Description

TECHNICAL FIELD

[0001] The present application relates to the field of profile processing, in particular to a wood-like profile corner position sawing and milling processing device and method. BACKGROUND

[0002] The wood-like profile corner position is usually processed by a wood-like (HFL) right-angle welding process, which can realize right-angle welding with wood-like effect, so that the plastic door and window can present the texture and grain of wood on the appearance, improve the overall appearance of the door and window, and make the door and window more coordinated and unified with the home environment. In the specific operation, the plastic wood-like profile is cut into the required length and angle by using a cutting device to prepare for right-angle welding. The cleaned profile is placed on the workbench of the welding device, and the profile is accurately positioned and fixed by the positioning device and the clamp to ensure that the two profile ends to be welded form a right angle. The welding device is started, and the heating device is used to make the welding part of the profile reach the molten state. Under the action of a certain pressure, the molten parts of the two profiles are fused with each other to form a firm right-angle connection. The conventional cutting and welding method is inclined to the door and window frame, and the welding position is exposed on the outside, which results in poor appearance of the plastic profile wood-like door and window. The appearance of the adjacent frame connection position is quite different from the appearance of the mortise and tenon connection of the actual wooden door and window. The joint formed after the mortise and tenon connection of the wooden door and window is parallel to one of the frame rods.

[0003] A plastic steel window sash corner connection structure is disclosed in Chinese patent (publication number CN104453622A, publication date March 25, 2015). The connection of the first connecting profile is a 45° bevel cutting structure, and a mortise groove with a depth of 5-10 mm is processed on one end face of the first connecting profile. The connection of the second connecting profile is a 45° bevel cutting structure, and a connecting tenon structure matched with the mortise groove is provided on the second connecting profile. The first connecting profile and the second connecting profile are welded at the 45° bevel cutting structure to form a 90° right-angle butt joint structure, thereby improving the wood-like effect on the surface of the plastic steel window. Since the connecting tenon and the mortise groove are a contact structure rather than a direct connection structure, as the use time after installation is prolonged, the overall strength of the connecting tenon with small thickness is insufficient, and the connecting tenon end may be deformed and warped, which causes the connecting tenon to fail to maintain the fit with the mortise groove. Not only the appearance is greatly affected, but also the shielding and protection effect of the mortise groove is poor, and rainwater, dirt, etc. enters the profile through the mortise groove, accelerates the aging of the profile, and affects the durability.

[0011] Further, the second mechanical arm is provided with a milling rotary mechanism at the tail end, the milling rotary mechanism drives the milling mechanism to rotate to adjust the posture and switch the working states of the first and second milling cutters.

[0012] Further, the first and second mechanical arms are multi-degree-of-freedom mechanical arms, the first mechanical arm drives the saw blade to adjust the three-axis positions and three-axis inclination angles, and the second mechanical arm drives the milling cutter to adjust the three-axis positions and inclination angles.

[0013] Further, a material receiving groove is arranged below the clamping and conveying assembly, the top of the material receiving groove is open as an inlet end for receiving waste materials, and a conveying belt is connected to an outlet end of the material receiving groove.

[0014] The second object of the present application is to provide a processing method of the wood-like profile corner position saw-milling processing device, which utilizes the wood-like profile corner position saw-milling processing device as described in the first object, comprising:

[0015] The conveying mechanism grabs the whole profile and feeds it to the clamping mechanism, the sawing assembly adjusts the saw blade position between the two sets of clamping mechanisms to cut the whole profile, obtaining the first profile and the second profile;

[0016] The sawing assembly adjusts the saw blade posture to cut the end of the first profile and the end of the second profile, forming a first bevel welding surface and a connecting tenon extending from the bevel welding surface at the end of the first profile, and forming a second bevel welding surface at the end of the second profile;

[0017] The milling assembly adjusts the milling cutter posture to mill the second profile to form a tenon groove on one side of the second bevel welding surface, the thickness of the tenon groove is matched with the thickness of the connecting tenon, and a limiting groove is formed on the side of the tenon groove;

[0018] The output first profile and the second profile are combined at the corners, one side of the connecting tenon is fitted into the tenon groove, and the connecting tenon is inserted into the limiting groove on the side of the limiting groove, so that the first profile and the second profile form a right-angle butt joint structure.

