw material metal sheet is conveyed to the support component 3 on the top of the table 2 by the conveying component 6. Then, the bending component 4 is adjusted to move toward the table 2 to perform the bending operation on the metal sheet. After bending, the sheet is sent back in the opposite direction by the conveying component 6.

[0030] An outer cover 7 is fixedly installed on the outside of the extension frame 5, and a frame 8 is fixedly installed on the top outer side of the platform 2. Infrared sensors 9 are fixedly installed on the two inner side walls of the frame 8 facing the extension frame 5. The infrared sensors 9 can detect human body temperature to prevent workers from putting their hands into the frame 8 when the bending assembly 4 is working, thus improving safety. The bottom of the machine body 1 is equipped with a traveling wheel 10, and the side of the traveling wheel 10 is also provided with a support foot 11 installed at the bottom of the machine body 1. The traveling wheel 10 can facilitate the subsequent movement of the entire bending machine, while the support foot 11 can be positioned after movement.

[0031] The first hydraulic cylinder 12 is symmetrically installed inside the body 1 along the center. The bottom of the first hydraulic cylinder 12 is hinged to the body 1. The outer cover 7 has a notch 13 on the side facing the body 1. The body 1 also has a maintenance door 14 on the side away from the extension frame 5.

[0032] The support assembly 3 includes a support frame 15 fixedly installed on the top of the platform 2. A support plate 16, arranged along the width direction of the platform 2, is fixedly installed on the top of the support frame 15. A first circular block 17, arranged along its length direction, is fixedly installed on the top of the support plate 16. A side plate 19 is installed on the side of the support plate 16 away from the center of the platform 2 via a hinge shaft 18. A second circular block 20 is fixedly installed on the top of the side plate 19. The second circular block 20 is parallel to the first circular block 17. A through-hole 21 is symmetrically opened on the platform 2 along its center. The output shaft end of the first hydraulic cylinder 12 passes through the through-hole 21 and is hinged to the bottom center of the side plate 19. The conveying assembly 6 conveys the metal sheet to the first circular block 17. When the bending assembly 4 presses down on the middle of the metal sheet, the second circular block 20 on the side plate 19 can move toward the first circular block 17 by activating the first hydraulic cylinder 12, thereby assisting in bending and forming the metal sheet and improving bending efficiency.

[0033] Limiting brackets 22 are fixedly installed at the two corners of the top of the platform 2 near the infrared sensor 9. The limiting brackets 22 can limit the overall length of the metal plate. Baffles 23 are symmetrically installed on the top of the platform 2 near the bending assembly 4. The baffles 23 can prevent the metal plate from moving to the installation position of the bending assembly 4.

[0034] A vertical plate 24 is fixedly installed at the center of the top of the platform 2 away from the extension frame 5. A vertically arranged slide rail 25 is fixedly installed on the side of the vertical plate 24 facing the extension frame 5. A slider 26 is slidably installed on the slide rail 25. A height limiting needle 27 is fixedly installed on the slider 26. The height limiting needle 27 can limit the height of the conveying component 6 during adjustment to avoid collision with the bending component 4.

[0035] A stand 28 is fixedly installed at the center of the top of the platform 2 near the extension frame 5. A clamping cylinder 29 is fixedly installed on one side of the top of the stand 28, and a clamping plate 30 is fixedly installed at the end of the output shaft of the clamping cylinder 29. When the conveying assembly 6 conveys the metal plate to the support assembly 3, the clamping cylinder 29 can drive the clamping plate 30 to move. The clamping plate 30 pushes the side of the metal plate to move until the other side of the metal plate is tightly against the baffle 23, thereby achieving the positioning of the metal plate.

[0036] Please see Figure 5 The bending assembly 4 includes an assembly frame 31 fixedly installed on the top of the platform 2. A top plate 32 is fixedly installed on the top of the assembly frame 31, positioned directly above the center of the platform 2. A second hydraulic cylinder 33 is installed at the top center of the top plate 32. The output shaft end of the second hydraulic cylinder 33 passes through the top plate 32 and is fixedly installed with a lifting plate 34. A mounting frame 35 is fixedly installed at the bottom of the lifting plate 34. A bending roller 36 is installed on the mounting frame 35, and the bending roller 36 is arranged along the length direction of the first circular block 17. When the second hydraulic cylinder 33 is activated, it can drive the lifting plate 34 to adjust its height. This causes the lifting plate 34 to move the mounting frame 35 and the bending roller 36 at its bottom toward the platform 2 until the bending roller 36 contacts the metal plate, thus cooperating with the first circular block 17 and the second circular block 20 to perform a bending operation on the metal plate.

