Description

An automated special-purpose flash cutting die Technical Field

[0001] This application relates to the technical field of stamping dies, and in particular to an automated special-purpose flash cutting die. Background Technology

[0002] In the fields of metal cutting and automated metal processing, a type of stamping die is specifically used to remove burrs from the edges of workpieces. During the burr removal process, the upper and lower dies close together, utilizing the shearing action of their cutting edges to remove excess burrs from the periphery of the workpiece, thereby obtaining a dimensionally accurate part. During the stamping process, the removed burrs typically form continuous ring-shaped or frame-shaped scrap. After stamping, due to elastic recovery or the influence of the die structure, the ring-shaped scrap often clings to and remains on the outer peripheral wall of the lower die, forming a "die-clamping" phenomenon.

[0003] In related technologies, to solve the die-fitting problem, common traditional technical means are to manually pry off the waste material from the outside of the lower die using auxiliary tools such as hooks and pliers after each stamping stroke, or to use additional automated devices such as robotic arms, ejection mechanisms, and air blowing devices to peel off and remove the annular waste material.

[0004] For the aforementioned technologies, whether relying on manual operation or additional automated material handling equipment, a separate, additional waste removal process or dedicated mechanism needs to be introduced outside of the main stamping action. This not only disrupts production continuity and reduces efficiency but may also introduce safety risks due to the increased operational steps, while also increasing the complexity and manufacturing cost of the equipment. Summary of the Invention

[0005] In order to improve the problem of waste material backing in automated special-purpose flash cutting dies and improve the continuity of production, this application provides an automated special-purpose flash cutting die.

[0006] The automated special-purpose flash cutting die provided in this application adopts the following technical solution: An automated special-purpose flash cutting die includes an upper die and a lower die for closing the die and completing the punching and cutting of the flash on the workpiece, an upper die base for mounting the upper die, and a lower die base for mounting the lower die. The upper die has a stamping groove that matches the workpiece body. The lower die is provided with a punch that matches the stamping groove and is used for punching. The lower die base is provided with a waste material separation mechanism for handling flash waste. The waste material separation mechanism is circumferentially arranged around the outside of the punch.

[0007] By adopting the above technical solution, a scrap separation mechanism is set on the outer periphery of the punch to achieve in-situ processing of die scrap, transforming scrap removal into a separation action, thus highly integrating the flash scrap with the main stamping process in space and time. When the punching is completed and the annular scrap is tightly held against the outer wall of the punch, the mechanism actively acts on the scrap, cutting it into several segments. The cut scrap, due to the disruption of its structural integrity, experiences reduced holding force and falls off the die. The scrap separation mechanism eliminates the drawback of relying on subsequent independent processes to remove scrap, thereby improving the continuity and cycle efficiency of the production line.

[0008] Furthermore, the waste separation mechanism includes a plurality of separation cutters spaced apart around the punch, each of the separation cutters being vertically arranged and fixedly connected to the lower die, and each separation cutter having a cutting edge on its top side for contacting the flash.

[0009] By adopting the above technical solution, multiple vertically spaced cutting heads are distributed circumferentially, forming multiple cutting points on the annular waste material. This ensures that the waste material is stably cut into multiple small segments, avoiding the waste material remaining in a ring due to incomplete cutting at a single point. The cutting heads are vertically fixed on the lower die, resulting in a stable and rigid structure that can withstand the interaction forces generated during waste cutting, ensuring durability. The cutting edge on the top side allows the cutting head to accurately contact and apply force to the lower surface of the retained flash waste, completing the shearing or tearing action. This integrates the waste material handling mechanism with the die body, eliminating the need for complex drive or transmission systems, resulting in high reliability and easy maintenance.

[0010] Furthermore, when the upper mold and the lower mold are closed, a protective gap is left between the cutting edge and the bottom side of the upper mold to prevent damage to the cutting edge.

