Description

A grooving processing device for aluminum alloy windows Technical Field

[0001] This invention relates to the field of aluminum alloy window technology, specifically to a grooving processing device for aluminum alloy windows. Background Technology

[0002] The frame of aluminum alloy doors and windows consists of two aluminum profiles and a thermal insulation layer between them. For 45° sliding sashes where the cavity structure is too small to be properly assembled at the corners, reinforcing ribs are typically added to the inside of the aluminum profiles, and then grooves for connecting corner brackets are cut into these ribs. Since the reinforcing ribs are installed on the inner surface of the aluminum profiles, and the space between the two profiles is very limited, traditional door and window grooving devices are difficult to use in such a confined space. Therefore, tools such as electric saws are used to groove the reinforcing ribs on individual aluminum profiles before assembling the aluminum alloy door and window frame, and then the aluminum profiles are assembled. For example, Chinese utility model patent CN215746759U discloses a door and window frame cutting machine, which includes a box, a waste box, a cutting saw and a clamping device. The top of the box is provided with a worktable, and a pressing device is provided on the worktable. A support frame is provided on one side of the box, and a cutting saw is slidably installed on the support frame. A scraper is provided on one side of the pressing device on the worktable, and the two sides of the scraper are slidably connected to the box.

[0003] When using existing processing equipment, including the aforementioned device, to groove the reinforcing ribs, a misalignment often occurs at one end of the assembled aluminum alloy door and window frame when the two grooves are not aligned. This causes significant difficulties for the subsequent installation of corner brackets. Therefore, finding a way to create aligned grooves on the two reinforcing ribs of the aluminum alloy door and window frame is a technical problem that urgently needs to be solved by those skilled in the art.

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] As shown in Figures 1 and 2, this embodiment provides a grooving processing device for aluminum alloy windows, including a support platform 1 for supporting aluminum profile a, and a support platform 2 installed above the support platform 1, which can simultaneously support two reinforcing ribs b. The width of the support platform 2 is the same as the width between the two aluminum profiles a. A receiving groove 201 is provided on the support platform 2 corresponding to the position of each reinforcing rib b, and the two receiving grooves 201 are symmetrical to each other. The grooving processing device for aluminum alloy windows also includes a stamping knife 3 that moves up and down relative to the support platform 2. The two ends of the stamping knife 3 are cutting head parts and correspond to the positions of the two receiving grooves 201 respectively.

[0034] During use, the operator holds the aluminum alloy window frame and places the end to be slotted onto the support platform 1, ensuring the beveled edge of the aluminum profile a faces upwards. The frame position is then adjusted so that the slotted position on the reinforcing rib b aligns with the receiving groove 201. The slotted position on the reinforcing rib b can be pre-marked with a marker; aligning the mark with the receiving groove 201 achieves alignment. The dimensions of the support platform 1 are designed according to the specific length of the frame, ensuring the frame remains horizontal after the operator releases their grip. When the frame is horizontal, the bottom surface of the reinforcing rib b is in contact with the upper surface of the support platform 2, providing support for the reinforcing rib b. The stamping blade 3 is lowered by external force. 3. The groove to be cut on the reinforcing rib b is punched and slotted. Since the two receiving grooves 201 on the support platform 2 are symmetrical, the slots cut by the punching knife 3 on the two reinforcing ribs b are also aligned. After slotting, the waste material generated on the reinforcing rib b automatically falls into the receiving groove 201. During the contact between the punching knife 3 and the reinforcing rib b, the support platform 2 always supports the reinforcing rib b. After slotting is completed, the punching knife 3 is raised and reset by external force, and then the operator can remove the slotted frame. It should be noted that during the slotting process, the support platform 2 is in contact with the vertical surfaces of the two aluminum profiles a, which plays a horizontal limiting role on the aluminum profiles a, and avoids the frame from horizontally swaying in the direction perpendicular to the reinforcing rib b, thereby further ensuring that the slots cut on the two reinforcing ribs b are aligned.

