Description

Technical Field

[0001] The invention relates to the field of aluminum material cutting, and in particular to an aluminum material sawing device capable of preventing aluminum fragments from splashing. Background Art

[0002] Aluminum sawing devices are specialized equipment designed for efficient and precise cutting of aluminum profiles, aluminum plates and other aluminum alloy materials. They are usually composed of a sturdy frame, a high-speed motor-driven high-quality carbide circular saw blade, and a precise feed system. They can achieve fast, straight, burr-free, and high-quality cuts.

[0003] The Chinese patent publication number "CN115519180A" discloses "a machine frame having a processing plane provided on the frame; a sawing device including a transverse track provided on the frame, a saw frame moving along the transverse track, a saw frame reciprocating mechanism for driving the saw frame to move, a saw disc rotatably provided on the saw frame, and a saw disc rotation driving mechanism provided on the saw frame for driving the saw disc to rotate; a steel plate feeding device for feeding the steel plate to be cut onto the processing plane; and a steel plate pressing device including a pressing block located above the processing plane and a pressing block lifting mechanism for driving the pressing block to rise and fall."

[0012] As a further solution of the present invention, a stopper is fixedly connected to the interior of each pair of connecting blocks, and the front portion of the stopper is in contact with the rear portion of the docking block.

[0013] As a further solution of the present invention, the front and rear parts and both sides of the shield are provided with self-locking structures, the self-locking structure includes a sliding block, a sliding groove is opened on one side of the interior of the shield, the sliding block is slidably connected to the inside of the sliding groove, and the sliding groove and the lifting groove are connected to each other, two springs are fixedly connected between the front part of the sliding block and the sliding groove, one side of the sliding block passes through one side of the shield and is fixedly connected to an extrusion block, a slot is opened inside the round block and passes through the outer surface, and the outer surface of the lifting block is fixedly connected to a connecting rod.

[0014] As a further solution of the present invention, a receiving groove is provided inside the protective cover, and a blocking piece is fixedly connected to the front portion of the sliding block and located inside the receiving groove.

[0015] As a further solution of the present invention, the sliding block is adaptively matched with the slot, the top of the extrusion block is arranged in an inclined surface, and the bottom of the connecting rod is located directly above the extrusion block.

[0017] As a further solution of the present invention, the trapezoidal block is adaptively matched with the tension block, and the tension block is located at the top of the lifting trough.

[0018] The beneficial effects of the present invention are as follows:

[0019] By setting up a downward shielding structure that can be automatically triggered by the cutting action, elastic elements are used to drive multiple independently movable shielding rods to press down during the cutting process and adaptively fit with the moving aluminum plate, effectively filling the gap between the plate and the shield trough, significantly improving the airtightness of the cutting area, greatly reducing the splash range of cutting waste, and improving the safety of the working environment.

[0020] Through the interaction between the shielding rod and the aluminum plate during movement and the reset force provided by the coil spring, the shielding rod continuously applies downward pressure as the plate moves. This mechanism can automatically form an effective clamp on the front and rear ends of the aluminum plate during cutting without the need for additional clamps, preventing the plate from displacement or vibration during the cutting process, ensuring cutting accuracy and stability, and simplifying the operation steps.

[0021] By setting up a self-locking structure, the lifting and lowering drive self-locking structure of the cutting saw can be operated, so that the lowering action of the cutting saw synchronously triggers the unlocking of the shielding rod. When the lifting block moves downward, its connecting rod will press the extrusion block with an inclined design, release the lock on the shielding rod fixing part, and allow the downward-pressing shielding structure to automatically enter the working state, realizing the automated coordination of the cutting process and the protection / clamping process.

[0022] The self-locking structure and its shielding rod plate design can reliably fix the shielding rod plate when the shielding rod plate is in a high position in the non-cutting state, keeping the material trough fully open. This ensures that aluminum plates of different thicknesses can enter and exit the shield smoothly and unobstructed, improving the versatility of the equipment and feeding convenience.

[0023] Through the cooperation of the fixed box, trapezoidal block and tension block and docking groove on the shielding rod plate set on the lifting mechanism, when the cutting is completed and the cutting saw is lifted, the shielding rod is automatically pulled and the downward-pressed shielding structure is reset to the initial locking position. This design realizes the automatic recovery and re-locking of the protection / clamping device without manual intervention, improves the automation level and operating efficiency of the equipment, and prepares for the next cutting cycle.

