Description

Technical Field

[0001] This utility model relates to a sheet metal folding machine, and more particularly to a front and rear folding head device for a sheet metal profile. Background Technology

[0002] A sheet metal bending machine is a specialized piece of machinery used for bending and forming metal sheets. Most current sheet metal bending machines employ roller bending technology, using a series of pressure rollers to repeatedly press and bend the edge of the sheet metal. These machines are primarily used for bending the left and right sides of the sheet metal, and cannot be used for bending the front and back. Alternatively, when bending is required on all sides, the bending operation must be performed in two stages. If the left and right sides already have existing bending edges, the pressure rollers may interfere with the formed edges during the front and back bending operation. This interference can lead to inaccurate control of the bending position, potentially involving complex operations and adjustments. Interference between left and right bending edges can also reduce bending efficiency and quality. Utility Model Content
