Spur gear with a wheel the maximum of precision forging
Deformation mode of a mobile gear precision forging, in the hub cavity and tooth cavity filled at the same time, the forging deformation force minimum, this is because the whole process in the forging, forming a hub teeth forming the Department of diversion, play lower deformation Force 14, Volume 5, Mechanical Engineering role. In the second and third metal flow mode, gear precision forging, precision teaching deformation force will increase. This is because the metal flow in the second mode, the hub forming the Department of diversion does not exist, all the radial inflow of metal tooth cavity, the deformation resistance increases liquidity in the third mode shape deformation, due to tooth cavity is filled,[link widoczny dla zalogowanych], the metal tooth cavity Die by the compression effect on the back end into the hub cavity axial force increases the deformation 3) from analysis of H, / s \severe, l and area 2, 1 and 5, the shear zone between the most serious tear, 4 District and the mold contact surface friction and wear the most serious; metal flow mode in the second gear precision forging, 4 zones The most intense deformation, and 3 in Area 3, torn between the most severe cut, 4-zone contact with the mold surface friction and wear the most serious; metal flow in the third mode shape gear fine teaching, l most intense deformation zone, l District,[link widoczny dla zalogowanych], and 3 the most serious between the shear tear, 5 areas of contact with the mold surface friction and wear the most serious; the data for precision forging die design and analysis of defect information. 4) consumed by the comparison of three flow patterns the power we can see that the most uniform deformation of the first flow pattern, power consumption of pure plastic deformation and shear power of the minimum. In addition,[link widoczny dla zalogowanych], the use of curves in Figure 5 can be optimized billet size, parts size and control the deformation process. For example, the stock and part size as far as possible to ensure that both tooth cavity filled cavity and the hub. If the metal too much, tooth cavity is full. excess metal squeezed into the hub cavity, the deformation force will increase. 5) The upper limit of the friction power in the total proportion of larger recommended the adoption of appropriate forging lubricant to reduce the required deformation force. But the blank and die surface of die wall friction and the contact should not be too small, otherwise the structure with floating die is pointless. References 1 Lin Zhiping and so on.