[0024] The connecting flange design on the side of the shield facilitates the connection of an external dust collection device. Combined with the relatively closed space created by the dynamic sealing structure, the negative pressure effect inside the shield is effectively enhanced, which significantly improves the efficiency of the dust collection device in collecting aluminum waste generated by cutting, further optimizing the working environment.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0039] like Figure 1 - Figure 12 As shown, an aluminum material sawing device for preventing aluminum fragments from splashing comprises two brackets 1, a guard 2 is fixedly installed on the top of the two brackets 1, and is characterized in that: a conveyor belt 1 3 is connected to the front between the two brackets 1, a conveyor belt 2 10 is connected to the rear between the two brackets 1, the tops of the two brackets 1 are fixedly connected to columns 4, one side of the two columns 4 is provided with a through slot 5 running through the other side, the outer surface of the column 4 is slidably connected to a lifting block 6 through the through slot 5, the rear parts of the two lifting blocks 6 are fixedly connected to a connecting frame 8, a cutting saw 9 is fixedly connected between the two connecting frames 8, the bottoms of the two columns 4 are fixedly connected to a cylinder 1 7, the output shaft of the cylinder 1 7 passes through the interior of the through slot 5 and is fixedly connected to the lifting block 6, and a downward pressure shielding structure 14 is provided on the front and rear parts of the interior of the bracket 1;

[0040] The downward-pressing shielding structure 14 includes a plurality of shielding rods 20. A material trough 38 is provided in the rear portion of the interior of the shield 2. A baffle 15 is slidably connected to the top of the material trough 38 in the interior of the shield 2. A plurality of springs 16 are fixedly connected between the top of the baffle 15 and the interior of the shield 2. The bottom of the baffle 15 is fixedly connected to a plurality of pairs of mutually fitting connecting blocks 19. Each pair of connecting blocks 19 is rotatably connected to a docking block 21 in the interior. The bottom of the docking block 21 is fixedly connected to the top of the shielding rod 20.

[0041] During the actual operation, the aluminum plate to be cut is placed on the outer surface of the conveyor belt 1 3, and then the conveyor belt 1 3 and the conveyor belt 2 10 are used to convey the aluminum plate along the material trough 38 at the front to the inside of the protective cover 2, and then the two cylinders 1 7 are started to drive the two lifting blocks 6 to slide down along the two through slots 5, thereby driving the two connecting frames 8 and the cutting saw 9 to slide down synchronously until the saw blade of the cutting saw 9 is located between the conveyor belt 1 3 and the conveyor belt 2 10, that is, the aluminum plate is cut. At this time, the fixed cover of the cutting saw 9 is located at the top of the protective cover 2. After the cutting is completed, the aluminum plate is discharged through the material trough 38 at the front, and the cut aluminum plate can be discharged;

[0042] During the cutting process of the aluminum plate, the fixing effect of the baffle 15 is released, and the several springs 16 are no longer restricted, so that they rebound, driving the baffle 15 and the several shielding rods 20 to move downward, so that the several shielding rods 20 squeeze the top of the aluminum plate. At this time, the aluminum plate continues to move toward the rear, which can drive the several shielding rods 20 at the front to rotate backward. Since the movement of each shielding rod 20 is independent, the shielding rod 20 located at the top of the aluminum plate can fill the gap between the aluminum plate and the material trough 38, thereby ensuring that the interior of the shield 2 is in a relatively sealed state, thereby effectively preventing the cutting waste of the aluminum from splashing.

[0043] In this embodiment, lifting slots 17 are provided on both sides of the interior of the shield 2 , and round blocks 18 are fixedly connected to the top of both sides of the baffle 15 , and the round blocks 18 are adaptively matched with the lifting slots 17 .

[0044] In this embodiment, a connecting flange 11 is fixedly connected to one side of the shield 2, and the cutting saw 9 is located directly above between the conveyor belt 1 3 and the conveyor belt 2 10;

[0045] By connecting the flange 11 to an external dust collection device, the aluminum waste generated inside the shield 2 can be collected. At the same time, the downward pressure of the shielding structure 14 can ensure that the interior of the shield 2 is in a relatively sealed state, thereby increasing the negative pressure level inside the shield 2 when the external dust collection device is collecting dust, thereby improving the dust collection effect.

[0046] In this embodiment, a coil spring 22 is fixedly connected to the interior of each connecting block 19 , and the inner end of the coil spring 22 is fixedly connected to the docking block 21 .

[0047] In this embodiment, a stopper 23 is fixedly connected to the interior of each pair of connecting blocks 19, and the front portion of the stopper 23 contacts the rear portion of the docking block 21;

[0048] When the aluminum plate moves backward and is squeezed by the shielding rod 20, the shielding rod 20 and the docking block 21 rotate backward, causing the coil spring 22 to be contracted. The restoring elastic force of the coil spring 22 can effectively squeeze and fix the shielding rod 20 and the aluminum plate. Therefore, the front and rear of the aluminum plate can be automatically clamped and fixed by the two symmetrical downward-pressing shielding structures 14, thereby preventing the aluminum plate from shaking when being cut. At the same time, there is no need to set up additional clamps to clamp and fix the aluminum plate.

