Description

Technical Field

[0001] This utility model relates to the field of pipe punching waste removal technology, and in particular to a pipe punching waste removal device. Background Technology

[0002] The tubing used in automotive chassis is usually variable cross-section irregular tubing. These irregular tubing often use internal high-pressure forming in production. When punching the tubing, the die needs to be completely fitted to the curved surface to ensure the shearing quality. However, due to the complexity of the internal structure of the irregular tubing, and the fact that the inside of the tubing is hollow (especially the irregular cross-section), traditional dies cannot provide support from the back of the workpiece, making it difficult to install rigid dies. Customizing punching dies for this type of tubing is extremely costly and has poor versatility. Therefore, dies are usually not used when punching variable cross-section irregular tubing.

[0003] However, the punching waste generated during pipe punching often cannot fall off directly; instead, the edges remain adhered to the inner wall of the pipe. After punching, an additional process is required to remove the punching waste. Traditional methods for handling punching waste mostly involve manually removing the waste pieces by inserting tools into the pipe. However, in practice, manually removing punching waste with tools still has the following drawbacks:

[0004] Manually removing punching waste is inefficient and energy-inefficient during mass production, which affects delivery.

[0005] Because the waste material is located on the inner wall of the pipe fittings, manual removal requires manually inserting a tool into the pipe fittings to locate and remove the waste material. However, due to the varying diameters of the pipe fittings, when the inner diameter of the pipe fittings is not large enough, it is difficult for workers to get a good view after inserting their arms into the pipe fittings, making it difficult to locate the punching waste material. This results in a longer operation time and affects production efficiency.

[0006] Since punching involves cutting through the pipe wall, the edges of the punching waste may be quite sharp. Removing the waste by manually inserting an arm into the pipe carries certain risks and could potentially cause cuts to workers.

[0007] Semi-automated methods for removing punching waste typically involve inserting a pry bar into the pipe to peel off the waste. However, the peeled waste falls inside the pipe, and after the pry bar is removed, workers still need to place the pipe vertically or at an angle to allow the waste to slide out. This method is inconvenient and the production efficiency is still not high enough. On the other hand, when the pipe is too long to be placed vertically or at an angle, workers still need to reach inside the pipe to remove the waste, which is inefficient and carries the risk of injuring workers.

[0008] Based on this, those skilled in the art have proposed a device for removing waste material from pipe punching, which provides a new solution to the above-mentioned technical problems. Utility Model Content

[0009] Therefore, it is necessary to provide a pipe punching waste removal device to address the problems raised in the background art.

A second baffle plate is fixed to the bottom of the installation cylinder near the waste material transfer tank. The bottom end face of the second baffle plate is attached to the inner wall of the waste material transfer tank. A second material receiving chamber is formed between the second baffle plate, the waste material transfer tank, the first baffle plate, and the second material receiving port. A material discharge opening is provided on the side of the waste material transfer tank away from the second material receiving opening.

[0017] Preferably, a third baffle plate is fixed on the side of the waste transfer tank away from the receiving port 2. The third baffle plate is inclined towards the receiving port 2, and the second baffle plate, the waste transfer tank, the first baffle plate, the third baffle plate and the receiving port 2 form a receiving chamber 2.

[0018] Preferably, a connecting rod is rotatably connected to the top of the waste transfer tank on the side away from the third baffle plate. A movable collection plate is fixed to the outside of the connecting rod. The movable collection plate is rotatably connected to the waste transfer tank through the connecting rod.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0034] Example 1

[0035] Please refer to Figure 1-6 The present invention provides a pipe punching waste removal device including a base plate 1, a push cylinder 2 installed at one end of the base plate 1, an installation plate 3 fixed at the output end of the push cylinder 2, the push cylinder 2 is used to push the installation plate 3 to move, the installation plate 3 is slidably connected to the top of the base plate 1, a motor 4 is installed on the installation plate 3, a transmission shaft 5 is fixedly connected at the output end of the motor 4, the motor 4 is used to drive the transmission shaft 5 to rotate, a waste removal component is installed at the end of the transmission shaft 5, when the transmission shaft 5 rotates, it can drive the waste removal component to rotate, and the waste inside the pipe is scraped off by the rotation of the waste removal component. A pipe placement rack 7 for placing pipes is fixed at the end of the waste removal component away from the push cylinder 2. When removing waste, the worker places the pipe to be processed on the pipe placement rack 7 and faces the opening end closer to the waste towards the waste removal component.