[0021] Further, the second profile is first cut to form a bevel welding surface, and then milled along the direction parallel to the bottom surface of the tenon groove to remove part of the material to form the tenon groove and the limiting groove.

[0022] Further, after cutting the whole profile, the relative positions of the first profile and the second profile are adjusted to form a space for the operation of the sawing assembly and the milling assembly.

[0023] Compared with the prior art, the present application has the advantages and positive effects that:

[0024] In view of the problem that the connecting tenon and the tenon groove of the wood-like profile corner position are prone to deformation and warping, which reduces the aesthetic appearance and protection, the milling assembly forms a tenon groove at the end of the profile, and a limiting groove is formed on the side of the tenon groove, which can be connected to the side of the connecting tenon, effectively restraining the warping of the connecting tenon, solving the problem of insufficient strength of the connecting tenon leading to deformation, improving the aesthetic appearance, maintaining the good fit of the tenon groove and the connecting tenon, ensuring the protection of the connecting tenon to the tenon groove, and reducing the erosion of external factors to the profile.

[0025] By employing a multi-degree-of-freedom robotic arm to precisely adjust the posture of the saw blade and milling cutter, the sawing assembly can utilize a single saw blade to adjust its posture and establish multiple processing methods, meeting diverse sawing needs such as cutting and chamfering. Similarly, by adjusting the posture of the milling cutter, it can perform corresponding chamfering, milling to form tenon grooves and limiting grooves, ensuring the precise dimensions of the processed connecting tenons, tenon grooves, and limiting grooves.

[0027] When cutting the first profile, a step-by-step cutting method is adopted. First, a cut is made parallel to the length of the first profile to form a connecting tenon, which is equivalent to creating a stress relief point on the profile, allowing the internal stress of the profile to be initially dispersed in this process. Then, a cut is made parallel to the direction of the first beveled welding surface to remove the material end and form the first welding bevel. By releasing part of the stress before proceeding with subsequent cutting, this method of releasing some stress first effectively avoids excessive stress concentration in a certain area, protects the connecting tenon of the cantilever structure, reduces problems such as profile deformation and cracking caused by stress concentration, and improves the mechanical properties and service life of the profile.

DETAILED DESCRIPTION

[0036] Example 1

[0037] In a typical embodiment of the present application, as shown in Figures 1-6 a wood-like profile corner position sawing and milling processing device is provided.

[0038] In the prior art, the connecting tenon 11 is thin and has poor overall strength, and the end is prone to deformation and warping after long-term use. Since the connecting tenon 11 and the mortise 7 are in contact but not welded, if the connecting tenon 11 is thickened, the welding range of the profile corner position will be reduced, resulting in reduced welding strength. After the connecting tenon 11 deforms and warps, the fit is poor, resulting in poor protection of the mortise 7, and rainwater and dirt easily enter the interior of the profile to accelerate aging. Based on this, the present embodiment provides a wood-like profile corner position sawing and milling processing device, which forms a mortise 7 with a limiting groove 8 at the end of the profile by a milling assembly. The limiting groove 8 is located on the side of the mortise 7, and the side 6 of the connecting tenon is clamped by the limiting groove 8. The side 6 of the connecting tenon acts as a limiting block, and cooperates with the mortise 7 to form a clamping constraint, effectively limiting the warping of the connecting tenon 11, solving the problem of deformation caused by insufficient strength of the connecting tenon 11, and ensuring the stability of the connecting structure.

[0039] In the prior art, the connecting tenon 11 and the mortise 7 are in contact but not welded, bonded or directly connected and fixed, but remain in contact, and the constraint between the two is not tight enough. When external environmental factors such as temperature changes and humidity fluctuations occur, the plastic profile will expand and contract with heat. Due to the lack of tight and effective constraint between the connecting tenon 11 and the mortise 7, the connecting tenon 11 is prone to displacement and deformation during thermal expansion and contraction. Over time, the accumulated deformation manifests as warping. Moreover, in actual use, after the profile is used to make doors and windows, the doors and windows may be subjected to various accidental external force impacts, such as strong winds, collisions, etc. The connecting tenon 11 lacking tight constraint is also more prone to warping under these external forces. The connecting tenon 11 after warping loses the state of contact with the mortise 7, resulting in poor protection of the mortise 7, and rainwater and dirt easily entering the interior of the profile to accelerate aging.