[0049] In this embodiment, the front and rear portions and both sides of the shield 2 are provided with a self-locking structure 24, which includes a sliding block 27. A slide groove 26 is provided on one side of the interior of the shield 2. The sliding block 27 is slidably connected to the interior of the slide groove 26, and the slide groove 26 is communicated with the lifting groove 17. Two springs 28 are fixedly connected between the front portion of the sliding block 27 and the slide groove 26. One side of the sliding block 27 passes through one side of the shield 2 and is fixedly connected to an extrusion block 30. A slot 29 is provided on the inner surface of the round block 18 and passes through the outer surface. The outer surface of the lifting block 6 is fixedly connected to the connecting rod 25.

[0050] When the round block 18 is located at the top of the lifting groove 17, the sliding block 27 is inserted into the slot 29, so that the round block 18 is fixed and cannot move downward, so that the baffle 15 and the plurality of shielding rods 20 are fixed inside the shield 2, and the material trough 38 is fully opened, thereby allowing aluminum plates of different thicknesses to enter the interior of the shield 2;

[0051] When the lifting block 6 moves downward and the cutting process begins, the lifting block 6 will drive the connecting rod 25 to move downward synchronously, and the bottom of the connecting rod 25 will be squeezed against the top of the extrusion block 30. Since the top of the extrusion block 30 is arranged in an inclined surface, the extrusion block 30 is compressed and will move rearward along the inclined surface, thereby driving the sliding block 27 to move rearward along the slide groove 26. The spring 2 28 is compressed, so the sliding block 27 is separated from the slot 29, so that the round block 18 is no longer fixed, so the several springs 16 rebound, driving the downward pressure shielding structure 14 to operate.

[0052] In this embodiment, a receiving slot 12 is provided inside the shield 2, and a blocking piece 13 is fixedly connected to the front of the sliding block 27 and located inside the receiving slot 12;

[0053] When the sliding block 27 is plugged into the slot 29 , the baffle 13 will block and seal the side of the slide groove 26 . When the sliding block 27 slides toward the rear along the slide groove 26 , the baffle 13 will completely enter the interior of the storage groove 12 and will not affect the movement of the sliding block 27 .

[0054] In this embodiment, the sliding block 27 is adaptively matched with the slot 29 , the top of the extrusion block 30 is arranged in an inclined surface, and the bottom of the connecting rod 25 is located directly above the extrusion block 30 .

[0055] In this embodiment, the outer surfaces of the two connecting rods 25 on the same side are fixedly connected to a fixing box 33, a placement groove 34 is provided inside the fixing box 33, a trapezoidal block 35 is provided inside the placement groove 34, and the side of the trapezoidal block 35 is fixedly connected to an anti-slip block 36, and a plurality of springs 37 are fixedly connected between the anti-slip block 36 and the placement groove 34. The placement groove 34 runs through the side of the fixing box 33, and the outer surfaces of the two round blocks 18 are fixedly connected to the top with a tension block 31, and the side of the tension block 31 is provided with a docking groove 32;

[0056] The fixing box 33 is located at the top of the extrusion block 30. When the sliding block 27 is separated from the slot 29 and the round block 18 slides down along the lifting slot 17, the front of the extrusion block 30 contacts the rear of the connecting rod 25. The connecting rod 25 continues to move downward until the trapezoidal block 35 is located on the top of the tension block 31 at the bottom. The connecting rod 25 and the trapezoidal block 35 continue to move downward. The bottom of the trapezoidal block 35 is squeezed with the top of the tension block 31, so that the trapezoidal block 35 is completely located inside the placement slot 34. The spring three 37 is compressed until the trapezoidal block 35 moves When it moves to the position of the docking groove 32, the spring 37 rebounds, driving the trapezoidal block 35 to engage with the docking groove 32. Therefore, when the cutting is completed, the connecting rod 25 moves up, and through the engagement of the trapezoidal block 35 and the docking groove 32, the circular block 18 is driven to move up, thereby pressing the shielding structure 14 down to reset. When the tension block 31 moves up to the top of the lifting groove 17 again, the top of the trapezoidal block 35 is squeezed with the top of the docking groove 32, and the trapezoidal block 35 returns to the inside of the placement groove 34, and the trapezoidal block 35 is separated from the docking groove 32.

[0057] In this embodiment, the trapezoidal block 35 is adaptively matched with the tension block 31 , and the tension block 31 is located at the top of the lifting groove 17 .

