Description

Technical Field

[0001] This utility model relates to the field of progressive die manufacturing technology, and in particular to a guide float structure and stamping equipment. Background Technology

[0002] Progressive dies, also known as stamping dies, are a type of die used in stamping processes. They allow strip or bar stock to pass sequentially through multiple stations, progressively completing various processes such as punching, blanking, bending, and drawing, ultimately forming the desired part. During progressive die stamping, the feeding device has coarse positioning errors. The strip stock may deform during stamping, sticking tightly to the die surface or moving vertically, leading to insufficient part precision, strip damage, or die failure. To solve these problems, auxiliary components such as guide pins, float pins, and limit pins are needed in the die to optimize the strip stock's movement from three dimensions: horizontal positioning, strip support, and vertical limiting, thus meeting the requirements of high-volume precision stamping for accuracy, efficiency, and die life.

[0003] Currently, there are some guide float structures that have limit pins and float pins spaced apart on the lower template along the direction of the material to be processed, and guide pins on the upper template. The guide pins pass through the material to be processed and are inserted into the float pins. However, when using the guide float structure, there are problems such as complex structure, large number of parts, difficult assembly and debugging, and large space occupation.

[0004] Therefore, there is an urgent need for a guiding float structure that can solve the problems of complex guiding float structures, numerous parts, and large space occupation. Utility Model Content

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0007] A guide float structure is used to guide and limit the material to be processed. The guide float structure includes:

[0008] A template assembly includes an upper template and a lower template spaced apart vertically, a strip to be processed is placed between the upper template and the lower template, a guide hole is provided on the edge of the strip to be processed, and an installation hole is provided on the lower template.

[0009] A guide pin, at least a portion of which is accommodated within the upper template, is connected to the upper template, and extends downward;

[0010] A guide float pin is provided corresponding to the guide pin. At least part of the guide float pin is inserted into the mounting hole. The guide float pin extends upward and includes a head, a neck and a body connected sequentially from top to bottom. The cross-sectional area of ​​the neck is smaller than that of the head and the body.

[0011] As an optional solution for the guide float structure, the guide float pins are arranged in two rows at intervals along the left and right direction, and each row of the guide float pins extends along the front and back direction. The material to be processed is arranged inside the two rows of guide float pins, and the guide hole is arranged at one of the opposite inner ends of the guide float pins along the left and right direction.

[0012] As an alternative to the guide float structure, the guide hole extends through the guide float pin in the vertical direction.

[0013] As an alternative to the guide float structure, the neck extends inward in the left-right direction with a dimension smaller than the head and the main body, and the main body extends inward in the left-right direction with a dimension smaller than the head.

[0014] As an alternative to the guide float structure, there is a smooth transition between the head and the neck, and a smooth transition between the neck and the main body.

[0015] As an alternative to the guide float structure, the guide float structure also includes an elastic element disposed directly below the guide float pin.

[0016] As an alternative to the guide float structure, the inner diameter of the guide hole is greater than or equal to the outer diameter of the guide pin.

[0017] As an alternative to this guide float structure, the lower end of the guide pin is tapered.

[0018] As an alternative to the guide float structure, the guide float pin also includes an extension portion, which is formed by the portion of the main body disposed in the mounting hole extending outward relative to the portion of the main body above the upper surface of the lower template.

[0019] The template assembly also includes a corresponding positioning block and a positioning groove. The positioning block is provided on the upper surface of the lower template and is located on the outside of the main body.

[0020] A stamping device includes a pressing structure, a stretching structure, and a guide float structure. The pressing structure is connected to an upper template, the stretching structure is disposed in front of the guide float structure, and the stretching structure is connected to the strip to be processed.

[0021] The beneficial effects of this utility model are as follows:

[0022] This utility model proposes a guide float structure. The template assembly includes an upper template and a lower template spaced apart vertically. The strip to be processed is placed between the upper and lower templates. At least a portion of the guide pins are accommodated in the upper template and connected to it, extending downwards.