[0040] As shown in Figures 1-4As shown, the wood-imitating profile corner position saw-milling processing device makes the tenon joint groove bottom surface 10 adhere to the connecting tenon 11, enhances the adhesion, and the limiting groove 8 structure can clamp one side of the connecting tenon 11, even if the connecting tenon 11 has a tendency to warp due to prolonged use, the limiting groove 8 can constrain the connecting tenon 11, avoid the connecting tenon 11 from separating from the tenon joint groove 7, guarantee the connection stability, strengthen the protection of the tenon joint groove 7, and reduce the erosion of external factors on the profile inside.

[0041] Specifically, as shown in the drawings, Figure 5 The wood-imitating profile corner position saw-milling processing device includes a clamping and conveying assembly 12, a sawing assembly, and a milling assembly.

[0042] The clamping and conveying assembly 12 is composed of a conveying mechanism and two groups of clamping mechanisms distributed at intervals, and each group of clamping mechanisms cooperates with the conveying mechanism. The clamping and conveying assembly 12 can stably convey and fix the profile, providing a reliable basis for subsequent sawing and milling processing. The conveying mechanism is responsible for accurately conveying the profile to the designated position, and the clamping mechanism firmly clamps the profile to prevent displacement during processing and ensure processing accuracy.

[0043] In this embodiment, the clamping and conveying assembly 12 can be formed by combining existing clamping mechanisms and conveying mechanisms. The conveying mechanism can adopt a roller type conveying belt 18 driven by a motor, and the stable operation of the conveying belt 18 is realized through gear transmission. The surface of the conveying belt 18 is made of rubber material to increase the friction between the profile and the conveying belt 18, ensuring that the profile does not slip during conveying. Adjustable guide baffles are provided on both sides of the conveying belt 18, which can be adjusted according to the width of different profiles to ensure that the profile is accurately conveyed to the designated position along the predetermined path. In other alternative embodiments, the conveying mechanism can also adopt the mode of clamping with mechanical claws by cooperating with electric cylinders, air cylinders, etc. After the mechanical claws clamp the profile, the electric cylinders, air cylinders, etc. are driven to move and adjust the position to meet the needs of sawing and milling.

[0044] For the clamping mechanism, each group of clamping mechanisms is composed of two movable clamping arms, and the clamping arms adopt a pneumatic control mode. The inner side of the clamping arm is provided with a resilient rubber pad, which can increase the friction with the profile to prevent the profile from slipping during clamping, and also avoid damaging the surface of the profile. The clamping arm is connected to the mounting base through a sliding rail and can be adjusted up and down according to the height of the profile. When clamping the profile, the clamping arm is driven inward by air pressure to tightly clamp the profile; when the profile needs to be loosened after processing, the air pressure drives the clamping arm to open outward in the opposite direction. The stability of the profile during sawing and milling processing is maintained.

[0045] When the whole profile is placed on the conveying belt 18, the conveying mechanism starts to work and conveys the profile to the predetermined position between the two sets of clamping mechanisms. After reaching the position, the conveying mechanism stops, and the clamping arms of the two sets of clamping mechanisms act simultaneously to tightly clamp the profile. At this time, the sawing assembly and the milling assembly can perform corresponding machining operations on the profile. During the machining process, the clamping mechanisms always maintain a firm clamping of the profile to prevent displacement and ensure machining accuracy. After machining is completed, the clamping mechanisms release the profile, and the conveying mechanism is started again to convey the machined profile to the next process.

[0046] As shown in Figure 6 The sawing assembly includes a first mechanical arm 13 and a sawing mechanism 14, and the end saw blade 19 of the sawing mechanism 14 changes its posture under the adjustment of the first mechanical arm 13. Through the first mechanical arm 13, flexible sawing operations can be performed on the profile located between the two sets of clamping mechanisms. On the one hand, the whole profile can be cut off, on the other hand, a connecting tenon 11 can be formed at the end of a profile, and a sawing operation for a bevel surface used for welding can also be performed. Through precise adjustment of the mechanical arm, the accuracy of sawing and the dimensional accuracy of the connecting tenon 11 can be ensured.