[0058] It should be noted that the present invention is an aluminum material sawing device that prevents aluminum fragments from splashing. When in use, the aluminum plate to be cut is placed on the outer surface of the conveyor belt 1 3, and then the conveyor belt 1 3 and the conveyor belt 2 10 are used to convey the aluminum plate along the material trough 38 at the front to the inside of the protective cover 2, and then the two cylinders 1 7 are started to drive the two lifting blocks 6 to slide down along the two through grooves 5, thereby driving the two connecting frames 8 and the cutting saw 9 to slide down synchronously until the saw blade of the cutting saw 9 is located between the conveyor belt 1 3 and the conveyor belt 2 10, that is, the aluminum plate is cut. At this time, the fixed cover of the cutting saw 9 is located at the top of the protective cover 2. After cutting is completed, it is discharged through the material trough 38 at the front, and the cut aluminum plate can be discharged;

[0059] During the cutting process of the aluminum plate, the fixing effect of the baffle 15 is released, and the plurality of springs 16 are no longer restricted, so that they rebound, driving the baffle 15 and the plurality of shielding rods 20 to move downward, so that the plurality of shielding rods 20 squeeze the top of the aluminum plate. At this time, the aluminum plate continues to move toward the rear, which can drive the plurality of shielding rods 20 at the front to rotate backward. Since the movement of each shielding rod 20 is independent, the shielding rod 20 located at the top of the aluminum plate can fill the gap between the aluminum plate and the material trough 38, thereby ensuring that the interior of the shield 2 is in a relatively sealed state, thereby effectively preventing the cutting waste of the aluminum material from splashing;

[0060] The flange 11 is connected to an external dust collection device to collect aluminum scraps generated inside the shield 2. At the same time, the downward pressure shielding structure 14 ensures that the interior of the shield 2 is relatively sealed, thereby increasing the negative pressure inside the shield 2 when the external dust collection device is collecting dust, thereby improving the dust collection effect.

[0061] When the aluminum plate moves backward and is squeezed by the shielding rod 20, the shielding rod 20 and the docking block 21 rotate backward, causing the coil spring 22 to be contracted. The restoring elastic force of the coil spring 22 can effectively squeeze and fix the shielding rod 20 and the aluminum plate. Therefore, the front and rear parts of the aluminum plate can be automatically clamped and fixed by the two downward-pressing shielding structures 14 that are symmetrical to each other in the front and back, so that the aluminum plate can be prevented from shaking when being cut. At the same time, there is no need to set up additional clamps to clamp and fix the aluminum plate.

[0062] When the round block 18 is located at the top of the lifting groove 17, the sliding block 27 is inserted into the slot 29, so that the round block 18 is fixed and cannot move downward, so that the baffle 15 and the plurality of shielding rods 20 are fixed inside the shield 2, and the material trough 38 is fully opened, thereby allowing aluminum plates of different thicknesses to enter the interior of the shield 2;

[0063] When the lifting block 6 moves down and the cutting process begins, the lifting block 6 will drive the connecting rod 25 to move down synchronously, and the bottom of the connecting rod 25 will be squeezed by the top of the squeezing block 30. Since the top of the squeezing block 30 is arranged in an inclined surface, the squeezing block 30 is pressed and will move rearward along the inclined surface, thereby driving the sliding block 27 to move rearward along the slide groove 26. The second spring 28 is compressed, so the sliding block 27 is separated from the slot 29, so that the round block 18 is no longer fixed. Therefore, the plurality of springs 16 rebound and drive the downward pressure shielding structure 14 to operate. When the sliding block 27 is plugged into the slot 29, the blocking piece 13 will block and seal the side of the slide groove 26. When the sliding block 27 slides rearward along the slide groove 26, the blocking piece 13 will completely enter the interior of the storage groove 12 and will not affect the movement of the sliding block 27.

[0064] The fixing box 33 is located at the top of the extrusion block 30. When the sliding block 27 is separated from the slot 29 and the round block 18 slides down along the lifting slot 17, the front of the extrusion block 30 contacts the rear of the connecting rod 25. The connecting rod 25 continues to move downward until the trapezoidal block 35 is located on the top of the tension block 31 at the bottom. The connecting rod 25 and the trapezoidal block 35 continue to move downward. The bottom of the trapezoidal block 35 is squeezed with the top of the tension block 31, so that the trapezoidal block 35 is completely located inside the placement slot 34. The spring three 37 is compressed until the trapezoidal block 35 moves When it moves to the position of the docking groove 32, the spring 37 rebounds, driving the trapezoidal block 35 to engage with the docking groove 32. Therefore, when the cutting is completed, the connecting rod 25 moves up, and through the engagement of the trapezoidal block 35 and the docking groove 32, the circular block 18 is driven to move up, thereby pressing the shielding structure 14 down to reset. When the tension block 31 moves up to the top of the lifting groove 17 again, the top of the trapezoidal block 35 is squeezed with the top of the docking groove 32, and the trapezoidal block 35 returns to the inside of the placement groove 34, and the trapezoidal block 35 is separated from the docking groove 32.
