Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die quick die changing mechanism and a system thereof, which are intended to shorten die changing time and improve production efficiency. Background Art

[0002] In stamping production, changing dies and materials is a key factor influencing production efficiency. Traditional die-changing mechanisms typically consist of a die clamp, die transfer arm, die lifter, pneumatic and hydraulic unit, and a die-changing trolley. These mechanisms are complex and cumbersome to operate. For lightweight parts like silencers, which are made of nitrile rubber, steel, cold adhesive, and release paper, the stamping dies are relatively light (70-90 kg), allowing operators to easily move the dies on the press workbench. Therefore, improvements to traditional die-changing mechanisms are necessary to accommodate the rapid changes required for these lightweight dies.

[0003] Based on the above problems existing in the prior art, designing a quick-change mechanism for convenient and rapid replacement of stamping dies has become a problem to be solved by this application. Utility Model Content

[0004] One of the purposes of the present invention is to provide a quick die-changing mechanism for a stamping die, which achieves a fast and convenient die-changing process by eliminating redundant components such as a die lifter and optimizing the design of a die-moving arm and a die-changing trolley.

[0005] In order to solve the above technical problems, the present application provides a stamping die rapid die changing mechanism, which is installed in conjunction with the punching machine workbench and includes a die shifting slide, a die changing trolley and a die changing track; the die changing trolley is installed on the die changing track and can slide laterally along the die changing track;

[0006] The die changing trolley is provided with a die station, and the die changing trolley can move along the die changing track to the punch press end;

[0007] The die-shifting slide is mounted between the punch press worktable and the die-changing trolley, so that the die-shifting slide, the punch press worktable and the upper surface of the die-changing trolley are in the same plane, thereby forming a continuous sliding surface in the same plane, which is used to translate the disassembled stamping die from the punch press worktable to the lower die station of the die-changing trolley, and push the stamping die to be replaced into the punch press worktable.

[0008] In addition to the above-mentioned technical solutions, this application also makes improvements in the following aspects:

[0009] In some embodiments, the mold changing track includes a base plate and a sliding track mounted on an upper portion of the base plate.

[0010] In some embodiments, the mold station of the mold changing trolley is set as a double station, namely an upper mold station and a lower mold station, which are used to place the stamping mold during the upper and lower mold processes.

[0011] In some embodiments, the mold changing trolley further includes a frame and a sliding assembly disposed at the bottom of the frame.

[0012] In some embodiments, the sliding assembly includes a high wheel and a low wheel, wherein the high wheel is mounted on the sliding track, and the low wheel is mounted on the bottom plate and in contact with the bottom plate.

[0013] In some embodiments, rolling elements are provided on the upper surfaces of the mold shifting slide and the mold station, and the rolling elements are provided in multiple groups and are evenly distributed on the upper surfaces of the mold shifting slide and the mold station.

[0014] In some embodiments, a dust shield is provided on the upper surface of the mold station, and holes are opened on the dust shield corresponding to the rolling elements provided on the mold station; the holes are exposed on the upper part of the rolling elements.

[0015] In some embodiments, a hanging rack is provided on one side of the frame of the mold changing trolley for placing the mold shifting slide.

[0016] In some embodiments, limit blocks are provided at both ends of the sliding track to prevent the mold transfer trolley from sliding out of the sliding track.

[0017] Another object of the present application is to provide a stamping die rapid die change system, including the stamping die rapid die change mechanism described above, and a punching machine and stamping die matched therewith.

[0018] Beneficial effects of the utility model:

[0019] 1. This application optimizes the design of the die transfer arm and die change trolley, and incorporates the use of a die transfer slide to enable the mold to be smoothly and quickly moved between the punch press worktable and the die change trolley during the die change process. This improvement significantly shortens die change time, reduces manual intervention during the die change process, and improves production efficiency.

[0020] 2. This application adopts a dual-station setup. While one station is removing the mold, the other station has a new mold ready and can be pushed directly into the punch press worktable. This parallel operation method significantly reduces the total mold change time, making the production process more compact and efficient.

[0021] 3. The mold-changing track in this application utilizes a high-low wheel design. The high wheels ensure smooth movement and guidance of the mold-changing trolley on the sliding track, preventing deviation from the path; the low wheels directly contact the ground, sharing the weight and enhancing adaptability. This design not only improves the stability of the mold-changing trolley, but also enables it to adapt to different ground environments, enhancing the reliability and durability of the entire mold-changing mechanism.

