[0002] The cutting device for processing raw materials of nut joint forgings is mainly used for precise cutting of raw materials for nut joint forgings. This device typically consists of a cutting head, a feeding system, a positioning device, and a control system. Through proper design, this cutting device can ensure that appropriate force is applied to the raw material during the cutting process to achieve efficient and rapid cutting.

[0003] During the cutting process, the cutting head can quickly and accurately cut the forging material, offering advantages such as rapid cutting, minimal heat-affected zone, and a smooth cut surface. The positioning device is designed to ensure that each piece of material remains in a stable position during cutting, thereby ensuring cutting accuracy and reducing errors in subsequent processing.

[0004] However, existing technologies have some shortcomings when cutting raw materials for forgings of mother-son joints. Specifically, current equipment often fails to effectively limit and fix the raw material during the cutting process. This deficiency may cause the raw material to shift during cutting, resulting in an uneven cut surface. This not only affects the processing quality but may also increase the difficulty and cost of subsequent processing. Therefore, the cutting device needs to be optimized in terms of raw material limiting and cutting methods to improve cutting accuracy and processing efficiency. Summary of the Invention

Then, the cutting component 8 is controlled to move downward on the surface of the guide component 5. When the cutting component 8 moves downward, it can be limited and guided by the auxiliary component 7, which makes the cutting process of the female connector forging material more stable and avoids the situation of random displacement of the female connector forging material and inconsistent cutting surface during cutting.

A transmission belt 667 is wound around the outer surfaces of the pulley 666 and the pulley 662.

[0037] Furthermore, the auxiliary component 7 includes two rectangular columns 71. The lower ends of the two rectangular columns 71 are fixedly connected to the upper ends of the first side platform 2 and the second side platform 3, respectively. The upper ends of the two rectangular columns 71 are fixedly connected to a cover plate 72. A sliding groove 73 is provided in the middle of the two rectangular columns 71 at their opposite ends. A sensing groove 74 is provided in the middle of the front side of the two rectangular columns 71 at their opposite ends.

[0038] Furthermore, the outer diameters of the two touch blocks 66 are respectively adapted to the inner diameters of the two sensing slots 74.

[0039] Furthermore, the cutting component 8 includes two threaded blocks 81, which are slidably connected to the inner surfaces of two slide grooves 54. Threaded rods 82 are rotatably connected to the top walls of both slide grooves 54. The outer surfaces of the two threaded rods 82 are threadedly connected to the inner surfaces of the two threaded blocks 81. Transmission plates 83 are fixedly connected to the front ends of both threaded blocks 81. Three rectangular slots arranged in a linear array are opened on the upper ends of both transmission plates 83. Limiting plates 84 are slidably connected to the inner surfaces of the three rectangular slots on the same side. The lower ends of the three limiting plates 84 on the left and the three limiting plates 84 on the right are fixedly connected to the upper ends of the side platform 2 and the side platform 3, respectively. Arc-shaped baffles 85 are fixedly connected to the middle of the front ends of both transmission plates 83. Protective plates 86 are fixedly connected to the front ends of both arc-shaped baffles 85.

[0040] Furthermore, the ends of the two protective plates 86 that are close to each other are slidably connected to the ends of the two rectangular columns 71 that are far from each other.

[0041] Furthermore, a rotating rod 861 is rotatably connected to the middle of the front end of each of the two limiting plates 84. The two rotating rods 861 are located inside the two arc-shaped baffles 85 respectively. The front ends of the two rotating rods 861 pass through the protective plate 86 on the same side. A concave ring 862 is fixedly connected to the front end of the outer surface of each of the two rotating rods 861. A cutting strip 863 is wrapped around the outer surface of the two concave rings 862. The cutting strip 863 is located inside the two protective plates 86. A second motor 864 is fixedly connected to the right side of the front end of the right protective plate 86. The output end of the second motor 864 is fixedly connected to the front end of the right rotating rod 861 via a coupling. The cutting strip 863 is located between the two sliding grooves 73.

[0042] Furthermore, a placement groove 871 is provided on the rear side of the middle left end of side platform 2, a placement groove 872 is provided on the rear side of the middle right end of side platform 3, and a placement groove 873 is provided on the rear side of the middle left end of concave platform 1, extending to its right end. Placement grooves 871, 872, and 873 are interconnected. A pulley 874 is rotatably connected to the right side of the bottom wall of placement groove 871 and the left side of the bottom wall of placement groove 872. A cylinder 875 is fixedly connected to the upper end of each of the two pulleys 874, and the upper ends of the two cylinders 875 respectively penetrate the side platform 2. The upper ends of the two cylinders 875 on the upper ends of the side platform 1 2 and the side platform 2 3 are respectively fixedly connected to the lower ends of the threaded rod 2 82 on the same side. The outer surfaces of the two pulleys 3 874 are wrapped with the transmission belt 2 876. The bottom wall of the placement groove 2 872 has an installation groove on the left side. The inner surface of the installation groove is fixedly connected to the motor 3 877. The output end of the motor 3 877 is fixedly connected to the lower end of the pulley 3 874 on the left side through a coupling. The transmission belt 2 876 is located in the cavity formed by the placement groove 1 871, the placement groove 2 872 and the placement groove 3 873.

