Description

Technical Field

[0001] The utility model relates to the field of profile processing, in particular to a door frame profile sawing structure with a grinding allowance. Background Art

[0002] When making door frames from plastic profiles, the ends of the profiles need to be cut, creating grooves at the corners to form the door frames. Large cutting machines are often equipped with angle scales, allowing precise adjustment of cutting angles, such as 45-degree cuts, to accommodate different door frame designs. Cutting accuracy is a key indicator of cutting quality, and includes factors such as repeatable length accuracy, flatness of the cut surface, and maximum deviation of the cutting angle.

[0003] The roughness of the cut surface significantly impacts the appearance and service life of the door frame. Using the appropriate cutting process and cutting tools can reduce surface roughness and improve the overall quality of the door frame. When cutting the door frame profile, an L-shaped groove is formed at the end corner. This L-shaped groove is formed by cutting along the axial direction of the door frame profile and along its thickness, with the cuts in these two directions intersecting. This removes material at the end corner to create the desired L-shaped groove. Since the cutting depth along the axial direction of the end is inconsistent with the cutting depth along the thickness direction, and the cutting depth along the axial direction of the door frame profile is larger, the saw blade corresponding to the cutting position is more severely worn and the saw blade wears faster, so it needs to be sharpened. As the number of sharpening times increases, the outer diameter of the saw blade will gradually decrease, causing the saw blade's cutting depth of the door frame profile to gradually decrease. Although excessive cutting is generally performed during the initial cutting, so that the saw blade after sharpening can still meet the cutting range requirements, the saw blade will still wear faster, and the cutting saw blade in the thickness direction and the cutting saw blade along the axial direction of the door frame profile cannot be replaced synchronously, which increases the frequency of shutdown for replacement, affects production efficiency, and the durability of the saw blade is difficult to meet the requirements.

DETAILED DESCRIPTION

[0025] In a typical embodiment of the present invention, Figure 1-Figure 2 As shown, a door frame profile sawing structure with a grinding allowance is proposed.

[0026] When saw blades in door frame profile sawing structures wear, the cutting depth decreases, requiring frequent blade replacement. This not only increases costs but also affects production efficiency. Based on this, this embodiment provides a door frame profile sawing structure with a sharpening margin. This mechanism aims to extend the life of the saw blade through a compensation mechanism and reduce the frequency of replacement due to asynchronous wear.

[0027] like Figure 1 As shown, the door frame profile sawing structure with a grinding allowance mainly includes a base frame 1, a clamping mechanism, a sawing assembly, and a cutting mechanism 2. The base frame 1 serves as the supporting foundation for the entire sawing structure. The clamping mechanism is mounted on the base frame 1 and is provided with a clamping portion for accommodating the door frame profile. The sawing assembly includes a slewing mechanism, a three-axis moving mechanism 11, a first sawing mechanism 6, and a second sawing mechanism 7. The slewing mechanism is mounted on the base frame 1, and its output end is connected to the translation base 12, which can drive the entire sawing assembly to rotate to meet the needs of sawing at different angles. The slewing mechanism includes a slewing drive mechanism 13 and a slewing guide mechanism. The slewing guide mechanism ensures the stability of the translation base 12 during rotation.

[0028] The three-axis motion mechanism 11 is mounted on the output end of the slewing mechanism via a translation base 12. The three-axis motion mechanism 11 comprises three mutually perpendicular translation mechanisms, enabling precise three-dimensional movement of the sawing carrier 10. The sawing carrier 10 is connected to the output end of the three-axis motion mechanism 11 and is used to mount the second sawing mechanism 7 and the first sawing mechanism 6.

[0029] The first sawing mechanism 6 is mounted on a compensating slide 8, which is slidably mounted on a saw carrier 10 and can move axially along the saw blade of the second sawing mechanism 7 to compensate for the reduced cutting depth caused by saw blade wear. The compensating slide 8 is moved by a compensating drive 9. The first and second sawing mechanisms 6 and 7 each have a saw blade, and their axes are perpendicular, forming a cross-cutting path.

