DETAILED DESCRIPTION

[0026] In the related art, three methods are generally used for online cutting in the pipe manufacturing industry: laser cutting, rotary cutting and saw blade cutting.

[0027] Laser cutting is done using a laser follower cutting machine. Specifically, the laser follower cutting machine has a cutting head. When cutting a workpiece, the cutting head rotates around the workpiece to complete the cutting of the workpiece. However, most laser follower cutting machines in related technologies use a single cutting head, which needs to rotate 360° to complete the cutting of the workpiece. The cutting efficiency is low, and the optical fiber needs to be bent frequently due to the large rotation angle of the cutting head. The optical fiber is difficult to lay out and is easily damaged, and the laser follower cutting machine is easily damaged.

[0028] Rotary cutting is to drive the cutter to rotate and cut the pipe instantly by a motor. However, this cutting method has the problems of short cutter life and poor cut quality, and the equipment is noisy. In addition, saw blade cutting also has the problems of short cutter life and low cutting efficiency.

[0029] In response to the above technical problems, an embodiment of the present application provides a follow-up cutting device, including a mounting base and at least two cutting components, each of which includes a cutting piece, and each cutting piece is suitable for cutting a workpiece to be cut. In this way, compared with the prior art using a single cutting head, the at least two cutting pieces in the present application can jointly achieve the cutting of the workpiece to be cut, thereby maximizing the cutting efficiency; at the same time, the present application helps to reduce the rotation angle of each cutting component, ensure the normal operation of the follow-up cutting device, and extend the service life of the follow-up cutting device; in addition, the follow-up cutting device of the present application is not limited by the shape and thickness of the workpiece to be cut, has a wide range of applications, and no mechanical noise is generated during the cutting process, thereby improving the user experience.

[0030] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] Reference Figure 1 and Figure 2 As shown, the embodiment of the present application provides a follow-up cutting device 100, which may include a mounting base 110 and at least two cutting assemblies 120. Figure 1 , Figure 3 and Figure 4 As shown, the mounting base 110 has a mounting position 200 for mounting a workpiece 300 to be cut (see Figure 4 As shown in FIG. 1 ), at least two cutting assemblies 120 are installed on the mounting base 110 and are located on the peripheral side of the mounting position 200 .

[0032] In the embodiment of the present application, the mounting base 110 serves as a basic structure to provide a mounting base for the cutting assembly 120, which helps to ensure the normal operation of the cutting assembly 120 and ensures stable cutting of the cutting assembly 120 during the cutting process, thereby helping to improve the cutting efficiency of the workpiece 300 to be cut and the quality of the cut. In addition, in the embodiment of the present application, the type, shape, size, etc. of the workpiece 300 to be cut are not limited. Exemplarily, the workpiece 300 to be cut can be in the shape of a plate or a tube. In the present embodiment, the workpiece 300 to be cut is mainly described as a plate-like structure.

[0033] In the embodiment of the present application, there is no limitation on the connection method between the mounting base 110 and the cutting assembly 120. For example, the mounting base 110 and the cutting assembly 120 can be connected by welding, screw connection, clamping connection, sliding connection, etc., which is not limited in the present embodiment. In addition, there is no limitation on the shape, size, etc. of the mounting base 110. It can be set according to actual conditions.

[0034] In the embodiment of the present application, the mounting base 110 has a mounting position 200 for mounting the workpiece 300 to be cut. It should be noted that the "mounting position" is not a fixed position, and it can be changed with the mounting position of the workpiece 300 to be cut. Exemplarily, if the workpiece 300 to be cut is directly mounted on the mounting base 110, then the area where the mounting base 110 contacts the workpiece 300 to be cut is called the mounting position 200; exemplarily, if the workpiece 300 to be cut is mounted on the cutting assembly 120, then the area where the cutting assembly 120 contacts the workpiece 300 to be cut is called the mounting position 200. This is not limited in the present embodiment.

[0035] It should be noted that, refer to Figure 1 , Figure 3 and Figure 4 As shown, at least two cutting assemblies 120 are located on the peripheral side of the installation position 200, so that the two cutting assemblies 120 can cut the workpiece 300 to be cut from different directions of the installation position 200, and the two cutting assemblies 120 cut synchronously or asynchronously, thereby achieving cutting of different positions of the workpiece 300 to be cut, thereby improving the cutting efficiency of the workpiece 300 to be cut.

