DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] Example 1 Reference Figure 1-Figure 4A metal bar cutting device comprises a workbench 1, a cutting mechanism is arranged on the top of the workbench 1, and a tilting platform 6 is fixedly connected to the outer wall of one side of the top of the workbench 1, two arc-shaped bases 4 are arranged on one side of the bottom end of the tilting platform 6, and a moving mechanism is arranged at the bottom of the arc-shaped base 4, a mounting frame 2 5 is arranged above the bottom end of the tilting platform 6, and both ends of the mounting frame 2 5 are welded to the outer wall of the workbench 1, both ends of the top of the mounting frame 2 5 are fixedly connected to an electric push rod 18, and the lower end of the electric push rod 18 is fixedly connected to a vertical plate 17, the bottom end of the vertical plate 17 is hinged with an inclined plate 16, and an elastic mechanism is arranged between the inclined plate 16 and the vertical plate 17, A semi-cylinder 25 is fixedly connected to the outer wall of one side of the vertical plate 17, and an electric push rod 2 19 is set on one side of the electric push rod 18, and the bottom ends of the two electric push rods 2 19 are fixedly connected to the same baffle plate 7, and the bottom ends of the baffle plate 7 and the inclined plate 16 are in contact with the outer wall of the surface of the inclined platform 6. First, the bottom end of the baffle plate 7 is made to contact the surface of the inclined platform 6 through the electric push rod 2 19, and then the vertical plate 17 and the inclined plate 16 are moved upward away from the inclined platform 6 through the electric push rod 18 to ensure that the metal bars can roll down, and then the staff can place multiple metal bars of different diameters on the inclined platform 6 at one time, so that they can be rolled down under their own gravity and inclination. Under the action of the inclined platform 6, it will roll downward until the frontmost metal bar and the baffle plate 7 are at the base, thereby stopping the movement, and then the vertical plate 17 and the inclined plate 16 are moved downward by the electric push rod 18. In this process, the bottom end of the inclined plate 16 will contact the upper surface of the metal bar away from the baffle plate 7. Because the cross-section of the metal bar is circular, as the vertical plate 17 and the inclined plate 16 move downward, the inclined plate 16 is subjected to pressure, thereby stretching the elastic mechanism to deflect, and the outer wall of the inclined plate 16 will always be in contact with the surface of the metal bar. As the inclined plate 16 deflects, the bottom end of the inclined plate 16 will contact another metal bar next to the metal bar. The surface of the metal bar is based until the two metal bars are separated so that the front metal bar is located between the inclined plate 16 and the baffle plate 7, and then the baffle plate 7 is moved upward by the electric push rod 2 19 so that it can roll into the arc base 4, and then it is moved under the cutting mechanism for cutting. In this process, the electric push rod 2 19 makes the baffle plate 7 re-based on the surface of the inclined table 6, and the electric push rod 18 will drive the inclined plate 16 under the vertical plate 17 to separate the metal bars again, avoiding the need to manually place a single metal bar multiple times during cutting, thereby greatly improving work efficiency and reducing labor intensity.

[0020] As a further solution of the present invention, the elastic mechanism includes a sliding cavity 22, the sliding cavity 22 is arranged inside the vertical plate 17, and the sliding cavity 22 is slidably connected to the inner wall above the sliding cavity 22. The inner wall below the sliding cavity 22 is fixedly connected to the fixed plate 20, and a guide column 24 is arranged below the fixed plate 20. A connecting spring 21 is fixedly connected between the sliding cavity 23 and the fixed plate 20, and a traction rope 26 is fixedly connected to the bottom of the sliding cavity 23, and one end of the traction rope 26 passes through the connecting spring 21, the fixed plate 20 and contacts the guide column 24. Thus, it extends through the sliding cavity 22 to the outside of the vertical plate 17, and one end of the traction rope 26 located outside the vertical plate 17 is fixedly connected to the outer wall of one side of the inclined plate 16 under the guidance of the semi-cylinder 25. When the inclined plate 16 deflects to the side away from the semi-cylinder 25, the traction rope 26 can pull the slide plate 23 in the sliding cavity 22 to compress the connecting spring 21 to move downward. When the vertical plate 17 drives the inclined plate 16 to move upward and reset, the inclined plate 16 is reset under the action of the rebound force of the connecting spring 21.

[0021] As a further solution in the present invention, the moving mechanism includes a sliding groove 2, the inner wall of the sliding groove 2 is rotatably connected with a threaded rod 15, and the outer wall of the threaded rod 15 is threadedly slidably connected with a threaded slider 14, a rotating motor 13 is arranged on one side of the threaded rod 15, and the arc base 4 is fixedly connected to the top outer wall of the threaded slider 14. The threaded rod 15 is driven to rotate by the rotating motor 13, so that the threaded slider 14 can slide in the sliding groove 2, thereby enabling the two arc bases 4 to move synchronously.