[0030] The cutting mechanism 2 includes a cutting drive and a cutting guide mechanism, which is used to cut the door frame profile after the sawing is completed. The cutting drive is installed on the base frame 1 through the cutting guide mechanism and can be raised and lowered vertically to adjust the height of the cutting saw blade.

[0031] An L-shaped groove is formed by cutting at the corner position of the end of the door frame profile. Since the cutting depth along the axial direction of the end is inconsistent with the cutting depth in the thickness direction, and the cutting depth along the axial direction of the door frame profile is large, the saw blade corresponding to the cutting position is more severely worn and the saw blade wears faster, so it needs to be sharpened. After sharpening, the saw blade size is reduced, which will lead to a smaller sawing coverage area, making it difficult to meet the cutting depth requirements. There is a problem that the door frame profile is left with residue after cutting, resulting in the inability to form an L-shaped groove. In this embodiment, the saw blade position is accurately adjusted by the cooperation of the compensation slide 8 and the compensation drive 9. After the saw blade is sharpened and the diameter is reduced, the saw blade position is adjusted to reduce the distance between the saw blade axis and the door frame profile to be sawed, thereby ensuring that the saw blade after sharpening can still meet the cutting depth requirements.

[0032] The output end of the first sawing mechanism 6 is a first saw blade, and the output end of the second sawing mechanism 7 is a second saw blade. The cutting path of the first saw blade intersects with the cutting path of the second saw blade.

[0033] Since the first saw blade cuts the door frame profile along the axial direction of the door frame profile, it wears faster than the second saw blade. The first saw blade and the second saw blade need to be replaced separately due to asynchronous wear, which increases the frequency of replacement. In this embodiment, the compensation mechanism is used to extend the service life of the first saw blade and reduce the frequency of replacement.

[0034] like Figure 1 and Figure 2 As shown, the compensating slide 8 is mounted on the saw carrier 10 via a slide rail mechanism. The movement of the slide rail mechanism is parallel to the direction of the sharpening compensation of the first sawing mechanism 6. The slide rail mechanism ensures that the compensating slide 8 can move smoothly along a predetermined path, meeting the sharpening compensation requirements of the first sawing mechanism 6. After the first saw blade is sharpened, its outer diameter decreases. By controlling the movement of the compensating slide 8, the axis of the first saw blade is brought closer to the door frame profile held by the clamping portion, ensuring the cutting depth. After replacing the new first saw blade, the outer diameter of the first saw blade returns to its original size, and the compensating slide 8 is controlled to move so that the axis of the first saw blade is away from the door frame profile held by the clamping portion.

[0035] As the saw blade wears, its cutting depth gradually decreases. The compensating slide 8, via the slide rail mechanism, precisely moves along the direction of the first sawing mechanism 6 to compensate for the sharpening loss, thereby adjusting the saw blade's position and ensuring the desired cutting depth is always met. This extends the saw blade's service life, reduces the problem of insufficient cutting depth due to blade wear, and improves sawing accuracy and efficiency.

[0036] Specifically, such as Figure 1As shown, the compensation drive member 9 is composed of a compensation drive motor and a lead screw slider mechanism. The compensation drive motor is installed on the sawing carrier 10, and the lead screw is rotatably installed on the sawing carrier 10 through a support, and the slider of the lead screw slider mechanism is connected to the compensation slide 8. The output end of the compensation drive motor is connected to the lead screw transmission to drive the lead screw to rotate. The transmission connection can adopt a synchronous belt mechanism, which uses a combination of a synchronous belt and a synchronous wheel to transmit the rotation of the compensation drive motor to the lead screw, drive the lead screw to rotate to adjust the position of the slider, and provide accurate and controllable moving power for the compensation slide 8. Driven by the motor, the lead screw rotates, driving the slider (and the connected compensation slide 8) to move along the lead screw axis, thereby realizing precise adjustment of the saw blade position. The dynamic adjustment of the saw blade position is realized, the stability of the cutting depth is ensured, and the controllability and precision of the sawing process are improved.

