A method and system for cutting profiles

Abstract

This invention discloses a method and system for cutting profiles. The cutting method includes a first cutting device and a profile moving forward; after the first cutting device reaches a first preset length, a second cutting device moves forward; between the second and first cutting devices, the profile reaches a first cutting length, and the first cutting device cuts the profile and returns; after the second cutting device reaches a second preset length, the first cutting device moves forward; between the first and second cutting devices, the profile reaches a second cutting length, and the second cutting device cuts the profile and returns. Using this cutting method, the first and second cutting devices alternately cut the profile, improving cutting efficiency. Throughout the cutting process, the profile moves at a constant speed without interruption due to cutting operations, ensuring continuous production. The profile cutting length is controlled by controlling the relative distance between the two cutting devices, so even if the profile speed is unstable, it does not affect the cutting length.

Description

Technical Field

[0001] This invention relates to the field of profile processing technology, and more specifically, to a method and system for cutting profiles. Background Technology

[0002] During profile processing, the pultrusion process stretches the profile to a considerable length, necessitating cutting to the required length. In related technologies, profile cutting involves stopping the equipment and then manually cutting. However, since the equipment continuously discharges material during production, stopping the equipment for cutting results in low cutting efficiency and compromises cutting accuracy, making it unsuitable for high-speed continuous profile production lines. Summary of the Invention

[0003] To overcome the problems existing in related technologies, a method and system for cutting profiles are provided.

[0004] In a first aspect, the present invention provides a method for cutting a profile, the method comprising:

[0006] After the first cutting device has traveled a first preset length, the second cutting device is controlled to move forward from the initial position.

[0007] When the relative distance between the second cutting device and the first cutting device reaches the first cutting length, the second cutting device is controlled to switch to torque mode and move forward synchronously with the profile, and the first cutting blade on the first cutting device is controlled to cut in a direction perpendicular to the profile.

[0008] After the first cutting device cuts the profile, it returns to the initial position, and the second cutting device continues to move forward synchronously with the profile.

[0009] After the profile and the second cutting device have traveled a second preset length, the first cutting device is controlled to start moving from the initial position;

[0010] When the relative distance between the first cutting device and the second cutting device reaches the second cutting length of the profile, the first cutting device is controlled to switch to torque mode and move forward synchronously with the profile, and the second cutting blade on the second cutting device is controlled to cut in a direction perpendicular to the running direction of the profile.

[0011] After the second cutting device cuts the profile, it returns to the initial position, and the first cutting device continues to move forward synchronously with the profile.

[0012] In some embodiments, controlling the first cutting device to move forward synchronously with the profile from an initial position includes:

[0014] The step of controlling the first cutting device to return to the initial position after cutting the profile includes:

[0015] After the first cutting device releases the profile, it returns to the initial position.

[0016] In some embodiments, when the relative distance between the second cutting device and the first cutting device reaches the first cutting length, controlling the first cutting device to switch to torque mode and move forward synchronously with the profile, and controlling the first cutting blade on the first cutting device to cut along a direction perpendicular to the profile's movement, includes:

[0017] When the relative distance between the second cutting device and the first cutting device reaches the first cutting length, the second cutting device is controlled to switch to torque mode, and clamps the profile and moves forward synchronously with the profile;

[0018] The first cutting device is controlled to hold the profile, and the first cutting blade on the first cutting device is controlled to cut in a direction perpendicular to the running direction of the profile.

[0019] In some embodiments, controlling the second cutting device to continue moving forward synchronously with the profile includes:

[0020] The second cutting device is controlled to clamp the profile, and the second cutting device is controlled to move forward at the first traveling speed;

[0021] The step of controlling the second cutting device to return to the initial position after cutting the profile includes:

[0022] After the second cutting device releases the profile, it returns to the initial position.

[0023] In some embodiments, after the first cutting device has traveled a first preset length, controlling the second cutting device to move forward from the initial position includes:

[0024] After the first cutting device has traveled a first preset length, the second cutting device is controlled to move forward from the initial position at a second traveling speed, the second traveling speed being determined by the first preset length and the first cutting length.