[0035] As shown in Figures 1 and 2, the grooving device for aluminum alloy windows in this embodiment also includes a base 5, a support platform 1 fixedly installed on the base 5, and a mounting bracket 6 fixedly connected to the base 5; a hydraulic cylinder 7 is fixedly installed on the mounting bracket 6, and a tool holder 8 is slidably installed on the mounting bracket 6, with the telescopic end of the hydraulic cylinder 7 fixedly connected to the tool holder 8; a stamping knife 3 is installed on the tool holder 8; the hydraulic cylinder 7 drives the tool holder 8 to rise and fall, thereby driving the stamping knife 3 to rise and fall; specifically, when the hydraulic cylinder 7 extends, the tool holder 8 and the stamping knife 3 descend, and the stamping knife 3 grooves the reinforcing rib b; when the hydraulic cylinder 7 retracts, the tool holder 8 and the stamping knife 3 rise and reset.

[0036] Example 2

[0037] As shown in Figures 3 and 10, based on the above embodiments, the support platform 2 in this embodiment includes a fixed part 202 and two movable parts 203. The movable parts 203 are slidably mounted on the fixed part 202, and a receiving groove 201 is formed between the movable parts 203 and the fixed part 202. When the movable parts 203 slide on the fixed part 202, the length of the receiving groove 201 along the direction of the reinforcing rib b also changes synchronously. The two movable parts 203 are fixedly connected by a synchronous frame 4. The synchronous frame 4 consists of an upward-opening U-shaped part and two horizontal parts installed at the top of the U-shaped part. The two horizontal parts are divided into... The two moving parts 203 are fixedly connected to the corresponding moving part 203. The synchronous frame 4 can ensure that the two moving parts 203 move synchronously and the same distance, thereby ensuring that the length of the two receiving grooves 201 along the direction of the reinforcing rib b is consistent. In this embodiment, the stamping knife 3 can be disassembled and replaced from the knife holder 8. Different stamping knives 3 have different blade widths, so different width slots can be opened on the reinforcing rib to adapt to different models of connecting angle brackets. In this embodiment, the width of the receiving groove 201 along the direction of the reinforcing rib can be adjusted by adjusting the position of the moving part 203, thereby adapting to stamping knives 3 with different blade widths.

[0038] The two opposing surfaces of the receiving groove 201, which is composed of the moving part 203 and the fixed part 202, are vertical and parallel to each other. During the process of the stamping knife 3 slotting the reinforcing rib b, the waste generated by stamping will enter the receiving groove 201, and the stamping knife 3 will also partially enter the receiving groove 201 to ensure that the waste is completely separated from the reinforcing rib b. The two sides of the knife head will be in contact with the vertical surfaces of the moving part 203 and the fixed part 202.

[0039] In actual production, after slotting, the bottom of the reinforcing rib b will have some downward-extending burrs along the edge of the slot. These burrs are generated during the separation of the waste material punched off by the stamping knife 3 from the reinforcing rib b. Later, during the installation of the corner brackets, the brackets are inserted from the end face of aluminum profile a into the area between two aluminum profiles a. The burrs at the bottom edge of the slot near the end face of aluminum profile a will affect the smooth entry of the insert on the corner bracket into the slot, causing great inconvenience to the splicing and installation of the window. Therefore, after slotting, the operator usually needs to use a file to smooth the burrs. Since there are four slots on a window frame, the operator needs to smooth them four times, which undoubtedly greatly reduces production efficiency. Based on the above-mentioned actual situation, and combined with the movable structure of the moving part 203 in this embodiment, the operator can... The two moving parts 203 are then moved, i.e., the moving parts 203 are pushed, so that the length of the receiving groove 201 along the direction of the reinforcing rib b is shortened. That is, while keeping the frame position unchanged, the moving parts 203 move relative to the edge of the slot, thereby smoothing the burrs at the bottom of the slot near the end face of the aluminum profile a through the moving parts 203. After smoothing, the moving parts 203 are reset, and finally the frame is removed. This eliminates the need for a separate smoothing step, greatly improving the processing efficiency. As for how to control the moving parts 203 to move after slotting and to reset after smoothing the burrs at the bottom of the slot near the end face of the aluminum profile a, the simplest way is to install an electric telescopic rod for controlling the moving parts 203 on the mounting bracket 6. This is existing technology and will not be described in detail in this embodiment.