[0047] Specifically, the first mechanical arm 13 can be a six-axis industrial mechanical arm with high degrees of freedom and high precision. Servo motors are used to drive the joints, and high-precision reducers are used to achieve precise angle control and position positioning. The base of the first mechanical arm 13 is fixed on a movable sliding table, which is connected to the rack of the processing equipment through a linear guide rail, and moves forward and backward by a servo motor driven ball screw to expand the working range of the first mechanical arm 13. The arm span of the first mechanical arm 13 is designed according to the processing requirements, which can cover the profile machining area between the two sets of clamping mechanisms.

[0048] It can be understood that in other alternative embodiments, a combination of multiple screw block mechanisms and swing cylinders can be used to establish the first mechanical arm 13. Multiple screw block mechanisms are used to form a multi-axis mechanical arm, and multiple swing cylinders are connected in series to form the required posture adjustment mechanism.

[0049] The sawing mechanism 14 is installed at the end of the first mechanical arm 13 and mainly consists of a saw blade 19, a saw blade 19 motor and a saw blade 19 mounting seat. The saw blade 19 is made of hard alloy material, has high hardness and wear resistance, and the diameter is selected according to the profile to be sawed, such as 300 mm, etc., which is suitable for sawing various plastic wood-like profiles. The saw blade 19 motor is a high-speed variable frequency motor, which can adjust the speed according to the material and thickness of the profile, and the highest speed is also selected according to the demand, which can adopt a saw blade 19 motor with a highest speed of 5000 rpm. The saw blade 19 mounting seat is connected to the end of the first mechanical arm 13 through a rotatable joint, which is driven by a motor and can realize the angle adjustment of the saw blade 19 within 360°, meeting the sawing requirements of different angles.

[0050] The first mechanical arm 13 and the sawing mechanism 14 are configured with corresponding numerical control systems, and the motion trajectory of the mechanical arm and the sawing parameters are set by programming. The operator can input the sawing length, angle, cutting speed and other parameters on the control panel, and the numerical control system accurately controls the action of the mechanical arm and the sawing mechanism 14 according to these parameters. During sawing, the mechanical arm moves according to the preset trajectory, accurately positions the saw blade 19 to the sawing position of the profile, and adjusts the angle and sawing speed of the saw blade 19 as needed. For example, when cutting off the whole profile, the mechanical arm cuts vertically downwards; when forming the connecting tenon 11, the mechanical arm adjusts the angle and motion trajectory of the saw blade 19 according to the design requirements, to ensure the size accuracy and shape precision of the connecting tenon 11.

[0051] As shown in Figure 6 The milling assembly is composed of a second mechanical arm 15 and a milling mechanism 16, and the end milling cutter 20 of the milling mechanism 16 changes its posture under the adjustment of the second mechanical arm 15. The milling assembly is mainly used to form the tenon groove 7 and the limiting groove 8 at the end of another profile. The multi-degree-of-freedom adjustment function of the second mechanical arm 15 enables the milling cutter 20 to accurately mill according to the design requirements, ensuring that the tenon groove bottom surface 10 is in close contact with the connecting tenon 11, and at the same time, the limiting groove 8 is accurately formed on the side of the tenon groove 7 to effectively constrain the connecting tenon 11.

[0052] Specifically, the second mechanical arm 15 can also be a six-axis industrial robot, and each joint is driven by a high-performance servo motor, which can realize extremely accurate angle control and position positioning in cooperation with a high-precision planetary reducer. The base of the second mechanical arm 15 is fixed on a lifting platform that can move up and down along the guide rail, and the lifting platform is connected to the main frame of the processing equipment through a high-precision linear guide rail, and the lifting action is completed by a servo motor driven ball screw, which greatly expands the working range of the mechanical arm in the vertical direction. The maximum extension length of the second mechanical arm 15 is selected according to the demand, which is sufficient to flexibly cover the profile processing area between the two sets of clamping mechanisms, ensuring that the profile at different positions can be milled.

