[0002] In the field of stamping die manufacturing, heat treatment is a key process for improving die performance. Currently, the following problems commonly exist when sending die blanks into heat treatment equipment for processing: First, most current loading and unloading operations still rely on manual labor or simple hoisting equipment, resulting in high labor intensity, low efficiency, and safety threats to operators due to the high-temperature environment. Second, traditional heat treatment equipment has limited functionality in its loading and heating areas, separating material transfer from the heating process, leading to discontinuous production lines and limited overall production efficiency. Furthermore, during material transfer, it is difficult to ensure the stability of the molds, posing a risk of dropping or impact, and the oxide scale and other debris generated during heat treatment are difficult to collect, affecting equipment cleanliness and workpiece quality. Therefore, there is an urgent need for an integrated device that can automate loading and unloading and efficiently integrate with the heat treatment process to solve these problems.

A unique gear transmission component ensures the supporting mesh plate maintains a stable, upward-facing orientation during the cylinder's rotation, acting like a stable basket. This effectively prevents the mold from tipping over or slipping during transport, ensuring the safety of both the mold and the equipment. It also effectively limits the escape of high-temperature gases from the machine casing, preventing burns to workers and reducing energy consumption of the heating components. Simultaneously, the integrated heating and debris collection design ensures a clean heat treatment environment and workpiece quality. The integration of loading, heating, unloading, and debris collection functions into a single chassis results in a rational layout and high space utilization.

[0014] Example 1 like Figures 1-5As shown, this utility model proposes a heat treatment feeding device for stamping die manufacturing, including a housing 1, a first drive assembly 5, a bearing mesh plate 7, a transmission assembly, and a material gripping mechanism. The housing 1 houses a heating assembly 2 and a guide frame 3 located above the heating assembly 2. The heating assembly 2 employs, but is not limited to, a resistance wire heater and a temperature sensor for monitoring the internal temperature of the housing 1. The guide frame 3 has a through hole 301, and a cylinder 4 is rotatably mounted inside the guide frame 3. A receiving groove 42 adapted to the through hole 301 is provided on the cylinder 4, and a disc 6 is rotatably mounted at each end of the receiving groove 42. A central shaft 41 is coaxially mounted on the cylinder 4, and the central shaft 41 is rotatably connected to both the housing 1 and the guide frame 3. A support platform 12 is provided on the housing 1. The first drive assembly 5 includes, but is not limited to, a servo motor. The body of the servo motor is mounted on the housing 1, and the output end of the servo motor is connected to the central shaft 41 via a coupling. The servo motor drives the cylinder 4 to rotate during operation. The supporting mesh plate 7 is rotatably mounted in the receiving groove 42. Both ends of the supporting mesh plate 7 are connected to corresponding discs 6. A support shaft is coaxially mounted on the disc 6, and the support shaft is rotatably connected to the guide frame 3. A transmission assembly connects the central shaft 41 and the support shaft to ensure that the opening of the supporting mesh plate 7 always faces upwards while the cylinder 4 rotates. The transmission assembly includes a connecting rod 43, a first gear 8, a fixed plate 9, and a second gear 10. A circular groove coaxial with the cylinder 4 is provided, and the connecting rod 43, the first gear 8, and the second gear 10 are all located within the circular groove. The connecting rod 43 is fixedly connected to the central shaft and rotatably connected to the support shaft. The first gear 8 is coaxially connected to the support shaft. The fixed plate 9 is located within the circular groove and rotatably connected to it. The fixed plate 9 is fixedly connected to the guide frame 3. The second gear 10 is coaxially connected to the fixed plate 9, and the central shaft 41 is coaxially rotatably connected to both the fixed plate 9 and the second gear 10. The first gear 8 and the second gear 10 are of the same specifications and mesh. A receiving box 11 is provided on the chassis 1. One end of the receiving box 11 is inserted into the chassis 1 and located below the heating component 2. A handle is provided on the end of the receiving box 11 that extends out of the chassis 1. A limiting component is provided on the receiving box 11 to restrict its relative sliding with respect to the chassis 1. This limiting component includes, but is not limited to, a buckle. A gripping mechanism is provided on the chassis 1. The gripping mechanism includes a bracket 13, a slide 14, a second drive component 15, a movable plate 16, a mechanical gripper 18, and a third drive component 19. The bracket 13 is provided on the chassis 1. The slide 14 is slidably mounted on the bracket 13. The second drive component 15 includes, but is not limited to, a linear module and a slide rail. The linear module and the slide rail are arranged parallel to each other on the bracket 13. One end of the slide 14 is slidably connected to the slide rail, and the other end is connected to the output end of the linear module. In the working state, the linear module drives the slide 14 to slide along the length direction of the bracket 13. The movable plate 16 is located below the slide 14, and the body of the mechanical gripper 18 is connected to the movable plate 16.The third drive assembly 19 includes, but is not limited to, a servo electric cylinder. The body of the servo electric cylinder is mounted on the slide block 14. The output end of the servo electric cylinder is connected to the movable plate 16. A slide rod that slides along its height direction is mounted on the bracket 13. The slide rod is connected to the movable plate 16. When the servo electric cylinder is in operation, the third drive assembly 19 drives the movable plate 16 to slide along the height direction of the bracket 13, so as to grab the mold to be processed on the tray 12 and place it on the carrier mesh plate 7 through the material grabbing mechanism, or grab the mold that has been heat treated on the carrier mesh plate 7 and place it on the tray 12. There are two trays 12 and they are respectively set on both sides of the upper opening of the housing 1.