[0022] 4. The rolling element design on the mold transfer slide and the mold station's upper surface significantly reduces frictional resistance during mold movement, allowing operators to easily push the mold and remove and install it without exerting excessive force. This not only reduces operator labor intensity but also improves the safety and comfort of mold change operations.

[0023] 5. The dust shield and circular holes on the upper die station effectively prevent stamping waste from falling into the gaps between the rolling elements, preventing it from jamming and causing wear on the rolling elements. This not only protects the rolling elements from damage but also ensures smooth die transfer, minimizing interruptions or delays in die changes caused by waste interference.

[0030] I. Explanation of Descriptive Terms in This Application

[0031] The embodiments provided in conjunction with the technical solutions of this application are intended to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0033] In this application, when a specific device is described as being located between a first device and a second device, an intervening device may or may not be present between the specific device and the first device or the second device. When a specific device is described as being connected to another device, the specific device may be directly connected to the other device without an intervening device, or may be not directly connected to the other device but with an intervening device.

[0034] In addition, this application does not discuss in detail the technologies and equipment known to ordinary technicians in the relevant fields, but where appropriate, the technologies and equipment should be considered part of the specification.

[0035] The application scenario of this application is mainly based on the die changing mechanism of lightweight stamping dies, and can also be applied to other scenarios according to its functions. Its application scenario is not restricted or limited by the specific embodiments recorded in this application.

[0036] 2. The traditional mold changing mechanism is usually composed of a mold clamp, a mold moving arm, a mold lifter, a pneumatic hydraulic unit and a mold changing trolley. The structure is complex and the replacement operation is cumbersome. It is not suitable for the problem of rapid replacement of lightweight molds (such as silencer molds). This application specifically provides a technical solution to the above problem. The technical solution, working principle and technical effect of this application are described in detail below in combination with specific embodiments.

[0037] like Figure 1 、 2 As shown, this application records a quick die changing mechanism for a stamping die, which is specifically used for the quick replacement of a silencer die. It is installed in conjunction with a punching machine workbench 8 to achieve quick replacement of a silencer die 9.

[0038] The stamping die quick die changing mechanism cooperates with the punching machine workbench 8 when in use and is installed on one side of the punching machine 1. The mechanism specifically includes a die shifting slide 2, a die changing trolley 3 and a die changing track 4.

[0039] To enable rapid die changes, the die-shifting slide 2 is mounted between the punch press table 8 and the die-changing trolley 3, so that the upper surfaces of the die-shifting slide 2, the punch press table 8, and the die-changing trolley 3 are in the same plane, thereby forming a continuous sliding surface. The continuous sliding surface formed by the die-shifting slide 2, the punch press table 8, and the upper surfaces of the die-changing trolley 3 eliminates obstacles during the die removal and installation process, improving operational convenience and production efficiency.

[0040] During operation, the die changing trolley 3 is installed on the die changing track. The die changing trolley 3 can move along the die changing track 4 to the end of the punch press 1, and is tightly docked with the punch press workbench 8 through the die moving slide 2. It is used to translate the disassembled stamping die 9 from the punch press workbench 8 to the lower die station 312 of the die changing trolley 3, and push the die to be replaced at the upper die station 311 into the punch press workbench 8.

[0041] In order to facilitate the placement of the stamping die 9 during the die changing process, a die station 31 is provided on the die changing trolley 3 for carrying and fixing the stamping die 9 to be replaced or disassembled.

[0042] When the mold needs to be replaced, the disassembled mold can be transferred from the punch press worktable 8 to the lower mold station 312 of the mold changing trolley 3 through the mold moving slide 2, and the stamping mold 9 to be replaced is pushed along the upper mold station 311 and the mold moving slide 2 to the punch press worktable 8 for installation.

[0043] The mold changing track 4 in this application includes a base plate 41 and a sliding track 42 mounted on the upper portion of the base plate 41, providing a stable sliding path for the mold changing trolley 3 to ensure accurate alignment during the mold changing process. In this embodiment, the sliding track 42 is a circular steel pipe structure.

[0044] In order to improve the efficiency of mold changing, the mold station 31 of the mold changing trolley 3 is set as a double station, namely the upper mold station 311 and the lower mold station 312, which are used to place the stamping mold 9 during the upper and lower mold processes.

