Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to a welding sheet stamping die. Background Technology

[0002] Currently, existing technology discloses a stamping die for the production of metal welding sheets, relating to the field of welding sheet technology. Addressing the problem that current welding sheet production requires manual handling of materials for stamping, which is dangerous and can easily injure workers, and involves numerous and cumbersome unloading steps after stamping, followed by packaging, resulting in very low efficiency, this invention proposes the following solution: A base is included, with an outer column fixed to its top. An inner column is nested inside the outer column, and a fixing ring is fixed to the outside of the inner column. Multiple springs are fixed to the top of the fixing ring, and an N-shaped top cover is fixed to the top of each spring. A rotating shaft rotatably connects the outer and inner columns, and two triangular wheels are fixed to the outside of the rotating shaft. This invention enables rapid stamping of materials, separates waste from finished products, and automatically unloads and packages the materials, eliminating the need for manual intervention and ensuring worker safety.

[0003] In the manufacturing of electronic components, the assembly of new energy batteries, and the production of various precision instruments, solder sheets (also known as connecting sheets or nickel sheets) are essential basic connecting materials. Currently, the production of these solder sheets mainly adopts mechanical stamping, which processes rolled metal strips into specific shapes and sizes using stamping equipment. To meet the needs of large-scale industrial production, the stability of the stamping equipment and the ease of maintenance are key factors determining production efficiency.

[0004] However, in existing welding sheet stamping equipment, the core stamping die (stamping head) is prone to wear or fatigue damage due to long-term high-frequency reciprocating impact, thus requiring regular replacement or maintenance. Traditionally, the stamping head is directly fixed to the end of the drive rod using simple bolt fastening or multi-point fixing via flanges. This connection method has significant drawbacks: firstly, when the die needs to be replaced, operators must use wrenches and other auxiliary tools to disassemble multiple fasteners, resulting in limited operating space and a cumbersome and time-consuming process, leading to excessive downtime for equipment maintenance and severely impacting the continuity of the production line; secondly, simple threaded connections are prone to loosening due to stress concentration under prolonged high-frequency vibration, causing slight axial or circumferential displacement of the stamping head. This not only reduces the forming accuracy of the welding sheet but, in severe cases, can even damage the stamping table below or cause a surge in scrap rates.

[0005] Furthermore, some existing stamping devices still lack functional integration. Finished welded sheets after stamping often lack effective guiding and collection structures, easily scattering on the workbench or floor, causing material contamination and increasing the labor intensity of subsequent manual sorting. Simultaneously, if the waste strips generated during stamping are not cleaned up promptly and accumulate around the equipment, they can easily get caught in the transmission mechanism, causing malfunctions. This also makes the production environment messy and difficult to meet the requirements of modern workshops for automation and clean production. Therefore, this utility model proposes an automatic welded sheet stamping and collection device to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems in the existing automatic stamping and storage devices for welding sheets, such as the cumbersome and time-consuming process of changing stamping dies, and the fact that simple threaded connections are prone to loosening under long-term high-frequency impact, affecting stamping stability and accuracy, this utility model aims to provide an automatic stamping and storage device for welding sheets with an improved structure that can effectively solve the above-mentioned defects.

[0007] This utility model provides an automatic stamping and storage device for welding sheets, including a worktable, support legs, a stamping mechanism, and a storage mechanism. The support legs are fixedly installed at the bottom of the worktable, the stamping mechanism is fixedly installed at the top of the worktable, and the storage mechanism is fixedly installed at the bottom of the worktable.

[0008] The stamping mechanism includes a stamping box, a rotating shaft, a turntable, a fixed column, a support platform, and a disassembly assembly. The stamping box is fixedly mounted on the top of the worktable, and the rotating shaft is rotatably mounted inside the stamping box. The front end of the rotating shaft extends to the front side of the stamping box and is fixedly connected to the turntable. The fixed column is fixedly mounted eccentrically on the front side of the turntable. The support platform is fixedly mounted on the inner wall of the stamping box to provide guiding support for the disassembly assembly.

