Description

Technical Field

[0001] This invention relates to the field of stamping die technology, and more particularly to a stamping die structure and a stamping die. Background Technology

[0002] Stamping dies apply pressure to materials such as tubes and sheets, causing them to separate or undergo plastic deformation to obtain workpieces of the required size and shape. These stamped workpieces are widely used in products of various industries such as automobiles, instruments, office equipment, and home appliances. Therefore, there are inevitably industry demands for stamped workpieces with complex shapes that require multiple internal and external bends (such as petal-shaped or lotus-shaped workpieces).

[0003] However, most existing stamping dies can only process local parts of the material. If it is necessary to produce workpieces with multiple internal and external bends, such as lotus-shaped workpieces, multiple processing steps are required, which leads to cumbersome and complicated processes, resulting in low processing efficiency. Furthermore, the use of multiple processing steps can easily lead to dimensional differences in different parts of the workpiece, making it difficult to guarantee workpiece quality. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a stamping die structure and a stamping die that can improve processing efficiency and ensure processing quality.

[0005] To solve the above-mentioned technical problems, the present invention provides a stamping die structure, including a workpiece, a support base, and a stamping base located above the support base. The workpiece includes an interconnected fixing part and a machining part. The fixing part is engaged with the support base, and the machining part faces the stamping base. The present invention is characterized in that...

[0006] The stamping base is provided with a shaping disc and a shaping ring surrounding the shaping disc. The stamping base can move toward the support base so that the shaping disc is close to the inner surface of the processing part and the shaping ring is close to the outer surface of the processing part.

[0007] The support base is provided with an expansion ring near the outside of the processing part. The inner wall of the expansion ring is provided with a first protrusion and a first groove that are distributed circumferentially and staggered from each other. The outer wall of the shaping plate is provided with a second protrusion and a second groove that are distributed circumferentially and staggered from each other. The first protrusion and the second protrusion are staggered, and the first groove and the second groove are staggered.

[0008] The shaping ring is fitted onto the expansion ring and pushes the expansion ring to contract toward the processing part, so that the first protrusion and the second groove cooperate to bend one part of the processing part inward, and the second protrusion and the first groove cooperate to bend the other part of the processing part outward.

[0009] Preferably, a first shaping block is slidably connected to the support base, and the first shaping block is closely arranged along the circumference of the shaping disk to form the expansion and contraction ring;

[0010] The first shaping block is provided with the first protrusion and the first recess on both sides of the first protrusion, and the first groove is formed by combining the first recess.

[0011] Preferably, the stamping die structure further includes a sliding member, and the support base has guide rail grooves arranged at intervals along the circumference of the shaping plate. The first shaping block is connected to the guide rail groove through the sliding member, so that the first shaping block can move closer to or away from the outside of the processing part along the guide rail groove.

[0012] Preferably, the support base is further provided with a positioning groove that overlaps with the position of the shaping plate, the fixing part is locked in the positioning groove, the guide rail groove is arranged around the positioning groove, and one end of the guide rail groove is close to the positioning groove.

[0013] The slider and one end of the guide rail groove are connected by a spring.

[0014] Preferably, the inner wall of the shaping ring is inclined inward from bottom to top, and the first shaping block is provided with a transmission inclined surface facing the inner wall. The inclination direction of the transmission inclined surface is consistent with the inclination direction of the inner wall of the shaping ring, so that the inner wall of the shaping ring can abut against the transmission inclined surface and push the first shaping block closer to the outside of the processing part.

[0015] Preferably, the inner wall of the shaping ring is provided with limiting grooves arranged at intervals along its circumference, the position of the limiting grooves corresponds to the position of the first shaping block, and the transmission inclined surface is provided with limiting blocks, the limiting blocks being locked in the limiting grooves.

[0016] Preferably, the shaping disc includes a mounting post and second shaping blocks arranged closely around the circumference of the mounting post. The mounting post is connected to the stamping seat, and the mounting post and the second shaping blocks are inserted together into the positioning groove.

[0017] The second shaping block is provided with a second protrusion and a second recess located on both sides of the second protrusion, and the second groove is formed by combining the second recesses.

[0018] Preferably, the second shaping block is further provided with a positioning part located below the second protrusion, and the positioning part cooperates with the inner wall of the positioning groove to clamp the fixing part;

[0019] The bottom surface of the positioning groove is provided with a connecting block, and the bottom of the positioning part is provided with a connecting groove. The positioning part is fitted onto the connecting block through the connecting groove.

[0020] Preferably, the support base is provided with a first connecting post, and the stamping base is provided with a second connecting post corresponding to the position of the first connecting post. The first connecting post and the second connecting post are connected to each other so that the support base and the stamping base are connected.

[0021] On the other hand, the present invention provides a stamping die, including the above-described stamping die structure.

[0022] Implementing the embodiments of the present invention has the following beneficial effects:

[0023] This invention features a forming disc and a forming ring surrounding the forming disc on the stamping base. The stamping base can move towards the support base, bringing the forming disc closer to the inner surface of the processing part and the forming ring closer to the outer surface of the processing part. Through the cooperation of the forming disc and the forming ring, the bending effect of the entire processing part of the workpiece can be completed in a single processing step, thereby improving processing efficiency, eliminating the need for multiple processing steps, minimizing dimensional differences between different parts of the processing part, and ensuring processing quality.

