Abstract

The invention provides a machining method of a bearing bush positioning lip. The machining method of the bearing bush positioning lip comprises the following steps of: A, positioning a bearing bush material; and B, starting a positioning lip stamping knife and performing stamping vertically and downwardly to form the positioning lip from the half surface of a bearing bush by using the positioning lip stamping knife. According to the machining method of the bearing bush positioning lip, burrs can be prevented from being produced at the periphery of the positioning lip, bulging of an alloy surface of the bearing bush and alloy cracking and stripping phenomena are not caused during stamping, and burrs are not produced on the half surface yet when the radius in a next sequence is large.

Description

technical field [0001] The invention relates to a processing method of a bearing pad, in particular to a processing method of a positioning lip of a bearing pad. Background technique [0002] The traditional positioning lip is to use a punching knife to punch out a boss from the alloy surface of the bearing pad, that is, the inner surface of the bearing pad, to the outside after the bearing pad is formed. Traditional positioning lip processing adopts two methods: manual mold or automatic mold: [0003] 1. If figure 1 As shown, it is a manually operated positioning lip processing mold, which manually puts the bearing bush 3 into the positioning lip mold 2. At this time, the inner surface of the bearing bush is super obliquely upward, and the positioning lip punching knife 1 is installed on the handle of the upper mold. The lowering of the punching knife 1 punches the bearing bush 3 into the positioning lip insert 4, thereby forming a protrusion on the back of the bearing bu...