[0011] By adopting the above technical solution, a protective gap is left between the cutting edge and the bottom side of the upper die. This gap ensures that the cutting edge of the cutter head will not make rigid contact with the upper die during the die-cutting process, preventing the cutter head itself from being damaged by chipping, wear, or deformation during the stamping action. This ensures the durability and accuracy of the cutter head in cutting scrap. The protective gap ensures that the scrap cutting function only works at specific locations on the scrap, making the stamping function and scrap handling function of the die clearly separated in time and without interference, thus improving the reliability and service life of the entire die system.

[0012] Furthermore, the waste material separation mechanism also includes a receiving plate for receiving burrs and fragments, the receiving plate being installed on the lower mold, and the receiving plate having clearance slots for each of the separation blades to extend out.

[0013] By adopting the above technical solution, the waste fragments cut by the cutting head first fall onto the receiving plate during the detachment process, instead of scattering randomly inside the equipment or working area. This avoids potential jamming, wear, or contamination of the mold's moving parts by small-sized waste materials, maintaining a clean working environment. The clearance groove on the receiving plate provides space for the cutting head without affecting its fixation and function, reflecting the compactness of the structure. As a centralized intermediate collection platform, the receiving plate provides an orderly transition for waste from detachment to final discharge, facilitating automated centralized collection of waste.

[0014] Furthermore, the number of receiving plates is at least two and they are symmetrically arranged on both sides of the lower die. Each receiving plate is inclined downward from the side closer to the punch to the side farther away from the punch. The lower die has a slope surface that matches the inclination angle of the receiving plate. The lower die base is provided with support frames on both sides for supporting and fixing the receiving plates.

[0015] By adopting the above technical solution, the inclined plate surface can form a slide channel facing outwards from the mold. Waste fragments falling onto the receiving plate can automatically slide and converge towards the outlet of the receiving plate under the influence of their own gravity along the inclined surface, achieving directional movement of the waste. The symmetrical arrangement ensures that waste falling from all directions around the punch can be effectively received and discharged, with no dead zones in collection. The matching inclined surface and support frame on the lower mold ensure the stability and angle accuracy of the receiving plate installation.

[0016] Furthermore, it also includes a feeding auxiliary mechanism for guiding the scrap pieces on the receiving tray to fall.

[0017] By adopting the above technical solution and setting up an independent unloading auxiliary mechanism, proactive assurance is provided for waste discharge, solving the problem of waste potentially stagnating on the receiving tray due to oil adhesion, slight deformation, or electrostatic adsorption. By applying external force such as vibration or air blowing, the frictional resistance or adsorption force between waste fragments and the surface of the receiving tray is overcome, ensuring that even waste with unsatisfactory surface conditions can be removed from the receiving tray surface. This improves the adaptability of waste handling under actual production conditions, avoids blockages or situations requiring manual cleaning due to waste retention, and ensures the continuous smooth operation of the automated process.

[0018] Furthermore, the material feeding auxiliary mechanism is a vibration feeding mechanism, which is located on both sides of the lower mold base. The vibration feeding mechanism includes a linear vibrating motor and a motor mounting bracket. The motor mounting bracket is fixedly connected to the side of the support frame away from the receiving plate, and the linear vibrating motor is installed on the lower side of the motor mounting bracket.

[0019] By adopting the above technical solution, specifically using vibration feeding as a feeding aid, a highly efficient and easily controllable implementation method is provided. A linear vibrating motor generates directional high-frequency micro-amplitude vibrations, which are transmitted to the receiving plate through the motor mounting bracket and support frame. The vibration causes the scrap fragments on the plate surface to jump or creep, breaking the static friction state and promoting the downward sliding of the scrap fragments along the inclined plate surface. The vibration mechanism is installed on the outside of the support frame, achieving relative isolation between the vibration source and the mold body, reducing vibration interference to the precision stamping mold body, and facilitating installation and maintenance.

[0020] Furthermore, the lower mold base is provided with a first conveyor belt below, which cooperates with the feeding auxiliary mechanism and is used to transport the flash fragments. The first conveyor belt is vertically aligned with the outlet position of the receiving tray. The lower mold base is provided with an upper fixed seat for mounting the lower mold base and a lower fixed seat for mounting the first conveyor belt. The upper fixed seat is fixedly connected to the lower fixed seat. The upper fixed seat has a conveying gap at the middle position for the first conveyor belt to pass through along its length.

