Description

Technical Field

[0002] Multi-station progressive die is a die design and processing technology that can complete multiple processes or parts processing in a single stamping process. It sets multiple working positions in the die, each equipped with different tools or punches, so that multiple steps can be performed simultaneously in each stamping cycle, and complex parts or components can be produced efficiently. The automatic twisting and stacking locking mechanism plays a key role in this process, ensuring that the tool is accurately positioned and locked in the correct position to improve production efficiency, ensure processing quality, and reduce production line downtime.

[0003] In most cases, during the use of the existing twisting and stacking locking mechanism, a single twisting and stacking locking ring is used, which is then driven by a pulley to rotate the twisting and stacking locking ring to work, thereby achieving the effect of lifting and clamping the workpiece. However, when the punch head descends during use, there will be a huge impact force. Using a single twisting and stacking locking ring to clamp the workpiece will cause the twisting and stacking locking ring to rotate, which will lead to unsatisfactory clamping effect. Therefore, an automatic twisting and stacking locking mechanism for a multi-station progressive die is proposed to solve the above problem. Utility Model Content

[0024] Specifically, when it is necessary to lock the workpiece, first start the motor 4 to drive the belt 5 to start rotating; the start of the motor 4 converts mechanical energy into kinetic energy, and through the transmission of the belt 5, drives the connected screw rod 3 to rotate synchronously; the rotation of the screw rod 3 drives the threaded sleeve 6 to rotate synchronously, and the threaded sleeve 6 is precisely designed and manufactured to ensure that it can form a close fit with the screw rod 3 during rotation, thereby achieving efficient force transmission; during the rotation of the threaded sleeve 6, the sleeve 9 is driven to rotate on the inner wall of the limiting groove 10; the design of the limiting groove 10 ensures that the movement path of the sleeve 9 is controlled and avoids any unnecessary deviation or misalignment; this design not only improves the stability of the sleeve 9, but also ensures the operating accuracy and reliability of the entire system; as the threaded sleeve 6 rotates, it gradually drives the clamping plate 13 to rise and lift the workpiece; the clamping plate 13 is designed to evenly distribute the applied pressure, so The workpiece is quickly and firmly locked in a predetermined position; this process not only improves work efficiency, but also ensures the stability of the workpiece during the locking process, avoiding possible loosening or falling off problems; at the same time, the limit component 11 further ensures the stability of the system through its telescopic adjustment function; the limit component 11 can adjust the length and position as needed, so as to accurately control the movement range of the threaded sleeve 6; this design not only enhances the flexibility of the system, but also improves the convenience of operation, so that the workpiece can obtain the best fixing effect under different conditions; the threaded sleeve 6 itself has the characteristic of not rotating along the screw rod 3, and this characteristic further enhances the stability of the system; even after long-term use, the threaded sleeve 6 can still maintain its stable position, and will not rotate or move due to friction or vibration; this design ensures that the workpiece remains stable during the locking process, avoiding any factors that may affect the work quality.

[0025] Reference Figure 1 and Figure 4 The lower surface of the mounting plate 1 is fixedly connected with a fixing box 14, and a through hole 15 is opened inside the mounting plate 1 and the fixing box 14; a plug rod 16 is slidably connected inside the fixing box 14 and the mounting plate 1, and the plug rod 16 is slidably connected to the inner wall of the through hole 15, and a mounting seat 25 is fixedly connected to the upper surface of the plug rod 16; a left-right symmetrical card block 19 is slidably connected inside the plug rod 16, and a spring 2 17 is fixedly connected between the two card blocks 19, and the outer wall of the card block 19 is slidably connected to the outer wall of the fixing box 14 A slide groove 18 is provided inside the fixed box 14, and a sliding plate 20 is slidably connected inside the fixed box 14; a limit plate 21 is fixedly connected to one side of the outer wall of the sliding plate 20, and the limit plate 21 is slidably connected to the inner wall of the slide groove 18, and a second clamping block 22 is fixedly connected to one side of the outer wall of the sliding plate 20, and the second clamping block 22 passes through the interior of the fixed box 14 and is slidably connected to the inner wall of the insertion rod 16; a telescopic rod 23 is fixedly connected to the other side of the outer wall of the sliding plate 20, and a spring 3 24 is sleeved on the outer wall of the telescopic rod 23;

[0026] Specifically, first, by installing the mounting seat 25 at the discharge port below the mold, the foundation is laid for the subsequent installation process; the positioning of the mounting seat 25 ensures the stability and accuracy of the entire system; then, the mounting plate 1 is inserted into the through hole 15, and the expansion and contraction force of the spring 2 17 is used to push the block 1 19 so that it is engaged with the outer wall of the fixed box 14, thereby achieving initial stability; this step ensures that the mounting plate 1 can be firmly fixed in the predetermined position to prevent any displacement; when the insertion rod 16 continues to push downward to the vicinity of the block 2 22, the expansion and contraction force of the spring 3 24 further exerts its effect, driving the sliding plate 20 to move forward; this movement causes the limit plate 21 to move in The slide groove 18 is limited and slides on the inner wall, thereby achieving a quick installation effect; this design makes the installation process more convenient and efficient, reduces the operation time, and improves production efficiency; when the installation mechanism needs to be disassembled, the spring 2 17 can be contracted by pressing the card block 19, thereby releasing the engagement state between the card block 19 and the fixed box 14; this design makes the disassembly process also simple and quick, and only needs to gently press the card block 19, and the mounting plate 1 can be quickly separated from the fixed box 14, thereby achieving the effect of further disassembling the installation mechanism; in this way, not only the installation and disassembly operation steps are simplified, but also the safety and reliability of the entire process are ensured.

[0027] Working principle: When in use, first install the mounting seat 25 at the discharge port below the mold, then insert the mounting plate 1 into the through hole 15, and push the clamping block 19 to engage with the outer wall of the fixing box 14 through the telescopic force of the spring 2 17 to achieve initial stability. At this time, when the insertion rod 16 reaches the vicinity of the clamping block 22, the sliding plate 20 is driven by the telescopic force of the spring 3 24 to push the limiting plate 21 to slide on the inner wall of the slide groove 18, thereby achieving the effect of rapid installation. When disassembling, the clamping block 19 is pressed to make the spring 2 17 contract, thereby achieving the effect of further disassembling the installation mechanism;

[0028] Secondly, at this time, the belt 5 is driven to rotate by starting the motor 4, and then the belt 5 drives the screw rod 3 to rotate. At this time, the screw rod 3 will drive the threaded sleeve 6 to rotate. Through the rotation of the threaded sleeve 6, it is convenient to drive the sleeve 9 to rotate within the inner wall of the limiting groove 10, so that the threaded sleeve 6 drives the clamping plate 13 to lift the workpiece, thereby achieving a quick locking effect. At the same time, through the telescopic adjustment of the limiting component 11 and the characteristic that the threaded sleeve 6 itself will not rotate along the screw rod 3, it is convenient to further stabilize the threaded sleeve 6 to stabilize the workpiece.
