Description

Technical Field

[0001] The present application relates to the technical field of pultruded profile cutting, and in particular to a flexible cutting machine. Background Art

[0002] In the pultrusion process of composite materials, the cutting of pultruded profiles is a key step, which directly affects the dimensional accuracy and production efficiency of the product. Traditional pultruded profile cutting machines usually need to be equipped with clamping blocks of specific shapes according to different profile sections, which not only increases the manufacturing cost, but also requires frequent replacement of clamping devices when the profile section is changed, resulting in reduced production efficiency. In addition, existing cutting machines often have difficulty in achieving precise cutting when processing composite materials of different shapes, which limits their application in diversified production needs.

[0003] In practice, the inventors found that the existing pultruded profile cutting machines have technical defects. First, since special clamping blocks are required for profiles of different shapes, this increases the complexity and cost of production preparation. Second, when the cross-section of the profile changes, it is difficult for the existing cutting machine to adapt quickly, resulting in a decrease in production efficiency. In addition, the existing cutting machine may have problems such as clamping slippage and non-vertical cutting surface during the clamping and cutting process, which not only affects the quality of the product, but also increases the difficulty and cost of post-processing.

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0047] Please refer to Figure 1 , Figure 1 A structural diagram of the flexible cutting machine provided in an embodiment of the present application.

[0048] In a specific embodiment, the flexible cutting machine provided in the embodiment of the present application mainly includes a base 1, a profile cutting device 2 and a flexible clamping device 3; the profile cutting device 2 is arranged on the base 1, and the profile cutting device 2 is used to cut the profile; the flexible clamping device 3 is arranged on the base 1, and the flexible clamping device 3 is used to flexibly clamp the profile, so that the profile cutting device 2 can cut the profile.

[0049] Please refer to Figure 2 , Figure 2 A structural diagram of the flexible cutting machine provided in an embodiment of the present application from another perspective.

[0050] The flexible clamping device 3 comprises a clamping driving member 32 and a pair of flexible components 31 distributed on both sides of the profile.

[0051] Please refer to Figure 3 and Figure 4 , Figure 3 A structural diagram of a low-level flexible component provided in an embodiment of the present application, Figure 4 A structural diagram of a high-level flexible component provided in an embodiment of the present application.

[0052] Each flexible component 31 is provided with a plurality of flexible units 311 arranged in an array, the flexible units 311 are used to fit with and support the profile, and the flexible units 311 can be telescopically adjusted according to the shape of the profile; the clamping drive 32 is connected to at least one flexible component 31, and the clamping drive 32 is used to drive a pair of flexible components 31 to clamp the profile.

[0053] Among them, the array arrangement of the flexible units 311 refers to the arrangement of the flexible units 311 on the flexible component 31 according to a certain pattern, and this arrangement can be horizontal, vertical, or a combination of horizontal and vertical directions. Such a design enables the flexible units 311 to better adapt to profiles of different shapes and sizes, and achieve more accurate and extensive support and clamping functions. Through this array arrangement, the flexible cutting machine can more flexibly respond to diverse cutting needs and improve cutting efficiency and accuracy.

[0054] In addition, the expansion and contraction direction of the flexible unit 311 is not limited. When a pair of flexible components 31 clamp the profile up and down, the expansion and contraction direction of the flexible unit 311 is preferably in the up and down direction; when a pair of flexible components 31 clamp the profile left and right, the expansion and contraction direction of the flexible unit 311 is preferably in the left and right direction.

[0055] In traditional pultruded profile cutting machines, since it is necessary to replace special clamping blocks according to different profile cross-sections, this not only increases production costs, but also reduces production efficiency. In addition, when the cross-section of the profile changes, it is difficult for the existing cutting machine to adapt quickly, resulting in unstable cutting quality, such as clamping slippage and non-vertical cutting surface. The existence of these problems directly affects the cutting efficiency and accuracy. In response to these technical problems and defects, the flexible cutting machine provided in this application adopts an innovative design. First, the profile cutting device 2 on the base 1 is used to achieve accurate cutting of the profile. Secondly, the design of the flexible clamping device 3 is the core of this technical solution, which includes a clamping drive 32 and a pair of flexible components 31 distributed on both sides of the profile. A plurality of flexible units 311 are arranged on these flexible components 31, which can be telescopically adjusted according to the shape of the profile to achieve fitting and support with profiles of different shapes. The advantage of this design is that the array arrangement of the flexible unit 311 provides a wide range of adaptability and can adapt to profiles of various shapes and sizes. The telescopic adjustment capability of the flexible unit 311 ensures a close fit and a stable support regardless of the shape of the profile, thereby avoiding the problem of clamping slippage. The function of the clamping drive 32 is to ensure that the flexible component 31 can stably clamp the profile, further improving the stability of the cutting process.