[0036] It should be noted that the length of drive shaft 5 is not limited when using it; the length of drive shaft 5 can be set according to actual needs.

[0037] It should be noted that, in another embodiment, the drive shaft 5 can be configured as a rod with a telescopic length to accommodate waste removal work at different depths.

[0038] Please refer to Figure 1-6 The waste removal assembly includes a connecting collar 13 fixed to the end of the drive shaft 5 and a scraper plate 6 connected to the connecting collar 13. When the drive shaft 5 rotates, it will drive the connecting collar 13 to rotate. At the same time, the connecting collar 13 will drive the scraper plate 6 to rotate. The scraper plate 6 scrapes off the waste through its rotation. The scraper plate 6 is located at its top close to the inner wall of the pipe to facilitate better scraping of waste.

[0039] Please refer to Figure 1-2 The material removal plate 6 is welded onto the connecting collar 13.

[0040] Example 2

[0041] Please refer to Figure 3An adjusting screw 14 is rotatably connected to the end of the connecting collar 13 away from the drive shaft 5. The material removal plate 6 is threaded onto the adjusting screw 14. Guide rods are fixed on the connecting collar 13 and located on both sides of the adjusting screw 14. The material removal plate 6 is slidably connected to the outside of the guide rods. The height of the material removal plate 6 relative to the drive shaft 5 can be adjusted by adjusting the screw 14, thereby adapting to the removal of waste materials of different pipe diameters. Adjustment is only required by rotating the adjusting screw 14. The guide rods play a guiding role when the material removal plate 6 moves, preventing it from rotating with the adjusting screw 14. When the connecting collar 13 rotates with the drive shaft 5, the guide rods and adjusting screw 14 can drive the material removal plate 6 to rotate synchronously. The position of the material removal plate 6 can be made more stable through the action of the guide rods and adjusting screw 14.

[0042] Example 3

[0043] Please refer to Figure 4 A waste box 11 is located at the top of the base plate 1 and at the end of the pipe placement rack 7 near the drive shaft 5. The waste box 11 is used to collect waste. A receiving hopper 12 is fixed below the descraping plate 6 and above the connecting collar 13. A receiving port is formed between the top of the receiving hopper 12 and the descraping plate 6, and a receiving chamber is formed inside the receiving hopper 12. In use, the pipe fitting with the punched holes facing upwards is first placed on the pipe placement rack 7. Then, the drive shaft 5 is moved by the motor 4 to a position where the receiving port is offset from the position of the punched waste. This position is set as the initial position of the descraping plate 6. First, the push cylinder 2 then moves the receiving hopper 12 towards the waste material to a position below or to the side of the waste material. Then, the motor 4 is started to drive the scraper plate 6 to rotate towards the receiving port 1, scraping the waste material down and causing it to fall into the inside of the receiving hopper 12. Then, the push cylinder 2 is started again to drive the drive shaft 5 to gradually pull out from inside the pipe and move it above the waste box 11. Then, the motor 4 is started again to drive the scraper plate 6 and the receiving hopper 12 to rotate through the drive shaft 5, causing the waste material in the receiving hopper 12 to fall into the inside of the waste box 11 for unified collection.

