DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-7 , the present utility model provides a technical solution: a disposable guide wire cutting device, including a cutting table 1, on which a plurality of first wedge-shaped grooves 11 and second wedge-shaped grooves 12 are equidistantly arranged, and the first wedge-shaped grooves 11 and the second wedge-shaped grooves 12 are arranged alternately. Inside the first wedge-shaped grooves 11 and the second wedge-shaped grooves 12, lead screws 2 are rotatably connected, and worm gears 21 are fixedly connected to the ends of the lead screws 2;
[0023] In the first wedge-shaped grooves 11 and the second wedge-shaped grooves 12, wedge blocks 3 threadedly connected to the lead screws 2 are provided, and lifting columns 31 are fixedly connected to the middle parts of the upper ends of the wedge blocks 3;
[0024] A servo motor 4 is installed on the upper end of the cutting table 1. Two driving belt pulleys 41 are fixedly connected to the output shaft of the servo motor 4. On both side walls of the two ends of the cutting table 1, rotating shafts 5 are rotatably connected through bearing seats, and a plurality of worm parts 51 are equidistantly arranged on the rotating shafts 5. The worm parts 51 are correspondingly meshed with the worm gears 21. One end of each rotating shaft 5 is fixedly connected with a driven belt pulley 52, and the driven belt pulleys 52 are respectively connected to the corresponding driving belt pulleys 41 through belts 53;
[0025] Hydraulic cylinders 6 are installed at both ends of the cutting table 1, and push plates 7 are connected to the ends of the piston rods of the hydraulic cylinders 6. A plurality of cutting knives 71 are equidistantly arranged on the push plates 7.
[0026] Further, a limiting groove 311 is provided on the side wall of the lifting column 31, and a cutting groove 312 is provided at the position of the limiting groove 311. The cutting knives 71 are respectively opposite to the corresponding cutting grooves 312. When the lifting column 31 moves, it straightens the guide wire. The guide wire is limited and straightened through the limiting groove 311 to ensure that the lengths of the guide wire segments between adjacent lifting columns 31 are the same, which is convenient for the next step of one-time equidistant cutting of the guide wire; the cutting groove 312 allows the cutting knife 71 to push in and cut the guide wire.
[0027] Further, L-shaped plates 8 are provided on the side walls of the lifting columns 31 at both ends, and locking bolts 9 are threadedly connected to the vertical plates of the L-shaped plates 8. The locking bolts 9 are opposite to the limiting grooves 311. Here, the lifting columns 31 are located on the first wedge-shaped grooves 11 at the head and tail ends. The locking bolts 9 on the lifting columns 31 at the head and tail ends lock and limit the head and tail of the guide wire, so that all the lifting columns 31 can move to straighten the guide wire, and the lengths of the guide wire segments between adjacent lifting columns 31 are the same.
[0028] Furthermore, a rubber pad is provided at the end of the locking bolt 9. During the process of locking the guide wire, the rubber pad can prevent damage to the guide wire.
[0029] Furthermore, the thread helix direction of the lead screw 2 in the first wedge-shaped groove 11 is opposite to that of the lead screw 2 in the second wedge-shaped groove 12. The driving pulley 41 drives the rotating shaft 5 to rotate synchronously and in the same direction through the belt 53. Then, the worm part 51 drives the worm wheel 21 to rotate synchronously and in the same direction. Due to the opposite thread helix directions of the lead screw 2, the wedge blocks 3 on the first wedge-shaped groove 11 and the second wedge-shaped groove 12 move towards each other.
[0030] Specifically, first, the head and tail ends of the guide wire are locked by the locking bolt 9 on the head and tail position lifting columns 31, and the guide wire is placed in the limiting groove 311. The guide wire covers half of the limiting groove 311. Then, the guide wire is wound around the lifting column 31 and is correspondingly clamped in the limiting groove 311. Then, the power supply is connected to start the servo motor 4 to drive the driving pulley 41 to rotate. The driving pulley 41 drives the rotating shaft 5 to rotate synchronously and in the same direction through the belt 53. Due to the meshing of the worm part 51 and the worm wheel 21, the lead screw 2 is driven to rotate synchronously. Since the thread helix direction of the lead screw 2 in the first wedge-shaped groove 11 is opposite to that of the lead screw 2 in the second wedge-shaped groove 12, the wedge blocks 3 on the first wedge-shaped groove 11 and the second wedge-shaped groove 12 move towards each other. Then, the guide wire is straightened by the movement of the lifting column 31, ensuring that the lengths of the guide wire segments between adjacent lifting columns 31 are the same. Then, the hydraulic cylinder 6 is started to push the cutting knife 71 to move to cut the bent part of the guide wire at equal intervals at one time, ensuring the cutting efficiency of the guide wire.
[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
