[0028] The aluminum sawing machine includes a base 1, a supporting seat 2, a rotating shaft 3, a sliding rod 4, a fixed frame 5, a motor 6, a handle 7, a saw blade 8, a connecting rod 101 and a protective cover 102; the base 1 is rotatably connected to the supporting seat 2, a baffle 2001 is arranged on the supporting seat 2, and a straight groove 2002 is opened on the supporting seat 2; the supporting seat 2 is rotatably connected to the rotating shaft 3; the sliding rod 4 is slidably connected to the rotating shaft 3, and the sliding rod 4 is fixedly connected to the water tank 12; the sliding rod 4 is rotatably connected to the fixed frame 5 The fixed frame 5 is hinged with the pull rod on the piston rod 10, the water pipe 13 is fixedly connected to the inside of the fixed frame 5, and the branch pipe 1301 is located in the fixed frame 5; the fixed frame 5 is bolted with the motor 6; the fixed frame 5 is fixed with the handle 7; the rotating part of the motor 6 is bolted with the saw blade 8, and the rotating part of the motor 6 is rotatably connected to the fixed frame 5; the sliding rod 4 is rotatably connected with the connecting rod 101; the fixed frame 5 is rotatably connected with the protective cover 102, and the protective cover 102 is connected to the connecting rod 101.

[0029] The handle 7 is covered with an anti-slip cover to increase the friction between the handle 7 and the human hand.

[0030] The outlet ends of the branch pipes 1301 are all arranged toward the saw blade 8, so that the water sprayed from the branch pipes 1301 can directly rinse the surface of the saw blade 8, thereby ensuring the rinsing effect.

[0031] The area of ​​the water pipe 13 located in the fixed frame 5 is C-shaped, which increases the cleaning range.

[0032] When the present invention is in use, the workpiece to be cut is first placed on the supporting seat 2 manually, and the workpiece is made to be close to the baffle 2001 and fixed. Then, the handle 7 is manually grasped and pulled to the right, so that the handle 7 drives the slide bar 4, the fixed frame 5, the motor 6 and the saw blade 8 to move synchronously to the right along the rotating shaft 3, until the slide bar 4 stops when it moves to an appropriate distance (the distance is manually adjusted), and then the slide bar 4 is locked, and then the handle 7 is pressed downward, so that the handle 7 drives the fixed frame 5, the motor 6 and the saw blade 8 to rotate downward around the rotating shaft between the slide bar 4 and the fixed frame 5, so that the saw blade 8 cuts the workpiece. , then manually lift the handle 7 upwards, so that the handle 7 drives the fixed frame 5, the motor 6 and the saw blade 8 to move upward and reset, then manually remove the cut workpiece, and perform the cutting operation on the next workpiece. It should be noted that when the handle 7 is manually grasped and pressed downwards, so that the handle 7 drives the fixed frame 5, the motor 6 and the saw blade 8 to rotate upward or downward around the rotating shaft between the slide rod 4 and the fixed frame 5, the connecting rod 101 and the protective cover 102 cooperate with each other to close or open the protective cover 102. The connecting rod 101 and the protective cover 102 are prior art and will not be elaborated in detail here.

