[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A sleeve cold drawing forming die adjustment mechanism includes a base 1, a die adjustment component 4 is provided on the top of the base 1, a die fixing component 5 is provided on the top of the die adjustment component 4, and a cold drawing forming die body 2 is provided on the top of the die fixing component 5.

[0027] The mold adjustment assembly 4 includes a mounting base 401 fixedly connected to the top of the base 1. An auxiliary support rod 402 is fixedly connected to the top of the mounting base 401. A fixed frame 403 is slidably connected to the outside of the auxiliary support rod 402. An adjustment support plate 404 is fixedly connected to the top of the fixed frame 403. Lifting hydraulic cylinders 405 are fixedly connected to both sides of the bottom of the adjustment support plate 404. A groove 406 is opened inside the adjustment support plate 404. A screw adjuster 407 is fixedly connected inside the groove 406.

[0028] In this embodiment: by activating the lifting hydraulic cylinder 405, the piston rod of the lifting hydraulic cylinder 405 extends or retracts, pushing the adjusting support plate 404 to rise or fall. Since the adjusting support plate 404 is fixedly connected to the fixed frame 403, the fixed frame 403 will slide up and down synchronously along the auxiliary support rod 402. The raising and lowering of the adjusting support plate 404 drives the mold fixing assembly 5 and the cold drawing forming mold body 2 located above it to move precisely in the vertical direction, thereby meeting the mold height requirements of different sleeve cold drawing processes. When it is necessary to adjust the horizontal position of the mold... Adjustment: Start the lead screw adjusting machine 407. The lead screw adjusting machine 407 consists of a motor and a lead screw. The motor drives the lead screw to rotate, which in turn drives the movable support 501 to move on the adjusting support plate 404. Driven by the lead screw adjusting machine 407, the movable support 501, along with the mold fixing component 5 and the mold body, achieves precise horizontal positioning. This ensures that the mold is precisely aligned with the sleeve feeding device and the drawing equipment in the horizontal position, avoiding uneven stress on the sleeve during the cold drawing process due to the horizontal position deviation of the mold, and ensuring the dimensional accuracy and surface quality of the sleeve.

[0029] Specifically, such as Figure 4 As shown, the mold fixing assembly 5 includes a movable support 501 threadedly connected to the output end of the lead screw adjuster 407. A drive motor 502 is fixedly connected to the outside of the movable support 501. A dual-axis lead screw 503 is fixedly connected to the output end of the drive motor 502. Connecting seats 504 are threadedly connected to both sides of the dual-axis lead screw 503.

[0030] Specifically, such as Figure 4 As shown, a limiting support rod 505 is fixedly connected inside the movable support 501. The limiting support rod 505 is slidably connected to the connecting seat 504. A fixing plate 506 is fixedly connected to the top of the connecting seat 504.

[0031] Specifically, such as Figure 4 As shown, a limiting groove 507 is provided on the top of the movable support 501, and the limiting groove 507 is slidably connected to the fixed plate 506.

[0032] In this embodiment: When installing the cold-drawing forming mold body 2, the cold-drawing forming mold body 2 is placed between two fixed plates 506. The drive motor 502 is started, and the output shaft of the drive motor 502 drives the dual-axis lead screw 503 to rotate. Because the threads on both sides of the dual-axis lead screw 503 rotate in opposite directions, the connecting seats 504 connected by the threads on both sides will move relative to or away from each other along the limiting support rod 505 when the dual-axis lead screw 503 rotates. During the movement, the connecting seats 504 drive the fixed plate 506 fixed at the top to move synchronously. As the fixed plate 506 gradually approaches the mold, when the rubber protective pad 3 on the inner side of the fixed plate 506 contacts the outer wall of the mold, the drive motor 502 continues to move, utilizing the rubber protective pad 3... The elasticity allows it to fit tightly against the mold, thus fixing the mold. During the movement of the connecting seat 504, the sliding connection between the limiting support rod 505 and the connecting seat 504 plays a guiding role, ensuring that the connecting seat 504 can only move along the direction of the limiting support rod 505, preventing the connecting seat 504 from deviating during movement. At the same time, the limiting groove 507 opened at the top of the movable support 501 is slidably connected to the fixing plate 506, further restricting the movement trajectory of the fixing plate 506, so that the fixing plate 506 can only move horizontally within the range limited by the limiting groove 507, ensuring the stability and accuracy of the mold fixing process, preventing the mold from shaking or tilting during the fixing process, and ensuring the mold installation accuracy.