[0045] The upper mold station 311 is located on one side of the mold changing trolley 3 and is used to carry the mold to be installed. To ensure the stability and safety of the mold during transportation and replacement, the station is equipped with a support structure and a locking device.

[0046] The lower mold station 312 is located on the other side of the mold changing trolley 3, corresponding to the upper mold station 311, and is used to carry the disassembled mold. Similarly, in order to facilitate transportation, the lower mold station 312 is also equipped with a support and locking mechanism to improve safety during transportation.

[0047] The mold station 31 of the mold-changing trolley 3 is a dual-station design. During mold changes, one station is used to hold the removed mold, while the other is used to hold the mold to be installed. This allows the replacement stamping die 9 to be prepared while the mold is being replaced, achieving seamless mold changes and significantly shortening mold change time. By reducing the waiting time for mold changes, the overall efficiency of the production line is improved.

[0048] In addition, the double-station design enables the mold-changing trolley 3 to adapt to molds of different sizes and types, enhancing the flexibility of the production line and facilitating rapid adjustment and optimization of mold specifications according to production needs.

[0049] To further improve mold-changing efficiency and production automation, the dual-station mold-changing trolley 3 can also integrate automation and intelligent technologies. For example, sensors and control systems can be installed to achieve automatic mold identification, positioning, and replacement; or robots and other automated equipment can be introduced to assist in mold handling and installation.

[0050] In order to further facilitate the replacement and transfer of the mold, the mold changing trolley 3 also includes a frame 32 and a sliding assembly arranged at the bottom of the frame 32. The sliding assembly is used to enable the mold changing trolley 3 to slide along the sliding track 42.

[0051] The sliding assembly includes a high wheel 33 and a low wheel 34 . The high wheel 33 is mounted on the sliding track 42 , and the low wheel 34 is mounted on the bottom plate 41 and in contact with the bottom plate 41 .

[0052] The high wheel 33 is mounted on the sliding track 42, bears the main weight of the sliding assembly, and forms rolling contact with the sliding track 42 to reduce friction resistance.

[0053] The low wheel 34 is mounted on the bottom plate 41 and contacts the bottom plate 41 to play the role of auxiliary support and stabilization of the sliding assembly. The design of the low wheel 34 can be adjusted according to actual working conditions to adapt to different bottom surface materials and flatness requirements.

[0054] The sliding track 42 should have enough strength and rigidity to ensure that the high wheel 33 can roll smoothly thereon. Simultaneously, the surface of the sliding track 42 should be properly processed, such as quenching, hardening, etc., to improve wear resistance.

[0055] In order to ensure smooth and stable mold transfer, the bottom plate 41 should be designed to be flat and stable to support the low wheel 34 and ensure the stability of the sliding assembly. The material and thickness of the bottom plate 41 should be selected according to the actual load and use environment.

[0056] The high wheel 33 and the low wheel 34 should be made of wear-resistant and corrosion-resistant high-performance materials, such as hard alloy, stainless steel, etc. These materials have good mechanical properties and wear resistance, and can adapt to long-term and high-intensity use requirements.

[0057] The high wheel 33 and the sliding track 42 adopt rolling contact to significantly reduce friction resistance, so that the sliding assembly can move more easily and quickly, thereby improving the operating efficiency of the entire system.

[0058] The contact between the lower wheel 34 and the base plate 41 provides additional support for the sliding assembly, enhancing its stability. Even on uneven ground or when subjected to lateral forces, the sliding assembly can maintain smooth operation.

[0059] In order to achieve rapid mold change and reduce manpower, multiple groups of rolling elements 5 are provided on the upper surface of the mold shifting slide 2 and the mold station 31. Preferably, in this embodiment, the rolling elements 5 are universal balls.

[0060] Multiple groups of rolling elements 5 are evenly distributed on the upper surface of the mold shifting slide 2 and the mold station 31. These rolling elements 5 can rotate freely in all directions, thereby greatly reducing the friction resistance between the mold shifting slide 2 and the mold station 31, making the mold shifting process smoother.

[0061] The plurality of rolling elements 5 are evenly distributed on the upper surface of the mold shifting slide 2 and the mold station 31 at a certain interval, ensuring uniform force during the mold shifting process and avoiding the occurrence of local wear or jamming.

[0062] As an optimization, a dust shield 35 is also provided on the upper surface of the mold station 31. By providing the dust shield 35 on the upper surface of the mold station 31, it is ensured that the waste cannot directly contact the gaps between the rolling elements 5.

