Description

Technical Field

[0001] This invention relates to the field of metal cutting, and more particularly to a metal cutting system and method. Background Technology

[0002] High-speed rotating abrasive wheels are often used for cutting metal pipes. These wheels are made by bonding abrasives together with fibers, resin, or rubber. With skilled manual operation, the abrasive wheel can cut quickly and accurately, producing clean, burr-free cuts. When using this type of cutting machine, the operator needs to manually place the metal pipe near the cutting blade and hold the pipe in place during cutting to prevent it from shifting. However, this method also increases the risk of injury to the operator. Summary of the Invention

[0003] In view of this, the technical problem to be solved by the present invention is to provide a metal cutting system and method, wherein the system has an automatic feeding function.

[0004] A continuous casting system includes a cutting table with a cutting groove, a limiting tube fixedly connected to the upper end of the cutting table, an air inlet in the middle of the limiting tube, a feeding port at one end of the limiting tube, and a suction pipe fixedly connected to the other end of the limiting tube. A cutting blade that can move and rotate is provided in the cutting groove.

[0005] Two feeding plates are rotatably connected to the cutting table, and both feeding plates are located inside the limiting tube.

[0006] A baffle is fixedly connected to the upper end of the limiting tube, and the baffle covers the air inlet.

[0007] The baffle has openings at both the left and right ends, and the baffle is arc-shaped.

[0008] The lower end of the cutting table is slidably connected to a movable frame, and a first motor is fixedly connected to the movable frame. The cutting blade is fixedly connected to the output shaft of the first motor.

[0009] A second motor is fixedly connected to the lower end of the cutting table, and a lead screw is fixedly connected to the output shaft of the second motor. The moving frame is threadedly connected to the lead screw.

[0022] The present invention will be described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0023] Referring to 1-5 and 10, schematic diagrams are shown of embodiments of the invention that enable automated feeding. Further,

[0024] A metal cutting system includes a cutting table 101, a cutting groove 102 on the cutting table 101, a limiting tube 201 welded and fixedly connected to the upper end of the cutting table 101, an air inlet 202 in the middle of the limiting tube 201, a feeding port 204 at one end of the limiting tube 201, and a suction pipe 203 welded and fixedly connected to the other end of the limiting tube 201. A cutting blade 305 that can move and rotate is provided in the cutting groove 102.

[0025] When using this system, the staff connects the suction pipe 203 to the air pump, and then uses the conveyor belt to send the metal pipe to be cut into the limiting pipe 201 through the loading port 204. At this time, the air pump draws out the air in the limiting pipe 201, so that the limiting pipe 201 generates negative pressure, and the metal pipe can automatically enter the limiting pipe 201 under the action of negative pressure.

[0026] When the metal tube enters the limiting tube 201, the cutting blade 305 is controlled to move and rotate in the cutting groove 102. When the cutting blade 305 moves past the air inlet 202, it can cut the metal tube. The limiting tube 201 plays a role in limiting the metal tube and preventing the metal tube from moving when it is being cut.

[0027] While the metal pipe is being cut, the resulting metal shavings can be drawn into the suction pipe 203 through the air inlet 202, thereby achieving the function of collecting metal shavings without the need for subsequent cleaning and reducing labor.

[0028] See Figure 8 and Figure 10 A schematic diagram of an embodiment of the present invention that enables automatic unloading is shown. Further,

[0029] Two feeding plates 103 are rotatably connected to the cutting table 101 via a shaft, and both feeding plates 103 are located inside the limiting tube 201.

[0030] When the metal tube is sucked into the limiting tube 201, the metal tube is located above the two feeding plates 103. The two feeding plates 103 support the metal tube. When the metal tube is cut into two sections, the two feeding plates 103 are controlled to rotate downwards, so that the two sections of the metal tube can slide down automatically along the inclined surfaces of the two feeding plates 103, thereby realizing the function of automatic unloading.

[0031] See Figure 1 A schematic diagram of an embodiment of the present invention that allows metal debris to be concentrated inside the baffle 205 is shown. Further,

[0032] The upper end of the limiting tube 201 is fixedly connected to a baffle 205 by bolts, which covers the air inlet 202.