[0044] It should be noted that in another embodiment, when the inner diameter of the pipe is small and the opening of the receiving port is required to be large to better receive the scraped waste, if the receiving hopper 12 rotates gradually from the side of the waste towards the direction closer to the waste following the removal plate 6, the edge of the receiving port may contact the waste first, causing the waste to be scraped off before the removal plate 6. In this case, the waste cannot fall into the inner side of the receiving hopper 12. Therefore, in this embodiment, the pipe fitting with the punch facing upwards is first placed on the pipe placement rack 7, and then the motor 4 drives the transmission shaft 5 to move to the receiving port. The direction of the waste inside the pipe fitting is set as the initial position two of the material removal plate 6. Then, the push cylinder 2 pushes the receiving hopper 12 to move towards the waste direction, so that the waste is located inside the receiving port. Then, the motor 4 is started to drive the material removal plate 6 to rotate and scrape off the waste, so that the waste falls into the inside of the receiving hopper 12. Then, the push cylinder 2 is started again to drive the transmission shaft 5 to gradually pull out from inside the pipe fitting and move to above the waste box 11. Then, the motor 4 is started again to drive the material removal plate 6 and the receiving hopper 12 to rotate through the transmission shaft 5, so that the waste in the receiving hopper 12 falls into the inside of the waste box 11 for unified collection.

[0045] In this second embodiment, the movement of the receiving hopper 12 in its radial plane during the waste collection process is as follows: the receiving hopper 12 starts to rotate from the initial position one or the initial position two to scrape off the waste, then the receiving hopper 12 rotates again to make the waste fall into the waste box 11, and then the receiving hopper 12 rotates again to return to the initial position one or the initial position two.

[0046] Example 4

[0047] Please refer to Figure 5-6 A mounting sleeve 17 is sleeved on the outside of the drive shaft 5. A connecting frame 18 is fixed at the end of the mounting sleeve 17 away from the connecting collar 13. The mounting sleeve 17 is fixedly connected to the mounting plate 3 through the connecting frame 18. The drive shaft 5 can be rotatably connected to the mounting sleeve 17 or can be mutually non-contact with the mounting sleeve 17. The presence of the mounting sleeve 17 does not interfere with the rotation of the drive shaft 5, and the mounting sleeve 17 remains stationary when the drive shaft 5 rotates.

[0048] A first baffle plate 15 is fixed to the end of the connecting collar 13 away from the mounting cylinder 17. A descrambling plate 6 is fixedly connected to the top of the first baffle plate 15. A waste transfer tank 16 is fixed to one end of the first baffle plate 15, located outside the connecting collar 13. A receiving port 2 is formed between the top side of the waste transfer tank 16 and the descrambling plate 6. A second baffle plate 19 is fixed to the bottom of the mounting cylinder 17 near the waste transfer tank 16. The bottom end face of the second baffle plate 19 is attached to the inner wall of the waste transfer tank 16 or forms a small gap with the inner wall of the waste transfer tank 16. This gap is not large enough for waste to pass through. The second baffle plate 19 and the waste transfer tank 16 are connected. 6. A receiving chamber two is formed between the first baffle plate 15 and the receiving port two. A discharge opening 26 is provided on the side of the waste transfer tank 16 away from the receiving port two. The first baffle plate 15 serves to connect the connecting collar 13, the removal plate 6, and the waste transfer tank 16, and also serves to prevent waste from splashing out when it falls into the waste transfer tank 16. In use, the operator first places the pipe fitting with the punch facing upwards on the pipe placement rack 7, and then drives the drive shaft 5 to rotate away from the receiving port two by starting the motor 4, so that the removal plate 6 is offset from the waste when viewed along the axis of the drive shaft 5. This position can be set as the removal port two. The material plate 6 is initially positioned three times. Then, by activating the push cylinder 2, the waste transfer tank 16 and the material removal plate 6 are moved towards the waste direction, so that the material removal plate 6 is positioned to the side of the waste. Next, the motor 4 is activated, causing the material removal plate 6 to rotate towards the receiving port two, scraping off the waste. The waste falls into the inside of the waste transfer tank 16. When the material removal plate 6 is in its initial position, the second baffle plate 19 is located on the side of the discharge opening 26 near the receiving port two. The waste falling into the inside of the waste transfer tank 16 is blocked by the second baffle plate 19, the connecting collar 13, the waste transfer tank 16, and the first baffle plate 15, thus falling into the receiving chamber two. Then, the push... The air cylinder 2 is restarted, driving the transmission shaft 5 to gradually pull out from inside the pipe and move above the waste box 11. Then the motor 4 is restarted, driving the removal plate 6 and the waste transfer tank 16 to rotate towards the initial position of the removal plate 6 through the transmission shaft 5. This causes the second baffle plate 19 to rotate relative to the waste transfer tank 16. At the same time, the discharge opening 26 gradually rotates towards the receiving chamber 2 and gradually enters the receiving chamber 2. As the area of ​​the discharge opening 26 in the receiving chamber 2 gradually increases, the waste will fall from the discharge opening 26 into the waste box 11 for unified collection as the removal plate 6 returns to the initial position 3.

