A connecting ball is movably installed in the middle of the inner wall of the swing arm on both sides. A right-angle rod is fixedly connected to the outer wall of the connecting ball on both sides. The inner wall of the right-angle rod on both sides is hollow and a movable plate is slidably connected to the inner wall. A guide member is fixedly connected to the top of the movable plate on both sides.
[0008] Preferably, a rectangular groove is provided in the middle of the opposite side of the right-angle rods on both sides, the outer walls of the guide members on both sides are slidably connected to the inner walls of the rectangular grooves on both sides, a connecting spring is fixedly connected to the inner wall of the right-angle rods on both sides, the bottom end of the connecting springs on both sides is fixedly connected to the top end of the movable strips on both sides, and a roller is fixedly connected to the end of the movable strips on both sides away from the right-angle rods.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a raw material cutting device for machining. The cutting process of mechanical materials is synchronized. A blowing mechanism that can move along an arc trajectory to remove chips is set above the cutting platform. The arc trajectory blowing mechanism can be fully adapted to the arc characteristics of the workpiece. During the cutting process, chips are blown away in real time and from all directions to avoid chip accumulation at the cut or material surface, and to prevent it from affecting the stability of the electric arc or scratching the material. This ensures cutting accuracy and reduces rework caused by chip interference. It can be dynamically and flexibly adapted when cutting complex shaped materials.

During the chip removal action in the cutting process, the right-angle rods on both sides can drive the rollers on both sides to roll horizontally on the top of the material in a corresponding arc trajectory, and roll the two ends of the material to ensure that they are flush. This ensures that the material remains flat during the cutting process, thereby ensuring the straightness and parallelism of the cut, reducing problems such as arc fluctuation and slag on the cut caused by material deformation, and improving the processing accuracy of the final workpiece.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] like Figure 1 - Figure 3 and Figure 7As shown, a raw material cutting device for machining includes a cutting platform 1. Linear guide rails 2 are fixedly installed on both sides of the top of the cutting platform 1. A movable frame 3 is slidably connected to the top of the linear guide rails 2 on both sides. A driving component is provided on the outer wall of the movable frame 3. An adjustment component is provided on both sides of the outer wall of the cutting platform 1. A blowing component is provided in the middle of the cutting platform 1. The drive assembly includes a stepper motor 41, which is fixedly installed on the lower outer wall of the moving frame 3. A transmission gear 42 is fixedly connected to the drive end of the stepper motor 41. A rack 43 is fixedly connected to the top of the side of the cutting platform 1 near the transmission gear 42. The bottom of the transmission gear 42 is meshed with the top of the rack 43. A plasma cutting head 44 is slidably connected to the outer wall of the moving frame 3.
[0018] It should be noted that the material to be cut is first placed on the top of the cutting platform 1. The stepper motor 41 drives the transmission gear 42 to rotate in a forward and reverse cycle. Under the meshing transmission of the rack 43, the moving frame 3 can move back and forth along the top of the linear guide rails 2 on both sides. The outer wall of the moving frame 3 is equipped with a corresponding transmission structure that can drive the plasma cutting head 44 to move along the outer wall of the moving frame 3. At the same time, the moving frame 3 is equipped with a bolt structure that can adjust the vertical direction of the plasma cutting head 44, thereby realizing the movement adjustment of the plasma cutting head 44 in the X, Y, and Z directions of the raw material to be machined, flexibly adapting to the cutting requirements of the material.
[0019] like Figure 1 - Figure 6 As shown, the adjustment assembly includes a set of arc-shaped frames 51. Two arc-shaped frames 51 are fixedly connected to the outer walls of the cutting platform 1 on both sides. Sliding members 52 are slidably connected to the outer walls of both arc-shaped frames 51. A swing arm 53 is fixedly connected to the bottom of each sliding member 52. The end of each swing arm 53 away from the sliding member 52 is rotatably connected to the middle of the cutting platform 1. A dual-axis motor 54 is fixedly installed inside each sliding member 52. The dual-axis motor 54 can achieve 180-degree alternating forward and reverse rotation. Trigger gears 55 are fixedly connected to the drive ends of both sides of the dual-axis motor 54. The outer wall of the arc-shaped trajectory is evenly distributed with several teeth 513. The trigger gear 55 is meshed with the teeth 513. The inner wall of the two swing rods 53 is movably provided with connecting balls 56. The outer wall of the two connecting balls 56 is fixedly connected with right-angle rods 57. The inner wall of the two right-angle rods 57 is hollow and the inner wall is slidably connected with movable strips 58. The top of the two movable strips 58 is fixedly connected with guide members 59. The middle of the opposite side of the two right-angle rods 57 is provided with rectangular grooves 510. The outer wall of the two guide members 59 is slidably connected to the inner wall of the two rectangular grooves 510.
[0020] It should be noted that the dual-axis motors 54 on both sides drive the trigger gears 55 on both sides to rotate inside the sliding member 52, and the trigger gears 55 mesh with the teeth 513. Thus, during the rotation of the trigger gears 55, the sliding members 52 on both sides can slide along the outer wall of the arc frame 51 on both sides. The hinge rotation point of the swing rods 53 on both sides coincides with the center point of the cutting platform 1, further driving the swing rods 53 connected to the sliding member 52 on both sides to rotate on the inner wall of the arc frame 51 on both sides. During the rotation of the swing rods 53 on both sides, the right-angle rod 57 can be flexibly adapted to follow the movement of the swing rod 53 through the connecting ball 56. The movable strip 58 can move up and down flexibly on the inner wall of the right-angle rod 57. With the limiting assistance of the guide member 59 and the rectangular groove 510, the movement of the movable strip 58 is more stable.
