徐州NSK轴承61917N套圈成型的方式

目前，环件成形方法主要有徐州NSK轴承锻造、车削、冷轧和冷（温）挤等。通过触摸轴承上的钢印，可以更快、更准确地识别轴承。如果这些***是用手碰的，就不会碰了。然而，钢印的存在可以用钉子触摸。在上述成形方法中，锻造是应用**广泛的，约占总产量的80个百分点。对于一些小的一般类型，锻造是**广泛使用的。本产品可与杆（管）材料直接旋转。

At present, ring forming methods mainly include forging, turning, cold rolling and cold (warm) extrusion of Xuzhou NSK bearings. By touching the steel stamp on the bearing, the bearing can be recognized more quickly and accurately. If these stamps were touched by hand, they would not be touched. However, the existence of steel stamps can be touched by nails. In the above forming methods, forging is widely used, accounting for about 80 percent of the total output. For some ***all general types, forging is widely used. This product can rotate directly with rod (tube) material.

通过锻造，弥补了徐州NSK轴承金属内部缺点，改变了金属结构，金属流线分布合理，金属密封性好。当轴承识别出轴承的真假时，通过触摸轴承上的钢印，可以更快、更准确地识别轴承。如果你用手碰它，***就不会被碰，但是如果你用指甲轻轻地碰它，你就能感觉到。锻造技术在轴承成形过程中获得了广泛的应用。能完成小产品从内径20毫米到5000毫米的特点。加工大型产品。常用的锻造方法有热锻、冷锻和温锻。徐州NSK轴承热锻是我国的主要方法。

By forging, the inner defects of Xuzhou NSK bearing metal are remedied, the metal structure is changed, the metal streamline distribution is reasonable, and the metal seal is good. When the bearing recognizes the true or false of the bearing, it can recognize the bearing more quickly and accurately by touching the steel mark on the bearing. If you touch it with your hand, the stamp will not be touched, but if you touch it lightly with your nails, you can feel it. Forging technology has been widely used in bearing forming process. Can complete ***all products from the inner diameter of 20 mm to 5000 mm characteristics. Processing large-scale products. The commonly used forging methods are hot forging, cold forging and warm forging. Hot forging of Xuzhou NSK bearings is the main method in China.

由于热锻设备的不同，热锻工艺可分为自*由锻造工艺、压锻工艺、平锻工艺和高速镦粗工艺。当轴承识别出轴承的真实性时，通过触摸轴承上的钢印，可以更快、更准确地识别轴承的真实性。如果用手触摸，***是不可触摸的，但可以用钉子触摸***。

Due to the difference of hot forging equipment, hot forging process can be divided into self-forging process, press forging process, flat forging process and high-speed upsetting process. When the bearing recognizes the authenticity of the bearing, it can recognize the authenticity of the bearing more quickly and accurately by touching the steel mark on the bearing. Stamps are not touchable if touched by hand, but they can be touched by nails.

冷轧技术是提高材料利用率、徐州NSK轴承金属结构致密性和保持金属流动线性的***技术。这是一种无芯片处理方法。理论上，冷轧产品可以直接进行热处理和磨削而不需要车削。目前，冷轧技术主要应用于中小型深沟球轴承，其主要工艺流程如下：

Cold rolling technology is an advanced technology to improve material utilization rate, metal structure compactness of Xuzhou NSK bearing and keep metal flow linearity. This is a chipless processing method. In theory, cold rolled products can be directly heat treated and grinded without turning. At present, cold rolling technology is mainly applied to ***all and medium-sized deep groove ball bearings, and its main technological process is as follows:

锻造毛坯（环）-车削（开槽）-轧制（开槽和倒棱）-全直径-软磨端

Forging blank (ring) - turning (slotting) - rolling (slotting and chamfering) - full diameter - soft grinding end

采用冷滚锻工艺时，徐州NSK轴承产品精度不仅受设备精度的影响，而且受成形模精度的影响。

When adopting cold rolling forging technology, the precision of Xuzhou NSK bearing product is affected not only by the precision of equipment, but also by the precision of forming die.
