Description

Technical Field

[0001] This utility model relates to the technical field of feeding structures, specifically to a feeding structure for a pipe cutting machine. Background Technology

[0002] Traditional laser tube cutting machines have overly simplistic tube positioning and alignment mechanisms, which can easily lead to positioning deviations and inaccurate alignment. This is especially true in the field of single-chuck small-tube laser tube cutting machines, where the tubes are small and the single-chuck main unit is short, making the requirements for tube positioning and alignment in the feeding section even higher.

[0003] The announcement number CN210387979U discloses an automatic feeding tube laser cutting device, including a frame. On the frame, a feeding mechanism, a tube clamping mechanism, a laser cutting mechanism, and a chip removal mechanism are arranged sequentially according to the tube processing order. The feeding mechanism includes a storage plate, a lifting belt, a feeding trough, and a feeding trolley. The lifting belt lifts and transports the tube to the feeding trough, and the feeding trolley pushes it forward. The tube clamping mechanism includes a support base and a tube sleeve for clamping and rotating the tube. The laser cutting mechanism includes a displacement mechanism in at least the longitudinal direction and a laser head, with the laser head aligned with the front end of the tube. The chip removal mechanism includes a mounting plate, a slide table, a slider connector, and a chip removal tube. The top of the front end of the chip removal tube has a notch, the direction of which corresponds to the laser cutting direction. It moves along the slide table and extends into the tube, thus realizing automatic tube feeding.

[0004] In the pipe processing process, it is often necessary to position the angle of the pipe. However, in the aforementioned automatic feeding laser cutting device, the pipe tends to tumble on the equipment during feeding, making it impossible to position the pipe's angle and causing inconvenience in production. Therefore, the existing technology has the problem of not being able to position the pipe's angle. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a pipe cutting machine feeding structure, which includes a frame and a material pulling mechanism. This pipe cutting machine feeding structure has the advantage of being able to position the angle of the pipe.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] A pipe cutting machine feeding structure includes a frame and a pulling mechanism. The pulling mechanism is mounted on the frame, and a connecting frame is fixedly connected to the frame. A height limiting plate is mounted on the connecting frame, and a feeding channel is provided between the height limiting plate and the frame. The feeding channel connects to the pulling mechanism. A pressure plate is slidably connected to the connecting frame, and a first driving component is provided between the pressure plate and the connecting frame. A connecting seat is mounted on the frame, and a second driving component is fixedly mounted on the connecting seat. The second driving component has a stop bar located at the feeding channel, and the output end of the second driving component is connected to the stop bar and drives the stop bar to move. This design, with the height limiting plate, restricts the angle of the workpiece as it moves within the feeding channel, ensuring the workpiece is at a suitable angle and achieving the advantage of angle positioning for the pipe. It also ensures the stability of the number of pipes fed, enabling sequential feeding of each pipe.

[0008] Preferably, the connecting seat is slidably connected to the frame, and the sliding direction of the connecting seat on the frame is parallel to the extension direction of the feeding channel. The frame is rotatably connected to a rotating shaft, and a gear is fixedly installed on the rotating shaft. The connecting seat is fixedly connected to a rack that meshes with the gear, and a locking assembly is provided between the frame and the rotating shaft. With this configuration, by sliding the connecting seat on the frame, the second driving component and the stop lever are moved, and the initial position of the stop lever is adjusted so that the stop lever can adapt to pipes of different widths.

[0009] Preferably, a height limiting block is installed on the side of the height limiting plate closest to the feeding channel, and the height limiting block protrudes from the edge of the height limiting plate toward the feeding channel. This arrangement improves the positioning accuracy of the pipe.

[0010] Preferably, the feeding channel is inclined. This configuration allows the pipe to move within the feeding channel without requiring an additional power source.

[0011] Preferably, the height limiting block has an inclined surface, the lower end of which is inclined towards the feeding channel. This design prevents the pipe from getting stuck in the feeding channel during positioning and correction, improving the stability and reliability of the equipment operation.

[0012] Preferably, the lower end of the feeding channel is provided with a feeding port, which is vertically arranged. This vertical arrangement allows the pipe to be redirected from its direction of movement and disengaged from the stop bar when it moves into the feeding port, thus facilitating the delivery of the pipe to the processing equipment.

