Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting, and in particular relates to a steel pipe laser cutting system. Background Art

[0002] At present, there are many ways to cut steel pipes, including gas cutting, circular saw cutting, band saw cutting, pipe cutter cutting, laser cutting, water jet cutting, grinding wheel saw cutting, friction saw cutting, shear cutting, etc. Among them, sawing is the most common cutting method, but this cutting method is inefficient, and the saw blade is expensive, easy to wear, long replacement time, and labor-intensive. Compared with sawing, laser cutting can greatly reduce costs and improve efficiency, especially for difficult-to-cut materials such as chromium, laser cutting has more obvious advantages in cutting efficiency and cost.

[0003] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to melt, vaporize, ablate or reach the ignition point quickly, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. In the field of industrial processing, the application of laser cutting of steel pipes is becoming more and more extensive, but the existing laser cutting equipment can usually only clamp one steel pipe at a time, and it must cooperate with the rotation drive of the steel pipe, which is difficult to adapt to the production rhythm and affects the cutting efficiency. In addition, the laser cutting equipment occupies a large area and requires a large investment in the production site. Therefore, there is an urgent need for a laser cutting system for steel pipe production lines to improve cutting efficiency and reduce production costs. Utility Model Content

[0010] As a further improvement of the present invention, the angle between the light-emitting axis and the vertical direction is not greater than 45°.

[0011] As a further improvement of the present invention, the support assembly includes at least two rollers whose axes extend along the second direction and are spaced apart in the first direction.

[0012] As a further improvement of the utility model, the steel tube laser cutting system further includes at least one clamping mechanism;

[0013] The clamping mechanism includes two clamping members arranged opposite to each other in the second direction, and a driving member is arranged corresponding to at least one of the clamping members, so that the distance between the two clamping members can be adjusted by the driving member accordingly to clamp or release the steel pipe to be cut along the second direction.

[0014] As a further improvement of the utility model, the clamping mechanism is arranged on a support platform, and the support platform is located on a side of the laser cutting device close to the support assembly.

[0039] Example:

[0040] See also Figure 1~Figure 5 The steel pipe laser cutting system in the preferred embodiment of the utility model includes a support assembly 2 and a laser cutting device 3.

[0041] In a preferred embodiment, the axial direction of the steel pipe 1 to be cut when placed and cut is referred to as the first direction, and the horizontal direction perpendicular to the first direction is referred to as the second direction.

[0042] Specifically, the support assembly 2 in the preferred embodiment includes a plurality of components correspondingly arranged in the first direction, and a bearing position extending along the first direction is formed above the plurality of components to bear the steel pipe 1 to be cut.

[0043] In actual settings, the bearing position formed on the support assembly 2 preferably has a width along the second direction that is not less than twice the outer diameter of the steel pipe 1, so that the bearing position can bear at least two side-by-side steel pipes 1, thereby achieving simultaneous loading and continuous cutting of multiple steel pipes 1 at the cutting position.

[0044] Preferably, a frame is provided below the support assembly 2 , and the frame is provided with workstations for arranging several components of the support assembly 2 in a first direction.

[0045] In a specific preferred embodiment, the support assembly 2 includes at least two rollers 21 whose axes extend along the second direction and are spaced apart in the first direction. By using the spaced apart arrangement of the rollers 21 in the first direction, a bearing position extending along the first direction can be formed to realize the bearing and transportation of the steel pipe 1 to be cut.

[0046] Preferably, each roller 21 can be respectively arranged at a station of the frame.

[0047] In actual configuration, a driving mechanism is provided corresponding to at least one roller 21 for driving it to rotate around an axis, thereby realizing the transportation of the steel pipe 1 carried by the roller 21 .

[0048] Preferably, in actual configuration, the aforementioned driving mechanism is preferably a motor, and the motor may drive the roller 21 directly or indirectly (eg, belt drive, gear drive, etc.).

[0049] Meanwhile, in actual setting, at least part of the rollers 21 match with the driving mechanism to become driving wheels; at least part of the rollers 21 can rotate around the axis to become driven wheels during the transportation of the steel pipe 1.

[0050] Furthermore, the steel tube laser cutting system in the preferred embodiment further comprises at least one clamping mechanism 4, which can clamp the steel tube 1 along the second direction to ensure the reliability of the setting state of the steel tube 1 during the laser cutting process.

[0051] Specifically, the clamping mechanism 4 in the preferred embodiment includes two clamping members 41 arranged opposite to each other in the second direction, and a driving member 42 is provided corresponding to at least one of the clamping members 41, so that the distance between the two clamping members 41 can be adjusted accordingly by the driving member 42 to clamp the steel pipe 1 to be cut along the second direction or release the clamping.

[0052] For example, in Figure 4 In the preferred embodiment shown, a driving member 42 is provided for each of the two clamping members 41 , and the driving member 42 is further preferably a cylinder or a linear motor.