In this process, the bottom end of the tilting plate 16 will contact with the upper surface of the metal bar away from the baffle plate 7, and because the cross-section of the metal bar is circular, as the vertical plate 17 and the tilting plate 16 move downward, the tilting plate 16 is subjected to pressure, thereby stretching the elastic As the mechanism deflects, the outer wall of the inclined plate 16 will always be in contact with the surface of the metal bar. As the inclined plate 16 deflects, the bottom end of the inclined plate 16 will contact the surface of another metal bar next to the metal bar until the two metal bars are separated, so that the front metal bar is located between the inclined plate 16 and the baffle plate 7. Then, the baffle plate 7 is moved upward by the electric push rod 2 19 so that it can roll into the arc base 4, and then moved under the cutting machine 12 for cutting. In this process, the electric push rod 2 19 makes the baffle plate 7 contact with the surface of the inclined table 6 again, and the electric push rod 18 drives the inclined plate 16 under the vertical plate 17 to separate the metal bars again, avoiding the need to manually place a single metal bar multiple times during cutting, thereby greatly improving work efficiency and reducing labor intensity.

[0025] As a further solution in the present invention, the fixing column 34 is fixedly connected to the inner wall of the arc-shaped base 4, and the outer wall of the fixing column 34 is rotatably connected with the clamping plate 27, and the clamping plate 27 and the inner wall of the arc-shaped base 4 are fixedly connected with the connecting spring 23, and the clamping plate 27 is located in the corresponding arc groove 28, the top of the clamping plate 27 will not protrude in the arc groove 28, and the bottom end of the clamping plate 27 is lower than the top of the push plate 31, so that the outer wall of one side of the two push plates 31 away from each other will contact the bottom end of the clamping plate 27, with the movement of the push plate 31, the clamping plate 27 can rotate around the axis of the fixing column 34, and the connecting spring 23 is stretched, so that the upper part of the clamping plate 27 can come out of the arc groove 28 and gradually approach the surface of the metal bar, so that metal bars of different diameters can be fixed in the arc base 4, avoiding the situation that the cutting position is offset due to the shaking of the metal bar when the cutting mechanism cuts it, and ensuring the stable cutting work.

[0026] Working principle: when the metal bar rolls down from the tilting table 6, the top of the clamping plate 27 will not protrude in the arc groove 28, so that the two ends of the metal bar can be respectively located in the arc base 4, and then the rotating motor third 29 drives the bidirectional threaded rod 32 inside the arc base 4 to rotate, so that the two threaded sliders 30 on its surface are separated, and at the same time, the two push plates 31 on its top are synchronously driven to separate from each other, and the bottom end of the clamping plate 27 is lower than the top of the push plate 31, so that the outer walls of one side of the two push plates 31 that are separated from each other will contact the bottom end of the clamping plate 27, with the movement of the push plate 31, the clamping plate 27 can rotate around the axis of the fixed column 34, and at the same time, the connecting spring second 33 is stretched, so that the upper part of the clamping plate 27 can come out of the arc groove 28 and gradually approach the surface of the metal bar, so that metal bars of different diameters can be fixed in the arc base 4, avoiding the situation that the cutting position is offset due to the shaking of the metal bar when the cutting mechanism cuts it, and ensuring the stable cutting work.

When the vertical plate 17 drives the inclined plate 16 to move downward, the inclined plate 2 35 in the notch 37 at the bottom end of the inclined plate 17 will contact the upper surface of the metal bar away from the baffle plate 7. Because the cross-section of the metal bar is circular, and the notch 37 is fixedly connected with the baffle plate 2 41 closely attached to the inclined plate 2 35, as the inclined plate 16 continues to move downward, the inclined plate 2 35 is subjected to the extrusion force, which will cause the inclined plate 16 and the inclined plate 2 35 to deflect together, and then continue to slide downward along the surface of the metal bar.

[0029] Working principle: when the vertical plate 17 drives the inclined plate 16 to move downward, the inclined plate 2 35 in the notch 37 at the bottom end of the inclined plate 17 will contact the upper surface of the metal bar away from the baffle plate 7. Because the cross-section of the metal bar is circular, and the notch 37 is fixedly connected with a baffle 2 41 that is closely attached to the inclined plate 2 35, as the inclined plate 16 continues to move downward, the inclined plate 2 35 is subjected to an extrusion force, which will cause the inclined plate 16 and the inclined plate 2 35 to deflect together, and then continue to slide downward along the surface of the metal bar until the inclined plate 3 40 on the rotating shaft 36 contacts the surface of the metal bar, which will cause the inclined plate 3 40 to be subjected to a pressing force, causing its compression connecting spring 39 to deflect toward the baffle 1 38, thereby driving the rotating shaft 36 to rotate, causing the inclined plate 2 35 to deflect toward the surface of the metal bar, so that the inclined plate 2 35 is located in the gap between the two adjacent metal bars, ensuring that they can be separated, avoiding the situation where the separation cannot be caused by the smaller diameter of the adjacent metal bar.
