Description

Technical Field

[0001] The utility model relates to the field of profile cutting, in particular to a profile cutting device for doors and windows. Background Technique

[0002] The statements in this part only provide background technical information related to the utility model, and do not necessarily constitute prior art.

[0003] When profiles are in use, due to different installation positions and stress conditions, the profiles need to be cut at different angles. And when the cutting angles of the profiles are different, it will also affect the tightness and stability during the connection of the profiles. Therefore, it is necessary to ensure that the angles between two profiles are complementary. Thus, how to effectively cut the profiles so that they can be tightly connected is a problem to be solved.

[0004] For existing profile cutting tools, they are generally divided into two types: one is to push the profile to move, so that the cutting tool cuts the profile. However, this method is inconvenient for cutting long profiles, and errors will occur during the cutting process. Therefore, most use the cutting method of fixing the profile and moving the cutting tool to cut the profile. However, this method requires the cutting tool to move along the guide rail to achieve the cutting of the profile. But most of the guide rails are located below the cutting tool, and waste chips will fall on the guide rail during the cutting of the profile, thus affecting the movement of the cutting tool on the guide rail. Therefore, how to avoid waste chips falling on the guide rail during profile cutting and thus affecting the operation of the tool is a problem to be solved.

[0005] For a profile, due to different installation and use environments of the profile, the cutting angles required during profile cutting are different. And the cutting angles of the profile usually have two types: adjusting the cutting angle of the cutting tool and adjusting the angle of the profile. Due to reasons such as the long length of the profile, usually the angle of the cutting tool is adjusted to complete the cutting of the profile. And the adjustment of the cutting tool angle is divided into two types: manual or mechanical adjustment. And the accuracy of the manually adjusted cutting tool is not high. Therefore, how to make the cutting tool be mechanically adjusted and achieve good and precise adjustment is a problem to be solved.

[0006] During the use of the profile, the required length of the profile is fixed. Therefore, it is necessary to cut both ends of the profile so that the profile is cut into the required length. However, the cutting angles required at both ends of the same profile are different. Therefore, it is necessary to perform tool changing processing on the cutting tool, that is, adjust the angle of the cutting tool to cut the profile. Thus, how to facilitate the tool changing processing of the cutting tool so that both ends of the profile can be effectively cut is a problem to be solved.

[0007] Since a large number of the same profiles need to be processed during production, and the profiles to be cut will shake when the other end of the profile is cut, errors will occur at the cutting part. Therefore, how to prevent the cut profiles from shaking so that the profiles can be cut well is a problem to be solved.

[0008] For the profile cutting process, both the cut profiles and the waste generated during the profile cutting process need to be removed. Therefore, how to facilitate the removal of profiles and waste and reduce the pollution of the environment caused by waste is a problem to be solved. How to facilitate the collection of profiles and prevent the profiles from being randomly distributed after cutting. Utility Model Content

[0035] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0036] The present utility model relates to a window and door profile cutting device, and its main structure includes a frame 1, a driving device 2, a cutting device 3, and a fixing device 4. The frame 1 provides a supporting and protecting function for the entire device, enabling each component to be sequentially installed on the frame 1 for use. Moreover, the housing used for enclosing on the frame 1 also provides a supporting function for the window and door profiles during the cutting process, preventing the window and door profiles from vibrating after contacting the cutting device 3, thereby affecting the accuracy of the profiles.

[0037] The driving device 2 includes an X-axis movement device 5, a Y-axis movement device 6, and a Z-axis movement device 7, which respectively control the movement of the cutting device 3 in the X-axis, Y-axis, and Z-axis directions, enabling the cutting device 3 to better cut the window and door profiles. Among them, the X-axis movement device 5 is slidably connected to the top of the frame 1, the Y-axis movement device 6 is slidably connected to the X-axis movement device 5, the Z-axis movement device 7 is slidably connected to the Y-axis movement device 6, and the cutting device 3 is arranged on the Z-axis movement device 7, enabling the cutting device 3 to move in a three-dimensional space.

[0038] The X-axis moving device 5 includes an X-axis moving motor 8 and an X-axis moving member 9 fixedly connected to the X-axis moving motor 8. Among them, guide rails 10 connected to the X-axis moving member 9 are provided on both sides of the top of the frame 1, so that the X-axis moving member 9 and the frame 1 can move relative to each other. In order to enable the X-axis moving device 5 to be controlled to move by a control terminal, a rack 11 is provided on one side of the top of the frame 1, and a gear 12 adapted to the rack 11 is provided on the output shaft of the X-axis moving motor 8. The rack 11 and the gear 12 mesh with each other, so that when the X-axis moving motor 8 rotates, it drives the X-axis moving member 9 to move along the X-axis. And the X-axis moving motor 8 is connected to the control terminal. The X-axis moving motor 8 is arranged at one end of the X-axis moving member 9, and the rack 11 is provided below the X-axis moving motor 8. By controlling the number of rotation turns of the X-axis moving motor 8, the movement of the X-axis moving device 5 in the X-axis direction is realized. Since the rack 11 provided on the frame 1 has a certain length, the X-axis moving motor 8 can rotate within a certain range and can rotate forward and backward.