[0021] like Figure 6 As shown, connecting springs 511 are fixedly connected to the inner walls of the right-angle rods 57 on both sides. The bottom ends of the connecting springs 511 on both sides are fixedly connected to the top ends of the movable plates 58 on both sides. Rollers 512 are fixedly connected to the ends of the movable plates 58 on both sides away from the right-angle rods 57.
[0022] It should be noted that as the swing arm 53 rotates, the distance between the sliding member 52 and the material on the cutting platform 1 also changes. This allows the roller 512 to exert a squeezing effect on the connecting spring 511 through the movable strip 58, thereby generating compression deformation and accumulating a certain amount of elastic potential energy. This enables the roller 512 to achieve flexible contact with the material surface. In the subsequent reverse rotation of the swing arm 53, the elastic potential energy is used to extend and release the roller 512, which means that the distance between the sliding member 52 and the material is flexibly adjusted during the rotation of the swing arm 53.
[0023] like Figure 1 and Figure 3 As shown, the purging assembly includes a jet pipe 61, with both ends of the jet pipe 61 fixedly connected to the middle of the two sliding members 52 respectively. A three-way pipe 62 is provided through the inside of the jet pipe 61. An air pump 63 is fixedly connected to the top of the jet pipe 61. The end of the three-way pipe 62 away from the jet pipe 61 is fixedly connected to the air outlet end of the air pump 63. An air inlet pipe 64 is fixedly connected to the air inlet end of the air pump 63.
[0024] It should be noted that the air pump 63 draws air from the outside through the air inlet pipe 64 and delivers it to the inside of the jet pipe 61 through the three-way pipe 62, and finally outputs it. The gas is blown onto the material surface on the cutting platform 1. The jet pipe 61 rotates and blows along the arc trajectory of the arc frame 51 with the sliding parts 52 on both sides, peeling off the debris and residues attached to the material during the cutting process.
[0025] like Figure 3As shown, a frame 66 is hinged to the outer wall of the cutting platform 1 on the side away from the stepper motor 41. An electric telescopic rod 65 is hinged to the outer wall of the cutting platform 1 below the frame 66. The drive end of the electric telescopic rod 65 is rotatably connected to the bottom of the frame 66.
[0026] It should be noted that the blowing direction of the jet pipe 61 is always maintained on the side from the stepper motor 41 toward the frame 66. During the blowing process, the debris on the surface of the material is concentrated and pushed into the interior of the frame 66. Finally, after the frame 66 is full, the electric telescopic rod 65 drives the frame 66 to flip downward at a certain angle, so that the debris can be concentrated and discharged.
[0027] like Figure 1 As shown, a control panel 7 is fixedly installed in the middle of the outer wall of the cutting platform 1. The control panel 7 is electrically connected to the stepper motor 41, the dual-axis motor 54, the air pump 63 and the electric telescopic rod 65.
[0028] The working principle of this utility model: First, the material to be cut is placed on the top of the cutting platform 1. The stepper motor 41 drives the transmission gear 42 to rotate in a forward and reverse cycle. Under the meshing transmission of the rack 43, the moving frame 3 can move back and forth along the top of the linear guide rails 2 on both sides. The outer wall of the moving frame 3 is equipped with a corresponding transmission structure that can drive the plasma cutting head 44 to move along the outer wall of the moving frame 3. At the same time, the moving frame 3 is equipped with a bolt structure that can adjust the vertical direction of the plasma cutting head 44, thereby realizing the movement adjustment of the plasma cutting head 44 in the X, Y, and Z directions of the machining raw material, flexibly adapting to the cutting requirements of the material. Next, the dual-axis motors 54 on both sides drive the trigger gears 55 on both sides to rotate inside the sliding member 52, and the trigger gears 55 mesh with the teeth 513. As the trigger gears 55 rotate, the sliding members 52 on both sides can slide along the outer wall of the arc frame 51 on both sides. The hinge rotation point of the swing rods 53 on both sides coincides with the center point of the cutting platform 1, which further drives the swing rods 53 connected to the sliding members 52 on both sides to rotate on the inner wall of the arc frame 51 on both sides. During the rotation of the two swing arms 53, the right-angle rod 57 can be flexibly adapted to follow the movement of the swing arm 53 through the connecting ball 56. The movable strip 58 can move up and down flexibly on the inner wall of the right-angle rod 57. With the limiting assistance of the guide 59 and the rectangular groove 510, the movement of the movable strip 58 is more stable. As the swing arm 53 rotates, the distance between the sliding member 52 and the material on the cutting platform 1 also changes. This allows the roller 512 to exert a squeezing effect on the connecting spring 511 through the movable strip 58, thereby generating compression deformation and accumulating a certain amount of elastic potential energy. This allows the roller 512 to achieve flexible contact with the material surface. In the subsequent reverse rotation of the swing arm 53, the elastic potential energy is used to extend and release the roller 512, which corresponds to the flexible adjustment of the distance between the sliding member 52 and the material during the rotation of the swing arm 53. During the rotation and swing of the two swing arms 53, the jet pipe 61 rotates synchronously. The air pump 63 draws air from the outside through the air inlet pipe 64 and delivers it to the inside of the jet pipe 61 through the three-way pipe 62, finally outputting the gas to blow on the material surface on the cutting platform 1. The jet pipe 61 rotates and blows along the arc trajectory of the arc frame 51 with the sliding parts 52 on both sides, peeling off the debris and residues attached to the material during the cutting process. The blowing direction of the jet pipe 61 is always maintained on the side from the stepper motor 41 toward the frame 66. During the blowing process, the debris on the material surface is concentrated and pushed into the inside of the frame 66. Finally, after the frame 66 is full, the electric telescopic rod 65 drives the frame 66 to flip downward at a certain angle, so that the debris can be concentrated and discharged.