It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] This embodiment provides a stamping device applicable to automobile manufacturing, electronics manufacturing, and aerospace fields for stamping and forming of strip materials. In this embodiment, the stamping device includes a pressing structure, a stretching structure, and a guiding float structure. The pressing structure is connected to the guiding float structure, and the stretching structure is located in front of the guiding float structure and connected to the strip material to be processed. The pressing structure provides pressure to the guiding float structure, the stretching structure pulls the strip material to be processed, ensuring its precise entry into the processing area, and the guiding float structure ensures smooth and accurate positioning of the strip material during movement. The three components work together to achieve automated and continuous stamping of the strip material, efficiently forming complex-shaped parts.

[0040] It should be noted that the pressing structure is an existing structure. Setting a pressing structure in a stamping equipment is a conventional setting in this field. In this embodiment, any connection method in the prior art can be used to connect the guide float structure and the pressing structure, as long as it can provide pressure to the upper template 11. No further details will be provided.

[0041] It should be noted that the stretching structure is an existing structure, and setting a stretching structure in a stamping equipment is a conventional setting in this field. In this embodiment, any connection method in the prior art can be used to connect the strip to be processed to the stretching structure, as long as it can move the strip to be processed. No further details will be provided.

[0042] In some existing guide float structures, the functions of guiding, directing and limiting the material to be processed are all independent individual parts. Each part is located around the material to be processed, which leads to the problem of complex guide float structure, large number of parts and large space occupation.

[0043] To address the issues of complex guiding float structures, numerous parts, and large space requirements, such as... Figures 1-2As shown, in this embodiment, the guide float structure includes a template assembly 1, guide pins 2, and guide float pins 3. The template assembly 1 includes an upper template 11 and a lower template 12 spaced apart vertically. The strip to be processed is placed between the upper template 11 and the lower template 12. Guide holes are provided on the edges of the strip to be processed. At least a portion of the guide pins 2 are disposed within the upper template 11 and are connected to the upper template 11. The guide pins 2 extend downward. The guide float pins 3 are correspondingly disposed with the guide pins 2. At least a portion of the guide float pins 3 are disposed within the lower template 12 and extend upward. The guide float pins 3 include a head 31, a neck 32, and a main body 3 connected sequentially from top to bottom. 3. The cross-sectional area of ​​the neck 32 is smaller than that of the head 31 and the main body 33. A guide hole 34 is provided on the head 31. The guide pin 2 can pass through the guide hole and be inserted into the guide hole 34. The strip to be processed can be accommodated in the groove formed by the head 31, neck 32 and main body 33, so that the strip to be processed is limited. The guide pin 2 can be inserted into the guide hole 34, so that the strip to be processed does not deviate. The above configuration achieves the functions of limiting and guiding the strip to be processed by setting the guide floating pin 3. It simplifies the overall structure of the guide floating structure, reduces the number of parts and assembly processes, reduces costs while improving production efficiency, and ensures the processing accuracy and processing stability of the strip.

[0044] Preferably, such as Figures 1-3 As shown, in this embodiment, two rows of guide float pins 3 are spaced apart along the left and right directions. Each row of guide float pins 3 extends along the front and back directions. The strip to be processed is placed inside the two rows of guide float pins 3. The guide hole 34 is placed at one of the relatively inner ends of the guide float pins 3 along the left and right directions. This layout can accurately position and constrain the strip to be processed from the left and right and front and back directions, so that the strip remains stable during processing and is not prone to lateral or longitudinal deviation. Through the above reasonable spatial arrangement and structural design, the limiting and guiding effect of the guide float pins 3 on the strip is further strengthened, the processing accuracy and stability are improved, the structure is simplified, the number of parts and assembly processes are reduced, the cost is reduced and the production efficiency is improved.

