Description

Technical Field

[0001] The present invention relates to the technical field of cutting sawing machines, especially the cutting sawing machine for broken bridge aluminum profiles. Background Art

[0002] In the prior art, the broken bridge aluminum alloy profile is a building material with heat insulation performance. Between two aluminum alloy profiles that remain integral, a heat insulation material (such as PA66 nylon) is used for isolation, so as to avoid the problem of rapid heat transfer caused by the fast heat conduction characteristic of aluminum alloy itself in one-piece molding. This type of aluminum alloy profile is widely used and is often used as a frame material in building applications such as doors, windows, curtain walls, and sun rooms. Due to its good heat insulation effect, it can effectively reduce the energy waste and environmental protection problems caused by the indoor-outdoor temperature difference.

[0003] When the broken bridge aluminum alloy profile in the prior art is in use, since it is often needed for the splicing of doors and windows, it is usually necessary to cut a 45-degree angle to splice into a 90-degree corner. The commonly used means is to select and work through a saw blade with adjustable angle or multiple saw blades with preset angles. For example, the patent document with the publication number CN 114260747 A discloses an aluminum profile cutting tooling for processing broken bridge aluminum alloy windows, including a cutting table, a dust suction unit, a transmission unit, and a clamping unit. The clamping unit is used to fix the broken bridge aluminum alloy profile during cutting and achieve intermittent feeding.

[0004] However, the above invention has the following deficiencies: In actual use, since the broken bridge aluminum alloy profile often has front and back sides, when a 45-degree cut is required, the cutting direction needs to be repeatedly adjusted. The prior art usually cuts through a double-headed cutting method to achieve cutting in two directions at a time, and there is no need to frequently adjust the saw blade angle to meet the production requirements. However, for doors and windows in the shape of "day", that is, the middle horizontal bar needs to be cut at 45 degrees from both sides in two directions, forming a sharp right-angle corner at the middle position of the end to cooperate with the connection of two adjacent profiles. But in the prior art during positioning, the cylinder is still simply used for pressing. Therefore, when it is necessary to continue cutting in a different direction, repeated positioning is relatively difficult, seriously affecting the cutting efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a cutting sawing machine for broken bridge aluminum profiles, so as to solve the problem proposed in the above background art that for doors and windows in the shape of "day", that is, the middle horizontal bar needs to be cut at 45 degrees from both sides in two directions, forming a sharp right-angle corner at the middle position of the end to cooperate with the connection of two adjacent profiles.

[0033] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] The present invention provides a thermal break aluminum profile cutting sawing machine through improvement. The technical solution of the present invention is:

[0035] like Figures 1 to 7 As shown, an embodiment of the present invention provides a thermal break aluminum profile cutting sawing machine, comprising a first cutting device 2, wherein:

[0036] The first cutting device 2 includes a box body 21, a connecting plate 22, a mounting box, a mounting plate 24 and a clamping device 26. The connecting plate 22 is fixedly connected to one side of the box body 21. The mounting plate 24 is provided on the side of the box body 21 away from the connecting plate 22. The clamping device 26 is provided on the mounting plate 24. The mounting box is rotatably provided on the connecting plate 22. The mounting box is used to drive the saw blade 232 to rotate and the saw blade 232 to move linearly.

[0037] The clamping device 26 includes a first cylinder 261, a connecting rod 262, a driving plate 263, a rope 264, a second cylinder 265, a positioning plate 266, a connecting ear 267 and a clamping head 27, wherein the first cylinder 261 is fixedly connected to the mounting plate 24, the output end of the first cylinder 261 is drivingly connected to the connecting rod 262, the driving plate 263 is slidably connected to the connecting rod 262, and the positioning plate 266 is fixedly connected to the end of the connecting rod 262 away from the first cylinder 261. , both sides of the positioning plate 266 are fixedly connected with connecting ears 267, the clamping head 27 is rotatably connected to the connecting ears 267, one end of the second cylinder 265 is fixedly connected to the positioning plate 266, and the output end of the second cylinder 265 is fixedly connected to the driving plate 263, and the upper end of the driving plate 263 is fixedly connected to one end of the rope 264, and the other end of the rope 264 passes through the positioning plate 266 and is fixedly connected to the upper side of the clamping head 27, and the clamping head 27 is used to clamp the broken bridge aluminum profile.

