各种类型的柴油机和汽油机的连杆铜套是易损件。我们曾对铜套进行过压缩修复(见《农业机械技术》1966年第3期34页),可是由于铜套需要量大,用压缩修复的方法仍然不能满足需要,通过反复实践,我们又采用了挤压和焊补的方法,效果很好。挤压法把铜套放在压模内挤压(图1)利用铜的塑性变形,用缩小外径的方法,补偿磨损的内径,再经机械加工到所需尺寸,即可再用。例如2115、4115、4120、3115型柴油机的铜套内径和2105、1105
Various types of diesel engine and gasoline engine connecting rod copper sleeve is wearing parts. We have carried out compression repair of copper bushings (see “Agricultural Machinery Technology”, No.3, 1966, p. 34). However, due to the large amount of copper bushings, the method of compression repair still can not meet the need. Through repeated practice, we adopt The method of extrusion and welding repair, the effect is very good. Extrusion method The copper sleeve extrusion die (Figure 1) the use of plastic deformation of copper, with the method of reducing the outer diameter, wear diameter compensation, and then machined to the desired size, you can re-use. Such as 2115,4115,4120,3115 type diesel engine copper sleeve diameter and 2105,1105