[0040] As shown in Figures 4, 9, and 11, in this embodiment, an elastic telescopic plate 9 is rotatably mounted on the synchronous frame 4. The elastic telescopic plate 9 remains in an inclined state throughout the entire processing. A lifting rod 10 is fixedly mounted on the bottom of the tool holder 8, and the bottom end of the lifting rod 10 is rotatably connected to the telescopic section of the elastic telescopic plate 9. A limiting block 11 corresponding to the position of the synchronous frame 4 is mounted on the mounting frame 6. As shown in Figure 11, a mushroom buckle 901 is fixedly mounted on the telescopic section of the elastic telescopic plate 9, and a corresponding... The mushroom buckle 901 is fitted with a rubber groove 902; after the mushroom buckle 901 enters the groove 902, the telescopic section of the elastic telescopic plate 9 cannot continue to move into its sleeve section, and the telescopic section of the elastic telescopic plate 9 can only separate the mushroom buckle 901 from the groove 902 under considerable external force; through the above structure, it is possible to achieve the effect that the moving part 203 and the fixed part 202 remain relatively stationary when the stamping knife 3 slots the reinforcing rib b, and the moving part 203 moves relative to the fixed part 202 during the rising and resetting process of the stamping knife 3.

[0041] Specifically, in the initial state, the stamping cutter 3 is at its highest point of stroke, the hydraulic cylinder 7 is in a retracted state, and the elastic telescopic plate 9 is also in a retracted state. The elastic telescopic plate 9 has its smallest tilt angle in this state, the synchronous frame 4 is furthest from the limiting block 11, and the length of the receiving groove 201 along the direction of the reinforcing rib b is the smallest. As the hydraulic cylinder 7 extends, the stamping cutter 3 and the lifting rod 10 descend synchronously. The lifting rod 10 drives the end of the telescopic section of the elastic telescopic plate 9 to descend, and the elastic telescopic plate 9 as a whole is subjected to the tension of the lifting rod 10. The elastic telescopic plate 9 also simultaneously applies tension to the synchronous frame 4. Since the moving part 203 installed on the synchronous frame 4 is not subject to external resistance at this time, it will move under the pull of the synchronous frame 4. As the synchronous frame 4 gradually approaches the limiting block 11, the length of the receiving groove 201 along the direction of the reinforcing rib b also gradually increases, and the inclination angle of the elastic telescopic plate 9 gradually increases until the synchronous frame 4 and the limiting block 11 are in contact. It should be noted that during the above process, the mushroom buckle 901 is always located in the buckle groove 902, and the elastic telescopic plate 9 will not extend. As the hydraulic cylinder 7 continues to extend, the tool holder 8 and the stamping knife 3 continue to descend. The stamping knife 3 begins to contact the reinforcing rib b and slots the reinforcing rib b. The lifting rod 10 will continue to descend with the tool holder 8, but the synchronous frame 4 will not continue to move under the limiting action of the limiting block 11, and the moving part 203 will also remain relatively stationary with the fixed part 202. The length of groove 201 along the direction of reinforcing rib b remains unchanged, and at this time, the length of groove 201 along the direction of reinforcing rib b matches the width of the cutting head of stamping knife 3; as the lifting rod 10 continues to descend, the elastic telescopic plate 9 continues to rotate, and its tilt angle continues to increase. The pulling force applied by the lifting rod 10 to the elastic telescopic plate 9 causes the mushroom buckle 901 to disengage from the buckle groove 902, and the elastic telescopic plate 9 extends as a whole until the hydraulic cylinder 7 stops extending. The knife holder 8, stamping knife 3, and lifting rod 10 stop descending, that is, the stamping knife 3 has finished slotting the reinforcing rib b. At this time, the cutting head of the stamping knife 3 is located in the receiving groove 201, and the waste material generated by slotting automatically falls into the bottom of the receiving groove 201; this is the final state. In the stopped state, the elastic telescopic plate 9 and the lifting rod 10 are as shown in Figure 9; then, the hydraulic cylinder 7 retracts and resets, and the knife holder 8, the stamping knife 3 and the lifting rod 10 rise synchronously. Since the cutting head of the stamping knife 3 is located in the receiving groove 201, the stamping knife 3 acts as a block for the moving part 203. The moving part 203 will not move relative to the fixed part 202, and the synchronous frame 4 will not translate. Therefore, the elastic telescopic plate 9 will reverse, the tilt angle of the elastic telescopic plate 9 will decrease, and the elastic telescopic plate 9 will retract as a whole until the mushroom buckle 901 re-enters the buckle groove 902. At this time, the cutting head of the stamping knife 3 also simultaneously disengages from the receiving groove 201, and the stamping knife 3 no longer acts as a block for the moving part 203.As the hydraulic cylinder 7 continues to retract, the tool holder 8, the stamping blade 3, and the lifting rod 10 continue to rise. The tilt angle of the elastic telescopic plate 9 continues to decrease, while the overall length of the elastic telescopic plate 9 remains unchanged. The elastic telescopic plate 9 pushes the synchronous frame 4 to separate from the limit block 11. The synchronous frame 4 synchronously pushes the moving part 203 and the fixed part 202 to move relative to each other. This continues until the stamping blade 3 returns to its highest point of travel, i.e., the initial state. During the relative movement between the moving part 203 and the fixed part 202, the burrs at the edge of the slot near the end face of the aluminum profile a are smoothed. Through the above working process, it can be seen that in this embodiment, the hydraulic cylinder 7, as a single power source, not only realizes the grooving action of the stamping blade 3 on the reinforcing rib b, but also completes the smoothing action of the moving part 203 on the edge of the slot. Moreover, the two processes cooperate with each other, eliminating the need for an additional power source for the moving part 203, thus saving design and manufacturing costs.