[0025] In some embodiments, the method for cutting the profile further includes:

[0026] The relative distance between the second cutting device and the first cutting device is determined based on the first traveling speed, the second traveling speed, the first traveling time of the first cutting device, and the second traveling time of the second cutting device.

[0027] Wherein, the first travel time is the travel time of the first cutting device starting from the moment the second cutting device begins to move forward from the initial position, and the second travel time is the travel time of the second cutting device starting from the moment it begins to move forward from the initial position.

[0028] In some embodiments, controlling the first cutting device to start moving from the initial position after the profile and the second cutting device have traveled a second preset length includes:

[0029] After the profile and the second cutting device have traveled a second preset length, the first cutting device is controlled to move forward from the initial position at a third traveling speed, which is determined by the second preset length and the second cutting length.

[0030] In some embodiments, the method for cutting the profile further includes:

[0031] The relative distance between the first cutting device and the second cutting device is determined based on the first traveling speed, the third traveling speed, the third traveling time of the second cutting device, and the fourth traveling time of the first cutting device.

[0032] Wherein, the third travel time is the travel time of the second cutting device from the moment the first cutting device starts moving forward from the initial position, and the fourth travel time is the travel time of the first cutting device from the moment it starts moving forward from the initial position.

[0033] In some embodiments, the first cutting length is equal to the second cutting length.

[0034] A second aspect of the present invention provides a profile cutting system applicable to the cutting method described in any one of the first aspects, comprising:

[0035] An operation adjustment unit is used to adjust the traveling speed and direction of the first cutting device and the second cutting device;

[0036] A cutting control unit, which controls the first cutting blade and the second cutting blade to cut the profile;

[0037] A clamping adjustment unit is used to clamp the profile when the profile moves forward synchronously with the first cutting device or the second cutting device;

[0038] The control unit is used to control the operation of the running adjustment unit, the cutting control unit and the clamping adjustment unit respectively.

[0039] The advantages of the profile cutting method and system described in this invention are as follows:

[0040] In the profile cutting method provided by the first aspect of the present invention, a first cutting device and a second cutting device alternately cut the profile. Since the two cutting devices work alternately, when one cutting device is cutting, the other cutting device can prepare for the next cut, thereby improving the overall cutting efficiency. At the same time, by controlling the travel distance and cutting timing of the first and second cutting devices, it can be ensured that the first cutting length and the second cutting length of the profile are equal, or the first cutting length and the second cutting length of the profile can be different according to actual needs. Two different lengths of profile can be obtained in one cutting process to meet different production needs. The operation is flexible, production efficiency is improved, the number of cutting equipment is reduced, and thus production costs are reduced. Throughout the cutting process, the profile always travels at a constant speed and will not be interrupted by the cutting operation, thereby ensuring the continuity of production and improving production efficiency. Moreover, the profile cutting length is controlled by controlling the relative distance between the two cutting devices, so even if the profile travel speed is unstable, it will not affect the cutting length.

[0041] Since the profile cutting system provided in the second aspect of the present invention includes the profile cutting method described in the first aspect, the profile cutting system also has the advantages of the profile cutting method of the first aspect.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0052] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0053] During the profile processing, the pultrusion process stretches the profile to a longer length, so the profile needs to be cut to the required length.

[0054] In related technologies, production lines for high-speed continuous forming profiles often only have one reciprocating cutting device equipped with a cutting tool. When the cutting device cuts the profile and returns to the origin, the return process of the cutting device takes up cutting time. Due to the short cutting time, it is not suitable for production lines for high-speed forming materials. Alternatively, manual cutting of the profile can be used, with the equipment stopped first and then manual cutting performed. However, since the equipment outlet is constantly discharging material during the profile production process, stopping the equipment for cutting will result in low cutting efficiency and the cutting accuracy cannot be guaranteed, which is also not suitable for production lines for high-speed continuous forming profiles.