[0036] In the embodiment of the present application, each cutting assembly 120 may include a cutting member 121, and the cutting member 121 may be movably arranged relative to the mounting position 200. It should be noted that the movably arranged manner may be: for example, the cutting member 121 rotates relative to the mounting position 200; or the cutting member 121 moves horizontally (for example, slides) relative to the mounting position 200, and this embodiment does not limit this. In this way, it is helpful to ensure the movement of the cutting member 121, and then ensure the normal operation of the cutting member 121, so as to achieve the cutting of the workpiece 300 to be cut.

[0037] Among them, each cutting piece 121 is suitable for cutting the workpiece 300 to be cut. In this way, compared with the prior art using a single cutting head, at least two cutting pieces 121 in the present application can jointly realize the cutting of the workpiece 300 to be cut, thereby maximizing the cutting efficiency; at the same time, the present application helps to reduce the rotation angle of each cutting piece 121 to ensure the normal operation of the follow-up cutting device 100.

[0038] It should be noted that in the embodiments of the present application, the type of the follow-up cutting device is not limited. For example, the follow-up cutting device may be a laser follow-up cutting device; or, the follow-up cutting device may be a mechanical follow-up cutting device; or, the follow-up cutting device may also be other devices with cutting functions.

[0039] In this embodiment, the follow-up cutting device 100 is mainly a laser follow-up cutting device for example. In this way, during the cutting process, the cutting efficiency can be improved to the greatest extent; at the same time, the device of the present application helps to reduce the rotation angle of each cutting member 121, so that the optical fiber does not need to be bent frequently, which is beneficial to the layout of the optical fiber, avoids the problem of frequent bending and easy damage of the optical fiber, ensures the normal operation of the follow-up cutting device 100, and extends the service life of the follow-up cutting device 100. In addition, the laser cutting of the present application is non-contact cutting, the incision will not be deformed, the cut surface quality is high, and no mechanical noise is generated during the cutting process.

[0040] In a feasible implementation, in the embodiment of the present application, each cutting member 121 may have a cutting path, and the cutting paths of each cutting member 121 are mutually coupled to form a closed loop surrounding the mounting position 200 .

[0041] It should be noted that the cutting path is the movement path of the laser beam when the cutting component 120 performs a cutting operation. For example, the cutting path can be formed by manual control or by automatic path generation.

[0042] For example, two cutting assemblies 120 are used as an example for description. Figure 5 As shown in the schematic diagram, the first cutting assembly 150 can be moved along Figure 5 The second cutting assembly 160 can be cut along the solid line to form a first cutting path, the starting point of the first cutting path is A1 and the end point is B1. Figure 5 Cutting is performed in the direction of the middle dotted line to form a second cutting path, the starting point of the second cutting path is B2, and the end point is A2, the starting point A1 of the first cutting path and the end point A2 of the second cutting path are connected, the end point B1 of the first cutting path and the starting point B2 of the second cutting path are connected, and a closed loop is formed around the installation position 200.

[0043] It should be noted that the lengths of the first cutting path and the second cutting path are not limited. For example, when the rotation angles of the two cutting components 120 are the same, the lengths of the first cutting path and the second cutting path are the same; or, when the rotation angle of one cutting component 120 is greater than the rotation angle of the other cutting component 120, the length of the first cutting path is greater than the length of the second cutting path; or, when the rotation angle of one cutting component 120 is less than the rotation angle of the other cutting component 120, the length of the first cutting path is less than the length of the second cutting path. This embodiment does not limit this.

[0044] In some embodiments, the two cutting assemblies 120 can cut synchronously. Compared with using a single cutting head, each cutting assembly 120 in the present application does not need to circle the workpiece to complete the cutting of the workpiece, thereby maximizing the cutting efficiency and helping to reduce the rotation angle of each cutting assembly 120, avoiding the problem of frequent bending and easy damage of the laser optical fiber; at the same time, since the laser optical fiber does not need to be bent frequently, this is conducive to the layout of the laser optical fiber, ensuring the normal operation of the follow-up cutting device 100, and extending the service life of the follow-up cutting device 100.

