Abstract
Description
Technical Field
[0001] This utility model relates to the field of rivet processing tooling technology, specifically a tooling for cutting irregularly shaped materials for blind rivet lock rings. Background Technology
[0002] Aluminum alloy blind rivets are a newly developed product in China. Many experimental and testing measuring tools and fixtures are not readily available, so it is necessary to design the inspection fixtures and other tooling according to the design requirements of this newly developed product.
[0003] like Figure 1 As shown, an aluminum alloy blind rivet includes a core rod 100, a rivet sleeve 101, a drive washer 102, and a locking ring 103. The rivet sleeve and drive washer are fitted onto the core rod. The locking ring is located between the rivet sleeve and the core rod and is fitted onto the broken neck groove of the core rod. When the rivet sleeve is riveted at the end, its head has a small inner cavity. After the locking ring touches the drive washer, the locking ring is compressed and deformed into and fills the inner cavity, locking the core rod and the rivet sleeve to form a reliable connection. In the processing of the locking ring, the irregular material needs to be cut into blanks of appropriate length according to the required volume of the locking ring. Usually, the material is wire or sheet. The blanks are stamped, milled, heat-treated, and surface-treated to produce the finished locking ring. Among these processes, the blanking of the irregular material is an important production link, and its accuracy and efficiency directly affect the quality of the product and the production cost. There is no tooling for blanking the irregular material of the locking ring in the existing technology, and it is not easy to ensure the consistency of the blank length dimensions using the traditional wire cutting method. Utility Model Content

[0005] To solve the above problems, the technical solution adopted by this utility model is: a cutting tool for cutting irregularly shaped materials for blind rivet lock rings, including a base, a cutting blade, a positioning seat, a moving block, and a positioning block. The base is provided with multiple grooves of different specifications for passing through the irregularly shaped lock ring materials. The cutting blade is rotatably mounted on the side of the base and is provided with a cutting edge for cutting the material. The positioning seat is detachably mounted on the side of the base, forming a space between the positioning seat and the base for the cutting blade to pass through. A moving block is slidably mounted on the positioning seat, and the moving direction of the moving block is consistent with the direction of the grooves on the base. A positioning block for positioning the moving block is detachably mounted on the positioning seat. The positioning block is provided with a positioning screw that abuts against the moving block, and the positioning screw can adjust the distance between the moving block and the base.
[0006] Furthermore, the cutting blade is mounted on the base via a threaded rotating shaft, and the base is provided with a threaded hole that mates with the rotating shaft.
[0007] Furthermore, the positioning seat is mounted on the base by screws.
[0008] Furthermore, the base is provided with a limiting screw.
[0009] Furthermore, the movable block is narrower at the top and wider at the bottom, with a trapezoidal cross-section, and the positioning seat is provided with a sliding groove that cooperates with the movable block.
[0010] Furthermore, the positioning block is mounted on the base by screws.
[0011] Furthermore, the cutting sheet is provided with a handle on the side away from the rotation point, and the handle has a smooth shape.
[0012] The beneficial effects of this solution are as follows: Compared with the prior art, the cutting tool for irregular materials of pull rivet lock rings of this utility model is provided with a moving block and a positioning block. The positioning block is equipped with a positioning screw to adjust the distance between the moving block and the base. The irregular material of the lock ring is placed in the groove of the base. The cutting blade is pressed down to make it rotate. The blade of the cutting blade cuts the irregular material of the lock ring. The cut material is uniform in size and can process various specifications of irregular materials of lock rings. The tool has high durability and versatility. Attached Figure Description

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Implementation, for example, attached Figures 2 to 7 As shown: A cutting tool for cutting irregularly shaped materials for blind rivet lock rings includes a base 1, a cutting blade 2, a positioning seat 3, a moving block 4, and a positioning block 5. The base 1 has multiple grooves 11 of different sizes for the irregularly shaped lock ring material to pass through. The cutting blade 2 is rotatably mounted on the side of the base 1 and has blades 21 for cutting the material. The positioning seat 3 is detachably mounted on the side of the base 1, forming a space between the positioning seat 3 and the base 1 for the cutting blade 2 to pass through. The moving block 4 is slidably mounted on the positioning seat 3. The moving block 4 is narrower at the top and wider at the bottom, with a trapezoidal cross-section. The positioning seat 3 has... The sliding groove 31 cooperates with the moving block 4. The moving block 4 cannot move up and down, but can only slide along the direction of the sliding groove 31. The moving direction of the moving block 4 is consistent with the direction of the groove 11 on the base 1. The positioning base 3 is detachably equipped with a positioning block 5 for positioning the moving block 4. The positioning block 5 is provided with a positioning screw 6 that abuts against the moving block 4. The positioning screw 6 can adjust the distance between the moving block 4 and the base 1 to be consistent with the length of the required blank. The locking ring irregular material 8 passes through the groove 11 of the corresponding specification and abuts against the moving block 4. The cutting blade 2 is rotated to cut the material, so that the size and length of the cut material are uniform.
[0023] The cutting blade 2 is mounted on the base 1 via a threaded rotating shaft. The base 1 has a threaded hole that mates with the rotating shaft. When the cutting blade 2 rotates, it rotates around the rotating shaft as the center of rotation. The blade 21 of the cutting blade 2 is in close contact with the side of the base 1. The side of the cutting blade 2 away from the rotation point has a hand-held part 22. The hand-held part 22 has a smooth shape, which makes it easy to hold and operate the cutting blade 2 to rotate for feeding. The positioning seat 3 is mounted on the base 1 with screws. The positioning block 5 is mounted on the base 1 with screws for easy disassembly and installation. The base 1 has a limiting screw 7 to limit the rotation angle of the cutting blade 2 and prevent damage to the blade 21 of the cutting blade 2.
[0024] The specific implementation process is as follows:
[0025] Adjust the positioning screw 6 according to the required length of the lock ring blank, and then adjust the distance between the moving block 4 and the base 1. Pass the lock ring shaped material 8 through the groove 11 corresponding to its specification and abut against the moving block 4. Press down the cutting blade 2 to cut the lock ring shaped material 8. Repeat the cutting to obtain multiple blanks of uniform length. This tooling structure is simple and reliable, with high processing accuracy and consistency. It can cut lock ring shaped materials 8 of various specifications and has high versatility.
