A high-speed wire water-cooled nozzle includes the nozzle main body, a nozzle core is arranged in the right end of the nozzle main body, a water-cooled cylinder is arranged on the left side of the nozzle core and in the main body of the nozzle, the axis line of the water-cooled cylinder body and the axis line of the nozzle core are in the same water line, the inner diameter size of the water-cooled cylinder body is equal to the inner diameter size of the nozzle core, the left side of the water-cooled cylinder body and the upper part of the left end head of the nozzle main body. An end cover is provided; a guide roller is arranged below the end cover and at the lower part of the left end of the nozzle main body; the lowest part of the upper end surface of the guide roller is higher than the lowest part of the inner wall of the water-cooled cylinder; the high-speed wire entering the water-cooled nozzle enters the nozzle main body through the nozzle core, and then the water-cooled cylinder body is treated for cooling, and finally is conveyed to the outside of the nozzle main body through the guide roller, because the upper end surface of the guide roller is higher than the inner wall of the nozzle It is higher than the water-cooled cylinder, so the whole process of high-speed wire hanging in the water-cooled cylinder ensures that the water-conducting holes in the water-cooled cylinder can cool the high-speed wire and make the product meet the requirements.
【技术实现步骤摘要】
一种高速线材水冷喷嘴
本技术涉及高速线材生产加工设备,特别涉及一种高速线材水冷喷嘴。
技术介绍
高速线材是指用高速轧钢机轧制的线制钢材,生产过程中,需要通过冷却水箱不断地对轧制后的高速线材进行降温处理,确保产品符合生产要求。现有技术中的水冷喷嘴存在着以下问题:轧制后的高速线材在通过冷却喷嘴时,由于自身的重力会与水冷喷嘴的内壁相接触,高速移动的过程中会产生摩擦,长时间使用后水冷喷嘴容易受损,导致了水冷喷嘴的使用寿命降低;高速线材通过水冷喷嘴时,由于下端全程与水冷喷嘴的内壁相接触,故导致该接触面的冷却效果差,使得生产的高速线材无法满足要求。
技术实现思路
本技术目的是提供一种高速线材水冷喷嘴,解决了以上技术问题。为了实现上述技术目的,达到上述的技术要求,本技术所采用的技术方案是:一种高速线材水冷喷嘴,包括喷嘴主体;其特征在于:所述喷嘴主体右端头内设置有喷嘴芯;所述喷嘴芯的左侧、在喷嘴主体内设置有水冷筒体;所述水冷筒体的轴心线与喷嘴芯的轴心线处于同一水线;所述水冷筒体的内径尺寸等于喷嘴芯的内径尺寸;所述水冷筒体的左侧、在喷嘴主体左端头的上部设置有端盖;所述端盖的下方、在喷嘴主体左端头的下部设置有导辊;所述导辊上端面的最低处高于水冷筒体内壁面的最低处。优选的:所述喷嘴芯的右端头设置有锥形导孔。优选的:所述水冷筒体通过紧固螺钉固定在喷嘴主体内;所述水冷筒体内壁上均匀设置有导水孔。优选的:所述导辊包括旋转滚轮;所述旋转滚轮外壁面的中间位置设置有线材凹坑;所述线材凹坑上端面的最低处高于水冷筒体内壁面的最低处2mm;所述旋转滚轮通过轴承旋转设置在销轴上;所述销轴固定在喷嘴主体 ...