[0045] It should be noted that in the embodiment of the present application, there is no limitation on the number of cutting assemblies 120. For example, the number of cutting assemblies 120 may include two, and the two cutting assemblies 120 are located on opposite sides of the installation position 200; or the number of cutting assemblies 120 may include three, and the three cutting assemblies 120 are located at intervals around the installation position 200; or the number of cutting assemblies 120 may include more, and more cutting assemblies 120 are located around the installation position 200.

[0046] In this embodiment, the following cutting device 100 includes two cutting assemblies 120 as an example for description. Figures 3 to 5 As shown, the cutting assembly 120 may include a first cutting assembly 150 and a second cutting assembly 160, and the first cutting assembly 150 and the second cutting assembly 160 are respectively arranged on opposite sides of the installation position 200; the cutting path of the first cutting assembly 150 and the cutting path of the second cutting assembly 160 are connected end to end to form a closed loop surrounding the installation position 200.

[0047] It should be noted that the setting positions of the first cutting component 150 and the second cutting component 160 include but are not limited to the opposite sides of the installation position 200. As long as the cutting path can be connected end to end to form a closed loop surrounding the installation position 200, it falls within the protection scope of this application.

[0048] In this way, the first cutting component 150 and the second cutting component 160 perform cutting from opposite sides of the installation position 200. Compared with the use of a single cutting head, each cutting component 120 in the present application does not need to circle the workpiece once to complete the cutting of the workpiece, thereby maximizing the cutting efficiency of the workpiece 300 to be cut; at the same time, it helps to shorten the cutting paths of the first cutting component 150 and the second cutting component 160 respectively, thereby helping to reduce the rotation angle of the first cutting component 150 and the second cutting component 160, and avoiding the problem of frequent bending and easy damage of the laser optical fiber.

[0049] In one feasible embodiment, the cutting member 121 may have a first movable path along a first direction and a second movable path along a second direction, the first direction may be a direction approaching or moving away from the mounting position 200, the second direction is a moving direction of the workpiece 300 to be cut, and the first direction and the second direction intersect with each other.

[0050] It should be noted that the active path of the cutting element 121 and the cutting path are not the same path. The cutting path is the movement path of the laser beam when the cutting element 121 performs a cutting operation, and the active path refers to the movement mode of the cutting element 121: for example, the rotational movement or translational movement of the cutting element 121.

[0051] In the present application, refer to Figure 1 , Figure 3 and Figure 4 As shown, the first direction may be a direction close to or away from the mounting position 200. For example, the first direction may be Figure 1 and Figure 3 The direction shown by the y-axis, the second direction can be Figure 1 It can be understood that the direction indicated by the x-axis refers to the horizontal movement direction, that is, in this embodiment, the movement direction of the workpiece 300 to be cut is along the horizontal direction.

[0052] It should be noted that the first direction and the second direction intersect each other. Exemplarily, the first direction and the second direction may intersect each other perpendicularly, or the first direction and the second direction may intersect each other obliquely, which is not limited in this embodiment. This arrangement can ensure that the cutting member 121 moves synchronously with the workpiece 300 to be cut during the movement of the workpiece 300 to be cut, thereby helping to ensure that the cutting assembly 120 follows the uninterrupted cutting of the workpiece 300 to be cut, and realize the follow-up cutting between the cutting assembly 120 and the workpiece 300 to be cut.

[0053] It should be added that the follow-up cutting technology is a key technology of the follow-up cutting device 100, which mainly relies on computers, numerical control systems and other devices to achieve fast and efficient positioning of the cutting piece 121 and the workpiece 300 to be cut. During the processing, the follow-up cutting technology can ensure the tracking accuracy of the follow-up cutting device 100 on the surface of the workpiece 300 to be cut, correctly control the cutting direction and depth, thereby improving the processing accuracy and efficiency.

[0054] In one possible implementation, referring to Figure 6 As shown, the follow-up cutting device 100 may include a first mounting member 170, which is connected to the mounting base 110; the cutting assembly 120 may include a second mounting member 127 and a rotating driving member 123; the second mounting member 127 is connected to the first mounting member 170, and the cutting assembly 120 is connected to the mounting base 110 via the second mounting member 127 and the first mounting member 170.