[0033] Specifically, such as Figure 5 As shown, a positioning groove 6 is provided on the inner side of the auxiliary support rod 402, and a positioning rod 7 is slidably connected to the outer side of the fixed frame 403. The positioning rod 7 is engaged with the positioning groove 6.

[0034] Specifically, such as Figure 5 As shown, the top of the adjusting support plate 404 is fixedly connected to the limiting slide rail 8, the top of the limiting slide rail 8 is slidably connected to the limiting slider 9, and the limiting slider 9 is fixedly connected to the movable support 501.

[0035] In this embodiment: By setting the positioning rod 7 and the positioning groove 6, when installing the mold adjustment assembly 4, the positioning rod 7 on the outside of the fixed frame 403 is aligned with the positioning groove 6 on the inside of the auxiliary support rod 402, and then the positioning rod 7 is pushed. When the positioning rod 7 is engaged in the positioning groove 6, the position of the fixed frame 403 is initially fixed. In subsequent use, if it is necessary to adjust the overall position or angle of the mold adjustment assembly 4, the engagement between the positioning rod 7 and the positioning groove 6 is released, the fixed frame 403 is moved to a suitable position, and then the positioning rod 7 is engaged in the positioning groove 6 again for fixation. When adjusting the mold height, the adjustment error caused by the shaking or displacement of the fixed frame 403 can be effectively avoided, ensuring the adjustment accuracy of the cold drawing forming mold body 2, thereby improving... The quality and consistency of cold-drawn sleeve forming are ensured by setting a limiting slide rail 8 and a limiting slider 9. When the horizontal position of the mold needs to be adjusted, the screw adjuster 407 is activated. The screw adjuster 407 drives the movable support 501 to move. During the movement of the movable support 501, the limiting slider 9 slides synchronously on the limiting slide rail 8, providing guidance for the movement of the movable support 501. The cooperation between the limiting slide rail 8 and the limiting slider 9 precisely limits the movement direction of the movable support 501. When the screw adjuster 407 drives the movable support 501 to adjust its horizontal position, it can effectively prevent the movable support 501 from shifting or shaking, ensuring the adjustment accuracy of the mold in the horizontal direction, thereby improving the dimensional accuracy and surface quality of the sleeve and reducing the defect rate.

[0036] Specifically, such as Figure 2 As shown, a protective pad 3 is bonded to the inner side of the fixing plate 506. The protective pad 3 is made of rubber.

[0037] Specifically, such as Figure 2 As shown, laser displacement sensors 10 are provided at both the top and bottom of the movable support 501, and a data processor 11 is electrically connected to the outside of the laser displacement sensor 10.

