Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy doors and windows, specifically to an aluminum alloy door and window profile cutting device. Background Technology

[0002] Aluminum alloy doors and windows are a common type of doors and windows in modern buildings. They use aluminum alloy profiles as the main frame material and have many advantages such as light weight, high strength, corrosion resistance, beauty and durability. These doors and windows usually consist of multiple components. Among them, the atrium is a horizontal or vertical profile that connects the window frame and the window sash or separates multiple window sashes. Its main function is to enhance the overall stability of the door and window, and at the same time, it can also divide different window pane styles according to design requirements, making the structure of the door and window more reasonable and beautiful.

[0003] In the manufacturing process of aluminum alloy doors and windows, the atrium, as an important structural component, needs to be precisely cut according to the specific door and window dimensions and design requirements. The length and cutting angle of the atrium directly affect its assembly accuracy with the window frame and sash, which in turn affects the sealing performance, structural stability and appearance quality of the entire door and window.

[0004] Currently, in the aluminum alloy door and window manufacturing industry, cold saw cutting machines are mostly used when cutting atriums. However, the cutting table of existing cold saw cutting machines is relatively narrow. When cutting a long atrium, the part of the atrium that extends beyond the table lacks sufficient support due to the limited table width, and it is easy for it to tilt. This tilt will cause the contact angle between the saw blade and the atrium to be unstable during the cutting process, resulting in an uneven cut surface of the atrium. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an aluminum alloy door and window profile cutting device to solve the technical problem that the narrow cutting table of the cold saw cutting machine results in an uneven cutting surface in the atrium.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy door and window profile cutting device, including a base, a support assembly installed on one side of the base, the support assembly including a first fixing block, a second fixing block and a third fixing block, a first support frame installed on the top of the first fixing block, a connecting column fixed on the top of the second fixing block and the third fixing block, a second support frame provided on the top of the connecting column, a first cavity opened inside the first fixing block, a second cavity opened inside the second fixing block, a protrusion provided at one end of both the second fixing block and the third fixing block, and one end of the third fixing block welded to one side of the base.

[0007] By adopting the above technical solution, the problem of uneven cutting surface of the atrium caused by the narrow width of the cutting table of the cold saw cutting machine is solved. Before cutting the atrium, the first fixed block and the second fixed block are pushed to one side, so that the first support frame of the first fixed block and the second support frame of the top of the second fixed block and the top of the third fixed block provide horizontal support for one end of the atrium, thereby making the atrium horizontally placed on the base.

[0008] The present invention is further configured such that the size of the protrusion at the end of the second fixing block is equal to the inner wall size of the first cavity, and the size of the protrusion at the end of the third fixing block is equal to the inner wall size of the second cavity.

[0009] Preferably, the second fixing block is sleeved on the third fixing block, and the first fixing block is sleeved on the second fixing block. The second fixing block and the third fixing block control the movement distance of the first fixing block and the second fixing block respectively through the protrusions at their ends.

[0010] The present invention is further configured such that a second groove is provided on the top of both the first fixing block and the second fixing block, and the width of the second groove is equal to the width of the connecting column.

[0011] Preferably, when the first fixing block, the second fixing block, and the third fixing block are stored together, the connecting post at the top of the second fixing block and the third fixing block is stored in the second groove.

[0012] The present invention is further configured such that four sets of first pulleys are installed at the bottom of the first fixing block, and the first pulleys are located at the bottom corners of the first fixing block.

[0013] Preferably, when the first fixed block moves to one side, the first fixed block slides to one side via the first pulley at the bottom, thereby reducing the friction of the first fixed block moving on the ground.

[0014] The present invention is further configured such that a through groove is provided on one side of the first cavity.

[0015] Preferably, since the top of the first cavity and the second cavity are provided with grooves, dust will enter the interior of the first cavity and the second cavity. When the first fixing block, the second fixing block and the third fixing block are stored together, the third fixing block will push the dust in the second cavity into the first cavity, and the dust in the first cavity will be pushed out of the first cavity by the second fixing block through the groove.

[0016] The present invention is further configured such that the top walls of the first support frame and the second support frame are on the same horizontal plane as the top wall of the base.

[0017] Preferably, the first support frame and the second support frame provide horizontal support for the atrium placed on top of the base.

