Description

Technical Field

[0001] This utility model relates to the field of bending die technology, and in particular to a bending die for a medical device closure component. Background Technology

[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes left and right columns, a worktable, and a slider. The slider is connected to the piston of the hydraulic cylinder and moves up and down along the guide rail fixed on the column. The lower die is fixed on the worktable, and the upper die is installed at the lower end of the slider. The hydraulic system provides power, and the electrical system gives instructions. Under the action of the hydraulic cylinder, the slider drives the upper die downward to close with the lower die to realize the bending of the plate.

[0003] Currently, when using traditional bending fixtures to process closures, thin plates usually need to be bent multiple times. However, after bending, when unloading the closure from the bending fixture, the upper mold and the closure need to be disassembled together to complete the unloading of the closure. After unloading, the upper mold needs to be reinstalled and fixed, which is time-consuming and labor-intensive, greatly reducing processing efficiency. In addition, frequent disassembly and assembly can also make the bending angle unstable.

[0004] A search revealed a patent, CN221620431U, which discloses a bending fixture for facilitating the unloading of closure components. The fixture includes a left mold frame and a right mold frame, with the bending fixture rotatably connected to the left mold frame and a stop block rotatably connected to the right mold frame. After bending, rotating the stop block and the bending fixture facilitates unloading. However, in practical use, it has been found that while this bending fixture solves the unloading problem of closure components to some extent, it requires rotating the fixture and fixing it with magnets. The structure is complex and still involves rotational movements, which is not conducive to rapid operation and can easily lead to positional shifts due to rotational errors, causing fluctuations in the bending angle. Utility Model Content

[0005] To address the problems of existing bending dies being time-consuming and labor-intensive to assemble and disassemble, and having unstable bending properties, this utility model provides a bending die for medical device closures. By sliding pressure strips on the left and right clamping blocks, after the closure is bent, the closure can be removed simply by pulling the pressure strips out of the pressure strip grooves. Then, the pressure strips are inserted back into the pressure strip grooves to prepare for the next bending operation.

[0006] This invention provides a bending die for a medical device closure, comprising a left clamping block and a right clamping block, which are fixedly installed on a bending machine and adapted to the bending position of the closure. It also includes a pressure strip, which is slidably disposed within the left and right clamping blocks, allowing the closure to be fixed by inserting the pressure strip or released by removing it. The sliding design of the pressure strip simplifies the operation process, eliminating the need for additional rotation or complex fixing devices, thereby improving work efficiency and reducing errors caused by improper operation, ensuring the accuracy of the bending angle.

[0007] Furthermore, the left and right clamping blocks each include a clamping block body and a bending groove. One end of the clamping block body is fixed to the bending machine, and the other end is provided with a bending groove, forming pressure strip fixing blocks on both sides of the bending groove. The pressure strip fixing blocks are used to accommodate the sliding trajectory of the pressure strip to ensure that the pressure strip remains stable during sliding and does not deviate from the predetermined path.

[0008] Furthermore, a groove is provided at the bottom of the pressure strip fixing block, and the pressure strip is a strip-shaped structure that slides within the groove. The size of the groove matches the pressure strip to ensure a tight fit during sliding, preventing loosening from affecting the bending effect of the closure.

[0009] Furthermore, the bottom surface of the pressure strip fixing block is inclined, and the pressure strip groove is opened on the inclined surface. The pressure strip, which is slidably set in the pressure strip groove, is flush with the inclined surface. This inclined surface is used to avoid the parts during the bending process.

[0010] Furthermore, the molding groove has a bottom, two opposing clamping surfaces, and an opening. The bottom is parallel to the inclined surface, and the two clamping surfaces are perpendicular to the inclined surface. The opening width of the molding groove is smaller than the width of the molding strip, allowing the molding strip to extend from both ends of the molding groove and be confined within it.

[0011] Furthermore, the two clamping surfaces are divided into an upper clamping surface and a lower clamping surface. A limiting protrusion is provided on the side of the lower clamping surface near the groove, and a limiting groove is provided on the pressure strip to match the limiting protrusion. The cooperation between the limiting protrusion and the limiting groove ensures that the pressure strip is stably placed in the pressure strip groove.

[0012] Furthermore, the limiting protrusion extends along the length of the pressure strip groove, and the contact surfaces of both the limiting protrusion and the limiting groove are rounded. The rounded corner design effectively reduces the friction between the two, thereby improving the smoothness of the pressure strip during sliding.

