Abstract
Description
Technical Field
[0001] This utility model relates to the field of forging die technology, specifically a forging die for irregularly shaped forgings. Background Technology
[0002] Forging dies, as core process equipment in die forging production, use high temperature and high pressure to plastically deform metal billets, ultimately shaping them into the desired parts. These dies are typically made of high-strength alloy steel, possessing excellent heat resistance and wear resistance, and capable of withstanding repeated impact loads. On the die forging production line, forging dies directly determine the dimensional accuracy and mechanical properties of the product, and are a key factor in ensuring the stability of quality in mass production.
[0003] Current forging die designs have significant functional limitations: firstly, the cooling system is inefficient, severely impacting production cycle time and die lifespan; secondly, unreasonable demolding mechanisms easily lead to finished products sticking to the die or surface damage. These problems not only reduce production efficiency but also increase die maintenance costs. Therefore, we propose a forging die for irregularly shaped forgings. Utility Model Content

A water pump 43 is installed inside the U-shaped water tank 42. An outlet pipe 44 is fixed inside the outlet of the water pump 43.

[0025] Wherein: a connecting flange ring 8 is fixed at the front end of the circumferential surface of the water injection pipe 74, and a connecting flange ring 8 is fixed at the front end with evenly distributed connecting holes, and the water injection pipe 74 is connected to the external coolant pipeline by setting the connecting flange ring 8.

[0027] The working principle of the forging die for irregular forging provided by this utility model is as follows: After forging, the water pump 43 of the water injection component 4 is started, and the coolant in the U-shaped water tank 42 is pumped into the cooling chamber 41 inside the forming die 3 through the water outlet pipe 44. The workpiece in the die groove 9 is cooled down quickly for the first time through metal conduction. When the heated coolant returns to the U-shaped water tank 42 through the return pipe 45, the temperature sensor 51 of the first cooling component 5 monitors the water temperature in real time and links with the semiconductor refrigeration chip 52. Its cooling end continuously cools the return liquid, and the cooling fan 54 simultaneously forces the heat dissipation end of the semiconductor refrigeration chip 52 to dissipate heat. When the workpiece reaches the set temperature due to the initial cooling, the hydraulic rod 61 of the ejector component 6 pushes the connecting column 62 upward. Through the transmission cooperation between the threaded column 63 and the extrusion block 64, the four extrusion blocks 64 are synchronously and smoothly lifted along the support frame 65, removing the workpiece from the mold slot 9 without damage. After the workpiece is ejected, the electric telescopic rod 73 of the second cooling component 7 drives the annular tube 71 to rise to a preset height. The external cooling medium is injected into the annular tube 71 through the water injection pipe 74, and forms an atomized cooling curtain through the evenly distributed nozzles 72 to perform secondary gentle cooling on the surface of the workpiece. During the cooling process, the temperature sensor 51 and the PLC controller dynamically adjust the power of the semiconductor cooling chip 52 to ensure that the cooling medium is kept at a constant temperature. At the same time, the electric telescopic rod 73 automatically adjusts the height of the annular tube 71 according to the mold temperature feedback to optimize the cooling distance. After the two-stage cooling is completed, the components achieve the best balance between cooling efficiency and workpiece integrity through PLC collaborative control.
[0028] It is worth noting that the external PLC controller disclosed in the above embodiments is specifically a Siemens S7-200. The water pump 43, the thermoelectric cooler 52, the cooling fan 54, the hydraulic rod 61, the electric telescopic rod 73, and the temperature sensor 51 can be freely configured according to the actual application scenario. The external PLC controller controls the operation of the water pump 43, the thermoelectric cooler 52, the cooling fan 54, the hydraulic rod 61, and the electric telescopic rod 73 using methods commonly used in the prior art.
