[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 The utility model provides an embodiment: a cutting device for the production of steel-plastic conversion parts, including a base 1. The base 1 serves as the basic support part of the entire device and is usually made of a solid metal material with a large weight and a stable structure. The top of the base 1 is slidably connected to a fixed plate 2. The fixed plate 2 is usually a flat plate structure made of steel with high strength and rigidity. The function of the fixed plate 2 is to fix the clamping structure of the raw material and provide an installation basis for its installation. The top of the base 1 is fixedly connected to a guide rail frame 3. The guide rail frame 3 is generally welded to the top of the base 1 by steel and has high strength and stability. A guide hole is provided inside to guide the sliding during processing. The inside of the guide rail frame 3 is slidably connected to a pipe 4, which is made of two materials, steel and plastic. The shape of the pipe 4 is generally cylindrical, and its outer diameter and inner diameter vary according to different usage requirements.

[0032] Reference Figure 1 and Figure 3The front side of the fixed plate 2 is fixedly connected to a conduit 8. Conduit 8 is typically a cylindrical tubular structure made of stainless steel. It serves to install and guide subsequent components, ensuring stable movement during operation. A hydraulic rod 9 is fixedly connected to the interior of conduit 8. The hydraulic rod 9 operates by using the pressure of hydraulic oil to push a piston, which in turn drives the piston rod out. The hydraulic rod 9 has the advantages of large thrust, fast speed and good stability, and can meet the requirements of fixing the pipe 4 during the cutting process of steel-plastic conversion parts. The internal sliding connection of the conduit 8 is connected with a sliding rod 10. The function of the sliding rod 10 is to slide forward under the push of the hydraulic rod 9, driving other structures to rotate, and then driving the internal support movement. The external rotation connection of the sliding rod 10 is connected with multiple rotating plates 2 12. The function of the rotating plate 2 12 is to rotate under the drive of the sliding rod 10, thereby pushing the internal support structure to produce relative movement, thereby realizing the internal support fixation of the pipe 4. The external rotation connection of the conduit 8 is connected with multiple rotating plates 11. The function of the rotating plate 11 is to pull the rest of the internal support plate 13 at the bottom to move, and cooperate with the rotating plate 2 12 to jointly realize the expansion and contraction of the internal support structure. The external rotation connection of the multiple rotating plates 11 is connected with multiple internal support plates 13. The internal support plate 13 is an arc-shaped plate structure made of metal material. The function of the internal support plate 13 is to generate a supporting fixing force from the inside of the pipe 4 to ensure that the pipe 4 remains stable during the cutting process. A rotating assembly is provided on the top of the base 1 for quantitatively pushing the fixed plate 2 to slide. The adjacent sides of the multiple rotating plates 12 are respectively rotatably connected to the adjacent sides of the multiple inner support plates 13. The rotating connection between the rotating plate 12 and the inner support plate 13 gives the inner support plate 13 power to open. The driving end of the hydraulic rod 9 is fixedly connected to the rear side of the sliding rod 10. The driving belt sliding rod 10 slides through the hydraulic rod 9, thereby driving the subsequent structure to rotate, open and clamp.

[0033] Reference Figures 1 to 2 The base 1 is internally fixedly connected to two electric push rods 5, whose main function is to provide power for linear motion, push the subsequent structure to move, and realize the rise and fall of the cutting structure. The driving ends of the two electric push rods 5 are fixedly connected to two sliding blocks 6. The sliding blocks 6 are generally rectangular in shape. Their main function is to carry the subsequent structure and slide inside the base 1 to adjust the position. The two sliding blocks 6 are internally rotatably connected to a cutting disk 7. The cutting disk 7 is usually a circular sheet structure made of high-strength alloy steel. Its edge has sharp serrations and is used for cutting steel-plastic conversion parts. The external sliding of the two sliding blocks 6 is connected to the inside of the base 1. The sliding of the sliding blocks 6 drives the cutting disk 7 to slide up and down to produce the cutting movement, which completely cuts the steel-plastic conversion part. The external sliding of the cutting disk 7 is connected to the inside of the base 1.

