The invention discloses a rolling mill, on which a supporting roll is rotated and matched by a first supporting device, and the supporting roll is positioned on the rack directly above the supporting roll, and the roller is arranged on the rack by a second supporting device; the roller is a cylindrical structure, and the outer circular surface of the roll is composed of two symmetrical conical surfaces which intersect with each other. In the middle of the roll, the middle of the roll is big and the two ends are small, so the rotating roll can roll the upper plate of the sheet metal; the distance between the supporting roll and the roll can be adjusted, and the supporting roll and the roll rotate relative to each other. When the sheet metal passes through the gap between the supporting roll and the roll, the roll is formed. The mill can not only continuously roll out the blank section, greatly improve the efficiency of rolling tool blank, but also from the middle to both sides of the rolling, not only rolling out two billet sections at the same time, but also make the material extend from the middle to both sides, thus effectively reducing material waste, but also reliable guarantee the consistency of the tool blank, which is conducive to the smooth progress of subsequent mechanized grinding.
【技术实现步骤摘要】
一种轧机
本专利技术涉及一种特别用于轧制菜刀等坯体的轧机。
技术介绍
菜刀是常用的生活用品,生产菜刀时需要先制出坯体。目前生产刀坯的方式主要有两种:第一种,采用磨削的方式在板材上磨削出刀坯的斜面。第二种,采用轧机单个轧制出刀坯,如图1和2所示,轧机的轧辊4为圆柱形结构,在轧辊4的外圆面沿周向开有一个轧制凹槽4a,该轧制凹槽4a的长度与菜刀长度大致相当,轧制凹槽4a的深度逐渐增大。轧制刀坯时,板材在轧机的轧辊与支撑辊之间移动,轧辊4转动轧制刀坯,并从菜刀的刀背向刀尖方向轧制成型,来回轧制4-5次后通过校平得到单个的刀坯。现有轧辊的缺陷是:1、一次只能轧制一个刀坯,效率很低;2、轧制时板材从刀背向刀尖方向延伸,由于阻力逐渐减小,最后会在刀尖处形成不需要的飞边,剪掉该飞边既费时又浪费材料,并且刀坯的一致性差,不利于后面的磨削工作顺利进行。
