Description

Technical Field

[0001] This application relates to the field of cooling stamped products, and more particularly to a high-speed stamped product cooling system. Background Technology

[0002] High-speed stamping technology is a highly efficient forming process widely used in modern manufacturing. It rapidly processes sheet metal into parts of specific shapes through high-speed, continuous stamping motions, and is widely applied in the automotive, electronics, and home appliance industries. This technology boasts advantages such as high production efficiency, low cost, and good consistency, meeting the demands of large-scale production.

[0003] However, with the continuous increase in stamping speed, the workpiece generates a large amount of heat energy due to plastic deformation and friction during the forming process, leading to a sharp increase in local temperature. This phenomenon not only affects the dimensional accuracy and surface quality of the workpiece, but may also cause changes in the microstructure of the material, such as grain coarsening or residual stress concentration, thereby reducing the mechanical properties and durability of the product. Utility Model Content

[0004] To facilitate heat dissipation from the workpiece, this application provides a high-speed stamping product cooling system.

[0005] The high-speed stamping product cooling system provided in this application adopts the following technical solution: A high-speed stamping product cooling system includes a stamping platform and a mounting block. The upper end of the stamping platform is provided with a mounting groove, and the mounting block is embedded in the mounting groove. The mounting block is provided with a mounting opening for workpieces to pass through. The two ends of the mounting block are respectively provided with a water inlet and a water outlet. The mounting block is provided with a heat dissipation channel, which is located on the outer periphery of the mounting opening. Both the water inlet and the water outlet are connected to the heat dissipation channel.

[0006] By adopting the above technical solution, the mounting block with heat dissipation channels is integrated into the stamping platform, allowing the coolant to flow directly in the closed channels surrounding the workpiece. This achieves precise and efficient cooling of the workpiece's outer periphery during high-speed stamping, effectively removing the instantaneous heat generated during stamping and significantly reducing workpiece deformation, dimensional deviations, and microstructure changes caused by temperature rise. This, in turn, improves the product's processing accuracy, surface quality, and consistency of mechanical properties.

[0007] Preferably, the height of the outlet is greater than the height of the inlet, the two ends of the heat dissipation channel are respectively connected to the inlet and the outlet, and the heat dissipation channel is spirally wound around the outer periphery of the mounting port.

[0008] By adopting the above technical solutions, the flow efficiency and heat exchange area of ​​the coolant are improved, ensuring that heat can be continuously and evenly removed from the outer periphery of the workpiece, effectively avoiding local overheating and cooling dead zones, thereby significantly improving the heat dissipation efficiency and stability of the cooling system.

[0009] Preferably, the outer wall of the stamping platform is provided with a feed inlet and a discharge outlet. The feed inlet is directly opposite the water inlet, and the discharge outlet is directly opposite the water outlet. Both the feed inlet and the discharge outlet are connected to the mounting groove. The feed inlet is used for the passage of the water inlet pipe, and the discharge outlet is used for the passage of the water outlet pipe.

[0010] By adopting the above technical solution, a precise, smooth and concealed channel is provided for the connection of cooling pipes. This not only effectively avoids the loosening or wear of external pipes due to vibration or spatial interference during the stamping process, greatly improving the reliability and safety of the system, but also makes the overall structure of the equipment more compact and neat, facilitating on-site installation, maintenance and pipe replacement.

[0011] Preferably, the stamping platform also includes a conveyor belt, the stamping platform is provided with a clearance opening located below the mounting groove, the stamping platform is provided with a discharge port connected to the mounting port and the clearance opening, the conveyor belt passes through the clearance opening, and the conveyor belt is used to transport the workpiece falling from the discharge port.

[0012] By adopting the above technical solution, the cooled workpieces falling from the installation port are directly received and transported, achieving seamless connection and high automation of the stamping, cooling and conveying processes. This greatly improves the production cycle and efficiency, avoids secondary heat effects or surface damage that may be caused by manual transfer of workpieces, and ensures the stability of the production process and the consistency of the products through closed continuous operation.

[0013] Preferably, it also includes a support plate, which is slidably connected to the inner wall with the clearance opening facing downward, and the upper end of the support plate is used to abut against the workpiece.

[0014] By adopting the above technical solution, the support plate supports the workpiece. After the number of stamped pieces accumulates to a certain amount, the support plate slides away from the discharge port, and the accumulated stamped pieces fall onto the conveyor belt, which makes it easy to control the number of stamped pieces that are discharged each time to be consistent.

[0015] Preferably, it also includes a positioning strip, which is fixedly connected to the inner wall of the mounting opening.

[0016] By adopting the above technical solution, precise and reliable radial positioning and clamping are provided for the workpiece, effectively limiting any displacement or vibration of the workpiece during high-speed stamping and cooling, ensuring forming accuracy and cooling uniformity. At the same time, its simple structure also has a guiding function, which facilitates the quick insertion and removal of the workpiece, improving the smoothness and efficiency of production.

[0017] Preferably, there are multiple positioning strips, and the multiple positioning strips are arranged at intervals along the circumference of the mounting opening.

[0018] By adopting the above technical solution and setting multiple positioning strips at intervals along the circumference of the mounting opening, uniform and multi-point positioning and support of the outer circumference of the workpiece is achieved, which effectively avoids workpiece surface damage or deformation caused by single-point stress concentration. At the same time, a uniformly distributed heat dissipation gap is formed between the workpiece and the inner wall of the mounting block, ensuring that the coolant can circulate around the workpiece for efficient and uniform heat exchange, which significantly improves the cooling effect and the consistency of product dimensions.

[0019] Preferably, the inner wall of the mounting port is provided with a groove, the positioning strip is embedded in the groove, and the end of the positioning strip away from the bottom of the groove is provided with a guide surface. The distance from the guide surface to the bottom of the groove decreases as the height increases.

[0020] By adopting the above technical solution, the workpiece is automatically guided to center when it is placed in, achieving fast and accurate self-positioning, which greatly simplifies the feeding operation and improves the production cycle and automation level.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By integrating the mounting block with heat dissipation channels into the stamping platform, the coolant can flow directly in the closed channels surrounding the workpiece, achieving precise and efficient cooling of the outer periphery of the workpiece during high-speed stamping. This effectively removes the instantaneous heat generated during stamping and significantly reduces the deformation, dimensional deviation, and microstructure changes of the workpiece caused by temperature rise, thereby improving the processing accuracy, surface quality, and consistency of mechanical properties of the product. 2. It improves the flow efficiency and heat exchange area of ​​the coolant, ensuring that heat can be continuously and evenly removed from the outer periphery of the workpiece, effectively avoiding local overheating and cooling dead zones, thereby significantly improving the heat dissipation efficiency and stability of the cooling system. 3. It provides precise and reliable radial positioning and clamping for the workpiece, effectively limiting any displacement or vibration of the workpiece during high-speed stamping and cooling, ensuring forming accuracy and cooling uniformity. At the same time, its simple structure also has a guiding function, facilitating the quick insertion and removal of the workpiece, and improving the smoothness and efficiency of production.