[0018] The present invention is further configured such that a fixing column is fixed to the top of the base, a cutter is movably installed on one side of the fixing column, a cutting blade is provided inside the cutter, a motor is installed on one side of the cutter, and a control lever is fixed to one end of the cutter.

[0019] Preferably, the operator can use a lever to push the cutter inside the cutter downwards to make the cut.

[0020] The present invention is further configured such that a cutting groove is provided on the top of the base, and fixing plates are fixed on both sides of the cutting groove. A pressing plate is provided on one side of a set of fixing plates, and a lead screw is connected to one side of the pressing plate. A fixing frame is sleeved on the outer wall of the lead screw, and a handle is installed at the end of the lead screw.

[0021] Preferably, the extrusion plate clamps and fixes the atrium with the fixing plate to prevent the atrium from shaking during the cutting process.

[0022] The present invention is further configured such that a limiting block is provided at the bottom of the extrusion plate, and a limiting groove is provided at the top of the base.

[0023] Preferably, when the screw drives the extrusion plate to move towards the fixed plate, the limiting groove limits the movement direction of the limiting block, thereby enabling the extrusion plate to move horizontally along the limiting groove.

[0024] In summary, the present invention has the following main advantages: This utility model solves the problem of uneven cutting surfaces in the atrium caused by the narrow cutting table of a cold saw cutting machine by setting up a base, a first fixing block, a second fixing block, a third fixing block, a first support frame, and a second support frame. Before cutting the atrium, the first fixing block and the second fixing block are pushed to one side, so that the first support frame of the first fixing block, the top of the second fixing block, and the second support frame of the top of the third fixing block provide horizontal support for one end of the atrium, thereby allowing the atrium to be placed horizontally on the base.

[0025] This invention solves the problem of the atrium shaking during the cutting process by setting up a fixed plate, a pressing plate, a lead screw, a fixing block, and a handle. Rotating the handle causes the lead screw to rotate. Since the lead screw and the fixing block are connected by threads, the lead screw can push the pressing plate towards the atrium. The pressing plate presses and fixes the outer wall of the atrium, so that the pressing plate and the fixing plate clamp and fix the two sides of the atrium. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] First embodiment:

[0031] Please see Figure 1 — Figure 4The system includes a base 1, with a support assembly mounted on one side of the base 1. The support assembly includes a first fixing block 4, a second fixing block 5, and a third fixing block 6. A first support frame 402 is mounted on the top of the first fixing block 4. A connecting column 503 is fixed on the top of the second fixing block 5 and the third fixing block 6. A second support frame 504 is provided on the top of the connecting column 503. A first cavity 404 is provided inside the first fixing block 4, and a second cavity 501 is provided inside the second fixing block 5. A protrusion 502 is provided at one end of both the second fixing block 5 and the third fixing block 6. One end of the third fixing block 6 is welded to one side of the base 1. This solves the problem that the narrow cutting table of the cold saw cutting machine results in an uneven cutting surface in the atrium. Before cutting the atrium, the first fixing block 4 and the second fixing block 5 are pushed to one side, so that the first support frame 402 of the first fixing block 4 and the second support frame 504 on the top of the second fixing block 5 and the top of the third fixing block 6 provide horizontal support for one end of the atrium, thereby allowing the atrium to be placed horizontally above the base 1.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The size of the end protrusion 502 of the second fixing block 5 is equal to the inner wall size of the first cavity 404, and the size of the end protrusion 502 of the third fixing block 6 is equal to the inner wall size of the second cavity 501. The second fixing block 5 is sleeved on the third fixing block 6, and the first fixing block 4 is sleeved on the second fixing block 5. The second fixing block 5 and the third fixing block 6 control the movement distance of the first fixing block 4 and the second fixing block 5 respectively through the end protrusions 502.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The top of the first fixing block 4 and the second fixing block 5 are both provided with a second groove 505, and the width of the second groove 505 is equal to the width of the connecting post 503. When the first fixing block 4, the second fixing block 5 and the third fixing block 6 are stored together, the connecting post at the top of the second fixing block 5 and the third fixing block 6 is stored in the second groove 505.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The bottom of the first fixed block 4 is equipped with four sets of first pulleys 401, and the first pulleys 401 are located at the bottom corners of the first fixed block 4. When the first fixed block 4 moves to one side, the first fixed block 4 slides to one side through the first pulleys 401 at the bottom, thereby reducing the friction of the first fixed block 4 moving on the ground.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 4A through groove 405 is provided on one side of the first cavity 404. Since the top of the first cavity 404 and the second cavity 501 are provided with grooves 505, dust will enter the interior of the first cavity 404 and the second cavity 501. When the first fixing block 4, the second fixing block 5 and the third fixing block 6 are stored together, the third fixing block 6 will push the dust in the second cavity 501 into the first cavity 404. The dust in the first cavity 404 will be pushed out of the first cavity 404 by the second fixing block 5 through the through groove 405.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The top walls of the first support frame 402 and the second support frame 504 are on the same horizontal plane as the top wall of the base 1, and the first support frame 402 and the second support frame 504 provide horizontal support for the atrium placed on top of the base 1.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 A fixed column 101 is fixed to the top of the base 1. A cutter 2 is movably installed on one side of the fixed column 101. A cutter 201 is installed inside the cutter 2. A motor 202 is installed on one side of the cutter 2. A control lever 203 is fixed to one end of the cutter 2. Personnel can use the control lever 203 to push the cutter 201 inside the cutter 2 downward to cut.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 The base 1 has a cutting groove 102 on its top. Fixing plates 103 are fixed on both sides of the cutting groove 102. A pressing plate 3 is provided on one side of a set of fixing plates 103. A lead screw 302 is connected to one side of the pressing plate 3. A fixing frame 303 is fitted on the outer wall of the lead screw 302. A handle 304 is installed at the end of the lead screw 302. The pressing plate 103 clamps and fixes the atrium with the fixing plate 103 to prevent the atrium from shaking during the cutting process.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The bottom of the extrusion plate 3 is provided with a limiting block 301, and the top of the base 1 is provided with a limiting groove 305. When the screw 302 drives the extrusion plate 3 to move towards the side of the fixed plate 103, the limiting groove 305 limits the movement direction of the limiting block 301, thereby enabling the extrusion plate 3 to move horizontally along the limiting groove 305.