[0053] The milling mechanism 16 is installed at the end of the second mechanical arm 15, mainly composed of a milling cutter 20, a milling cutter motor and a milling cutter mounting seat. The milling cutter 20 is made of superhard alloy material, which can meet the processing requirements of the profile in terms of hardness and wear resistance. The diameter and shape of the milling cutter 20 can be designed according to the requirements. For example, the milling cutter 20 with a cross-sectional shape matching the limiting groove 8 can adapt to the complex milling requirements of various imitation wood profiles. The milling cutter motor adopts a high-frequency high-speed motor, which can accurately adjust the speed through a frequency converter according to the material properties and processing requirements of the profile. The milling cutter mounting seat is connected to the end of the second mechanical arm 15 through a rotating joint with 360° rotation function as the milling rotary mechanism. The rotating joint is driven by an independent servo motor, which can realize accurate adjustment of the milling cutter 20 at any angle, fully meeting the milling requirements of the mortise and tenon groove 7 and the limiting groove 8 at different angles and shapes.

[0054] As shown in Figure 5 and Figure 6 , the milling mechanism 16 adopts a double-milling cutter design, which has clear division of labor and improves efficiency. The milling mechanism 16 includes a first milling cutter and a second milling cutter that operate independently and are located at different ends of the milling mechanism 16. The first milling cutter is responsible for forming the mortise and tenon groove 7 and the limiting groove 8, which are key structures for connecting the angle position of the imitation wood profile. The second milling cutter is used to chamfer the end of the connecting tenon 3, which not only optimizes the appearance of the connecting tenon 11, but also avoids safety hazards and component damage caused by sharp corners during subsequent installation and use. The double milling cutters 20 operate independently and can perform different processing procedures at the same time, greatly improving processing efficiency and shortening overall processing time.

[0055] Different processing tasks are handled by special milling cutters 20, which avoids precision errors that may be caused by frequent replacement of single milling cutters 20. When forming the mortise and tenon groove 7 and the limiting groove 8, the first milling cutter can accurately mill according to preset parameters, ensuring the size accuracy of the mortise and tenon groove 7 and the position accuracy of the limiting groove 8, thereby ensuring good cooperation with the connecting tenon 11.

[0056] As shown in Figure 5 and Figure 6 , the milling rotary mechanism at the end of the second mechanical arm 15 can drive the milling mechanism 16 to rotate, which not only adjusts the posture of the milling cutter 20, but also switches the working state of the first milling cutter and the second milling cutter. This allows quick switching of processing procedures without replacing the entire milling mechanism 16 at the same processing location. After milling the mortise and tenon groove 7 and the limiting groove 8, the second milling cutter can be quickly switched to the working position through the milling rotary mechanism to chamfer the end of the connecting tenon 11, improving the continuity of processing and the efficiency of equipment use.

[0057] A set of numerical control system is equipped for the milling assembly, and professional programming software is used to set the motion trajectory of the mechanical arm and the milling process parameters. The operator can conveniently input the size, depth, angle and other processing parameters of the mortise groove 7 and the limiting groove 8 on the operation panel, and the numerical control system will accurately calculate and control each action of the mechanical arm and the milling mechanism 16 according to these parameters. During the milling process, the mechanical arm moves strictly according to the preset trajectory, accurately positions the milling cutter 20 to the milling position of the profile, and adjusts the angle and milling speed of the milling cutter 20 in real time according to the processing requirements. When milling the mortise groove 7, the mechanical arm stably cuts according to the predetermined depth and width; when processing the limiting groove 8, the mechanical arm accurately adjusts the angle and motion path of the milling cutter 20 according to the design requirements, to ensure that the size and shape of the limiting groove 8 meet the design standards, thereby realizing effective constraint of the connecting tenon 11.

