Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a stamping die for automotive stamping parts. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] A search revealed a patent with publication number CN220574514U, which proposes a stamping die for automotive stamping parts production. The die comprises a worktable, a fixed plate, a fixing mechanism, a die body, a limiting block, a locking block, a connecting block assembly, a nozzle, a cleaning box, and a water pump assembly. During use, the fixed plate is fixed to the worktable, the slider is fixed to the fixed plate, and the mounting plate is fixed to the die body. When the die body is changing molds, the limiting block releases the restriction, allowing the die body to slide on the surface of the slider via the mounting plate, thus releasing the mounting plate from contact with the slider and facilitating mold changing operations.

[0004] The limiting block in this solution uses a knob or threaded hole to fix and detach. However, in the automotive stamping production scenario, in order to ensure the machining accuracy of the mold and the surface quality of the parts, cleaning fluid needs to be continuously sprayed through a nozzle during the stamping process to clean the metal debris on the mold surface. This cleaning fluid and metal debris can easily seep into the threaded hole through the gap between the limiting block and the mounting plate and the knob during mold changing operations and daily use, forming a buildup. This will corrode the inner wall of the threaded hole and the thread structure of the knob. Long-term use can easily lead to thread corrosion and jamming, affecting the smoothness of fixing and detaching the limiting block. The metal debris will fill the thread gap. When the knob is rotated, the debris will aggravate the wear of the thread surface, causing a decrease in thread accuracy. In severe cases, it may even cause the thread to strip, making it impossible for the limiting block to be effectively fixed. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Example

[0022] Please refer to the following: Figures 1 to 6 This embodiment provides a stamping die for automotive stamping parts, applied to cold stamping processes of automotive stamping parts. It solves the problem of existing die limiting structures being susceptible to corrosion from cleaning fluids and metal debris, leading to thread corrosion, jamming, and wear. Through a threadless locking structure and a plugging hole design, it achieves stable locking of the processing die base and convenient die replacement, while preventing impurities from entering and extending the equipment's service life. The die includes a base 1, a mounting plate 2, a slide rail 3, a connecting frame plate 4, and a processing die base 5. The base 1 provides basic support, the mounting plate 2 and the slide rail 3 form a sliding guide base, and the connecting frame plate 4 supports the processing die base 5 and enables position adjustment. The locking and plugging components work together to ensure locking reliability and structural protection.

[0023] Specifically, the base 1 is a horizontally positioned support carrier, and the mounting plate 2 is fixedly connected to the top surface of the base 1. A pair of slide rails 3 are symmetrically fixed on the top surface of the mounting plate 2. The slide rails 3 extend horizontally to provide precise guidance for the movement of the connecting frame plate 4. The connecting frame plate 4 is slidably mounted on the pair of slide rails 3 and can move smoothly along the length of the slide rails 3. A processing mold base 5 is fixedly mounted on its top surface. The processing mold base 5 is used to install the cavity of the stamping die to realize the plastic deformation or separation processing of automotive stamping parts.

[0024] The connecting frame plate 4 includes two slide blocks 8 that are slidably mounted on two slide rails 3 respectively. The two slide blocks 8 are fixedly connected by a connecting plate to form a whole, ensuring synchronous movement during movement and preventing the processing mold base 5 from tilting. Locking blocks 9 are fixedly provided at both ends of the slide blocks 8. The locking blocks 9 extend vertically and are used to cooperate with the slide rails 3 to lock the position of the connecting frame plate 4.

[0025] The slide rail 3 has several evenly spaced insertion holes 6 at both ends along its own axis. The number of insertion holes 6 is adapted to the adjustment position of the processing mold base 5. A movable rod 14 is inserted and slidably installed vertically inside the locking block 9. An insertion block 15 is fixedly installed at the bottom end of the movable rod 14. The shape of the insertion block 15 is precisely adapted to the inner wall of the insertion hole 6 and can be inserted into the insertion hole 6 to form a lock. A second spring 16 is sleeved on the outside of the movable rod 14. The second spring 16 is located inside the locking block 9, and its two ends abut against the inner wall of the locking block 9 and the outer wall of the movable rod 14, respectively, providing a downward elastic thrust for the movable rod 14. In the initial state, the elastic force of the second spring 16 is greater than the elastic force of the first spring 13 of the subsequent sealing component 7, pushing the movable rod 14 and the insertion block 15 to move downward. The insertion block 15 is inserted into the corresponding insertion hole 6. Through the cooperation of multiple insertion blocks 15 and insertion holes 6, a stable lock is formed on the slide rail 3 for the connecting frame plate 4.