[0033] Taking into account that after the aluminum sawing machine has been used for a long time, a large amount of debris adheres to the inside of the fixed frame 5 and the surface of the saw blade 8, which affects the cutting of subsequent workpieces. Therefore, before cutting the subsequent workpieces, the handle 7 is manually grasped and pressed downward, so that the handle 7 drives the fixed frame 5, the motor 6 and the saw blade 8 to rotate downward around the rotating shaft between the slide rod 4 and the fixed frame 5. At the same time, the fixed frame 5 pulls the piston rod 10 out of the cylinder 9 in the direction away from the water tank 12, and the rotating shaft at the connection between the cylinder 9 and the water tank 12 rotates adaptively. The rotating shaft at the connection between the piston rod 10 and the fixed frame 5 rotates adaptively. When the piston rod 10 is pulled out from the cylinder 9 in the direction away from the water tank 12, the outside air flows into the opening of the fixed frame 5 through the cylinder 9, and then passes through the piston head on the piston rod 10 and enters the cylinder 9. Figure 7 As shown in the first left figure, the handle 7 is then lifted upwards, so that the handle 7 drives the fixed frame 5, the motor 6 and the saw blade 8 to rotate upwards around the rotating shaft between the slide rod 4 and the fixed frame 5. At this time, the fixed frame 5 will push the piston rod 10 to return along the cylinder 9 to the direction close to the water tank 12. Since the space between the inside of the cylinder 9 and the piston head on the piston rod 10 is filled with air, when the piston rod 10 moves into the cylinder 9, the air in the cylinder 9 is gradually compressed to form high-pressure gas, so that the piston head on the piston rod 10 is squeezed and stretched open, as shown in FIG. Figure 7 As shown in the first figure on the right, the piston head is fitted with the inner wall of the cylinder 9 to form a closed space. As the piston rod 10 continues to move into the cylinder 9, the air in the cylinder 9 will flow into the water tank 12 through the air pipe 11 to increase the pressure of the water tank 12. Then, the above operation is repeated to pull the fixed frame 5 up and down to increase the gas pressure in the water tank 12. The water in the water tank 12 is continuously sprayed out from the branch pipe 1301 through the water pipe 13 to the inside of the fixed frame 5 and the saw blade 8. The inside of the fixed frame 5 and the saw blade 8 are cleaned to prevent a large amount of dirt from adhering to the inside of the fixed frame 5 and the surface of the saw blade 8 after the aluminum sawing machine has been used for a long time. debris, affecting the cutting of subsequent workpieces; it should be noted that a one-way valve is provided in the air pipe 11 to prevent the gas pressure in the water tank 12 from leaking; it should be noted that the speed of the lifting handle 7 can be manually controlled to control the flow rate of the water flow sprayed from the branch pipe 1301, and the faster the speed of the lifting handle 7 is, the faster the speed of the piston rod 10 squeezes the air inside the cylinder 9; it should be noted that after each cutting of a workpiece is completed, the fixed frame 5 can be manually pulled up and down to make the water in the water tank 12 clean the inside of the fixed frame 5 and the saw blade 8, and provide lubrication for the saw blade 8.

[0034] It is considered that during the process of the saw blade 8 cutting the workpiece, there is a rebound phenomenon of the saw blade 8. The specific reasons include insufficient rigidity of the saw blade 8, improper selection of the saw blade 8, mismatch between the feed speed and the cutting speed, unstable clamping device, wear or passivation of the saw blade, and insufficient cooling and lubrication. When the saw blade 8 rebounds during the cutting process, it is easy to affect the safety of the workers. Therefore, when the saw blade 8 suddenly rebounds during the process of cutting the workpiece, the elastic force on the saw blade 8 will act on the fixed frame 5, so that the fixed frame 5 pushes the piston rod 10 to move into the cylinder 9. Since the space between the inside of the cylinder 9 and the piston head on the piston rod 10 is filled with air, when the piston rod 10 moves into the cylinder 9, the air in the cylinder 9 is gradually compressed to form high-pressure gas, so that the piston head on the piston rod 10 is squeezed open by the high-pressure gas. Figure 7 As shown in the first right, the piston head on the piston rod 10 fits against the inner wall of the cylinder 9 to form a closed space. At this time, when the piston head on the piston rod 10 squeezes the air into high-pressure gas, the piston rod 10 moves very slowly along the cylinder 9, thereby slowing down the kinetic energy of the saw blade 8 when it rebounds, thereby reducing the risk of manual injury.