[0037] A first guide sleeve 37 is installed through the top plate 32, and a first guide rod 38 is fixedly installed on the top of the lifting plate 34, with the top of the first guide rod 38 passing through the first guide sleeve 37. The assembly between the first guide rod 38 and the first guide sleeve 37 can make the lifting plate 34 more stable when it is raised and lowered.

[0038] Please see Figure 6-8 The conveying assembly 6 includes a lifting assembly fixedly installed on the top of the extension frame 5. A strip frame 39 is fixedly installed on the top of the lifting assembly. Upright blocks 40 are symmetrically installed at both ends and the middle of the strip frame 39. The top end of the upright block 40 protrudes from the top of the strip frame 39. A crossbeam 41 is fixedly installed on the top of the upright block 40. One end of the crossbeam 41 facing the bending assembly 4 is located above the platform 2. Conveying wheels 42 are rotatably installed at both ends of the crossbeam 41. The conveying wheels 42 located near the strip frame 39 are connected by a connecting shaft 43. A conveyor belt 44 is provided on the outside of the crossbeam 41. The conveyor belt 44 is installed on the outside of the crossbeam 41 through the conveyor wheels 42. The metal sheet is placed on the conveyor belt 44, and the connecting shaft 43 is driven to rotate, which drives the conveyor wheel 42 located near the strip frame 39. This causes the conveyor belt 44 to move outside the crossbeam 41, thus conveying the metal sheet. After the metal sheet is bent and formed, the connecting shaft 43 is rotated in the opposite direction to transport the metal sheet back.

[0039] A lifting frame 45 is fixedly installed at one bottom end of the strip frame 39. A motor 46 is mounted on the lifting frame 45. A drive pulley 47 is fixedly installed at the end of the output shaft of the motor 46. A driven pulley 48 is fixedly installed at the end of the connecting shaft 43 near the motor 46. The drive pulley 47 and the driven pulley 48 are connected by a transmission belt 49. The motor 46 can drive the drive pulley 47 to rotate, and the drive pulley 47 can then drive the driven pulley 48 to rotate through the transmission belt 49, thereby realizing the rotation adjustment of the connecting shaft 43.

[0040] The lifting assembly includes a fixed plate 51 fixedly installed at the top center of the extension frame 5. A lifting cylinder 52 is installed at the bottom of the fixed plate 51. The output shaft end of the lifting cylinder 52 passes through the fixed plate 51 and is fixedly installed with a lifting plate 50. The lifting plate 50 is fixedly installed at the bottom center of the strip frame 39. The height of the strip frame 39 can be adjusted by the lifting cylinder 52, thereby enabling the metal plate to be accurately delivered to the support assembly 3.

[0041] A stabilizing plate 53 is symmetrically installed at the bottom of the strip frame 39 along its center. A second guide rod 54 is fixedly installed at the bottom of the stabilizing plate 53. An installation plate 55 is symmetrically installed at the top of the extension frame 5 along its center. A second guide sleeve 56 is installed through the installation plate 55. The bottom of the second guide rod 54 passes through the second guide sleeve 56. The arrangement of the second guide rod 54 and the second guide sleeve 56 can make the strip frame 39 more stable when it is raised and lowered.

[0042] A height limiting frame 57 is also fixedly installed at the end of the side wall of the crossbeam 41 located near the middle of the strip frame 39. The height limiting frame 57 is located near the upright plate 24. By using the height limiting frame 57 and the height limiting pin 27, the lifting height of the strip frame 39 can be limited.

[0043] Through the above-described solution of this utility model, the side plate 19 is provided on the side of the support plate 16, and the second circular block 20 provided on the side plate 19 can cooperate with the bending roller 36 to assist in bending the metal plate, thereby improving the bending efficiency.