[0013] Furthermore, the top of the clamping block body is provided with a mounting tenon for riveting to the bending machine. The mounting tenon facilitates the secure fixing of the clamping block body to the bending machine with bolts.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a bending die for a medical device closure component. The die has a simple structure and achieves rapid unloading by inserting and removing pressure strips, eliminating the traditional steps of disassembling and assembling the die, significantly improving efficiency, simplifying operation, and ensuring stable bending angle.

[0016] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0017] The closure 8 includes a main body 81 and a bent portion 82. The preparation of the bent portion 82 requires multiple bends to form a frame structure. However, traditional molds require disassembly and reassembly after each bend to remove the closure 8, resulting in unstable bending angles and low efficiency. To simplify the operation and improve bending efficiency, a bending mold for medical device closures is designed, such as... Figure 1 As shown, it includes a left clamping block 1 and a right clamping block 2, which are fixedly installed on the bending machine and adapted to the bending part 82 position of the closure 8. It also includes a pressure strip 3, which is slidably disposed in the left clamping block 1 and the right clamping block 2, so that the closure 8 can be fixed by inserting the pressure strip 3 or released by removing the pressure strip 3.

[0018] like Figure 4 and 5As shown, when bending the closure 8, the left clamping block 1 and the right clamping block 2 are riveted to the bending machine according to the position of the bending part 82. A bending seat is set below the clamping blocks, and the surface of the bending seat has a groove that matches the bending angle of the bottom of the pressure strip 3. When the bending machine lowers the clamping blocks, the bottom of the pressure strip 3 engages with the groove on the surface of the bending seat, completing the bending operation of the bending part 82 placed between the pressure strip 3 and the bending seat. After bending, the closure 8 can be removed by directly pulling out the pressure strip 3 from the left clamping block 1 and the right clamping block 2 from both sides, without having to completely remove the bending mold. Then, the pressure strip 3 is put back in, ready for the next bending operation. Figure 5 As shown, it is not necessary to completely pull out the pressure strip 3; it is only necessary to pull it out until the closing part 8 can be removed. This not only makes the operation simple and ensures the stability of the bending angle, but also prevents parts from falling and getting damaged.

[0019] like Figure 2 and 3 As shown, the left clamping block 1 and the right clamping block 2 include a clamping block body and a bending groove 4. One end of the clamping block body is fixed to the bending machine, and the other end is provided with a bending groove 4, with pressure strip fixing blocks 5 formed on both sides of the bending groove 4. The side closer to the bending groove 4 is the inner pressure strip fixing block 5, and the side farther away from the bending groove 4 is the outer pressure strip fixing block 5, as shown. Figure 4 and 5 As shown, the width of the outer pressure strip fixing block is significantly larger than the width of the inner pressure strip fixing block 5. This design can enhance the stability of the pressure strip 8 in the semi-extracted state when the closure part 8 is removed, so that the pressure strip 8 will not fall off due to the gravity at the tail end.

[0020] To facilitate the installation and removal of the pressure strip 3, a pressure strip groove 6 is provided at the bottom of the pressure strip fixing block 5. The pressure strip 3 has a strip-shaped structure and is slidably disposed within the pressure strip groove 6. The pressure strip 3 can be inserted into or removed from the end of the pressure strip groove 6.

[0021] In order to avoid the main body 81 of the closure 8 during the bending process, the bottom surface of the pressure strip fixing block 5 is inclined, and the pressure strip groove 6 is opened on the inclined surface. When the bending part 82 is bent, the main body 81 rotates accordingly, and is limited when it rotates to the inclined surface, which also ensures the bending angle to a certain extent.

[0022] To limit the movement of the pressure strip 3, the pressure strip groove 6 has a bottom, two opposing clamping surfaces, and an opening. The bottom is parallel to the inclined surface, and the two clamping surfaces are perpendicular to the inclined surface. The limiting protrusion 61 extends along the length of the pressure strip groove 6, and the contact surfaces of the limiting protrusion and the limiting groove 31 are both rounded. During the sliding process of the pressure strip 3, the cooperation between the limiting protrusion 61 and the limiting groove 31 effectively prevents the pressure strip 3 from coming out of the groove. The rounded corners reduce friction and improve the smoothness of operation.

[0023] To facilitate adjustment of the clamping block body according to the position of the bent portion 82 on the closure 8, a mounting tenon 7 is provided on the top of the clamping block body for riveting to the bending machine. The mounting tenon 7 facilitates the secure fixing of the clamping block body to the bending machine with bolts.

[0024] The above description is illustrative only and not restrictive of this utility model. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all such modifications, variations or equivalents will fall within the protection scope of this utility model.