[0056] Combined with the above structure and process description, it can be seen that the flexible cutting machine has at least the following beneficial effects: the flexible cutting machine can adapt to profiles of different shapes, realize the fitting support and shape-adaptive clamping of the profiles, thereby improving the cutting efficiency and accuracy.

[0057] It should be noted that the profile referred to in this application refers in particular to composite pultruded profiles. With regard to the prior art, in the composite pultrusion molding process, there are problems such as the need to equip different conformal clamping blocks when the pultruded profile section is replaced, and the cutting surface is not vertical when the profile clamping slips. The current solution is: for profiles with different cross-sections, when switching production, the corresponding conformal clamping is replaced. For the problem of clamping slipping and uneven cutting ends, the solution is to configure other devices such as handheld cutting devices, and then add a cutting process offline after the profile pultrusion is completed, or to increase the cutting "volume" online. However, this method has the following disadvantages: 1. Different profile sections are equipped with corresponding clamping mechanisms, which will increase the production and manufacturing costs; 2. After the profile pultrusion production is completed, cutting is faced with the problem that the production site needs to have enough space, and cutting is done in a static state after the processing is completed; 3. The method of increasing the volume will lead to waste of composite products produced. Generally speaking, the fiber raw materials, resins, etc. of composite products have high costs.

[0058] Therefore, the present application solves the problem that composite material pultrusion products need to be equipped with conformal clamping devices to adapt to profiles of different shapes by configuring a flexible clamping method.

[0059] The flexible cutting machine is further described below.

[0060] In some embodiments, the number of the flexible clamping devices 3 is a pair, and the pair of flexible clamping devices 3 is located on both sides of the profile cutting device 2 .

[0061] In this embodiment, the flexible clamping devices 3 are designed to be used in pairs, and each pair of flexible clamping devices 3 is located on both sides of the profile cutting device 2, that is, one flexible clamping device 3 is located at the front section of the profile, and the other flexible clamping device 3 is located at the rear section of the profile.

[0062] This layout allows the cutting machine to firmly clamp the profile from both the front and rear positions during the cutting operation, which can ensure that the profile remains stable during the cutting process, reduce vibration and movement, and thus improve the cutting accuracy and efficiency. In addition, the flexible clamping device 3 is arranged on both sides of the profile cutting device 2, which also helps to achieve a more uniform clamping pressure distribution and avoid deformation or damage of the profile due to uneven pressure. This design makes full use of the principle of symmetry to ensure balance and stability during the cutting process.

[0063] In some embodiments, a pair of flexible components 31 are distributed on both sides of the profile along the height direction.

[0064] In this embodiment, the flexible components 31 are designed to be distributed on both sides of the profile along the height direction, that is, one flexible component 31 is located above the profile, equivalent to a high-position flexible component 31, and the other flexible component 31 is located below the profile, equivalent to a low-position flexible component 31.

[0065] This distribution method enables the flexible clamping device 3 to adapt to profiles of different heights and provide more comprehensive support and clamping. By arranging the flexible components 31 in the height direction, it can be ensured that the cutting machine can effectively clamp the profile regardless of how the size of the profile changes, thereby improving the adaptability and flexibility of the cutting machine. In addition, this layout also helps to maintain the stability of the profile during the cutting process, reduce errors caused by improper clamping, and further improve the accuracy and quality of cutting.

[0066] It should be noted that this embodiment does not limit the connection object and driving form of the clamping drive member 32. For example, the clamping drive member 32 can be connected to the high-position flexible component 31 or the low-position flexible component 31, as long as it can drive a pair of flexible components 31 to clamp the profile. For example, the clamping drive member 32 can be an electric, pneumatic or hydraulic driving structure, such as an electric telescopic rod, etc., which should also belong to the description scope of this application.

