Description
Technical Field
[0001] This utility model relates to the field of mold processing technology, specifically a built-in chip removal and scrap removal device for stamping dies. Background Technology
[0002] The built-in chip removal and scrap removal device of the stamping die is a special mechanism that is integrated inside the stamping die. It can simultaneously break up waste materials (such as blanking edges and waste blocks) into small pieces during the stamping process and automatically discharge them from the die. The core is to realize the integration of "chip removal" and stamping action without the need for external independent equipment.
[0003] Currently, most stamping dies with built-in chip removal and scrap removal devices rely solely on suction for chip removal. Some heavier or larger chips are not easily able to fall into the cleaning tube, resulting in poor chip removal efficiency. Furthermore, the diameter and depth of the stamping chip removal hole are usually limited, and irregular shapes and sizes of scrap can easily cause blockages. For example, some long strips or large blocks of scrap may get stuck in the channel, affecting chip removal efficiency and even damaging the stamping material.
[0004] Therefore, a built-in chip removal and scrap removal device for stamping dies is proposed to address the above problems. Utility Model Content

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0025] This application discloses a built-in crushing and chip removal device for stamping dies, including an upper stamping die 1 and a lower stamping die 2. A drive rack 3 is fixedly installed in the middle of the back of the upper stamping die 1. A discharge pipe 4 is fixedly installed in the middle of the lower stamping die 2. A support rod 5 is rotatably installed on one side of the inner cavity of the discharge pipe 4. A driven gear 6 is fixedly installed at the end of the support rod 5. A transmission rod 7 is rotatably installed on the other side of the discharge pipe 4. A first transmission gear 8 is fixedly installed at one end of the transmission rod 7 and meshes with the drive rack 3. A second transmission gear 9 is fixedly installed at the other end of the transmission rod 7 and meshes with the driven gear 6. A crushing component 10 is sleeved on the surface of the support rod 5 and the transmission rod 7 and inside the discharge pipe 4.
[0026] Reference Figure 1 , Figure 2 , Figure 4 Through the structural design of the drive rack 3, support rod 5, driven gear 6, transmission rod 7, first transmission gear 8, second transmission gear 9, and crushing component 10, the function of reusing stamping kinetic energy is realized. Thus, the mechanical force of the stamping die closing and opening can be converted into crushing power to crush waste materials, thereby ensuring the subsequent chip removal efficiency.
[0027] An assembly frame 11 is fixedly installed on the top of the stamping die 2, and slide rails 12 are fixedly installed on the inner walls on both sides of the assembly frame 11.
[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 The assembly frame 11 provides installation support for components such as slide rail 12 and cylinder 13, forming an independent assembly unit. This facilitates the subsequent assembly, debugging, and maintenance of each component, while also protecting the internal structure. The slide rail 12 can cooperate with the T-shaped limit block 16 to guide the movement of the L-shaped support plate 15, ensuring that the L-shaped support plate 15 moves smoothly along a fixed trajectory under the drive of the cylinder 13, avoiding deviation that could affect the positioning accuracy of the core.
[0029] Cylinders 13 are fixedly installed on both sides of the assembly frame 11, and flanges 14 are fixedly installed at the output end of the cylinders 13.
[0030] Reference Figure 3 and Figure 5 The cylinder 13 and flange 14 facilitate the movement of the L-shaped support plate 15 by means of the telescopic movement of the output end, so as to realize the opening and closing and positioning of the split core. At the same time, the synchronous movement of the split cores on both sides facilitates the release of the limit effect on the waste material.
[0031] An L-shaped support plate 15 is fixedly connected to one side of the flange 14 by bolts. T-shaped limit blocks 16 are fixedly installed on both sides of the L-shaped support plate 15. The T-shaped limit blocks 16 are adapted to the cross-section of the slide rail 12.
[0032] Reference Figure 3 and Figure 5 The L-shaped support plate 15 and the T-shaped limiting block 16 facilitate the use of the assembly frame 11 and the slide rail 12 to constrain the core path, thereby ensuring the stability of the core during movement.
[0033] A triangular support frame 17 is fixedly installed on the L-shaped support plate 15 near the middle of the stamping die 2. The top of the triangular support frame 17 is connected to the split core A18 and the split core B19 by bolts.
[0034] Reference Figure 3 and Figure 5 The triangular support frame 17 provides support for the split cores A18 and B19. The triangular structure improves the stability of the support and ensures that the split cores are not easily deformed when subjected to pressure during the stamping process, thus ensuring the forming accuracy of the workpiece. The split cores A18 and B19 can be combined to form the cavity for forming the workpiece, so that the waste can be quickly discharged later.
[0035] A triangular slot 20 is provided on the side of the split core A18 near the split core B19, and a triangular block 21 is fixedly installed on the side of the split core B19 near the split core A18.
[0036] Reference Figure 5 The triangular slot 20 and the triangular block 21 work together to facilitate precise positioning when the split core A18 and the split core B19 are closed, ensuring that the two fit tightly together and avoiding burrs or dimensional deviations in the workpiece due to misalignment.
[0037] A material collection hopper 22 is fixedly installed at the bottom of the discharge pipe 4, and a drawer 23 is movably installed on the front of the material collection hopper 22.
[0038] Reference Figure 4 The drawer 23 facilitates the collection and centralized processing of the crushed waste material, making subsequent centralized processing easier.
[0039] Working principle: When using this device, the output ends of the cylinders 13 on both sides extend and push the L-shaped support plates 15 on both sides to slide in opposite directions inside the assembly frame 11. The L-shaped support plates 15, in conjunction with the triangular support frame 17, drive the split cores A18 and B19 to fit together. After the triangular locking block 21 is embedded in the triangular locking groove 20, the T-shaped limiting block 16 moves inside the slide rail 12 to place the workpiece to be stamped inside the split core. The stamping equipment drives the upper stamping die 1 to move downward, cooperating with the split cores A18 and B19 on the lower stamping die 2 to complete the stamping of the workpiece. During the descent of the upper stamping die 1, the upper stamping die 1... The drive rack 3 on the back moves downward synchronously with the upper stamping die 1. Because the drive rack 3 meshes with the first transmission gear 8, it drives the first transmission gear 8 to rotate, which in turn drives the transmission rod 7 to rotate. The second transmission gear 9 at the other end of the transmission rod 7 rotates synchronously with the transmission rod 7. Because the second transmission gear 9 meshes with the driven gear 6, it drives the driven gear 6 and the support rod 5 connected to it to rotate. The crushing parts 10 on the surface of the support rod 5 and the transmission rod 7 rotate synchronously with both of them. The waste generated by stamping enters the discharge pipe 4 under the action of gravity. The high-speed rotating crushing parts 10 crush the large pieces of waste into small pieces. The crushed waste enters the drawer 23 inside the collection hopper 22 under the guidance of the discharge pipe 4.
[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