[0026] Each of the insertion holes 6 of the slide rail 3 is provided with a sealing component 7. The sealing component 7 includes a rod 12 that is slidably inserted into the slide rail 3 in the vertical direction. A baffle 11 is fixedly provided at the top of the rod 12. The baffle 11 is slidably installed inside the insertion hole 6. Its outer diameter is adapted to the inner diameter of the insertion hole 6, and it can completely block the opening of the insertion hole 6. A first spring 13 is sleeved on the outside of the rod 12. The first spring 13 is located inside the insertion hole 6. Its two ends abut against the bottom inner wall of the insertion hole 6 and the outer wall of the rod 12, respectively, to provide upward elastic support for the baffle 11. When the plug 15 is not inserted into the socket 6, the first spring 13 pushes the baffle 11 upward, so that the top surface of the baffle 11 is flush with the top surface of the slide rail 3, completely sealing the opening of the socket 6, preventing the cleaning fluid sprayed during the stamping process and the metal debris generated from entering the socket, thus preventing structural failures caused by impurities from the source; when the plug 15 is inserted into the socket 6, the plug 15 presses the baffle 11 downward, the first spring 13 contracts, and the baffle 11 moves downward to avoid it, without affecting the stable cooperation between the plug 15 and the socket 6, and the locking and sealing functions do not interfere with each other.

[0027] A connecting block 17 is fixedly installed on the top of each of the movable rods 14. The top of multiple connecting blocks 17 is fixedly connected to the same synchronization plate 10, which extends horizontally and covers the top of all the movable rods 14. When it is necessary to adjust the position of the machining mold base 5 or replace the connecting frame plate 4, lift the synchronous plate 10 upward. The synchronous plate 10 drives all the movable rods 14 to move upward synchronously through the connecting block 17. The movable rods 14 compress the second spring 16, and the insert block 15 disengages from the insertion hole 6, releasing the lock. At this time, push the connecting frame plate 4 along the slide rail 3 until the machining mold base 5 reaches the target position, and the corresponding insertion hole 6 is aligned with the insert block 15. Release the synchronous plate 10, the second spring 16 returns to its deformation, and pushes the movable rod 14 and the insert block 15 downward, re-inserting them into the insertion hole 6 to complete the locking. The whole process does not require rotation, avoiding the use of threaded structures and completely solving the problems of thread corrosion and jamming. If it is necessary to replace the machining mold base 5, the connecting frame plate 4 can be directly pushed away along the slide rail 3. After replacing the new connecting frame plate 4 and the machining mold base 5, the above locking steps can be repeated. The mold replacement operation is convenient and efficient.

[0028] A rotating block 18 is rotatably mounted on the outside of the movable rod 14. The rotating block 18 is located below the connecting block 17, and a pair of locking plates 20 are symmetrically fixed on both sides of it. A pair of locking plates 21 corresponding to the positions of the locking plates 20 are fixedly mounted on the top surface of the locking block 9. The locking plates 21 have locking holes 22 inside, and the shape of the locking holes 22 is adapted to the locking plates 20. When the insert 15 is inserted into the insertion hole 6 to complete the locking, the pair of levers 19 on the top of the rotating block 18 are moved to drive the rotating block 18 to rotate around the movable rod 14, so that the locking plates 20 are inserted into the locking holes 22 of the locking plates 21, forming a strong secondary locking of the movable rod 14. This prevents the movable rod 14 from moving upward due to accidental contact with the synchronous plate 10 during the stamping process, further improving the locking reliability. When unlocking is required, the levers 19 are moved in the opposite direction to disengage the locking plates 20 from the locking holes 22, and the synchronous plate 10 can be lifted normally. The operation is flexible and does not add any extra steps.

[0029] In actual automotive stamping parts processing scenarios, before stamping, the processing die base 5 is installed on the connecting frame plate 4, and the connecting frame plate 4 is pushed along the slide rail 3 to the processing position. The second spring 16 pushes the insert block 15 into the corresponding insertion hole 6, and the baffle 11 is pressed down. The rotating lever 19 makes the locking insert plate 20 insert into the locking hole 22, completing the double locking. During the stamping process, the nozzle continuously sprays cleaning fluid to clean the metal debris on the surface of the processing die base 5. The insertion hole 6 where the insert block 15 is not inserted is blocked by the baffle 11 under the action of the first spring 13, so that the cleaning fluid and debris cannot enter. After the stamping is completed, if the position of the processing die base needs to be adjusted, the lever 19 is reversed to unlock, the synchronous plate 10 is lifted to make the insert block 15 disengage from the insertion hole 6, the connecting frame plate 4 is pushed to the new position, and the synchronous plate 10 is released to relock. If the processing die base needs to be replaced, after unlocking, the connecting frame plate 4 is pushed away from the slide rail 3, and after replacement, it can be reinstalled and locked. There is no threaded structure involved in the whole process, avoiding failures caused by impurities.

[0030] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
