Bender is assisted to iron sheet
Technical Field
The invention relates to a bending machine, in particular to an auxiliary bending machine for an iron sheet.
Background
The iron sheet is a steel sheet with the thickness of 0.2-4 mm produced by a hot rolling or cold rolling method. The width of the iron sheet is 500-2500 mm. According to different purposes, the iron sheet has different materials: common carbon steel, high-quality carbon structural steel, alloy structural steel, carbon tool steel, stainless steel, spring steel, electrical silicon steel and the like. They are mainly used in the automotive industry, the aeronautical industry, the enamel industry, the electrical industry, the mechanical industry and other sectors. Rolled iron sheet is delivered directly, and also pickled, galvanized or tinned.
The sheet iron is actually a very long sheet, supplied in coils, which can be produced on a multi-stand continuous mill, cut to length and then a steel plate, and therefore has a higher productivity than when rolled in single sheets.
In bending at present, need the staff to place iron sheet one side under the clamp plate of flanging machine with the hand usually, rotate the stripper plate with the hand and buckle the iron sheet with the clamp plate cooperation, still need repeat the change limit, troublesome poeration easily causes danger to the staff, and can not guarantee the quality of buckling.
