Description
本発明は、金型鋼加工の分野に関し、特に、金型鋼加工設備用の伝動装置に関する。 The present invention relates to the field of structural steel processing, and particularly to a transmission device for a structural steel processing facility.
金型鋼は、コールドパンチダイス、ホットパンチダイス、ダイカストダイスの製造によく使用され、その硬度が高いため、加工が中々し難い。加工中に、それに作用する機器がずれて移動することがある。 Mold steel is often used in the manufacture of cold punch dies, hot punch dies, and die casting dies, and its high hardness makes it difficult to process. During processing, the equipment acting on it may shift and move.
切断を容易にするため、従来技術は、よく熱処理によって金型鋼加工の困難さを低減している。ただし、金型鋼自体にも熱疲労特性があり、加工中の熱処理、特に熱処理焼入れ温度は、金型鋼切断面のオーステナイト結晶粒径、合金元素の固溶度及びワーク表面構造の均一性に影響を与え、更に金型鋼ワーク完成品の全体的な熱疲労性能に影響を与える。 In order to facilitate cutting, the prior art often reduces the difficulty of processing the structural steel by heat treatment. However, the structural steel itself also has thermal fatigue characteristics, and the heat treatment during processing, especially the heat treatment quenching temperature, affects the austenite crystal grain size of the cut surface of the structural steel, the solid solubility of the alloying elements, and the uniformity of the work surface structure. In addition, it affects the overall thermal fatigue performance of the finished product of the structural steel work.
特に、従来の金型鋼ワークが加工中に熱処理装置を出た後、ワークの温度は急激に低下し、表面の結晶構造に影響を与えることがあり、結晶構造が内向き熱変成層に異化し、ワークの応力強度に影響し、加工中のワークを変形、割れやすくする。 In particular, after the conventional shaped steel workpiece leaves the heat treatment apparatus during machining, the temperature of the workpiece drops sharply, which may affect the crystal structure on the surface, and the crystal structure is catabolized into an inwardly thermally denatured layer. , Affects the stress strength of the work, and makes the work during machining easily deformed and cracked.

したがって、上記の装置を用いることにより、以下の前処理手順が実現でき、加工時のワーク表面強度が確保できる。 Therefore, by using the above device, the following pretreatment procedure can be realized, and the work surface strength at the time of processing can be ensured.
まず、加工待ちの金型鋼ワークを２５０℃〜３５０℃に熱処理し、熱処理された金型鋼ワークを搬出する。 First, the mold steel work waiting to be processed is heat-treated to 250 ° C. to 350 ° C., and the heat-treated mold steel work is carried out.
そして、搬出後の金型鋼ワークの上下両面にセラミック発熱体を設置し、前記セラミック発熱体から放出する温度で金型鋼ワークの温度を２５０℃以上に保ち、金型鋼ワークを１時間当たり３０℃を超えない焼鈍し速度でゆっくりと焼鈍しさせる。 Then, ceramic heating elements are installed on both the upper and lower sides of the mold steel work after being carried out, the temperature of the mold steel work is kept at 250 ° C. or higher at the temperature discharged from the ceramic heating element, and the mold steel work is kept at 30 ° C. per hour. Anneal slowly at an annealing speed that does not exceed.
続いて、圧延前に前記金型鋼ワークの表面に液体媒体を塗布し、前記液体媒体は２５０℃までに加熱された油性媒体で、前記油性媒体に金属粉末も混ぜされ、前記金属粉末はナノレベルの鉄粉末、レニウム粉末、チタン粉末、タングステン粉末、マンガン粉末、クロム粉末、マグネシウム粉末のいずれか１つまたはそれらの混合物を含む。 Subsequently, a liquid medium is applied to the surface of the mold steel work before rolling, and the liquid medium is an oil-based medium heated to 250 ° C., and metal powder is also mixed with the oil-based medium, and the metal powder is nano-level. Includes any one or a mixture of iron powder, renium powder, titanium powder, tungsten powder, manganese powder, chromium powder, magnesium powder and the like.
最後に、前記金型鋼ワークに水平方向の圧延加工と垂直方向の圧延加工を施し、前記圧延加工中に前記圧延機の各ロール間の距離は前記金型鋼ワークサイズの８０％〜９０％の間となっている。このように前処理されたワークは、その表面に炭素圧延が析出され、鉄、レニウム、チタン、タングステン、マンガン、クロム、マグネシウム等のナノ粉末が金型鋼表面のメタルキー電極と相互作用し、前記圧延表面に新たに緻密な保護層を形成し、この保護層は、圧延工程により金型鋼ワーク表面に形成されたオーステナイトまたは変成層表面に融着する。本発明の前処理後の金型鋼ワーク表面のオーステナイトまたは変成層の物理的性質が変化し、ワーク表面の硬度と脆性が大幅に改善され、変形や亀裂が発生しにくくなり、加工が容易になる。 Finally, the mold steel work is subjected to horizontal rolling and vertical rolling, and the distance between each roll of the rolling mill during the rolling is between 80% and 90% of the shape of the mold steel work. It has become. In the work thus pretreated, carbon rolling is deposited on the surface thereof, and nanopowder of iron, renium, titanium, tungsten, manganese, chromium, magnesium and the like interacts with the metal key electrode on the surface of the structural steel. A new dense protective layer is formed on the rolled surface, and this protective layer is fused to the austenite or metamorphic layer surface formed on the surface of the structural steel work by the rolling process. The physical properties of the austenite or metamorphic layer on the surface of the structural steel work after the pretreatment of the present invention are changed, the hardness and brittleness of the work surface are greatly improved, deformation and cracks are less likely to occur, and processing becomes easier. ..
本発明は、ローラ搬送装置に設けられたセラミック発熱体によって加工待ちの金型鋼ワークを第１温度範囲内に維持し、それによって金型鋼ワーク表面の結晶特性が温度の急激な変化によって変化しないことを保証することができる。また、本発明はナノ金属粉末を含有する液体媒体を、媒体ブラシヘッドを通して、ワーク表面の圧延機に接触しようとしている場所に塗布する。したがって、本発明の金型鋼が圧延中に、媒体によって、金型鋼ワークの圧延変形中のオーステナイトの形成を回避し、剪断変形層の厚さを減らし、その後の加工処理を容易にすることができる。 In the present invention, the ceramic heating element provided in the roller transfer device keeps the structural steel work waiting to be machined within the first temperature range, whereby the crystal characteristics of the surface of the structural steel work do not change due to a sudden change in temperature. Can be guaranteed. Further, in the present invention, a liquid medium containing nanometal powder is applied through a medium brush head to a place on the surface of the work where it is going to come into contact with a rolling mill. Therefore, during the rolling of the structural steel of the present invention, the medium can avoid the formation of austenite during the rolling deformation of the structural steel work, reduce the thickness of the shear deformed layer, and facilitate the subsequent processing. ..
