Manufacturing method of bucket, bucket and operation machine

ZHANG XIANGZHONG

The invention discloses a manufacturing method of a bucket, the bucket and an operation machine, and the manufacturing method comprises the steps that a mounting groove is formed in the circumferential direction of a bucket connecting hole, a wear-resisting ring is embedded into the mounting groove of the bucket connecting hole, and the whole is put into a vacuum hot pressing sintering device to be sintered; the wear-resistant ring is made of a ceramic matrix material, and the size of the wear-resistant ring is matched with that of the mounting groove; heat preservation is conducted at the metal phase transition temperature of the bucket connecting hole, and after a preset time, the bucket connecting hole is heated to the diffusion bonding temperature at the preset heating speed; and vacuum heat preservation is conducted at the diffusion bonding temperature, and after the needed reaction time is kept, cooling is conducted, and the bucket connecting hole embedded with the wear-resisting ring is taken out. By means of good abrasion resistance and self-lubricating performance of the abrasion-resistant ceramic, the abrasion resistance and the lubricating performance of the bucket and the bucket rod installation mechanism can be improved, and therefore the service life of the whole component of the bucket can be prolonged.

本发明公开了一种铲斗的制作方法、铲斗及作业机械，该制作方法包括：铲斗连接孔的周向设置有安装槽，将所述耐磨环嵌入所述铲斗连接孔的安装槽中，并整体放入真空热压烧结装置中进行烧结；所述耐磨环由陶瓷基体材料制成，所述耐磨环的尺寸与安装槽相匹配；在所述铲斗连接孔的金属相变温度进行保温，经过预设时间后，以预设加热速度加热到扩散连接温度；以所述扩散连接温度进行真空保温，在保持所需要的反应时间后，降温并取出嵌有所述耐磨环的所述铲斗连接孔。通过耐磨陶瓷的较好的耐磨性和自润滑性能，能够提升铲斗与斗杆安装机构处的耐磨性和润滑性，从而能够延长铲斗整体部件的使用寿命。
