[0048] In order to more clearly illustrate the overall concept of the present application, the following will be described in detail with reference to the accompanying drawings.

[0049] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can be practiced in other manners different from those described herein, and therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below. It should be noted that the embodiments of the present application and the features in each embodiment can be combined with each other without conflict.

[0050] As​​​Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 As shown, a stamping die device includes an upper die base 1 and a lower die base 2. A support frame 3 for placing a stamped object 5 is provided between the upper die base 1 and the lower die base 2. The lower die base 2 is also provided with a forming part 21. The support frame 3 is provided with a clearance hole 31 to avoid the forming part 21. The upper die base 1 moves relative to the lower die base 2 so that the stamped object 5 abuts against the forming part 21. The upper die base 1 and / or the lower die base 2 have a reset state that returns to the initial position. The stamping die device is provided with a plurality of mounting brackets 4 spaced apart around the support frame 3. The mounting brackets 4 are connected to the lower die base 2 through telescopic members 6. In the reset state, the telescopic members 6 abut against the mounting brackets 4 or the lower die base 2 so that the support frame 3 drives the stamped object 5 to move toward the side away from the lower die base 2.

[0051] This application provides stable support to the support frame 3 by arranging multiple mounting brackets 4 at intervals around its circumference. This allows the support frame 3 to distribute the force evenly around its perimeter, improving its load-bearing capacity and enabling it to support large stamped objects 5. This also makes the movement of the support frame 3 more stable. Furthermore, the support frame 3 can accommodate a wider range of stamped object sizes 5. In a preferred embodiment, after changing the product model of the stamped object 5, the support frame 3 can be replaced simply by disassembling the mounting brackets 4 and the telescopic component 6, making the replacement process simple and easy. The circumferential mounting brackets 4 allow the user to walk around the support frame 3 to check the status of the telescopic component 6, facilitating inspection and replacement and optimizing the workflow for replacing the telescopic component 6. By connecting the mounting brackets 4 to the lower die base 2 via the telescopic component 6, after stamping, in the reset state, the telescopic component 6 moves the support frame 3, allowing the stamped object 5 to disengage from the formed part 21. This facilitates the removal of the stamped object 5 by the operator, allowing the stamping die device to proceed to the next stamping operation more quickly.

[0052] In this application, the telescopic member 6 can be fixed in any of the following embodiments:

[0053] Implementation method one: such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, one of the lower mold base 2 and the mounting bracket 4 is provided with a guide hole 22, and the other is provided with a moving part 41 that cooperates with the guide hole 22. The moving part 41 can move axially along the guide hole 22. The telescopic part 6 is provided in the guide hole 22. The telescopic part 6 abuts against the moving part 41 so that the support frame 3 drives the stamped object 5 to move toward the side away from the lower mold base 2.

[0054] By providing guide hole 22 and moving part 41, the moving part 41 can move axially along guide hole 22. On the one hand, it guides the movement of the support 3, further improving the stability of the movement of the support 3, so that the stamped object 5 can accurately abut against the formed part 21, improving the stamping accuracy of the stamped object 5. At the same time, the moving part 41 can move axially along guide hole 22 to prevent the support 3 from lateral displacement under force. On the other hand, by providing moving part 41 and guide hole 22, it is also convenient to install and position the support 3. Moreover, the cooperation between guide hole 22 and moving part 41 can offset the impact of stamped object 5 on the support 3 in the non-guide hole 22 axial direction when it enters and exits the support 3, so that the support 3 can be kept in the set position.

[0055] Implementation Method 2: This implementation method is not illustrated. One of the mounting bracket and the lower mold base is provided with a positioning groove, and the telescopic component is fixed in the positioning groove.

[0058] By setting the positioning element 43 to be located on the side of the connecting element 42 away from the support frame 3, the vertical space occupied by the mounting bracket 4 on the support frame 3 is reduced, which facilitates the movement of the stamped object 5. The positioning element 43 is provided with a guide hole 22 or a moving element 41 at one end facing the lower mold base 2, and the upper mold base 1 is provided with an abutment element 11 of the positioning element 43. The upper mold base 1 drives the support frame 3 to move by abutting against the abutment element 11, avoiding direct force on the support frame 3, avoiding force concentration on the support frame 3, and extending the service life of the support frame 3. Moreover, direct contact with the positioning element 43 facilitates the driving of the connecting element 42 to move axially along the guide hole 22, optimizing the force direction of the positioning element 43.

The moving member 41 abuts against the telescopic member 6, and the telescopic member 6 is elastically deformed, which on the one hand plays a buffering role to stabilize the movement of the object supporting rack 3, and on the other hand accumulates elastic potential energy to drive the moving member 41 to move the object supporting rack 3 after the movement of the upper die seat 1. The elastic member has simple structure, is convenient to replace and maintain, can reduce weight and cost, and through the containing hole 411, the telescopic member 6 is convenient to install and position, and through the telescopic member 6 partially exposed from the containing hole 411, the elastic deformation of the telescopic member 6 is facilitated.

[0081] As a preferred specific example 7 of embodiment 5, as shown in Figure 4 , Figure 11As shown, a stopper 221 is also provided inside the guide hole 22 to stop the telescopic member 6. By setting the stopper 221, the length requirement of the telescopic member 6 can be reduced, and the stopper 221 can be accurately aligned with the telescopic member 6, so that the force-bearing part of the telescopic member 6 is accurate.

[0082] Example 6: This example 6 is not shown in the figure. The telescopic component is an elastic component. A clamping component for holding the elastic component is provided at the bottom of the guide hole. The elastic component abuts against the moving component.