[0038] In this embodiment: By setting a protective pad 3, when installing the cold-drawing forming mold body 2, the mold is placed between the two fixing plates 506 of the mold fixing assembly 5. The drive motor 502 is started, and the drive motor 502 drives the dual-axis lead screw 503 to rotate, causing the connecting seat 504 to move the fixing plate 506 towards the mold. When the rubber protective pad 3 on the inner side of the fixing plate 506 contacts the outer wall of the mold, the drive motor 502 continues to drive. Utilizing the elasticity of the rubber protective pad 3, the protective pad 3 is tightly fitted to the mold, completing the mold fixing. The rubber protective pad 3 has good elasticity and wear resistance. When fixing the mold, the protective pad 3 can fill the tiny gap between the fixing plate 506 and the mold, increasing friction and making the mold more firmly fixed, effectively preventing the mold from shifting during the cold drawing process. At the same time, the protective pad 3 can prevent the fixing plate 506 from directly contacting the mold, preventing the fixing plate 506 from scratching or wearing the mold surface, protecting the mold's precision and... To improve surface quality, a laser displacement sensor 10 and a data processor 11 are used. After the mold is installed and before the cold drawing process begins, the laser displacement sensor 10 is activated. The laser displacement sensor 10 emits a laser beam to measure the distance between the movable support 501 and the mold, and transmits the collected data to the data processor 11 in real time. The data processor 11 analyzes and processes this data, compares it with preset standard data, and determines whether the mold position is accurate. If the data shows a deviation in the mold position, the operator adjusts the mold position further by adjusting components such as the lead screw adjuster 407, drive motor 502, or lifting hydraulic cylinder 405, based on the analysis results of the data processor 11. The laser displacement sensor 10 and the data processor 11 enable real-time monitoring and accurate analysis of the mold position, avoiding sleeve quality problems caused by inaccurate mold position and improving the reliability and stability of the production process.

[0039] Working principle: When using the cold drawing forming die adjustment mechanism, first place the cold drawing forming die body 2 on the die fixing assembly 5. Before use, the movable support 501 can be adjusted to a suitable initial position by the lead screw adjuster 407. The lead screw adjuster 407 consists of a motor and a lead screw. The motor drives the lead screw to rotate, and the lead screw drives the movable support 501 to move, which facilitates the subsequent precise installation of the die. Then, start the drive motor 502. The output end of the drive motor 502 drives the dual-axis lead screw 503 to rotate. The threads on both sides of the dual-axis lead screw 503 rotate in opposite directions, so that the threads on both sides rotate in opposite directions. When the dual-axis lead screw 503 rotates, the connecting seat 504 moves relative to or away from the limiting support rod 505. The movement of the connecting seat 504 drives the fixed plate 506 to move until the rubber protective pad 3 on the inner side of the fixed plate 506 is tightly attached to the outer wall of the mold. Utilizing the elasticity of the rubber protective pad 3, the mold can be firmly fixed while preventing the fixed plate 506 from directly contacting the mold and causing damage. After the mold is installed, when it is necessary to adjust the mold height, the lifting hydraulic cylinder 405 is activated. When the lifting hydraulic cylinder 405 is working, it pushes the adjusting support plate 404 to rise or fall. Because the adjusting support plate 404 and the fixed frame 403... Connected, the fixed frame 403 slides up and down along the auxiliary support rod 402 to ensure the stability and accuracy of the sliding process of the fixed frame 403, thereby driving the entire mold fixing assembly 5 and the mold body to accurately rise and fall in the vertical direction, meeting the mold height requirements of different sleeve cold drawing processes. When it is necessary to make a fine adjustment to the horizontal position of the mold, the screw adjuster 407 is started. The output end of the screw adjuster 407 drives the movable support 501 to move on the adjusting support plate 404. The limit slide rail 8 and the limit slider 9 cooperate with each other to limit the movement direction of the movable support 501, so that it can only move along the set direction. The mold slides smoothly in the horizontal direction, achieving precise positioning in the horizontal direction. This ensures that the mold is accurately aligned with the sleeve feeding device and the drawing equipment in the horizontal position. Before the cold drawing forming operation, the laser displacement sensors 10 at the top and bottom of the movable support 501 are used to detect the distance information of the mold. The laser displacement sensors 10 transmit the collected data to the data processor 11. The data processor 11 analyzes and processes the data to determine whether the position of the mold is accurate. If the data shows that there is a deviation in the position of the mold, the operator can further adjust the mold according to the processing results to ensure the accuracy of the cold drawing operation.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