[0009] The disassembly assembly includes a stamping column that slides through the support platform. A linkage block is fixedly installed at the top of the stamping column, and a fixed shaft is fixedly connected between the two linkage blocks. The outer wall of the fixed column slides against the outer wall of the fixed shaft. The rotation of the shaft drives the turntable to rotate, which in turn drives the fixed column to perform circular motion. The fixed column drives the stamping column to reciprocate vertically inside the support platform through the fixed shaft, realizing the conversion from rotational motion to linear stamping motion.

[0010] Preferably, the disassembly assembly further includes a threaded rod, a retaining ring, a retaining block, a grooved post, and a stamping head. The threaded rod is fixedly connected to the center of the bottom end of the stamping post, the retaining ring is fixedly connected to the bottom end of the stamping post and located around the threaded rod, and the retaining block is fixedly connected to the inner wall of the retaining ring. The stamping head is fixedly installed at the bottom of the grooved post.

[0011] Preferably, the top of the grooved post has an internal thread that matches the external thread of the threaded rod, and the outer wall of the grooved post has a locking groove that matches the shape of the locking block. During installation, by rotating the grooved post, the locking block is tightened into the locking groove while the thread is tightened, achieving a dual locking of axial thread fastening and circumferential snap-locking between the stamping head and the stamping post, ensuring connection reliability during high-speed stamping.

[0012] Preferably, the stamping mechanism further includes a stamping table, which is fixedly installed on the top of the workbench and located directly below the stamping head, for use in conjunction with the stamping head to complete the stamping and shearing operations. A guide ramp is provided on one side of the stamping table, extending to a through hole inside the workbench, for automatically guiding the stamped finished welding sheet to the receiving mechanism below.

[0013] Preferably, the storage mechanism includes a fixed box and a storage container. The fixed box is fixedly installed at the bottom of the workbench and connected to the material feeding channel of the stamping mechanism. The storage container is slidably installed inside the fixed box to collect the fallen finished welding pieces. For easy observation and removal, the front end of the storage container is provided with a transparent observation window and a pull ring.

[0014] Preferably, the receiving mechanism further includes fixing blocks and a flattening shaft. Two fixing blocks are fixedly installed at intervals on the top of the worktable and located on the feeding side of the stamping mechanism, and the flattening shaft is rotatably installed between the two fixing blocks on opposite sides. The welding coil raw material to be stamped passes through the gap between the flattening shaft and the worktable surface. The rolling action of the flattening shaft eliminates the curling stress of the material, ensuring the flatness of the feed.

[0015] Preferably, the receiving mechanism further includes connecting blocks, a linkage table, guide shafts, and a winding shaft. Two connecting blocks are fixedly installed at intervals on the top of the worktable and located on the discharge side of the stamping mechanism. The linkage table is fixedly mounted on the top of the two connecting blocks to support the waste material handling assembly. Two guide shafts are rotatably installed on both sides of the top of the linkage table, and the winding shaft is rotatably installed between the two guide shafts for automatically winding and collecting the continuous waste strip generated after the stamping operation.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting up a disassembly assembly consisting of a threaded rod, a locking ring, a locking block, and a grooved post, uses a threaded connection to achieve axial fastening, and cooperates with the locking block to embed into the locking groove to achieve circumferential limiting. This solves the problems of cumbersome and time-consuming stamping die replacement process and easy loosening and falling off of simple threaded connections during stamping vibration in the prior art. It achieves the technical effect of quickly completing the disassembly and replacement of the stamping head without the need for complex auxiliary tools, and significantly improves the connection stability and safety of the die during operation through the double locking structure.

[0017] 2. This utility model solves the problems of difficulty in collecting scattered stamped finished products and difficulty in intuitively judging the collection amount in the prior art by setting a storage mechanism at the bottom of the workbench and using a fixed box connected to the stamping discharge port and a storage box slidably installed inside it. It achieves the technical effect of automatic material collection of finished welding pieces under the action of gravity, and the accumulation can be monitored in real time through a transparent observation window. The drawer-type design of the storage box facilitates the operator to quickly clean and transfer finished products.

