Description

Technical Field

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

[0002] In fields such as machinery manufacturing, automotive parts, and electronic components, stamping has become one of the core processes for metal sheet processing due to its high efficiency and stable forming accuracy. However, stamping dies, as key components of stamping presses for forming specific workpieces, need to be frequently changed according to the shape and size requirements of different products—for example, when the same production line needs to alternately produce various specifications of gaskets and brackets, the number of die changes per day is high. The current mainstream fixed structure of stamping dies mainly suffers from the following problems that contradict the requirement of "quick assembly and disassembly": Most existing stamping dies are directly locked to the worktable by multiple sets of high-strength bolts. During disassembly and assembly, tools such as wrenches and torque guns are needed to loosen / tighten the bolts one by one. This process consumes a lot of manpower and time, resulting in low efficiency in changing stamping dies. Therefore, it is necessary to redesign and modify the stamping die fixing structure of the stamping machine to effectively prevent the stamping die from being difficult to disassemble and assemble. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a stamping die fixing structure for a stamping machine, which has the advantages of easy disassembly and assembly and strong fixing stability.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stamping die fixing structure for a stamping machine, comprising a stamping machine worktable, with limit blocks fixedly connected to all four sides of the top of the stamping machine worktable, an adjusting box provided on the top of the stamping machine worktable, the adjusting box fitting against the limit blocks, a stamping die body fixedly connected to the top of the adjusting box, fixing blocks fixedly connected to both sides of the top of the stamping machine worktable, and slots provided on adjacent sides of the left and right fixing blocks, and sliding grooves provided on both sides of the bottom of the inner wall of the adjusting box, with movable plates slidably connected left and right inside the sliding grooves, and the two movable plates being far apart from each other. A plug rod is fixedly connected to one side of the movable plate. The end of the plug rod away from the movable plate extends to the outside of the adjustment box and is inserted into the slot. Compression springs are fixedly connected to both sides of the inner wall of the adjustment box. The end of the compression spring away from the adjustment box is fixedly connected to the movable plate. An adjustment frame is fixedly connected to the adjacent side of the two movable plates. A first threaded rod is rotatably connected inside the adjustment box. A movable groove is provided at the top of the inner wall of the adjustment box. A slider is slidably connected back and forth inside the movable groove. A drive frame is threadedly connected to the surface of the first threaded rod. The drive frame works in conjunction with the adjustment frame. The bottom of the slider is fixedly connected to the top of the drive frame.

[0005] As a preferred embodiment of this utility model, the regulating box is internally fixedly connected to a bearing, with the outer ring of the bearing fixedly connected to the regulating box and the inner ring of the bearing fixedly connected to the first threaded rod.

[0006] In a preferred embodiment of this invention, a sleeve is fixedly connected to the front of the regulating box, the sleeve is rotatably connected to the first threaded rod, and a second threaded rod is threadedly connected to the inside of the sleeve. The second threaded rod is in close contact with the first threaded rod, and a rotating handle is fixedly connected to the front of the first threaded rod and the surface of the second threaded rod.

[0007] As a preferred embodiment of this utility model, support columns are fixedly connected to the four corners of the top of the stamping machine workbench, the top of the support columns is attached to the bottom of the stamping die body, and the top of the fixing block is attached to the bottom of the stamping die body.

[0009] As a preferred embodiment of this invention, the sides of the adjustment frame and the drive frame that are in contact with each other are both smooth.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a limiting block to initially position the adjusting box, and then uses the insertion of the movable plate, the insert rod, and the slot on the fixed block to achieve fixation. The movable plate can then be easily moved via the cooperation of the first threaded rod, the drive frame, and the adjusting frame, enabling rapid assembly and disassembly of the stamping die body. The entire structure ensures the accurate positioning of the stamping die body after installation and enhances the stability of the fixation through multiple coordinations. It effectively solves the problems of cumbersome assembly and disassembly and insufficient stability of traditional fixing methods, making it suitable for scenarios requiring frequent die replacement and improving operational efficiency.