[0033] When the cutting blade 305 cuts the metal tube, the baffle 205 can block the flying sparks and metal debris, thereby avoiding the impact on the surrounding environment and allowing the metal debris to concentrate inside the baffle 205.

[0034] See Figure 1 A schematic diagram illustrating the improved efficiency of collecting metal debris according to the present invention is shown. Further,

[0035] The cover 205 has openings at both ends and is arc-shaped.

[0036] The metal debris produced by cutting the metal tube falls into the baffle 205. When the air pump draws air, the air enters the baffle 205 through the openings at both ends of the baffle 205, and then enters the limiting tube 201 through the air inlet 202. The metal debris will then be driven into the suction tube 203 by the airflow, thus improving the collection of metal debris.

[0037] See Figure 2 and Figure 5-7 The diagram shows an embodiment of the function of moving and cutting a metal tube according to the present invention. Further,

[0038] A movable frame 303 is slidably connected to the lower end of the cutting table 101. A first motor 304 is fixedly connected to the movable frame 303 by bolts. The cutting disc 305 is fixedly connected to the output shaft of the first motor 304.

[0039] The first motor 304 drives the cutting blade 305 to rotate to achieve the function of cutting the metal tube, and the moving frame 303 is controlled to move within the cutting groove 102 to achieve the function of moving and cutting the metal tube.

[0040] See Figure 6-7 A schematic diagram of an embodiment of the present invention that enables the movement of the movable frame 303 is shown. Further,

[0041] The lower end of the cutting table 101 is fixedly connected to the second motor 301 by bolts. The output shaft of the second motor 301 is fixedly connected to the lead screw 302 by a coupling. The moving frame 303 is threadedly connected to the lead screw 302.

[0042] The second motor 301 drives the lead screw 302 to rotate, and the lead screw 302 drives the moving frame 303 to move at the lower end of the cutting table 101, thereby realizing the function of moving the moving frame 303.

[0043] See Figure 9 The diagram shows an embodiment of the present invention in which the feed plate 103 is kept horizontal in its natural state. Further,

[0044] Torsion springs 104 are fixedly connected to the rotating connection points of the two feed plates 103 and the cutting table 101.

[0045] The torsion spring 104 enables the feed plate 103 to rotate downwards while ensuring that the feed plate 103 is in a horizontal state under natural conditions.

[0046] See Figure 7 and Figure 9 A schematic diagram of an embodiment of the present invention that enables automatic unloading is shown. Further,

[0047] Both feed plates 103 are fixedly connected to rotating rods 105 by bolts, and one end of the rotating rod 105 is welded and fixedly connected to a spiral blade 106.

[0048] After the metal tube is cut, the staff controls the spiral blade 106 to drive the rotating rod 105 to rotate, and the rotating rod 105 drives the unloading plate 103 to rotate downward, so as to realize the function of automatic unloading.

[0049] See Figure 6 This illustrates an embodiment of the invention in which the feed plate 103 can be controlled to rotate downwards. Further,

[0050] Two ball joints 306 are welded and fixedly connected to the movable frame 303.

[0051] When cutting metal tubes, the moving frame 303 drives the cutting blade 305 to move to the right, and the moving frame 303 drives the two ball bearings 306 to move to the right. The two ball bearings 306 contact the two spiral blades 106 respectively. Since the two spiral blades 106 are spiral-shaped, when the ball bearings 306 contact the surface of the spiral blades 106, the spiral blades 106 will drive the rotating rod 105 to rotate, thereby driving the unloading plate 103 to rotate downward, realizing the function of automatic unloading, without the need for separate control of the unloading plate 103.

[0053] Step 1: Feed the metal tube to be cut into the limiting tube 201 through the feeding port 204;

[0054] Step 2: Air is drawn out of the limiting tube 201 by an air pump, and the metal tube automatically enters the limiting tube 201 under negative pressure;

[0055] Step 3: Control the cutting blade 305 to move and rotate within the cutting groove 102 to cut the metal tube;

[0056] Step 4: Use an air pump to remove the metal debris generated during the cutting of the metal pipe.

[0057] Step 5: Control the two unloading plates 103 to rotate downwards to unload the two sections of metal pipe.