[0013] Preferably, the orientation of the first driving member is parallel to the extension direction of the feeding channel. With this configuration, the first driving member can drive the stop bar to move along the extension direction of the feeding channel, allowing the pipe to move more stably with the stop bar within the feeding channel.

[0014] Preferably, the material pulling mechanism includes a first drive shaft, a drive assembly, and multiple material pulling belts. The first drive shaft is rotatably connected to the frame, and multiple pulleys are fixedly mounted on the first drive shaft. One end of each material pulling belt is fixed to the frame, and the other end is wound around a pulley. Each of the multiple material pulling belts corresponds one-to-one with a specific pulley. The drive assembly is connected to the first drive shaft. This configuration enables the material pulling mechanism to convey pipes into the feeding channel.

[0015] Preferably, the material pulling mechanism further includes a second drive shaft, which is rotatably connected to the frame and parallel to the first drive shaft. Multiple guide wheels are fixedly mounted on the second drive shaft, and the material pulling belt is wound around the guide wheels, with each guide wheel corresponding to one of the multiple material pulling belts. This arrangement guides the movement of the material pulling belt and prevents the material pulling belt and the pipe from swaying.

[0016] Preferably, the drive assembly includes a third drive component, a reducer, a drive sprocket, a driven sprocket, and a chain. The reducer is mounted on a frame, the third drive component is mounted on the reducer and its output shaft is fixedly connected to the reducer's input shaft, the drive sprocket is fixedly mounted on the reducer's output shaft, the driven sprocket is fixedly mounted on a first transmission shaft, and the chain is wound around the drive sprocket and the driven sprocket. This configuration enables the drive assembly to rotate the first transmission shaft.

[0017] Compared with the prior art, this utility model has achieved beneficial technical effects:

[0018] 1. By setting the height limit plate, the angle of the workpiece can be restricted during the movement of the pipe in the feeding channel, so that the workpiece is at a suitable angle and the angle of the workpiece can be positioned. This achieves the advantage of being able to position the angle of the pipe, and is especially suitable for use on single chuck small pipe cutting machines.

[0019] 2. The height limit plate can block the pipes in the width direction of the feeding channel, preventing the plates in the feeding channel from being arranged in the width direction of the feeding channel, thereby enabling the pipes to be fed one by one and ensuring the stability of the number of pipes fed.

[0020] 3. The second pipe in the feeding channel is pressed by the pressure plate so that only the first pipe can fall on the stop bar. The second driving component drives the stop bar and the first pipe to move, so that the first pipe moves to the processing equipment, thereby realizing the feeding of pipes one by one.

Detailed Implementation

[0028] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.

[0029] Example 1:

[0030] refer to Figure 1 and Figure 2A feeding structure for a pipe cutting machine includes a frame 11 and a feeding mechanism, which is mounted on the frame 11. The feeding mechanism includes a first drive shaft 13, a drive assembly, and multiple feeding belts 12. The first drive shaft 13 is rotatably connected to the frame 11.

Multiple guide wheels 16 are fixedly mounted on the second drive shaft 15, and the feeding belts 12 are wound around the guide wheels 16. Each feeding belt 12 corresponds one-to-one with a specific guide wheel 16. The drive assembly includes a third drive component 21, a reducer 22, a drive sprocket 23, a driven sprocket 24, and a chain 25. The reducer 22 is mounted on the frame 11. The third drive component 21 is mounted on the reducer 22, and the output shaft of the third drive component 21 is fixedly connected to the input shaft of the reducer 22. The third drive component 21 is powered by a motor. The drive sprocket 23 is fixedly mounted on the output shaft of the reducer 22, the driven sprocket 24 is fixedly mounted on the first drive shaft 13, and the chain 25 is wound around the drive sprocket 23 and the driven sprocket 24.