[0021] By adopting the above technical solution, waste fragments sliding off the receiving tray fall directly onto the continuously operating first conveyor belt and are carried away from the area directly below the mold. This prevents waste from accumulating at the bottom of the equipment, creating conditions for continuous production. A conveying gap is opened in the middle of the upper fixed seat to ensure that the conveyor belt can pass through and receive the waste, maintaining the integrity and support strength of the mold mounting base, i.e., the upper fixed seat. The upper and lower fixed seats are set separately, realizing the functional division and structural integration of the mold installation area and the waste conveying area. The equipment layout is reasonable and facilitates independent maintenance and adjustment of each part.

[0022] Furthermore, a second conveyor belt perpendicular to the conveying direction of the first conveyor belt is provided at an adjacent position of the lower fixed seat, and the second conveyor belt is arranged at the end of the first conveyor belt.

[0023] By adopting the above technical solution, for production lines with multiple sets of automated special flash cutting dies arranged at intervals, waste materials from multiple first conveyor belts can be collected onto a shared second conveyor belt, realizing centralized and directional transfer of waste materials within the workshop. This facilitates the unified transportation of waste materials to designated centralized processing points, such as waste bins, crushers, or balers, reducing the need for manual material handling.

[0024] Furthermore, the material feeding auxiliary mechanism is a purging feeding mechanism, which includes an air outlet pipe and an air source device. The air outlet pipe is arranged on the receiving plate and the air outlet of the air outlet pipe faces the feeding direction of the receiving plate.

[0025] By adopting the above technical solution, the blowing and unloading mechanism provides a non-contact cleaning method. It utilizes compressed air to generate a directional airflow that acts on the flash and debris adhering to the surface of the inclined receiving plate. The airflow overcomes the resistance caused by oil adhesion, slight deformation, or electrostatic adsorption of the debris, blowing it away and accelerating it towards the unloading direction. The blowing action is precise and controllable, suitable for stamping scenarios that are sensitive to vibration or require high positioning accuracy. Airflow blowing keeps the mold area relatively dry, helps to remove some oil stains, and its structure is achieved through pipeline arrangement, without adding complex moving parts, resulting in high reliability and easy maintenance.

[0026] In summary, this application includes at least one of the following beneficial technical effects: By integrating a scrap separation mechanism around the outer periphery of the lower die punch, this mechanism can directly act on the annular flash scrap fitted on the punch after the stamping action, cutting it in situ into multiple fragments. This cutting operation disrupts the overall structure of the scrap, weakening its clamping force, thus allowing it to automatically detach from the die. This integrates the stamping and independent scrap removal processes into a continuous automated process, eliminating production stoppages caused by manual removal or robotic arm handling, improving production cycle time and continuity, and increasing production efficiency. Furthermore, this application constructs a complete post-processing system for scrap by setting an inclined receiving plate and a scrap auxiliary mechanism (vibration or blowing). The receiving plate catches the scrap fragments falling from the die, preventing splashing and contamination of precision die components and the working environment. The inclined design utilizes gravity to achieve initial collection and directional sliding of waste materials. The auxiliary feeding mechanism (such as directional vibration generated by a linear vibrating motor or directional blowing with compressed air) actively overcomes the retention of waste materials caused by oil stains and adsorption forces, ensuring timely removal of waste materials from the mold area, preventing blockages, and ensuring the adaptability of the waste handling process, thus providing a guarantee for continuous and stable production. This application extends waste handling from the mold end to workshop-level collection via a first and second conveyor belt. After sliding from the receiving tray, the waste materials are transported away from the workstation by the first conveyor belt and then centrally transferred via the vertically arranged second conveyor belt. This achieves an automated logistics closed loop from single-point discharge to centralized collection, reducing reliance on manual handling and lowering labor costs. The separate upper and lower fixed seats, through a modular layout, clearly define the functional areas of the equipment and facilitate maintenance. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with Figures 1-9, Embodiment 1, and Embodiment 2. Embodiments

[0038] This application discloses an automated special-purpose flash cutting die. Referring to Figures 1 and 2, the automated special-purpose flash cutting die includes an upper die 1, a lower die 2, an upper die base 3, a lower die base 4, a waste material separation mechanism 5, and a material feeding auxiliary mechanism 6. The upper die 1 and the lower die 2 are used to close the die and complete the flash punching and removal of the workpiece. The upper die base 3 is used to install the upper die 1, and the lower die base 4 is used to install the lower die 2.