[0035] Considering that aluminum sawing machines are often used to cut metal precision parts, when the saw blade 8 rebounds during the process of cutting the metal workpiece, due to the relatively slow speed of cutting the metal workpiece, the long-term friction between the saw blade 8 and the metal workpiece will generate a high temperature, causing the saw blade 8 to rebound. When people need to perform inspection and maintenance work, they also need to wait for the saw blade 8 to cool down, which is not convenient for manual rapid inspection and maintenance of the saw blade 8. Therefore, when the saw blade 8 rebounds during the process of cutting the metal workpiece, the piston rod 10 moves into the cylinder 9, and the pressurized gas When the gas enters the air pipe 11, it will enter the water tank 12 filled with water through the air pipe 11, so that the pressure in the water tank 12 increases. Since the inside of the water tank 12 is already in a high-pressure state after the above-mentioned cleaning operation of the saw slice 8, the water in the water tank 12 will be immediately squeezed out from the water pipe 13, and then sprayed from the branch pipe 1301 onto the saw slice 8, so as to cool the saw slice 8, so as to facilitate manual and rapid inspection and maintenance of the saw slice 8. When the water is sprayed from the branch pipe 1301 onto the saw slice 8, the water will also wash away the debris adhering to the surface of the saw slice 8. , which is convenient for manual observation of the saw blade 8; it should be noted that the handle 7 can be manually pushed so that the handle 7 pushes the fixed frame 5, the motor 6 and the saw blade 8 to rotate upward around the rotating shaft between the slide bar 4 and the fixed frame 5 and lift and reset. In this process, the fixed frame 5 squeezes the piston rod 10 into the cylinder 9, so that the air in the cylinder 9 continuously enters the water tank 12 through the air pipe 11, so that the water in the water tank 12 continuously enters the water pipe 13 and is sprayed from the branch pipe 1301 onto the saw blade 8, continuously cooling the saw blade 8. When the piston rod 10 is completely When the saw blade 8 is fully inserted into the cylinder 9, it stops, takes out the workpiece being cut, replaces it with a new workpiece, and checks the degree of damage of the saw blade 8 to select whether it needs to be replaced. It should be noted that compared to directly adding a water pump to spray water, the water pump needs to be able to sense the rebound degree of the saw blade 8 in real time, which requires a more precise sensor, is costly and requires the addition of more electronic components, while the present invention only needs to perform the necessary lifting action to achieve buffering when the saw blade 8 rebounds, and can also timely cool and clean the saw blade 8, thereby improving the maintenance efficiency of workers.

[0036] Example 2

[0037] On the basis of Example 1, Figure 5 and Figure 6 As shown, a blocking piece 103 is also included; two blocking pieces 103 are fixedly connected to the protective cover 102, and the blocking pieces 103 are made of rubber.

[0038] The edge of each baffle 103 is tilted away from the center of the protective cover 102 . When the baffle 103 is pressed against the workpiece, the baffle 103 is tilted and bent away from the saw blade 8 to prevent the baffle 103 from contacting the saw blade 8 .

[0039] It also includes a shift plate 105; a circular groove 2003 is provided on the supporting seat 2; an arc surface 2004 is provided on the supporting seat 2; the shift plate 105 is connected to the supporting seat 2, the lower surface of the shift plate 105 is in contact with the bottom surface of the circular groove 2003, and the upper surface of the shift plate 105 is flush with the upper surface of the supporting seat 2; an avoidance groove 1051 is provided in the middle of the shift plate 105, and the size of the avoidance groove 1051 is the same as that of the straight groove 2002.

[0040] It also includes a toggle bar 104, a gear 106, a rack 107 and a scraper 108; the toggle plate 105 is rotatably connected to the support seat 2; the gear 106 is fixed to the bottom of the toggle plate 105; the support seat 2 is provided with a moving groove 2005, the interior of the moving groove 2005 is slidably connected with the rack 107, and the rack 107 is meshed with the gear 106; the scraper 108 is slidably connected in the straight groove 2002, and the upper part of the scraper 108 is in contact with the arc surface 2004; the support seat 2 is provided with a circular Cavity 2006, the circular cavity 2006 is connected with the straight groove 2002; a toggle bar 104 is fixedly connected to the bottom of the toggle plate 105, the toggle bar 104 is located in the circular cavity 2006, and the height of the toggle bar 104 is the same as the height of the circular cavity 2006; the supporting seat 2 is provided with a leakage port 2007, and the leakage port 2007 is connected with the circular cavity 2006; the base 1 is detachably connected with the supporting seat 2, the base 1 is hollow, and the leakage port 2007 is connected with the base 1.

