[0002] Steel is a common building material. It has the advantages of high strength and high toughness, as well as good corrosion resistance and durability. It is widely used in all walks of life. In the process of steel processing, steel cutting machines are needed.

[0003] When the steel cutting machine is working, it can complete the cutting of steel through the high-speed rotating saw blade, and can process the workpiece into the shape required for actual production. The steel cutting machine has the advantages of high precision and high efficiency;

[0004] When the steel cutting machine processes the workpiece, a large amount of debris and dust will be generated. This dust will not only affect the operation of the staff, but also affect the health of the staff if inhaled, which will cause great trouble to the staff and the actual production.

[0005] In order to overcome the above defects, prior art 1 (application number: CN202011077630.0, Chinese patent with application date of 2020-10-10), a dust-free cutting machine, which is fixed to the upper dust hood by connecting one end of the bridge plate, and the other end of the bridge plate is fixed to the lower dust hood, the connecting bridge plate is located at the outlet of the cutting channel, and the connecting bridge plate is located between the extension surfaces on both sides of the cutting blade.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows: the environmentally friendly steel cutting machine capable of preventing dust and reducing temperature adopts a new structural design, so that the nozzle performs reciprocating circular motion around the limit rod, thereby expanding the working range of the nozzle and optimizing the dust reduction effect. At the same time, the material baffle plate is provided to prevent the debris from being scattered and facilitate collection by the staff. During operation, the material baffle plate is in a vibrating state, so that the debris is not adhered to the material baffle plate, which is convenient for subsequent cleaning by the staff. The specific contents are as follows:

[0031] (1) When the environmentally friendly steel cutting machine capable of preventing dust and reducing temperature is in operation, the workpiece is placed on the working plate, and the motor is started. The motor drives the transmission shaft and the cutting disc to rotate. At the same time, the motor is also started. The motor drives the movable block and the cutting disc to move to the front side of the working plate through the threaded rod to complete the cutting work. At the same time, the nozzle will make a reciprocating circular motion. When the nozzle is working, it plays a role in reducing dust and preventing dust from scattering, thereby optimizing work efficiency and ensuring the health of the staff;

[0032] Furthermore, when the transmission shaft moves, it will drive the sliding block, the connecting rod and the auxiliary block to move synchronously. At this time, the nozzle will rotate around the limit rod under the action of the mutual repulsive magnetic force of the first magnet and the second magnet and its own gravity. In this process, the positioning rod plays a role in limiting the rotation range of the nozzle, ensuring the overall stable operation of the device, and the water tank plays a role in providing water source;

[0033] (2) The dust-proof and temperature-reducing environmentally friendly steel cutting machine has a material baffle plate that limits the scattering of debris during the cutting process, ensuring that the debris falls in a concentrated area, making it easier for workers to collect the debris after cutting, thereby improving work efficiency;

[0034] Furthermore, when the sliding block is driven to move by the transmission shaft, the sliding block will drive the connecting shaft to rotate inside the fixed block through the traction rope. When the connecting shaft rotates, it will drive the cam to rotate synchronously. At this time, the cam will intermittently push the auxiliary rod, and then the baffle plate will make reciprocating linear motion in the horizontal direction under the action of the cam, the inner rod and the connecting spring, and then the baffle plate will be in a vibrating state. At this time, the baffle plate itself can not only limit the landing point of the debris, but also will not leave any debris, which is convenient for the staff to collect.

[0035] (3) In the dustproof and temperature-reducing environmentally friendly steel cutting machine, when the connecting shaft is driven to rotate by the traction rope, the connecting shaft will stretch the torsion spring. When the motor rotates and the cutting blade, the transmission shaft and the sliding block move back, the connecting shaft loses the pulling force of the traction rope. At this time, the connecting shaft rotates under the action of the torsion spring. When the connecting shaft rotates, the traction rope will be reeled in, which is convenient for the next use of the sliding block, the traction rope and the connecting shaft, thereby ensuring the smooth operation of the entire device.

[0050] An environmentally friendly steel cutting machine capable of preventing dust and reducing temperature, further comprising:

[0051] A movable block 6, the outer wall of the movable block 6 is in contact with the inner wall of the left connecting plate 2, and the right side surface of the movable block 6 is fixedly connected with a motor 7, a transmission shaft 8, the transmission shaft 8 is fixedly connected to the output end of the motor 7, and a cutting blade 9 is fixedly connected to the surface of the transmission shaft 8;

[0052] A sliding block 10 is slidably arranged inside the right connecting plate 3, and a cross bar 14 is fixedly connected to the inner wall of the right connecting plate 3, and an auxiliary block 15 is slidably arranged inside the right connecting plate 3, and a water tank 12 is bolted to the right side surface of the right connecting plate 3;

[0053] A nozzle 11 is rotatably arranged on the lower surface of the auxiliary block 15, and the nozzle 11 is connected to the water tank 12 through an external hose. A fixed block 19 is fixedly connected to the surface of the rear side of the working plate 1, and an inner connecting rod 25 is slidably arranged inside the fixed block 19, and a material blocking plate 20 is fixedly connected to the end of the inner connecting rod 25, and a connecting shaft 21 is rotatably arranged inside the fixed block 19, and the material blocking plate 20 is semicircular when viewed from above;

[0054] Auxiliary rod 24, auxiliary rod 24 is fixedly connected to the inner wall of the material baffle plate 20, transition shaft 29, transition shaft 29 is fixedly connected to the outer surface of the right connecting plate 3, the surface of the left connecting plate 2 and the surface of the right connecting plate 3 are both provided with through holes, the movable block 6 is threadedly connected to the threaded rod 5, and the lower end of the cutting blade 9 is located inside the cutting groove 28.