[0039] The Y-axis moving device 6 includes a Y-axis moving member 13 and a Y-axis moving motor 14 fixedly connected to the X-axis moving member 9. Since the Y-axis moving device 6 controls the cutting device 3 to move in the Y-axis direction and also needs to ensure that it can move in the X-axis direction during the movement, the Y-axis moving member 13 is connected to the X-axis moving member 9, so that the Y-axis moving member 13 completes the Y-direction movement on the X-axis moving member 9 to meet the movement in the X-axis and Y-axis directions. Slide rails 15 are provided on both sides of the X-axis moving member 9, and the X-axis moving member 9 and the Y-axis moving member 13 are connected through the slide rails 15, so that the Y-axis moving member 13 can move on the X-axis moving member 9. However, in order to control the movement of the Y-axis moving member 13, a Y-direction transmission rod 16 is provided on the X-axis moving member 9, and the Y-direction transmission rod 16 is also connected to the Y-axis moving member 13. By controlling the rotation of the Y-direction transmission rod 16, the normal movement of the Y-axis moving member 13 is ensured. One end of the Y-direction transmission rod 16 is connected to the Y-axis moving motor 14 fixedly arranged on the X-axis moving member 9, so that the control terminal controls the forward and reverse rotation of the Y-axis moving motor 14, thereby controlling the rotation of the Y-direction transmission rod 16, and sequentially realizing the Y-direction movement of the Y-axis moving member 13. The Y-direction transmission rod 16 and the Y-axis moving member 13 here adopt the screw-nut transmission technology to realize the Y-direction movement, that is, the Y-direction transmission rod 16 is a screw, and a nut is provided at the connecting part of the Y-axis moving member 13 and the Y-direction transmission rod 16. And the forward and reverse rotation of the Y-axis moving motor 14 also has a range limit to prevent excessive rotation from causing the Y-axis moving member 13 to collide with both ends of the X-axis moving member 9.

[0040] The Z-axis motion device 7 includes a Z-axis moving member 17 and a Z-axis motion motor 18 fixedly connected to the Y-axis moving member 13, and the connection mode of the Z-axis motion device 7 and the Y-axis motion device 6 is the same as that of the Y-axis motion device 6 and the X-axis motion device 5. That is, tracks 19 are provided on both sides of the Y-axis moving member 13, and the Y-axis moving member 13 and the Z-axis moving member 17 are connected through the tracks 19, so that the Z-axis moving member 17 can move on the Y-axis moving member 13. However, in order to control the movement of the Z-axis moving member 17, a Z-direction transmission rod 20 is provided on the Y-axis moving member 13, and the Z-direction transmission rod 20 is also connected to the Z-axis moving member 17. By controlling the rotation of the Z-direction transmission rod 20, the normal movement of the Z-axis moving member 17 is ensured. One end of the Z-direction transmission rod 20 is also connected to the Z-axis motion motor 18 fixedly arranged on the Y-axis moving member 13, so that the control terminal controls the forward and reverse rotation of the Z-axis motion motor 18, thereby controlling the rotation of the Z-direction transmission rod 20, and sequentially realizing the movement of the Z-axis moving member 17 in the Z-axis direction. The Z-direction transmission rod 20 and the Y-axis moving member 13 here adopt the screw and nut transmission technology to achieve the Z-direction movement. That is, the Z-direction transmission rod 20 is a screw, and a nut is arranged at the connection part of the Z-axis moving member 17 and the Z-direction transmission rod 20. And the forward and reverse rotation of the Z-axis motion motor 18 also has a range limit to prevent excessive rotation so that the Z-axis moving member 17 collides with both ends of the Y-axis moving member 13. A cutting device 3 is also provided on the Z-axis moving member 17. The function of the cutting device 3 is to cut the door and window profiles. However, waste chips will be generated during the cutting process of the cutting device 3, which will affect the transmission accuracy of the screw and nut and the gear and rack. Therefore, the cutting device 3 on the Z-axis moving member 17 is located below the entire driving device 2, that is, the cutting device 3 is provided at the bottom of the Z-axis moving member 17, so as to reduce the situation where waste chips fall on the screw and nut and the gear and rack during the cutting process. Ensure the normal operation of the driving device 2.

