Description

Technical Field

[0001] This utility model relates to the field of baking pan processing technology, and in particular to a device for separating stamping waste. Background Technology

[0002] Baking pans are core equipment in the food processing industry, and their production quality directly affects the shaping effect, heating uniformity, and food safety of baked goods. Stamping is a key process in the production of baking pans. In the stamping production of baking pans, metal sheets are cut and shaped using molds to form the pan body, flanges, and positioning structures. This process inevitably generates a large amount of stamping waste that matches the pan's contour, such as leftover material around the pan body and waste blocks corresponding to the hollowed-out structures.

[0003] Currently, the waste separation process in the stamping of baking pans generally suffers from low efficiency and insufficient automation. In traditional processing methods, some small-scale manufacturers still rely on manual labor to separate waste from the baking pan workpieces. Operators must manually peel off the waste after the stamping process, which is not only labor-intensive and time-consuming, but also prone to defects such as deformation and surface scratches in the baking pan workpieces due to the uncertainty of manual operation, seriously affecting the product qualification rate. Even if some companies have adopted simple mechanized separation equipment, it often suffers from drawbacks such as simple structure and poor adaptability.

[0004] Baking pans come in a wide variety of sizes, from small square pans for home use to large rectangular pans for industrial production. Their dimensions, shapes, and perforated structures vary significantly. Existing equipment often uses fixed stamping components and positioning mechanisms, making it impossible to quickly adjust them to suit the processing needs of different pan sizes. Changing molds and debugging equipment frequently consumes considerable time, greatly reducing production continuity. Furthermore, traditional equipment lacks precision in waste separation, easily resulting in waste residue or workpiece displacement during the separation process. This not only requires subsequent secondary cleaning but may also cause wear and tear on the stamping dies, increasing equipment maintenance costs.

[0005] Therefore, it is necessary to design a device for separating stamping waste to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for separating stamping waste. This invention features automation, high precision, and multi-specification compatibility, thereby solving problems such as high labor intensity, low production efficiency, insufficient product qualification rate, and poor equipment adaptability in existing technologies. By optimizing the adjustment performance of stamping components and the stability of positioning mechanisms, it achieves efficient separation of stamping waste from baking trays, improving the automation level and economic benefits of the overall production process.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A device for separating stamping waste includes a workbench with a placement platform at its upper end; a fixed frame fixedly connected to the workbench, on which a stamping assembly is mounted, the stamping assembly including multiple fourth cylinders, the telescopic ends of the multiple fourth cylinders being fixedly connected to a horizontal plate, and multiple pressure rods mounted on the horizontal plate; a moving assembly including two third slide rails symmetrically mounted on the upper end of the fixed frame, two moving seats slidably connected to the two third slide rails, a mounting plate fixedly connected to the fixed frame, two first bearing seats mounted on the upper end of the mounting plate, a first lead screw mounted on the two bearing seats, the two moving seats threadedly connected to the first lead screw, each of the two moving seats having a rectangular opening, the multiple fourth cylinders passing through the corresponding rectangular openings, and a first motor mounted on the lower end of the mounting plate, the output shaft of the first motor being connected to the first lead screw via a transmission assembly.

[0008] Preferably, the system further includes an adjustment assembly, which includes a top cover fixedly connected to the upper end of the fixed frame. Two crossbeam rails are slidably connected inside the top cover. Multiple fourth cylinders are slidably connected to the corresponding crossbeam rails. A support frame is fixedly connected to the upper end of the fixed frame. Two second bearing seats and a second motor are mounted on the support frame. A second lead screw is mounted on both second bearing seats. The second lead screw is fixedly connected to the output shaft of the second motor. Two moving blocks are threadedly connected to the second lead screw. The two moving blocks are fixedly connected to the corresponding crossbeam rails.

[0009] Preferably, both the first lead screw and the second lead screw are bidirectional threaded rods.

[0010] Preferably, the upper end of the workbench is fixedly connected to two column plates, and each of the two column plates is fixedly connected to a first slide rail. The placement platform is slidably connected to the two first slide rails. Two first cylinders are symmetrically fixedly connected to the workbench. The lower end of the placement platform is fixedly connected to two connecting blocks, and the telescopic ends of the two first cylinders are fixedly connected to the corresponding connecting blocks.

[0011] Preferably, the upper end of the placement platform is provided with two strip grooves, the worktable is provided with a blocking assembly, the blocking assembly includes two uprights, both of which are L-shaped, and the lower end of the horizontal part of each of the two uprights is fixedly connected with a cylindrical block that mates with the strip grooves, and the worktable is provided with a material discharge port.

