Description

Technical Field

[0001] The invention relates to the technical field of stainless steel pipe processing, in particular to an online laser cutting device for stainless steel pipes. Background Art

[0002] The production of seamless stainless steel tubes is a meticulous and continuous process. It begins with the selection and pretreatment of stainless steel sheets to ensure that the materials used are high quality and defect-free. Subsequently, the sheets are precisely cut to the required size and bent to initially form a tubular structure. In the rolling process, the bent sheets are rolled into tube blanks with uniform wall thickness and straightness by precisely controlling the curling force and speed. The welding process follows closely, welding the two ends of the tube blank to form a complete steel tube while ensuring the welding quality to eliminate the influence of the ferrite layer and improve the overall performance of the steel tube.

[0003] After the welding process is completed, the steel pipe is accurately cut to the specified length by the online fixed-length cutting device. This device can move synchronously and clamp and cut the steel pipe when it reaches the preset length, then release and reset to prepare for the cutting of the next steel pipe.

[0004] However, traditional cutting techniques, such as band saws, have long cutting cycles, and sometimes even require the stainless steel tube forming speed to be reduced to match the cutting speed. For example, circular saws can cut at a faster feed rate, but are prone to hitting the stainless steel tube and causing deformation of the stainless steel. In addition, these cutting methods produce more debris, which may interfere with the continuous production process of stainless steel tubes if accumulated on the fixed-length cutting device or production line for a long time. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an online laser cutting device for stainless steel pipes, which can improve the cutting efficiency, avoid damaging the stainless steel pipes, and reduce the interference with the continuous production process of the stainless steel pipes.

[0006] In order to solve the above technical problems, the present invention provides an online laser cutting device for stainless steel pipes, comprising:

[0007] Connecting seat;

[0008] A translation trolley is installed on the connecting seat and can move forward and backward relative to the connecting seat;

[0013] A distance adjusting device is installed on the slide block and is used to adjust the distance between the laser cutting head and the axis of the cutting circular hole;

[0014] And two sets of clamping devices are installed on the translation trolley and are correspondingly arranged in front and rear of the support seat.

[0017] As an improvement of the above-mentioned scheme, the distance adjusting device includes two first connecting rods, an adjustment block radially slidably connected to the swivel frame, and a servo push rod installed on the swivel frame for driving the adjustment block to move. The adjustment block is arranged on the central axis between the two slide grooves, and one end of the two first connecting rods is hinged to the two laser cutting heads one by one and the other end is hinged to the adjustment block.

[0018] As an improvement of the above solution, the first connecting rod is an arc rod which is bent outward away from the axis of the swivel frame and has a diameter larger than the inner diameter of the swivel frame.

[0019] As an improvement of the above solution, the clamping device includes a supporting member for supporting the stainless steel pipe, two clamping jaws arranged opposite to each other on the left and right and used to clamp the stainless steel pipe, and a clamping drive mechanism for driving the two clamping jaws to open and close.

[0020] As an improvement on the above scheme, the supporting member includes a supporting seat which is slidably connected to the translation trolley up and down, a supporting roller which is rotatably connected to the supporting seat and is used to support the stainless steel pipe, and an adjusting screw fixed on the lower side of the supporting seat. The translation trolley is provided with an adjustment through hole for the translation trolley to pass through, and the adjusting screw is threadedly connected to two adjustment nuts which are respectively located at the upper and lower ends of the adjustment through hole and are against the translation trolley.

[0021] As an improvement of the above scheme, the lower end of the clamping jaw is hinged to the translation trolley, and the clamping drive mechanism includes two second connecting rods and a drive cylinder arranged in the middle of the two clamping jaws. One end of the two second connecting rods is hinged to the middle of the two clamping jaws one by one and the other end is hinged to the output end of the drive cylinder.

[0022] As an improvement of the above solution, anti-slip grooves are provided on the inner side of the upper part of the clamping jaw.

In addition, laser cutting technology produces less debris than traditional methods, which helps to reduce interference with the continuous production process of stainless steel pipes and further improves the production efficiency of the stainless steel pipe production line.

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0044] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0045] like Figure 1As shown, an online laser cutting device for stainless steel pipes in an embodiment of the present invention comprises a connecting seat 100, a translation trolley 200, a support seat 300, a slider 400, a rotating device 500, a laser cutting head 600, a distance adjusting device 700 and a clamping device 800. In fact, the connecting seat 100 is used to install the online laser cutting device for stainless steel pipes of the present invention at the output section of the stainless steel pipe production line, so that the online laser cutting device for stainless steel pipes can perform online cutting on the stainless steel pipes continuously transported from front to back at the output section, thereby ensuring the continuity of the production process and the high efficiency of the cutting operation.

