Side Spray Cooling Mechanism and Cooling Method of Hot Forging Die Frame

Abstract

The invention discloses a side-spraying cooling mechanism and method for a hot-forging mould frame. The side-spraying cooling mechanism comprises a fixed sleeve and a spray head module, wherein the upper part of the spray head module is coaxially arranged in the fixed sleeve in a sleeved mode; the lower part of the spray head module extends to a position below the fixed sleeve; a spray nozzle is arranged on the side wall of one side of the spray head module; a spray cavity is arranged in the spray head module; a guide hole is formed in the side wall of the fixed sleeve; a guide block is arranged above the spray head module; the guide block is equipped with a perpendicular guide cavity and a horizontal guide cavity, which are through; and a spring is arranged above the guide block. The cooling method comprises the following steps: enabling the guide hole to be flush to the horizontal guide cavity in a mould-opening state, introducing cooling liquid into the guide cavity from the guide hole, spraying the cooling liquid from the spray nozzle, directly ejecting the cooling liquid onto a punch, enabling the guide hole to be staggered from the horizontal guide cavity after mould-closing,and stopping spraying cooling liquid. The side-spraying cooling mechanism is mounted under an upper mould moulding board of the hot-forging mould frame, optimizes the cooling effect, prolongs the service life of the mould, is better in cooling effect, and is more convenient and quick.

Description

technical field [0001] The invention relates to a side spray cooling mechanism and a cooling method of a hot forging die frame, belonging to the technical field of hot forging cooling. Background technique [0002] In traditional hot forging, the mold needs to be heated to about 200°C, and the mold is lubricated by spraying graphite suspension on the surface of the mold. After evaporation, the residual graphite acts as a lubricating medium at high temperature. The disadvantage of this lubrication method is that there will be a large amount of graphite powder, which will cause environmental pollution in the workshop. [0003] In the hot forging form with a large amount of water, the mold does not need to be heated, but it needs to be cooled in time to keep the mold at room temperature during the production process and rely on water vapor for lubrication during rapid forming. If the cooling is not timely, the mold and forgings will appear sticky. The contact phenomenon and th...

[0003] In the hot forging form with a large amount of water, the mold does not need to be heated, but it needs to be cooled in time to keep the mold at room temperature during the production process and rely on water vapor for lubrication during rapid forming. If the cooling is not timely, the mold and forgings will appear sticky. The phenomenon of contact phenomenon and the surge of ejection force greatly reduces the life of the mold, and sometimes even causes the product to fail to form. Therefore, cooling in the die and punch cooling devices are required for timely cooling

The disadvantage of this cooling method, which usually uses a hose to directly spray a large amount of cooling water, is that when the cooling water is used, the cooling hose is affected by the up and down movement of the mold frame, and the cooling is often not timely, which is time-consuming and laborious, and the effect is not good. , most of the hoses need to extend into the forming area of ​​the mold base, which makes the walking beam unable to realize full automation and often alarms