[0012] Preferably, the assembly further includes two clamping components. Each clamping component includes a fixed base mounted on a workbench, a second cylinder mounted on the fixed base, a second slide rail fixedly connected to the fixed base, a mounting base fixedly connected to the second slide rail, a telescopic end of the second cylinder fixedly connected to the mounting base, a third cylinder vertically fixedly connected to the mounting base, and a positioning block fixedly connected to the telescopic end of the third cylinder. The positioning block is L-shaped and its horizontal portion is fixedly connected to the telescopic end of the third cylinder.

[0013] Compared with existing technologies, the advantages of this device are: Compared with existing technologies, this device features bidirectional adjustment, balancing multi-specification adaptability and operational convenience, making it more practical. The first lead screw in the device is a bidirectional threaded rod, driven by the first motor to move the moving seat synchronously to both sides along the third slide rail. This allows the entire stamping assembly to be moved to both sides of the worktable after stamping, freeing up ample space for the subsequent robotic arm to pick up material, avoiding equipment interference, and improving the efficiency of automated production line connections. The second lead screw is also a bidirectional threaded rod, its core function being to adjust the spacing between the fourth cylinders on the same side crossbeam rail. By precisely changing the distribution density of the pressure rods, it adapts to baking trays of different sizes and hollow structures, allowing for specification switching without changing the mold, significantly shortening equipment debugging time and improving production continuity. Compared with existing technologies, this device boasts a high degree of automation and precise separation, effectively reducing human intervention and operational defects. Through the coordinated control of multiple sets of cylinders, the pressure rods are stamped and separated, and the positioning blocks are clamped and fixed. Combined with the sliding design of the placement table's rails, this forms an automated process of "positioning-clamping-stamping-separation," avoiding workpiece scratches and deformation caused by manual operation. Simultaneously, the precise mechanical transmission structure reduces waste residue, lowering secondary cleaning costs and the risk of mold wear. Compared with existing technologies, by setting up the blocking component and the strip groove, after each time the waste is punched down and the product is taken away, the operation of the first cylinder will cause the placement platform to move the waste forward. Under the action of the blocking component, the waste is pushed off the placement platform and then falls from the discharge port for collection. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-5 A device for separating stamping waste includes a workbench 1, with a placement platform 6 at the upper end of the workbench 1. A fixed frame 20 is fixedly connected to the workbench 1. A stamping assembly is installed on the fixed frame 20. The stamping assembly includes multiple fourth cylinders 8. The telescopic ends of the multiple fourth cylinders 8 are fixedly connected to a horizontal plate 9. Multiple pressure rods 10 are installed on the horizontal plate 9. The movable assembly includes two third slide rails 21 symmetrically mounted on the upper end of the fixed frame 20. Each third slide rail 21 is a ball linear slide rail, its body fixed to the fixed frame 20 by countersunk screws. The slider is rigidly connected to the movable seat 22, providing low-friction and high-precision sliding performance. Two movable seats 22 are slidably connected to the two third slide rails 21. Each movable seat 22 contains a nut sleeve that matches the first lead screw 23. The nut sleeve is made of self-lubricating material to reduce wear on the lead screw transmission and extend its service life. A mounting plate is fixedly connected to the fixed frame 20, and two first bearing seats are mounted on the upper end of the mounting plate. The first lead screw 23 is mounted on both bearing seats. 3. Two movable seats 22 are threadedly connected to the first lead screw 23. Each of the two movable seats 22 is provided with a rectangular opening 24. Multiple fourth cylinders 8 pass through the corresponding rectangular opening 24. The length of the rectangular opening 24 is greater than the sum of the lengths of the two fourth cylinders 8, so that the distance between the two fourth cylinders 8 can be adjusted. At the same time, the width of the rectangular opening 24 is the same as the width of the fourth cylinder 8, so that the movement of the movable seat 22 drives the fourth cylinder 8 to move. The lower end of the mounting plate is equipped with a first motor 11. The output shaft of the first motor 11 is connected to the first lead screw 23 through a transmission assembly 12. The transmission assembly 12 adopts a synchronous belt pulley transmission structure, including a driving pulley, a driven pulley and a synchronous belt.

[0018] The system also includes an adjustment assembly, which consists of a top cover fixedly connected to the upper end of the fixed frame 20. Two crossbeam rails 25 are slidably connected inside the top cover, and multiple fourth cylinders 8 are slidably connected to the corresponding crossbeam rails 25. A support frame is fixedly connected to the upper end of the fixed frame 20, and two second bearing seats and a second motor 26 are mounted on the support frame. Both the first motor 11 and the second motor 26 are servo motors. A second lead screw 27 is mounted on both second bearing seats. The second lead screw 27 is fixedly connected to the output shaft of the second motor 26. Two moving blocks 28 are threadedly connected to the second lead screw 27. The two moving blocks 28 are fixedly connected to the corresponding crossbeam rails 25. Both the first lead screw 23 and the second lead screw 27 are bidirectional threaded rods. The two ends of the bidirectional threaded rods have opposite thread directions, which can realize the synchronous reverse movement of the two moving parts.