[0055] In the embodiment of the present application, the shape, material, size, etc. of the first mounting member 170 are not limited. For example, the first mounting member 170 can be a mounting plate. In addition, the connection method between the first mounting member 170 and the mounting base 110 is not limited. For example, the first mounting member 170 and the mounting base 110 can be connected by clamping, threading, welding, bonding, etc., which is not limited in the present embodiment.

[0056] In the embodiment of the present application, there is no limitation on the connection method between the second mounting member 127 and the first mounting member 170, which can be set according to actual conditions. In addition, there is no limitation on the shape, material, size, etc. of the second mounting member 127. For example, the second mounting member 127 can be a mounting plate.

[0057] In the embodiment of the present application, the rotation driving member 123 is movably connected to the second mounting member 127 , the cutting member 121 is rotationally connected to the rotation driving member 123 , and the rotation driving member 123 is used to drive the cutting member 121 to rotate relative to the mounting position 200 .

[0058] It should be noted that the rotation drive member 123 in this embodiment can be a servo motor, specifically, a 400W servo motor. It should be noted that the rotation drive member 123 in this embodiment is mainly used to achieve the displacement of the cutting member 121 in the y-axis / z-axis direction.

[0059] In one possible implementation, referring to Figure 6As shown, the cutting assembly 120 may also include a rotating reduction member 124, a rotating connecting shaft 125 and a rotating crank 126, the input shaft of the rotating reduction member 124 is connected to the rotating driving member 123, the output shaft of the rotating reduction member 124 is connected to the rotating crank 126 through the rotating connecting shaft 125, and the rotating crank 126 is connected to the cutting member 121.

[0060] In the embodiment of the present application, during the installation process, refer to Figure 6 As shown, it can also include a bearing seat 122 and a connecting plate 133, and the rotating connecting shaft 125 is installed in cooperation with the bearing seat 122 to realize the direction rotation of the cutting member 121. The rotating crank 126 is fixedly connected to the connecting plate 133, and the cutting member 121 is fixed on the connecting plate 133.

[0061] It should be noted that the rotating deceleration member 124 in this embodiment can be a speed reducer. The purpose of setting the speed reducer is that when the rotating driving member 123 provides the rotational driving force, if the rotating driving member 123 is directly used to drive, the running speed will be too fast, thereby affecting the normal operation of the rotating driving member 123. At this time, a speed reducer is needed to reduce the speed transmitted by the rotating driving member 123 to the required running speed, thereby helping to reduce the wear of the equipment and thus extend the service life of the mechanical equipment.

[0062] The rotation process of the cutting member 121 in the y-axis / z-axis direction in the embodiment of the present application is described as follows: The rotary drive member 123 is used to provide a rotational driving force, which is connected to the rotary connecting shaft 125 through the rotary speed reducer 124 and the coupling 134. The rotary drive member 123 drives the rotary crank 126 to rotate, thereby driving the cutting member 121 to rotate in the y-axis / z-axis direction. In addition, combined with the cutting path of the equipment and the product, the laser cutting can use a 90° elbow to facilitate the overall layout of the equipment structure, cables and optical fibers.

[0063] For example, the rotation direction of the first cutting assembly 150 and the second cutting assembly 160 can refer to Figure 4 As shown in the rotation direction w, the first cutting assembly 150 and the second cutting assembly 160 rotate relative to each other.

[0064] In one possible implementation, continue to refer to Figure 6 As shown, the cutting assembly 120 may include a translational drive member 128 and a third mounting member 129. The rotational drive member 123 is movably connected to the second mounting member 127 through the third mounting member 129, and the translational drive member 128 is connected to the rotational drive member 123 through the second mounting member 127; the translational drive member 128 is used to drive the rotational drive member 123 to translate relative to the mounting position 200 along the first direction.

[0065] In the embodiment of the present application, there is no limitation on the shape, material, size, etc. of the third mounting member 129. For example, the third mounting member 129 may be a mounting plate.

[0066] It should be noted that the translational drive member 128 in this embodiment can be a servo motor. Specifically, a 400W servo motor can be used. It should be noted that the translational drive member 128 in this embodiment is mainly used to achieve the displacement of the cutting member 121 in the y-axis direction.