[0042] As shown in Figure 3, in this embodiment, the limiting block 11 horizontally penetrates the mounting frame 6 and slides with the mounting frame 6. An adjusting plate 12 is fixedly installed at one end of the limiting block 11, and an adjusting screw 13 that penetrates the adjusting plate 12 is rotatably installed on the mounting frame 6. By rotating the adjusting screw 13, the horizontal position of the adjusting plate 12 and the limiting block 11 can be adjusted, that is, the distance between the limiting block 11 and the synchronous frame 4 in the initial state can be adjusted. When the distance between the limiting block 11 and the synchronous frame 4 is smaller, the displacement of the synchronous frame 4 from the initial position to the position where it is in contact with the limiting block 11 is smaller, that is, the length of the receiving groove 201 along the direction of the reinforcing rib b is smaller. When the distance between the limiting block 11 and the synchronous frame 4 is larger, the displacement of the synchronous frame 4 from the initial position to the position where it is in contact with the limiting block 11 is larger, that is, the length of the receiving groove 201 along the direction of the reinforcing rib b is larger. Through the above structure, the length of the receiving groove 201 along the direction of the reinforcing rib b can be controlled to adapt to different models of stamping knives 3.

[0043] As shown in Figures 3, 5, and 7, in this embodiment, a first discharge trough 204 is vertically opened in the middle of the support platform 2, and the bottom surface of the receiving trough 201 is inclined, with the side of the bottom surface of the receiving trough 201 closer to the first discharge trough 204 being the lower side; a second discharge trough 101 is horizontally opened on the support platform 1, penetrating the support platform 1 and connected to the first discharge trough 204; since the bottom surface of the receiving trough 201 is inclined, the waste material falling off the reinforcing rib b will automatically slide into the first discharge trough 204 after falling into the receiving trough 201, and then fall from the first discharge trough 204 into the second discharge trough 101. The operator only needs to clean the second discharge trough 101 to clean up the waste material.

[0044] As shown in Figure 3, two baffles 14 are fixedly installed on the support platform 1 in this embodiment. The baffles 14 have notches that mate with the end of the aluminum profile a. The operator holds the frame of the aluminum alloy window and places the end to be slotted on the support platform 1, so that the bevel of the end of the aluminum profile a faces upward. Then, the position of the frame is adjusted so that the end of the aluminum profile a mates with the notch on the baffle 14. This ensures that the position to be slotted on the reinforcing rib b is aligned with the position of the receiving groove 201. Applying a horizontal external force towards the baffle 14 to the aluminum profile a or the reinforcing rib b will hold the frame against the baffle 14 as a whole, ensuring that the aluminum profile a and the reinforcing rib b will not move horizontally during the processing.