[0058] The first mechanical arm 13 and the second mechanical arm 15 are both multi-degree-of-freedom mechanical arms, which can adjust the three-axis position and three-axis inclination of the saw blade 19 and the milling cutter 20, giving the processing device high flexibility and accuracy. During sawing, the first mechanical arm 13 can accurately adjust the position and angle of the saw blade 19 according to the shape, size and processing requirements of the profile, to ensure that the cut connecting tenon 11 is accurate in size and meets the design requirements in shape. Similarly, the second mechanical arm 15 can also realize high-precision processing of the mortise groove 7 and the limiting groove 8 through multi-degree-of-freedom adjustment when driving the milling cutter 20 to mill, to meet the complex processing requirements of different wood-like profiles. The application of multi-degree-of-freedom mechanical arms enables the processing device to adapt to the processing of different specifications and shapes of wood-like profiles. Whether it is a regular-sized profile or a special-shaped profile with special design requirements, the mechanical arm can be flexibly adjusted to complete the processing task, greatly expanding the application range of the device.

[0059] Through the processing of the wood-like profile by the wood-like profile angle position sawing and milling processing device, the limiting groove 8 restricts the side surface 6 of the connecting tenon, significantly enhancing the stability of the connection between the connecting tenon 11 and the mortise groove 7, improving the connection strength of the wood-like profile angle position, making the entire profile structure more firm and prolonging the service life. It ensures the good fit of the connecting tenon 11 and the mortise groove 7, avoids appearance defects caused by the deformation and warping of the connecting tenon 11, further improves the real wood effect of the wood-like profile, meets the pursuit of consumers for aesthetics, and the optimized connection structure effectively blocks rainwater, dirt and other intrusions into the profile, slows down the aging speed of the profile, improves durability, and reduces maintenance costs in the later period.

[0060] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the side surface 6 of the connecting tenon refers to one side along the length direction of the profile where the connecting tenon 11 is located, and the end surface 3 of the connecting tenon refers to one end along the length direction of the profile where the connecting tenon 11 is located. The tenon groove bottom surface 10 is the bottom surface of the groove recessed on the surface of the profile formed after milling the profile by the milling assembly, the tenon groove 7 side surface refers to the side away from the end along the length direction of the profile where it is located, which is also the side surface of the groove, and the limiting groove 8 is the groove distributed on the side surface of the tenon groove 7, which is recessed relative to the side surface of the tenon groove 7. The cross-sectional shape of the limiting groove 8 is matched with the cross-sectional shape of the side surface 6 of the connecting tenon to achieve clamping. The clamping with the side surface of the connecting tenon 11 is achieved through this matching relationship, thereby effectively restraining the connecting tenon 11 to prevent it from being warped, and ensuring the stability and reliability of the angle position connection of the imitation wood profile.

[0061] The work switching of different milling cutters 20 is realized through the rotation of the milling rotation mechanism, avoiding the space occupation problem possibly caused by setting multiple independent milling mechanisms 16, and making the structure of the whole processing device more simple and efficient.

[0062] As shown in Figure 5 and Figure 6 , a material receiving groove 17 is arranged below the clamping and conveying assembly 12, the top is open as an inlet end for receiving waste, and the outlet end is connected to a conveying belt 18. The waste generated during sawing and milling processes, such as plastic chips, metal scraps, and material heads, can directly fall into the material receiving groove 17, and then be conveyed to a designated position by the conveying belt 18 for centralized processing, realizing automatic collection and conveying of waste, avoiding accumulation of waste in the processing area, maintaining the cleanliness of the working environment, and reducing the workload of manual waste cleaning, thereby improving production efficiency. Timely cleaning of waste prevents waste from entering critical parts of the processing equipment, such as the joints of the mechanical arm, the transmission components of the saw blade 19 and the milling cutter 20, thereby avoiding equipment failure caused by waste accumulation, prolonging the service life of the equipment, and ensuring the continuity and stability of the processing process.

[0063] Embodiment 2

[0064] In another typical embodiment of the present application, as shown in Figures 1-6 , a processing method of an imitation wood profile angle position sawing and milling processing device is given, which utilizes the imitation wood profile angle position sawing and milling processing device as in embodiment 1.

