Description

Technical Field

[0001] The utility model relates to the technical field of segment bolt processing equipment, in particular to a segment bolt punching device with protection. Background Art

[0002] In tunnel construction, there is a machine called a shield machine that is used for starting and excavating. It has the functions of excavating and cutting soil, transporting soil and assembling tunnel linings, etc. When the shield machine is lining the tunnel, it is assembled with several segments. The segments are connected and assembled by bolts to form a cylindrical pipe, thereby supporting the excavated tunnel. The bolts that connect and tighten the segments are called segment bolts. The segment bolts are divided into two types: straight and arc-shaped. The arc-shaped segment bolts need to be stamped. During stamping, the segment bolts are limited to the lower die with an arc-shaped depression, and the upper die with an arc-shaped protrusion is pressed down, so that the segment bolts can be stamped into an arc; but the segment bolts lack a protective structure during stamping, and are prone to displacement and slipping out of the stamping position, affecting the stamping efficiency. After the stamping is completed, they are easily embedded in the lower die, which is inconvenient to remove, resulting in reduced processing efficiency. Utility Model Content