[0067] In some embodiments, the clamping drive 32 includes a vertically arranged pneumatic piston rod, which is connected to the high-positioned flexible component 31.

[0068] In this embodiment, the clamping drive 32 adopts a vertically arranged pneumatic piston rod. This design allows the clamping force to act directly on the high-position flexible component 31 through the pneumatic piston rod. The application of the pneumatic piston rod provides an efficient and controllable way to adjust and apply the clamping force, ensuring the accuracy and stability of the clamping process. Through the connection with the flexible component 31, the pneumatic piston rod can respond quickly when needed to achieve tight clamping of the profile, while reducing the risk of damage to the profile due to improper clamping. In addition, the use of the pneumatic piston rod also helps to improve the response speed of the entire clamping mechanism and the convenience of operation.

[0069] Please refer to Figure 6 , Figure 6 A control diagram of the clamping drive member provided in an embodiment of the present application.

[0070] In some embodiments, the flexible cutting machine also includes a control system, which is provided with a pressure sensor 6 and a displacement sensor 7 for detecting the pneumatic piston rod. The control system controls the pneumatic piston rod according to the detection data of the pressure sensor 6 and the displacement sensor 7.

[0071] like Figure 6As shown, taking each flexible clamping device 3 as an example, a pair of pneumatic piston pull rods are provided, and a pair of flexible clamping devices 3 are provided with a total of four pneumatic piston pull rods corresponding to Figure 6 There are four cylinders 8 in the invention, each cylinder 8 is located on its own control line, a pressure sensor 6 and a displacement sensor 7 are arranged on the cylinder 8, the cylinder 8 is divided into a first air port communicating with a first branch of the control line and a second air port communicating with a second branch, the four control lines of the four cylinders 8 are connected to a distribution valve 9 in common, a balance valve 10 and a reversing valve 11 are connected behind the distribution valve 9, a muffler 12, a relief valve 13, a pressure gauge 14 and an air filter 15 are arranged behind the reversing valve 11.

[0072] In this embodiment, the pneumatic control principle of the pneumatic piston rod involves using a pressure sensor 6 to detect and adjust the downward pressing pressure to ensure that the clamping force on the profile is appropriate and uniform. At the same time, the displacement sensor 7 is responsible for detecting and controlling the downward pressing height of the pneumatic piston rod to ensure the accuracy of the clamping position. Through this precise pneumatic control, the flexible cutting machine can adapt to profiles of different shapes and sizes, achieving efficient and accurate cutting operations.

[0073] Please continue to refer to Figure 3 and Figure 4 In some cases, the pair of flexible components 31 have the same structure except that they are different in the upper position and the lower position.

[0074] In some embodiments, the flexible component 31 includes a clamping seat 312 having a plurality of mounting positions, in which the flexible unit 311 is mounted.

[0075] In this embodiment, the design feature of the flexible component 31 is that it includes a clamping seat 312, on which a plurality of mounting positions are provided. The purpose of these mounting positions is to install the flexible unit 311. By providing a plurality of such mounting positions on the clamping seat 312, it can be ensured that the flexible unit 311 is assembled on the flexible component 31 according to a predetermined layout. Such a design allows the flexible unit 311 to be properly adjusted and positioned according to the profile contour to achieve effective clamping of profiles of different shapes and sizes. The installation method of the flexible unit 311 provides a flexible and adjustable solution to meet the specific needs of various profiles, and enhances the adaptability and flexibility of the cutting machine to different profiles.

[0076] Please refer to Figure 5 , Figure 5 A structural diagram of a flexible unit provided in an embodiment of the present application.

[0077] In some embodiments, the mounting position includes a hole with an internal thread; the flexible unit 311 includes a connected support rod 3111 and a sleeve 3112, and the support rod 3111 is provided with an external thread that matches the internal thread.

[0078] In this embodiment, the mounting position in the clamping seat 312 of the flexible component 31 is specially designed to include a hole with an internal thread, and such a design allows the flexible unit 311 to be fixed by a threaded connection. The flexible unit 311 is composed of a support rod 3111 and a sleeve 3112 connected to each other, wherein one end of the support rod 3111 is designed with an external thread, which can match and tighten with the hole with an internal thread of the mounting position, thereby achieving stable installation of the flexible unit. In particular, this threaded connection method not only provides convenience for installation, but also allows the position of the flexible unit 311 to be adjusted, thereby achieving telescopic adjustment according to the shape of the profile to adapt to profiles of different sizes and shapes. The connection between the support rod 3111 and the sleeve 3112, combined with the design of the internal threaded hole, provides a high degree of adjustability and adaptability for the entire flexible clamping device 3, ensuring a stable clamping of the profile during the cutting process, thereby improving the accuracy and efficiency of cutting.