[0045] During actual processing, operators found that after the grooving was completed, as the moving part 203 moved relative to the fixed part 202, that is, during the process of the moving part 203 smoothing the burrs at the bottom edge of the slot near the end face of the aluminum profile a, the top edge of the moving part 203 came into contact with the burrs and generated an interaction force with the burrs. In some cases, the moving part 203 would push the reinforcing rib b and the aluminum profile a as a whole to move horizontally. That is, the moving part 203 would push the entire frame to move horizontally. Since the premise for the moving part 203 to smooth the slot is that the moving part 203 and the reinforcing rib b move relative to each other, the occurrence of the above situation undoubtedly affected the smoothing effect of the moving part 203 on the burrs at the bottom of the slot.

[0046] As shown in Figures 6 and 12, based on the above-mentioned problems, in this embodiment, a horizontal limiting rod 15 is rotatably installed on the support platform 1 at the position corresponding to each receiving slot 201. The limiting rod 15 is an elastic telescopic structure, and the end of the telescopic section of the limiting rod 15 is arc-shaped. A stop block 1501 that cooperates with the end of the telescopic section is fixedly installed on the inner wall of the sleeve section of the limiting rod 15 to limit the telescopic range of the limiting rod 15. The limiting rod 15 has a limiting state as shown in Figure 6 and an avoidance state as shown in Figure 8. In the limiting state, the end of the limiting rod 15 abuts against the end face of the groove of the reinforcing rib b. The groove of the reinforcing rib b is the groove opened on the reinforcing rib b by the stamping knife 3. In the avoidance state, the two limiting rods 15 are outside the coverage area of ​​the stamping knife 3. In the avoidance state, the two limiting rods 15 rotate in a direction away from the middle of the support table 2, and can enter the limiting state shown in Figure 6. It should be noted that the core innovation of the above design is that by limiting the groove of the reinforcing rib b, the overall limiting of the aluminum profile a is achieved, ensuring that the moving part 203 and the aluminum profile a can move relative to each other, thereby ensuring the smoothing effect of the bottom edge of the groove by the moving part 203.

[0047] Specifically, during the process of the stamping cutter 3 contacting the reinforcing rib b and slotting the reinforcing rib b, the two limiting rods 15 are in the avoidance state shown in Figure 8; after the slotting is completed, the stamping cutter 3 rises and disengages from the receiving groove 201, and the two limiting rods 15 are rotated in the direction of the arrow shown in Figure 8 by external force and enter the limiting state. The limiting rods 15 limit the slot of the reinforcing rib b, so that the reinforcing rib b and the aluminum profile a (i.e., the entire frame) will not be continuously pushed by the moving part 203, thereby causing relative displacement between the reinforcing rib b and the moving part 203. This ensures that the moving part 203 can smooth the burrs at the edge of the bottom of the slot near the end face of the aluminum profile a. It should be noted that during the process of the limiting rod 15 rotating from the avoidance state shown in Figure 8 to the limiting state shown in Figure 6, the end of its telescopic section first contacts the edge of the reinforcing rib b and shortens under the reaction force of the reinforcing rib b. As the limiting rod 15 continues to rotate, the end of the telescopic section of the limiting rod 15 enters the slot, and the limiting rod 15 returns to its elongated state. In summary, the limiting rod 15 of the telescopic structure can definitely be inserted into the slot on the reinforcing rib b during the rotation process.

[0048] During the above process, when the stamping knife 3 moves upward after slotting, once the stamping knife 3 disengages from the slot on the reinforcing rib b, that is, after the stamping knife 3 separates from the reinforcing rib b, the stamping knife 3 no longer acts as a horizontal obstruction to the reinforcing rib b. Therefore, before the limiting rod 15 rotates to the limiting state, the translation process of the moving part 203 may push the entire frame to move. In this embodiment, even if the above situation occurs, it does not hinder the realization of the smoothing function of the moving part 203, because as long as the limiting rod 15 can eventually rotate to the limiting state, there will inevitably be relative movement between the moving part 203 and the reinforcing rib b, and the moving part 203 will inevitably smooth the burrs at the edge of the slot near the end face of the aluminum profile a. In summary, the limiting rod 15 does not need to immediately enter the limiting state at the moment the stamping knife 3 separates from the reinforcing rib b, as long as the limiting rod 15 can eventually rotate to the limiting state.