[0046] The translation trolley 200 is mounted on the connection base 100 and can move forward and backward relative to the connection base 100. In fact, the translation trolley 200 can be a single-axis translation mechanism or an AGV trolley, etc., which can move forward and backward or change position on the connection base 100 at a set speed, providing a basis for online cutting.

[0047] The support seat 300 is mounted on the translation trolley 200 and is provided with a cutting circular hole 310 for the stainless steel pipe to pass through. In fact, the support seat 300 not only provides a stable installation platform for the slider 400, the rotating device 500, the laser cutting head 600 and the distance adjustment device 700, but the cutting circular hole 310 on the support seat 300 also provides necessary space for the continuous transportation and cutting of the stainless steel pipe, which not only ensures the smooth passage of the stainless steel pipe during the cutting process, but also ensures that it can continuously move from front to back on the production line.

[0048] The slider 400 is slidably connected to the support seat 300, and the rotating device 500 is installed on the support seat 300 and is used to drive the slider 400 to rotate around the axis of the cutting circular hole 310. In fact, the slider 400 can be slidably connected to the annular groove on the support seat 300, or a swivel rotatably connected to the support seat 300, and the rotating device 500 can be one of a motor-coordinated gear transmission assembly, a motor-coordinated belt transmission assembly, a motor-coordinated chain transmission assembly, a motor-coordinated crank connecting rod assembly, etc., which can drive the slider 400 to rotate around the axis of the cutting circular hole 310, providing a basis for driving the laser cutting head 600 to rotate around the axis of the cutting circular hole 310.

[0049] The laser cutting head 600 faces the axis of the cutting circular hole 310 and is used to cut the stainless steel pipe. In fact, compared with the traditional band saw, the laser cutting head 600 has a faster feed speed when cutting the stainless steel pipe, which can reach 10 to 30 meters per minute, while the feed speed of the band saw is usually between 1 and 1.5 meters per minute. Since the laser cutting head 600 feeds and cuts along a circular path, the laser cutting head 600 takes less time to cut the stainless steel pipe of the same outer diameter compared with the linear feed cutting path of the band saw. In addition, the cutting head will not contact the stainless steel pipe during the laser cutting process, thereby avoiding physical damage to the pipe. Laser cutting technology uses a high-power density laser beam to quickly melt, vaporize or ablate the material, and removes the molten material with the help of a high-speed airflow to achieve precise cutting. This method not only has high cutting accuracy, smooth incisions, and a small heat-affected area, but also produces less debris from laser cutting, which helps to reduce interference with the continuous production process of stainless steel pipes.

[0050] The distance adjusting device 700 is installed on the slider 400 and is used to adjust the distance between the laser cutting head 600 and the axis of the cutting circular hole 310. In fact, the distance adjusting device 700 can be one of a servo translation assembly, a servo telescopic rod, etc., which can drive the laser cutting head 600 to move along the radius of the circular hole, thereby adjusting the distance between the laser cutting head 600 and the center of the circular hole, so that the laser cutting head 600 can be accurately placed in the best cutting position, and can adapt to stainless steel pipes of different outer diameters to meet diverse cutting needs. In this way, the distance adjusting device 700 ensures the flexibility and adaptability of the laser cutting process and improves the efficiency and accuracy of the cutting operation.

[0051] Two sets of the clamping devices 800 are installed on the translation trolley 200 and are correspondingly arranged in front and rear of the support base 300. In fact, the clamping device 800 can be one of the clamping claws, and when it is necessary to cut the stainless steel pipe, it clamps the stainless steel pipe in front and rear of the cutting position respectively, providing a more stable environment for cutting stainless steel, ensuring that the pipe remains stable when cutting the stainless steel pipe, thereby improving the cutting accuracy and ensuring the cutting efficiency.

[0052] It should be noted that the stainless steel pipe online laser cutting equipment of the present invention is preferably provided with a tank chain (not shown in the attached drawings) for supporting and protecting the cables required by the translation trolley 200, the laser cutting head 600, the distance adjusting device 700 and the clamping device 800, which are responsible for ventilation, power supply and communication functions. The tank chain not only provides the necessary cable management for these devices, but also reserves enough space to ensure their normal operation. Through such a design, the translation trolley 200, the laser cutting head 600, the distance adjusting device 700 and the clamping device 800 can be seamlessly connected with the control system of the stainless steel pipe production line, thereby improving the automation of the stainless steel pipe online laser cutting equipment and ensuring the smoothness and efficiency of the cutting process.

