当前市场需求量较大的精密管材口径大都集中在18mm～76mm之间,具有口径偏小、质量较轻,表面质量要求严格等特点,因此这类管材在尾部出矫直机主机后采用夹送辊将被矫管材送入走钢线以内,由于当前的夹送辊角度不可调且和矫直中心线垂直,常常会将旋转前进的管材划伤,且在夹送之前上辊和管材脱开,达不到抑制管材甩动的目的,严重影响了管材矫直质量的提高。可调角度夹送辊由于具备夹送辊角度可调,下辊快速避让的功能,很好地解决了划伤管材表面、抑制管材甩动的问题,在某厂Ф80机组上发挥了效用,可以作为新上精密管材矫直机的参考。
The current market demand for large precision pipe diameter are mostly concentrated in the 18mm ~ 76mm, with a smaller caliber, lighter quality, surface quality requirements and other characteristics, so this type of pipe in the rear of the straightening machine host using pinch The rollers feed the straightening material into the tipped wire. As the current pinch roller angle is not adjustable and is perpendicular to the centerline of the straightening, it is often the case that the pipe on which the advancement is to be scored is scratched and the top roller and tubing are disengaged before pinching , Can not achieve the purpose of inhibiting the pipe from swinging, which seriously affects the improvement of the pipe straightening quality. Adjustable angle pinch roller as a result of adjustable pinch roll angle, the next roll quickly avoid the function of a good solution to the scratched pipe surface, inhibit the pipe swinging problem, in a factory Ф80 units have played a role, you can As a new precision tube straightening machine reference.
