[0001] The invention relates to the technical field of door and window cutting, and in particular to a door and window corner cutting device. Background Art

[0002] In order to make the doors and windows fit together during installation, the corners of the doors and windows usually need to be cut into 45° with a cutting machine so that they can be assembled.

[0003] In the process of cutting the edges and corners of aluminum alloy doors and windows, due to human negligence, the cutting machine is used for a long time without replacing the cutting machine saw blade in time, resulting in excessive aging of the tool.

[0004] Therefore, according to the above-mentioned problems, a door and window corner cutting device is designed. Summary of the invention

[0010] In one of the embodiments, it also includes a pushing block, which is fixedly connected to the latch tooth. The sliding frame is connected to a limit block symmetrically arranged along the sliding frame.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0033] Embodiment 1:

[0034] A door and window corner cutting device, such as Figure 1-Figure 5As shown, it includes a base 101, a symmetrically arranged placement frame 102 is fixedly connected to the right side of the top of the base 101, the angle between the symmetrically arranged placement frames 102 is 45°, which is used to align the angles of the door and window frames, a symmetrically installed cylinder 103 is fixedly connected to the lower part of the base 101, a sliding frame 104 is slidably connected to the right side of the top of the base 101, the sliding frame 104 is slidably connected to the cylinder 103, a blocking rod is arranged on the top of the sliding frame 104, which is used to limit the lifting angle of the rotating frame 105, the rotating frame 105 is rotatably connected to the upper part of the sliding frame 104, a cutting machine 106 is fixedly installed on the left side of the rotating frame 105, a fixing ring 107 is fixedly connected to the rotating shaft of the rotating frame 105 close to the sliding frame 104, a symmetrically arranged first telescopic rod 109 is fixedly connected to the right side of the sliding frame 104, the symmetrically arranged first telescopic rod 109 is fixedly connected to a latch tooth 108, the limiting tooth of the latch tooth 108 is inclined on one side, and the latch tooth 108 is inclined to the The first limit frame 110 is engaged and cooperates to limit the sliding frame 104. The first limit frame 110 is rotatably connected to the right side of the top of the base 101. The left side of the first limit frame 110 and the right side of the top of the base 101 are respectively fixedly installed with electromagnets 111. The front side of the top of the rotating frame 105 is fixedly connected to a contact switch 112. A side of the rotating frame 105 adjacent to the contact switch 112 is slidably connected with a striker 113. The striker 113 is located between the contact switches 112. The contact switch 112 is electrically connected to the input end of the control module through wires, and the output end of the control module is electrically connected to the cylinder 103 through wires. The contact switch 112 is electrically connected to the input end of the control module through wires, and the output end of the control module is electrically connected to the electromagnet 111 through wires. A first spring 114 is fixedly connected between the striker 113 and the rotating frame 105, and a second telescopic rod 115 is rotatably connected to the left side of the top of the sliding frame 104 and the middle of the lower part of the rotating frame 105.

[0035] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, it also includes a pushing block 201, which is fixedly connected to the top left side of the latch tooth 108. The upper part of the sliding frame 104 is rotatably connected to a symmetrically arranged limit block 202. The symmetrically arranged limit block 202 is movably connected to the pushing block 201. A second spring 203 is fixedly connected between the sliding frame 104 and the cylinder 103.

[0036] When it is necessary to cut the corners of the door and window frames, first, place the door and window frames to be cut in the placement frame 102, then start the cylinder 103, the cylinder 103 drives the second spring 203 to descend, and the second spring 203 drives the sliding frame 104, the rotating frame 105, the cutting machine 106, the fixing ring 107, the latch 108, the first telescopic rod 109, the contact switch 112, the striker 113, the first spring 114, the second telescopic rod 115, the pushing block 201 and the limit block 202 to descend synchronously. During the descent of the movable cutting machine 106, the cutting machine 106 contacts the door and window frames and cuts the corners of the door and window frames. During the cutting process, the vibration generated by the cutting machine 106 causes the striker 113 to slide up and down continuously, and the first spring 114 is constantly deformed and reset. By selecting the first spring 114 with an adaptive elastic coefficient, when the saw blade loss of the cutting machine 106 is small, the vibration generated by the cutting machine 106 is sufficient to be offset by the first spring 114, so that the striker 113 does not contact the contact switch 112, allowing the cutting machine 106 to complete normal cutting work;

