Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a zero-tailing laser tube cutting machine. Background Technology

[0002] Laser cutting machines focus a laser beam emitted from a laser source into a high-power-density beam. This beam is then directed onto the workpiece surface, and the movement of the beam relative to the workpiece creates a kerf, thus achieving the cutting purpose. However, ordinary laser tube cutting machines suffer from material waste due to excess material.

[0003] Chinese patent CN202210311566.0 discloses a two-chuck side-mounted laser tube cutting machine, including a bed assembly, a rear chuck assembly, a gantry cutting system assembly, a front chuck assembly, a follower material support assembly, a follower front receiving assembly, a chain feeding assembly, and a machine head sheet metal assembly. All other components are mounted on the bed assembly. A limit block is installed on the side of the bed near the guide rail, and a sheet metal assembly of the bed and an electrical control box is installed on the side of the bed near the limit block. This invention can achieve cutting and processing of various tube materials, reducing material waste.

[0004] However, this technical solution aims to solve the problem of pipe clamping stability by allowing both the front and rear chucks to move, thus achieving a more stable clamping of the pipe. The cutting station is located at the end of the front chuck that is far from the rear chuck. Based on this structure and cutting method, it is impossible to effectively reduce waste of tail material or truly achieve zero tail material. For example, it has technical problems such as the tail material not being able to continue to be pushed due to the length of the chuck itself, making it difficult to make full use of the tail material. Summary of the Invention

[0005] One of the objectives of this invention is to address the shortcomings of existing technologies by providing a zero-tail-material laser tube cutting machine. This machine utilizes a linearly moving rear chuck assembly relative to the front chuck assembly to push or pull the tubes into place. The laser tube cutting assembly's movement path crosses both ends of the front chuck assembly to form two cutting stations. The front and rear chuck assemblies work together to double-clamp the tubes, enabling the initial pushing of the tube to the first cutting station for cutting, and the subsequent pulling of the remaining material to the second cutting station for cutting. This maximizes the utilization of the tail material, achieves shorter tail lengths, and even truly achieves zero tail material.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A zero-tailing laser tube cutting machine includes a frame; it also includes a front chuck module mounted on the frame; and a rear chuck module and a laser tube cutting module that are linearly movable respectively, wherein the front end of the linear movement path of the rear chuck module is matched and connected to the front chuck module, and the linear movement path of the laser tube cutting module extends to both ends of the front and rear ends of the front chuck module respectively, thereby forming a first cutting station at the front end of the front chuck module and a second cutting station between the front chuck module and the rear chuck module.

[0008] During the cutting process, the pipe is pushed forward by the rear chuck module, double-clamped by the front and rear chuck modules, and cut by the laser cutting module at the first cutting station. When the length of the pipe extending beyond the front end of the front chuck module is less than the required length, the pipe is pulled back by the rear chuck module, double-clamped by the front and rear chuck modules, or clamped by the front chuck module alone, and cut by the laser cutting module at the second cutting station.

[0009] As an improvement, both the front chuck module and the rear chuck module include a clamping assembly for holding the pipe fitting and a rotating assembly for driving the pipe fitting to rotate.

[0010] As an improvement, the front chuck module includes a roller assembly for supporting and guiding the pipe fitting.

[0011] As an improvement, a first receiving station is formed below the front end of the front chuck module, and a second receiving station is formed below the rear end.

[0012] As an improvement, the rear end of the linear movement path of the rear chuck module is the feeding end of the pipe fitting, and this end is matched with a support component to support the pipe fitting.

[0013] As an improvement, the support assembly includes a support wheel having a support surface that matches the shape of the pipe fitting, on which the pipe fitting is mounted.

[0014] As an improvement, the frame is provided with a first slide rail and a first slide block slidably mounted on the first slide rail along the X-axis direction. The rear chuck module is mounted on the first slide block, and the frame also includes a first linear drive component that drives the first slide block to slide. The frame is provided with a second slide rail and a second slide block slidably mounted on the second slide rail along the X-axis direction. The second slide block is provided with a Z-axis drive component and a Y-axis drive component of a three-axis drive module, and the frame also includes a second linear drive component that drives the second slide block to slide.

[0015] As an improvement, the first linear drive assembly includes a first rack mounted on the frame and arranged parallel to the first slide rail, and a first drive unit mounted on the first slide block, wherein the drive end of the first drive unit is connected to a gear that meshes with the first rack.

[0016] As an improvement, the second linear drive assembly includes a second rack mounted on the frame and arranged parallel to the second slide rail, and a second drive unit mounted on the second slide block, wherein the drive end of the second drive unit is connected to a gear that meshes with the second rack.

[0017] As an improvement, the laser tube cutting machine is configured with a horizontal structure, and the front chuck module, rear chuck module and laser tube cutting module are all located on the top surface of the frame.