[0024] Specifically, the support base is provided with an expansion ring near the outside of the processing part. The expansion ring can expand to move away from the processing part or contract to move closer to the processing part. The inner wall of the expansion ring is provided with a first protrusion and a first groove distributed circumferentially and staggered from each other. The outer wall of the shaping disc is provided with a second protrusion and a second groove distributed circumferentially and staggered from each other. The first protrusion and the second protrusion are staggered, and the first groove and the second groove are staggered. So that when the expansion ring contracts to move closer to the processing part, the first protrusion can cooperate with the second groove, and the second protrusion can cooperate with the first groove, so as to realize the bending function of the processing part.

[0025] Furthermore, the shaping ring moves together with the stamping seat and is fitted onto the expansion ring, causing the shaping ring to push the expansion ring to contract towards the processing part. This allows the first protrusion and the second groove to cooperate in bending one part of the processing part inward, and the second protrusion and the first groove to cooperate in bending the other part of the processing part outward. This achieves a bending effect on the entire processing part, ensuring that there are no dimensional differences between the various parts of the processing part and ensuring processing quality.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0035] Combination Figures 1 to 8 According to one embodiment of the present invention, a stamping die structure is provided, including a workpiece 1, a support base 2 and a stamping base 3 located above the support base 2. The workpiece 1 includes an interconnected fixing part 11 and a processing part 12. The fixing part 11 is locked on the support base 2 to ensure that the workpiece 1 is installed firmly. The processing part 12 faces the stamping base 3 in order to achieve the processing effect.

[0036] The present invention provides a shaping disc 31 and a shaping ring 32 surrounding the shaping disc 31 on the stamping base 3. The stamping base 3 can move towards the support base 2, so that the shaping disc 31 is close to the inner surface of the processing part 12 and the shaping ring 32 is close to the outer surface of the processing part 12. Through the cooperation of the shaping disc 31 and the shaping ring 32, the bending effect of the entire processing part 12 of the workpiece 1 can be completed in a single processing, thereby improving processing efficiency, eliminating the need for multiple processing, and preventing dimensional differences between the parts of the processing part 12, thus ensuring processing quality.

[0037] Specifically, the support base 2 is provided with an expansion ring 4 near the outside of the processing part 12. The expansion ring 4 can expand to move away from the processing part 12 or contract to move closer to the processing part 12. The inner wall of the expansion ring 4 is provided with a first protrusion 411 and a first groove 412 that are distributed circumferentially and staggered from each other. The outer wall of the shaping disk 31 is provided with a second protrusion 311 that is distributed circumferentially and staggered from each other. The first protrusion 411 and the second protrusion 311 are staggered, and the first groove 412 and the second groove 312 are staggered. So when the expansion ring 4 contracts to move closer to the processing part 12, the first protrusion 411 can cooperate with the second groove 312, and the second protrusion 311 can cooperate with the first groove 412 to realize the bending function of the processing part 12.

[0038] Furthermore, the shaping ring 32 moves together with the stamping seat 3 and is fitted onto the expansion ring 4, causing the shaping ring 32 to push the expansion ring 4 to contract towards the processing part 12. This causes the first protrusion 411 and the second groove 312 to cooperate in bending one part of the processing part 12 inward, and the second protrusion 311 and the first groove 412 to cooperate in bending the other part of the processing part 12 outward. This achieves a bending effect on the entire processing part 12, ensuring that there are no dimensional differences between the parts of the processing part 12 and ensuring processing quality.

[0039] It should be noted that when the shaping ring 32 moves in the opposite direction along with the stamping seat 3 and moves away from the expansion ring 4, the expansion ring 4 will expand to move away from the processing part 12, which will prevent the workpiece 1 from sticking tightly to the expansion ring 4 and being difficult to remove, thereby further improving processing efficiency.

[0040] Furthermore, combining Figures 2 to 8 To achieve the expandable and contractible function of the expansion and contraction ring 4, a first shaping block 41 is slidably connected to the support base 2. The first shaping block 41 is closely arranged along the circumference of the shaping disk 31 to form the expansion and contraction ring 4. By slidingly connecting the first shaping block 41 to the support base 2, the first shaping block 41 can move closer to or further away from the outside of the processing part 12, thereby realizing the expansion and contraction function of the expansion and contraction ring 4. Furthermore, by closely arranging the first shaping block 41 along the circumference of the shaping disk 31, the first shaping block 41 can cooperate with the shaping disk 31 to achieve the overall bending function of the processing part 12 of the workpiece 1, and can be formed in one step, thereby improving processing efficiency and ensuring processing quality.

[0041] The first shaping block 41 has a first protrusion 411 and first recesses 413 located on both sides of the first protrusion 411. The first groove 412 is formed by combining the first recesses 413 to achieve the function of cooperating with the second protrusion 311 and the second groove 312 on the shaping plate 31. It should be noted that the operator can add or remove the first shaping block 41 according to actual needs, or replace one or more of the first shaping blocks 41 with shaping modules of other shapes, so that the processing part 12 can be processed into various different shapes, thereby improving the versatility of this stamping die.