[0053] The online laser cutting equipment for stainless steel pipes of the present invention cooperates with each other through a connecting seat 100, a translation trolley 200, a support seat 300, a slider 400, a rotating device 500, a laser cutting head 600, a distance adjusting device 700 and a clamping device 800, which can drive the laser cutting head 600 to rotate to achieve online cutting of the stainless steel pipe. Since the feed speed of laser cutting is fast and the cutting head does not contact the pipe during the cutting process, it not only improves the cutting efficiency, but also does not damage the stainless steel pipe and avoids deformation of the stainless steel pipe. In addition, laser cutting technology produces less debris than traditional methods, which helps to reduce interference with the continuous production process of stainless steel pipes and further improves the production efficiency of the stainless steel pipe production line.

[0054] Specifically, Figure 1 and Figures 3 to 5 As shown, the slider 400 is preferably a rotating ring frame that is rotatably connected to the support seat 300 and coaxially arranged with the cutting circular hole 310, and the rotating device 500 is used to drive the rotating ring frame to rotate back and forth. In fact, when the slider 400 rotates relative to the support seat 300, the slider 400 adopts the form of a rotating ring frame, and the inertia is smaller than that of the block-shaped slider 400 around the annular groove, so that the running track of the laser cutting head 600 is more stable and accurate. In addition, the rotating ring frame is more suitable for the rotating device 500 in the form of a motor-coordinated gear transmission assembly, a motor-coordinated belt transmission assembly, or a motor-coordinated chain transmission assembly.

[0055] It is worth mentioning that the rotating ring frame is preferably provided with two slide grooves 410, and the two oppositely arranged laser cutting heads 600 are slidably connected with the two slide grooves 410 along the radial direction of the rotating ring frame in a one-to-one correspondence. In fact, the two slide grooves 410 extend along the radial direction of the rotating ring, and the two slide grooves 410 are evenly distributed around the rotating axis of the rotating ring at 180 degrees. The laser cutting head 600 is provided with a connecting portion that is slidably connected with the slide groove 410 along the radial direction of rotation, so that the laser cutting head 600 can be adjusted along the radial direction of the rotating ring to be suitable for stainless steel pipes with different outer diameters within a certain range.

[0056] It should be noted that the two laser cutting heads 600 only need to rotate 180 degrees around the rotation axis of the rotating ring to complete the cutting of the stainless steel pipe (in order to ensure that the stainless steel pipe is completely cut off, the laser cutting head 600 should be rotated 1-2 degrees more). When cutting the next cutting part of the stainless steel pipe, the rotating device 500 drives the rotating ring frame to reverse 180 degrees, and then repeats the process, which not only improves the cutting efficiency (increased by nearly 50%), but also realizes efficient and reliable continuous cutting operations.

[0057] Furthermore, if Figure 4 As shown, the distance adjustment device 700 preferably includes two first connecting rods 710, an adjustment block 720 radially slidably connected to the rotating ring frame, and a servo push rod 730 installed on the rotating ring frame for driving the adjustment block 720 to move. The adjustment block 720 is arranged on the central axis between the two slide grooves 410, and one end of the two first connecting rods 710 is hinged to the two laser cutting heads 600 in a one-to-one correspondence, and the other end is hinged to the adjustment block 720. In fact, since the adjustment block 720 is arranged on the central axis between the two slide grooves 410, the laser cutting heads 600 in the two slide grooves 410 and the two first connecting rods 710 are symmetrically arranged relative to the central axis between the two slide grooves 410. When the servo push rod 730 drives the adjustment block 720 to move radially along the rotating ring frame, under the action of the two first connecting rods 710, the two laser cutting heads 600 are synchronously approached or moved away, ensuring that the two laser cutting heads 600 can be adjusted at the same time and have the same distance with the rotation axis of the rotating frame, ensuring the cutting effect of the stainless steel pipe. Furthermore, the first connecting rod 710 is preferably an arc rod that bends outward away from the axis of the swivel frame and has a diameter greater than the inner diameter of the swivel frame. Compared with the first connecting rod 710 that extends in a straight line, the setting of the arc rod can prevent the middle part of the first connecting rod 710 from entering the space controlled by the swivel frame, providing a larger space for cutting the stainless steel pipe, thereby improving the flexibility of the cutting operation.