[0041] The toggle bar 104 is arranged in an arc shape, so as to facilitate pushing the debris and dust into the material leakage port 2007 .

[0042] Considering that a large amount of debris and dust will be generated during the saw blade 8 cutting the workpiece, the debris and dust will splash around to generate dust, affecting the working environment of the workers. Therefore, by setting baffles 103 on both sides of the fixed frame 5, the gap between the two baffles 103 is smaller than the upper surface of the supporting seat 2. When the worker presses the handle 7 to drive the fixed frame 5, the motor 6 and the saw blade 8 to press down, the two baffles 103 will flip downward with the rotation of the protective cover 102 until the two baffles 103 rotate to the bottom of the fixed frame 5. When the two baffles 103 are in close contact with the workpiece surface, the front and rear sides of the fixed frame 5 are blocked to reduce the dust problem caused by the splashing of debris and dust to the surroundings. As the cutting process proceeds, the baffles 103 will deform adaptively to avoid affecting the saw blade 8 in cutting the workpiece. Since the edge of each baffle 103 is tilted away from the center of the protective cover 102, when the baffle 103 is adaptively deformed, the baffle 103 is tilted and bent away from the saw blade 8 to prevent the baffle 103 from contacting the saw blade 8 and preventing the baffle 103 from being worn out quickly.

[0043] Considering that the debris and dust blocked by the baffle 103 and the debris and dust thrown in the rotation direction when the saw blade 8 is cut all fall onto the upper surface of the support seat 2, causing the subsequent workpiece to be unable to be placed stably, affecting the cutting quality of the subsequent workpiece, therefore, by providing a circular groove 2003 and an arc surface 2004 on the support seat 2, the debris and dust fall into the circular groove 2003 and the arc surface 2004 on the support seat 2, and part of the debris and dust directly fall into the straight groove 2002, thereby preventing the debris and dust from falling onto the upper surface of the support seat 2 and affecting the subsequent workpiece. The workpiece is stably placed, and a pull plate 105 is provided. The workpiece is supported by the pull plate 105 to avoid affecting the support of the workpiece by the support seat 2 due to the circular groove 2003. After a lot of debris and dust are accumulated in the circular groove 2003 and the curved surface 2004, the scraper 108 can be manually pushed to move to the left, so that the scraper 108 pushes the debris and dust on the curved surface 2004 into the circular groove 2003, and then the scraper 108 is pulled to the right to reset, and then the rack 107 is manually pulled along the movable groove 2005. The rack 107 moves to the right, so that the rack 107 drives the paddle 105 and the gear 106 to rotate, and the paddle 105 moves all the debris and dust accumulated in the circular groove 2003 to the straight groove 2002 below the circular groove 2003. At the same time, when the rack 107 is manually pulled, the paddle 105 drives the paddle bar 104 to rotate, so that the paddle bar 104 paddles the debris and dust in the straight groove 2002 below the circular groove 2003 to the circular cavity 2006. When the debris and dust in the circular cavity 2006 pass through the leakage port 2007, The debris and dust will fall into the base 1 and be collected, avoiding the problem of unstable placement of subsequent workpieces caused by the accumulation of a large amount of debris and dust in the circular groove 2003 and the curved surface 2004. The rack 107 is then manually pushed to move left along the movable groove 2005 to reset. While resetting, the paddle 105 again pokes the debris and dust accumulated in the circular groove 2003 to ensure that the debris and dust fall into the straight groove 2002. It should be noted that after the paddle 105 is reset, the avoidance groove 1051 is flush with the straight groove 2002 again.