[0055] During operation, the workpiece is placed on the working plate 1, and the motor 7 is started. The motor 7 drives the transmission shaft 8 and the cutting disc 9 to rotate, and the motor 4 is also started. The motor 4 drives the movable block 6, the cutting disc 9, and the transmission shaft 8 to move toward the front side of the working plate 1 through the threaded rod 5. The cutting disc 9 and the cutting groove 28 cooperate to complete the cutting work.

[0056] Embodiment 2: Different from Embodiment 1, by setting the nozzle 11 to perform reciprocating circular motion, dust can be prevented from being raised during the cutting process, thereby optimizing the working environment of the staff. Figure 4-Figure 6 As shown:

[0057] The end of the transmission shaft 8 is rotatably arranged inside the sliding block 10, and the sliding block 10 is penetrated by the cross bar 14, and the lower surface of the sliding block 10 is fixedly connected with a connecting rod 13, the lower surface of the connecting rod 13 is fixedly connected to the upper surface of the auxiliary block 15, and the lower surface of the auxiliary block 15 is fixedly connected with a limiting rod 16, and both sides of the limiting rod 16 are convex.

[0058] The surface of the limit rod 16 is sleeved and connected with the nozzle 11, the lower surface of the auxiliary block 15 is fixedly connected with the positioning rod 17, and the positioning rod 17 is initially in contact with the surface of the nozzle 11, the right side surface of the nozzle 11 is fixedly connected with the first magnet 18, and the left side surface of the right connecting plate 3 is fixedly connected with the second magnet 30, the left magnetic pole of the second magnet 30 is the same as the right magnetic pole of the first magnet 18, and the second magnets 30 are evenly spaced on the surface of the right connecting plate 3.

[0059] When the transmission shaft 8 moves, it will drive the sliding block 10, the connecting rod 13, the auxiliary block 15 and the nozzle 11 to move synchronously. At this time, the first magnet 18 on the right side of the nozzle 11 will intermittently approach the second magnet 30. When the first magnet 18 approaches the second magnet 30, the nozzle 11 rotates under the action of the repulsive magnetic force, and when the first magnet 18 is away from the second magnet 30, the nozzle 11 rotates under the action of its own gravity. Repeating the above process, the nozzle 11 will rotate around the limit rod 16 under the action of the repulsive magnetic force between the first magnet 18 and the second magnet 30 and its own gravity. At this time, the nozzle 11 can better reduce dust and deeply optimize the dust reduction effect. In this process, the positioning rod 17 plays a role in limiting the rotation range of the nozzle 11, thereby ensuring the overall stable operation of the device. At the same time, the water tank 12 plays a role in providing water source.

[0060] Embodiment 3: Different from Embodiment 2, the blocking plate 20 is used to limit the falling point of the debris, and the blocking plate 20 is vibrated at the same time, so that no debris remains on the blocking plate 20 itself. Figure 7-Figure 10 As shown:

[0061] A traction rope 23 is fixedly connected to the surface of the sliding block 10, and the traction rope 23 passes through the transition shaft 29, and the end of the traction rope 23 is wrapped and fixedly connected to the surface of the connecting shaft 21, and a cam 22 is fixedly connected to the surface of the connecting shaft 21, and the cam 22 is symmetrically distributed about the center of the connecting shaft 21, and the cam 22 corresponds to the auxiliary rod 24 one by one, and a connecting spring 26 that plays an elastic reset role is fixedly connected to the surface of the inner connecting rod 25, and the other side of the connecting spring 26 is fixedly connected to the inner wall of the fixed block 19, and a torsion spring 27 that plays an elastic reset role is fixedly connected to the surface of the connecting shaft 21, and the other side of the torsion spring 27 is fixedly connected to the inner wall of the fixed block 19.

[0062] During the cutting process, the baffle plate 20 plays a role in limiting the scattering of debris, ensuring that the debris falls in a concentrated point, which makes it easier for the staff to collect the debris after the cutting is completed, thereby improving work efficiency. When the sliding block 10 is driven to move by the transmission shaft 8, the sliding block 10 will drive the connecting shaft 21 to rotate inside the fixed block 19 through the traction rope 23 (the transition shaft 29 maximizes the pulling force of the traction rope 23). When the connecting shaft 21 rotates, it will drive the cam 22 to rotate synchronously. At this time, the cam 22 will intermittently push the auxiliary rod 24. When the auxiliary rod 24 is pushed by the cam 22, the auxiliary rod 24 drives the baffle plate 20 and the inner rod 25 to move in the direction of stretching the connecting spring 26. When the cam 22 continues to rotate until it does not push the auxiliary rod 24, the auxiliary rod 24, the baffle plate 20 and the inner rod 25 return under the action of the connecting spring 26. Back to the original position, repeat the above process, the baffle plate 20 makes reciprocating linear motion in the horizontal direction under the action of the cam 22, the inner rod 25 and the connecting spring 26, and then the baffle plate 20 is in a vibrating state. At this time, the baffle plate 20 itself can not only limit the landing point of debris, but also does not leave any debris itself, which is convenient for the collection work of the staff. When the connecting shaft 21 is driven to rotate by the traction rope 23, the connecting shaft 21 will stretch the torsion spring 27, and when the motor 4 rotates, the cutting blade 9, the transmission shaft 8 and the sliding block 10 move back, the connecting shaft 21 loses the pulling force of the traction rope 23, and the connecting shaft 21 rotates under the action of the torsion spring 27. When the connecting shaft 21 rotates, the traction rope 23 will be reeled in, which is convenient for the next use of the sliding block 10, the traction rope 23 and the connecting shaft 21, thereby ensuring the smoothness of the overall operation of the device.

[0063] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
