Description
Technical Field
[0001] The utility model relates to the technical field of nodular iron processing, and specifically relates to a nodular iron surplus material cutter. Background Technique
[0002] Nodular iron is a cast iron alloy containing carbon and silicon, usually having high toughness and wear resistance, and is widely used in the manufacture of mechanical parts, especially parts that need to withstand high pressure and impact. Through a surplus material cutter, precise cutting and processing are carried out on nodular iron materials to remove unnecessary surplus material parts. However, during the process of removing surplus materials, using a fixing device can reduce accidents caused by the movement or instability of nodular iron, ensuring the safety of operators and equipment;
[0003] Traditional nodular iron surplus material cutters usually ensure that the workpiece can be accurately placed and positioned before processing through positioning pins or positioning grooves. The positioning pins are usually protruding metal pins or columns on the fixture, and their diameters match the positioning holes of the workpiece. The positioning grooves are grooves or groove-shaped designs on the surface of the fixture, used to receive positioning protrusions or specific geometric shape parts on the workpiece;
[0004] Traditional nodular iron surplus material cutters have the following problems: The positioning pins and positioning grooves are usually designed for workpieces with specific shapes, so they may limit the processing ability of nodular iron surplus material cutters for workpieces with different shapes or sizes. Different positioning pins or positioning grooves are required to adapt to different nodular iron designs, reducing the versatility and flexibility of the equipment. For this reason, we propose a nodular iron surplus material cutter. Content of the Utility Model

[0023] Please refer to Figures 1-3 , this embodiment provides a technical solution: A nodular iron residue cutter, including legs 3, support rods 13 and fixing frames 10;
[0024] Outrigger 3: There are four of them, and the tops of the four outriggers 3 are fixedly connected to the lower surface of a housing 2. It also includes a single-chip microcomputer 1, which is arranged at the right end of the front side of the housing 2. The input end of the single-chip microcomputer 1 is electrically connected to an external power supply. A fixing mechanism 4 is arranged inside the housing 2, and the top of the fixing mechanism 4 extends to the outside of the upper surface of the housing 2. The fixing mechanism 4 includes a rubber pad 41, a clamping block 42, a rotating groove 43, a pulley 44, a trapezoidal column 45 and a screw 47. There are four rotating grooves 43, which are respectively opened on the upper surface of the housing 2. The inside of each rotating groove 43 is rotatably connected to a clamping block 42 through a pin shaft. Rubber pads 41 are arranged at the tops of the clamping blocks 42 on the side close to the center of the housing 2. The bottoms of the clamping blocks 42 are rotatably connected to pulleys 44 through pin shafts. The screw 47 is rotatably connected between the upper and lower inner walls of the housing 2. The middle part of the screw 47 is threadedly connected to a trapezoidal column 45. The outer surfaces of the trapezoidal column 45 are cooperatively installed with the pulleys 44. The support rod 13 and the placement plate 6 are both located inside the four clamping blocks 42. The fixing mechanism 4 also includes a limiting column 46 and a sliding hole 48. There are four limiting columns 46, which are respectively fixedly connected between the upper and lower inner walls of the housing 2. There are four sliding holes 48, which are respectively opened inside the trapezoidal column 45. The inner walls of the sliding holes 48 are slidably connected to the outer surfaces of the vertically adjacent limiting columns 46. The fixing mechanism 4 also includes a motor 49, which is installed on the lower surface of the housing 2 through bolts. The top of the output shaft of the motor 49 is fixedly connected to the bottom end of the screw 47. The input end of the motor 49 is electrically connected to the output end of the single-chip microcomputer 1. Place the nodular iron on the placement plate 6, and then control the operation of the motor 49 through the single-chip microcomputer 1. The rotation of the output shaft of the motor 49 drives the rotation of the screw 47. The screw 47, through the threaded connection with the trapezoidal column 45, makes the trapezoidal column 45 move up or down along the outer surface of the limiting column 46. When the trapezoidal column 45 moves to a certain position and contacts the pulley 44, an extrusion force will be generated, causing the pulley to gradually rotate, and then driving the clamping block 42 to rotate a certain angle around the pin shaft in the rotating groove 43. When the bottom end of the clamping block 42 rotates, the rubber pad 41 at its top gradually contacts the outer surface of the nodular iron workpiece, and the moving position of the trapezoidal column 45 can be adjusted according to the diameter of the nodular iron to control the contact degree between the pulley 44 and the trapezoidal column 45, so as to adjust the clamping force of the rubber pad 41 at the top of the clamping block 42 on the outer surface of the nodular iron, and can quickly and accurately adapt to nodular iron workpieces of different shapes or sizes;