[0014] 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.

[0015] like Figures 1 to 4As shown, a stamping die fixing structure for a stamping machine includes a stamping machine worktable 1. Limiting blocks 2 are fixedly connected to all four sides of the top of the stamping machine worktable 1. An adjusting box 3 is provided on the top of the stamping machine worktable 1, and the adjusting box 3 fits against the limiting blocks 2. A stamping die body 4 is fixedly connected to the top of the adjusting box 3. Fixing blocks 5 are fixedly connected to both sides of the top of the stamping machine worktable 1, and slots 6 are provided on the adjacent side of the left and right fixing blocks 5. Sliding grooves are provided on both sides of the bottom of the inner wall of the adjusting box 3, and movable plates 7 are slidably connected to the inside of the sliding grooves. Furthermore, each of the two movable plates 7, on the side furthest from each other, is fixedly connected to a plug rod 8. The end of the plug rod 8 furthest from the movable plate 7 extends to the outside of the adjusting box 3 and is inserted into the slot 6. Both sides of the inner wall of the adjusting box 3 are fixedly connected to a compression spring 9. The end of the compression spring 9 furthest from the adjusting box 3 is fixedly connected to the movable plate 7. An adjusting frame 10 is fixedly connected to the adjacent side of each of the two movable plates 7. A first threaded rod 11 is rotatably connected inside the adjusting box 3. A movable groove is provided at the top of the inner wall of the adjusting box 3, and a slider is slidably connected back and forth inside the movable groove. The threaded rod 11 has a threaded connection to a drive frame 12, which works in conjunction with an adjusting frame 10. The drive frame 12 and the adjusting frame 10 are in a close-fitting relationship. For example, when the drive frame 12 moves to the back, it pushes the adjusting frames 10 on both sides away from each other. The bottom of the slider is fixedly connected to the top of the drive frame 12. The cooperation between the movable groove and the slider limits the drive frame 12, so that the drive frame 12 can only move back and forth along the movable groove. Thus, when the first threaded rod 11 rotates, the drive frame 12 can move forward or backward. All standard parts used in this utility model can be purchased from the market. Special-shaped parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification are prior art known to those skilled in the art, and this application will not describe them in detail.

[0016] refer to Figure 3 The regulating box 3 is internally fixedly connected to a bearing, and the outer ring of the bearing is fixedly connected to the regulating box 3, while the inner ring of the bearing is fixedly connected to the first threaded rod 11.

[0017] As a technical optimization of this utility model, the bearing arrangement inside the adjusting box 3 effectively reduces the friction between the first threaded rod 11 and the adjusting box 3 during rotation, making the rotation of the first threaded rod 11 smoother and more stable. This avoids increased wear caused by direct contact and extends the service life of both the first threaded rod 11 and the adjusting box 3. Simultaneously, the bearing provides stable support for the first threaded rod 11, preventing it from shifting or wobbling during rotation. This ensures the accuracy of the drive frame 12 in moving the adjusting frame 10, thereby guaranteeing the stability of the engagement between the insertion rod 8 and the slot 6 and improving the operational reliability of the entire fixed structure.

[0018] refer to Figure 4 A sleeve 13 is fixedly connected to the front of the regulating box 3. The sleeve 13 is rotatably connected to the first threaded rod 11. A second threaded rod 14 is threadedly connected inside the sleeve 13. The second threaded rod 14 is in close contact with the first threaded rod 11. A rotating handle is fixedly connected to the front of the first threaded rod 11 and the surface of the second threaded rod 14.

