Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a stamping device for screw production. Background Technology

[0002] A screw is a fastener consisting of a head and a shank. The head commonly comes in different shapes such as Phillips head, slotted head, and hex head. The shank has external threads and can be used with a nut or a hole with internal threads to connect and fix objects. In the production process, a stamping device can apply pressure to a metal sheet through a die, causing it to undergo plastic deformation or separation, thereby efficiently and accurately forming the screw head. This method not only has a fast production speed and high precision, but also allows for the mass production of screw heads with uniform specifications, meeting the needs of industrial production.

[0003] Chinese Patent Publication No. CN221603039U discloses a stamping device for screw production. Addressing the problem that existing stamping devices typically have fixed stamping dies, making disassembly inconvenient and preventing the replacement of different templates to produce screws of different specifications, the present invention proposes the following solution: It includes a stabilizing platform and a stamping template. The top of the stabilizing platform has a storage groove, and both sides of the storage groove have horizontal grooves on their inner walls. The stamping template is movably engaged within the horizontal grooves, and a positioning plate is slidably installed within the horizontal grooves. The stamping template also has slots on both sides. This utility model has a reasonable structural design. The fixed connection between the stabilizing platform and the stamping template is achieved through the cooperation of the positioning plate and the slots, as well as the cooperation of the positioning rod and the positioning grooves. This makes the stamping template and the stabilizing platform easy to install and disassemble, facilitating the replacement of different stamping templates to produce screws of different specifications, and ensuring high reliability.

[0004] Although the existing device facilitates the assembly and disassembly of the stamping template and the stabilizing platform, when reassembling the stamping template, the push handle and other components will automatically reset due to the spring elasticity. The operator needs to manually move the push handle upward to place the template into the storage slot. In actual operation, the operator needs to hold the template with one hand and operate the push handle with the other hand, which reduces the efficiency of stamping template replacement and affects production efficiency.

[0022] Please see Figures 1-4This utility model provides a stamping device for screw production, including a stabilizing platform 1, a stamping hydraulic rod 2 on the top of the stabilizing platform 1, and a stamping block 3 fixedly connected to the telescopic end of the stamping hydraulic rod 2; the stabilizing platform 1 has a placement cavity 4 inside, the placement cavity 4 is provided with a stamping template 5 and a fixing assembly, the fixing assembly including a positioning groove 401, a limiting slide groove 402, a bidirectional lead screw 403, a limiting slider 404, a pressing block 405, a positioning block 406 and a pressing groove 407, positioning... The groove 401 is opened at the bottom of the placement cavity 4, the limiting slide groove 402 is symmetrically distributed on the left and right sides of the placement cavity 4, the bidirectional lead screw 403 is rotatably connected to the bottom inner wall of the placement cavity 4, the limiting slider 404 is slidably connected inside the two limiting slide grooves 402, the pressing block 405 is fixedly connected to the side of the limiting slider 404 that is close to each other, the positioning block 406 is fixedly connected to the bottom of the stamping template 5, and the pressing groove 407 is symmetrically distributed on the left and right sides of the stamping template 5.

[0023] The stabilizing platform 1 serves as the basic support structure for the entire stamping device, providing a stable mounting platform for components such as the stamping hydraulic rod 2 and the placement cavity 4. This ensures the device remains stable during operation and prevents swaying from affecting stamping accuracy. The stamping hydraulic rod 2 drives the stamping block 3 through its telescopic end movement, providing stable and controllable stamping power for efficient stamping of screws. The stamping block 3 acts directly on the material to be processed, and its connection design with the stamping hydraulic rod 2 ensures precise pressure transmission, guaranteeing the quality of the stamping. The placement cavity 4 accommodates the stamping template 5, providing a specific working space for the stamping operation. In the fixing assembly, the positioning groove 401 and the positioning block at the bottom of the stamping template 5... The 406 mechanism enables precise positioning of the stamping template 5, ensuring its fixed position within the placement cavity 4 and preventing displacement. The limiting slide 402, in conjunction with the limiting slider 404, restricts the movement direction of the limiting slider 404, ensuring smooth sliding. The bidirectional lead screw 403, through rotation, drives the limiting slider 404 to move in opposite directions, thereby controlling the clamping and releasing of the pressing block 405 on the stamping template 5, facilitating quick replacement of the stamping template 5. The pressing block 405, in conjunction with the pressing groove 407 on the side of the stamping template 5, reliably clamps the stamping template 5, preventing template movement during stamping. The knob 9 allows operators to manually rotate the bidirectional lead screw 403, making operation convenient.

[0024] This invention, through the setting of fixed components, enables the rapid loading and unloading of the stamping template 5 and achieves automatic positioning of the positioning block 406, freeing up the workers' hands, greatly shortening the time for template replacement, and improving production efficiency. At the same time, the precise cooperation between the positioning groove 401 and the positioning block 406, and between the pressing groove 407 and the pressing block 405, ensures the accuracy of the installation position of the stamping template 5, thereby improving the precision and quality of screw stamping and reducing the scrap rate caused by template installation errors.

[0025] Specifically, such as Figure 1 As shown, the top of the stabilizing platform 1 is fixedly connected with uprights 10 in a rectangular array. The top of the uprights 10 is fixedly connected with a support plate 11. The lower part of the support plate 11 and the side surface of the uprights 10 are movably sleeved with a side extension plate 12. The stamping hydraulic rod 2 is set inside the support plate 11, and the stamping block 3 is set inside the side extension plate 12. The upright 10 and the support plate 11 form the upper frame structure of the stamping device, providing an installation foundation for the stamping hydraulic rod 2 and supporting and stabilizing the upper part of the entire device. The side extension plate 12 is movably sleeved on the side surface of the upright 10 and can move up and down within a certain range. It cooperates with the stamping block 3 to guide and protect the movement of the stamping block 3. At the same time, during the stamping process, the side extension plate 12 can help limit the movement trajectory of the stamping block 3, further improving the stamping accuracy. The stamping hydraulic rod 2 is installed in the support plate 11, which provides it with stable support and ensures the stability of the extension and retraction movement of the hydraulic rod. The stamping block 3 is located in the side extension plate 12. Through the guidance and protection of the side extension plate 12, the interference of external factors on the movement of the stamping block 3 is reduced, improving the accuracy and reliability of stamping.