[0049] In this embodiment, the movement of the waste transfer tank 16 in its radial plane during the waste collection process is as follows: the waste transfer tank 16 starts to rotate from the initial position three to scrape off the waste, and then the waste transfer tank 16 rotates again to return to the initial position three. During this process, the waste automatically falls into the waste box 11 for collection. Compared with the design of embodiment three, the process of sending the waste into the waste box 11 for collection in this embodiment is simpler.

[0050] Example 5

[0051] Please refer to Figure 6 A third baffle plate 25 is fixed on the side of the waste transfer tank 16 away from the receiving port 2. The third baffle plate 25 is inclined towards the receiving port 2. The second baffle plate 19, the waste transfer tank 16, the first baffle plate 15, the third baffle plate 25 and the receiving port 2 form a receiving chamber 2. The setting of the third baffle plate 25 can effectively prevent waste from falling into the receiving chamber 2 and popping out from the opening on the side of the waste transfer tank 16 and the dewatering plate 6 away from the receiving port 2.

[0052] Example 6

[0053] Please refer to Figure 6 A connecting rod 22 is rotatably connected to the top of the waste transfer tank 16 on the side away from the third baffle plate 25. A movable collection plate 20 is fixed to the outside of the connecting rod 22. The movable collection plate 20 is rotatably connected to the waste transfer tank 16 through the connecting rod 22. When the connecting rod 22 rotates, the movable collection plate 20 will rotate with the connecting rod 22. One end of the connecting rod 22 passes through the first baffle plate 15 and is fixed with an adjusting rod 21. A positioning screw 23 is inserted into the inner side of the adjusting rod 21 away from the connecting rod 22. Several positioning holes 24 adapted to the positioning screws 23 are opened on the first baffle plate 15. By moving the adjusting rod 21, the connecting rod 22 can be rotated, which in turn drives the movable collection plate 20 to rotate. The position of the adjusting rod 21 can be positioned by the positioning screws 23 and the positioning holes 24, thereby positioning the position of the movable collection plate 20. The setting of the movable collection plate 20 can prevent some waste from deviating from the receiving port when it falls, and can better remove punching waste.

[0054] Example 7

[0055] Please refer to Figure 1-2 A mounting bracket 8 is installed on the top of the base plate 1 and at one end of the pipe placement rack 7. A positioning cylinder 9 is installed on the top of the mounting bracket 8. A positioning pressure block 10 is fixedly connected to the output end of the positioning cylinder 9. The pipe fittings on the top of the pipe placement rack 7 are positioned by the positioning cylinder 9 and the positioning pressure block 10.

[0056] The specific working principle of the pipe fitting punching waste removal device provided by this utility model is as follows:

[0057] When using this pipe fitting waste punching device, the operator first places the pipe fitting with the punch facing upwards on the pipe placement rack 7. Then, the positioning cylinder 9 is activated, driving the positioning block 10 to descend and positioning the pipe fitting. Next, the motor 4 drives the transmission shaft 5 and the waste removal plate 6 to rotate, so that the waste removal plate 6 is in its initial position. Then, the push cylinder 2 is activated to push the waste removal plate 6 towards the waste, so that the waste removal plate 6 is on the side of the waste. Then, the motor 4 is activated to drive the waste removal plate 6 to rotate towards the waste, scraping off the waste. After the waste falls, it falls into the receiving chamber one or receiving chamber two. Then, the push cylinder 2 is activated again, driving the receiving chamber one or receiving chamber two to be gradually pulled out from the inside of the pipe fitting and moved above the waste box 11. Then, the motor 4 is activated again, driving the waste removal plate 6 to rotate through the transmission shaft 5, so that the waste falls into the waste box 11 for unified collection. After that, the waste removal plate 6 is reset.
