HRB bearing small make up to introduce bearing ring precision cold rolling technology for you

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Precision cold rolling technology is at room temperature to annular rotary parts using extrusion and plastic deformation of the finished products were obtained a cold forming method. Precision cold rolling can make the size and shape of the workpiece maximize the theoretical value of close to finished products. Its advantages are: 1. Can significantly improve the efficiency of material utilization and processing. Compared with the traditional approach of turning processing, precision processing of cold rolling can make the material saving rate increased by 10% ~ 15%, so as to realize the machining of bearing ring, reduce the processing cost. 2. Can improve the quality of the finished product. Due to the rolling way, the parts inside the metal flow is continuous and complete, the grain size of the metal is homogeneous and small, organization is relatively compact, so the strength of the parts. At the same time, because of the existence of finished parts surface residual stress also make parts after heat treatment deformation is small. 3. Can save energy, improve the working environment. Compared with forging die, precision rolling equipment needed for the tonnage is small, can significantly reduce the noise when processing, energy saving effect is obvious. Compared with the cutting mat, the noise and dust. Rolling workpiece, rolling wheel to drive the workpiece rotation, solid core roller with feed unit driven support roller extrusion of the workpiece, so as to realize the workpiece rolling. From the conditions of the workpiece, meet the conditions of forming are: horizontal direction of the workpiece with the feed force applied direction of phase equilibrium, it is necessary for stable deformation; Vertical direction of workpiece to be greater than or equal to the work piece deformation and the launch of the force, this is the condition of rolling to continue. The above two force is a supporting wheel or core roller and workpiece contact arc method to force component in horizontal and vertical direction. Plastic deformation can be ensured when the supporting wheel feed across the wall thickness of workpiece, its deformation effectively. Moreover, feeding depends on the drive power of the rolling wheel, supporting wheel of thrust, rolling wheel and core roller radius of curvature. Feeding determines the size of the support roller or core roller and workpiece contact arc length, the corresponding is the workpiece deformation produced by the normal force, the longer the contact arc, the greater the deforming force. Due to the rolling wheel, core roller and workpiece inside and outside the circle of curvature radius is different, every time feed produced both inside and outside the workpiece deformation is not equal. On the cylindrical workpiece deformation should be greater than the deformation of inner circle, as the rolling process, both inside and outside round the difference of the deformation will decrease. Roundness stick is used to control the degree of cylindrical workpiece. In the rolling process of workpiece, roundness stick close to the cylindrical workpiece, along with the increase of workpiece diameter retreat, and to provide a constant round of bending moment. Roundness stick use can ensure workpiece rolling process stability, effectively reduce the vibration in rolling, and extend the life of the mould and machine tool spindle bearing. At present, a German BADDUBEN abroad pure rolling equipment is mainly URAW series and Japanese KYOEI CRF and which is the series of the company. They represent the two technical routes: BADDUBEN adopt vertical layout, the electro-hydraulic position servo control system to improve the rolling accuracy, and KYOEI company adopts horizontal layout, rough rolling, and a combination of the whole diameter workpiece to improve the size precision of the workpiece.
