Description

Technical Field

[0001] The present invention relates to the field of combined punching devices for PVC pipes, and more particularly, to a combined punching device on a PVC pipe production line. Background Art

[0002] Punched PVC pipes play a significant role in ventilation. In building ventilation systems, it is very common to install them on walls or ceilings. These carefully arranged small holes become the key channels for indoor and outdoor air exchange. The dirty indoor air can be discharged, and the fresh outdoor air can flow in smoothly, thus effectively improving the indoor air quality and creating a healthy and comfortable breathing environment for people. In some breeding places, punched PVC pipes also show their great capabilities. The breeding animals are dense, and there are high requirements for air circulation. The punched PVC pipes can continuously ventilate and exhaust, disperse odors, moisture and harmful gases, provide fresh and clean air for the breeding animals, help the healthy growth of animals, reduce the risk of diseases, and provide a solid guarantee for the good development of the breeding industry.

[0003] Today's PVC pipe punching devices generally adopt a multi-group combined drill bit design in pursuit of high efficiency. Although this design greatly improves the punching efficiency, it significantly increases the overall load on the device. During the punching operation, multiple drill bits operate simultaneously, generating stronger friction with the PVC pipe material and imposing a great pressure on the overall structure of the device. More seriously, once the drill bit wears during the punching process, the situation will deteriorate further. The worn drill bit cannot maintain the accurate cutting angle and force, resulting in more energy consumption during punching, further increasing the load on the device and accelerating the wear process of the entire device. Frequent wear not only increases the equipment maintenance cost but also may lead to a decline in punching quality.

[0004] How to invent a combined punching device on a PVC pipe production line to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0031] The bottom of the down-drilling shaft 14 is fixedly connected with a mounting seat 141. A drill bit is installed at the bottom of the mounting seat 141. A connecting block 100 is fixedly connected to the inner side wall of the drilling seat 10. A fixed sleeve 101 is fixedly connected to the connecting block 100. The fixed sleeve 101 is rotatably connected to the up-drilling shaft 15.

The push seat 20 is located below the rotating seat 19. The rotating seat 19 is slidably arranged with the push seat 20.

[0032] It should be noted that when performing the drilling operation on the pipe, first start multiple first motors 7. The transmission belt 9 drives multiple second transmission wheels 11 to rotate, drives the up-drilling shaft 15 to rotate, drives the down-drilling shaft 14 to rotate through the plug-in part 143, thereby driving the bottom drill bit to rotate. Then start the fourth motor 41. By driving the threaded rod 42 to rotate, drive the connecting frame 4 and the main bracket 5 to move downward, drive multiple drilling seats 10 to move downward, and drill the pipe through multiple drill bits, completing the work of drilling the pipe.

[0033] Refer to Figure 5 - Figure 7 As shown in the figure, the clamping assembly includes a support seat 30 fixedly connected to the top of the frame 2. A clamping block 31 is rotatably connected to the side wall of the support seat 30. The clamping block 31 is arranged in a conical shape. Multiple cylinders 32 are fixedly connected to the side wall of the frame 2. A reciprocating rod 33 is arranged at the top of the cylinder 32. The top end of the reciprocating rod 33 is fixedly connected with a bracket 34. A fixed frame 35 is fixedly connected to the top of the frame 2. A moving plate 36 is slidably arranged on the top of the fixed frame 35. A third motor 39 is fixedly connected to the top of the moving plate 36. A second motor 37 is fixedly connected to the side wall of the fixed frame 35. The output end of the second motor 37 is fixedly connected with a lead screw 38. The bottom of the moving plate 36 is in threaded fit connection with the lead screw 38. The output end of the third motor 39 is fixedly connected with a clamping block 31. A pipe is arranged on one side of the clamping block 31. The power assembly includes a fourth motor 41 fixedly connected to the bottom of the frame 2. The top of the fourth motor 41 is fixedly connected with a threaded rod 42. The threaded rod 42 is in threaded fit connection with the connecting frame 4.

[0034] It should be noted that by starting the second motor 37, the second motor 37 drives the lead screw 38 to rotate, drives the moving plate 36 and the third motor 39 to move towards the clamping block 31, drives the clamping block 31 connected to the third motor 39 to move towards the pipe, and clamps the pipe.

[0035] If holes are drilled at different positions in the circumferential direction of the pipe, first control the air cylinder 32 to drive the bracket 34 to move downward through the reciprocating rod 33 to prevent the bracket 34 from interfering with the pipe. Then start the third motor 39. The third motor 39 drives the clamping block 31 to rotate, driving the pipe to rotate by a fixed angle. Then control the bracket 34 to move upward to support the bottom of the pipe, and then perform the drilling operation, so that holes can be drilled in the circumferential direction of the pipe.

[0036] In this embodiment, first place the pipe above the bracket 34. By starting the second motor 37, the second motor 37 drives the lead screw 38 to rotate, driving the third motor 39 and the clamping block 31 on the moving plate 36 to move towards the pipe to clamp the pipe. Then start multiple first motors 7 to make the upper drill shaft 15 drive the lower drill shaft 14 to rotate, thereby driving the bottom drill bit to rotate. Finally, start the fourth motor 41. The main bracket 5 moves downward through the threaded rod 42, driving multiple drilling seats 10 to move downward, and drilling the pipe through multiple drill bits, completing the work of drilling the pipe.

[0037] When the drill bit is worn due to long-term work, the downward force required for the drill bit to drill the pipe increases, and the reaction force of the pipe on the drill bit increases. This reaction force is transmitted to the rotating seat 19 and the hard spring 18 through the push seat 20 on the lower drill bit, overcoming the elastic force of the hard spring 18, causing the rotating seat 19 to move upward, contacting the upper third wire 24, making the alarm lamp 21 and the battery in the battery compartment 22 in an electrically connected state, lighting the alarm lamp 21, reminding the staff that the drill bit is worn and needs to be replaced in time to prevent the problem that the wear of the drill bit is aggravated and affects the drilling quality.

[0038] It should be noted that by setting the adjusting seat 16, when the adjusting seat 16 is rotated, the pressure of the adjusting seat 16 on the hard spring 18 can be adjusted. By adjusting this pressure, the staff can freely control the trigger threshold of the alarm lamp 21 within a certain range. When the pressure of the adjusting seat 16 on the hard spring 18 is reduced, the alarm lamp 21 can be triggered when the wear of the drill bit is relatively light, which can reduce the problem that the wear of the device is accelerated due to multiple drill bits working simultaneously.

[0039] In summary, by setting the reminder component, when the drill bit is worn, the rotating seat 19 moves upward, lighting the alarm lamp 21, reminding the staff that the drill bit is worn and needs to be replaced in time, which can avoid the problem that the drilling load increases due to multiple drill bits wearing simultaneously, resulting in earlier overall wear aggravation of the device.

[0040] It should be noted that the specific model specifications of the motor need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