[0055] The following is combined Figures 1 to 6 The embodiments of the present invention will be further described below.

[0056] To address the aforementioned technical problems of low cutting efficiency, inability to guarantee cutting accuracy, and unsuitability for production lines of high-speed continuous forming profiles, such as... Figures 1 to 5 As shown, an exemplary embodiment of the present invention provides a method for cutting profiles. It should be noted that this cutting method is applicable to cutting devices that cut profile 1 according to actual needs to meet different requirements in the production process. In this embodiment, the material of profile 1 is not specifically limited. For example, in the construction industry, profile 1 can be materials such as reinforcing bars or steel pipes to meet the requirements of building structures. In other industries, profile 1 can also be materials such as metal or plastic to meet the design and manufacturing requirements of products.

[0057] like Figure 1 and Figure 2 As shown, the methods for cutting profiles include:

[0058] Step S10: Control the profile to move forward at a constant first traveling speed, control the first cutting device to move forward synchronously with the profile from the initial position, and repeatedly execute the following cutting process.

[0059] In other words, referencing Figure 2 The left side of the profile 1 is the initial position. When the cutting of the profile 1 begins using this method, the first cutting device 2 can adopt torque mode and move forward synchronously with the profile 1 from the initial position at a constant first traveling speed.

[0060] Step S20: After the first cutting device has traveled a first preset length, control the second cutting device to move forward from the initial position.

[0061] It should be noted that, referring to Figure 2 The initial position of the first cutting device 2 is the same as the initial position of the second cutting device 3, with the left side of the profile 1 as the initial position. The first cutting device 2 and the second cutting device 3 can be located on the same side of the profile 1, or... Figure 2As shown, the two cutting devices are respectively set on both sides of the profile 1. After the first cutting device 2 has traveled the first preset length L1, the second cutting device 3 can start to travel in the position mode.

[0062] Step S30: When the relative distance between the second cutting device and the first cutting device reaches the first cutting length, control the second cutting device to switch to torque mode and move forward synchronously with the profile, and control the first cutting blade on the first cutting device to cut in a direction perpendicular to the profile.

[0063] Among them, reference Figure 2 and Figure 3 The speed at which the second cutting device 3 begins to move forward from its initial position can be the same as or different from the first moving speed of the profile 1. For example, when the first cutting length L2 is the same as the first preset length L1, the speed at which the second cutting device 3 begins to move forward from its initial position needs to be the same as the first moving speed of the profile 1; when the first cutting length L2 is greater than the first preset length L1, the speed at which the second cutting device 3 begins to move forward from its initial position needs to be less than the first moving speed of the profile 1; when the first cutting length L2 is less than the first preset length L1, the speed at which the second cutting device 3 begins to move forward from its initial position needs to be greater than the first moving speed of the profile 1.

[0064] In step S40, the first cutting device is controlled to cut the profile and return to the initial position, and the second cutting device is controlled to continue to move forward synchronously with the profile.

[0065] Understandably, referring to Figure 3 and Figure 4 When the relative distance between the second cutting device 3 and the first cutting device 2 reaches the first cutting length L2, the traveling speed of the second cutting device 3 immediately becomes consistent with the traveling speed of the profile 1, that is, it moves forward synchronously with the profile 1 at a constant first traveling speed. At this time, the first cutting blade on the first cutting device 2 cuts the profile 1. After the cutting is completed, the first cutting device 2 changes its running direction and can return to the initial position in position mode.

[0066] Step S50: After the profile and the second cutting device have traveled a second preset length, control the first cutting device to start moving from the initial position.

[0067] Among them, reference Figure 4 After the profile and the second cutting device have traveled the second preset length L3, the first cutting device can be controlled to start moving from the initial position in a position mode. The second preset length L3 is the same as the first preset length L1.

[0068] Step S60: When the relative distance between the first cutting device and the second cutting device reaches the second cutting length of the profile, the first cutting device is controlled to switch to torque mode and move forward synchronously with the profile, and the second cutting blade on the second cutting device is controlled to cut in a direction perpendicular to the profile.