[0058] Specifically, the clamping device 800 preferably includes a supporting member 810 for supporting the stainless steel pipe, two clamping jaws 820 disposed opposite to each other and used to clamp the stainless steel pipe, and a clamping driving mechanism 830 for driving the two clamping jaws 820 to open and close. In fact, the supporting member 810 is used to support the stainless steel pipe transported from front to back, ensuring that the stainless steel pipe is continuously transported from front to back when cutting is not required; when the stainless steel pipe needs to be clamped, the clamping driving mechanism 830 drives the two clamps to move together at the same time to clamp the stainless steel pipe on the supporting member 810, so as to ensure the stability of the stainless steel pipe when cutting.

[0059] More specifically, Figure 6As shown, the supporting member 810 preferably includes a supporting seat 811 which is slidably connected to the translation trolley 200 up and down, a supporting roller 812 which is rotatably connected to the supporting seat 811 and is used to support the stainless steel pipe, and an adjusting screw 813 fixed to the lower side of the supporting seat 811. The translation trolley 200 is provided with an adjusting through hole 210 for the translation trolley 200 to pass through, and the adjusting screw 813 is threadedly connected to two adjusting nuts 814 which are respectively at the upper and lower ends of the adjusting through hole 210 and are against the translation trolley 200. In fact, the lower side of the supporting seat 811 can be connected one-to-one with the two guide holes on the translation trolley 200 through two guide rods to realize the up and down sliding connection between the supporting seat 811 and the translation trolley 200. When the up and down position of the supporting seat 811 needs to be adjusted, loosen the two adjusting nuts 814 to press the translation trolley 200, and then adjust the up and down position of the adjusting screw 813 to adjust the up and down position of the supporting surface of the supporting roller 812 on the supporting seat 811. It can be used for stainless steel pipes of different outer diameters within a certain range, ensuring that the axis of the stainless steel pipe coincides with the rotation axis of the swivel frame during cutting, thereby ensuring the accuracy of the stainless steel pipe cutting.

[0060] More specifically, Figure 7 As shown, the lower end of the clamping jaw 820 is hinged to the translation trolley 200, and the clamping drive mechanism 830 preferably includes two second connecting rods 831 and a driving cylinder 832 arranged in the middle of the two clamping jaws 820. One end of the two second connecting rods 831 is hinged to the middle of the two clamping jaws 820 in a one-to-one correspondence, and the other end is hinged to the output end of the driving cylinder 832. In fact, the driving cylinder 832 can be one of a cylinder, a hydraulic cylinder, and a telescopic rod. The two second connecting rods 831 and the two clamping jaws 820 are symmetrically arranged relative to the driving cylinder 832. When the output end of the driving cylinder 832 is actuated, the two clamping jaws 820 are driven to open or close at the same time, so as to loosen or clamp the stainless steel pipe on the supporting member 810. More specifically, the inner side of the upper part of the clamping jaw 820 is preferably provided with an anti-slip pattern 821, which contacts the stainless steel pipe through the anti-slip pattern 821 to prevent the stainless steel pipe from sliding relative to the clamping jaw 820, so as to ensure that the clamping jaw 820 cooperates with the supporting frame to clamp the stainless steel pipe.

[0061] In addition, if Figure 1 and Figure 2As shown, the stainless steel tube online laser cutting device of the present invention preferably further includes a compensation device 900, the support seat 300 is connected to the translation trolley 200 for sliding forward and backward, and the compensation device 900 includes a translation driving mechanism 910 installed on the translation trolley 200 for driving the translation trolley 200 to move forward and backward, a calibration block 920 installed on the connection seat 100, and a distance sensor 930 installed on the translation trolley 200 for detecting the front and rear distance of the calibration block 920, and the distance sensor 930 is communicatively connected with the translation driving mechanism 910. In fact, the translation driving mechanism 910 can be a servo translation stage, which can drive the support seat 300 to move forward and backward relative to the translation trolley 200 to a set position. Since the translation trolley 200 moves back and forth on the connecting seat 100, it is easy to cause positioning errors relative to the stable output speed of the stainless steel pipe. The positioning error can be measured by cooperating with the distance sensor 930 and the calibration block 920, and the translation drive mechanism 910 can drive the support seat 300 to move a corresponding distance to compensate for the positioning error, improve the fixed-length cutting accuracy of the stainless steel pipe, and ensure the accuracy and reliability of the cutting operation.

[0062] The above are only specific embodiments of the present invention, which show and describe the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