[0037] like Figure 1 and Figure 2 As shown, the first sawing mechanism 6 and the second sawing mechanism 7 are located on either side of the sawing carrier 10, with the output ends being the first saw blade and the second saw blade, respectively. The axes of the two saw blades are perpendicular, forming a cross-cutting path. This cross-cutting path enables multi-angle and multi-directional sawing of door frame profiles, creating the desired L-shaped grooves. This improves the flexibility and adaptability of the sawing mechanism, making the sawing of door frame profiles more efficient and precise.

[0038] like Figure 2 As shown, the slewing mechanism includes a slewing drive mechanism 13 and a slewing guide mechanism. The slewing drive mechanism 13 is mounted on the base frame 1, with its output end connected to the translating base 12. The slewing guide mechanism includes a slewing bracket 16 and a slewing slide 15. The slewing slide 15 is mounted on the translating base 12, and the slewing bracket 16 is provided with a slewing slider that slidably engages with the slewing slide 15. This provides smooth slewing motion for the sawing assembly, ensuring a stable posture and position during the sawing process. This enhances the stability and reliability of the sawing structure, and improves the smoothness and precision of the sawing process.

[0039] Specifically, the slewing mechanism provides smooth slewing motion for the sawing assembly, ensuring it maintains a stable posture and position during the sawing process. The slewing drive mechanism 13 and slewing guide mechanism are mounted on the chassis 1 and the translating base 12, respectively. The output end of the slewing drive mechanism 13 is connected to the translating base 12 to ensure its rotational motion. The slewing guide mechanism's slewing rail 15 is securely mounted on the translating base 12, providing a path for the sliding movement of the slewing bracket 16.

[0040] On either side of the rotary axis at the output end of the rotary drive mechanism 13 are slewing rails 15, each fitted with a slewing slider. The slewing rails 15 are arc-shaped, their axes collinear with the slewing axis of the translation base 12. This allows the three-axis motion mechanism 11 above the slewing mechanism to rotate stably, utilizing the load-bearing and guiding functions of the arc-shaped rails to assist in the slewing adjustment above.

[0041] When a rotary motion is required, the rotary drive mechanism 13 is started. The rotary drive mechanism 13 can be a rotary motor, a rotary cylinder or other rotary parts. The output end of the rotary drive mechanism 13 starts to rotate, driving the translation base 12 connected thereto to rotate together.

[0042] As the translation base 12 rotates, the swivel slider on the swivel bracket 16 slides on the swivel rail 15. The sliding fit ensures that the swivel bracket 16 can move smoothly following the rotation of the translation base 12 while maintaining a certain stability and accuracy.

[0043] The rotation of the slewing mechanism allows the saw assembly to be adjusted in both posture and position. For example, when cutting different sections of a door frame profile, the saw assembly can be rotated to align with the desired location. Furthermore, the slewing mechanism can be used to adjust the cutting angle to accommodate door frame profiles of varying shapes and sizes.

[0044] When the sawing task is complete, the rotary drive mechanism 13 needs to be stopped. At this point, the output end of the drive mechanism stops rotating, and the translation base 12 and rotary bracket 16 also stop moving. After stopping the rotary mechanism, it needs to be reset to return the sawing assembly to its initial position. At the same time, the rotary mechanism needs to be cleaned and maintained to ensure its long-term stable operation.

[0045] like Figure 1 As shown, the three-axis movement mechanism 11 comprises three sequentially connected translation mechanisms, each perpendicular to the other. This enables precise movement of the sawing carrier 10 in three dimensions, ensuring that the saw blade can be accurately positioned at any position within the door frame profile. This improves the flexibility and precision of the sawing process, making door frame profile cutting more efficient and accurate.

[0046] In this embodiment, the three-axis movement mechanism 11 is composed of three translation mechanisms connected in sequence, and the three translation mechanisms are perpendicular to each other in space and correspond to the X-axis, Y-axis and Z-axis directions respectively.