[0026] Specifically, such as Figure 2 and Figure 3 As shown, limiting sleeves 6 are fixedly connected to the left and right sides of the placement cavity 4. A helical spring 7 is fixedly sleeved on the outer side of the limiting sleeve 6. A limiting groove 8 is opened on the side of the limiting slider 404 away from the pressing block 405. The limiting sleeve 6 and the limiting groove 8 are movably sleeved to provide precise guidance for the limiting slider 404, prevent it from shifting horizontally, ensure that the pressing block 405 is accurately embedded in the pressing groove 407 of the stamping template 5, and ensure the stable operation of the fixing component. One end of the helical spring 7 is connected to the limiting slider 404, and the other end is fixed to the side of the placement cavity 4. When the limiting slider 404 drives the pressing block 405 to clamp the stamping template 5, it stores energy and releases elastic force during the stamping process to assist clamping, resist vibration and impact, and prevent the template from loosening. This utility model, through the coordinated action of the limiting sleeve 6, the helical spring 7, and the limiting groove 8, enhances the positioning effect of the limiting slider 404 and reduces component wear through mechanical limiting and elastic assistance. It also significantly improves the stability and reliability of the stamping template 5, effectively reducing the product defect rate and improving production efficiency and processing quality.

[0027] Specifically, such as Figure 2 and Figure 3As shown, the bidirectional lead screw 403 passes through the interior of the two limiting slide grooves 402 and is threadedly connected to the two limiting sliders 404. The right end of the bidirectional lead screw 403 extends to the right side of the stabilizing platform 1 and is fixedly connected to a knob 9. The bidirectional lead screw 403 passes through the limiting slide grooves 402 and is threadedly connected to the limiting sliders 404. By rotating the bidirectional lead screw 403, the two limiting sliders 404 are driven to move synchronously in opposite directions or in opposite directions using the threaded transmission principle, thereby controlling the clamping and loosening of the pressing block 405 on the stamping template 5. Compared with other transmission methods, threaded transmission has the advantages of smooth transmission and high precision. The knob 9 is fixedly connected to the right end of the bidirectional lead screw 403, making it convenient for operators to manually rotate the bidirectional lead screw 403. The operation is simple and labor-saving, facilitating quick replacement of the stamping template 5 and improving work efficiency.

[0028] The bottom of the limiting slider 404 is adapted to the shape of the limiting groove 402, the positioning block 406 is adapted to the shape of the positioning groove 401, and the pressing groove 407 is adapted to the shape of the pressing block 405. The bottom of the limiting slider 404 is adapted to the shape of the limiting groove 402, ensuring that the limiting slider 404 can slide smoothly within the limiting groove 402, while limiting its displacement perpendicular to the sliding direction, ensuring the accuracy of the movement; the positioning block 406 is adapted to the shape of the positioning groove 401, enabling the stamping template 5 to be accurately positioned within the placement cavity 4, so that the stamping template 5 can accurately reach the predetermined position during installation, ensuring the accuracy of the stamping operation; the pressing groove 407 is adapted to the shape of the pressing block 405, so that the pressing block 405 can be tightly embedded in the pressing groove 407, providing reliable clamping force and preventing the stamping template 5 from shifting during the stamping process.

[0029] Specifically, such as Figure 3 As shown, the limiting sleeve 6 is movably sleeved inside the limiting groove 8. One end of the helical spring 7 is fixedly connected to the limiting slider 404, and the other end of the helical spring 7 away from the limiting slider 404 is fixedly connected to the side of the placement cavity 4. The movable sleeve 6 within the limiting groove 8 further enhances the limiting and guiding function of the limiting slider 404, ensuring that the limiting slider 404 will not deviate during movement. One end of the helical spring 7 is fixedly connected to the limiting slider 404, and the other end is fixed to the side of the placement cavity 4. When the limiting slider 404 moves towards clamping the stamping template 5, the helical spring 7 is compressed, storing elastic potential energy. When the stamping template 5 is installed in place, the helical spring 7 releases its elastic potential energy, assisting the pressing block 405 in maintaining the clamping state of the stamping template 5, preventing the stamping template 5 from loosening due to stamping vibration or external force interference. This structural design utilizes the elastic characteristics of the spring to enhance the clamping effect of the stamping template 5, improve the stability and reliability of the device operation, and ensure the smooth progress of the stamping operation.

[0030] Working principle and usage process of this utility model:

[0031] When the stamping template 5 needs to be installed, the operator turns the knob 9 to rotate the double-acting screw 403. Since the double-acting screw 403 is threadedly connected to the limiting slider 404 and the limiting slider 404 slides under the guidance of the limiting groove 402, the two limiting sliders 404 will move in opposite directions, causing the pressing blocks 405 to move away from each other. At this time, the positioning block 406 at the bottom of the stamping template 5 is aligned with the positioning groove 401 at the bottom of the placement cavity 4 and placed in to complete the initial positioning. Then, the knob 9 is turned in the opposite direction, and the double-acting screw 403 drives the limiting slider 404 to move the pressing blocks 405 towards each other until the pressing blocks 405 are embedded in the pressing groove 407 on the side of the stamping template 5, thereby firmly clamping the stamping template 5.