[0069] The second cutting length L4 and the first cutting length L2 can be the same or different.

[0070] In step S70, the second cutting device is controlled to cut the profile and return to the initial position, and the first cutting device is controlled to continue to move forward synchronously with the profile.

[0071] Understandably, referring to Figure 5 When the relative distance between the first cutting device 2 and the second cutting device 3 reaches the second cutting length L4, the traveling speed of the first cutting device 2 immediately becomes consistent with the traveling speed of the profile 1, that is, it moves forward synchronously with the profile 1 at a constant first traveling speed. At this time, the second cutting blade on the second cutting device 3 cuts the profile 1. After the cutting is completed, the second cutting device 3 changes its running direction and returns to the initial position.

[0072] It should be noted that in torque mode, the servo controller controls the load torque of the motor by controlling the torque or current output by the motor, so as to meet the precise control of the motor load.

[0073] In position mode, the servo controller controls the movement of the motor by using the difference (error) between the preset target position and the actual position, so that the cutting device moves to the preset position. In this embodiment, the first cutting device 2 and the second cutting device 3 alternately cut the profile 1. Since the two cutting devices work alternately, when one cutting device is cutting, the other cutting device can prepare for the next cut, thereby improving the overall cutting efficiency. At the same time, by controlling the relative distance between the first cutting device 2 and the second cutting device 3 and the cutting timing, it can be ensured that the first cutting length L2 and the second cutting length L4 of the profile 1 are equal. Alternatively, the first cutting length L2 and the second cutting length L4 of the profile 1 can be different according to actual needs. Two different lengths of profile 1 can be obtained in one cutting process to meet different production needs. The operation is flexible, production efficiency is improved, the number of cutting equipment is reduced, and thus production costs are reduced. Throughout the cutting process, the profile 1 always moves at a constant speed and will not be interrupted by the cutting operation, thereby ensuring the continuity of production and improving production efficiency. Furthermore, the cutting length of the profile 1 is controlled by controlling the relative distance between the two cutting devices, so even if the traveling speed of the profile 1 is unstable, it will not affect the cutting length.

[0074] It should be noted that the first cutting device 2 and the second cutting device 3 can each use a servo motor with its own encoder to control the movement of each step, or they can use an encoder or grating ruler connected to a cylinder or torque motor to control the movement of the first cutting device 2 and the second cutting device 3 each time.

[0075] In an exemplary embodiment, controlling the first cutting device to move forward synchronously with the profile from an initial position includes: controlling the first cutting device to clamp the profile, and controlling the first cutting device to move forward at a first traveling speed.

[0076] The first cutting device 2 includes a first cutting blade and a first clamping part, as shown in the figure. Figure 2 When the first cutting device 2 moves forward synchronously with the profile 1 from its initial position, the first clamping part clamps the profile 1 and moves it forward. The first clamping part can not only apply a certain traction force to the profile 1 to ensure that the forward speed of the first cutting device 2 and the profile 1 is consistent, but also ensure that the position and angle of the profile 1 remain stable during the processing and transportation of the profile 1, preventing the profile 1 from sliding and shaking during the process, thereby reducing the time for adjustment and correction, improving production efficiency, and thus improving the cutting accuracy.

[0077] After the first cutting device cuts the profile, it returns to its initial position, including:

[0078] After the first cutting device releases the profile, it returns to its initial position. This is understandable, referring to... Figure 2 During the stage when the first cutting device 2 moves forward from its initial position at a first traveling speed, the first clamping part continuously clamps the profile 1, as shown in the reference. Figure 3 When the relative distance between the second cutting device 3 and the first cutting device 2 reaches the first cutting length L2, the first cutting blade cuts the profile 1. During this process, the first clamping part clamps the profile 1 to ensure the stability of the profile 1 during the cutting process and prevents the profile 1 from moving or vibrating during the cutting process, thereby improving the cutting accuracy, stability and flatness of the cutting surface.