[0065] A processing method of an imitation wood profile angle position sawing and milling processing device, comprising:

[0066] The conveying mechanism grasps the whole profile for feeding to the clamping mechanism, the sawing assembly adjusts the position of the saw blade 19 between the two sets of clamping mechanisms to cut off the whole profile, obtaining a first profile 1 and a second profile 2;

[0067] The sawing assembly adjusts the attitude of the saw blade 19 to cut the ends of the first profile 1 and the second profile 2 to form the first beveling welding surface 5 and the connecting tenon 11 extending from the beveling welding surface at the end of the first profile 1, and to form the second beveling welding surface 9 at the end of the second profile 2;

[0068] The milling assembly adjusts the attitude of the milling cutter 20 to mill the second profile 2 to form the mortise groove 7 on one side of the second beveling welding surface 9, the thickness of the mortise groove 7 being adapted to the thickness of the connecting tenon 11, and to form the limiting groove 8 on the side of the mortise groove 7;

[0069] The first profile 1 and the second profile 2 are output, the first beveling welding surface 5 and the second beveling welding surface 9 are assembled at an angle, one side of the connecting tenon 11 is fitted to the mortise groove 7, and the connecting tenon 11 is clamped into the limiting groove 8 on the side of the limiting groove 8, so that the first profile 1 and the second profile 2 form a right-angle butt joint structure.

[0070] Unlike the existing single machining mode, the profile can only be cut off first, and then the small sections of the profile after cutting off are loaded and clamped respectively, and then sawing and milling operations are sequentially carried out. The existing single machine mode has many drawbacks: on the one hand, multiple loading and clamping not only consumes a lot of time, but also introduces positioning errors every time the profile is loaded, making it difficult to ensure machining accuracy; on the other hand, frequent manual operation or equipment switching actions increase the complexity of operation and the probability of error, reducing overall production efficiency.

[0071] To this end, as shown in Figure 5 and Figure 6 In the machining method of the wood-like profile corner position sawing and milling processing device provided in the embodiment, the whole profile material can be directly machined, the whole profile is accurately grabbed by the conveying mechanism and sent to the clamping mechanism, and the position of the profile is ensured to be stable. Then the sawing assembly cuts off the profile between the two clamping mechanisms to obtain two profiles to be machined, providing a basic unit for subsequent machining, and orderly loading and cutting ensure the starting accuracy of machining, avoid errors caused by multiple loading, and ensure the stability of the profile position.

[0072] The sawing assembly continues to adjust the attitude of the saw blade 19 to form the connecting tenon 11 and the first beveling welding surface 5 at the end of the first profile 1, and to form the second beveling welding surface 9 at the end of the second profile 2. Then the milling assembly processes the second profile 2 to form the mortise groove 7 and the limiting groove 8 on one side of the second beveling welding surface 9. The step-by-step processing method enables each processing step to focus on the formation of a specific structure, and since there is no need to frequently replace the profile and adjust the positioning of the equipment, the processing process is more coherent, the components can operate stably according to the preset program, and the machining accuracy of the connecting tenon 11, the beveling welding surface, the mortise groove 7 and the limiting groove 8 and other key structures is improved.

[0073] Finally, the chamfered welding surfaces of the first profile 1 and the second profile 2 are assembled, the connecting tenon 11 is matched with the mortise 7, the connecting tenon 11 is clamped into the limiting groove 8, a stable right-angle butt joint structure is formed, the final assembly link of the entire processing flow is completed, and the stability of the angle position connection of the imitation wood profile is ensured.

[0074] By precisely adjusting the attitudes of the saw blade 19 and the milling cutter 20 through each component, the size accuracy of the connecting tenon 11, the mortise 7 and the limiting groove 8 is ensured, the problem of large size deviation and loose connection of the connecting structure in traditional processing is solved, the thickness of the connecting tenon 11 and the mortise 7 is adapted, and the connection strength is improved. The design and processing of the limiting groove 8 effectively solve the problem that the connecting tenon 11 is easy to be raised and causes unstable connection. By clamping the connecting tenon 11 into the limiting groove 8, the displacement of the connecting tenon 11 is limited, and the stability of the angle position connection of the profile is enhanced. The clear processing steps and the cooperative work of each component avoid confusion and repeated operation in the processing process, improve the processing efficiency, and reduce the processing time and labor cost compared with the traditional processing method.