[0045] Preferably, such as Figures 1-3As shown, in this embodiment, eight guide float pins 3 are provided, and eight corresponding guide pins 2 are provided. Four guide float pins 3 are spaced apart in each row along the front-to-back direction. Two guide float pins 3 at corresponding positions in two rows along the front-to-back direction form a group of guide float pins 3. Each group of guide float pins 3 is spaced apart in the left-to-right direction, thus achieving a rectangular array arrangement. The strip to be processed is placed inside the rectangle formed by the eight guide float pins 3. Through the multi-point constraint of the rectangular array, the twisting or lateral displacement of the strip during processing is effectively suppressed. A good constraint effect is achieved with fewer parts, simplifying the structural design and significantly improving the processing accuracy, stability, and production efficiency of the strip, while reducing costs. In other embodiments, six, seven, nine, or ten guide float pins 3 can be provided, as long as the constraint of the strip to be processed can be achieved.

[0046] Preferably, such as Figures 1-3 As shown, in this embodiment, the guide hole 34 passes through the guide float pin 3 in the vertical direction, realizing the coaxial constraint of the strip to be processed, the guide float pin 3 and the guide pin 2 in the vertical direction. When the guide pin 2 is inserted into the through guide hole 34, it can effectively limit the lateral sway of the guide float pin 3 itself, thereby improving the positioning accuracy of the strip edge.

[0047] Preferably, such as Figures 1-5 As shown, in this embodiment, the dimension of the neck 32 extending inward in the left-right direction is smaller than that of the head 31 and the main body 33, and the dimension of the main body 33 extending inward in the left-right direction is smaller than that of the head 31. The wider dimension of the head 31 can effectively cover the edge of the strip to be processed, preventing the strip from coming off from above. The size design of the neck 32 ensures that the strip can be smoothly placed into the groove surrounded by the head 31, neck 32 and main body 33. The groove surrounded by the head 31, neck 32 and main body 33 will have gaps with the two sides of the strip to be processed in the up-down direction. These gaps will form an elastic buffer, reducing the frictional resistance between the strip and the guide float pin 3. The structure of the main body 33 being slightly wider than the neck 32 enhances the overall stability of the guide float pin 3. This layered limiting method not only achieves reliable constraint on the strip, but also reduces the risk of jamming during the movement, and improves the smoothness of feeding and processing accuracy.

[0048] Preferably, such as Figures 1-5As shown, in this embodiment, the head 31 and neck 32 have a smooth transition, and the neck 32 and main body 33 have a smooth transition. This can effectively reduce stress concentration and prevent the guide float pin 3 from cracking or even breaking due to stress concentration during the stamping process. This significantly improves its structural strength and service life. The smooth transition surface can greatly reduce the frictional resistance between the strip to be processed and the guide float pin 3, making the strip move more smoothly in the groove, reducing wear on the strip surface, and preventing the strip from affecting the processing accuracy and product quality due to jamming, scratches, and other problems. This ensures the stable conveying and efficient processing of the strip to be processed.

[0049] Preferably, such as Figures 1-5 As shown, in this embodiment, the guide float structure also includes an elastic element 4, which is located directly below the guide float pin 3. The elastic element 4 can automatically provide upward support force to the material strip to be processed through elastic deformation when the upper template 11 moves upward, so that the material strip to be processed floats smoothly and achieves automatic floating. The above setting not only makes the floating process of the material strip to be processed without manual intervention, greatly improving the degree of production automation, but also ensures that the material strip to be processed is subjected to uniform and stable force during the floating process, avoiding skew or jamming, effectively preventing material damage, ensuring processing accuracy, and the automatic floating function can also cooperate with the limiting and guiding effect of the guide float pin 3 to form a continuous and efficient processing flow.