[0018] 3. This utility model solves the problems in the prior art where internal stress in rolled raw materials affects stamping accuracy and waste strips accumulate randomly after stamping, polluting the working environment, by setting a flattening shaft on the feeding side and a winding shaft on the discharging side of the stamping mechanism. It achieves the technical effect of automatically flattening the welded coil before stamping to ensure processing quality, and automatically winding and recycling the waste strip neatly after stamping, keeping the worktable clean and orderly, and reducing manual cleaning costs.

[0025] Example: Please refer to Figures 1 to 4 This utility model provides a welding sheet stamping die, which aims to solve the problems of cumbersome die replacement, low efficiency of waste and finished product collection, and difficulty in ensuring stamping stability in the prior art welding sheet production equipment.

[0026] A welding sheet stamping die includes a workbench 1 and a support leg 2 fixedly installed at the bottom of the workbench 1. The support leg 2 provides stable support for the whole device. The workbench 1 serves as the mounting carrier for the core component. A stamping mechanism 3 is fixedly installed on its top and a storage mechanism 4 is fixedly installed on its bottom. The stamping mechanism 3 is used to perform automated stamping and forming operations on the raw materials conveyed to the surface of the workbench 1. The storage mechanism 4 is used to collect the finished products after stamping and to wind up the generated waste materials.

[0027] The stamping mechanism 3 includes a stamping box 31 fixedly installed on the top of the workbench 1. A rotating shaft 32 is rotatably installed inside the stamping box 31. The rotating shaft 32 is used to receive the rotational power input from an external power source. The front end of the rotating shaft 32 extends to the front side of the stamping box 31 and is fixedly connected to a turntable 33. A fixed column 34 is fixedly installed at an eccentric position on the front side of the turntable 33. The fixed column 34 rotates in a circular motion with the rotation of the turntable 33. A support platform 35 is fixedly installed on the inner wall of the stamping box 31. The support platform 35 is used to provide vertical guide support.

[0028] The disassembly assembly 36 includes a stamping column 361 that slides through the support platform 35. The stamping column 361 can only move vertically under the restriction of the support platform 35. Two linkage blocks 37 are fixedly installed at the top of the stamping column 361. A fixed shaft 38 is fixedly connected between the opposite sides of the two linkage blocks 37. The fixed column 34 is located between the two linkage blocks 37, and the outer wall of the fixed column 34 slides against the outer wall of the fixed shaft 38. When the rotating shaft 32 rotates and drives the turntable 33 to rotate, the fixed column 34 located in the eccentric position makes a circular motion. During the movement, the fixed column 34 continuously squeezes or lifts the fixed shaft 38, thereby driving the stamping column 361 to reciprocate vertically inside the support platform 35 through the fixed shaft 38, realizing the mechanical transmission process of converting rotational motion into linear stamping motion.

[0029] The stamping mechanism 3 also includes a uniquely designed disassembly assembly 36, and the disassembly assembly 36 forms a specific structural fit and connection with the aforementioned support platform 35 and stamping platform 39. Please refer to [the relevant documentation / reference]. Figure 2 and Figure 4 The core structure will now be explained in detail.

[0030] The disassembly assembly 36 has a stamping column 361 as a moving carrier. The stamping column 361 is slidably installed in the internal hole of the support platform 35. The threaded rod 362 is fixedly connected to the center of the bottom end of the stamping column 361 to provide axial connection support force. The locking ring 363 is fixedly connected to the bottom end face of the stamping column 361 and located around the threaded rod 362. The locking ring 363 is used to provide external limiting protection. The locking block 364 is fixedly connected to the inner wall surface of the locking ring 363. The threaded rod 362, the locking ring 363, and the locking block 364 together constitute the male interface for mold installation.

[0031] The mold connecting component that works in conjunction with it is a grooved post 365. The top of the grooved post 365 has an internal thread hole that matches the external thread of the threaded rod 362. The outer wall of the grooved post 365 has an L-shaped engaging groove that matches the shape of the engaging block 364. The stamping head 366 is fixedly installed at the bottom of the grooved post 365. The stamping head 366 is the execution component that directly contacts the welding coil material for stamping and forming. The grooved post 365 is used to realize the quick assembly and disassembly connection between the stamping head 366 and the stamping post 361.