[0038] Working principle: When in use, the clamping head 27 is used to clamp and fix the thermally broken aluminum profile. When the second cylinder 265 is extended, the rope 264 is tightened, driving the clamping head 27 to rotate upward. The clamping head 27 cooperates with the positioning plate 266 to achieve vertical upward clamping. The first cylinder 261 is extended, driving the connecting rod 262, the positioning plate 266 and the clamping head 27 to move to the cutting position of the saw blade 232, starting the saw blade 232 and causing the saw blade 232 to move to achieve cutting;

[0039] When bidirectional 45-degree cutting is required, it is only necessary to adjust the angle of the mounting box before cutting so that the saw blade 232 is in the 45-degree cutting direction. After one cutting, the first cylinder 261 and the second cylinder 265 are both retracted, the rope 264 is stretched and relaxed, and the clamping head 27 rotates downward under the action of gravity and cooperates with the positioning plate 266. After the first cylinder 261 extends again, it cooperates with the connecting plate 22 to press the clamping head 27 from both sides to prevent it from rotating. Then, the saw blade 232 is started again to achieve bidirectional cutting of the broken bridge aluminum profile to form a 90-degree sharp angle in the middle.

[0040] Moreover, when the present application is used, since the clamping device 26 changes direction quickly, even if the first cutting device 2 is used alone, it can achieve rapid reversal without the need to turn the entire saw blade 232 and its driving device as a whole, thereby improving cutting efficiency.

[0041] Furthermore, the clamping head 27 includes a connecting column 271, a first sliding plate 272, a sliding rod 274, a fixing plate 275, a third cylinder 276, and a second sliding plate 277, wherein:

[0042] The connecting column 271 is rotatably connected to the connecting ear 267, the rope 264 is fixedly connected to the upper side of the connecting column 271, and a first sliding plate 272 is provided on the connecting column 271. A plurality of parallel sliding rods 274 are fixedly connected to the first sliding plate 272, and one end of the sliding rod 274 away from the first sliding plate 272 is fixedly connected to the same fixed plate 275. The sliding rod 274 is slidably connected to the second sliding plate 277, one end of the third cylinder 276 is fixedly connected to the fixed plate 275, and the output section of the third cylinder 276 is fixedly connected to the second sliding plate 277.

[0043] Preferably, the end of the connecting column 271 away from the connecting ear 267 is fixedly connected to the sliding block 278, the first sliding plate 272 is provided with a sliding groove, the sliding block 278 is slidably connected to the sliding groove, and both ends of the sliding groove are slidably connected to the clamping block 279, and the clamping block 279 is fixed with a limiting telescopic rod 280 on one side corresponding to the sliding block 278, and the end of the limiting telescopic rod 280 away from the clamping block 279 is fixedly connected to the sliding block 278.

[0044] Preferably, both sides of the first sliding plate 272 and the fixed plate 275 are fixedly connected with positioning flanges 273, and the position of the connecting plate 22 corresponding to the positioning flange 273 is fixedly connected with a positioning block 221, and the clamping head 27 includes at least a first working state and a second working state;

[0045] When the clamping head 27 is in the first working state, the third cylinder 276 extends, the first sliding plate 272 is located above the connecting ear 267, the connecting column 271 is in a vertical state, and the connecting column 271 rests on the positioning plate 266 under the tension of the rope 264;

[0046] When the clamping head 27 is in the second working state, the third cylinder 276 retracts, the first sliding plate 272 is located below the connecting ear 267, and the connecting column 271 is in a vertical state. The connecting column 271 naturally rests on the positioning plate 266 under the action of gravity;

[0047] The connecting post 271 in the first working state and the connecting post 271 in the second working state form an angle of 180 degrees with each other.

