Abstract

The invention discloses a punch die and solves the problem that the punched holes are likely to misalign and the problem that the depth and direction of the holes are not in accordance with design requirements in the conventional punch tool. In the punch die, expansion rod connecting holes (7) are arranged on the outer circumference of the round top plate of a cylindrical body (1) at equal radian intervals, a pressure valve (5) and a handle (4) are arranged on the round top plate of the cylindrical body (1) respectively, a suction cup (8) is arranged on the bottom surface of the cylindrical body (1), and a suction rod (9) is arranged between the suction cup (8) and the pressure valve (5); and each expansion rod (2) consists of a sleeve body (17) and a rod body (12), the cylindrical body (1) has internal threads, the rod bodies (12) have external threads, one rod body (12) is in threaded connection with the inside of another rod body (12) to realize expansion, and the outer ends of the rod bodies (12) are provided with hole dies (3). The invention provides simple, practical and potable punching tool equipment for on-site construction of a tunnel.

Description

technical field [0001] The invention relates to a drilling mold in civil construction, in particular to a tooling device used for drilling hard walls or tunnel walls. Background technique [0002] During the construction of electrified railways, it is often necessary to drill holes for expansion bolts or chemical anchor bolts on hard walls, especially tunnel walls. When drilling these holes, due to the constraints of the construction site The drilled holes are dislocated, and the depth and direction of the holes do not meet the design requirements, which affects the quality and progress of the project. The existing tooling that can improve the drilling quality is large in size and heavy in weight and is not suitable for carrying. It is not suitable for civil construction sites. Contents of the invention [0003] The punching die provided by the invention solves the technical problems that existing punching tools are prone to misalignment of punched holes, and the depth and...