[0079] The flexible unit 311 can achieve vertical height adjustment through threaded fitting.

[0080] Optionally, the sleeve 3112 is made of soft material, such as plastic whose stiffness is less than that of the profile, to avoid damaging the profile during clamping.

[0081] Please continue to refer to Figure 5 In some embodiments, the flexible unit 311 further includes a fastening square head 3113 disposed on the support rod 3111 , and the fastening square head 3113 is used to cooperate with a tool to screw the support rod 3111 .

[0082] The tool that cooperates with the tightening square head 3113 to screw the support rod 3111 may be a wrench.

[0083] Please continue to refer to Figure 4 In some embodiments, the flexible unit 311 further includes a locking nut 3114 disposed on the support rod 3111 , the locking nut 3114 and the sleeve 3112 are located on both sides of the clamping seat 312 , and the locking nut 3114 is used to lock the telescopic distance of the flexible unit 311 .

[0084] Continuing with the example of realizing vertical adjustment of the flexible unit 311, when the flexible unit 311 is adjusted up and down to a suitable position, the locking nut 3114 is used to lock it to ensure that the flexible unit 311 on a pair of flexible components 31 fits the profile.

[0085] In some embodiments, the flexible cutting machine further comprises:

[0086] A support platform 4 is movably mounted on the base 1, and a profile cutting device 2 and a flexible clamping device 3 are installed on the support platform 4;

[0087] The first driving mechanism is arranged on the base 1 and is used to drive the support platform 4 to move, and the speed of the movement is synchronized with the speed of the profile moving forward.

[0088] In this embodiment, the design of the flexible cutting machine further includes a support table 4, which is movably mounted on the base 1, which means that the support table 4 can move relative to the base 1. The support table 4 integrates the profile cutting device 2 and the flexible clamping device 3, and such an integrated design makes the entire cutting process more compact and efficient.

[0089] In addition, the flexible cutting machine is also equipped with a first driving mechanism, which is also arranged on the base 1. The main function of the first driving mechanism is to drive the support table 4 to move, ensuring that the movement speed of the support table 4 is synchronized with the speed of the profile. This synchronous movement mechanism is essential to ensure the continuity and stability of the cutting process, which helps to achieve accurate cutting positions and improve production efficiency.

[0090] It should be noted that this embodiment does not limit the driving principle and specific form of the first driving mechanism, which may be an electric, pneumatic or hydraulic driving structure, such as an electric telescopic rod, a forward motor and its transmission mechanism such as gears, racks, etc., which should all fall within the scope of description of this application.

[0091] In some embodiments, the flexible cutting machine further comprises:

[0092] A pair of support assemblies 5 are provided on the base 1 . The pair of support assemblies 5 are located on both sides of the profile cutting device 2 . The height of the support assemblies 5 is adjustable. The support assemblies 5 are used to support the profile.

[0093] In this embodiment, the design of the flexible cutting machine is further extended to include a pair of support assemblies 5. The pair of support assemblies 5 are arranged on the base 1 and are located on both sides of the profile cutting device 2. This layout provides additional support points for the profile and enhances the stability of the entire cutting process.

[0094] The height of the support assembly 5 is adjustable, which allows the operator to adjust it according to the specific size of the profile and the cutting requirements to ensure that the profile is properly supported during the cutting process. The adjustable height design makes the flexible cutting machine more adaptable and can handle profiles of different heights, thereby improving the versatility and flexibility of the cutting machine.

[0095] The support assembly 5 is in the form of a roller, including a roller and columns supported on both sides of the roller, and the roller is adjustable in height along the columns. The main function of the support assembly 5 is to support the profile during the cutting process to prevent the profile from displacement or vibration when subjected to cutting force. In addition, the support assembly 5 can also conform to the feeding of the profile during the processing, thereby satisfying the profile being cut in the flexible cutting machine while the processing is moving forward.

