DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figures 1 to 5 A cutting device for processing a sealing ring comprises: a base 1, a cutting frame 11 is installed on the upper end of the base 1; a lifting mechanism 2 is installed on the cutting frame 11, and is used to drive a cutting knife 12 and a cutting knife 2 13 to rise and fall; a connecting mechanism 3 is installed at the lower end of the lifting mechanism 2, and is used to install the cutting knife 12 and the cutting knife 2 13; a separating mechanism 1 4 is installed at the lower end of the connecting mechanism 3, and is used to separate the cutting completed sealing ring from the cutting knife 12 and the cutting knife 2 13; a separating mechanism 2 5 is installed at the lower end of the connecting mechanism 3, and is used to separate the raw material in the cutting knife 12 from the cutting knife 12.

[0024] The working principle of the utility model is as follows: when in use, the cutting knife 12 and the cutting knife 2 13 are installed to the lower end of the lifting mechanism 2 through the connecting mechanism 3, and then the raw material is placed on the base 1. Then, the cutting knife 12 and the cutting knife 2 13 are pushed downward by the lifting mechanism 2 to punch and cut the raw material. Then, the cutting sealing ring and the excess raw material can be separated from the cutting tool through the separating mechanism 1 4 and the separating mechanism 2 5. The cutting work of the sealing ring can be completed at one time, and no manual separation is required, which can effectively improve the processing efficiency and better meet the use requirements.

[0025] As a further solution, the lifting mechanism 2 includes a lifting electric push rod 21 installed on the upper end of the cutting frame 11, the telescopic end of the lifting electric push rod 21 passes through the cutting frame 11 and is fixed with a lifting seat 23, and a lifting guide rod 22 is also slidably inserted on the cutting frame 11, and the lower end of the lifting guide rod 22 is fixedly connected to the upper end of the lifting seat 23.

[0026] The working principle of the lifting mechanism 2 is: by pushing the lifting seat 23 downward through the lifting electric push rod 21, the cutting knife 12 and the cutting knife 2 13 below the lifting seat 23 can be moved downward, and the raw materials on the base 1 can be punched and sheared.

[0027] As a further solution, the connecting mechanism 3 includes a mounting seat 231 installed at the lower end of the lifting seat 23 and a connecting seat 31 installed at the upper ends of the cutting blade 12 and the cutting blade 2 13. The connecting seat 31 is inserted at the lower end of the mounting seat 231. A connecting positioning hole 32 is also provided on the connecting seat 31. Connecting grooves 36 are provided at positions corresponding to the connecting positioning holes 32 on both sides of the mounting seat 231. Buckle grooves 37 are also provided at positions corresponding to the connecting grooves 36 on both sides of the mounting seat 231. A connecting buckle plate 35 is installed in the buckle groove 37. A connecting buckle plate 35 is slidably inserted in the connecting groove 36. A connecting rod 33, one end of which is fixed with a connecting positioning pin 39, the end of which extends into the connecting positioning hole 32, the other end of which passes through a connecting buckle plate 35 and is threadedly screwed with a connecting end cover 34, a connecting spring 38 is also mounted on the connecting rod 33, the two ends of which are respectively connected to the connecting positioning pin 39 and the connecting buckle plate 35. In the present embodiment, the cutting knife 12 and the cutting knife 2 13 are both annular blades, and a connecting chamfer 311 is also provided at the upper end of the connecting seat 31 for the convenience of installation.

[0028] The working principle of the connecting mechanism 3 is: during installation, pull the connecting end covers 34 on both sides to move outward, so that the connecting positioning pins 39 at the ends of the connecting rods 33 on both sides enter the connecting grooves 36. At this time, the connecting springs 38 are compressed. Then, the connecting seat 31 is inserted into the slot at the lower end of the mounting seat 231. Then, the connecting end covers 34 are loosened. Under the action of the connecting springs 38, the connecting positioning pins 39 are pushed to insert into the connecting positioning holes 32 on the connecting seat 31 to complete the fixing work. The operation is simple and the disassembly is convenient, so as to facilitate the replacement of different types of cutting tools for processing, which can better meet the use requirements.

[0029] As a further solution, the separation mechanism 4 includes multiple sets of separation telescopic rods 42 installed at the lower end of the connecting seat 31, and the telescopic ends of the separation telescopic rods 42 are fixed with separation plates 41. The separation telescopic rods 42 are also provided with separation springs 43. The two ends of the separation springs 43 are respectively connected to the separation plates 41 and the corresponding sides of the connecting seat 31. The separation mechanism 4 is located between the cutting knives 12 and 13.

[0030] The working principle of the separation mechanism 4 is as follows: during cutting, the lifting electric push rod 21 pushes the cutting blade 12 and the cutting blade 2 13 to move downward. When the separation plate 41 contacts the raw material, as the lifting electric push rod 21 continues to extend, the separation telescopic rod 41 contracts, and the separation spring 43 is compressed. The cut sealing ring enters the gap between the cutting blade 12 and the cutting blade 2 13. When the lifting electric push rod 21 is reset, the separation spring 43 recovers and pushes the separation plate 41 downward to push the sealing ring out, thereby realizing the rapid separation of the sealing ring and the tool. No manual operation is required, which can effectively improve the processing efficiency.

[0031] As a further solution, the separation mechanism 2 5 includes multiple groups of separation telescopic rods 2 52 installed at the lower end of the connecting seat 31, and the telescopic ends of the separation telescopic rods 2 52 are fixed with separation plates 2 51. The separation telescopic rods 2 52 are also provided with separation springs 2 53, and the two ends of the separation springs 2 53 are respectively connected to the separation plate 2 51 and the corresponding side of the connecting seat 31.

[0032] The working principle of the separation mechanism 25 is as follows: as the lifting electric push rod 21 pushes the cutting knife 13 to move downward, when cutting is completed, the cut material enters the cutting knife 13, the separation telescopic rod 52 contracts, and the separation spring 2 53 is compressed. When the lifting electric push rod 21 moves upward, it can drive the cutting knife 13 to move upward and separate it from the base 1. At this time, the separation spring 2 53 is reset and pushes the separation plate 2 51 to move downward, thereby pushing the material in the cutting knife 13 out, and the separation work of the raw material and the tool can be completed. There is no need for subsequent manual separation, which can improve the cutting efficiency.