[0015] It should be noted that this technical solution also includes a control panel, which uses a combination of HMI (Human Machine Interface) and PLC (Programmable Logic Controller). The HMI provides users with an intuitive and user-friendly interface, allowing them to easily issue various commands by touching the screen. Meanwhile, the mechanical gripper uses, but is not limited to, a two-grip robotic arm.
[0016] In this invention, initially, a receiving groove 42 on the cylinder 4 and its internal supporting mesh plate 7 face the opening above the housing 1. At this time, the material handling mechanism begins to operate: the second drive assembly 15 drives the slide 14 to move along the bracket 13 to above the platform 12, and the third drive assembly 19 drives the movable plate 16 and the mechanical claw 18 to descend, with the mechanical claw 18 grasping the mold to be heat-treated placed on the platform 12. Subsequently, the mechanical claw 18 is raised and moved laterally to directly above the opening of the housing 1, then descends again, placing the mold stably on the supporting mesh plate 7 facing the opening. After the material loading is completed, the first drive assembly 5 (servo motor) starts, driving the cylinder 4 and its central shaft 41 to rotate 180 degrees. Due to the function of the transmission assembly—the second gear 10 on the stationary fixed plate 9, which meshes with the first gear 8 coaxially connected to the support shaft, transmits the reverse rotational motion to the support shaft—this transmission process ensures that no matter how the cylinder 4 rotates, the bearing mesh plate 7, fixed to the support shaft, can maintain a stable posture with its opening always facing upwards under the combined action of gravity and transmission, like a stable "basket." After rotating 180 degrees, the bearing mesh plate 7 carrying the mold to be processed is transferred into the sealed cavity formed by the machine housing 1 and the guide frame 3, and is located between the heating components 2 to begin heat treatment. At the same time, another empty bearing mesh plate 7, which has completed unloading, rotates to the opening above the machine housing 1, ready to receive the next mold to be processed. When the heat treatment process is completed, the first drive assembly 5 drives the cylinder 4 to rotate 180 degrees again. The mold that was originally heat-treated inside rotates out with the bearing mesh plate 7 to the opening position, while the new mold to be processed is transferred inside. The material-grabbing mechanism operates again, grabbing the processed mold from the support mesh plate 7 and moving it back to the support table 12 to complete the unloading. During this process, any oxide scale or other debris that may be generated during the heat treatment of the mold will fall through the mesh of the support mesh plate 7 and the through holes 301 on the guide frame 3, eventually collecting in the receiving box 11 located below the heating component 2. The debris can be cleaned periodically by pulling out the receiving box 11 with the handle, and the limiting component ensures its stability during operation.
[0017] Example 2 like Figure 1 and Figure 5 As shown, the present invention proposes a heat treatment feeding device for stamping die manufacturing. Compared with Embodiment 1, the bottom of the movable plate 16 is provided with an electric turntable 7, the body of the mechanical claw 18 is connected to the output end of the electric turntable 7, and the bottom of the slide 14 is provided with a vision probe 20 for detecting the position status of the raw material on the feeding side support 12. The vision probe 20 adopts, but is not limited to, a CCD vision camera, and the vision probe 20 is electrically connected to the PLC controller.
[0018] In an optional embodiment, a vision probe 20 is used to detect the position status information of the mold on the feed side support 12, including angle and position. The status information is fed back to the controller, thereby enabling the linear module and electric turntable 7 to adapt their actions and adjust the mechanical gripper 18 to the appropriate clamping angle and position. This structure can avoid clamping instability caused by inaccurate mold placement.
[0019] Example 3 like Figure 1 and Figure 5 As shown, the present invention proposes a heat treatment feeding device for stamping die manufacturing. Compared with Embodiment 1, the number of movable plates 16 is two. Each movable plate 16 is connected to a set of mechanical claws 18, and two servo electric cylinders are provided on the slide 14. The output ends of the two servo electric cylinders are respectively connected to the movable plates 16 on the corresponding sides. Through the cooperation of the two sets of mechanical claws 18, the device can transfer the heat-treated die from the supporting mesh plate 7 to the discharge side support platform 12 on one side, and grab the die to be processed from the feeding side support platform on the other side and transfer it to the supporting mesh plate 7.
[0020] In an optional embodiment, two sets of mechanical claws 18 can simultaneously pick up materials and place them into the carrier mesh plate 7 and pick up materials from the carrier mesh plate 7 and place them onto the tray 12, thereby improving the efficiency of material transfer.
[0021] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