[0037] When the saw blade of the cutting machine 106 is worn too much, the wear makes the saw blade edge no longer sharp and becomes uneven, which will cause the contact surface to become larger during cutting, increase the cutting resistance, and thus cause vibration. At the same time, the worn saw blade is more likely to deform due to frictional heat during the cutting process. Thermal deformation will make the center of the saw blade unbalanced during rotation, further aggravating the vibration during cutting. At this time, the elastic force of the first spring 114 is not enough to offset the vibration caused by the cutting machine 106, so that the striker 113 contacts the contact switch 112 during the up and down sliding process, and the contact switch 112 sends out an electrical signal. After receiving the electrical signal, the control module controls the electromagnet 111 to be energized and the cylinder 103 to stop. The electromagnet 111 is energized, and the electromagnets 111 are instantly adsorbed, thereby making the first limit The frame 110 rotates counterclockwise, pushing the latch tooth 108 to move to the left until the first limit frame 110 is stuck in the latch tooth 108, and the first telescopic rod 109 is deformed and compressed by the force. The latch tooth 108 cannot move downward after being limited, so that the sliding frame 104 and the corresponding components arranged on the sliding frame 104 stop moving downward. When the latch tooth 108 moves to the left, it drives the pushing block 201 to move to the left, and then drives the limit block 202 to rotate counterclockwise, so that the limit block 202 is disengaged from the fixing ring 107 and no longer locks the fixing ring 107. The second telescopic rod 115 is reset and stretched, thereby pushing the rotating frame 105, the cutting machine 106, the electromagnet 111, the contact switch 112, the striker 113, and the first spring 114 to rotate clockwise. The cylinder 103 stops moving at a certain angle and is lifted upward, so that the cutting machine 106 is separated from the door and window frame and leaves the cutting position. At the same time, the cylinder 103 stops moving. Since the cylinder 103 receives the command from the control module, it takes time to react in the whole process from when the cylinder 103 stops to when the cylinder 103 stops, resulting in a short delay in the cylinder 103 stopping. After the sliding frame 104 is stopped by the first limit frame 110, there is still some time to shrink. As a result, the tension generated by the shrinkage of the cylinder 103 is transmitted to the first limit frame 110 through the sliding frame 104. The first limit frame 110 is easily deformed by the tension of the cylinder 103. Therefore, when the sliding frame 104 is blocked by the first limit frame 110 and stops descending, during the delayed stop of the cylinder 103, The cylinder 103 contracts, thereby squeezing the second spring 203. The second spring 203 is compressed, thereby absorbing the force of the cylinder 103 contraction, allowing the cylinder 103 to have enough time and distance to stop running. After the saw blade is replaced, the electromagnet 111 and the first limit frame 110 are driven to reset, and then the rotating frame 105 is pressed to reset the rotating frame 105. The second telescopic rod 115 is compressed. When the first limit frame 110 is disengaged from the latch tooth 108, the first telescopic rod 109 is reset, thereby driving the latch tooth 108 to move to the right. The latch tooth 108 pulls the push block 201 to move to the right, and then drives the limit block 202 to rotate clockwise and re-engage the fixing ring 107 to lock the rotating frame 105 and complete the reset. In summary,Through the cooperation between the sliding frame 104 and the first limiting frame 110, when the saw blade of the cutting machine 106 is worn too much and causes severe vibration to the door and window frame, the cutting machine 106 is automatically disengaged from the cutting position to prevent the excessive vibration caused by cutting from causing problems in the cutting quality of the door and window frame, and at the same time, it is prevented that the saw blade cannot withstand the severe vibration during cutting, causing fragments to be splashed, causing safety hazards.

