Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a sealing element cutting equipment. Background Art

[0002] Seals are materials or parts that prevent fluids or solid particles from leaking between adjacent joint surfaces and prevent external impurities such as dust and moisture from invading the internal parts of machinery and equipment. The storage room temperature of seals is preferably below 30°C to avoid high-temperature aging of the seals. When cutting existing seals, the elastic sleeve of the seal is generally used to fit on the support shaft, and then the cutter is used to cut at equal distances.

[0003] After searching the Chinese patent with publication number CN219726338U, a seal cutting device is disclosed. The first motor is set to drive the connecting frame to rotate, and then the positions of the two groups of support rods are adjusted by the rotation of the connecting frame. Then, when the seals on one group of support rods are being cut, the seals can be put on the other group of support rods and wait. Then, after cutting, it can be directly rotated to place the seals to be cut in the cutting position, avoiding downtime and waiting. At the same time, the support rods in the cutting position can be driven by the second motor, the square rods and the square holes on the connecting parts. At the same time, the position of the second motor can be adjusted by using the sliding U-shaped frame, the push block and the magnetic strip, thereby facilitating the separation of the square rods and the connecting parts without affecting the position adjustment of the support rods, thereby avoiding the downtime and waiting process.

[0004] Based on the above search and combined with the prior art, it is found that the above patent has certain defects. When rotating and replacing the support rod, it is still necessary to adjust the position of the second motor through the sliding U-shaped frame, push block and magnetic strip to control the connection between the square rod and the connecting part. The operation is still relatively cumbersome, and the connection of the support rod structure cannot be completed directly during the support rod replacement process. It takes a long time and is costly, which reduces the cutting efficiency of the seal. Utility Model Content

[0025] Furthermore, the arc blocks 15 are adapted to the size of the arc groove 2 14, the arc groove 1 11 is adapted to the size of the fixed rod 13 and the transmission rod 16, the four corners of the outer wall on one side of the sliding plate 7 are fixedly connected with the telescopic rod 9, one end of the piston rod of the telescopic rod 9 is fixedly connected to the inner wall of the rectangular groove, and the arc blocks, arc groove 1 and arc groove 2 are all on the same straight line with the center of rotation of the movable plate.

[0026] Furthermore, the outer wall of the telescopic rod 9 is sleeved with a spring 12, and the two ends of the spring 12 are fixedly connected to the movable plate 5 and the telescopic rod 9 respectively. Two limit grooves 6 are provided on the outer walls on both sides of the other side of the movable plate 5, and the limit grooves 6 are respectively located on both sides of the arc groove 11. The limit grooves 6 and the limit blocks 17 are both hemispherical, and the limit blocks 17 are adapted to the size of the limit grooves 6. The inner walls on the other side of the top and bottom of the cutting frame 1 are fixedly connected to the fixed plates 2, and the outer walls of one side of the fixed plates 2 are fixedly connected to the limit plates 3, and the limit plates 3 are adapted to the position of the support rods 4. The limit plates 3 connected to the cutting frame 1 through the fixed plates 2 limit the support rods 4 during the rotation and cutting process, so that the connected seals are not easy to fall off, and after rotating to the outside, they are separated from the limit plates 3 for convenient loading and unloading.

[0027] Working principle: During the cutting process of the seal, when the support rod 4 on which the seal is placed is replaced alternately, the motor 8 is started, and the motor 8 drives the movable plate 5 to rotate 180 degrees, so that the support rod 4 that has been cut is rotated to the outside, and the support rod 4 that has not been cut is rotated to the inside for cutting again. When the movable plate 5 is horizontal, the limit block 17 on the sliding plate 7 is inserted into the limit groove 6 of the movable plate 5 for positioning. At this time, the arc block 15 on the transmission rod 16 connected to the output shaft of the motor 2 10 is inserted into the arc groove 2 14 of the fixed rod 13. When the motor 2 10 is started, the fixed rod 13 and the support rod 4 can be driven to rotate by the arc block 15, so as to control the seal to cooperate with the cutter for cutting, and the movable plate 5 is horizontal. When the plate 5 rotates, the limit block 17 is first separated from the limit groove 6, and the sliding plate 7 slides backward first. After the movable plate 5 is removed, the sliding plate 7 is reset under the action of the telescopic rod 9 and the spring 12. When the replaced support rod 4 rotates to the sliding plate 7 position, the limit block 17 is pressed again. After the movable plate 5 is horizontal again, the limit block 17 is again stuck in the inner wall of the limit groove 6, and the arc block 15 enters the arc groove 2 14 on the fixed rod 13 connected to the replaced support rod 4 again, and the alternating replacement of the support rod 4 is directly completed. The limit plate 3 connected to the fixed plate 2 on the cutting frame 1 limits the support rod 4 during rotation and cutting, so that the connected seal is not easy to fall off. After rotating to the outside, it is separated from the limit plate 3 for convenient loading and unloading.