[0039] Referring to Figures 3 and 4, the upper die 1 has a stamping groove 11 that matches the workpiece body, and the lower die 2 is provided with a punch 21 that matches the stamping groove 11 and is used for punching. The scrap separation mechanism 5 is provided on the lower die base 4 and is circumferentially arranged around the outside of the punch 21, thereby performing in-situ processing of the die scrap, transforming the removal of scrap into a separation action, and making the flash scrap and the main stamping process highly integrated in space and time.

[0040] Referring to Figure 5, the scrap cutting mechanism 5 includes multiple cutting blades 51 spaced apart around the punch 21 and a receiving plate 52. Each cutting blade 51 is vertically arranged and fixedly connected to the lower die 2, and each cutting blade 51 has a cutting edge 511 on its top side for contacting the flash. When the upper die 1 and the lower die 2 are closed, a protective gap is left between the cutting edge 511 and the bottom side of the upper die 1 to prevent damage to the cutting edge 511. At this time, the cutting blade 51 and the bottom side of the upper die 1 clamp the flash scrap and apply extrusion pressure, and the cutting blade 51 cuts the flash scrap through the cutting edge 511. The multiple spaced vertical cutting blades 51 are distributed circumferentially, forming multiple cutting points on the annular scrap, ensuring that the scrap is stably cut into multiple small segments, and avoiding the scrap remaining in a ring due to incomplete cutting at a single point. If the flash scrap is not completely cut by the cutting edge 511, resulting in unsuccessful separation, the flash scrap generated in the next punching can work together with the separation cutter head 51 to separate the previous flash scrap.

[0041] A protective gap is left between the cutting edge 511 and the bottom side of the upper die 1. This gap is a protective measure for the cutting edge 511. The gap ensures that the cutting edge 511 of the cutter head 51 will not make rigid contact with the upper die 1 during the die-cutting process. This prevents the cutter head 51 from being damaged by chipping, wear, or deformation during the stamping action, and ensures the durability and accuracy of the cutter head 51 for cutting waste.

[0042] Two receiving plates 52 are symmetrically arranged on both sides of the lower die 2. Each receiving plate 52 is inclined downwards from the side closer to the punch 21 to the side farther away from the punch 21. Each receiving plate 52 has a clearance groove 521 for the extension of each cutting head 51. The lower die 2 has a ramp surface 22 that matches the inclination angle of the receiving plates 52. The lower die base 4 has support frames 53 on both sides for supporting and fixing the receiving plates 52. The inclined plate surface forms a slide towards the outside of the die. Waste fragments falling onto the receiving plates 52 can automatically slide and converge towards the outlet of the receiving plates 52 under the influence of their own gravity along the ramp surface, achieving directional movement of the waste.

[0043] Referring to Figures 6 and 7, the material feeding auxiliary mechanism 6 is used to guide the scrap pieces on the receiving plate 52 to fall. In this embodiment, the material feeding auxiliary mechanism 6 is a vibration feeding mechanism 61, which is located on both sides of the lower die base 4. The vibration feeding mechanism 61 includes a linear vibrating motor 611 and a motor mounting bracket 612. The motor mounting bracket 612 is fixedly connected to the side of the support frame 53 away from the receiving plate 52, and the linear vibrating motor 611 is mounted on the lower side of the motor mounting bracket 612. The linear vibrating motor 611 generates directional high-frequency micro-amplitude vibration, which is transmitted to the receiving plate 52 through the motor mounting bracket 612 and the support frame 53. The vibration can cause the scrap pieces on the plate surface to jump or creep, breaking the static friction state and promoting the scrap pieces to slide downward along the inclined plate surface. The vibration mechanism is installed on the outside of the support frame 53 to achieve relative isolation between the vibration source and the die body, reducing vibration interference to the precision stamping die body, and facilitating installation and maintenance.