[0053] Furthermore, the clamping member 41 is preferably a clamping plate, and the height of the clamping plate is preferably greater than the radius of the steel pipe 1, so that the two clamping plates can act on the two sides of the steel pipe 1 with the largest width along the second direction respectively to enhance the clamping effect of the clamping plate on the steel pipe 1.

[0054] In more detail, it is preferred that the opposite end faces of the clamping plate are set as wedge-shaped faces or arc-shaped faces to increase the contact area between the clamping plate and the outer peripheral wall of the steel pipe 1 when clamping the steel pipe 1, thereby improving the clamping effect. Figure 4 In the preferred embodiment shown, the portion of the clamping plate that is higher than the radius of the steel pipe 1 is configured as a wedge-shaped structure or an arc-shaped structure that is wider at the top and narrower at the bottom.

[0055] In a preferred embodiment, the clamping mechanism 4 is disposed on a supporting platform 5 , and the supporting platform 5 is located on a side of the laser cutting device 3 close to the supporting assembly 2 .

[0056] More specifically, if Figure 1 As shown in , in a preferred embodiment, the support platform 5 is arranged between the laser cutting device 3 and the roller 21, so that it can reliably support the end of the steel pipe 1 when the laser cutting device 3 is working.

[0057] In another preferred embodiment, a support platform 5 (not shown in the figure) is also preferably provided on the side of the laser cutting device 3 away from the support assembly 2, which is used to clamp and fix the cut portion of the steel pipe 1 to facilitate subsequent processing of the cut steel pipe 1.

[0058] like Figure 1 As shown in the figure, the laser cutting device 3 in the preferred embodiment is located on one side of the bearing position along the first direction, and includes a laser cutting unit 31 and a displacement mechanism 32 that are assembled in combination. The laser cutting unit 31 can reciprocate along the second direction driven by the displacement mechanism 32 and cut the steel pipe 1.

[0059] In actual setting, the displacement mechanism 32 is preferably a truss manipulator, which includes a slide rail mechanism and a power mechanism extending along the second direction. The laser cutting unit 31 is matched with the slide rail mechanism and can be driven by the power mechanism to perform reciprocating motion.

[0060] Furthermore, the laser cutting unit 31 in the preferred embodiment is used to generate a laser beam that can penetrate and cut two layers of the steel pipe wall at the same time, so as to cut the steel pipe 1.

[0061] At the same time, if Figure 5 As shown in the figure, in order to prevent the slag produced in the upper cutting part from falling to the lower cutting part and affecting the cutting quality of the lower cutting part, the light output axis 311 of the laser beam is set to be oblique in the preferred embodiment, so that in the movement direction of the laser cutting unit 31, the lower cutting part produced by the action of the light output axis 311 and the steel pipe 1 is in front of the upper cutting part.

[0062] For example, in Figure 5In the preferred embodiment shown, the movement direction of the laser cutting unit 31 is from the right to the right. At this time, the light-emitting axis 311 of the laser cutting unit 31 forms an angle α with the vertical direction. It can be seen that the top of the light-emitting axis 311 is deflected from right to left by an angle α. In this way, the intersection A below the steel pipe 1 is always located in front of the intersection B between the light-emitting axis 311 and the upper intersection B of the steel pipe 1. In this case, when the upper intersection B is being cut, the steel pipe directly below it has been cut. In this way, the slag generated in the upper part of the steel pipe 1 during the cutting process can be prevented from dripping into the uncut steel pipe 1 below, and the slag can be prevented from accumulating in the uncut part of the steel pipe 1.

[0063] In actual setting, the angle α is preferably not greater than 45°.

[0064] Furthermore, a conveying mechanism (not shown in the figure) is provided for the steel pipe 1 cut by the laser cutting unit 31 to convey the steel pipe 1 .

[0065] At this time, the conveying mechanism is located on the side of the laser cutting unit 31 away from the support assembly 2 to convey the steel pipe, and the cut part of the steel pipe arrangement can be conveyed to the next process. In addition, the steel pipe arrangement after cutting at the bearing position can also be preferably rotated by the roller 21 to the conveying mechanism and transported to the next process.

[0066] Further preferably, at least one baffle 6 is provided on both sides of the bearing position to block the steel pipe arrangement to prevent the steel pipe 1 from falling from the bearing position. The baffles 6 are preferably symmetrically arranged along both sides of the bearing position. Furthermore, the height of the baffles 6 on both sides of the bearing position is preferably not lower than the top of the steel pipe located on the bearing position.

[0067] The steel pipe laser cutting system of the utility model clamps the rows of steel pipes 1 to be cut sent by the rollers 21 to a fixed length through the clamping mechanism 4, and further drives the laser cutting unit to move along the outer contour of the steel pipe to cross-cut multiple steel pipes, thereby realizing clamping and cutting of multiple steel pipes at one time, which can significantly reduce the waiting time of the machine and greatly improve the production efficiency.

[0068] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
