Description

Technical Field

[0001] The utility model relates to the technical field of corrugated steel gasket manufacturing, in particular to a mold used for processing steel corrugated steel gaskets. Background Art

[0002] Corrugated steel culvert is a new type of building material with compression and tensile properties, light weight, high strength, good sealing performance, low cost and fast construction. With the widespread application of corrugated steel culverts, it has been highly recognized by the engineering community. Because the corrugated steel plate has corrugations, when the concave and convex parts of the corrugated steel plate are connected with bolts, a special concave gasket and convex gasket are required to make the corrugated steel plate and the nut fit tightly to achieve the connection and tightening with the corrugated plate. When processing concave gaskets and convex gaskets in traditional way, the sheet material is generally directly pressed into multiple concave gaskets and convex gaskets. The thickness of the concave gaskets and convex gaskets processed is the same, and the gaskets cannot fit tightly with the nuts. When processing gaskets with one side being arc-shaped and the other side being flat, the processing steps are often complicated, and the processed gaskets are round, and the processing efficiency is low. Therefore, it is necessary to design a mold that can adjust and replace the cutter and is convenient for processing concave gaskets and convex gaskets. Utility Model Content