[0034] Reference Figure 1 and Figure 4The rotating assembly includes a protective shell 14. The bottom of the protective shell 14 is fixedly connected to the top of the base 1. The protective shell 14 is firmly connected to the base 1 by welding to protect the internal intermittent pushing assembly from being affected by the outside world. The rear side of the protective shell 14 is fixedly connected to a motor 15, whose main function is to provide power to drive the subsequent structure to rotate, thereby producing an intermittent feeding effect. The driving end of the motor 15 is fixedly connected to a half gear 16. The function of the half gear 16 is to intermittently engage with the subsequent structure to produce an intermittent rotation effect. The internal rotation of the protective shell 14 is connected to a gear 2 17. The front side of the gear 2 17 is fixedly connected to a convex button 18. The intermittent rotation of the gear 2 17 drives the cam 18 to produce an eccentric circular motion, which drives the subsequent structure to generate a pushing force. The rear side of the fixed plate 2 is fixedly connected to a connecting rod 20. The connecting rod 20 is used to push the fixed plate 2 to slide and push the feeding. The rear side of the connecting rod 20 is fixed. A motion groove 19 is fixedly connected, and a movable groove is opened in the middle of the motion groove 19 for the convex button 18 to slide back and forth inside. The outside of the half gear 16 is meshed with the outside of the gear 2 17. This meshing transmission method enables the power of the motor 15 to be transmitted to the gear 2 17 through the half gear 16, thereby realizing the intermittent rotation of the gear 2 17. The inside of the motion groove 19 is in contact with the outside of the convex button 18. This contact method enables the convex button to slide inside the motion groove 19 and push the motion groove 19 to move linearly when the gear 2 17 rotates.

[0035] Working principle: First, the worker slides the pipe 4 from the inside of the guide frame 3 to the rear side to contact the front side of the fixed plate 2, and then turns on the switch of the hydraulic rod 9. The driving end pushes the internal sliding rod 10 to slide forward, thereby driving multiple rotating plates 12 to rotate, and then driving multiple inner support plates 13 to produce relative movement, and the bottom rotating plate 11 pulls the rest of the inner support plate 13 to move, stretching out multiple inner support plates 13, and generating a fixing force from the inside of the pipe 4 to stretch it out. By rotating and stretching, it can adapt to a variety of pipes 4 with different inner diameters, greatly improving the versatility and flexibility of the equipment, and reducing the trouble of changing equipment due to different specifications of the pipe 4. Moreover, the fixing method of stretching from the inside is more stable and reliable, which can effectively prevent the pipe 4 from displacement or shaking during processing or transportation, ensuring the safety and accuracy of operation.

[0036] Secondly, by turning on the switch of the motor 15, its driving end drives the internal half gear 16 to rotate, and through the meshing connection with the gear 2 17, drives the gear 2 17 to rotate in a gap, thereby driving the convex button 18 to produce a circular motion, and then pushes the motion groove 19 to slide forward, driving the connecting rod 20 to push the fixed plate 2 to slide forward, and the intermittent rotation of the gear 2 17 realizes the intermittent sliding of the pipe 4, and then realizes the effect of automatically pushing the pipe 4 to slide for cutting at a fixed distance. The intermittent rotation can accurately control the sliding distance of the pipe 4, ensure the accuracy and consistency of the cutting, and improve product quality.

[0037] Finally, the driving ends of the two electric push rods 5 inside the base 1 rise and push the two electric push rods 5 to slide upward, thereby driving the cutting disk 7 with its own power supply to rotate at high speed to cut the top pipe 4. The rise and fall of the electric push rods 5 are coordinated with the quantitative pushing mechanism at the top to form an automated cutting effect, reduce manual intervention, and improve cutting accuracy and cutting efficiency.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
