Description

Technical Field

[0002] Metal pipes, as a common component, are widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other fields. In the process of mechanical manufacturing and processing, it is often necessary to drill holes in the pipes. Punching is much more efficient than drilling in terms of production efficiency and is also much cheaper.

[0003] For example, utility model patent CN216801320U discloses a punching device for metal pipes, which solves the problem of low production efficiency in existing metal pipe punching methods, which typically involve workers placing the metal pipe into a punching die and then manually feeding it.

[0022] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a punching device for metal pipe processing, including a workbench 1 and a pipe body 6. A C-shaped plate 4 is fixedly connected to the upper end of the workbench 1. A punching moving assembly 5 is provided on the workbench 1. The punching moving assembly 5 includes a rotating circular plate 512. A plurality of circumferentially distributed contact plates 514 are fixedly connected to the lower end of the rotating circular plate 512. A punching part 515 is fixedly connected to the front side of the lower end of each contact plate 514. A movable circular plate 510 is rotatably connected to the upper end of the rotating circular plate 512. A contact post 59 is fixedly connected to the middle of the upper end of the movable circular plate 510. The outer end of the contact post 59 is slidably connected to... A C-shaped plate 4 is connected to a contact post 59 that penetrates the C-shaped plate 4. Multiple circumferentially distributed insert posts 511 are fixedly connected to the outer side of the upper end of the rotating circular plate 512. The outer ends of the insert posts 511 are slidably connected to the C-shaped plate 4 and penetrate the C-shaped plate 4. A spring 513 is fixedly connected to the upper end of the movable circular plate 510. The upper end of the spring 513 is fixedly connected to the C-shaped plate 4. A cam 58 is abutted against the upper end of the contact post 59. A second rotating shaft 56 is scraped and connected to the surface of the cam 58 and penetrates the cam 58. Side plates 57 are rotatably connected to both sides of the second rotating shaft 56 through bearings. The lower end of each side plate 57 is fixedly connected to the C-shaped plate 4.

[0023] In this embodiment, a second pulley 55 is fixedly connected to the left side of the outer end of the second rotating shaft 56. A first pulley 53 is provided on the lower side of the front end of the second pulley 55. A belt 54 is sleeved between the first pulley 53 and the second pulley 55. A first rotating shaft 52 is fixedly connected to the surface of the first pulley 53, and the first rotating shaft 52 passes through the first pulley 53. The left end of the first rotating shaft 52 passes through the workbench 1 and is fixedly connected to the output end of the stepper motor 51. The outer end of the stepper motor 51 is fixedly connected to the workbench 1. An incomplete gear 516 is fixedly connected to the middle of the outer end of the rotating shaft 52. A rack 517 is meshed with the lower end of the incomplete gear 516. An inner limiting plate 518 is fixedly connected to the lower end of the rack 517.

The output ends of electric push rods 521 are fixedly connected to both sides of the lower end of the outer limiting plate 522. The lower end of the electric push rods 521 is slidably connected to the worktable 1.

[0024] Specifically, the first rotating shaft 52 is driven to rotate by the output end of the stepper motor 51, which in turn drives the incomplete gear 516 to rotate. At this time, the incomplete gear 516 drives the rack 517 to perform intermittent movement. At this time, the rack 517 drives the inner limit plate 518 of the pipe fitting 6, the outer limit plate 522 of the pipe fitting, and the electric push rod 521 to move.

[0025] In this embodiment, a limiting hole 7 is provided in the middle of the front end of the workbench 1, and a fixing plate 519 is fixedly connected to the front end of the rack 517. A limiting post 520 is fixedly connected to one end of the fixing plate 519 near the workbench 1, and the limiting hole 7 is slidably connected to the outer end of the limiting post 520.

[0026] Specifically, the rack 517 drives the fixed plate 519 to move, which in turn drives the limiting post 520 to move within the limiting hole 7.

[0027] In this embodiment, a passage groove 8 is provided on the upper left side of the C-shaped plate 4, and the belt 54 is disposed in the passage groove 8 on the side near the second pulley 55.

[0028] Specifically, a groove 8 is provided to prevent interference between the belt 54 and the C-shaped plate 4.

[0029] In this embodiment, each corner of the lower end of the workbench 1 is fixedly connected to a bracket 2, and each bracket 2 is fixedly connected to an anti-slip pad 3 at its lower end.

[0030] Specifically, the support bracket 2 and the anti-slip pad 3 can be used to provide stable support for the workbench 1.

[0031] In this embodiment, the outer diameter of the limiting post 520 is the same as the inner diameter of the limiting hole 7, and the length of the limiting post 520 is less than the depth of the limiting hole 7.

[0032] Specifically, ensure that the limiting post 520 does not interfere with the limiting hole 7.

[0033] In this embodiment, the lower end of the inner limiting plate 518 of the pipe fitting is arranged in an arc shape, and the upper end of the outer limiting plate 522 of the pipe fitting is arranged in an arc shape.

[0034] Specifically, ensure that the inner limiting plate 518 and the outer limiting plate 522 of the pipe fitting do not interfere with each other when they come into contact with the pipe fitting body 6.

[0035] In this embodiment, the end of the first rotating shaft 52 away from the stepper motor 51 is rotatably connected to the worktable 1 via a bearing.

[0036] Specifically, ensure that the first rotating shaft 52 does not interfere with the worktable 1.

[0037] Working principle: When using the device, first place the pipe body 6 onto the outer limiting plate 522, then push the pipe body 6 forward. Next, power the electric push rod 521 through an external power source. The output end of the electric push rod 521 will drive the outer limiting plate 522 and the pipe body 6 to move upward. When the inner end of the pipe body 6 contacts the inner limiting plate 518, stop powering the electric push rod 521. Then, power the stepper motor 51 through an external power source. The output end 51 drives the first rotating shaft 52 to rotate, which in turn drives the first pulley 53 to rotate. At this time, the first rotating shaft 52 drives the incomplete gear 516 to rotate, which in turn drives the rack 517 to move back intermittently. At this time, the rack 517 indirectly drives the pipe body 6 to move back intermittently. At this time, the rack 517 drives the fixed plate 519 and the limiting post 520 to move. The limiting post 520 slides in the limiting hole 7. During this process, the first pulley 53 drives the second pulley 55 to rotate through the belt 54. The movement then drives the second rotating shaft 56 to rotate, which in turn drives the cam 58 to rotate. The cam 58 then contacts the contact post 59, which in turn drives the moving circular plate 510, rotating circular plate 512, insert post 511, contact plate 514, and punching component 515 to reciprocate downwards. The punching component 515 punches holes in the outer end of the pipe body 6 during the movement. When it is necessary to change the diameter of the hole punched in the pipe body 6, the pipe body 6 can be removed first. Manually move the rotating disc 512 downwards. This causes the moving disc 510 to move downwards, which in turn moves the contact post 59 downwards. At this time, the spring 513 is stretched. After the insertion post 511 is no longer in contact with the C-shaped plate 4, rotate the rotating disc 512 by 120°. Then release the operation on the rotating disc 512. At this time, all components return to their original positions. This utility model enables punching of holes with different inner diameters in the pipe body 6, improving the applicability of the device.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