[0031] refer to Figure 3 and Figure 4 A frame 11 is fixedly connected to a connecting frame 31, and multiple connecting frames 31 are provided. A height limiting plate 32 is installed on the connecting frame 31, and a feeding channel 33 is provided between the height limiting plate 32 and the frame 11. The height limiting plate 32 is slidably connected to the frame 11, and the width of the feeding channel 33 can be adjusted by sliding the height limiting plate 32, thereby accommodating pipes of different widths and improving applicability. The feeding channel 33 is connected to a pulling mechanism. A pressure plate 41 is slidably connected to the connecting frame 31, and a first driving component 42, which is a first cylinder, is provided between the pressure plate 41 and the connecting frame 31. The orientation of the first driving component 42 is parallel to the extension direction of the feeding channel 33. A height limiting block 34 is installed on the side of the height limiting plate 32 near the feeding channel 33, and the height limiting block 34 protrudes from the edge of the height limiting plate 32 toward the feeding channel 33. The feeding channel 33 is inclined. The height limiting block 34 has an inclined surface 35, and the lower end of the inclined surface 35 is inclined toward the direction close to the feeding channel 33. The height limiting block 34 is rotatably connected to the height limiting plate 32. By rotating the height limiting block 34 on the height limiting plate 32, the distance by which the height limiting block 34 protrudes into the feeding channel 33 can be adjusted, thereby accommodating pipes of different sizes and improving applicability. The lower end of the feeding channel 33 is provided with a feeding port 36, which is vertically arranged.

[0032] A connecting seat 51 is mounted on the frame 11, and a second driving component 52, which is a second cylinder, is fixedly mounted on the connecting seat 51.

The locking assembly 57 is a worm gear reducer, and the rotating shaft 54 ​​is fixedly connected to the output shaft of the worm gear reducer. The rotating shaft 54 ​​cannot drive the worm gear reducer to rotate. When it is necessary to drive the rotating shaft 54 ​​to rotate, the input shaft of the worm gear reducer is rotated, thereby enabling the rotating shaft 54 ​​to rotate through the worm gear reducer. When it is not necessary to rotate the rotating shaft 54, the worm gear reducer achieves self-locking, thus locking the rotating shaft 54.

[0033] Specific work process:

[0034] The pipe to be processed is placed on the pulling mechanism, which feeds the pipe into the feeding channel 33 and moves it away from the pulling mechanism within the channel. During its movement within the feeding channel 33, the pipe first comes into contact with the height limiting plate 32. The height limiting plate 32 positions the pipe and ensures that pipes at the height limiting plate 32 can only be arranged sequentially along the extension direction of the feeding channel 33, preventing two pipes from being placed side-by-side within the channel and providing some degree of angle positioning. The pipe continues to move radially within the feeding channel 33, coming into contact with the height limiting block 34. The height limiting block 34 further positions the pipe's angle, resulting in more precise angle positioning. The first driving component 42 drives the pressure plate 41 to press the second pipe, and the second pipe blocks the pipes behind it, so that only the first pipe falls on the stop bar 53. The second driving component 52 drives the stop bar 53 and the first pipe to continue to move downward, so that the pipe falls onto the processing equipment along the feeding channel 33 and the feeding port 36, realizing the feeding function. The processing equipment drives the pipe to move axially, so that the workpiece moves axially and leaves the feeding channel 33 during the processing and unloading process.

[0035] When it is necessary to feed more material into the processing equipment, the second drive component 52 drives the stop lever 53 back to its original position, and the first drive component 42 drives the pressure plate 41 to release the pipe, allowing the pipe in the feeding channel 33 to slide onto the stop lever 53. Then, the first drive component 42 drives the pressure plate 41 to press the second pipe at this time, and the second pipe blocks the pipe behind it. The second drive component 52 drives the stop lever 53 to move downward, thereby realizing the function of cyclic feeding.

[0036] This embodiment has the following advantages:

[0037] By setting the height limit plate 32, the angle of the workpiece can be limited by the height limit plate 32 during the movement of the pipe in the feeding channel 33, so that the workpiece is at a suitable angle and the angle of the workpiece can be positioned, thus achieving the advantage of being able to position the angle of the pipe.

[0038] The height restriction plate 32 can block the pipe in the width direction of the feeding channel 33, preventing the plates in the feeding channel 33 from being arranged in the width direction of the feeding channel 33, thereby enabling the pipe to be fed one by one and ensuring the stability of the number of pipes fed.

[0039] The second pipe in the feeding channel 33 is pressed by the pressure plate 41, so that only the first pipe can fall on the stop bar 53. The second driving component 52 drives the stop bar 53 and the first pipe to move, so that the first pipe moves to the processing equipment, thereby realizing the feeding of pipes one by one.