[0048] Working principle: When in use, the clamping head 27 is used to clamp and fix the broken bridge aluminum profile. When the first cylinder 261 is retracted, the broken bridge aluminum profile is placed between the first sliding plate 272 and the second sliding plate 277, and placed between the two clamping blocks 279. After the positioning is completed, the third cylinder 276 is started to press the broken bridge aluminum profile between the first sliding plate 272 and the second sliding plate 277. Assuming that the clamping head 27 is in the first working state at this time, the first cylinder 261 extends, driving the connecting rod 26 2 moves together with the positioning plate 266 and the clamping head 27 to the cutting position of the saw blade 232 until the positioning flange 273 contacts the positioning block 221. At this time, the sliding block 278 can continue to slide. After the limiting telescopic rod 280 is extended to the limit, it drives the clamping block 279 to approach and press the thermally broken aluminum profile, realizing three-way pressing and improving cutting stability. The positioning flange 273 and the positioning block 221 improve the positioning accuracy, and the saw blade 232 is started and moved to achieve cutting;

[0049] When bidirectional 45-degree cutting is required, it is only necessary to adjust the angle of the mounting box before cutting so that the saw blade 232 is in a 45-degree cutting direction. After one cutting, the first cylinder 261 and the second cylinder 265 are both retracted, the third cylinder 276 remains extended and clamped, the rope 264 is stretched and relaxed, and the connecting column 271 rotates downward under the action of gravity and cooperates with the positioning plate 266. After the first cylinder 261 is extended again, until the positioning flange 273 contacts the positioning block 221, the sliding block 278 can still continue to slide. After the limiting telescopic rod 280 is extended to the limit, it drives the other clamping block 279 to approach and press the broken bridge aluminum profile, realizing three-way compression and improving cutting stability. Then the saw blade 232 is started again to achieve bilateral cutting of the broken bridge aluminum profile to form a 90-degree sharp angle in the middle.

[0050] After the cutting is completed, only the first cylinder 261 and the third cylinder 276 need to retract to cut the material. Since the thermally-broken aluminum profile has a small flipping displacement, occupies a small space, and is easy to turn, even if the first cutting device 2 is used alone, it can achieve rapid reversal without the need to turn the entire saw blade 232 and its drive device as a whole, thereby improving cutting efficiency.

[0051] Furthermore, the installation box includes a shell 231, a saw blade 232 and a first servo motor 233. The shell 231 is rotatably connected to the connecting plate 22. The first servo motor 233 is fixedly connected to the connecting plate 22. The first servo motor 233 is used to control the rotation angle of the shell 231. A saw blade 232 is provided in the shell 231. A driving device for driving the saw blade 232 to rotate and the saw blade 232 to move in a straight line is provided in the shell 231, and both are provided in the shell 231 and can rotate synchronously with the rotation of the shell 231. How to drive the saw blade 232 to rotate and move in a straight line is the existing technology in this field and will not be repeated here.

[0052] A second slide groove 213 is provided at the upper end of the box body 21, and a second screw rod 214 is rotatably connected in the second slide groove 213. A second servo motor 215 is fixedly connected to the box body 21, and the output end of the second servo motor 215 is driven and connected to the second screw rod 214. The second screw rod 214 is a bidirectional screw rod, and the threads of different rotation directions of the second screw rod 214 are respectively connected to the mounting plates 24. The two mounting plates 24 are symmetrically arranged, so that the saw blade 232 of the first cutting device 2 is clamped on both sides of the cutting position, and can be flipped immediately after clamping without the need for repeated positioning.

[0053] A second slot 212 is formed on the box body 21 , a first slot 211 is formed on one side of the box body 21 , the second slot 212 is connected to the first slot 211 , and a collection box 25 is slidably connected to the first slot 211 to facilitate the collection of cuttings.

[0054] It also includes a second cutting device 3 and a machine base 1. The second cutting device 3 has the same structure as the first cutting device 2. The machine base 1 includes a carrier 11, a first screw rod 12 and a third servo motor 13. The box 21 of the first cutting device 2 is fixedly connected to one end of the carrier 11. The carrier 11 is provided with a first slide groove 111. The first slide groove 111 is rotatably connected to the first screw rod 12. The third servo motor 13 is fixedly connected to the machine base 1. The output end of the third servo motor 13 is transmission-connected to the first screw rod 12. The first screw rod 12 is transmission-connected to the box 21 of the second cutting device 3. The principle of double-head cutting is adopted to improve the cutting efficiency, that is, the angle of the shell 231 of the first cutting device 2 can be different from the angle of the shell 231 of the second cutting device 3. A long broken bridge aluminum profile is passed through the clamping device 26 of the first cutting device 2 and the second cutting device 3, and can be cut in different directions at the same time to reduce the frequency of flipping.