[0041] Since the cutting device 3 is located at the bottom of the Z-axis moving member 17, during the entire cutting process, the feed inlet 26 of the door and window profiles should be approximately at the same height as the cutting device 3, so that the cutting device 3 can easily cut the door and window profiles. The cutting device 3 includes a cutting tool 21, a control member 22, and a rotating member 23. The control member 22 is arranged on the Z-axis moving member 17 and fixedly connected to the Z-axis moving member 17, so that the Z-axis moving member 17 can drive its movement. The rotating member 23 and the cutting tool 21 are also arranged on the Z-axis moving member 17, and the cutting tool 21 is connected to the rotating member 23, so that the rotating member 23 notifies the rotation angle of the cutting tool 21, thereby cutting the door and window profiles at different angles. Here, the specific structure of the rotating member 23 is a gear-rack transmission mechanism, and the control member 22 is a telescopic rod. The telescopic rod is fixedly connected to the rack 11 structure on the rotating member 23. The rotation of the gear 12 is realized through the telescopic movement of the telescopic rod, and then the rotation of the cutting tool 21 is realized. And by controlling the telescopic length of the telescopic rod, the adjustment of different cutting angles of the cutting tool 21 is realized. The cutting tool 21 here includes a tool, a motor, etc. The motor drives the tool to rotate, thereby realizing cutting, etc. The motor is connected to the rotating member 23, so that when the rotating member 23 rotates, it can drive the motor and the tool to rotate at a certain angle together. And the motor here only controls the rotation of the tool, that is, when the power is on, the tool rotates to cut the door and window profiles, and when the power is off, it stops moving. For the chamfering of door and window profiles with some special angles, only the telescopic length of the control member 22 (telescopic rod) needs to be controlled, and the cutting angle of the cutting tool 21 is controlled by the length of the telescopic rod extending out.

[0042] For the cutting of door and window profiles, if one end of the door and window profile needs to be cut, the door and window profile needs to be aligned so that the machine can perform precise cutting during the cutting process. Therefore, a limiting device 28 is provided at the bottom of the X-axis moving part 9. The limiting device 28 plays a limiting role on one end of the door and window profile. That is, in industrial cutting, there are absolute coordinate systems and relative coordinate systems. The position where the limiting device 28 contacts the door and window profile is an X-axis in the relative coordinate system for the cutting tool 21, so that the cutting length of the door and window profile is controlled. The limiting device 28 here includes a telescopic motor 29 and a limiting member 30. The telescopic motor 29 is fixedly connected to the bottom of the X-axis moving part 9, so that the telescopic motor 29 will not move in the Y-axis and Z-axis directions, and the limiting member 30 plays a limiting role on the door and window profile at a certain height. The setting of the telescopic motor 29 is that when the door and window profile is against it and needs to be cut, if the limiting member 30 is not separated from the door and window profile, it will cause the door and window profile to rub against the limiting member 30, etc., and then cause the door and window profile to be displaced. Therefore, when cutting is required, the telescopic motor 29 moves to separate the limiting member 30 from the door and window profile, and then moves in the X-axis direction. And during the entire cutting process of the door and window profile, not all cutting processes require the limiting device 28 to align it. Therefore, when the limiting device 28 is not needed for alignment, the contact between the limiting device 28 and the door and window profile should be avoided at this time, and the tool change process of the cutting tool 21 can still be completed. Therefore, there should be a certain distance between the limiting device 28 and the cutting tool 21, so that the limiting device 28 can complete the tool change process of the cutting tool 21 without interfering with the cutting process of the door and window profile.