[0075] Before cutting the first profile 1 to form the connecting tenon 11, the end is milled to form a chamfer 4 by using a milling assembly. At this time, the first profile 1 has not yet formed the connecting tenon 11, and the overall stability is good when processing the chamfer 4. The chamfer 4 treatment not only can avoid the sharp corners at the end of the connecting tenon 11 causing safety hazards in subsequent processing and use, but also can make the connection of the connecting tenon 11 and the mortise 7 more closely. By precisely controlling the parameters of the milling assembly, the size and angle of the chamfer 4 can be ensured to meet the design requirements, further improving the precision and quality of the connecting part.

[0076] Figure 1 、 Figure 3 The structure of the end of the first profile 1 and the second profile 2 is shown. When cutting the first profile 1, the connecting tenon 11 is first cut parallel to the length direction to form a connecting tenon 11, which can use the complete length of the profile as a reference to ensure the length accuracy of the connecting tenon 11. The side surface 6 of the connecting tenon naturally forms a limiting block that can cooperate with the limiting groove 8. Then, the material head is cut to form a chamfered welding surface parallel to the first chamfered welding surface 5, the sequence of the two cutting ensures that the size of the connecting tenon 11 and the chamfered welding surface can be precisely controlled, avoids the size deviation caused by one-time cutting, and improves the processing precision of the end structure of the profile, providing a better foundation for subsequent connection with the second profile 2.

[0077] The operation sequence of cutting the end of the first profile 1 is first cut parallel to the length direction of the first profile 1 to form a connecting tenon 11, which is equivalent to manufacturing a stress release point on the profile, so that the internal stress of the profile is preliminarily dispersed in this process. Then cut parallel to the direction of the first bevel cutting welding surface 5 to remove the material head to form the first welding bevel cutting surface. Through this way of releasing part of the stress first and then cutting, the stress is effectively avoided from being excessively concentrated in a certain area, the connecting tenon 11 of the cantilever structure is protected, and the problems of profile deformation, cracking and other problems caused by stress concentration are reduced, thereby improving the mechanical properties and service life of the profile.

[0078] The second profile 2 is first cut to form a bevel cutting welding surface, and then part of the material is milled along the direction of the parallel tenon groove bottom surface 10 to form a tenon groove 7 and a limiting groove 8. The layered milling method makes the processing process more precise, can better control the depth, width of the tenon groove 7 and the position and size precision of the limiting groove 8, ensures the perfect fit of the connecting tenon 11 of the first profile 1, and improves the precision and stability of the angle position connection of the wood-like profile.

[0079] After cutting off the whole profile, the relative positions of the first profile 1 and the second profile 2 are adjusted to form a space for the sawing assembly and the milling assembly to operate. The processing space is planned in advance, so that the sawing assembly and the milling assembly can quickly take their positions and start working, avoiding the equipment adjustment and waiting time caused by improper profile position, and improving the overall processing efficiency.

[0080] The milling of the second profile 2 precisely forms the tenon groove 7 and the limiting groove 8, and the closely fitted structure enables the connecting tenon 11 to be effectively constrained by the limiting groove 8 when subjected to external force, preventing the connecting tenon 11 from being raised or displaced, thereby greatly improving the stability of the angle position connection of the wood-like profile and ensuring that the entire profile structure remains firm during long-term use.

[0081] For the assembly structure of the connecting tenon 11 of the first profile 1 and the tenon groove 7, as shown in Figure 1 , Figure 4 The first bevel cutting welding surface 5 and the second bevel cutting welding surface 9 are aligned and heated for angle assembly. In the process of angle assembly, the connecting tenon 11 on the first profile 1 is inserted into the tenon groove 7 of the second profile 2, ensuring that one side of the connecting tenon 11 closely fits the tenon groove bottom surface 10, achieving preliminary connection positioning. Then, the side of the connecting tenon 11 facing the limiting groove 8 is accurately inserted into the limiting groove 8, which effectively prevents the connecting tenon 11 from being raised or displaced during use, further enhancing the stability of the connection. The assembled first profile 1 and second profile 2 are as shown in Figure 4 .

The present application can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the present application.