[0019] As a technical optimization of this utility model, the sleeve 13 on the front of the adjusting box 3 cooperates with the second threaded rod 14. After the first threaded rod 11 is adjusted to the correct position, the second threaded rod 14 can be used to tighten and lock it, preventing the first threaded rod 11 from loosening due to vibration during the operation of the stamping machine. This ensures that the insertion rod 8 and the slot 6 always maintain a stable insertion state, improving the vibration resistance of the fixing structure. The rotating handle makes it convenient for operators to rotate the first threaded rod 11 and the second threaded rod 14, reducing the difficulty of adjustment and making disassembly and assembly operations more convenient and labor-saving. It balances the stability of the fixing and the convenience of operation, making it suitable for operators of different skill levels.

[0020] refer to Figure 1 Support columns 15 are fixedly connected to the four corners of the top of the stamping machine worktable 1. The top of the support column 15 is attached to the bottom of the stamping die body 4, and the top of the fixing block 5 is attached to the bottom of the stamping die body 4.

[0021] As a technical optimization of this utility model, the support column 15 and the fixing block 5 on the top of the stamping machine worktable 1 jointly support the stamping die body 4, which can distribute the stamping force borne by the stamping die body 4 to multiple support points, avoiding deformation or damage to the stamping die body 4 due to excessive force at a single point, and extending the service life of the stamping die body 4. At the same time, the close fit between the support column 15 and the fixing block 5 and the bottom of the stamping die body 4 further enhances the stability of the stamping die body 4 after installation, reduces shaking during operation, ensures the accuracy of stamping processing, and improves the load-bearing capacity of the overall structure.

[0022] refer to Figure 3 The surface of the compression spring 9 is provided with an anti-rust coating.

[0023] As a technical optimization of this utility model, the anti-rust coating on the surface of the compression spring 9 effectively isolates it from corrosive media such as air and moisture, preventing corrosion during long-term use and ensuring that the compression spring 9 maintains good elasticity. This allows the compression spring 9 to continuously provide a stable thrust to the movable plate 7, ensuring a tight connection between the insertion rod 8 and the slot 6, and preventing loosening due to corrosion failure of the compression spring 9. Simultaneously, it reduces the frequency of replacement due to compression spring 9 damage, lowers maintenance costs, and improves the long-term stability and durability of the fixing structure.

[0024] refer to Figure 3 Both sides of the adjustment frame 10 and the drive frame 12 that are in contact with each other are smooth.

[0025] As a technical optimization of this utility model, by making the side where the adjusting frame 10 and the drive frame 12 fit together smooth, the frictional resistance between the two during relative movement can be significantly reduced, making the movement of the adjusting frame 10 by the drive frame 12 smoother and less strenuous, and reducing the phenomenon of jamming during the adjustment process. At the same time, the smooth surface can reduce the degree of wear between the two, extend the service life of the adjusting frame 10 and the drive frame 12, and ensure that good fit accuracy is maintained even after long-term use. This design improves the convenience and efficiency of the adjustment operation, ensures the accuracy of the extension and retraction adjustment of the insertion rod 8, and further enhances the practicality of the fixing structure.

[0026] The working principle and usage process of this utility model are as follows: When the operator needs to disassemble the stamping die body 4, the operator rotates the second threaded rod 14 to separate the second threaded rod 14 from the first threaded rod 11, thereby releasing the lock on the first threaded rod 11. Then, the first threaded rod 11 is rotated, and the adjustment drive frame 12 moves forward. Under the action of the compression spring 9, the compression spring 9 pushes the two movable plates 7 on the left and right sides closer to each other, ensuring that the adjustment frame 10 is always in contact with the drive frame 12, so that the insertion rods 8 on the left and right sides are close to each other until the insertion rods 8 exit the slot 6, thereby releasing the fixation on the adjustment box 3. Then, the operator moves the adjustment box 3 upward and removes the stamping die body 4. The installation process is the same. The limiting block 2 can help the operator place the adjustment box 3 in the preset position. The tops of the support column 15 and the fixing block 5 are in contact with the bottom of the stamping die body 4, which can play a role in supporting the stamping die body 4 during stamping.