[0018] As an improvement, the laser tube cutting module includes a laser tube cutting assembly and a rotary drive assembly that drives the laser tube cutting assembly to oscillate along a plane formed by the X-axis and Z-axis. The laser tube cutting module rotates and oscillates to perform beveling on the tube.

[0019] As an improvement, the rotation axis of the rotary drive assembly is set along the Y-axis.

[0020] As an improvement, the laser tube cutting module further includes a three-axis drive module that drives the laser tube cutting assembly to move along the X, Y, and Z axes. The three-axis drive module is mounted on the frame, the rotary drive assembly is mounted on the drive free end of the three-axis drive module, and the laser tube cutting assembly is mounted on the drive free end of the rotary drive assembly.

[0021] As an improvement, the linear movement paths of the rear chuck module and the laser tube cutting module are arranged side by side and both are set along the X-axis direction.

[0022] The beneficial effects of this utility model are as follows:

[0023] (1) This utility model sets a linearly moving rear chuck assembly relative to the front chuck assembly to push or pull the tubes, and sets the moving path of the laser tube cutting assembly to cross the front and rear ends of the front chuck assembly to form two cutting stations. With the front and rear chuck assemblies, the tubes are double-clamped or the tail section is only clamped by the front chuck assembly. This enables the tubes to be pushed to the first cutting station for cutting at the beginning and pulled to the second cutting station for cutting when there is a tail section. This maximizes the use of tail material, achieves shorter tail material, or even truly achieves zero tail material.

[0024] (2) The present invention uses the front and rear chucks to clamp the pipe parts as close as possible to the cutting parts of the laser pipe cutting assembly, so that the cutting is more stable and the cutting accuracy is higher.

[0025] (3) This utility model can achieve beveling by setting a laser tube cutting component that can rotate and swing, thereby meeting a variety of processing needs, with good adaptability and low cost.

[0026] In summary, this utility model has the advantages of truly zero waste material, high cutting stability, and meeting various processing needs. Attached Figure Description

[0035] Example 1

[0036] like Figures 1-2 As shown, a zero-tailing laser tube cutting machine includes a frame 1; it also includes a front chuck module 2, which is mounted on the frame 1; and a rear chuck module 3 and a laser tube cutting module 4, which are linearly movable respectively. The front end of the linear movement path of the rear chuck module 3 is matched and connected to the front chuck module 2, and the linear movement path of the laser tube cutting module 4 extends to the front and rear ends of the front chuck module 2 respectively, thereby forming a first cutting station 101 at the front end of the front chuck module 2 and a second cutting station 102 between the front chuck module 2 and the rear chuck module 3.

[0037] Of course, depending on the user's overall functional requirements for the pipe cutting machine and economic cost considerations, the front chuck module 2 can be fixedly or movably installed on the frame 1.

[0038] During the cutting process, the pipe fitting 10 is pushed forward by the rear chuck module 3, and is double-clamped by the front chuck module 2 and the rear chuck module 3, and is cut by the laser pipe cutting module 4 at the first cutting station 101.

[0039] When the length of the pipe fitting 10 extending beyond the front end of the front chuck module 2 is less than the required length, the pipe fitting 10 is pulled back by the rear chuck module 3 for feeding, and is double-clamped by both the front chuck module 2 and the rear chuck module 3, or only clamped by the front chuck module 2, and then cut by the laser pipe cutting module 4 at the second cutting station 102. At this time, by pulling the pipe fitting 10 back by the rear chuck module 3, more of the pipe fitting 10 can extend from the rear section of the front chuck module 2 for cutting into the required length. Due to this cutting method of the tail section, the front and rear chuck modules can clamp only a small portion of the remaining pipe length, thus meeting the minimum length for stable clamping.

[0040] In some embodiments, particularly when the length of the pipe between the front chuck module 2 and the rear chuck module 3 is greater than or equal to 1 times the required length but less than 2 times the required length, especially when the rear chuck module 3 is inconvenient to clamp the pipe 10 or clamping affects the cutting quality of the pipe 10, the pipe 10 can be pushed forward by the rear chuck module 3 to the front chuck module 2 and then retracted. The pipe 10 is then clamped only by the front chuck module 2, and the end of the pipe 10 is cut by the laser pipe cutting module 4. Therefore, the pipe material can be utilized to the maximum extent, resulting in shorter tail material or even truly zero tail material.

[0041] It should be further explained that during the cutting operation, the length of the pipe fitting 10 extending to the corresponding cutting station should be matched with the required length as mentioned above. That is, the pipe fitting should extend as long as it needs to be cut, so that the clamping part of the chuck on the pipe fitting 10 is as close as possible to the cutting part, thereby making the cutting more stable and the cutting accuracy higher.