[0019] The upper end of the workbench 1 is fixedly connected to two column plates 13, and each column plate 13 is fixedly connected to a first slide rail 5. The placement platform 6 is slidably connected to the two first slide rails 5. Two first cylinders 4 are symmetrically fixedly connected to the workbench 1. The lower end of the placement platform 6 is fixedly connected to two connecting blocks 14, and the telescopic ends of the two first cylinders 4 are fixedly connected to the corresponding connecting blocks 14.

[0020] The upper end of the placement platform 6 is provided with two strip grooves 7. The strip grooves 7 are opened along the width direction of the placement platform 6. The width of the grooves matches the diameter of the cylindrical block 3. The depth of the grooves is 1 / 3 of the thickness of the placement platform 6, which ensures the positioning effect without affecting the structural strength of the placement platform 6. The worktable 1 is provided with a blocking component, which includes two uprights 2. Both uprights 2 are L-shaped. The lower end of the horizontal part of both uprights 2 is fixedly connected to a cylindrical block 3 that cooperates with the strip grooves 7. The worktable 1 is provided with a material discharge port.

[0021] The system also includes two clamping assemblies. Each clamping assembly includes a fixed base 15 mounted on the workbench 1. A second cylinder is mounted on the fixed base 15. A second slide rail 16 is fixedly connected to the fixed base 15. A mounting base 17 is fixedly connected to the second slide rail 16. The telescopic end of the second cylinder is fixedly connected to the mounting base 17. A third cylinder 18 is vertically fixedly connected to the mounting base 17. A positioning block 19 is fixedly connected to the telescopic end of the third cylinder 18. The positioning block 19 is L-shaped and its horizontal part is fixedly connected to the telescopic end of the third cylinder 18. A rubber anti-slip pad is pasted on the lower end of the horizontal part of the positioning block 19, which can enhance the friction during clamping and avoid causing indentations on the surface of the board.

[0022] The functional principle of this utility model can be explained through the following operation: First, the equipment is debugged and its specifications are adapted. According to the size, shape, and hollow structure characteristics of the baking tray to be processed, the stamping components are precisely adjusted. The second motor 26 is started, and its output shaft drives the bidirectional second lead screw 27 to rotate. Since the second lead screw 27 is threadedly connected to the moving block 28, and the moving block 28 is fixed to the crossbeam rail 25, the two moving blocks 28 will move synchronously inward or outward along the second lead screw 27, thereby driving the crossbeam rail 25 to slide inside the top cover. The adjustment of the crossbeam rail 25 will drive the fourth cylinder 8 slidably connected to it to move synchronously. Adjusting the distance between the two fourth cylinders 8 on the same side, that is, the distance between the horizontal plates 9 on the same side, ensures that the pressure rod 10 can accurately correspond to the waste area of ​​the baking tray.

[0023] After debugging, the workpiece loading and positioning stage begins. The metal sheet to be stamped is placed on the upper end of the placement table 6 using a robotic arm. After placement, the second cylinder of the clamping assembly is activated, pushing the mounting base 17 to move along the second slide rail 16 to above the edge of the sheet. Then, the third cylinder 18 is activated, and its telescopic end drives the L-shaped positioning block 19 downward, so that the horizontal part of the positioning block 19 presses against the surface of the sheet, achieving a stable fixation of the sheet and preventing displacement during the stamping process. After confirming that the sheet metal is securely fixed, the stamping separation and preliminary waste processing stage begins. First, the first motor 11 is controlled to operate. The operation of the first motor 11 causes the two moving seats 22 to move multiple stamping components to the center and then to the designated position. Then, the fourth cylinder 8 is activated, and the telescopic ends of multiple fourth cylinders 8 move down synchronously, causing the horizontal plate 9 and the pressure rod 10 to move towards the surface of the sheet metal. The impact force of the pressure rod 10 separates the baking tray workpiece from the waste. After stamping is completed, the fourth cylinder 8 drives the pressure rod 10 to reset, and at the same time, the first motor 11 is activated, causing its output shaft to reverse. This causes the moving seats 22 to slide along the third slide rail 21 to both sides, moving the stamping components to both sides of the worktable 1. This provides a non-interference space for the robotic arm to pick up the material, allowing the robotic arm to smoothly pick up the processed baking tray workpiece and transport it to the next process. After the workpiece is removed, the waste collection stage begins. At this time, the first cylinder 4 is activated, and its telescopic end pushes the placement platform 6 forward along the first slide rail 5. During this process, the cylindrical block 3 of the blocking component is always embedded in the strip groove 7 of the placement platform 6, which blocks the waste on the placement platform 6. As the placement platform 6 continues to move, the waste gradually detaches from the surface of the placement platform 6 under the blocking force of the cylindrical block 3, and finally falls from the preset discharge port of the worktable 1 into the waste collection device below.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