[0042] Preferably, to enable the first shaping block 41 to move, the stamping die structure further includes a sliding member 42. The support base 2 has guide grooves 21 spaced circumferentially along the shaping disk 31. The first shaping block 41 is connected to the guide grooves 21 via the sliding member 42, allowing the first shaping block 41 to move closer to or further away from the outside of the processing section 12 along the guide grooves 21. It should be noted that, for ease of setting the guide grooves 21, the support base 2 can be a boss structure.

[0043] Furthermore, the support base 2 is also provided with a positioning groove 22 that overlaps with the position of the shaping plate 31. The fixing part 11 of the workpiece 1 is stuck in the positioning groove 22 and plays a positioning role. The guide rail groove 21 is arranged around the positioning groove 22, and one end of the guide rail groove 21 is close to the positioning groove 22 to ensure that the first shaping block 41 can move closer to or away from the outside of the processing part 12 along the guide rail groove 21.

[0044] More preferably, to achieve the driving function of the shaping ring 32 on the expansion and contraction ring 4, the inner wall of the shaping ring 32 is inclined inward from bottom to top, and the first shaping block 41 is provided with a transmission inclined surface 414 facing the inner wall. The inclination direction of the transmission inclined surface 414 is consistent with the inclination direction of the inner wall of the shaping ring 32, so that the inner wall of the shaping ring 32 can abut against the transmission inclined surface 414 and push the first shaping block 41 closer to the processing part 12, so as to achieve the function of the shaping ring 32 pushing the expansion and contraction ring 4 to contract towards the processing part 12, and ensuring the bending function of the processing part 12.

[0045] It should be noted that the sliding member 42 and one end of the guide rail groove 21 are connected by a spring member 43. When the shaping ring 32 moves away from the expansion and contraction ring 4 composed of each first shaping block 41, the spring member 43 can push each first shaping block 41 to spring back and reset, so as to realize the function of automatic reset and expansion of the expansion and contraction ring 4.

[0046] More preferably, to further ensure processing quality, the inner wall of the shaping ring 32 is provided with limiting grooves 321 arranged at intervals along its circumference. The position of the limiting grooves 321 corresponds to the position of the first shaping block 41. The transmission inclined surface 414 is provided with limiting blocks 415. The limiting blocks 415 are locked in the limiting grooves 321 to limit the first shaping blocks 41 and ensure that each first shaping block 41 can approach the processing part 12 together to process each part of the processing part 12 at the same time, ensuring that the parts of the processing part 12 are not prone to dimensional differences.

[0047] On the other hand, combining Figures 2 to 7 To enable the shaping disc 31 to cooperate with the expansion ring 4, the shaping disc 31 includes a mounting post 313 and second shaping blocks 314 closely arranged circumferentially along the mounting post 313. The mounting post 313 is connected to the stamping base 3, allowing the shaping disc 31 to move together with the stamping base 3. The second shaping block 314 has a second protrusion 311 and second recesses 315 located on both sides of the second protrusion 311. The second groove 312 is formed by combining the second recesses 315 to achieve the function of cooperating with the first protrusion 411 and the first groove 412 on the expansion ring 4. It should be noted that the operator can add or remove the second shaping blocks 314 according to actual needs, or replace one or more of the second shaping blocks 314 with shaping modules of other shapes, so that the processing part 12 can be processed into various different shapes, thereby improving the versatility of this stamping die.

[0048] The mounting post 313 and the second shaping block 314 are inserted together into the positioning groove 22 to limit the movement and allow the second shaping block 314 to cooperate with the inner wall of the positioning groove 22 to clamp the fixing part 11, thus ensuring the fixing effect on the workpiece 1.

[0049] Preferably, the second shaping block 314 is further provided with a positioning part 316 located below the second protrusion 311. The positioning part 316 cooperates with the inner wall of the positioning groove 22 to clamp the fixing part 11, thereby further ensuring the fixing effect of the fixing part 11.

[0050] More preferably, the bottom surface of the positioning groove 22 is provided with a connecting block 23, and the bottom of the positioning part 316 is provided with a connecting groove 317. The positioning part 316 is fitted onto the connecting block 23 through the connecting groove 317 to play a positioning role, ensuring that the support and the stamping seat 3 are accurately combined together, and ensuring the precision of processing.

[0051] It should be noted that the connecting block 23 may also be provided with a connecting rod 231, and the connecting groove 317 is provided with a positioning hole 318. The connecting rod 231 is inserted into the positioning hole 318 to further play a positioning role and further ensure that the seat and the stamping seat 3 are accurately combined together.

[0052] In addition, to ensure a stable connection during processing, the support base 2 is provided with a first connecting post 24, and the stamping base 3 is provided with a second connecting post 33 corresponding to the position of the first connecting post 24. The first connecting post 24 and the second connecting post 33 are connected so that the support base 2 and the stamping base 3 are connected during processing, ensuring that the support base 2 is not prone to displacement or bending, and further ensuring the accuracy of processing.
