斜辊矫直机有四种基本型式:二辊式、多辊交错式、六辊式和313式。上述各种矫直机都具有各自的优缺点。为了能正确地选择,必须根据管、棒的平直度,表面光洁度和矫直速度来考虑被矫材料的种类和对最终产品的要求。平直度平直度取决于所选择的矫直机型式,可达到的商品平直度为1/750和1/5000。上面所说的平直度是指沿已知长度的中心线偏差,即长度除以偏差(Arrow 法)。然而,另一种表示平直的方法是“全指示读数”系统(TIR),也就是当圆棒在中心距为1米的 V
Skew straightener has four basic types: two-roll, multi-roll staggered, six-roll and 313-style. The various straightening machines have their own advantages and disadvantages. In order to be able to make the right choice, the type of material to be straightened and the requirements for the final product must be taken into account according to the flatness of the tube, the stick, the surface finish and the straightening speed. Straightness Straightness depends on the type of straightener selected, with achievable flatness of 1/750 and 1/5000. The flatness referred to above is the centerline deviation along the known length, which is the length divided by the deviation (Arrow method). However, another method of indicating flatness is the “full-indication reading” system (TIR), ie when the rod is at a center of 1 meter V
