Description
本發明係有關於一種線性滑軌素材之連續式近淨型軋延設備，特別是有關於一種四輥式軋延塑性加工之線性滑軌素材之連續式近淨型軋延設備。 The present invention relates to a continuous near-net type rolling device for a linear slide material, and more particularly to a continuous near-net type rolling device for a four-roll rolling plastic processing linear slide material.
目前常見的線性滑軌素材之抽線拉拔製造流程詳如圖1所示，首先將鋼線或棒材進行球化熱處理如圖2之球化組織(spheroidite)，以避免眼模抽線或軋輥拉拔過程中，因加工硬化造成滑軌內部產生微裂痕，圖3為碳鋼之時間-溫度-相變態曲線(time-temperature-transformation diagram)，球化溫度約700℃左右，由圖3得知變態完成所需時間需時18~24小時左右。鋼線或棒材球化處理完成後，進行矯直、清潔除鏽、抽線或拉拔製程，重覆上述步驟三次以上，將鋼線或棒材塑性加工成線性滑軌素材，再重新加熱進行正常化處理，以消除線性滑軌內部的球化組織，由於加熱過程沒有拘束力，線性滑軌容易產生翹曲或扭轉，因此正常化熱處理後，必須再進行一次線性滑軌素材矯直加工。 The current manufacturing process of the linear slide material drawing is shown in Figure 1. First, the steel wire or bar is spheroidized and heat treated as shown in Figure 2 to avoid spheroidite. During the drawing process of the roll, micro-cracks are generated inside the sliding rail due to work hardening. Figure 3 shows the time-temperature-transformation diagram of carbon steel, and the spheroidizing temperature is about 700 °C. It takes about 18~24 hours to know the time required for metamorphosis to complete. After the spheroidizing treatment of the steel wire or bar is completed, the straightening, cleaning, derusting, drawing or drawing process is repeated, and the above steps are repeated three times or more, and the steel wire or the bar is plastically processed into a linear sliding rail material, and then reheated. The normalization process is performed to eliminate the spheroidized structure inside the linear slide rail. Since the heating process is not restrained, the linear slide rail is prone to warp or twist. Therefore, after the normalization heat treatment, the linear slide rail material straightening processing must be performed. .
上述線性滑軌素材加工繁複，且每一次球化時間需時18~24小時左右，造成工時過非常長且加工成本太高。此外，球化時間非常長，容易造成表面發生脫碳情形，導致滑軌素材品質不良。 The above-mentioned linear slide material processing is complicated, and each spheroidizing time takes about 18 to 24 hours, resulting in a very long working time and a high processing cost. In addition, the spheroidization time is very long, and it is easy to cause decarburization on the surface, resulting in poor quality of the slide rail material.