[0063] As a further optimization, a circular hole 351 corresponding to the rolling element 5 set on the mold station 31 is opened on the dust guard plate 35. The aperture of the circular hole 351 is set to 2 mm, and the diameter of the circular hole 351 is designed to be less than or equal to the diameter of the rolling element 5, so that even if the waste passes through the hole 351, it cannot fall into the gap between the rolling elements 5, effectively preventing the accumulation of waste and damage to the mold.

[0064] In terms of dimensional design, the size and position of the circular hole 351 precisely match the rolling element 5 , thereby ensuring that the rolling element 5 can work normally without being affected by the dust shield 35 .

[0065] In this example, after the die shifting slide 2 completes the upper and lower dies, it is necessary to remove the die shifting slide 2 from between the punch press table 8 and the die change trolley 3. To facilitate the placement of the die shifting slide 2, a hanger 6 is provided on one side of the frame 32 of the die change trolley 3. The hanger 6 is fixed to the frame 32 of the die change trolley by welding or bolting, and is used to place the die shifting slide 2.

[0066] The hanger 6 uses Q235 steel as the main material, thereby ensuring that the hanger 6 has sufficient load-bearing capacity and durability.

[0067] In order to facilitate the adjustment of the position of the hanger 6 to meet the placement requirements of the mold transfer slide 2 of different specifications. In this embodiment, the hanger 6 is designed to be detachable, the hanger 6 is connected to the frame 32 by bolts, and an adjustment slot is provided on the hanger 6 for adjusting the installation height of the hanger 6.

[0068] As a further optimization, limit blocks 7 are provided at both ends of the sliding track 42. The limit blocks 7 are firmly installed at both ends of the sliding track 42 by welding, bolt connection or other fasteners to ensure that they will not loosen or fall off during use, so as to prevent the mold transfer trolley from sliding out of the sliding track 42.

[0069] In order to ensure the limiting effect, the limiting block 7 should be made of high-strength, wear-resistant materials, such as cast iron or alloy steel, to ensure that it is not easily deformed or damaged during use.

[0070] Of course, a mechanical buffer device can also be set at the end of the sliding track 42 instead of the limit block 7, such as a spring buffer or a hydraulic buffer. When the mold transfer trolley collides with the buffer device, the impact force on the mold transfer trolley is reduced through the buffering effect, thereby protecting the mold transfer trolley and the sliding track 42 from damage.

[0071] like Figure 2 As shown, the present application also records a stamping die rapid die change system, including the stamping die rapid die change mechanism described above, and a punching machine 1 and a stamping die 9 matched therewith.

[0072] The specific die changing steps of the stamping die quick die changing mechanism of this application are as follows:

[0073] Preparation stage: The stamping die 9 to be replaced is placed on the upper die station 311 of the die changing trolley 3 and ensured to be stable. At the same time, the completed die is left on the punching machine workbench 8.

[0074] Pushing in the die-changing trolley: The operator pushes the die-changing trolley 3 to the end of the punch press 1, keeping a certain distance between it and the punch press workbench 8 so as to set up the die-transfer slide 2.

[0075] Set up the die-transfer slide: Set up the die-transfer slide 2 between the punching machine worktable 8 and the die-changing trolley 3, ensuring that the slide is in close contact with the surfaces of both and in the same plane.

[0076] Pull out the old mold: By pushing the mold changing trolley 3, use the mold moving slide 2 to smoothly pull the completed mold from the punching machine workbench 8 to the lower mold station 312 of the mold changing trolley 3.

[0077] Push in the new die: Push the die changing trolley 3 again so that the upper die station 311 is aligned with the punching machine table 8. Then, push the stamping die 9 to be replaced from the die changing trolley 3 to the punching machine table 8 and fix it.

[0078] Remove the die transfer slide: After the mold enters the punch press workbench 8, the operator takes out the die transfer slide 2 and sets it up in the hanger 6 on the right side of the mold changing trolley 3 for subsequent use.

[0079] Remove the die-changing trolley: Move the die-changing trolley 3 to the other side of the punch press 1 to prepare for the next die-changing operation.

[0080] In summary, by adopting the stamping die quick die changing mechanism, the die changing process only requires one operator to operate, which is convenient and fast. The entire die changing time is controlled within 15 minutes, thereby improving production efficiency.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0082] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them; when the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
