Description

Technical Field

[0001] The utility model belongs to the technical field of metal processing, and in particular relates to a lug bending processing device on a locking washer. Background Art

[0002] Lock washers are a common fastener widely used in machinery, automobiles, aviation and other fields. Their main function is to prevent threaded connections from loosening under vibration or load changes. Lock washers usually need to have a certain elasticity and locking force to ensure the reliability of the connection.

[0003] In the prior art, the production of locking washers mostly adopts the traditional stamping process. This process usually includes multiple steps: first, the metal sheet is formed by preliminary stamping; then, through further processing steps, the edge of the washer is lug-processed to achieve the locking function. This multi-step processing method is not only inefficient, but also often requires the use of multiple equipments, resulting in increased production costs.

[0004] In addition, due to the repeated movement and positioning of materials during the processing, it is easy to cause low processing accuracy, affecting the quality of the final product. Especially in the process of forming the lugs, extremely high processing accuracy is required to ensure the locking effect. Traditional processing methods are difficult to meet the production needs of high efficiency and high quality. Utility Model Content

[0043] The working principle of the utility model is:

[0044] When in use, the connecting pipe 63 is connected to the telescopic head of the cylinder on the punching machine. During the punching process, the connecting head 6 will move downward under the push of the cylinder. When the bottom of the connecting head 6 contacts the top of the locking member 5, the raw material sheet of the locking washer located between the locking member 5 and the connecting head 6 will be punched and split;

[0045] During the segmentation process, the plate is segmented into discs by the cooperation of the connector 6 and the locking member 5, and the lug punch 61 and the lug groove 51 are used to simultaneously process and shape the lug of the locking washer.

[0046] As the connector 6 moves downward, the disc with lugs is processed into a ring with lugs under the cooperation of the top column 2 and the punch column 71;

[0047] This allows the lock washer with the lug to be formed in one stamping process, which not only reduces the stamping steps but also increases the processing rate of the lock washer.