[0044] The die base has a first conveyor belt 7 below it, which cooperates with the unloading auxiliary mechanism 6 and is used to transport the flash fragments. The first conveyor belt 7 is vertically aligned with the outlet position of the receiving tray 52. ​​Below the lower die base 4, there is an upper fixed seat 71 for mounting the lower die base 4 and a lower fixed seat 72 for mounting the first conveyor belt 7. The upper fixed seat 71 is fixedly connected to the lower fixed seat 72, and the upper fixed seat 71 has a conveying gap 711 at the middle position for the first conveyor belt 7 to pass through along its length. Referring to Figure 1, multiple sets of automated flash cutting dies can be arranged at intervals; in this embodiment, two sets are used as an example. A second conveyor belt 8 is provided at the adjacent position of the lower fixed seat 72, perpendicular to the conveying direction of the first conveyor belt 7, and the second conveyor belt 8 is arranged at the end of the first conveyor belt 7.

[0045] Waste fragments sliding off the receiving tray 52 fall directly onto the continuously operating first conveyor belt 7, being carried away from the area directly below the mold, preventing waste from accumulating at the bottom of the equipment. For production lines with multiple sets of automated dedicated flash cutting molds arranged at intervals, waste from multiple first conveyor belts 7 can be collected onto a shared second conveyor belt 8, achieving centralized and directional transfer of waste within the workshop, facilitating the unified transportation of waste to a designated centralized processing point.

[0046] The implementation principle of an automated special-purpose flash cutting die according to an embodiment of this application is as follows: During the stamping process, the upper die 1 and the lower die 2 close together. The flash of the workpiece is removed by the cooperation of the punch 21 and the stamping groove 11. The resulting annular waste material is elastically contracted and held tightly around the outer periphery of the punch 21. When the die closes, the top cutting edges 511 of multiple cutting heads 51 fixed to the lower die 2 work together with the bottom side of the upper die 1 to clamp the waste material on it and apply extrusion pressure, and use the cutting edges 511 to divide it. Multiple cutting heads form distributed cutting points to ensure that the waste material is stably cut into several small segments. Even if the single cut is incomplete, the new waste material generated by subsequent stamping will work together with the previous waste material to promote its final separation.

[0047] After the waste material is cut, it loses its overall clamping force and falls naturally under the action of gravity, falling into the inclined receiving plates 52 symmetrically arranged on both sides of the mold. In order to overcome the retention of fragments caused by oil stains and other factors, the direct vibration motor 611 installed on the support frame 53 generates directional vibration and transmits it to the receiving plate 52 to assist the waste material to slide out continuously.

[0048] The falling waste fragments fall onto the first conveyor belt 7 and are immediately carried away from the workstation to prevent accumulation. In a multi-mold parallel production line, the waste from the end of the first conveyor belt 7 at each workstation is uniformly collected into the perpendicular second conveyor belt 8, achieving centralized transfer at the workshop level. The entire process of waste generation, separation, detachment, guidance, transport, and collection is completed automatically, achieving efficient, continuous, and clean production. Example

[0049] The difference between the technical solution provided in this embodiment and the technical solution in Embodiment 1 is that the material feeding auxiliary mechanism 6 in this embodiment is a blowing material feeding mechanism 62. Referring to Figures 8 and 9, the blowing material feeding mechanism 62 includes an air outlet pipe 621 and an air source device (not shown). The air outlet pipe 621 is arranged on the receiving plate 52, and the air outlet 622 of the air outlet pipe 621 faces the material feeding direction of the receiving plate 52. The blowing material feeding mechanism 62 provides a non-contact cleaning method, using compressed air to generate a directional airflow that acts on the burrs and debris stuck on the surface of the inclined receiving plate 52. The airflow can overcome the resistance caused by oil stains, slight deformation, or electrostatic adsorption of the debris, blowing it away and accelerating it towards the material feeding direction.