[0040] During the production process, it is often necessary to process pipes of different widths. By sliding the connecting seat 51 on the frame 11, the second driving component 52 and the stop bar 53 are moved, and the initial position of the stop bar 53 is adjusted so that it can adapt to pipes of different widths. When the width of the pipe increases, the sliding connecting seat 51 and the stop bar 53 move away from the pressure plate 41 to prevent the pressure plate 41 from pressing the first pipe while pressing the second pipe. When the width of the pipe decreases, the sliding connecting seat 51 and the stop bar 53 move closer to the pressure plate 41 to increase the contact area between the pressure plate 41 and the second pipe, preventing the pressure plate 41 from failing to press the second pipe.

[0041] The drive shaft 54 ​​rotates, which in turn drives the connecting seat 51 to slide on the frame 11 via the gear 55 and rack 56, thus enabling the connecting seat 51 to move. After the position of the connecting seat 51 is adjusted, the locking component 57 locks the drive shaft 54 ​​onto the frame 11 to prevent the connecting seat 51 from moving accidentally.

[0042] By setting the height limit block 34, the angle of the pipe can be further positioned, thereby improving the positioning accuracy of the pipe.

[0043] By tilting the feeding channel 33, the pipes inside the feeding channel 33 can slide down under the action of gravity, and the pipes can move within the feeding channel 33 without the need for an additional power source.

[0044] By setting the inclined surface 35, the pipe comes into contact with the inclined surface 35 during its movement in the feeding channel 33, allowing the pipe to slide relative to the inclined surface 35 and for the inclined surface 35 to push and correct the angle of the pipe, thereby improving the smoothness of the pipe's movement, preventing the pipe from getting stuck in the feeding channel 33 during positioning and correction, and improving the stability and reliability of the equipment operation.

[0045] The vertically positioned feed port 36 allows the pipe to slide down onto the processing equipment under gravity. Furthermore, the feed port 36 extends in a different direction than the feed channel 33, allowing the pipe to change direction and disengage from the stop bar 53 when it moves into the feed port 36 following the stop bar 53, thus facilitating the delivery of the pipe to the processing equipment.

[0046] The first driving component 42 can drive the stop bar 53 to move along the extension direction of the feeding channel 33, so that the pipe can move more stably with the stop bar 53 in the feeding channel 33, improve the stability of the pipe when it moves in the feeding channel 33, and ensure the accuracy of the angle when the pipe moves to the processing equipment.

[0047] The workpiece is placed on the pull belt 12, causing the pull belt 12 to hang downwards under the pressure of the workpiece. When it is necessary to feed the pipe into the feeding channel 33, the drive assembly drives the first transmission shaft 13 to rotate and the pulley 14 to rotate. The pulley 14 pulls the pull belt 12, causing the pull belt 12 to have an upward tension. The pull belt 12 then moves the pipe upwards to the feeding channel 33, allowing the pipe to roll into the feeding channel 33, thus realizing the function of feeding the pipe into the feeding channel 33 through the pull mechanism.

[0048] The guide wheel 16 changes the extension direction of the pulling belt 12, which guides the movement of the pulling belt 12, so that the pulling belt 12 can accurately transport the pipe into the feeding channel 33, and can prevent the pulling belt 12 and the pipe from shaking.

[0049] The motor drives the drive sprocket 23, chain 25 and driven sprocket 24 to rotate through the reducer 22, thereby driving the first drive shaft 13 to rotate through the driven sprocket 24, thus realizing the function of driving the first drive shaft 13 to rotate through the drive assembly.

[0050] Example 2:

[0051] refer to Figure 5 A pipe cutting machine feeding structure differs from Embodiment 1 in that: a swing arm 61 is rotatably connected to the second drive shaft 15, the swing arm 61 is located at the upper end of the feeding channel 33 and is used to block the pipe. A drive cylinder 62 is provided between the swing arm 61 and the frame 11, and the drive cylinder 62 extends and retracts to drive the swing arm 61 to rotate on the second drive shaft 15.

[0052] This embodiment has the following advantages:

[0053] When it is not necessary to feed pipes into the feeding channel 33, the drive cylinder 62 drives the swing arm 61 to rotate towards the feeding channel 33, blocking the pipes and preventing excessive pressure on the pipes that would cause the pressure plate 41 to fail to clamp them. When it is necessary to feed pipes into the feeding channel 33, the drive cylinder 62 drives the swing arm 61 to rotate away from the feeding channel 33, preventing the swing arm 61 from blocking the pipes.