[0049] As shown in Figure 6, a rotating shaft 16, fixedly connected to each limiting rod 15, is rotatably installed on the support platform 1 at the position corresponding to each limiting rod 15. An adjusting gear 17 is fixedly installed on the rotating shaft 16. A sliding plate 18 is slidably installed on the support platform 1, and a rack 19, meshing with each adjusting gear 17, is fixedly installed on the sliding plate 18 at the position corresponding to each adjusting gear 17. When the sliding plate 18 is moved by external force, the sliding plate 18 will drive the two racks 19 to move synchronously. The racks 19 will drive the adjusting gears 17 meshing with them to rotate. The adjusting gears 17 will drive the rotating shaft 16 and the limiting rod 15 to rotate synchronously. That is, the switching between the two states of the limiting rod 15 can be achieved by controlling the sliding plate 18. An electric telescopic rod for controlling the sliding plate 18 can be installed on the support platform 1. This is the prior art, and will not be elaborated on in this embodiment.

[0050] Referring to Figure 6, it should be noted that in this embodiment, the sliding range of the sliding plate 18 is limited, and due to the presence of the blocking block 1501, the degree of retraction of the limiting rod 15 is also limited. The limiting rod 15 will not rotate clockwise continuously under the push of the reinforcing rib b. After the limiting rod 15 rotates to the limiting state, it will not continue to rotate clockwise. That is, the limiting rod 15 can remain in the limiting state to block and limit the reinforcing rib b.

[0051] As shown in Figures 4 and 6, in this embodiment, a pressure plate 20 is fixedly installed on the support platform 1, and a return spring 21 is fixedly connected between the pressure plate 20 and the sliding plate 18; a horizontal push rod 22 is fixedly installed on the sliding plate 18, and a roller 23 is installed at the end of the push rod 22; a guide plate 24 is vertically fixedly installed on the tool holder 8 corresponding to the position of the roller 23, and the edge of the guide plate 24 facing the roller 23 includes a vertical section and an inclined section, with the vertical section located above the inclined section.

[0052] In this embodiment, before the frame is placed on the support platform 1, the initial state of the limiting rod 15 is the limiting state. At this time, due to the obstruction of the limiting rod 15, the operator cannot place the frame on the support platform 1 from top to bottom. The frame can only be placed on the support platform 1 by horizontal insertion until the tip of the aluminum profile a is in contact with the notch on the baffle 14. During the insertion process, the reinforcing rib b will come into contact with the limiting rod 15 and push the limiting rod 15 to rotate a small distance from the limiting state to the avoidance state. The end of the telescopic section of the limiting rod 15 will eventually come into contact with the edge of the reinforcing rib b, and the return spring 21 will be compressed a small distance. As the tool holder 8 drives the guide plate 24 to descend, the inclined section of the guide plate 24 first contacts the roller 23 and pushes the roller 23 and the push rod 22 to move horizontally. The push rod 22 drives the sliding plate 18 to move horizontally. The sliding plate 18 further compresses the return spring 21, and at the same time, the limiting rod 15 rotates to the avoidance state. The guide plate 24 is in a state of avoidance. Then, the vertical section of the guide plate 24 contacts the roller 23, and the stamping knife 3 also contacts the reinforcing rib b and slots it. The limiting rod 15 always remains in the avoidance state. After the slotting is completed, the knife holder 8 drives the guide plate 24 to rise and reset. When the inclined section of the guide plate 24 contacts the roller 23, the return force of the reset spring 21 causes the sliding plate 18 to move and reset. The limiting rod 15 also gradually rotates from the avoidance state to the limiting state. Finally, the limiting rod 15 rotates to the state shown in Figures 5 and 6, that is, the state of blocking and limiting the reinforcing rib b, so that the moving part 203 can smoothly grind the burrs at the edge of the bottom of the slot near the end face of the aluminum profile a. It should be noted that in this embodiment, due to the presence of the baffle 14, the frame will not move vertically, that is, it will not be lifted under the action of external force, which further ensures the grinding effect of the moving part 203 on the burrs during the horizontal movement of the moving part 203 relative to the reinforcing rib b.

[0053] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
