Description

Technical Field

[0001] The invention relates to the technical field of sealing ring trimming, in particular to automatic trimming equipment for sealing ring processing. Background Art

[0002] A sealing ring is a sealing element used to prevent leakage of liquid, gas or solid pollutants, and is widely used in machinery, automobiles, home appliances, etc. It is usually made of elastic materials (such as rubber, polyurethane, fluororubber, etc.) and achieves sealing function by pressing against the mating surface.

[0003] In the process of producing and processing sealing rings, trimming is an essential process. However, most factories still use manual trimming. This traditional method is not only labor-intensive but also inefficient, which seriously restricts the efficiency of production and processing. Workers need to maintain high concentration and fine operation for a long time to ensure the quality of trimming. However, due to the uncontrollability of human factors, this operation method often leads to errors and waste in the production process, thereby increasing production costs.

[0004] In order to improve production efficiency and quality and reduce human errors, many factories have begun to seek automated equipment to replace manual trimming. Automated trimming equipment can not only improve production efficiency, but also ensure the consistency and accuracy of trimming, thereby reducing scrap rate and production costs. By introducing advanced automation technology, factories can achieve higher production efficiency and better product quality, thus occupying a favorable position in the fierce market competition.

[0034] Working principle of the present invention:

[0035] Place the sealing ring that needs to be processed on the movable plate 2 to ensure that its position is accurate. Then, start the servo motor 3, which starts working and drives the screw 4 to rotate in a clockwise direction. During the rotation of the screw 4, since its thread cooperates with the thread of the movable block 5, the movable block 5 moves accordingly. During the movement of the movable block 5, it will drive the movable plate 2 fixed to it to move together until the movable plate 2 reaches the lower position of the inner ring cutting mechanism. At this time, start the cylinder 8, and the cylinder 8 will push the positioning plate 9 to move downward to achieve accurate positioning of the sealing ring on the movable plate 2. The function of the positioning plate 9 is to ensure that the sealing ring will not move during the cutting process, thereby ensuring the accuracy and quality of the cutting. After the positioning is completed, start the cylinder 2 10, and the cylinder 2 10 will drive the inner cutting knife 11 on the bracket 13 to move downward to accurately cut off the excess waste inside the sealing ring. After the cutting work is completed, the positioning Plate 1 9 and the inner cutting knife 11 will both move upward and reset to their initial positions. Then, the moving block 5 will drive the moving plate 2 to continue moving until the moving plate 2 reaches the lower position of the outer ring cutting mechanism. At this time, start the cylinder 3 16, and the cylinder 3 16 will push the positioning plate 2 17 to move downward, so as to achieve precise positioning of the sealing ring on the moving plate 2 to prevent movement during the cutting process. After the positioning is completed, start the cylinder 4 19, and the cylinder 4 19 will drive the outer cutting knife 18 on the bracket 2 20 to move downward, and accurately cut off the excess waste outside the sealing ring. After the cutting work is completed, the positioning plate 2 17 and the outer cutting knife 18 will both move upward and reset to their initial positions. Finally, the sealing ring is discharged through the opening 2 23 and the guide plate 26, and the opening 1 22 collects the excess waste inside the sealing ring to ensure the smoothness and efficiency of the entire processing process.