[0047] The X-axis translation mechanism primarily consists of a motor, reducer, lead screw, nut, guide rails, and sliders. The motor drives the lead screw through the reducer, which in turn achieves linear motion. The guide rails and sliders ensure smooth and precise movement. The X-axis translation mechanism is responsible for horizontally moving the sawing carrier 10, enabling it to cut along the axial length of the door frame profile.

[0048] Similar to the X-axis translation mechanism, the Y-axis translation mechanism also includes components such as a motor, a reducer, a lead screw, a nut, a guide rail, and a slider. However, the Y-axis translation mechanism is positioned perpendicular to the X-axis and is used to move the sawing carrier 10 in a horizontal plane perpendicular to the X-axis. The Y-axis translation mechanism enables two-dimensional movement of the sawing carrier 10 on the horizontal plane, further expanding the saw blade's positioning range.

[0049] The Z-axis translation mechanism also includes a motor, reducer, lead screw, nut, guide rail, slider, and other components, but it is arranged perpendicular to the X- and Y-axes and is used to vertically move the saw carrier 10. The Z-axis translation mechanism allows the saw blade to be fine-tuned in the vertical direction to accommodate door frame profiles of varying thicknesses or heights, ensuring accurate and stable sawing.

[0050] When the saw carrier 10 needs to be moved, the control system sends instructions to the three-axis movement mechanism 11. These instructions typically include parameters such as target position, movement speed, and acceleration. After receiving the instructions, the three-axis movement mechanism 11 analyzes and processes them to determine the movement mode and parameters of each translation mechanism.

[0051] Once the motion pattern and parameters are determined, the three translation mechanisms begin working in tandem. The X-axis translation mechanism moves the sawing carrier 10 horizontally, the Y-axis translation mechanism moves it perpendicular to the X-axis, and the Z-axis translation mechanism performs fine adjustments in the vertical direction. By precisely controlling the speed and acceleration of each translation mechanism, the sawing carrier 10 is ensured to be moved smoothly and accurately to the target position.

[0052] During the movement, the three-axis moving mechanism 11 monitors the movement status and position information of each component in real time. If any abnormality or deviation is found, the control system will immediately make feedback adjustments to ensure that the sawing carrier 10 can always stay on the correct track.

[0053] Once the saw carrier 10 reaches its target position, the sawing mechanism begins cutting the door frame profile. During the sawing process, the three-axis motion mechanism 11 makes fine adjustments as needed to ensure accurate and stable cutting. Upon completion of the sawing task, the three-axis motion mechanism 11 returns to its initial position, awaiting the next instruction.

[0054] like Figure 1 As shown, the cutting mechanism 2 includes a cutting drive and a cutting guide mechanism. The output end of the cutting drive is connected to a cutting saw blade, which is mounted on the base frame 1 through a cutting guide mechanism. The cutting saw blade can cut the frame profile by rotating. The cutting mechanism 2 is also connected to a cutting lifting mechanism 3 to drive the cutting saw blade to rise and fall relative to the clamping part. Before using the sawing assembly to saw the door frame profile, it is necessary to cut the door frame profile flush and cut the door frame profile into the required length. The cutting guide mechanism and the cutting lifting mechanism 3 ensure the stability and accuracy of the cutting process. The cutting efficiency and accuracy of the door frame profile are improved, ensuring that the size of the door frame profile after cutting meets the requirements.

[0055] The clamping mechanism includes a movable clamping plate 4 and a fixed clamping plate 5, with the fixed clamping plate 5 vertically positioned above the movable clamping plate 4. A clamping drive is connected to the movable clamping plate 4, forming a clamping portion with the fixed clamping plate 5. The position of the clamping portion matches that of the cutting mechanism 2. When the cutting mechanism 2 is raised to the top of the path by the cutting lifting mechanism 3, it can cut the door frame profile contained in the clamping portion. Furthermore, when the cutting mechanism 2 is raised to the bottom of the path by the cutting lifting mechanism 3, it can avoid the door frame profile contained in the clamping portion.

[0056] At the same time, the clamped door frame profile is placed within the working range of the sawing mechanism. Clamping the door frame profile ensures that it remains stable during the sawing process, improving the stability and safety of the sawing process and ensuring the quality of the sawing.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