[0032] In the assembled state, by rotating the grooved post 365, the threaded rod 362 is screwed into the internal threaded hole at the top of the grooved post 365, achieving axial fastening through threaded connection. At the same time, the locking block 364 slides into and locks along the trajectory of the L-shaped locking groove. This dual locking structure of threaded fastening and buckle limiting ensures that the grooved post 365 and the stamping head 366 will not axially fall off when subjected to high-frequency vertical impact force, and can effectively prevent circumferential loosening and rotation caused by vibration, ensuring the accuracy and safety of stamping operations. When it is necessary to replace the stamping head 366 of different specifications, simply rotate the grooved post 365 in the opposite direction to quickly unlock and disassemble.

[0033] Meanwhile, the stamping table 39 is fixedly installed on the top surface of the workbench 1 and is precisely located directly below the stamping head 366. The top of the stamping table 39 is provided with a stamping die hole for the stamping head 366 to cut into, which is used to cooperate with the stamping head 366 to complete the shearing and forming of the welding sheet. A downward inclined guide slide is also provided on one side of the stamping table 39. The end of the guide slide extends to the pre-set through hole inside the workbench 1. The structure utilizes the principle of gravity so that the stamped welding sheet can automatically slide down the guide slide into the space below the workbench 1, which prepares the material guide for the subsequent automatic storage process.

[0034] As a preferred embodiment, the storage mechanism 4 is specifically configured as follows: a fixed box 41 is fixedly installed at the corresponding discharge position at the bottom of the workbench 1, and the top opening of the fixed box 41 is connected to the material drop channel inside the workbench 1. The front end of the fixed box 41 has a storage cavity, and the storage box 42 is slidably installed in the storage cavity of the fixed box 41 to receive finished welding pieces sliding down from above. In order to solve the technical problem that it is difficult to observe the internal storage volume of the closed box, a transparent observation window is embedded in the front end of the storage box 42, and a pull ring or handle is fixedly installed below the transparent observation window. The operator can intuitively judge the stacking height of the welding pieces inside the storage box 42 through the transparent observation window. When the storage box 42 is full, the storage box 42 can be smoothly pulled out from the fixed box 41 like a drawer for dumping and cleaning by applying external force through the pull ring.

[0035] In a preferred embodiment, the receiving mechanism 4 is provided with a flattening component on the feeding side of the stamping mechanism 3. The component includes two fixed blocks 43 fixedly installed at intervals on the top of the worktable 1, and a flattening shaft 44 rotatably installed between the inner walls of the two fixed blocks 43 on opposite sides. The flattening shaft 44 spans over the material conveying path. Before entering the stamping box 31, the welding coil material to be processed first passes through the gap between the flattening shaft 44 and the worktable 1, and the rolling action of the flattening shaft 44 physically flattens the passing welding coil.

[0036] In a preferred embodiment, the storage mechanism 4 is provided with a waste material winding assembly on the discharge side of the stamping mechanism 3. The assembly includes two connecting blocks 48 fixedly installed at intervals on the top of the workbench 1, and a linkage table 45 fixedly mounted on the top of the two connecting blocks 48. The linkage table 45 plays a supporting and guiding role. Guide shafts 46 are rotatably installed on both sides of the top of the linkage table 45, and a winding shaft 47 is rotatably installed between the two guide shafts 46. After the stamping is completed, the waste material strip leaves the stamping area, is conveyed through the surface of the linkage table 45 and passes through the guide shafts 46, and the final end is fixed on the winding shaft 47. As the winding shaft 47 rotates under the drive of external power or linkage structure, the waste material strip is continuously and neatly wound on the outer wall of the winding shaft 47, realizing the automatic recycling of waste.

[0037] The implementation principle of this application embodiment is as follows: The device is mainly supported by the support leg 2 fixed at the bottom of the workbench 1. The stamping mechanism 3 fixed at the top of the workbench 1 has a power source that drives the internal components of the stamping mechanism 3 to perform the stamping of the welding sheet. After the welding sheet is stamped, during the transportation of the welding coil, the stamped welding sheet enters the storage mechanism 4 fixed at the bottom of the workbench 1 through the holes on the surface of the workbench 1, thereby collecting the stamped welding sheet.