[0040] Second embodiment:

[0041] Please see Figure 5Two sets of second pulleys 506 are installed at one bottom end of the second support block 5. When the first support block 4 and the second support block 5 are fully opened, the four sets of first pulleys 401 at the bottom of the first support block 4 and the two sets of second pulleys 506 at the bottom of the second support block 5 together support the first support block 4 and the second support block 5, so that the first support block 4, the second support block 5 and the third support block 6 are horizontally supported at one end of the atrium placed on the top of the base 1 by the first support frame 402 and the second support frame 504. A first groove 406 is provided at one bottom end of the first support block 4. When the second support block 5 is retracted into the first support block 4, the first groove 406 provides storage space for the second pulleys 506.

[0042] In practical operation, before cutting the atrium, the atrium is placed on top of the base 1, and one end of the atrium is placed on the first support frame 402 on top of the first support block 4. Then, the atrium is pushed to one side of the first support block 4 so that the cutting line of the atrium and the slice 201 are on the same vertical plane. During the movement of the atrium and the first support block 4, the first support block 4 slides to one side through the four sets of first pulleys 401 installed at the bottom, and the first support block 4 is connected to the protrusion 502 at the end of the second support block 5 through the inner wall of its internal first cavity 404. When the second support block 5 contacts the first support block 4, it causes the second support block 5 to slide to one side along with the first support block 4. When the second support block 5 slides to the point where the inner wall of the end of the second cavity 501 inside it contacts the protrusion 502 at the end of the third support block 6, the second support block 5 stops sliding. When the inner wall of the end of the first cavity 404 inside the first support block 4 contacts the protrusion 502 at the end of the second support block 5, the first support block 5 stops sliding. The first support frame 402 at the top of the first support block 4, together with the second support block 5 and the second support frame 504 at the top of the third support block, supports the atrium, so that the atrium is placed horizontally. Then, rotate the handle 304, which drives the lead screw 302 to rotate. Since the lead screw 302 is connected to the fixing block 303 by a thread, the lead screw 302 can push the extrusion plate 3 towards the atrium. The extrusion plate 3 presses and fixes the outer wall of the atrium. After the atrium is supported and fixed, the motor 202 drives the slice 201 to rotate at high speed. The operator pushes the slice 201 downward through the control lever 203, so that the high-speed rotating slice 201 cuts the atrium.