[0042] As an improvement, such as Figure 3 , 5 As shown, both the front chuck module 2 and the rear chuck module 3 include a clamping component 21 for clamping the pipe fitting 10 and a rotating component 22 for driving the pipe fitting 10 to rotate.

[0043] As an improvement, such as Figure 4 As shown, the front chuck module 2 includes a roller assembly 23 for supporting and guiding the pipe fitting 10.

[0044] In this embodiment, the clamping assembly 21, rotating assembly 22, and roller assembly 23 all adopt conventional structures of the prior art. For example, both the clamping assembly 21 and the roller assembly 23 adopt a four-jaw chuck structure. The difference between the two structures is that... Figure 3 As shown, the clamping end of the clamping assembly 21 is a fixedly installed clamping block 211, which clamps and fixes the pipe fitting 10 radially and axially, as shown. Figure 4As shown, the clamping end of the roller assembly 23 is a rotatable roller 231, which radially clamps the pipe fitting 10 and is axially movable. Figure 3 , 5 As shown, the rotating assembly 22 includes a rotating drive unit 221 and a gear disk 222. The gear at the drive end of the rotating drive unit 221 meshes with the gear disk 222 for transmission. A clamping structure for clamping the pipe 10 is connected to the gear disk 222. The clamping structure first clamps the pipe 10 and then rotates with the gear disk 222.

[0045] As an improvement, such as Figure 2 As shown, a first receiving station 201 is formed at the lower front end of the front chuck module 2, and a second receiving station 202 is formed at the lower rear end.

[0046] As an improvement, such as Figures 5-6 As shown, the frame 1 is provided with a first slide rail 11 along the X-axis and a first slide block 12 slidably mounted on the first slide rail 11. The rear chuck module 3 is mounted on the first slide block 12, and the frame 1 also includes a first linear drive component 14 for driving the first slide block 12 to slide. The frame 1 is provided with a second slide rail 15 along the X-axis and a second slide block 16 slidably mounted on the second slide rail 15. The second slide block 16 is provided with a Z-axis drive component and a Y-axis drive component of a three-axis drive module 43, and the frame 1 also includes a second linear drive component 17 for driving the second slide block 16 to slide.

[0047] As an improvement, the first linear drive assembly 14 includes a first rack 141 mounted on the frame 1 and arranged parallel to the first slide rail 11, and a first drive part 142 mounted on the first slide block 12. The drive end of the first drive part 142 is connected to a gear that meshes with the first rack 141.

[0048] As an improvement, the second linear drive assembly 17 includes a second rack 171 mounted on the frame 1 and arranged parallel to the second slide rail 15, and a second drive unit 172 mounted on the second slide block 16. The drive end of the second drive unit 172 is connected to a gear that meshes with the second rack 171.

[0049] As an improvement, the linear movement paths of the rear chuck module 3 and the laser tube cutting module 4 are arranged side by side and both are set along the X-axis direction.

For the sake of simplicity, only the differences between this embodiment and the above embodiments are described below. The difference between this embodiment and the above embodiments is that:

[0052] like Figure 6 As shown, as an improvement, the laser tube cutting module 4 includes a laser tube cutting assembly 41 and a rotation drive assembly 42 that drives the laser tube cutting assembly 41 to swing along the plane formed by the X-axis and Z-axis. The laser tube cutting module 4 rotates and swings to perform beveling on the tube 10.

[0053] In this embodiment, the laser tube cutting assembly 41 is rotatable and swingable, thereby realizing beveling, meeting a variety of processing needs, and is highly adaptable and low in cost.

[0054] As an improvement, the rotation axis of the rotary drive assembly 42 is set along the Y-axis.

[0055] As an improvement, the laser tube cutting module 4 further includes a three-axis drive module 43 that drives the laser tube cutting assembly 41 to move along the X, Y, and Z axes.

[0056] As an improvement, both the rotary drive assembly 42 and the three-axis drive module 43 adopt conventional structures of the prior art. For example, the rotary drive assembly 42 can be set as a rotary motor, with the output end of the rotary motor connected to the swing frame, and the laser tube cutting assembly 41 is installed on the swing frame; the three-axis drive module 43 adopts a sliding structure composed of linear slide rail and slider in combination with a drive structure composed of rotary motor, gear and rack.

[0064] Work process:

[0065] During the initial cutting, the pipe 10 is fed from the rear end of the rear chuck module 3 and supported by the support component 5. The rear chuck module 3 clamps the pipe 10 and pushes it forward to the front end of the front chuck module 2, with the extension length matching the required cutting length. The front and rear chucks clamp the pipe 10 simultaneously. The laser pipe cutting module 4 cuts and / or processes the pipe at the first cutting station 101 and unloads it from the first receiving station 201.