[0025] Support rod 13: They are all fixedly connected to the middle part of the upper surface of the housing 2. The tops of the support rods 13 are fixedly connected to the lower surface of a placement plate 6. The support rod 13 and the placement plate 6 are both located inside the fixing mechanism 4;
[0026] Fixing bracket 10: It is fixedly connected to the rear end of the upper surface of the outer shell 2. A guiding chute 11 is provided inside the fixing bracket 10. An installation bracket 8 is slidably connected to the inner wall of the guiding chute 11. A rotating shaft 5 is rotatably connected between the left and right inner walls at the front end of the installation bracket 8. A cutting disc 7 is fixedly sleeved in the middle of the rotating shaft 5. It also includes a motor 12. The motor 12 is installed on the right side surface of the installation bracket 8 by bolts. The left end of the output shaft of the motor 12 is fixedly connected to the right end of the rotating shaft 5. The input end of the motor 12 is electrically connected to the output end of the single-chip microcomputer 1. It also includes a second motor 9 and a lead screw 14. The lead screw 14 is rotatably connected between the upper and lower inner walls of the guiding chute 11. The middle of the lead screw 14 is threadedly connected to the rear end of the installation bracket 8. The second motor 9 is installed on the top end of the fixing bracket 10 by bolts. The bottom end of the output shaft of the second motor 9 is fixedly connected to the top end of the lead screw 14. The input end of the second motor 9 is electrically connected to the output end of the single-chip microcomputer 1. After the ductile iron workpiece is fixed, the second motor 9 is controlled by the single-chip microcomputer 1 to operate. The output shaft of the second motor 9 drives the lead screw 14 to rotate. The lead screw 14, through the threaded connection with the rear end of the installation bracket 8, causes the installation bracket 8 to move downward along the inner wall of the guiding chute 11. As the installation bracket 8 descends, the single-chip microcomputer 1 simultaneously controls the motor 12 to operate. The output shaft of the motor 12 drives the rotating shaft 5 to rotate, and then drives the cutting disc 7 to rotate. However, through the gradual descent of the installation bracket 8, it can be ensured that the cutting disc 7 can effectively contact the remaining material part of the ductile iron and cut it off.
[0027] The working principle of a ductile iron remaining material cutting device provided by the present utility model is as follows: First, place the ductile iron on the placement plate 6, and then control the operation of the first motor 49 by the single-chip microcomputer 1. The output shaft of the first motor 49 rotates to drive the screw rod 47 to rotate. The screw rod 47, through the threaded connection with the trapezoidal column 45, causes the trapezoidal column 45 to move upward or downward along the outer surface of the limit post 46. When the trapezoidal column 45 moves to a certain position and contacts the pulley 44, an extrusion force will be generated, causing the pulley to gradually rotate, and then driving the clamping block 42 to rotate a certain angle around the pin shaft in the rotating groove 43. When the bottom end of the clamping block 42 rotates, the rubber pad 41 at its top gradually contacts the outer surface of the ductile iron workpiece, and the moving position of the trapezoidal column 45 can be adjusted according to the diameter of the ductile iron to control the contact degree between the pulley 44 and the trapezoidal column 45, so as to adjust the clamping force of the rubber pad 41 at the top of the clamping block 42 on the outer surface of the ductile iron, and it can quickly and accurately adapt to ductile iron workpieces of different shapes or sizes. After the ductile iron workpiece is fixed, the second motor 9 is controlled by the single-chip microcomputer 1 to operate. The output shaft of the second motor 9 drives the lead screw 14 to rotate. The lead screw 14, through the threaded connection with the rear end of the installation bracket 8, causes the installation bracket 8 to move downward along the inner wall of the guiding chute 11. As the installation bracket 8 descends, the single-chip microcomputer 1 simultaneously controls the motor 12 to operate. The output shaft of the motor 12 drives the rotating shaft 5 to rotate, and then drives the cutting disc 7 to rotate. However, through the gradual descent of the installation bracket 8, it can be ensured that the cutting disc 7 can effectively contact the remaining material part of the ductile iron and cut it off.
[0028] It should be noted that the specific model of the single-chip microcomputer 1 disclosed in the above embodiments is STM32F207VCT6. For the first motor 49 and the second motor 9, it is recommended to select YS8024, and for the motor 12, BMR-50 can be selected. The single-chip microcomputer 1 controls the operation of the first motor 49, the second motor 9 and the motor 12 by using the commonly used methods in the prior art.