[0043] During the cutting process of door and window profiles, it is necessary to fix the door and window profiles to prevent the influence of the cutting tool 21 on the position of the door and window profiles during the cutting process. Therefore, a fixing device 4 is also provided on the machine frame 1. The fixing device 4 clamps the door and window profiles. Therefore, the position where the fixing device 4 is set should be approximately the same as the height of the limiting device 28, so that one end of the door and window profiles can still contact the limiting device 28 while being clamped by the fixing device 4. And in order to enable the door and window profiles to be placed and clamped by the fixing device 4, the machine frame 1 is also provided with a feeding port 26 on one side of the fixing device 4, so that the door and window profiles can be clamped. The fixing device 4 includes a fixing plate 24 and a driving member 25. The output shaft of the driving member 25 is connected to the fixing plate 24, and by moving the output shaft up and down, the fixing plate 24 is driven to move up and down, thereby playing a clamping role on the door and window profiles. The driving member 25 is fixedly connected to the machine frame 1 here, providing support for the clamping of the door and window profiles. The top of the fixing plate 24 is also provided with a limiting rod 27, and the limiting rod 27 penetrates the machine frame 1, so that the fixing plate 24 can be stably limited during limiting, preventing the occurrence of situations such as deviation. That is, preventing the deviation of the fixing plate 24 during the clamping process due to the presence of door and window profiles on one side and the absence on the other side. The limiting member 30 enables the fixing plate 24 to move down stably and perform clamping. The machine frame 1 on the opposite side of the feeding port 26 also plays a role in limiting and supporting the door and window profiles during the cutting process of the door and window profiles. That is, when the initial cutting of the door and window profiles is completed, the door and window profiles continue to penetrate until they contact the machine frame 1, and then the cutting tool 21 cuts the door and window profiles. However, there is friction between the door and window profiles and the machine frame 1, so that the cutting tool 21 will not shake due to the excessive length of the door and window profiles during cutting, enabling the door and window profiles to be cut stably.

[0044] There is a collection port 31 at the bottom of the machine frame 1, that is, the waste materials cut by the cutting tool 21 and the door and window profiles fall out from this port together. The periphery of the collection port 31 is inclined, so that the waste materials can be discharged through the collection port 31, preventing the accumulation of waste materials.

[0045] This device controls the movements of the X-axis movement motor 8, Y-axis movement motor 14, Z-axis movement motor 18, control member 22, driving member 25, and telescopic motor 29 respectively through a control terminal, so that the X-axis movement motor 8, Y-axis movement motor 14, Z-axis movement motor 18, control member 22, driving member 25, telescopic motor 29, etc. can move in sequence. The control terminal uses PLC technology to control the movements of the above-mentioned drivers.

[0046] Detailed description of the usage method:

[0047] When this device is in use, it is first debugged so that the cutting tool 21 can precisely cut the door and window profiles. Then, the X-axis moving device 5 is moved to one end until it can no longer move. At this time, the limiting device 28 on the X-axis moving device 5 can abut against one end of the door and window profile, so that the door and window profile entering from the feed port 26 is limited. Then, the control terminal is used to control the movement of the telescopic motor 29 to separate the limiting member 30 from the door and window profile. After separation, the X-axis moving device 5 is moved, and at the same time, the control member 22 controls the cutting tool 21 to rotate so that the cutting tool 21 rotates to a specified angle. Then, the Y-axis moving device 6 and the Z-axis moving device 7 are respectively controlled by the control terminal so that the cutting tool 21 cuts the door and window profile. After the door and window profile is cut once, the cutting tool 21 is separated from the door and window profile. Then, the Z-axis moving device 7 and the Y-axis moving device 6 are sequentially moved so that the cutting tool 21 can perform tool change processing, that is, to prevent the cutting tool 21 from contacting the door and window profile when rotating the angle. When the cutting angle change of the cutting tool 21 is completed, then the Z-axis moving device 7 and the Y-axis moving device 6 are respectively moved to cut the door and window profile. However, while the cutting tool 21 is changing the tool, the door and window profile retracts inward from the feed port 26, so that one end of the door and window profile abuts against the machine frame 1, thereby preventing the occurrence of situations such as offset during the cutting of the door and window profile. After the door and window profile is cut, it will fall downward, and then it will fall out and be collected through the collection port 31 at the bottom of the machine frame 1.

[0048] In summary, this device can cut the door and window profiles. And because there is a rotating member 23 between the cutting tool 21 and the control member 22, the rotation angle of the cutting tool 21 is converted into a linear motion, making the control of the cutting tool 21 angle more precise. The X-axis moving device 5, Y-axis moving device 6, and Z-axis moving device 7 of this device are all located above the cutting tool 21, avoiding the waste chips generated during the cutting process of the cutting tool 21 from falling onto this device, thereby affecting the transmission accuracy of the cutting tool 21. There is also a fixing device 4 on the machine frame 1 of this device, so that the door and window profiles are clamped during the cutting process, preventing the contact between the door and window profiles and the cutting tool 21 during cutting, thereby affecting the cutting accuracy. And this device can perform effective tool change processing when the cutting angles at both ends of the profile need to be different through three-axis movement, preventing the influence on the door and window profiles during the tool change process. There is a collection port 31 at the bottom of the machine frame 1 of this device, so that the waste materials and the cut door and window profiles both fall out through this place, making the profiles easy to collect, and the collection of cutting waste chips can effectively prevent the pollution of the surrounding environment caused by the cutting waste chips.