[0079] After the first cutting blade completes its cut, the first clamping part releases the profile 1, as shown in the reference. Figure 4The first cutting device 2 returns to the initial position. The time when the first cutting device 2 returns to the initial position needs to be consistent with the time when the second cutting device 3 travels to the second preset length L3, or before the second cutting device 3 travels to the second preset length L3. For example, when the first cutting device 2 returns to its initial position at the same time as the second cutting device 3 travels to the second preset length L3, the first cutting device 2 arrives at its initial position and immediately begins its journey. This ensures the synchronization of the entire cutting process, effectively utilizes resources and time, and saves cutting time, thereby improving overall cutting efficiency. When the time it takes for the first cutting device 2 to return to its initial position is less than the time it takes for the second cutting device 3 to travel to the second preset length L3, the first cutting device 2 arrives at its initial position and stops waiting until the second cutting device 3 travels to the second preset length L3. Then, the first cutting device 2 begins its next round of travel from its initial position. With this design, the first cutting device 2 and the second cutting device 3 work alternately, and each cutting device has time for cooling and maintenance, thereby extending the service life of the first cutting device 2 and the second cutting device 3, thus improving cutting efficiency and reducing production costs.

[0080] In an exemplary embodiment, when the relative distance between the second cutting device and the first cutting device reaches the first cutting length, the first cutting device is controlled to switch to torque mode and move forward synchronously with the profile. The first cutting blade on the first cutting device is then controlled to cut along a direction perpendicular to the profile's movement, including:

[0081] When the relative distance between the second cutting device and the first cutting device reaches the first cutting length, the second cutting device is controlled to switch to torque mode and clamp the profile and move forward synchronously with the profile; the first cutting device is controlled to keep clamping the profile and the first cutting blade on the first cutting device is controlled to cut in a direction perpendicular to the profile.

[0082] The second cutting device 3 includes a second cutting blade and a second clamping part. It is understood that, referring to... Figure 3 When the relative distance between the second cutting device 3 and the first cutting device 2 reaches the first cutting length L2, the second cutting device 3 switches to torque mode, ensuring that the travel speed of the second cutting device 3 is consistent with the travel speed of the profile 1. The moment when the second clamping part clamps the profile 1 can be either when the relative distance between the second cutting device 3 and the first cutting device 2 reaches the first cutting length L2, or it can be during the time period between when the relative distance between the second cutting device 3 and the first cutting device 2 reaches the first cutting length L2 and before the first clamping part releases the profile 1.

[0083] The first clamping part on the first cutting device 2 continuously clamps the profile 1 and moves forward synchronously at the first traveling speed. When the relative distance between the second cutting device 3 and the first cutting device 2 reaches the first cutting length L2, the first clamping part on the first cutting device 2 continues to clamp the profile 1 and cuts it with the first cutting blade in a direction perpendicular to the travel of the profile 1. Figure 4 After the first cutting blade completes the cutting, the first clamping part releases the profile 1, and the first cutting device 2 returns to the initial position. During this process, the first clamping part clamps the profile 1 to ensure the stability of the profile 1 during the cutting process and prevents the profile 1 from moving or vibrating during the cutting process, thereby improving the cutting accuracy, stability and flatness of the cutting surface.

[0084] In an exemplary embodiment, controlling the second cutting device to continue moving forward synchronously with the profile includes: controlling the second cutting device to clamp the profile and controlling the second cutting device to move forward at a first traveling speed.

[0085] The second cutting device 3 includes a second cutting blade and a second clamping part, as shown in the reference. Figure 3 When the relative distance between the second cutting device 3 and the first cutting device 2 reaches the first cutting length L2, the second clamping part of the second cutting device 3 clamps the profile 1 and moves it forward. The second clamping part can not only apply a certain traction force to the profile 1 to ensure that the forward speed of the second cutting device 3 and the profile 1 is consistent, but also ensure that the position and angle of the profile 1 remain stable during the processing and transportation of the profile 1, preventing the profile 1 from sliding and shaking during the process, thereby reducing the adjustment and correction time, improving production efficiency, and thus improving the cutting accuracy.