[0067] In one possible implementation, referring to Figure 6 As shown, the cutting assembly 120 may include a translation reduction member 130 and a translation connection member 131.

In addition, it should be noted that the structure of the translation connector 131 in the present embodiment includes but is not limited to the translation gear 1311 and the translation rack 1312, and as long as the translation of the cutting member 121 can be achieved, it belongs to the protection scope of the present application.

[0073] In one possible implementation, referring to Figure 6 As shown, a guide assembly 140 may be provided between the second mounting member 127 and the third mounting member 129, and the guide assembly 140 is used to guide the rotation drive member 123 to move along the first direction. In this way, it helps to further ensure that the rotation drive member 123 moves in the first direction, and ensures the stable operation of the cutting member 121.

[0074] Specifically, in the embodiments of the present application, refer to Figure 6 As shown, the guide assembly 140 may include a slider 141 and a slideway 142. One of the slider 141 and the slideway 142 may be disposed on the second mounting member 127, and the other of the slider 141 and the slideway 142 may be disposed on the third mounting member 129. The slideway 142 extends in the first direction. The slider 141 is slidably connected to the slideway 142 along the first direction.

[0075] In the present application, refer to Figure 6 As shown, the description is mainly made by taking the example that the slider 141 is arranged on the second mounting member 127 and the slideway 142 is arranged on the third mounting member 129 .

[0076] In the embodiment of the present application, there is no limitation on the number of sliders 141 and slideways 142. For example, the number of sliders 141 and slideways 142 can be one respectively, and the slider 141 slides in the slideway 142 along the first direction. Alternatively, the number of sliders 141 and slideways 142 can be two respectively, and the two sliders slide in the two slideways 142 along the first direction in a one-to-one correspondence.

In this way, it is helpful to increase the stability during the limiting process, further ensure that the rotating driving member 123 moves in the first direction, and ensure the stable operation of the cutting member 121.

[0078] In one possible implementation, referring to Figure 1 As shown, the mounting base 110 may include a mounting platform 111 and a base driving member 112.

[0081] In the present application, refer to Fig. 9 As shown, the base drive member 112 can use a linear motor as a power source, and the linear motor has the advantages of fast response time, high repeat positioning accuracy and fast running speed. Specifically, in this embodiment, the linear motor can use dual drive to achieve synchronous follow-up.

[0082] It should be noted that, during the actual cutting process, a tachometer can be used to measure the actual speed of the workpiece 300 to be cut. Specifically, its speed is interacted with the follow-up cutting device 100 to achieve matching of the cutting operation speed with the speed of the workpiece 300 to be cut. The linear motor is matched by the speed of the tachometer. When the speed of the linear motor accelerates from static to follow the linear speed, the follow-up cutting device 100 will be triggered to emit light to complete the cutting of the workpiece 300 to be cut. After the cutting is completed, the linear motor is reset, and uninterrupted cutting is repeated over and over again.

[0083] In actual operation, a linear guide rail may be provided on the base drive member 112. This helps ensure that the cutting assembly 120 moves along the linear guide rail, thereby ensuring that the base drive member 112 drives the cutting assembly 120 to move along the second direction.

[0085] In an achievable implementation, the base driving members 112 may include at least two, and at least two cutting assemblies 120 are mounted on the mounting table 111 via the at least two base driving members 112 in a one-to-one correspondence.

In this way, the two cutting assemblies 120 are mounted on the mounting table 111 through the two base driving members 112 in a one-to-one correspondence.

[0087] During the actual working process, the two base driving members 112 simultaneously drive the two cutting assemblies 120 to move horizontally along the second direction. In this way, the consistency of the two cutting assemblies 120 during the translation process can be ensured, thereby ensuring that the two cutting assemblies 120 can cut synchronously, thereby maximizing the cutting efficiency and ensuring the quality of the cut surface.

For example, the base mounting member 113 can use a lead screw with a lead of 20 mm, which helps to meet the high-speed cutting requirements to the greatest extent. The driving power source linear motor of the base mounting member 113 can use a 750w servo motor with a brake, which helps to provide greater torque output and can effectively protect the equipment in the event of a power outage. The base mounting member 113 can be maintained in the corresponding position under the action of the motor's own holding torque to avoid the problem of falling from the base driving member 112.
