Description

Technical Field

[0001] This utility model relates to the field of plate beveling machine technology, and in particular to a reversible plate beveling forming device. Background Technology

[0002] Before welding, the edges of sheet metal need to be beveled according to processing requirements, necessitating the use of a beveling machine. Beveling primarily employs milling and rolling shearing. The difference lies in the cutting tools used: milling uses a milling cutter, while rolling shearing uses a rolling cutter. These two methods result in distinct bevel shapes, allowing workers to choose the appropriate machine based on their specific needs. Currently, most sheet metal beveling machines operate on a single-sided processing method. When double-sided beveling is required, the sheet metal must be flipped to bevel the other side. Since these sheets are typically heavy, flipping is difficult, poses safety hazards, and impacts production efficiency. Utility Model Content