[0086] After the second cutting device cuts the profile, it returns to the initial position, including:

[0087] After the second cutting device releases the profile, it returns to its initial position. It is understood that, referring to... Figure 3 When the relative distance between the second cutting device 3 and the first cutting device 2 reaches the first cutting length L2, the second clamping part of the second cutting device 3 begins to clamp the profile 1 and move it forward, referring to... Figure 5 The second cutting blade cuts the profile 1 until the relative distance between the first cutting device 2 and the second cutting device 3 reaches the second cutting length L4. During this process, the second clamping part keeps clamping the profile 1 to ensure the stability of the profile 1 during the cutting process and prevent the profile 1 from moving or vibrating during the cutting process, thereby improving the cutting accuracy, stability and flatness of the cutting surface.

[0088] Reference Figure 5When the second cutting blade finishes cutting, the second clamping part releases the profile 1, and the second cutting device 3 returns to the initial position. The time when the second cutting device 3 returns to the initial position needs to be consistent with the time when the first cutting device 2 travels to the first preset length L1, or before the first cutting device 2 travels to the first preset length L1. For example, when the second cutting device 3 returns to its initial position at the same time as the first cutting device 2 travels to the first preset length L1, the second cutting device 3 reaches its initial position and immediately begins to move from there. This ensures the synchronization of the entire cutting process, effectively utilizes resources and time, and saves cutting time, thereby improving overall cutting efficiency. When the time it takes for the second cutting device 3 to return to its initial position is less than the time it takes for the first cutting device 2 to travel to the first preset length L1, the second cutting device 3 stops and waits until it reaches the first preset length L1. Then, the second cutting device 3 begins the next round of movement from its initial position. With this design, the first cutting device 2 and the second cutting device 3 work alternately, and each cutting device has time for cooling and maintenance, thereby extending the service life of the first cutting device 2 and the second cutting device 3, thus improving cutting efficiency and reducing production costs.

[0089] In an exemplary embodiment, after the first cutting device has traveled a first preset length, controlling the second cutting device to move forward from its initial position includes:

[0090] After the first cutting device has traveled a first preset length, the second cutting device is controlled to move forward from the initial position at a second traveling speed, which is determined by the first preset length and the first cutting length.

[0091] Understandably, referring to Figure 2 and Figure 3The second traveling speed of the second cutting device 3 can be the same as or different from the first traveling speed of the profile 1. For example, when the first cutting length L2 is the same as the first preset length L1, the second traveling speed of the second cutting device 3 starting from the initial position needs to be the same as the first traveling speed of the profile 1 to ensure that the relative distance between the second cutting device 3 and the first cutting device 2 remains unchanged; when the first cutting length L2 is greater than the first preset length L1, the second traveling speed of the second cutting device 3 starting from the initial position needs to be less than the first traveling speed of the profile 1; when the first cutting length L2 is less than the first preset length L1, the second traveling speed of the second cutting device 3 starting from the initial position needs to be greater than the first traveling speed of the profile 1. This design allows the second traveling speed of the second cutting device 3 to be determined based on the first preset length L1 and the first cutting length L2, providing greater flexibility. This means that the traveling speed of the second cutting device 3 can be adjusted according to different production needs and conditions, thereby adapting to different cutting requirements and production processes, optimizing the entire cutting process, and improving production efficiency.

[0092] In one exemplary embodiment, the profile cutting method further includes:

[0093] The relative distance between the second cutting device and the first cutting device is determined based on the first traveling speed, the second traveling speed, the first traveling time of the first cutting device, and the second traveling time of the second cutting device.

[0094] Wherein, the first travel time is the travel time of the first cutting device starting from the moment the second cutting device begins to move forward from the initial position, and the second travel time is the travel time of the second cutting device starting from the moment it begins to move forward from the initial position.

