Description

Technical Field

[0001] The utility model relates to the technical field of segment bolt bending, in particular to a segment bolt bending tool. Background Art

[0002] Segment bolts are a special fastener used to connect segments during shield tunneling in railway construction. Several arched segments can be connected into an arc through multiple segment bolts, which plays a role in connecting and fixing the supporting tunnel surface. Existing segment bolt bending tools are mostly one-piece structures. The punch head cannot be replaced and the base distance cannot be adjusted. Therefore, the tooling cannot meet the bending processing operations for segment bolts of different sizes, resulting in poor adaptability of the tooling and a relatively single processing type. In addition, when the segment bolts are subjected to force in the middle, the two ends of the segment bolts are very likely to curl up and buckle inward, resulting in poor segment bolt forming effect.