[0043] In the process of using this solution, the raw material of the forged nut joint to be cut is first placed on the upper end of the concave table 1. Then, by operating the control console 4, the control console 4 controls the motor 664 to start. Then, the output end of the motor 664 drives the connecting rod fixedly connected to it to rotate through the coupling. When the connecting rod rotates, the pulley 666 fixedly connected to it also rotates. The outer surfaces of the pulley 666 and the pulley 662 are wound with the transmission belt 667. Under the transmission connection of the transmission belt 667, the pulley 662 can drive the threaded rod 661 to rotate.

[0044] Since both sliders 61 are threaded to the outer surface of the threaded rod 661 and both sliders 61 are slidably connected to the inner surface of the groove 57, when the threaded rod 661 rotates, the sliders 61 on both sides can move inward at the same time. Then, the two sliders 61 simultaneously drive the L-shaped plate 62 fixedly connected to its rear end to move inward on the outer surface of the extension platform 56. The two L-shaped plates 62 can simultaneously drive the arc-shaped clamp 63 fixedly connected to it to fit against the surface of the forging material of the mother-son joint, thereby realizing the limiting and fixing of the forging material of the mother-son joint.

[0045] At the same time, the two sliders 61 simultaneously drive the main board 64 fixedly connected to them to move closer to each other. When the two main boards 64 move closer to each other, the sub-board 65 fixedly connected to their front ends also moves accordingly. As can be seen from the above, the outer diameters of the two touch blocks 66 are respectively matched with the inner diameters of the two sensing slots 74. Therefore, the touch block 66 on the same side can enter the inner side of the sensing slot 74 on the same side as the sub-board 65 on the same side moves, and trigger the sensor installed in the inner cavity of the sensing slot 74.

[0046] When the sensors in the inner cavity of the two sensing slots 74 are triggered, the second motor 864 and the third motor 877 can be driven simultaneously. When the third motor 877 starts, its output end drives the pulley 874 fixedly connected to it to rotate through the coupling. The outer surfaces of the two pulleys 874 are wound with the second transmission belt 876. Under the transmission connection of the second transmission belt 876, the two pulleys 874 can rotate simultaneously on the bottom wall of the first placement slot 871 and the second placement slot 872. The two pulleys 874 drive the cylinder 875 fixedly connected to its upper end to rotate.

[0047] The upper end of the cylinder 875 on the same side is fixedly connected to the lower end of the threaded rod 82 on the same side, so the threaded rods 82 on both sides can rotate at the same time. When the threaded rods 82 on both sides rotate, the threaded block 81 connected to the threaded surface is slidably connected to the slide groove 54 on the same side. Under the limiting and guiding action of the slide groove 54 on the same side, the two threaded blocks 81 move downward at the same time.

[0048] When the two threaded blocks 81 move downward, they can simultaneously drive the transmission plate 83 fixedly connected to their rear end to move downward. The three limiting plates 84 on the same side can limit and guide the transmission plate 83 on the same side, so that when the transmission plate 83 moves downward, it can drive the arc-shaped baffle 85 fixedly connected to it to move downward.

[0049] The protective plate 86, which is fixedly connected to the arc-shaped baffle 85 on the same side, is slidably connected to the left and right ends of the rectangular column 71, respectively. Therefore, when the two protective plates 86 move downward, the rotating rod 861 and the concave ring 862 can move downward simultaneously. The middle part of the cutting strip 863, which is wrapped around the outer surface of the two concave rings 862, is located between the two rectangular columns 71. Therefore, after the motor 864 starts, when the rotating rod 861, which is fixedly connected to it, is driven to rotate through the coupling at its output end, the two concave rings 862 can rotate simultaneously, thereby driving the cutting strip 863. Therefore, when the cutting strip 863 moves downward, the raw material of the forged joint directly below it can be cut and processed.

[0050] The console 4 mentioned above is a conventional setting in the prior art. In this solution, it is only necessary to control the drive of motor 664. Its specific control method, circuit connection method and control method are all conventional designs, so this solution will not elaborate on them.

[0051] The sensors mentioned above are conventional settings in the prior art. In this solution, it is only necessary to ensure that when the two touch blocks 66 enter the sensing slots 74 on the same side, they can touch the sensors, so that the sensors can simultaneously send start signals to motor 2 864 and motor 3 877. The specific control methods, circuit connection methods and control methods are all conventional designs, so this solution will not elaborate on them in detail.

[0052] It should be noted that the specific installation methods, circuit connection methods, and control methods of the motor 664, motor 864, and motor 877 used in this invention are all conventional designs, and will not be described in detail in this invention.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