[0096] In some cases, such as Figure 2 As shown, a pair of support components 5 are located at the leftmost end and the rightmost end of the base 1 , and the support platform 4 and the profile cutting device 2 and the flexible clamping device 3 thereon are located between the pair of support components 5 .

[0097] In some embodiments, the profile cutting device 2 comprises:

[0098] Cutting saw blade guard 21;

[0099] The cutting machine moves a linear guide rail 22, which is provided on the cutting saw blade guard 21;

[0100] The cutting saw body 23 is disposed on the cutting saw blade protection cover 21 and can move along the cutting machine moving linear guide rail 22 .

[0101] In this embodiment, the main function of the cutting saw blade guard 21 is to protect the operator and the machine from flying chips or accidental injuries that may be caused by the high-speed rotating saw blade. Figure 1 and Figure 2 As shown, the cutting saw body 23 is located on one side of the cutting saw blade guard 21, and the other side can be protected from flying chips by the cutting saw blade guard 21. The cutting machine motion linear guide rail 22 is arranged on one side outside the cutting saw blade guard 21 to provide a stable motion path for the cutting saw body 23. This design enables the cutting saw body to move smoothly along the guide rail, reducing errors caused by friction or vibration, thereby improving the straightness and accuracy of cutting. The cutting saw body 23 can move along the cutting machine motion linear guide rail 22.

[0102] In addition, the profile cutting device 2 also includes a second driving mechanism, which is used to drive the cutting saw body 23 to move along the cutting machine motion linear guide 22, and then use the cutting action of the cutting saw body 23 to achieve complete cutting of the profile. The second driving mechanism can be an electric, pneumatic or hydraulic driving structure, such as an electric telescopic rod, a forward motor and its transmission mechanism such as a gear, a rack, etc., which should also belong to the description scope of this application.

[0103] In some embodiments, the flexible cutting machine further comprises:

[0104] It should be noted that the structural form of the cutting saw body 23 does not belong to the description scope of this embodiment. For example, the cutting saw body 23 includes a cutting saw motor, a pulley, a cutting saw blade, etc., which can be referred to the prior art and will not be described here one by one.

[0105] Furthermore, dust collecting device connection ports are provided on both sides of the cutting saw blade protective cover 21 .

[0106] Exemplarily, the cutting saw blade is a toothless saw, and the surface of the saw blade is inlaid with diamond grit, which is suitable for cutting composite materials and avoids the saw blade from damaging fibers during cutting.

[0107] In a specific implementation, the flexible cutting machine is controlled synchronously with the pultrusion equipment, and adaptive adjustment is performed when the corresponding profile traction slips and the speed is not synchronized.

[0108] Specifically, the first driving mechanism includes a forward motor that controls the entire support platform 4 to move forward and backward. A speed sensor is also provided to detect whether the current forward speed of the support platform 4 is synchronized with the speed of profile traction. At the same time, it also receives the speed detection and feedback signal of the traction platform of the pultrusion equipment. Through the reception and feedback of the speed signal, the speed of the support platform 4 is adaptively adjusted to ensure that the speed of the traction speed is consistent, and the cross-section of the cut profile is straight, that is, the cut seam is perpendicular to the direction of profile traction, to avoid the profile being cut or the length not meeting the requirements.

[0109] In a specific implementation, the working process of the flexible cutting machine is described as follows.

[0110] According to the outer contour of the profile to be clamped, the flexible unit 311 on the flexible component 31 is adjusted to achieve the fit with the contour surface of the solidified profile and realize flexible support. Specifically, before formal use, the flexible component 31 is adjusted using a contour template to ensure that the flexible unit 311 fits the contour surface of the solidified pultruded profile. Under the action of the clamping drive 32, specifically the pneumatic piston pull rod, the high-position flexible component 31 moves downward to clamp the profile to be cut, and the low-position flexible component 31 cooperates with the high-position flexible component 31 to clamp the profile together. The first driving mechanism at the bottom, specifically the forward motor, drives the entire support platform 4 and the profile cutting device 2 and the flexible clamping device 3 thereon to move in the direction of the profile. The forward speed signal of the forward motor comes from the speed detection of the clamping and traction mechanism of the pultrusion equipment, and the speed is synchronized with the forward speed of the profile. After starting the cutting saw body 23, the cutting saw rotates and cuts the profile.