[0083] As a preferred embodiment of this application: (e.g.) Figure 3 , Figure 4 , Figure 8 , Figure 11 As shown, one of the lower die base 2 and the mounting bracket 4 is provided with a guide hole 22, and the other is provided with a moving part 41 that cooperates with the guide hole 22. The moving part 41 can move axially along the guide hole 22. The telescopic part 6 is set in the guide hole 22 and abuts against the moving part 41 to make the support 3 drive the stamped object 5 to move away from the lower die base 2. The guide hole 22 is also provided with a guide sleeve (not shown in the figure) that cooperates with the moving part 41. By setting the guide sleeve, the friction between the moving part 41 and the guide hole 22 is reduced, making the movement of the moving part 41 smoother and more stable. The guide sleeve can guide the movement of the guide column more precisely and improve the movement accuracy. As a buffer layer between the moving part 41 and the guide hole 22, the guide sleeve can withstand the wear between the moving part 41 and the guide hole 22. The guide sleeve can be directly replaced in the future, which is convenient for replacement and maintenance.

[0084] In this application, the method of setting the stamped material 5 to enter and exit can be any of the following embodiments:

[0085] Implementation Method Four: (e.g.) Figure 8 As shown, along the direction of entry of stamped material 5 ( Figure 8 In the vertical direction, the mounting brackets 4 set on the front and rear sides of the shelf 3 are positioning mounting brackets. Guide wheels 7 are set on both sides of the positioning mounting brackets along the direction of entry of the stamped object 5. The guide wheels 7 face the direction of entry of the stamped object 5, and the top of the guide wheels 7 is higher than the top of the positioning mounting bracket and the top of the shelf 3.

[0086] By providing guide wheels 7 on both sides of the positioning mounting bracket, with the height of the guide wheels 7 being higher than the height of the positioning mounting bracket and the guide wheels 7 facing the direction of the stamped object 5 entering and exiting, the guide wheels 7 can contact the stamped object 5 first to guide the stamped object 5 into the shelf 3 during the process of the stamped object 5 entering and exiting the shelf 3, thus avoiding hard contact between the stamped object 5 and the positioning mounting bracket and protecting the positioning mounting bracket.

[0087] As a preferred embodiment 7 of implementation method four: Figure 8 , Figure 9As shown in the figure, the guide wheel 7 includes a support 71 connected with the lower die holder 2 and a roller 72 connected with the support 71, and the support 71 can abut against the stamping object 5. Those skilled in the art can clearly see that the direction of the stamping object 5 moving in and out can also be further limited by setting a limiting plate on the lower die holder 2. By setting the support 71 abutting against the stamping object 5, the supports 71 located on both sides of the object supporting frame 3 provide positioning for the stamping object 5 moving in, and when the stamping object 5 moves to the position of the support 71 and abuts against the support 71, the stamping object 5 is prevented from leaving the supporting range of the object supporting frame 3.

[0088] As a preferred embodiment 8 of the fourth embodiment, as shown in the figure, Figure 8 、 Figure 9 As shown in the figure, the object supporting frame 3 is also provided with a plurality of support guide wheels 32 at intervals, and the support guide wheels 32 are towards the entering direction of the stamping object 5. By setting the support guide wheels 32, the support guide wheels 32 are towards the entering and leaving direction of the stamping object 5, the stamping object 5 first passes through the guide wheel 7 to enter the object supporting frame 3, and then contacts the support guide wheel 32, further improving the smoothness of the stamping object 5 entering and leaving the object supporting frame 3, and reducing the impact of the stamping object 5 on the object supporting frame 3, avoiding hard contact between the stamping object 5 and the object supporting frame 3, and preventing the stamping object 5 and the object supporting frame 3 from being damaged.

[0089] As a preferred, the object supporting frame 3 is also provided with a plurality of damping blocks (not shown in the figure) arranged at intervals, and the top end of the damping block is flush with the top end of the roller 72. By setting the damping block, the top end of the damping block is flush with the top end of the roller 72, which not only ensures that the stamping object 5 can move smoothly under the low friction of the roller 72, but also can appropriately slow down or position the stamping object 5 when necessary, such as when the stamping object 5 enters the object supporting frame 3 or the object supporting frame 3 tilts due to failure. Moreover, the die device will vibrate during the stamping process, and the damping block can absorb part of the vibration energy, preventing the stamping object 5 from being displaced due to vibration, thereby ensuring the stability and precision of the stamping process.

[0090] The fifth embodiment: the fifth embodiment is not shown, and the difference from the fourth embodiment is that the relatively high top end between the positioning installation support and the object supporting frame is flush with the top end of the guide wheel.

[0091] In this application, the object supporting frame 3 can be any of the following embodiments:

[0092] The sixth embodiment: as shown in the figure, Figure 3 、 Figure 4 、 Figure 8As shown, the object supporting rack 3 comprises a plurality of staggered horizontal bars 33 and longitudinal bars 34, the horizontal bars 33 and the longitudinal bars 34 form the avoiding hole 31, and the lower die seat 2 is circumferentially spaced apart from the avoiding hole 31 and is provided with a plurality of auxiliary elastic members 24 for abutting with the horizontal bars 33 and the longitudinal bars 34. By arranging the staggered horizontal bars 33 and the longitudinal bars 34, the horizontal bars 33 and the longitudinal bars 34 form a stable frame structure, which has sufficient carrying capacity and can reduce the weight of the object supporting rack 3. By arranging the auxiliary elastic members 24, the horizontal bars 33 and the longitudinal bars 34 can be supported, so that the horizontal bars 33 and the longitudinal bars 34 forming the avoiding hole 31 can disperse the force, and ensure that the structure of the entire object supporting rack 3 is uniformly stressed.

[0093] Embodiment seven: this embodiment seven is not shown, the object supporting rack is a plate structure, and the avoiding hole is formed at a fixed position by a cutting process.