[0095] Yes, that's understandable, refer to Figure 2 and Figure 3The relative distance between the second cutting device 3 and the first cutting device 2 is the actual length required for the profile 1. The first travel time and the second travel time are equal, both being the travel time of the second cutting device 3 from the moment it starts moving forward from its initial position. During operation, the length traveled by the first cutting device 2 within this time period can be calculated using the first travel speed and the first travel time. Then, this length is added to the first preset length L1 to obtain the current position of the first cutting device 2. The travel speed of the second cutting device 3 is then adjusted based on the difference between the current position of the first cutting device 2 and the actual length required for the profile 1, and the second travel time. This design allows the second travel speed of the second cutting device 3 to be determined based on the first travel speed of the profile 1 and the first cutting length L2, providing greater flexibility. This means that the travel speed of the second cutting device 3 can be adjusted according to different production needs and conditions, thereby adapting to different cutting requirements and production processes, optimizing the entire cutting process, and improving production efficiency.

[0096] In an exemplary embodiment, after the profile and the second cutting device have traveled a second preset length, controlling the first cutting device to start moving from the initial position includes:

[0097] After the profile and the second cutting device have traveled a second preset length, the first cutting device is controlled to move forward from the initial position at a third traveling speed, which is determined by the second preset length and the second cutting length.

[0098] Understandably, referring to Figure 4 and Figure 5After the profile 1 and the second cutting device 3 have traveled a second preset length L3, the first cutting device 2 begins to move forward from its initial position at a third traveling speed. The third traveling speed of the first cutting device 2 can be the same as or different from the first traveling speed of the profile 1. For example, when the second cutting length L4 is the same as the second preset length L3, the third traveling speed of the first cutting device 2 from its initial position needs to be the same as the first traveling speed of the profile 1 to ensure that the relative distance between the first cutting device 2 and the second cutting device 3 remains constant at the second cutting length L4. When the second cutting length L4 is greater than the second preset length L3, the third traveling speed of the first cutting device 2 from its initial position needs to be less than the first traveling speed of the profile 1. When the second cutting length L4 is less than the first preset length L1, the third traveling speed of the first cutting device 2 from its initial position needs to be greater than the first traveling speed of the profile 1. This design allows the third travel speed of the first cutting device 2 to be determined based on the second preset length L3 and the second cutting length L4, providing greater flexibility. This means that the travel speed of the first cutting device 2 can be adjusted according to different production needs and conditions, thereby adapting to different cutting requirements and production processes, optimizing the entire cutting process, and improving production efficiency.

[0099] When the relative distance between the first cutting device 2 and the second cutting device 3 reaches the second cutting length L4, the first cutting device 2 is controlled to switch to torque mode and move forward synchronously with the profile 1 while clamping it. Then, the second cutting blade on the second cutting device 3 is controlled to cut in a direction perpendicular to the profile's movement. In an exemplary embodiment, the profile cutting method further includes:

[0100] The relative distance between the first cutting device and the second cutting device is determined based on the first traveling speed, the third traveling speed, the third traveling time of the second cutting device, and the fourth traveling time of the first cutting device.

[0101] The third travel time is the travel time of the second cutting device from the moment the first cutting device starts moving forward from its initial position, and the fourth travel time is the travel time of the first cutting device from the moment it starts moving forward from its initial position.

[0102] Yes, that's understandable, refer to Figure 4 and Figure 5The relative distance between the first cutting device 2 and the second cutting device 3 is the actual length required for the profile 1. The third and fourth travel times are equal, both being the travel time of the first cutting device 2 from its initial position. During operation, the length traveled by the second cutting device 3 within this time period can be calculated using the first travel speed and the third travel time. This length is then added to the second preset length L3 to obtain the current position of the second cutting device 3. The travel speed of the first cutting device 2 is then adjusted based on the difference between the current position of the second cutting device 3 and the actual length required for the profile 1, along with the fourth travel time; this is the third travel speed. This design allows the third travel speed of the first cutting device 2 to be determined based on the first travel speed of the profile 1 and the second cutting length L4, providing greater flexibility. This means that the travel speed of the second cutting device 3 can be adjusted according to different production needs and conditions, thereby adapting to different cutting requirements and production processes, optimizing the entire cutting process, and improving production efficiency.