[0050] Optionally, such as Figures 1-5 As shown, in this embodiment, the elastic element 4 is a spring. When the upper template 11 moves upward, the spring automatically provides a stable and continuous upward support force through compression and rebound, precisely controlling the smooth floating of the strip to be processed, thus achieving automatic material floating. As a mature elastic element, the spring has a simple structure, low cost, and is easy to install and replace, effectively reducing the manufacturing and maintenance costs of the guide floating structure. The spring can also closely cooperate with the mold opening and closing actions, seamlessly connecting the floating and pressing processes of the strip, improving the continuity of the production rhythm, greatly enhancing production efficiency, and effectively ensuring the stability and high efficiency of strip processing. In other embodiments, the elastic element 4 can also be a polyurethane elastomer or an elastic rubber block, as long as it can achieve automatic material floating.

[0051] Preferably, such as Figures 1-6 As shown, in this embodiment, the inner diameter of the guide hole 34 is greater than or equal to the outer diameter of the guide pin 2. This allows the guide pin 2 and the guide float pin 3 to guide the processed strip while simultaneously achieving precise positioning of the strip between the upper and lower templates 12. This avoids jamming or wear problems caused by interference fit, ensuring the processing accuracy of the strip while extending the service life of the guide pin 2 and the guide float pin 3, further improving production efficiency and processing stability. More specifically, in this embodiment, the inner diameter of the guide hole 34 is equal to the outer diameter of the guide pin 2, achieving precise positioning of the strip between the upper and lower templates 12 with zero clearance.

[0052] Preferably, such as Figures 1-5 As shown, in this embodiment, the lower end of the guide pin 2 is tapered, which allows the guide pin 2 to be more easily, quickly, and accurately aligned with the hole position when inserted into the guide hole of the strip to be processed and the guide hole 34 of the head 31 of the guide float pin 3, thanks to the guiding effect of the tapered structure. This reduces the probability of difficulty or inability to insert due to hole position deviation. The tapered lower end of the guide pin 2 improves the assembly efficiency of the guide pin 2 with the strip to be processed and the guide float pin 3, and also reduces the wear on the parts during the assembly process, extends the service life of the parts, and ensures that the strip to be processed can be accurately positioned during the guidance process, further improving the processing accuracy and processing stability of the strip.

[0053] Specifically, such as Figures 1-6 As shown, in this embodiment, the guide float pin 3 further includes an extension 35, which is formed by the portion of the main body 33 disposed within the mounting hole 13 extending outward relative to the portion of the main body 33 located above the upper surface of the lower template 12. The template assembly 1 also includes a correspondingly disposed positioning block 14 and positioning groove 15. The positioning block 14 is disposed on the upper surface of the lower template 12 and is located outside the main body 33. The positioning block 14 covers the extension 35, and the positioning groove 15 is formed on the upper template 11. The positioning block 14 covers the extension 35 and can limit and fix the guide float pin 3 in the vertical direction. The extension 35 reduces the possibility of wobbling or displacement of the guide float pin 3 when subjected to external forces such as the pressure of the material to be processed. The positioning block 14 restricts the vertical movement of the guide float pin 3, enhancing its stability and ensuring it maintains a reliable position during the limiting and guiding of the material to be processed. This prevents instability of the guide float pin 3 from affecting the processing accuracy and stability of the material, ensuring that the guide float pin 3 can continuously and stably perform its limiting and guiding functions. Simultaneously, during the mold closing of the upper and lower mold plates 12, the precise cooperation between the positioning block 14 and the positioning groove 15 provides an additional positioning reference for the upper and lower mold plates 12, effectively reducing offset and misalignment during the mold closing process and significantly improving mold closing accuracy.

[0054] Preferably, in this embodiment, the upper template 11 is provided with a receiving groove corresponding to the guide float pin 3. The receiving groove accommodates the guide float pin 3 when the upper and lower templates 12 are closed, which enables the guide float pin 3 to be smoothly embedded into the upper template 11 during the mold closing process, avoiding structural damage or incomplete mold closing and stamping caused by spatial interference.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