[0038] Embodiment 2:

[0039] On the basis of Example 1, Figure 1 and 9 As shown, it also includes a second limit frame 301, which is slidably connected to the left side of the top of the base 101. A limit tooth is opened on the lower right side of the second limit frame 301, which is used to lock the door and window frames to prevent them from jumping when cutting. A limit rod 302 is slidably connected to the middle of the top of the base 101, and a guide frame 303 is fixedly connected to the left side of the sliding frame 104. A third spring 304 is fixedly connected between the base 101 and the limit rod 302. A roller 305 is rotatably connected to the right side of the limit rod 302, and the roller 305 is in contact with the guide frame 303.

[0040] In order to avoid the vibration of the door and window frames when cutting the corners of the door and window frames, which may cause the cutting machine 106 to deviate from the cutting position, the specific operation is as follows: before placing the door and window frames on the placement frame 102, manually lift the second limit frame 301, then place the door and window frames in the placement frame 102, and perform the cutting operation, then release the second limit frame 301, and the second limit frame 301 will drop due to the influence of gravity, pressing the door and window frames for limiting. When the sliding frame 104 drives the cutting machine 106 to descend to cut the door and window frames, the sliding frame 104 descends, thereby driving the guide frame 303 to descend, and then driving the guide frame 303 to squeeze the roller 305 and the limit rod 302 to move to the left, and the third spring 304 is deformed under force, so that the guide frame 303 pushes the limit rod 302 to lock. The second limit frame 301 is inserted into the limiting teeth of the second limit frame 301, locking the second limit frame 301 to prevent the door and window frame from moving during cutting. When the door and window frame is cut, as the sliding frame 104 rises, the sliding frame 104 drives the guide frame 303 to move upward and reset. When the guide frame 303 is disengaged from the roller 305, the third spring 304 is deformed and reset, thereby driving the limiting rod 302 and the roller 305 to move to the right and reset. The limiting rod 302 is disengaged from the limiting teeth of the second limit frame 301, unlocking it, and then the door and window frame after cutting is taken away. In summary, through the cooperation between the second limit frame 301 and the limiting rod 302, the door and window frame is automatically limited and locked during cutting, thereby improving the stability and accuracy of the cutting machine in cutting the door and window frame.

[0041] like Figure 1 and 10 As shown, a calibration frame 401 is also included. The calibration frame 401 is fixedly connected to the lower left side of the sliding frame 104. The calibration frame 401 is in the shape of a triangular prism and is used to calibrate the angle of the door and window frames.

[0042] In order to avoid the inability to grasp the cutting angle when cutting the corners of the door and window frames, resulting in deviation in the cutting angle and affecting the cutting quality, the specific operations are as follows: when the door and window frames are placed on the placement frame 102, the door and window frames are pushed closer to the calibration frame 401 until they are fitted to the position of the calibration frame 401 to complete the calibration of the door and window frames. Then, when the sliding frame 104 drives the cutting machine 106 to descend, the sliding frame 104 drives the calibration frame 401 to move downward synchronously, and the calibration frame 401 is separated from the door and window frames, so that the cutting machine 106 will The corners of the door and window frames are cut. When the cutting machine 106 bends and completes the cutting, as the sliding frame 104 rises and resets, the sliding frame 104 drives the calibration frame 401 to rise to the initial position and completes the reset. In summary, through the cooperation between the sliding frame 104 and the calibration frame 401, the position of the door and window frames is calibrated to prevent the angle from being unable to be measured when the cutting machine 106 cuts the corners of the door and window frames, resulting in angle deviation of the door and window frames after cutting, causing angle deviation when the door and window frames are aligned and installed with each other.

[0043] like Figure 1 and Fig.11 As shown, a measuring frame 501 is also included, and the measuring frame 501 is fixedly connected to the outer side of the placement frame 102.

[0044] In order to avoid the corners of the door and window frames being cut at different lengths due to the inability to know the sizes of each door and window frame before cutting, the specific operation is as follows: when the corners of the door and window frames need to be cut, the length of the door and window frames can be known by observing the measuring frame 501 outside the placement frame 102, thereby avoiding the occurrence of different lengths during cutting. In summary, through the cooperation between the placement frame 102 and the measuring frame 501, the length of the door and window frames that need to be cut can be known through the measurement of the measuring frame 501, thereby avoiding the tedious process of measuring with the help of other tools and improving work efficiency.

[0045] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