[0103] In an exemplary embodiment, the first cutting length L2 is equal to the second cutting length L4. The first cutting device 2 and the second cutting device 3 alternately cut the profile 1, and the first cutting length L2 is equal to the second cutting length L4, thereby improving the overall cutting efficiency, meeting production needs, increasing production efficiency, reducing the number of cutting equipment, and thus reducing production costs. Throughout the cutting process, the profile 1 always moves at a constant speed and will not be interrupted by the cutting operation, thereby ensuring the continuity of production and improving production efficiency.

[0104] An exemplary embodiment of the present invention also provides a cutting system for profile 1, applicable to the method of any of the above embodiments, referring to... Figures 2 to 6 It includes a running adjustment unit, a cutting control unit, a clamping adjustment unit, and a control unit. The running adjustment unit adjusts the speed and direction of travel of the first cutting device 2 and the second cutting device 3. The cutting control unit controls the first and second cutting blades to cut the profile 1. The clamping adjustment unit clamps the profile 1 when it moves forward synchronously with the first cutting device 2 or the second cutting device 3. The control unit controls the operation of the profile 1, the running adjustment unit, the cutting control unit, and the clamping adjustment unit respectively.

[0105] For example, at the beginning, refer to Figure 2 and Figure 6The control unit controls the profile 1 to move forward at a constant first traveling speed, and controls the first cutting device 2 to move forward synchronously with the profile 1 from its initial position. Then, in one of the cyclical cutting processes, the control unit transmits control signals to the clamping adjustment unit and the running adjustment unit, causing the clamping adjustment unit to control the first cutting device 2 to clamp the profile 1, and the running adjustment unit to control the first cutting device 2 to move forward. (Refer to...) Figure 2 and Figure 6 After the first cutting device 2 has traveled a first preset length L1, the controller calculates the forward speed signal of the second cutting device 3 from its initial position based on the first preset length L1 and the first cutting length L2. The controller transmits this signal to the operation adjustment unit, which adjusts the forward movement of the second cutting device 3 from its initial position. Figure 3 and Figure 6 When the relative distance between the second cutting device 3 and the first cutting device 2 reaches the first cutting length L2, the controller transmits a signal to the cutting control unit. The cutting control unit controls the first cutting blade on the first cutting device 2 to cut along a direction perpendicular to the profile 1. Simultaneously, the clamping adjustment unit controls the second cutting device 3 to clamp the profile 1. (Refer to...) Figure 4 and Figure 6 After the first cutting device 2 cuts the profile 1, the clamping adjustment unit controls the first cutting device 2 to release the profile 1, and adjusts the first cutting device 2 to return to the initial position through the operation adjustment unit. At the same time, the operation adjustment unit controls the second cutting device 3 to continue to move forward synchronously with the profile 1.

[0106] Reference Figure 4 and Figure 6 When profile 1 and the second cutting device 3 have traveled the second preset length L3, the operation adjustment unit controls the first cutting device 2 to start moving from the initial position. The operating speed of the first cutting device 2 from the initial position is determined by the controller based on the second preset length L3 and the second cutting length L4. The controller transmits this signal to the operation adjustment unit, which adjusts the first cutting device 2 to move forward at this speed from the initial position. Figure 5 and Figure 6When the relative distance between the first cutting device 2 and the second cutting device 3 reaches the second cutting length L4, the controller transmits a signal to the cutting control unit. The cutting control unit controls the second cutting blade on the second cutting device 3 to cut along a direction perpendicular to the profile 1. At the same time, the clamping adjustment unit controls the first cutting device 2 to clamp the profile 1. After the second cutting device 3 cuts the profile 1, the clamping adjustment unit controls the second cutting device 3 to release the profile 1, and the operation adjustment unit adjusts the second cutting device 3 to return to the initial position. At the same time, the operation adjustment unit controls the first cutting device 2 and the profile 1 to continue moving forward synchronously.