[0038] During the stamping process of the welding sheet by the stamping mechanism 3 at the top of the workbench 1, the rotating shaft 32 inside the stamping box 31 is driven by the power source to rotate the turntable 33 fixed to the front side of the rotating shaft 32. Then, the special structure at the front end of the fixing column 34 fixed to the front side of the turntable 33 slides on the outer wall of the fixing shaft 38 fixed on the side close to the two linkage blocks 37. Due to the rotation of the fixing column 34, the fixing shaft 38 on the inner wall of the fixing column 34 moves up and down. At the same time, one of the fixing shafts 38 is fixed to the top of the stamping column 361. Then, the fixing shaft 38 moves up and down with the fixing column 34. During the up-and-down movement driven by the component 36, the internal component stamping column 361 of the disassembly assembly 36 moves up and down at the internal hole of the support platform 35 fixed to the inner wall of the stamping box 31. At the same time, the stamping column 361 drives the stamping head 366 fixed to the bottom of the groove column 365 to move up and down, thereby stamping the welding sheet. During the stamping process of the welding sheet, the stamping head 366 continuously contacts the stamping table 39 fixed to the top of the worktable 1 by the positioning column, so that the stamped welding sheet enters the fixed box 41 for collection through the slide on the left side of the stamping table 39 during transportation.

[0039] During the stamping process of welding sheets, if the stamping die breaks or if different types of welding sheets need to be stamped, the stamping head 366 needs to be replaced. First, open the cabinet door at the front of the stamping box 31 to expose the stamping components inside the stamping box 31 to the workers. Then, rotate the grooved post 365 fixed to the top of the stamping head 366, causing the engaging block 364 connected inside the engaging ring 363 fixed to the bottom of the stamping post 361 to gradually disengage from the engaging groove on the outer wall of the grooved post 365. At the same time, the external thread on the inner wall of the grooved post 365 continuously disengages from the internal thread on the outer wall of the threaded rod 362 fixed to the bottom of the stamping post 361. Subsequently... When the locking block 364 is completely disengaged from the outer locking groove of the groove post 365, the stamping head 366 and the groove post 365 are pulled downwards at the bottom of the stamping box 31, thereby completing the disassembly of the stamping head 366. When installing a new stamping head 366, simply rotate the locking block 364 and the outer wall of the groove post 365 to engage. At the same time, rotating the groove post 365 makes it difficult for the locking block 364 to disengage from the groove post 365 by manual external force. The connection between the threaded rod 362 and the groove post 365 is further strengthened, and the stamping head 366 is fixed to the bottom of the stamping post 361 to ensure the stability of the stamping of the welding sheet.

[0040] When the collecting mechanism 4 collects the stamped welding sheets and waste, firstly, the unstamped welding coils are flattened by the flattening shaft 44 fixed on one side of the two fixed blocks 43. Then, the stamped welding coils are collected by the winding shaft 47 fixed between the two guide shafts 46 at the bottom of the linkage table 45. The winding shaft 47 rotates continuously during the stamping process to complete the winding of waste, facilitating subsequent waste collection. The linkage table 45 is fixed between two connecting blocks 48, and the fixed blocks 43, guide shafts 46, and connecting blocks 48 are all fixed to the top of the worktable 1. During the stamping process, the waste welding coil is transported and the stamped welding sheet moves to the left. The welding sheet is subjected to its own weight and enters the fixed box 41 fixed at the bottom through the groove inside the worktable 1. It is collected by the collection box 42 fixed inside the fixed box 41. When a certain amount of welding sheet is collected inside the collection box 42, the situation of the welding sheet collection inside the collection box 42 can be seen through the transparent observation window at the front of the collection box 42. After a certain amount of welding sheet is collected, the collection box 42 can be separated from the fixed box 41 by the pull ring at the front of the collection box 42, which facilitates the subsequent arrangement of the welding sheet.

[0041] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
