为积极配合轴承行业技术改造和设备的更新改造,提高轴承毛坯精度材料利用率。我公司组织研制生产的D51系列新结构倾斜式辗环机,受到广大客户的热情关注。

D51型辗环机品种齐全(见表)。普通型(D51Q-160D;D51Q-250D;D51Q-350D等)可供生产中窄系列轴承套圈毛坯;加宽型(D51Q-160E;D51Q-250E;D51Q-350E等)适合生产宽系列轴承毛坯,配有摆动式端面支承机构,具有足够的压力和驱动扭矩,配有摆动式、平衡式端面支承机构,具有足够的压力和驱动扭矩,能获得多种类型的大宽度毛坯。此外,接用户要求,可提供气动或液压两种压力系统。

D51型辗环机,结构新颖合理,吸取了用户使用经验,采用了部分引进设备的优点,选取新的配套件;滑块引导面长达行程的5-6倍,断面呈矩形,受力合理,导向精度高,使用寿命长;气缸选用国际标准型缸采用的聚氨脂Yx型密封圈,密封可靠,耐磨损,运动阻力小;精辗机构采用同步带传动,操作轻便,工作稳定,可调范围大;主轴轴承的选用和分布比较合理,辗压轮旋转精度高;下支承部分用楔铁固定在矩形框内,调整维修十分方便;下支承轴承有良好的密封,保证在恶劣环境下正常工作;选用了标准型减速器和Y型电机,两者置于同座底上,结构紧凑,安装维修方便;压缩空气经消声器释放,消除了噪声污染。

D51型辗环机辗压轮系采用涨圈固定,轴向定位精度高,简化了辗压轮的机械加工;下支承轴端圆锥孔后面设有方孔,辗压辊与下支承轴的联接可靠,更换容易,减少了非生产性工作消耗,提高了劳动生产率。

D51型辗环机主要零部件采用铸造钢和优质合金钢材制造,并经过合理的热处理;床身、底座等大件为钢铁焊接结构,刚性好,自身较轻、造型清晰美观。出厂前每台设备均经过运行试验和精度检查。

本公司近几年研制的400、630和800型大型号辗环机,受到化工法兰行业的普遍欢迎。不管是45钢法兰,还是不锈钢法兰,经辗扩成形后,车削余量少,圆整度好,材料利用率提高明显,远销全国各地、东南亚等法兰厂家,得到一致好评。

本公司重视销售后的产品服务,负责产品的调试,积极为客户提供备品备件。本公司使用说明书附有设备的机械零件目录,用户可按需要提出图号、零件名称和数量,本公司可代办邮寄和托运。

用户如有特殊需要,本公司可组织设计制造。本公司热忱欢迎广大用户提出宝贵意见,惠顾本公司。

To cooperate with the technical change of bearing industry amd update of equipment, improve accuracy of bearing cast and forging cast and improve utilization of raw material, our company designs and develops D51 series new-structure tilt rolling ring machine and this series products are welcomed by a wide range of users. The D51 rolling ring machines have a various models(see the following list),they are equipped with supporting structure with swinging and balancing end surface to get enough pressure and driving torque.various cast with large width can be produced by these machines.Two pressure sysstems,pneumatic and hydraulic, can by provided according to the requirements of user. The structure of D51 rolling loop machine has a reasonable and novel structure,experiences from user and advantages of imported machine are considered in its design. New accessories are selected for this machine.including:long guide surface of sliding block and the length is 5~6 times of journey,rectangle section to get a resonable force distribution,high accurate guiance and long service life. Polyurethane Yx O-ring which is used for international standard cylinder selected,itshas a reliable sealing and abrasive resistance performance and moves with lower resistance. The fine-grinding structure is driven by a synchronizde belt and runs smoothly,a wide adjusting range is available. The selection and distribution of main shaft bearing is reasonable and the rotating accuracy of rolling wheel is high. The lower supporting part is part is fixed into a rectangle frame with a wedge and it is easy to be adjusted and repaired. The lower supporting bearing well to make it working normally in poor condition. Standard reducer and Y mode motor are seleceed and installed on a same base to form a compacted structure for a consideation of installtion and maintenance. The compressed air is exhausted through a muffler to eliminate noise pollution. The rolling wheel of D51 rolling loop machine is fixed with an expansion ring and its axial locating accuracy is high so the processing difficult of rolling wheel is reduced. A square hole locates at the cone hole in eng of lower support so the rolling roller is easy to be connected with lower supporting so the rolling roller is easy to be connected with lower supporting shaft and replaced,such structure can waste of non-production time and improve productivity. The main parts of D51 rolling loop machine are made of cast steel and high quality alloy steel and those material are hot-treated reasonably.The machine base and body are weld-formed by steel plate,such structure is light and has a good rigidity. Each machine is carried with trial run and accuracy inspection before shipping. The rolling loop product manfacturing in our company are distributed in various districts in China and Southeast Asia. Our company regards after-service and is responsible for setup setup of nachine. We provide spare parts for our customer initively. A part list is attached in the working instrution provided by our company and we can mail the part to user after get the information of drawing number,part name and quantity. We can design and manufacture product according to the special requirements of customer. We welcome any suggestions from user and please do hesitate to contact us.
