一、设备简介“滚拉法”也可以认为是冷拉和冷轧的综合方法。用一台冷拔机和一组滚动模配套而成。滚动模装在冷拔机的固定架上,两个辊子可以上、下调整,钢材通过两个辊子组成的孔型由冷拔机牵引,钢材的运动带着辊子转动,在适当的变形量下通过几次滚拉,产生出所需要的异型钢材。滚动模尺寸的大小和冷拔机的拉力是由异型材的尺寸决定的。异型材尺寸愈大或变形量和变形抗力愈大,所需要的滚动模尺寸和冷拔机的拉力也就愈大。现用冷拔机公称拉力为五吨,所配套的滚动模架外形尺寸为高×宽=450毫米×280毫米。
First, the device profile “Rolling Law” can also be considered as cold-drawn and cold-rolled integrated approach. A cold drawing machine and a set of rolling mold from the package. Rolling equipment in the drawing frame of the fixed rack, two rollers can be adjusted up and down, the steel through the two rollers composed of the hole drawing by the drawing machine, the movement of steel with a roller rotation, at the appropriate deformation Rolling through several times to produce the required profiled steel. The size of the rolling die and drawing machine pulling force is determined by the size of the profile. The larger the profile size or the greater the deformation and deformation resistance, the greater the required rolling die size and drawing force. Nominal pull cold drawing machine now used for the five tons, supporting the shape of the rolling frame height × width = 450 mm × 280 mm.
